Because # these files are not distributed they are always rebuilt # at make time; they should therefore not lie in the source # directory. One plan was to support this using # nodist_info_TEXINFOS or something similar. (Doing this # requires some sanity checks. For instance Automake should # not allow: # dist_info_TEXINFOS = foo.texi # nodist_foo_TEXINFOS = included.texi # because a distributed file should never depend on a # non-distributed file.) # # * If .texi files are not distributed, then .info files should # not be distributed either. There are also cases where one # wants to distribute .texi files, but does not want to # distribute the .info files. For instance the Texinfo package # distributes the tool used to build these files; it would # be a waste of space to distribute them. It's not clear # which syntax we should use to indicate that .info files should # not be distributed. Akim Demaille suggested that eventually # we switch to a new syntax: # | Maybe we should take some inspiration from what's already # | done in the rest of Automake. Maybe there is too much # | syntactic sugar here, and you want # | nodist_INFO = bar.info # | dist_bar_info_SOURCES = bar.texi # | bar_texi_DEPENDENCIES = foo.texi # | with a bit of magic to have bar.info represent the whole # | bar*info set. That's a lot more verbose that the current # | situation, but it is # not new, hence the user has less # | to learn. # | # | But there is still too much room for meaningless specs: # | nodist_INFO = bar.info # | dist_bar_info_SOURCES = bar.texi # | dist_PS = bar.ps something-written-by-hand.ps # | nodist_bar_ps_SOURCES = bar.texi # | bar_texi_DEPENDENCIES = foo.texi # | here bar.texi is dist_ in line 2, and nodist_ in 4. # # Back to the point, it should be clear that in order to support # non-distributed .info files, we need to build them in the # build tree, not in the source tree (non-distributed .texi # files are less of a problem, because we do not output build # rules for them). In Automake 1.7 .info build rules have been # largely cleaned up so that .info files get always build in the # build tree, even when distributed. The idea was that # (1) if during a VPATH build the .info file was found to be # absent or out-of-date (in the source tree or in the # build tree), Make would rebuild it in the build tree. # If an up-to-date source-tree of the .info file existed, # make would not rebuild it in the build tree. # (2) having two copies of .info files, one in the source tree # and one (newer) in the build tree is not a problem # because 'make dist' always pick files in the build tree # first. # However it turned out the be a bad idea for several reasons: # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave # like GNU Make on point (1) above. These implementations # of Make would always rebuild .info files in the build # tree, even if such files were up to date in the source # tree. Consequently, it was impossible to perform a VPATH # build of a package containing Texinfo files using these # Make implementations. # (Refer to the Autoconf Manual, section "Limitation of # Make", paragraph "VPATH", item "target lookup", for # an account of the differences between these # implementations.) # * The GNU Coding Standards require these files to be built # in the source-tree (when they are distributed, that is). # * Keeping a fresher copy of distributed files in the # build tree can be annoying during development because # - if the files is kept under CVS, you really want it # to be updated in the source tree # - it is confusing that 'make distclean' does not erase # all files in the build tree. # # Consequently, starting with Automake 1.8, .info files are # built in the source tree again. Because we still plan to # support non-distributed .info files at some point, we # have a single variable ($INSRC) that controls whether # the current .info file must be built in the source tree # or in the build tree. Actually this variable is switched # off in two cases: # (1) For '.info' files that appear to be cleaned; this is for # backward compatibility with package such as Texinfo, # which do things like # info_TEXINFOS = texinfo.txi info-stnd.texi info.texi # DISTCLEANFILES = texinfo texinfo-* info*.info* # # Do not create info files for distribution. # dist-info: # in order not to distribute .info files. # (2) When the undocumented option 'info-in-builddir' is given. # This is done to allow the developers of GCC, GDB, GNU # binutils and the GNU bfd library to force the '.info' files # to be generated in the builddir rather than the srcdir, as # was once done when the (now removed) 'cygnus' option was # given.

For a little more information, see: The master (and probably more up-to-date) copies of the 'config-ml.in' and 'symlink-tree' files are maintained in the GCC development tree at . The same is probably true also for the 'multi.m4' file. README000064400000005234152531507370005440 0ustar00This is Automake, a Makefile generator. It aims to be portable and to conform to the GNU Coding Standards for Makefile variables and targets. See the INSTALL file for detailed information about how to configure and install Automake. Automake is a Perl script. The input files are called Makefile.am. The output files are called Makefile.in; they are intended for use with Autoconf. Automake requires certain things to be done in your configure.ac. Automake comes with extensive documentation; please refer to it for more details about its purpose, features, and usage patterns. This package also includes the "aclocal" program, whose purpose is to generate an 'aclocal.m4' based on the contents of 'configure.ac'. It is useful as an extensible, maintainable mechanism for augmenting autoconf. It is intended that other package authors will write m4 macros which can be automatically used by aclocal. The documentation for aclocal is currently found in the Automake manual. Automake has a test suite. Use "make check" to run it. For more information, see the file t/README. Automake has a page on the web. See: https://www.gnu.org/software/automake/ Automake also has three mailing lists: * automake@gnu.org For general discussions of Automake and its interactions with other configuration/portability tools like Autoconf or Libtool. * bug-automake@gnu.org Where to send bug reports and feature requests. * automake-patches@gnu.org Where to send patches, and discuss the automake development process and the design of new features. To obtain more information about these list, or to subscribe to them, refer to New releases are announced to autotools-announce@gnu.org. If you want to be informed, subscribe to that list by following the instructions at .

README.aclocal000064400000000560152531507370007032 0ustar00This directory is where .m4 files providing third-party autoconf macros can be placed to be automatically found by the aclocal(1) program. The .m4 files placed here could be shared among different versions of aclocal, so be careful. Even if no actual .m4 files are present, this directory is required in order for aclocal to work properly. Please do not remove it. NEWS000064400000372527152531507370005273 0ustar00* WARNING: Future backward-incompatibilities! - Makefile recipes generated by Automake 2.0 will expect to use an 'rm' program that doesn't complain when called without any non-option argument if the '-f' option is given (so that commands like "rm -f" and "rm -rf" will act as a no-op, instead of raising usage errors). This behavior of 'rm' is very widespread in the wild, and it will be required in the next POSIX version: Accordingly, AM_INIT_AUTOMAKE now expands some shell code that checks that the default 'rm' program in PATH satisfies this requirement, aborting the configure process if this is not the case. For the moment, it's still possible to force the configuration process to succeed even with a broken 'rm', that that will no longer be the case for Automake 2.0. - Automake 2.0 will require Autoconf 2.70 or later (which is still unreleased at the moment of writing, but is planned to be released before Automake 2.0 is). - Automake 2.0 will drop support for the long-deprecated 'configure.in' name for the Autoconf input file. You are advised to start using the recommended name 'configure.ac' instead, ASAP. - The ACLOCAL_AMFLAGS special make variable will be fully deprecated in Automake 2.0: it will raise warnings in the "obsolete" category (but still no hard error of course, for compatibilities with the many, many packages that still relies on that variable). You are advised to start relying on the new Automake support for AC_CONFIG_MACRO_DIRS instead (which was introduced in Automake 1.13). - Automake 2.0 will remove support for automatic dependency tracking with the SGI C/C++ compilers on IRIX. The SGI depmode has been reported broken "in the wild" already, and we don't think investing time in debugging and fixing is worthwhile, especially considering that SGI has last updated those compilers in 2006, and retired support for them in December 2013: - Automake 2.0 will remove support for MS-DOS and Windows 95/98/ME (support for them was offered by relying on the DJGPP project). Note however that both Cygwin and MSYS/MinGW on modern Windows versions will continue to be fully supported. - Automake-provided scripts and makefile recipes might (finally!) start assuming a POSIX shell in Automake 2.0. There still is no certainty about this though: we'd first like to wait and see whether future Autoconf versions will be enhanced to guarantee that such a shell is always found and provided by the checks in ./configure. - Starting from Automake 2.0, third-party m4 files located in the system-wide aclocal directory, as well as in any directory listed in the ACLOCAL_PATH environment variable, will take precedence over "built-in" Automake macros. For example (assuming Automake is installed in the /usr/local hierarchy), a definition of the AM_PROG_VALAC macro found in '/usr/local/share/aclocal/my-vala.m4' should take precedence over the same-named automake-provided macro (defined in '/usr/local/share/aclocal-2.0/vala.m4'). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.16.1: * Bugs fixed: - 'install-sh' now ensures that nobody can cross privilege boundaries by pre-creating symlink on the directory inside "/tmp". - 'automake' does not depend on the 'none' subroutine of the List::Util module anymore to support older Perl version. (automake bug#30631) - A regression in AM_PYTHON_PATH causing the rejection of non literal minimum version parameter hasn't been fixed. (automake bug#30616) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.16: * Miscellaneous changes - When subdir-objects is in effect, Automake will now construct shorter object file names when no programs and libraries name clashes are encountered. This should make the discouraged use of 'foo_SHORTNAME' unnecessary in many cases. * Bugs fixed: - Automatic dependency tracking has been fixed to work also when the 'subdir-object' option is used and some 'foo_SOURCES' definition contains unexpanded references to make variables, as in, e.g.: a_src = sources/libs/aaa b_src = sources/bbb foo_SOURCES = $(a_src)/bar.c $(b_src)/baz.c With such a setup, the created makefile fragment containing dependency tracking information will be correctly placed under the directories named 'sources/libs/aaa/.deps' and 'sources/bbb/.deps', rather than mistakenly under directories named (literally!) '$(src_a)/.deps' and '$(src_b)/.deps' (this was the first part of automake bug#13928). Notice that in order to fix this bug we had to slightly change the semantics of how config.status bootstraps the makefile fragments required for the dependency tracking to work: rather than attempting to parse the Makefiles via grep and sed trickeries only, we actually invoke 'make' on a slightly preprocessed version of those Makefiles, using a private target that is only meant to bootstrap the required makefile fragments. - The 'subdir-object' option no longer causes object files corresponding to source files specified with an explicit '$(srcdir)' component to be placed in the source tree rather than in the build tree. For example, if Makefile.am contains: AUTOMAKE_OPTIONS = subdir-objects foo_SOURCES = $(srcdir)/foo.c $(srcdir)/s/bar.c $(top_srcdir)/baz.c then "make all" will create 'foo.o' and 's/bar.o' in $(builddir) rather than in $(srcdir), and will create 'baz.o' in $(top_builddir) rather than in $(top_srcdir). This was the second part of automake bug#13928. - Installed 'aclocal' m4 macros can now accept installation directories containing '@' characters (automake bug#20903) - "./configure && make dist" no longer fails when a distributed file depends on one from BUILT_SOURCES. - When combining AC_LIBOBJ or AC_FUNC_ALLOCA with the "--disable-dependency-tracking" configure option in an out of source build, the build sub-directory defined by AC_CONFIG_LIBOBJ_DIR is now properly created. (automake bug#27781) - The time printed by 'mdate-sh' is now using the UTC time zone to support the reproducible build effort. (automake bug#20314) - The elisp byte-compilation rule now uses byte-compile-dest-file-function, rather than byte-compile-dest-file, which was obsoleted in 2009. We expect that Emacs-26 will continue to support the old function, but will complain loudly, and that Emacs-27 will remove support for it altogether. * New features added - A custom testsuite driver for the Guile Scheme SRFI-64 API has been added to the "contrib" section. This allows a more convenient way to test Guile code without having to use low primitives such as exit status. See SRFI-64 API specification for more details: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.15.1: * Bugs fixed: - The code has been adapted to remove a warning present since Perl 5.22 stating that "Unescaped left brace in regex is deprecated". This warning has become an hard error in Perl 5.26 (bug#22372). - The generated Makefiles do not rely on the obsolescent GZIP environment variable which was used for passing arguments to 'gzip'. Compatibility with old versions has been preserved. (bug#20132) * Miscellaneous changes: - Support the Windows version of the Intel C Compiler (icl) in the 'compile' script in the same way the (compatible) Microsoft C Compiler is supported. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.15: * Improvements and refactorings in the install-sh script: - It has been modernized, and now makes the following assumptions *unconditionally*: (1) a working 'dirname' program is available; (2) the ${var:-value} shell parameters substitution works; (3) the "set -f" and "set +f" shell commands work, and, respectively, disable and enable shell globbing. - The script implements stricter error checking, and now it complains and bails out if any of the following expectations is not met: (1) the options -d and -t are never used together; (2) the argument passed to option -t is a directory; (3) if there are two or more SOURCEFILE arguments, the DESTINATION argument must be a directory. * Automake-generated testsuites: - The default test-driver used by the Automake-generated testsuites now appends the result and exit status of each "plain" test to the associated log file (automake bug#11814). - The perl implementation of the TAP testsuite driver is no longer installed in the Automake's scripts directory, and is instead just distributed as a "contrib" addition. There should be no reason to use this implementation anyway in real packages, since the awk+shell implementation of the TAP driver (which is documented in the manual) is more portable and has feature parity with the perl implementation. - The rule generating 'test-suite.log' no longer risk incurring in an extra useless "make all" recursive invocation in some corner cases (automake bug#16302). * Distribution: - Automake bug#18286: "make distcheck" could sometimes fail to detect files missing from the distribution tarball, especially in those cases where both the generated files and their dependencies are explicitly in $(srcdir). An important example of this are *generated* makefile fragments included at Automake time in Makefile.am; e.g.: ... $(srcdir)/fragment.am: $(srcdir)/data.txt $(srcdir)/preproc.sh cd $(srcdir) && $(SHELL) preproc.sh fragment.am include $(srcdir)/fragment.am ... If the use forgot to add data.txt and/or preproc.sh in the distribution tarball, "make distcheck" would have erroneously succeeded! This issue is now fixed. - As a consequence of the previous change, "make distcheck" will run using '$(distdir)/_build/sub' as the build directory, rather than simply '$(distdir)/_build' (as it was the case for Automake 1.14 and earlier). Consequently, the './configure' and 'make' invocations issued by the distcheck recipe now have $(srcdir) equal to '../..', rather than to just '..'. Dependent and similar variables (e.g., '$(top_srcdir)') are also changed accordingly. Thus, Makefiles that made assumptions about the exact values of the build and source directories used by "make distcheck" will have to be adjusted. Notice that making such assumptions was a bad and unsupported practice anyway, since the exact locations of those directories should be considered implementation details, and we reserve the right to change them at any time. * Miscellaneous bugs fixed: - The expansion of AM_INIT_AUTOMAKE ends once again with a trailing newline (bug#16841). Regression introduced in Automake 1.14. - We no longer risk to use '$ac_aux_dir' before it's defined (see automake bug#15981). Bug introduced in Automake 1.14. - The code used to detect whether the currently used make is GNU make or not (relying on the private macro 'am__is_gnu_make') no longer risks causing "Arg list too long" for projects using automatic dependency tracking and having a ton of source files (bug#18744). - Automake tries to offer a more deterministic output for generated Makefiles, in the face of the newly-introduced randomization for hash keys order in Perl 5.18. - In older Automake versions, if a user defined one single Makefile fragment (say 'foo.am') to be included via Automake includes in his main Makefile.am, and defined a custom make rule to generate that file from other data, Automake used to spuriously complain with some message like "... overrides Automake target '$(srcdir)/foo.am". This bug is now fixed. - The user can now extend the special .PRECIOUS target, the same way he could already do with the .MAKE .and .PHONY targets. - Some confusing typos have been fixed in the manual and in few warning messages (automake bug#16827 and bug#16997). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.14.1: * Bugs fixed: - The user is no longer allowed to override the --srcdir nor the --prefix configure options used by "make distcheck" (bug#14991). - Fixed a gross inefficiency in the recipes for installing byte-compiled python files, that was causing an O(N^2) performance on the number N of files, instead of the expected O(N) performance. Note that this bug was only relevant when the number of python files was high (which is unusual in practice). - Automake try to offer a more deterministic output for warning messages, in the face of the newly-introduced randomization for hash keys order in Perl 5.18. - The 'test-driver' script now actually error out with a clear error message on the most common invalid usages. - Several spurious failures/hangs in the testsuite (bugs #14706, #14707, #14760, #14911, #15181, #15237). * Documentation fixes: - Fixed typos in the 'fix-timestamp.sh' example script that made it nonsensical. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.14: * C compilation, and the AC_PROG_CC and AM_PROG_CC_C_O macros: - The 'compile' script is now unconditionally required for all packages that perform C compilation (if you are using the '--add-missing' option, automake will fetch that script for you, so you shouldn't need any explicit adjustment). This new behaviour is needed to avoid obscure errors when the 'subdir-objects' option is used, and the compiler is an inferior one that doesn't grasp the combined use of both the "-c -o" options; see discussion about automake bug#13378 for more details: - The next major Automake version (2.0) will unconditionally activate the 'subdir-objects' option. In order to smooth out the transition, we now give a warning (in the category 'unsupported') whenever a source file is present in a subdirectory but the 'subdir-object' is not enabled. For example, the following usage will trigger such a warning: bin_PROGRAMS = sub/foo sub_foo_SOURCES = sub/main.c sub/bar.c - Automake will automatically enhance the autoconf-provided macro AC_PROG_CC to force it to check, at configure time, that the C compiler supports the combined use of both the '-c' and '-o' options. The result of this check is saved in the cache variable 'am_cv_prog_cc_c_o', and said result can be overridden by pre-defining that variable. - The AM_PROG_CC_C_O macro can still be called, albeit that should no longer be necessary. This macro is now just a thin wrapper around the Automake-enhanced AC_PROG_CC. This means, among the other things, that its behaviour is changed in three ways: 1. It no longer invokes the Autoconf-provided AC_PROG_CC_C_O macro behind the scenes. 2. It caches the check result in the 'am_cv_prog_cc_c_o' variable, and not in a 'ac_cv_prog_cc_*_c_o' variable whose exact name is dynamically computed only at configure runtime (really!) from the content of the '$CC' variable. 3. It no longer automatically AC_DEFINE the C preprocessor symbol 'NO_MINUS_C_MINUS_O'. * Texinfo support: - Automake can now be instructed to place '.info' files generated from Texinfo input in the builddir rather than in the srcdir; this is done specifying the new automake option 'info-in-builddir'. This feature was requested by the developers of GCC, GDB, GNU binutils and the GNU bfd library. See the extensive discussion about automake bug#11034 for more details. - For quite a long time, Automake has been implementing an undocumented hack which ensured that '.info' files which appeared to be cleaned (by being listed in the CLEANFILES or DISTCLEANFILES variables) were built in the builddir rather than in the srcdir; this hack was introduced to ensure better backward-compatibility with package such as Texinfo, which do things like: info_TEXINFOS = texinfo.txi info-stnd.texi info.texi DISTCLEANFILES = texinfo texinfo-* info*.info* # Do not create info files for distribution. dist-info: @: in order not to distribute generated '.info' files. Now that we have the 'info-in-builddir' option that explicitly causes generated '.info' files to be placed in the builddir, this hack should be longer necessary, so we deprecate it with runtime warnings. It will be removed altogether in Automake 2.0. * Relative directory in Makefile fragments: - The special Automake-time substitutions '%reldir%' and '%canon_reldir%' (and their short versions, '%D%' and '%C%' respectively) can now be used in an included Makefile fragment. The former is substituted with the relative directory of the included fragment (compared to the top-level including Makefile), and the latter with the canonicalized version of the same relative directory. # in 'Makefile.am': bin_PROGRAMS = # will be updated by included Makefile fragments include src/Makefile.inc # in 'src/Makefile.inc': bin_PROGRAMS += %reldir%/foo %canon_reldir%_foo_SOURCES = %reldir%/bar.c This should be especially useful for packages using a non-recursive build system. * Deprecated distribution formats: - The 'shar' and 'compress' distribution formats are deprecated, and scheduled for removal in Automake 2.0. Accordingly, the use of the 'dist-shar' and 'dist-tarZ' will cause warnings at automake runtime (in the 'obsolete' category), and the recipes of the Automake-generated targets 'dist-shar' and 'dist-tarZ' will unconditionally display (non-fatal) warnings at make runtime. * New configure runtime warnings about "rm -f" support: - To simplify transition to Automake 2.0, the shell code expanded by AM_INIT_AUTOMAKE now checks (at configure runtime) that the default 'rm' program in PATH doesn't complain when called without any non-option argument if the '-f' option is given (so that commands like "rm -f" and "rm -rf" act as a no-op, instead of raising usage errors). If this is not the case, the configure script is aborted, to call the attention of the user on the issue, and invite him to fix his PATH. The checked 'rm' behavior is very widespread in the wild, and will be required by future POSIX versions: The user can still force the configure process to complete even in the presence of a broken 'rm' by defining the ACCEPT_INFERIOR_RM_PROGRAM environment variable to "yes". And the generated Makefiles should still work correctly even when such broken 'rm' is used. But note that this will no longer be the case with Automake 2.0 though, so, if you encounter the warning, please report it to us ASAP (and try to fix your environment as well). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.13.4: * Bugs fixed: - Fix a minor regression introduced in Automake 1.13.3: when two or more user-defined suffix rules were present in a single Makefile.am, automake would needlessly include definition of some make variables related to C compilation in the generated Makefile.in (bug#14560). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.13.3: * Documentation fixes: - The documentation no longer mistakenly reports that the obsolete 'AM_MKDIR_PROG_P' macro and '$(mkdir_p)' make variable are going to be removed in Automake 2.0. * Bugs fixed: - Byte-compilation of Emacs lisp files could fail spuriously on Solaris, when /bin/ksh or /usr/xpg4/bin/sh were used as shell. - If the same user-defined suffixes were transformed into different Automake-known suffixes in different Makefile.am files in the same project, automake could get confused and generate inconsistent Makefiles (automake bug#14441). For example, if 'Makefile.am' contained a ".ext.cc:" suffix rule, and 'sub/Makefile.am' contained a ".ext.c:" suffix rule, automake would have mistakenly placed into 'Makefile.in' rules to compile "*.c" files into object files, and into 'sub/Makefile.in' rules to compile "*.cc" files into object files --- rather than the other way around. This is now fixed. * Testsuite work: - The test cases no longer have the executable bit set. This should make it clear that they are not meant to be run directly; as explained in t/README, they can only be run through the custom 'runtest' script, or by a "make check" invocation. - The testsuite has seen the introduction of a new helper function 'run_make', and several related changes. These serve a two-fold purpose: 1. Remove brittleness due to the use of "make -e" in test cases. 2. Seamlessly allow the use of parallel make ("make -j...") in the test cases, even where redirection of make output is involved (see automake bug#11413 for a description of the subtle issues in this area). - Several spurious failures have been fixed (they hit especially MinGW/MSYS builds). See automake bugs #14493, #14494, #14495, #14498, #14499, #14500, #14501, #14517 and #14528. - Some other minor miscellaneous changes and fixlets. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.13.2: * Documentation fixes: - The long-deprecated but still supported two-arguments invocation form of AM_INIT_AUTOMAKE is documented once again. This seems the sanest thing to do, given that support for such usage might need to remain in place for an unspecified amount of time in order to cater to people who want to define the version number for their package dynamically at configure runtime (unfortunately, Autoconf does not yet support this scenario, so we cannot delegate the work to it). - The serial testsuite harness is no longer reported as "deprecated", but as "discouraged". We have no plan to remove it, nor to make its use cause runtime warnings. - The parallel testsuite is no longer reported as "experimental"; it is well tested, and should be stable now. - The 'shar' and 'tarZ' distribution formats and the 'dist-shar' and 'dist-tarZ' options are obsolescent, and their use is deprecated in the documentation. - Other minor miscellaneous fixes and improvements; in particular, some improvements in cross-references. * Obsolescent features: - Use of suffix-less info files (that can be specified through the '@setfilename' macro in Texinfo input files) is discouraged, and its use will raise warnings in the 'obsolete' category. Simply use the '.info' extension for all your info files, transforming usages like: @setfilename myprogram into: @setfilename myprogram.info - Use of Texinfo input files with '.txi' or '.texinfo' extensions is discouraged, and its use will raise warnings in the 'obsolete' category. You are advised to simply use the '.texi' extension instead. * Bugs fixed: - When the 'ustar' option is used, the generated configure script no longer risks hanging during the tests for the availability of the 'pax' utility, even if the user running configure has a UID or GID that requires more than 21 bits to be represented. See automake bug#8343 and bug#13588. - The obsolete macros AM_CONFIG_HEADER or AM_PROG_CC_STDC work once again, as they did in Automake 1.12.x (albeit printing runtime warnings in the 'obsolete' category). Removing them has turned out to be a very bad idea, because it complicated distro packing enormously. Making them issue fatal warnings, as we did in Automake 1.13, has turned out to be a similarly very bad idea, for exactly the same reason. - aclocal will no longer error out if the first local m4 directory (as specified by the '-I' option or the 'AC_CONFIG_MACRO_DIRS' or 'AC_CONFIG_MACRO_DIR' macros) doesn't exist; it will merely report a warning in the 'unsupported' category. This is done to support some pre-existing real-world usages. See automake bug#13514. - aclocal will no longer consider directories for extra m4 files more than once, even if they are specified multiple times. This ensures packages that specify both AC_CONFIG_MACRO_DIR([m4]) in configure.ac ACLOCAL_AMFLAGS = -I m4 in Makefile.am will work correctly, even when the 'm4' directory contains no package-specific files, but is used only to install third-party m4 files (as can happen with e.g., "libtoolize --install"). See automake bug#13514. - Analysis of make flags in Automake-generated rules has been made more robust, and more future-proof. For example, in presence of make that (like '-I') take an argument, the characters in said argument will no longer be spuriously considered as a set of additional make options. In particular, automake-generated rules will no longer spuriously believe to be running in dry mode ("make -n") if run with an invocation like "make -I noob"; nor will they believe to be running in keep-going mode ("make -k") if run with an invocation like "make -I kool" (automake bug#12554). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.13.1: * Bugs fixed: - Use of the obsolete macros AM_CONFIG_HEADER or AM_PROG_CC_STDC now causes a clear and helpful error message, instead of obscure ones (issue introduced in Automake 1.13). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.13: * Bugs fixed: - ylwrap renames properly header guards in generated header files (*.h), instead of leaving Y_TAB_H. - ylwrap now also converts header guards in implementation files (*.c). Because ylwrap failed to rename properly #include in the implementation files, current versions of Bison (e.g., 2.7) duplicate the generated header file in the implementation file. The header guard then protects the implementation file from duplicate definitions from the header file. * Version requirements: - Autoconf 2.65 or greater is now required. - The rules to build PDF and DVI output from Texinfo input now require Texinfo 4.9 or later. * Obsolete features: - Support for the "Cygnus-style" trees (once enabled by the 'cygnus' option) has been removed. See discussion about automake bug#11034 for more background: . - The deprecated aclocal option '--acdir' has been removed. You should use the options '--automake-acdir' and '--system-acdir' instead (which have been introduced in Automake 1.11.2). - The following long-obsolete m4 macros have been removed: AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part of the now-removed automatic de-ANSI-fication support of Automake) - All the "old alias" macros in 'm4/obsolete.m4' have been removed. - Use of the long-deprecated two- and three-arguments invocation forms of the AM_INIT_AUTOMAKE is no longer documented. It's still supported though (albeit with a warning in the 'obsolete' category), to cater for people who want to define the version number for their package dynamically (e.g., from the current VCS revision). We'll have to continue this support until Autoconf itself is fixed to allow better support for such dynamic version numbers. * Elisp byte-compilation: - The byte compilation of '.el' files into '.elc' files is now done with a suffix rule. This has simplified the compilation process, and more importantly made it less brittle. The downside is that emacs is now invoked once for each '.el' files, which cause some noticeable slowdowns. These should however be mitigated on multicore machines (which are becoming the norm today) if concurrent make ("make -j") is used. - Elisp files placed in a subdirectory are now byte-compiled to '.elc' files in the same subdirectory; for example, byte-compiling of file 'sub/foo.el' file will result in 'sub/foo.elc' rather than in 'foo.elc'. This behaviour is backward-incompatible with older Automake versions, but it is more natural and more sane. See also automake bug#7441. - The Emacs invocation performing byte-compilation of '.el' files honors the $(AM_ELCFLAGS) and $(ELCFLAGS) variables; as typical, the former one is developer-reserved and the latter one user-reserved. - The 'elisp-comp' script, once provided by Automake, has been rendered obsoleted by the just-described changes, and thus removed. * Changes to Automake-generated testsuite harnesses: - The parallel testsuite harness (previously only enabled by the 'parallel-tests' option) is the default one; the older serial testsuite harness will still be available through the use of the 'serial-tests' option (introduced in Automake 1.12). - The 'color-tests' option is now unconditionally activated by default. In particular, this means that testsuite output is now colorized by default if the attached terminal seems to support ANSI escapes, and that the user can force output colorization by setting the variable AM_COLOR_TESTS to "always". The 'color-tests' is still recognized for backward-compatibility, although it's a handled as a no-op now. * Silent rules support: - Support for silent rules is now always active in Automake-generated Makefiles. So, although the verbose output is still the default, the user can now always use "./configure --enable-silent-rules" or "make V=0" to enable quieter output in the package he's building. - The 'silent-rules' option has now become a no-op, preserved for backward-compatibility only. In particular, its use no longer disables the warnings in the 'portability-recursive' category. * Texinfo Support: - The rules to build PDF and DVI files from Texinfo input now require Texinfo 4.9 or later. - The rules to build PDF and DVI files from Texinfo input now use the '--build-dir' option, to keep the auxiliary files used by texi2dvi and texi2pdf around without cluttering the build directory, and to make it possible to run the "dvi" and "pdf" recipes in parallel. * Automatic remake rules and 'missing' script: - The 'missing' script no longer tries to update the timestamp of out-of-date files that require a maintainer-specific tool to be remade, in case the user lacks such a tool (or has a too-old version of it). It just gives a useful warning, and in some cases also a tip about how to obtain such a tool. - The missing script has thus become useless as a (poor) way to work around the sketched-timestamps issues that can happen for projects that keep generated files committed in their VCS repository. Such projects are now encouraged to write a custom "fix-timestamps.sh" script to avoid such issues; a simple example is provided in the "CVS and generated files" chapter of the automake manual. * Recursive targets: - The user can now define his own recursive targets that recurse in the directories specified in $(SUBDIRS). This can be done by specifying the name of such targets in invocations of the new 'AM_EXTRA_RECURSIVE_TARGETS' m4 macro. * Tags: - Any failure in the recipe of the "tags", "ctags", "cscope" or "cscopelist" targets in a subdirectory is now propagated to the top-level make invocation. - Tags are correctly computed also for files in _SOURCES variables that only list files with non-standard suffixes (see automake bug#12372). * Improvements to aclocal and related rebuilds rules: - Autoconf-provided macros AC_CONFIG_MACRO_DIR and AC_CONFIG_MACRO_DIRS are now traced by aclocal, and can be used to declare the local m4 include directories. Formerly, one had to specify it with an explicit '-I' option to the 'aclocal' invocation. - The special make variable ACLOCAL_AMFLAGS is deprecated; future Automake versions will warn about its use, and later version will remove support for it altogether. * The depcomp script: - Dropped support for libtool 1.4. - Various internal refactorings. They should cause no visible change, but the chance for regression is there anyway, so please report any unexpected or suspicious behaviour. - Support for pre-8.0 versions of the Intel C Compiler has been dropped. This should cause no problem, since icc 8.0 has been released in December 2003 -- almost nine years ago. - Support for tcc (the Tiny C Compiler) has been improved, and is now handled through a dedicated 'tcc' mode. * The ylwrap script: - ylwrap generates header guards with a single '_' for series of non alphabetic characters, instead of several. This is what Bison >= 2.5.1 does. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bugs fixed in 1.12.6: * Python-related bugs: - The default installation location for python modules has been improved for Python 3 on Debian and Ubuntu systems, changing from: ${prefix}/lib/python3/dist-packages to ${prefix}/lib/python3.x/site-packages This change should ensure modules installed using the default ${prefix} "/usr/local" are found by default by system python 3.x installations. See automake bug#10227. - Python byte-compilation supports the new layout mandated by PEP-3147, with its __pycache__ directory (automake bug#8847). * Build system issues: - The maintainer rebuild rules for Makefiles and aclocal.m4 in Automake's own build system works correctly again (bug introduced in Automake 1.12.5). * Testsuite issues: - The Vala-related tests has been changed to adjust to the removal of the 'posix' profile in the valac compiler. See automake bug#12934 a.k.a. bug#12522. - Some spurious testsuite failures related to older tools and systems have been fixed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.12.5: * Vala support: - The AM_PROG_VALAC macro has been enhanced to takes two further optional arguments; it's signature now being AM_PROG_VALAC([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND]) - By default, AM_PROG_VALAC no longer aborts the configure invocation if the Vala compiler found is too old, but simply prints a warning messages (as it did when the Vala compiler was not found). This should avoid unnecessary difficulties for end users that just want to compile the unmodified, distributed Vala-generated C sources, but happens to have an old Vala compiler in their PATH. This fixes automake bug#12688. - If no proper Vala compiler is found at configure runtime, AM_PROG_VALAC will set the AC_SUBST'd variable 'VALAC' to 'valac' rather than to ':'. This is a better default, because with it a triggered makefile rule invoking a Vala compilation will clearly fail with an informative error message like "valac: command not found", rather than silently, with the error possibly going unnoticed or triggering harder-to-diagnose fallout failures in later steps. * Miscellaneous changes: - automake and aclocal no longer honours the 'perllibdir' environment variable. That had always been intended only as an hack required in the testsuite, not meant for any use beyond that. Bugs fixed in 1.12.5: * Long-standing bugs: - Automake no longer generates spurious remake rules invoking autoheader to regenerate the template corresponding to header files specified after the first one in AC_CONFIG_HEADERS (automake bug#12495). - When wrapping Microsoft tools, the 'compile' script falls back to finding classic 'libname.a' style libraries when 'name.lib' and 'name.dll.lib' aren't available. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.12.4: * Warnings and deprecations: - Warnings in the 'obsolete' category are enabled by default both in automake and aclocal. * Miscellaneous changes: - Some testsuite weaknesses and spurious failures have been fixed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.12.3: * Miscellaneous changes: - The '.m4' files provided by Automake no longer define serial numbers. This should cause no difference in the behaviour of aclocal though. - Some testsuite weaknesses and spurious failures have been fixed. - There is initial support for automatic dependency tracking with the Portland Group C/C++ compilers, thanks to the new new depmode 'pgcc'. Bugs fixed in 1.12.3: * Long-standing bugs: - Instead of renaming only self-references of files (typically for #lines), ylwrap now also renames references to the other generated files. This fixes support for GLR and C++ parsers from Bison (PR automake/491 and automake bug#7648): 'parser.c' now properly #includes 'parser.h' instead of 'y.tab.h'. - Generated files unknown to ylwrap are now preserved. This fixes C++ support for Bison (automake bug#7648): location.hh and the like are no longer discarded. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.12.2: * Warnings and deprecations: - Automake now issues a warning (in the 'portability' category) if 'configure.in' is used instead of 'configure.ac' as the Autoconf input file. Such a warning will also be present in the next Autoconf version (2.70). * Cleaning rules: - Recursive cleaning rules descends into the $(SUBDIRS) in the natural order (as done by the other recursive rules), rather than in the inverse order. They used to do that in order to work a round a limitation in an older implementation of the automatic dependency tracking support, but that limitation had been lifted years ago already, when the automatic dependency tracking based on side-effects of compilation had been introduced. - Cleaning rules for compiled objects (both "plain" and libtool) work better when subdir objects are involved, not triggering a distinct 'rm' invocation for each such object. They do so by removing *any* compiled object file that is in the same directory of a subdir object. See automake bug#10697. * Silent rules support: - A new predefined $(AM_V_P) make variable is provided; it expands to a shell conditional that can be used in recipes to know whether make is being run in silent or verbose mode. Bugs fixed in 1.12.2: * SECURITY VULNERABILITIES! - The 'distcheck' recipe no longer grants temporary world-write permissions on the extracted distdir. Even if such rights were only granted for a vanishingly small time window, the implied race condition proved to be enough to allow a local attacker to run arbitrary code with the privileges of the user running "make distcheck". This is CVE-2012-3386. * Long-standing bugs: - The "recheck" targets behaves better in the face of build failures related to previously failed tests. For example, if a test is a compiled program that must be rerun by "make recheck", and its compilation fails, it will still be rerun by further "make recheck" invocations. See automake bug#11791. * Bugs introduced by 1.12.1: - Automake provides once again the '$(mkdir_p)' make variable and the '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'), for better backward-compatibility. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.12.1: * New supported languages: - Support for Objective C++ has been added; it should work similarly to the support for Objective C. * Deprecated obsolescent features: - Use of the long-deprecated two- and three-arguments invocation forms of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete' category. Starting from some future major Automake release (likely post-1.13), such usages will no longer be allowed. - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is now deprecated (its use triggers a warning in the 'obsolete' category). It will be removed in the next major Automake release (1.13). - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR m4 macro are deprecated, eliciting a warning in the 'obsolete' category. * Miscellaneous changes: - The Automake test cases now require a proper POSIX-conforming shell. Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) will no longer be accepted. In most cases, the user shouldn't have to specify such POSIX shell explicitly, since it will be looked up at configure time. Still, when this lookup fails, or when the user wants to override its conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be used (pointing to the shell that will be used to run the Automake test cases). Bugs fixed in 1.12.1: * Bugs introduced by 1.12: - Several weaknesses in Automake's own build system and test suite have been fixed. * Bugs introduced by 1.11.3: - When given non-option arguments, aclocal rejects them, instead of silently ignoring them. * Long-standing bugs: - When the 'color-tests' option is in use, forcing of colored testsuite output through "AM_COLOR_TESTS=always" works even if the terminal is a non-ANSI one, i.e., if the TERM environment variable has a value of "dumb". - Several inefficiencies and poor performances in the implementation of the parallel-tests 'check' and 'recheck' targets have been fixed. - The post-processing of output "#line" directives done the ylwrap script is more faithful w.r.t. files in a subdirectory; for example, if the processed file is "src/grammar.y", ylwrap will correctly produce directives like: #line 7 "src/grammar.y" rather than like #line 7 "grammar.y" as it did before. * Bugs with new Perl versions: - Aclocal works correctly with perl 5.16.0 (automake bug#11543). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.12: * Obsolete features removed: - The never documented nor truly used script 'acinstall' has been removed. - Support for automatic de-ANSI-fication has been removed. - The support for the "obscure" multilib feature has been removed from Automake core (but remains available in the 'contrib/' directory of the Automake distribution). - Support for ".log -> .html" conversion and the check-html and recheck-html targets has been removed from Automake core (but remains available in the 'contrib/' directory of the Automake distribution). - The deprecated 'lzma' compression format for distribution archives has been removed, in favor of 'xz' and 'lzip'. - The obsolete AM_WITH_REGEX macro has been removed. - The long-deprecated options '--output-dir', '--Werror' and '--Wno-error' have been removed. - The chapter on the history of Automake has been moved out of the reference manual, into a new dedicated Texinfo file. * New targets: - New 'cscope' target to build a cscope database for the source tree. * Changes to Automake-generated testsuite harnesses: - The new automake option 'serial-tests' has been introduced. It can be used to explicitly instruct automake to use the older serial testsuite harness. This is still the default at the moment, but it might change in future versions. - The 'recheck' target (provided by the parallel testsuite harness) now depends on the 'all' target. This allows for a better user-experience in test-driven development. See automake bug#11252. - Test scripts that exit with status 99 to signal an "hard error" (e.g., and unexpected or internal error, or a failure to set up the test case scenario) have their outcome reported as an 'ERROR' now. Previous versions of automake reported such an outcome as a 'FAIL' (the only difference with normal failures being that hard errors were counted as failures even when the test originating them was listed in XFAIL_TESTS). - The testsuite summary displayed by the parallel-test harness has a completely new format, that always list the numbers of passed, failed, xfailed, xpassed, skipped and errored tests, even when these numbers are zero (but using smart coloring when the color-tests option is in effect). - The default testsuite driver offered by the 'parallel-tests' option is now implemented (partly at least) with the help of automake-provided auxiliary scripts (e.g., 'test-driver'), instead of relying entirely on code in the generated Makefile.in. This has two noteworthy implications. The first one is that projects using the 'parallel-tests' option should now either run automake with the '--add-missing' option, or manually copy the 'test-driver' script into their tree. The second, and more important, implication is that now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can no longer be used to define a test runner, and the command specified in LOG_COMPILER (and _LOG_COMPILER) must be a *real* executable program or script. For example, this is still a valid usage (albeit a little contorted): TESTS_ENVIRONMENT = \ if test -n '$(STRICT_TESTS)'; then \ maybe_errexit='-e'; \ else \ maybe_errexit=''; \ fi; LOG_COMPILER = $(SHELL) $$maybe_errexit OTOH, this is no longer a valid usage: TESTS_ENVIRONMENT = \ $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'` neither is this: TESTS_ENVIRONMENT = \ run_with_perl_or_shell () \ { \ if grep -q '^#!.*perl' $$1; then $(PERL) $$1; \ else \ $(SHELL) $$1; \ fi; \ } LOG_COMPILER = run_with_perl_or_shell - The package authors can now use customary testsuite drivers within the framework provided by the 'parallel-tests' testsuite harness. Consistently with the existing syntax, this can be done by defining special makefile variables 'LOG_DRIVER' and '_LOG_DRIVER'. - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used to redirect/define file descriptors used by the test scripts. - The parallel-tests harness generates now, in addition the '.log' files holding the output produced by the test scripts, a new set of '.trs' files, holding "metadata" derived by the execution of the test scripts; among such metadata are the outcomes of the test cases run by a script. - Initial and still experimental support for the TAP test protocol is now provided. * Changes to Yacc and Lex support: - C source and header files derived from non-distributed Yacc and/or Lex sources are now removed by a simple "make clean" (while they were previously removed only by "make maintainer-clean"). - Slightly backward-incompatible change, relevant only for use of Yacc with C++: the extensions of the header files produced by the Yacc rules are now modelled after the extension of the corresponding sources. For example, yacc files named "foo.y++" and "bar.yy" will produce header files named "foo.h++" and "bar.hh" respectively, where they would have previously produced header files named simply "foo.h" and "bar.h". This change offers better compatibility with 'bison -o'. * Miscellaneous changes: - The AM_PROG_VALAC macro now causes configure to exit with status 77, rather than 1, if the vala compiler found is too old. - The build system of Automake itself now avoids the use of make recursion as much as possible. - Automake now prefers to quote 'like this' or "like this", rather than `like this', in diagnostic message and generated Makefiles, to accommodate the new GNU Coding Standards recommendations. - Automake has a new option '--print-libdir' that prints the path of the directory containing the Automake-provided scripts and data files. - The 'dist' and 'dist-all' targets now can run compressors in parallel. - The rules to create pdf, dvi and ps output from Texinfo files now works better with modern 'texi2dvi' script, by explicitly passing it the '--clean' option to ensure stray auxiliary files are not left to clutter the build directory. - Automake can now generate silenced rules for texinfo outputs. - Some auxiliary files that are automatically distributed by Automake (e.g., 'install-sh', or the 'depcomp' script for packages compiling C sources) might now be listed in the DIST_COMMON variable in many Makefile.in files, rather than in the top-level one. - Messages of types warning or error from 'automake' and 'aclocal' are now prefixed with the respective type, and presence of -Werror is noted. - Automake's early configure-time sanity check now tries to avoid sleeping for a second, which slowed down cached configure runs noticeably. In that case, it will check back at the end of the configure script to ensure that at least one second has passed, to avoid time stamp issues with makefile rules rerunning autotools programs. - The warnings in the category 'extra-portability' are now enabled by '-Wall'. In previous versions, one has to use '-Wextra-portability' to enable them. Bugs fixed in 1.12: - Various minor bugfixes for recent or long-standing bugs. * Bugs introduced by 1.11: - The AM_COND_IF macro also works if the shell expression for the conditional is no longer valid for the condition. - The automake-provided parallel testsuite harness no longer fails with BSD make used in parallel mode when there are test scripts in a subdirectory, like in: TESTS = sub/foo.test sub/bar.test * Long-standing bugs: - Automake's own build system finally have a real "installcheck" target. - Vala-related cleanup rules are now more complete, and work better in a VPATH setup. - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are now automatically distributed also if the directory of the auxiliary files coincides with the top-level directory. - Automake now detects the presence of the '-d' flag in the various '*YFLAGS' variables even when their definitions involve indirections through other variables, such as in: foo_opts = -d AM_YFLAGS = $(foo_opts) - Automake now complains if a '*YFLAGS' variable has any conditional content, not only a conditional definition. - Explicit enabling and/or disabling of Automake warning categories through the '-W...' options now always takes precedence over the implicit warning level implied by Automake strictness (foreign, gnu or gnits), regardless of the order in which such strictness and warning flags appear. For example, a setting like: AUTOMAKE_OPTIONS = -Wall --foreign will cause the warnings in category 'portability' to be enabled, even if those warnings are by default disabled in 'foreign' strictness. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bugs fixed in 1.11.5: * Bugs introduced by 1.11.3: - Vala files with '.vapi' extension are now recognized and handled correctly again. See automake bug#11222. - Vala support work again for projects that contain some program built from '.vala' (and possibly '.c') sources and some other program built from '.c' sources *only*. See automake bug#11229. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.11.4: * Miscellaneous changes: - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no symbol index) modifiers as well as the "s" action, as the symbol index is created unconditionally by Microsoft lib. Also, the "q" (quick) action is now a synonym for "r" (replace). Also, the script has been ignoring the "v" (verbose) modifier already since Automake 1.11.3. - When the 'compile' script is used to wrap MSVC, it now accepts an optional space between the -I, -L and -l options and their respective arguments, for better POSIX compliance. - There is an initial, experimental support for automatic dependency tracking with tcc (the Tiny C Compiler). Its associated depmode is currently recognized as "icc" (but this and other details are likely to change in future versions). - Automatic dependency tracking now works also with the IBM XL C/C++ compilers, thanks to the new new depmode 'xlc'. Bugs fixed in 1.11.4: * Bugs introduced by 1.11.2: - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar) no longer cause spurious failures upon "make install". - The user can now instruct the 'uninstall-info' rule not to update the '${infodir}/dir' file by exporting the environment variable 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency with how the 'install-info' rule operates since automake 1.11.2. * Long-standing bugs: - It is now possible for a foo_SOURCES variable to hold Vala sources together with C header files, as well as with sources and headers for other supported languages (e.g., C++). Previously, only mixing C and Vala sources was supported. - If "aclocal --install" is used, and the first directory specified with '-I' is non-existent, aclocal will now create it before trying to copy files in it. - An empty declaration of a "foo_PRIMARY" no longer cause the generated install rules to create an empty $(foodir) directory; for example, if Makefile.am contains something like: pkglibexec_SCRIPTS = if FALSE pkglibexec_SCRIPTS += bar.sh endif the $(pkglibexec) directory will not be created upon "make install". ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.11.3: * Miscellaneous changes: - Automake's own build system is more silent by default, making use of the 'silent-rules' option. - The master copy of the 'gnupload' script is now maintained in gnulib, not in automake. - The 'missing' script no longer tries to wrap calls to 'tar'. - "make dist" no longer wraps 'tar' invocations with the 'missing' script. Similarly, the obsolescent variable '$(AMTAR)' (which you shouldn't be using BTW ;-) no longer invokes the 'missing' script to wrap tar, but simply invokes the 'tar' program itself. - "make dist" can now create lzip-compressed tarballs. - In the Automake info documentation, the Top node and the nodes about the invocation of the automake and aclocal programs have been renamed; now, calling "info automake" will open the Top node, while calling "info automake-invocation" and "info aclocal-invocation" will access the nodes about the invocation of respectively automake and aclocal. - Automake is now distributed as a gzip-compressed and an xz-compressed tarball. Previously, bzip2 was used instead of xz. - The last relics of Python 1.5 support have been removed from the AM_PATH_PYTHON macro. - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES and adds them to the normal list of dependencies, but without overwriting the foo_DEPENDENCIES variable, which is normally computed by automake. Bugs fixed in 1.11.3: * Bugs introduced by 1.11.2: - Automake now correctly recognizes the prefix/primary combination 'pkglibexec_SCRIPTS' as valid. - The parallel-tests harness no longer trips on sed implementations with stricter limits on the length of input lines (problem seen at least on Solaris 8). * Long-standing bugs: - The "deleted header file problem" for *.am files is avoided by stub rules. This allows 'make' to trigger a rerun of 'automake' also if some previously needed '.am' file has been removed. - The 'silent-rules' option now generates working makefiles even for the uncommon 'make' implementations that do not support the nested-variables extension to POSIX 2008. For such 'make' implementations, whether a build is silent is determined at configure time, and cannot be overridden at make time with "make V=0" or "make V=1". - Vala support now works better in VPATH setups. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.11.2: * Changes to aclocal: - The `--acdir' option is deprecated. Now you should use the new options `--automake-acdir' and `--system-acdir' instead. - The `ACLOCAL_PATH' environment variable is now interpreted as a colon-separated list of additional directories to search after the automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION) and before the system acdir (by default ${prefix}/share/aclocal). * Miscellaneous changes: - The Automake support for automatic de-ANSI-fication has been deprecated. It will probably be removed in the next major Automake release (1.12). - The `lzma' compression scheme and associated automake option `dist-lzma' is obsoleted by `xz' and `dist-xz' due to upstream changes. - You may adjust the compression options used in dist-xz and dist-bzip2. The default is now merely -e for xz, but still -9 for bzip; you may specify a different level via the XZ_OPT and BZIP2 envvars respectively. E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5" - The `compile' script now converts some options for MSVC for a better user experience. Similarly, the new `ar-lib' script wraps Microsoft lib. - The py-compile script now accepts empty arguments passed to the options `--destdir' and `--basedir', and complains about unrecognized options. Moreover, a non-option argument or a special `--' argument terminates the list of options. - A developer that needs to pass specific flags to configure at "make distcheck" time can now, and indeed is advised to, do so by defining the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS, instead of the old DISTCHECK_CONFIGURE_FLAGS. The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the user; still, the old Makefile.am files that used to define it will still continue to work as before. - New macro AM_PROG_AR that looks for an archiver and wraps it in the new 'ar-lib' auxiliary script if the selected archiver is Microsoft lib. This new macro is required for LIBRARIES and LTLIBRARIES when automake is run with -Wextra-portability and -Werror. - When using DejaGnu-based testsuites, the user can extend the `site.exp' file generated by automake-provided rules by defining the special make variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'. - The `install-info' rule can now be instructed not to create/update the `${infodir}/dir' file, by exporting the new environment variable `AM_UPDATE_INFO_DIR' to the value "no". Bugs fixed in 1.11.2: * Bugs introduced by 1.11: - The parallel-tests driver no longer produces erroneous results with Tru64/OSF 5.1 sh upon unreadable log files. - The `parallel-tests' test driver does not report spurious successes when used with concurrent FreeBSD make (e.g., "make check -j3"). - When the parallel-tests driver is in use, automake now explicitly rejects invalid entries and conditional contents in TEST_EXTENSIONS, instead of issuing confusing and apparently unrelated error messages (e.g., "non-POSIX variable name", "bad characters in variable name", or "redefinition of TEST_EXTENSIONS), or even, in some situations, silently producing broken `Makefile.in' files. - The `silent-rules' option now truly silences all compile rules, even when dependency tracking is disabled. Also, when `silent-rules' is not used, `make' output no longer contains spurious backslash-only lines, thus once again matching what Automake did before 1.11. - The AM_COND_IF macro also works if the shell expression for the conditional is no longer valid for the condition. * Long-standing bugs: - The order of Yacc and Lex flags is fixed to be consistent with other languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before $(LFLAGS), so that the user variables override the developer variables. - "make distcheck" now correctly complains also when "make uninstall" leaves one and only one file installed in $(prefix). - A "make uninstall" issued before a "make install", or after a mere "make install-data" or a mere "make install-exec" does not spuriously fail anymore. - Automake now warns about more primary/directory invalid combinations, such as "doc_LIBRARIES" or "pkglib_PROGRAMS". - Rules generated by Automake now try harder to not change any files when `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or Yacc source files and the rule to update config.h. - Several scripts and the parallel-tests testsuite driver now exit with the right exit status upon receiving a signal. - A per-Makefile.am setting of -Werror does not erroneously carry over to the handling of other Makefile.am files. - The code for automatic dependency tracking works around a Solaris make bug triggered by sources containing repeated slashes when the `subdir-objects' option was used. - The makedepend and hp depmodes now work better with VPATH builds. - Java sources specified with check_JAVA are no longer compiled for "make all", but only for "make check". - An usage like "java_JAVA = foo.java" will now cause Automake to warn and error out if `javadir' is undefined, instead of silently producing a broken Makefile.in. - aclocal and automake now honour the configure-time definitions of AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes. - The `install-info' recipe no longer tries to guess whether the `install-info' program is from Debian or from GNU, and adaptively change its behaviour; this has proven to be frail and easy to regress. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bugs fixed in 1.11.1: - Lots of minor bugfixes. * Bugs introduced by 1.11: - The `parallel-tests' test driver works around a GNU make 3.80 bug with trailing white space in the test list (`TESTS = foo $(EMPTY)'). * Long standing bugs: - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python' even if the `--prefix' argument pointed outside of a system directory. AM_PATH_PYTHON has been fixed to ignore the value returned from python's `get_python_lib' function if it points outside the configured prefix, unless the `--prefix' argument was either `/usr' or below `/System'. - The testsuite does not try to change the mode of `ltmain.sh' files from a Libtool installation (symlinked to test directories) any more. - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed tools are preferred in a cross-compile setup. - The distribution is tarred up with mode 755 now by the `dist*' targets. This fixes a race condition where untrusted users could modify files in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel build directory was world-searchable. This is CVE-2009-4029. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.11: * Version requirements: - Autoconf 2.62 or greater is required. * Changes to aclocal: - The autoconf version check implemented by aclocal in aclocal.m4 (and new in Automake 1.10) is degraded to a warning. This helps in the common case where the Autoconf versions used are compatible. * Changes to automake: - The automake program can run multiple threads for creating most Makefile.in files concurrently, if at least Perl 5.7.2 is available with interpreter-based threads enabled. Set the environment variable AUTOMAKE_JOBS to the maximum number of threads to use, in order to enable this experimental feature. * Changes to Libtool support: - Libtool generic flags are now passed to the install and uninstall modes as well. - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as config.lt is removed correctly now. * Languages changes: - subdir-object mode works now with Fortran (F77, FC, preprocessed Fortran, and Ratfor). - For files with extension .f90, .f95, .f03, or .f08, the flag $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules. - Files with extension .sx are also treated as preprocessed assembler. - The default source file extension (.c) can be overridden with AM_DEFAULT_SOURCE_EXT now. - Python 3.0 is supported now, Python releases prior to 2.0 are no longer supported. - AM_PATH_PYTHON honors python's idea about the site directory. - There is initial support for the Vala programming language, when using Vala 0.7.0 or later. * Miscellaneous changes: - Automake development is done in a git repository on Savannah now, see https://git.sv.gnu.org/gitweb/?p=automake.git A read-only CVS mirror is provided at cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \ checkout -d automake HEAD - "make dist" can now create xz-compressed tarballs, as well as (deprecated?) lzma-compressed tarballs. - `automake --add-missing' will by default install the GPLv3 file as COPYING if it is missing. It will also warn that the license file should be added to source control. Note that Automake will never overwrite an existing COPYING file, even when the `--force-missing' option is used. - The manual is now distributed under the terms of the GNU FDL 1.3. - Automake ships and installs man pages for automake and aclocal now. - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'. - install-sh supports -C, which does not update the installed file (and its time stamps) if the contents did not change. - The `gnupload' script has been revamped. - The `depcomp' and `compile' scripts now work with MSVC under MSYS. - The targets `install' and `uninstall' are more efficient now, in that for example multiple files from one Automake variable such as `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install') invocation if they do not have to be renamed. Both install and uninstall may sometimes enter (`cd' into) the target installation directory now, when no build-local scripts are used. Both install and uninstall do not fail anymore but do nothing if an installation directory variable like `bindir' is set to the empty string. For built-in rules, `make install' now fails reliably if installation of a file failed. Conversely, `make uninstall' even succeeds when issued multiple times. These changes may need some adjustments from users: For example, some `install' programs refuse to install multiple copies of the same file in one invocation, so you may need to remove duplicate entries from file lists. Also, within one set of files, say, nobase_data_DATA, the order of installation may be changed, or even unstable among different hosts, due to the use of associative arrays in awk. The increased use of awk matches a similar move in Autoconf to provide for better scaling. Further, most undocumented per-rule install command variables such as binSCRIPT_INSTALL have been removed because they are not needed any more. Packages which use them should be using the appropriate one of INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT} counterpart, depending on the type of files and the need for automatic target directory creation. - The "deleted header file problem" for *.m4 files is avoided by stub rules. This allows `make' to trigger a rerun of `aclocal' also if some previously needed macro file has been removed. - Rebuild rules now also work for a removed `subdir/Makefile.in' in an otherwise up to date tree. - The `color-tests' option causes colored test result output on terminals. - The `parallel-tests' option enables a new test driver that allows for parallel test execution, inter-test dependencies, lazy test execution for unit-testing, re-testing only failed tests, and formatted result output as RST (reStructuredText) and HTML. Enabling this option may require some changes to your test suite setup; see the manual for details. - The `silent-rules' option enables Linux kernel-style silent build output. This option requires the widely supported but non-POSIX `make' feature of recursive variable expansion, so do not use it if your package needs to build with `make' implementations that do not support it. To enable less verbose build output, the developer has to use the Automake option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES' macro. The user may then set the default verbosity by passing the `--enable-silent-rules' option to `configure'. At `make' run time, this default may be overridden using `make V=0' for less verbose, and `make V=1' for backward-compatible verbose output. - New prefix `notrans_' for manpages which should not be transformed by --program-transform. - New macro AM_COND_IF for conditional evaluation and conditional config files. - For AC_CONFIG_LINKS, if source and destination are equal, do not remove the file in a non-VPATH build. Such setups work with Autoconf 2.62 or newer. - AM_MAINTAINER_MODE now allows for an optional argument specifying the default setting. - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables, useful especially for multi-line values. - Automake's early configure-time sanity check now diagnoses an unsafe absolute source directory name and makes configure fail. - The Automake macros and rules cope better with whitespace in the current directory name, as long as the relative path to `configure' does not contain whitespace. To this end, the values of `$(MISSING)' and `$(install_sh)' may contain suitable quoting, and their expansion might need `eval'uation if used outside of a makefile. These undocumented variables may be used in several documented macros such as $(AUTOCONF) or $(MAKEINFO). Bugs fixed in 1.11: * Long-standing bugs: - Fix aix dependency tracking for libtool objects. - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to unnecessary use of the `compile' script. - For nobase_*_LTLIBRARIES with nonempty directory components, the correct `-rpath' argument is used now. - `config.status --file=Makefile depfiles' now also works with the extra quoting used internally by Autoconf 2.62 and newer (it used to work only without the `--file=' bit). - The `missing' script works better with versioned tool names. - Semantics for `missing help2man' have been revamped: Previously, if `help2man' was not present, `missing help2man' would have the following semantics: if some man page was out of date but present, then a warning would be printed, but the exit status was 0. If the man page was not present at all, then `missing' would create a replacement man page containing an error message, and exit with a status of 2. This does not play well with `make': the next run will see this particular man page as being up to date, and will only error out on the next generated man page, if any; repeat until all pages are done. This was not desirable. These are the new semantics: if some man page is not present, and help2man is not either, then `missing' will warn and generate the replacement page containing the error message, but exit successfully. However, `make dist' will ensure that no such bogus man pages are packaged into a tarball. - Targets provided by automake behave better with `make -n', in that they take care not to create files. - `config.status Makefile... depfiles' works fine again in the presence of disabled dependency tracking. - The default no-op recursive rules for these targets also work with BSD make now: html, install-html, install-dvi, install-pdf, install-pdf, install-info. - `make distcheck' works also when both a directory and some file below it have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES. - Texinfo dvi, ps, pdf, and html output files are not removed upon `make mostlyclean' any more; only the LaTeX by-products are. - Renamed objects also work with the `subdir-objects' option and source file languages which Automake does not know itself. - `automake' now correctly complains about variable assignments which are preceded by a comment, extend over multiple lines with backslash-escaped newlines, and end in a comment sign. Previous versions would silently and wrongly ignore such assignments completely. * Bugs introduced by 1.10: - Fix output of dummy dependency files in presence of post-processed Makefile.in's again, but also cope with long lines. - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS that have been declared as programs in the same Makefile. This is for consistency with the analogous change to TESTS in 1.10. - Fix order of standard includes to again be `-I. -I$(srcdir)', followed by directories containing config headers. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.10: * Version requirements: - Autoconf 2.60 or greater is required. - Perl 5.6 or greater is required. * Changes to aclocal: - aclocal now also supports -Wmumble and -Wno-mumble options. - `dirlist' entries (for the aclocal search path) may use shell wildcards such as `*', `?', or `[...]'. - aclocal supports an --install option that will cause system-wide third-party macros to be installed in the local directory specified with the first -I flag. This option also uses #serial lines in M4 files to upgrade local macros. The new aclocal options --dry-run and --diff help to review changes before they are installed. - aclocal now outputs an autoconf version check in aclocal.m4 in projects using automake. For a few years, automake and aclocal have been calling autoconf (or its underlying engine autom4te) to accurately retrieve the data they need from configure.ac and its siblings. Doing so can only work if all autotools use the same version of autoconf. For instance a Makefile.in generated by automake for one version of autoconf may stop working if configure is regenerated with another version of autoconf, and vice versa. This new version check ensures that the whole build system has been generated using the same autoconf version. * Support for new Autoconf macros: - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported. - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified, $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used in different directories. However, only one instance of such a library objects directory is supported. * Change to Libtool support: - Libtool generic flags (those that go before the --mode=MODE option) can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS. * Yacc and Lex changes: - The rebuild rules for distributed Yacc and Lex output will avoid overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode is not enabled. - ylwrap is now always used for lex and yacc source files, regardless of whether there is more than one source per directory. * Languages changes: - Preprocessed assembler (*.S) compilation now honors CPPFLAGS, AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency tracking, unlike non-preprocessed assembler (*.s). - subdir-object mode works now with Assembler. Automake assumes that the compiler understands `-c -o'. - Preprocessed assembler (*.S) compilation now also honors $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES). - Improved support for Objective C: - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking. - A new section of the manual documents the support. - New support for Unified Parallel C: - AM_PROG_UPC looks for a UPC compiler. - A new section of the manual documents the support. - Per-target flags are now correctly handled in link rules. For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly preferred AM_CFLAGS over maude_CFLAGS while linking, and they used both AM_LDFLAGS and maude_LDFLAGS on the same link command. The fix for compiler flags (i.e., using maude_CFLAGS instead of AM_CFLAGS) should not hurt any package since that is how _CFLAGS is expected to work (and actually works during compilation). However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than "in addition to" breaks backward compatibility with older versions. If your package used both variables, as in AM_LDFLAGS = common flags bin_PROGRAMS = a b c a_LDFLAGS = more flags ... and assumed *_LDFLAGS would sum up, you should rewrite it as AM_LDFLAGS = common flags bin_PROGRAMS = a b c a_LDFLAGS = $(AM_LDFLAGS) more flags ... This new behavior of *_LDFLAGS is more coherent with other per-target variables, and the way *_LDFLAGS variables were considered internally. * New installation targets: - New targets mandated by GNU Coding Standards: install-dvi install-html install-ps install-pdf By default they will only install Texinfo manuals. You can customize them with *-local variants: install-dvi-local install-html-local install-ps-local install-pdf-local - The undocumented recursive target `uninstall-info' no longer exists. (`uninstall' is in charge of removing all possible documentation flavors, including optional formats such as dvi, ps, or info even when `no-installinfo' is used.) * Miscellaneous changes: - Automake no longer complains if input files for AC_CONFIG_FILES are specified using shell variables. - clean, distribution, or rebuild rules are normally disabled for inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and AC_CONFIG_LINK specified using shell variables. However, if these variables are used as ${VAR}, and AC_SUBSTed, then Automake will be able to output rules anyway. (See the Automake documentation for AC_CONFIG_FILES.) - $(EXEEXT) is automatically appended to filenames of TESTS that have been declared as programs in the same Makefile. This is mostly useful when some check_PROGRAMS are listed in TESTS. - `-Wportability' has finally been turned on by default for `gnu' and `gnits' strictness. This means, automake will complain about %-rules or $(GNU Make functions) unless you switch to `foreign' strictness or use `-Wno-portability'. - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses $(MKDIR_P) instead of $(mkdir_p) to create directories. The $(mkdir_p) variable is still defined (to the same value as $(MKDIR_P)) but should be considered obsolete. If you are using $(mkdir_p) in some of your rules, please plan to update them to $(MKDIR_P) at some point. - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete. They still work in this release, but may be withdrawn in a future one. - Inline compilation rules for gcc3-style dependency tracking are more readable. - Automake installs a "Hello World!" example package in $(docdir). This example is used throughout the new "Autotools Introduction" chapter of the manual. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.9: * Makefile.in bloat reduction: - Inference rules are used to compile sources in subdirectories when the `subdir-objects' option is used and no per-target flags are used. This should reduce the size of some projects a lot, because Automake used to output an explicit rule for each such object in the past. - Automake no longer outputs three rules (.o, .obj, .lo) for each object that must be built with explicit rules. It just outputs the rules required to build the kind of object considered: either the two .o and .obj rules for usual objects, or the .lo rule for libtool objects. * Change to Libtool support: - Libtool tags are used with libtool versions that support them. (I.e., with Libtool 1.5 or greater.) - Automake is now able to handle setups where a libtool library is conditionally installed in different directories, as in if COND lib_LTLIBRARIES = liba.la else pkglib_LTLIBRARIES = liba.la endif liba_la_SOURCES = ... * Changes to aclocal: - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are really evaluated, before it decides to include them in aclocal.m4. This solves nasty problems with conditional redefinitions of Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous *.m4 files to be included in any project using these macros. (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the most famous instance of this bug.) - Do not complain about missing conditionally AC_REQUIREd macros that are not actually used. In 1.8.x aclocal would correctly determine which of these macros were really needed (and include only these in the package); unfortunately it would also require all of them to be present in order to run. This created situations were aclocal would not work on a tarball distributing all the macros it uses. For instance running aclocal on a project containing only the subset of the Gettext macros in use by the project did not work, because gettext conditionally requires other macros. * Portability improvements: - Tar format can be chosen with the new options tar-v7, tar-ustar, and tar-pax. The new option filename-length-max=99 helps diagnosing filenames that are too long for tar-v7. (PR/414) - Variables augmented with `+=' are now automatically flattened (i.e., trailing backslashes removed) and then wrapped around 80 columns (adding trailing backslashes). In previous versions, a long series of VAR += value1 VAR += value2 VAR += value3 ... would result in a single-line definition of VAR that could possibly exceed the maximum line length of some make implementations. Non-augmented variables are still output as they are defined in the Makefile.am. * Miscellaneous: - Support Fortran 90/95 with the new "fc" and "ppfc" languages. Works the same as the old Fortran 77 implementation; just replace F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS). Requires a version of autoconf which provides AC_PROG_FC (>=2.59). - Support for conditional _LISP. - Support for conditional -hook and -local rules (PR/428). - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49) - Automake will not write any Makefile.ins after the first error it encounters. The previous Makefile.ins (if any) will be left in place. (Warnings will not prevent output, but remember they can be turned into errors with -Werror.) - The restriction that SUBDIRS must contain direct children is gone. Do not abuse. - The manual tells more about SUBDIRS vs. DIST_SUBDIRS. It also gives an example of nested packages using AC_CONFIG_SUBDIRS. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bugs fixed in 1.8.5: * Long-standing bugs: - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used so that `make distclean' and `make maintainer-clean' can work. - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined. - Fix many rules to please FreeBSD make, which runs commands with `sh -e'. - Polish diagnostic when no input file is found. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bugs fixed in 1.8.4: * Long-standing bugs: - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been overridden by the user. - Honor PATH_SEPARATOR in various places of the Automake package, for the sake of OS/2. - Adjust dependency tracking mode detection to ICC 8.0's new output. (PR/416) - Fix install-sh so it can install the `mv' binary... using `mv'. - Fix tru64 dependency tracking for libtool objects. - Work around Exuberant Ctags when creating a TAGS files in a directory without files to scan but with subdirectories to include. * Bugs introduced by 1.8: - Fix an "internal error" when @LIBOBJS@ is used in a variable that is not defined in the same conditions as the _LDADD that uses it. - Do not warn when JAVAROOT is overridden, this is legitimate. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bugs fixed in 1.8.3: * Long-standing bugs: - Quote filenames in installation rules, in case $DESTDIR, $prefix, or any of the other *dir variables contain a space. Please note that Automake does not and cannot support spaces in filenames that are involved during the build. This change affects only installation paths, so that `make install' does not bomb out in packages configured with ./configure --prefix '/c/Program Files' - Fix the depfiles output so it works with GNU sed (<4.1) even when POSIXLY_CORRECT is set. - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable since Autoconf 2.54, which defines LIBOBJS itself. - Fix a potential (but unlikely) race condition in parallel elisp builds. (Introduced in 1.7.3.) - Do not assume that users override _DEPENDENCIES in all conditions where Automake will try to define them. - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir. Solaris 8's `mkdir -p' is not thread-safe and can break parallel builds. This fix also affects the $(mkdir_p) variable defined since Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise. - Secure temporary directory creation in `make distcheck'. (PR/413) - Do not generate two build rules for `parser.h' when the parser appears in two different conditionals. - Work around a Solaris 8 /bin/sh bug in the test for dependency checking. Usually ./configure will not pick this shell; so this fix only helps cases where the shell is forced to /bin/sh. * Bugs introduced by 1.8: - In some situations (hand-written `m4_include's), aclocal would call the `File::Spec->rel2abs' method, which was only introduced in Perl 5.6. This new version reestablish support Perl 5.005. It is likely that the next major Automake releases will require at least Perl 5.6. Consider upgrading your development environment if you are still using the five-year-old Perl 5.005. - Automake would sometimes fail to define rules for targets listed in variables defined in multiple conditions. For instance on if C1 bin_PROGRAMS = a else bin_PROGRAMS = b endif it would define only the `a.$(OBJEXT): a.c' rule and omit the `b.$(OBJEXT): b.c' rule. * New sections in manual: - Third-Party Makefiles: how to interface third party Makefiles. - Upgrading: upgrading packages to newer Automake versions. - Multiple Outputs: handling tools that produce many outputs. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bug fixed in 1.8.2: * A (well known) portability bug slipped in the changes made to install-sh in Automake 1.8.1. The broken install-sh would refuse to install anything on Tru64. * Fix install rules for conditionally built python files. (This never really worked.) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bug fixed in 1.8.1: * Bugs introduced by 1.8: - Fix Config.pm import error with old Perl versions (at least 5.005_03). One symptom is that aclocal could not find its macro directory. - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories created by `make install' are always world readable, even if the installer happens to have an overly restrictive umask (e.g. 077). This was a mistake and has been reverted. There are at least two reasons why we must not use `-m 0755': - it causes special bits like SGID to be ignored, - it may be too restrictive (some setups expect 775 directories). - Fix aclocal to honor definitions located in files which have been m4_included manually. aclocal 1.8 had been updated to check m4_included files for new requirements, but forgot that these m4_included files can also provide new definitions. Note that if you have such a setup, we recommend you get rid of it. In the past, there was a reason to m4_include files manually: aclocal used to duplicate entire M4 files into aclocal.m4, even files that were distributed. Some packages were therefore m4_including the distributed file directly, and playing some tricks to ensure aclocal would not copy that file to aclocal.m4, in order to limit the amount of duplication. Since aclocal 1.8.x will precisely output m4_includes for local M4 files, we recommend that you clean up your setup, removing all manual m4_includes and letting aclocal output them. - Output detailed menus in the Info version if the Automake manual, so that Emacs can locate the indexes. - configure.ac and configure were listed twice in DIST_COMMON (an internal variable where Automake lists configury files to distribute). This was harmless, but unaesthetic. - Use `chmod a-w' instead of `chmod -w' as the latter honors umask. This was an issue only in the Automake package itself, not in its output. - Automake assumed that all AC_CONFIG_LINKS arguments had the form DEST:SRC. This was wrong, as some packages do AC_CONFIG_LINKS($computedlinks). This version no longer abort in that situation. - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one argument. This caused two kinds of failures: - Rules installing data in a conditionally defined directory failed when that directory was undefined. In this case no argument was supplied. - `make installdirs' failed, because several directories were passed to $(mkdir_p). This was an issue only on platform were $(mkdir_p) is implemented with `install-sh -d'. $(mkdir_p) as been changed to accept 0 or more arguments, as mkinstalldirs did. * Long-standing bugs: - Fix an unexpected diagnostic occurring when users attempt to override some internal variables that Automake appends to. - aclocal now scans configure.ac for macro definitions (PR/319). - Fix a portability issue with OSF1/Tru64 Make. If a directory distributes files which are outside itself (this usually occurs when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files from a parent package), then `make distcheck' fails due to an optimization performed by OSF1/Tru64 Make in its VPATH handling. (tests/subpkg2.test failure) - Fix another portability issue with Sun and OSF1/Tru64 Make. In a VPATH-build configuration, `make install' would install nobase_ files to wrong locations. - Fix a Perl `uninitialized value' diagnostic occurring when automake complains that a Texinfo file does not have a @setfilename statement. - Erase config.status.lineno during `make distclean'. This file can be created by config.status. Automake already knew about configure.lineno, but forgot config.status.lineno. - Distribute all files, even those which are built and installed conditionally. This change affects files listed in conditionally defined *_HEADERS and *_PYTHON variable (unless they are nodist_*) as well as those listed in conditionally defined dist_*_DATA, dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables. - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it doesn't conform to POSIX. - Normalize help strings for configure variables and options added by Automake macros. * Anticipation: - Check for python2.4 in AM_PATH_PYTHON. * Spurious failures in test suite: - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test, tests/ltconv.test: fix failures with CVS Libtool. - tests/aclocal6.test: fix failure if autom4te.cache is disabled. - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test: fix failures with old Texinfo versions. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.8: * Meta-News - The NEWS file is more verbose. * Requirements - Autoconf 2.58 or greater is required. * New features - Default source file names in the absence of a _SOURCES declaration are made by removing any target extension before appending `.c', so to make the libtool module `foo.la' from `foo.c', you only need to do this: lib_LTLIBRARIES = foo.la foo_la_LDFLAGS = -module For backward compatibility, foo_la.c will be used instead of foo.c if this file exists or is the explicit target of a rule. However -Wobsolete will warn about this deprecated naming. - AR's `cru' flags are now set in a global ARFLAGS variable instead of being hard-coded in each $(AR) invocation, so they can be substituted from configure.ac. This has been requested by people dealing with non-POSIX ar implementations. - New warning option: -Woverride. This will warn about any user target or variable definitions which override Automake definitions. - Texinfo rules back up and restore info files when makeinfo fails. - Texinfo rules now support the `html' target. Running this requires Texinfo 4.0 or greater. `html' is a new recursive target, so if your package mixes hand-crafted `Makefile.in's with Automake-generated `Makefile.in's, you should adjust the former to support (or ignore) this target so that `make html' recurses successfully. If you had a custom `html' rule in your `Makefile.am', it's better to rename it as `html-local', otherwise your rule will override Automake's new rule (you can check that by running `automake -Woverride') and that will stop the recursion to subdirectories. Last but not least, this `html' rule is declared PHONY, even when overridden. Fortunately, it appears that few packages use a non-PHONY `html' rule. - Any file which is m4_included from configure.ac will appear as a configure and Makefile.in dependency, and will be automatically distributed. - The rules for rebuilding Makefiles and Makefile.ins will now rebuild all Makefiles and all Makefile.ins at once when one of configure's dependencies has changed. This is considerably faster than previous implementations, where config.status and automake were run separately in each directory (this still happens when you change a Makefile.am locally, without touching configure.ac or friends). Doing this also solves a longstanding issue: these rebuild rules failed to work when adding new directories to the tree, forcing you to run automake manually. - For similar reasons, the rules to rebuild configure, config.status, and aclocal.m4 are now defined in all directories. Note that if you were using the CONFIG_STATUS_DEPENDENCIES and CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you should better define them in all directories. This is easily done using an AC_SUBST (make sure you prefix these dependencies with $(top_srcdir) since this variable will appear at different levels of the build tree). - aclocal will now use `m4_include' instead of copying local m4 files into aclocal.m4. (Local m4 files are those you ship with your project, other files will be copied as usual.) Because m4_included files are automatically distributed, it means for most projects there is no point in EXTRA_DISTing the list of m4 files which are used. (You can probably get rid of m4/Makefile.am if you had one.) - aclocal will avoid touching aclocal.m4 when possible, so that Autom4te's cache isn't needlessly invalidated. This behavior can be switched off with the new `--force' option. - aclocal now uses Autoconf's --trace to detect macros which are actually used and will no longer include unused macros simply because they where mentioned. This was often the case for macros called conditionally. - New options no-dist and no-dist-gzip. - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs, py-compile, and ylwrap, now all understand --version and --help. - Automake will now recognize AC_CONFIG_LINKS so far as removing created links as part of the distclean target and including source files in distributions. - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND argument. The latter can be used to override the default behavior (which is to abort). - Automake will exit with $? = 63 on version mismatch. (So does Autoconf 2.58) missing knows this, and in this case it will emulate the tools as if they were absent. Because older versions of Automake and Autoconf did not use this exit code, this change will only be useful in projects generated with future versions of these tools. - When using AC_CONFIG_FILES with multiple input files, Automake generates the first ".in" input file for which a ".am" exists. (Former versions would try to use only the first input file.) - lisp_DATA is now allowed. If you are using the empty ELCFILES idiom to disable byte-compilation of lisp_LISP files, it is recommended that you switch to using lisp_DATA. Note that this is not strictly equivalent: lisp_DATA will install elisp files even if emacs is not installed, while *_LISP do not install anything unless emacs is found. - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is available. This selection is achieved through the Makefile variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or `$(install_sh) -m 0755 -d'. * Obsolete features - Because `mkdir -p' is available on most platforms, and we can use `install-sh -d' when it is not, the use of the mkinstalldirs script is being phased out. `automake --add-missing' no longer installs it, and if you remove mkinstalldirs from your package, automake will define $(mkinstalldirs) as an alias for $(mkdir_p). Gettext 0.12.1 still requires mkinstalldirs. Fortunately gettextize and autopoint will install it when needed. Automake will continue to define the $(mkinstalldirs) and to distribute mkinstalldirs when this script is in the source tree. - AM_PROG_CC_STDC is now empty. The content of this macro was merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you should adjust it to use $ac_cv_prog_cc_stdc instead. (This renaming should be safe, even if you have to support several, versions of Automake, because AC_PROG_CC defines this variable since Autoconf 2.54.) - Some users where using the undocumented ACLOCAL_M4_SOURCES variable to override the aclocal.m4 dependencies computed (inaccurately) by older versions of Automake. Because Automake now tracks configure's m4 dependencies accurately (see m4_include above), the use of ACLOCAL_M4_SOURCES should be considered obsolete and will be flagged as such when running `automake -Wobsolete'. * Bug fixes - Defining programs conditionally using Automake conditionals no longer leads to a combinatorial explosion. The following construct used to be troublesome when used with dozens of conditions. bin_PROGRAMS = a if COND1 bin_PROGRAMS += a1 endif if COND2 bin_PROGRAMS += a2 endif if COND3 bin_PROGRAMS += a3 endif ... Likewise for _SOURCES, _LDADD, and _LIBADD variables. - Due to implementation constraints, previous versions of Automake proscribed multiple conditional definitions of some variables like bin_PROGRAMS: if COND1 bin_PROGRAMS = a1 endif if COND2 bin_PROGRAMS = a2 endif All _PROGRAMS, _LDADD, and _LIBADD variables were affected. This restriction has been lifted, and these variables now support multiple conditional definitions as do other variables. - Cleanup the definitions of $(distdir) and $(top_distdir). $(top_distdir) now points to the root of the distribution directory created during `make dist', as it did in Automake 1.4, not to the root of the build tree as it did in intervening versions. Furthermore these two variables are now only defined in the top level Makefile, and passed to sub-directories when running `make dist'. - The --no-force option now correctly checks the Makefile.in's dependencies before deciding not to update it. - Do not assume that make files are called Makefile in cleaning rules. - Update .info files in the source tree, not in the build tree. This is what the GNU Coding Standard recommend. Only Automake 1.7.x used to update these files in the build tree (previous versions did it in the source tree too), and it caused several problems, varying from mere annoyance to portability issues. - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten when --add-missing and --force-missing are used. For backward compatibility --add-missing will continue to install COPYING (in `gnu' strictness) when none of these three files exist, but this use is deprecated: you should better choose a license yourself and install it once for all in your source tree (and in your code management system). - Fix ylwrap so that it does not overwrite header files that haven't changed, as the inline rule already does. - User-defined rules override automake-defined rules for the same targets, even when rules do not have commands. This is not new (and was documented), however some of the automake-generated rules have escaped this principle in former Automake versions. Rules for the following targets are affected by this fix: clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am, info, info-am, install-data-am, install-exec-am, install-info, install-info-am, install-man, installcheck-am, maintainer-clean, maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am, ps, ps-am, uninstall-am, uninstall-info, uninstall-man Practically it means that an attempt to supplement the dependencies of some target, as in clean: my-clean-rule will now *silently override* the automake definition of the rule for this target. Running `automake -Woverride' will diagnose all such overriding definitions. It should be noted that almost all of these targets support a *-local variant that is meant to supplement the automake-defined rule (See node `Extending' in the manual). The above rule should be rewritten as clean-local: my-clean-rule These *-local targets have been documented since at least Automake 1.2, so you should not fear the change if you have to support multiple automake versions. * Miscellaneous - The Automake manual is now distributed under the terms of the GNU FDL. - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined. - core dumps are no longer removed by the cleaning rules. There are at least three reasons for this: 1. These files should not be created by any build step, so their removal do not fit any of the cleaning rules. Actually, they may be precious to the developer. 2. If such file is created during a build, then it's clearly a bug Automake should not hide. Not removing the file will cause `make distcheck' to complain about its presence. 3. Operating systems have different naming conventions for core dump files. A core file on one system might be a completely legitimate data file on another system. - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer defined by Automake. This means that any definition in the environment will be used, unless overridden in the Makefile.am or on the command line. The old behavior, where these variables were defined empty in each Makefile, can be obtained by AC_SUBSTing or AC_ARG_VARing each variable from configure.ac. - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now documented. (The is not a new feature, these variables have been there since at least Automake 1.4.) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bugs fixed in 1.7.9: * Fix install-strip to work with nobase_ binaries. * Fix renaming of #line directives in ylwrap. * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.) Bugs fixed in 1.7.8: * Remove spurious blank lines in cleaning rules introduced in 1.7.7. * Fix detection of Debian's install-info, broken since version 1.5. (Debian bug #213524). * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking) This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions. Bugs fixed in 1.7.7: * The implementation of automake's --no-force option is unreliable, so this option is ignored in this version. A real fix will appear in Automake 1.8. (Debian Bug #206299) * AM_PATH_PYTHON: really check the whole list of interpreters if no argument is given. (PR/399) * Do not warn about leading `_' in variable names, even with -Wportability. * Support user redefinitions of TEXINFO_TEX. * depcomp: support AIX Compiler version 6. * Fix missing rebuilds during `make dist' with BSD make. (Could produce tarballs containing out-of-date files.) * Resurrect multilib support. * Noteworthy manual updates: - Extending aclocal: how to write m4 macros that won't trigger warnings with Automake 1.8. - A Shared Library: Rewrite and split into subsections. Bugs fixed in 1.7.6: * Fix depcomp's icc mode for ICC 7.1. * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments. * Fix maintainer-clean's removal of autom4te.cache in VPATH builds. * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1. * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS. * Remove Latin-1 characters from elisp-comp. * Update the manual's @dircategory to match the Free Software Directory.

Bugs fixed in 1.7.4: * Tweak the TAGS rule to support Exuberant Ctags (in addition to the Emacs implementation) * Fix output of aclocal.m4 dependencies in subdirectories. * Use `mv -f' instead of `mv' in fastdep rules. * Upgrade mdate-sh to work on OS/2. * Don't byte-compile elisp files when ELCFILES is set empty. (this documented feature was broken by 1.7.3) * Diagnose trailing backslashes on last line of Makefile.am. * Diagnose whitespace following trailing backslashes. * Multiple tests are now correctly supported in DEJATOOL. (PR/388) * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot]) Makefiles. (PR/389) * `make install' will build `BUILT_SOURCES' first. * Minor documentation fixes. Bugs fixed in 1.7.3: * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS). * Query distutils for `pythondir' and `pythonexecdir', instead of using an hardcoded path. This should allow builds on 64-bit distributions that usually use lib64/ instead of lib/. * AM_PATH_PYTHON will also search for python2.3. * elisp files are now built all at once instead of one by one. Besides incurring a speed-up, this is required to support interdependent elisp files. * Support for DJGPP: - `make distcheck' will now work in `_inst/' and `_build' instead of `=inst/' and `=build/' - use `_dirstamp' when the file-system doesn't support `.dirstamp' - install/uninstall `*.i[0-9][0-9]'-style info files - more changes that affect only the Automake package (not its output) * Fix some incompatibilities with upcoming perl-5.10. * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining PACKAGE and VERSION. * depcomp fixes: - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this is troublesome with gcc and Solaris compilers. (PR/385) - makedepend mode: work with Libtool. (PR/385 too) - support for ICC. * better support for unusual gettext setups, such as multiple po/ directories (PR/381): - Flag missing po/ and intl/ directories as warnings, not errors. - Disable these warnings if po/ does not exist. * Noteworthy manual updates: - New FAQ chapter. - Document how AC_CONFIG_AUX_DIR interacts with missing files. (Debian Bug #39542) - Document `AM_YFLAGS = -d'. (PR/382) Bugs fixed in 1.7.2: * Fix installation and uninstallation of Info files built in subdirectories. * Do not run `./configure --with-included-gettext' during `make distcheck' if AM_GNU_GETTEXT([external]) is used. * Correctly uninstall renamed man pages. * Do not strip escaped newline in variables defined in one condition and augmented in another condition. * Fix ansi2knr rules for LIBOBJS sources. * Clean all known Texinfo index files, not only those which appear to be used, because we cannot know which indexes are used in included files. (PR/375, Debian Bug #168671) * Honor only the first @setfilename seen in a Texinfo file. * Treat "required file X not found" diagnostics as errors (exit status 1). * Don't complain that a required file is not found when it is a Makefile target. (PR/357) * Don't use single suffix inference rules when building `.info'-less Info files, for the sake of Solaris make. * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359) * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371) * Warn about multiple inference rules when -Wportability is used. (PR/372) * Fix building of deansified files from subdirectories. (PR/370) * Add missing `fi' in the .c->.obj rules. * Improve install-sh to work even when names contain spaces or certain (but not all) shell metachars. * Fix the following spurious failures in the test suite: depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test * Noteworthy manual updates: - Augment the section about BUILT_SOURCES. - Mention that AM_PROG_CC_STDC is a relic that is better avoided today. Bugs fixed in 1.7.1: * Honor `ansi2knr' for files built in subdirectories, or using per-targets flags. * Aclocal should now recognize macro names containing parentheses, e.g. AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]). * Erase *.sum and *.log files created by DejaGnu, during `make distclean'. (Debian Bug#153697) * Install Python files even if they were built. (PR/369) * Have stamp-vti dependent upon configure instead of configure.ac, as the version might not be defined in the latter. (PR/358) * Reorder arguments passed to a couple of commands, so things works when POSIXLY_CORRECT=1. * Fix a regex that can cause Perl to segfault on large input. (Debian Bug#162583) * Fix distribution of packages that have some sources defined conditionally, as in the `Conditional compilation using Automake conditionals' example of the manual. * Fix spurious test suite failures on IRIX. * Don't report a required variable as undefined if it has been defined conditionally for the "right" conditions. * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case `make distcheck' fails. * Fix distribution of included Makefile fragment, so we don't create spurious directories in the distribution. (PR/366) * Don't complain that a target lacks `.$(EXEEXT)' when it has it. New in 1.7: * Autoconf 2.54 is required. * `aclocal' and `automake' will no longer warn about obsolete configure macros. This is done by `autoconf -Wobsolete'. * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS, and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade `configure.ac' for you. * Support for per-program and per-library `_CPPFLAGS'. * New `ctags' target (builds CTAGS files). * Support for -Wmumble and -Wno-mumble, where mumble is a warning category (see `automake --help' or the manual for a list of them). * Honor the WARNINGS environment variable. * Omit the call to depcomp when using gcc3: call the compiler directly. * A new option, std-options, tests that programs support --help and --version when `make installcheck' is run. This is enabled by --gnits. * Texinfo rules now support the `ps' and `pdf' targets. * Info files are now created in the build directory, not the source directory. * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1 or greater). * `make distcheck' will enforce DESTDIR support by attempting a DESTDIR install. * `+=' can be used in conditionals, even if the augmented variable was defined for another condition. * Makefile fragments (inserted with `include') are always distributed. * Use Autoconf's --trace interface to inspect configure.ac and get a more accurate view of it. * Add support for extending aclocal's default macro search path using a `dirlist' file within the aclocal directory. * automake --output-dir is deprecated. * The part of the distcheck target that checks whether uninstall actually removes all installed files has been moved in a separate target, distuninstallcheck, so it can be overridden easily. * Many bug fixes. New in 1.6.3: * Support for AM_INIT_GETTEXT([external]) * Bug fixes, including: - Fix Automake's own `make install' so it works even if `ln' doesn't. - nobase_ programs and scripts honor --program-transform correctly. - Erase configure.lineno during `make distclean'. - Erase YACC and LEX outputs during `make maintainer-clean'. New in 1.6.2: * Many bug fixes, including: - Requiring the current version works. - Fix "$@" portability issues (for Zsh). - Fix output of dummy dependency files in presence of post-processed Makefile.in's. - Don't compute dependencies in background to avoid races with libtool. - Fix handling of _OBJECTS variables for targets sharing source variables. - Check dependency mode for Java when AM_PROG_GCJ is used. New in 1.6.1: * automake --output-dir is deprecated * Many bug fixes, including: - Don't choke on AM_LDFLAGS definitions. - Clean libtool objects from subdirectories. - Allow configure variables with reserved suffix and unknown prefix (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target). - Fix the definition of AUTOMAKE and ACLOCAL in configure. New in 1.6: * Autoconf 2.52 is required. * automake no longer run libtoolize. This is the job of autoreconf (from GNU Autoconf). * `dist' generates all the archive flavors, as did `dist-all'. * `dist-gzip' generates the Gzip tar file only. * Combining Automake Makefile conditionals no longer lead to a combinatorial explosion. Makefile.in's keep a reasonable size. * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T are no longer shipped, since Autoconf 2.52 provides them (both as AM_ and AC_). * `#line' of Lex and Yacc files are properly set. * EXTRA_DIST can contain generated directories. * Support for dot-less extensions in suffix rules. * The part of the distcheck target that checks whether distclean actually cleans all built files has been moved in a separate target, distcleancheck, so it can be overridden easily. * `make distcheck' will pass additional options defined in $(DISTCHECK_CONFIGURE_FLAGS) to configure. * Fixed CDPATH portability problems, in particular for MacOS X. * Fixed handling of nobase_ targets. * Fixed support of implicit rules leading to .lo objects. * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON * Added uninstall-hook target * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct. You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead. (Note that "pkgname" is not "tarname", see the manual for details.) It is also possible to pass a list of global Automake options as first argument to this new form of AM_INIT_AUTOMAKE. * Compiler-based assembler is now called `CCAS'; people expected `AS' to be a real assembler. * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required. * aclocal and automake are also installed with the version number appended, and some of the install directory names have changed. This lets you have multiple versions installed simultaneously. * Support for parsers and lexers in subdirectories. New in 1.5: * Support for `configure.ac'. * Support for `else COND', `endif COND' and negated conditions `!COND'. * `make dist-all' is much faster. * Allows '@' AC_SUBSTs in macro names. * Faster AM_INIT_AUTOMAKE (requires update of `missing' script) * User-side dependency tracking. Developers no longer need GNU make * Python support * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional * Most files are correctly handled if they appear in subdirs For instance, a _DATA file can appear in a subdir * GNU tar is no longer required for `make dist' * Added support for `dist_' and `nodist_' prefixes * Added support for `nobase_' prefix * Compiled Java support * Support for per-executable and per-library compilation flags * Many bug fixes New in 1.4: * Added support for the Fortran 77 programming language. * Re-indexed the Automake Texinfo manual. * Added `AM_FOOFLAGS' variable for each compiler invocation; e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags * Support for latest autoconf, including support for objext * Can now put `.' in SUBDIRS to control build order * `include' command and `+=' support for macro assignment * Dependency tracking no long susceptible to deleted header file problem * Maintainer mode now a conditional. @MAINT@ is now an anachronism. * Bug fixes New in 1.3: * Bug fixes * Better Cygwin32 support * Support for suffix rules with _SOURCES variables * New options `readme-alpha' and `check-news'; Gnits mode sets these * @LEXLIB@ no longer required when lex source seen Lex support in `missing', and new lex macro. Update your missing script. * Built-in support for assembly * aclocal gives error if `AM_' macro not found * Passed YFLAGS, not YACCFLAGS, to yacc * AM_PROG_CC_STDC does not have to come before AC_PROG_CPP * Dependencies computed as a side effect of compilation * Preliminary support for Java * DESTDIR support at "make install" time * Improved ansi2knr support; you must use the latest ansi2knr.c (included) New in 1.2: * Bug fixes * Better DejaGnu support * Added no-installinfo option * Added Emacs Lisp support * Added --no-force option * Included `aclocal' program * Automake will now generate rules to regenerate aclocal.m4, if appropriate * Now uses `AM_' macro names everywhere * ansi2knr option can have directory prefix (eg `../lib/ansi2knr') ansi2knr now works correctly on K&R sources * Better C++, yacc, lex support * Will compute _DEPENDENCIES variables automatically if not supplied * Will interpolate $(...) and ${...} when examining contents of a variable * .deps files now in build directory, not source directory; dependency handling generally rewritten * DATA, MANS and BUILT_SOURCES no longer included in distribution * can now put config.h into a subdir * Added dist-all target * Support for install-info program (see texinfo 3.9) * Support for "yacc -d" * configure substitutions are automatically discovered and included in generated Makefile.in * Special --cygnus mode * OMIT_DEPENDENCIES can now hold list of dependencies to be omitted when making distribution. Some dependencies are auto-ignored. * Changed how libraries are specified in _LIBRARIES variable * Full libtool support, from Gord Matzigkeit * No longer have to explicitly touch stamp-h when using AC_CONFIG_HEADER; AM_CONFIG_HEADER handles it automatically * Texinfo output files no longer need .info extension * Added `missing' support * Cygwin32 support * Conditionals in Makefile.am, from Ian Taylor New in 1.0: * Bug fixes * distcheck target runs install and installcheck targets * Added preliminary support for DejaGnu. New in 0.33: * More bug fixes * More checking * More libtool fixes from Gord Matzigkeit; libtool support is still preliminary however * Added support for jm_MAINTAINER_MODE * dist-zip support * New "distcheck" target New in 0.32: * Many bug fixes * mkinstalldirs and mdate-sh now appear in directory specified by AC_CONFIG_AUX_DIR. * Removed DIST_SUBDIRS, DIST_OTHER * AC_ARG_PROGRAM only required when an actual program exists * dist-hook target now run before distribution packaged up; idea from Dieter Baron.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

COPYING000064400000043103152532470230005603 0ustar00 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.
