3 * WARNING: Future backward-incompatibilities!
5 - Automake 1.14 will require Autoconf 2.70 or later (which is still
6 unreleased at the moment of writing, but is planned to be released
7 before Automake 1.14 is).
9 - Automake 1.14 will drop support for the long-deprecated 'configure.in'
10 name for the Autoconf input file. You are advised to start using
11 recommended name 'configure.ac' instead, ASAP.
13 - The ACLOCAL_AMFLAGS special make variable will be fully deprecated
14 in Automake 1.14 (where it will raise warnings in the "obsolete"
15 category). You are advised to start relying on the new Automake
16 support for AC_CONFIG_MACRO_DIRS instead (which was introduced in
19 - Support for IRIX and the SGI C/C++ compilers will be removed in
20 Automake 1.14: they have seen their last release in 2006, and SGI
21 is expected to retire support from them in December 2013; see
22 <http://www.sgi.com/services/support/irix_mips_support.html> for
25 - Future versions of Automake might remove support for MS-DOS and
26 Windows 95/98/ME (support for them was offered by relying on the
27 DJGPP project). Note however that both Cygwin and MSYS/MinGW on
28 modern Windows versions will continue to be fully supported.
30 - Support for the long-deprecated INCLUDES variable will be removed
31 altogether in Automake 1.14. The AM_CPPFLAGS variable should be
34 - Automake-provided scripts and makefile recipes might (finally!)
35 start assuming a POSIX shell in Automake 1.14.
37 - Starting from Automake 1.14, third-party m4 files located in the
38 system-wide aclocal directory, as well as in any directory listed
39 in the ACLOCAL_PATH environment variable, will take precedence
40 over "built-in" Automake macros. For example (assuming Automake
41 is installed in the /usr/local hierarchy), a definition of the
42 AM_PROG_VALAC macro found in '/usr/local/share/aclocal/my-vala.m4'
43 should take precedence over the same-named automake-provided macro
44 (defined in '/usr/local/share/aclocal-1.14/vala.m4').
46 * Obsolescent features:
48 - Use of suffix-less info files (that can be specified through the
49 '@setfilename' macro in Texinfo input files) is discouraged, and
50 its use will raise warnings in the 'obsolete' category.
52 - Use of Texinfo input files with '.txi' or '.texinfo' extensions
53 is discouraged, and its use will raise warnings in the 'obsolete'
54 category. You are advised to simply use the '.texi' extension
57 * Documentation fixes:
59 - The long-deprecated but still supported two-arguments invocation form
60 of AM_INIT_AUTOMAKE is documented once again. This seems the sanest
61 thing to do, given that support for such an usage might need to remain
62 in place for a unspecified amount of time in order to cater for people
63 who want to define the version number for their package dynamically at
64 configure runtime (unfortunately, Autoconf does not yet support this
65 scenario, so we cannot delegate the work to it).
67 - The serial testsuite harness is no longer reported as "deprecated",
68 but as "discouraged". We have no plan to remove it, not to make its
69 use cause runtime warnings.
71 - The parallel testsuite is no longer reported as "experimental"; it
72 is well tested, ans should be stable now.
76 - The obsolete macros AM_CONFIG_HEADER or AM_PROG_CC_STDC work once
77 again, as they did in Automake 1.12.x (albeit printing runtime
78 warnings in the 'obsolete' category). Removing them has turned
79 out to be a very bad idea, because it complicated distro packing
80 enormously. Making them issue fatal warnings, as we did in
81 Automake 1.13, has turned out to be a similarly very bad idea,
82 for exactly the same reason.
84 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
90 - Use of the obsolete macros AM_CONFIG_HEADER or AM_PROG_CC_STDC now
91 causes a clear and helpful error message, instead of obscure ones
92 (issue introduced in Automake 1.13).
94 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
100 - ylwrap renames properly header guards in generated header files
101 (*.h), instead of leaving Y_TAB_H.
103 - ylwrap now also converts header guards in implementation files
104 (*.c). Because ylwrap failed to rename properly #include in the
105 implementation files, current versions of Bison (e.g., 2.7)
106 duplicate the generated header file in the implementation file.
107 The header guard then protects the implementation file from
108 duplicate definitions from the header file.
110 * Version requirements:
112 - Autoconf 2.65 or greater is now required.
114 - The rules to build PDF and DVI output from Texinfo input now
115 require Texinfo 4.9 or later.
119 - Support for the "Cygnus-style" trees (once enabled by the 'cygnus'
120 option) has been removed. See discussion about automake bug#11034
121 for more background: <http://debbugs.gnu.org/11034>.
123 - The deprecated aclocal option '--acdir' has been removed. You
124 should use the options '--automake-acdir' and '--system-acdir'
125 instead (which have been introduced in Automake 1.11.2).
127 - The following long-obsolete m4 macros have been removed:
129 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
130 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
131 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
132 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
133 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
134 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
135 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
136 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
137 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
138 of the now-removed automatic de-ANSI-fication
141 - All the "old alias" macros in 'm4/obsolete.m4' have been removed.
143 - Use of the long-deprecated two- and three-arguments invocation forms
144 of the AM_INIT_AUTOMAKE is no longer documented. It's still supported
145 though (albeit with a warning in the 'obsolete' category), to cater
146 for people who want to define the version number for their package
147 dynamically (e.g., from the current VCS revision). We'll have to
148 continue this support until Autoconf itself is fixed to allow better
149 support for such dynamic version numbers.
151 * Elisp byte-compilation:
153 - The byte compilation of '.el' files into '.elc' files is now done
154 with a suffix rule. This has simplified the compilation process, and
155 more importantly made it less brittle. The downside is that emacs is
156 now invoked once for each '.el' files, which cause some noticeable
157 slowdowns. These should however be mitigated on multicore machines
158 (which are becoming the norm today) if concurrent make ("make -j")
161 - Elisp files placed in a subdirectory are now byte-compiled to '.elc'
162 files in the same subdirectory; for example, byte-compiling of file
163 'sub/foo.el' file will result in 'sub/foo.elc' rather than in
164 'foo.elc'. This behaviour is backward-incompatible with older
165 Automake versions, but it is more natural and more sane. See also
168 - The Emacs invocation performing byte-compilation of '.el' files honors
169 the $(AM_ELCFLAGS) and $(ELCFLAGS) variables; as typical, the former
170 one is developer-reserved and the latter one user-reserved.
172 - The 'elisp-comp' script, once provided by Automake, has been rendered
173 obsoleted by the just-described changes, and thus removed.
175 * Changes to Automake-generated testsuite harnesses:
177 - The parallel testsuite harness (previously only enabled by the
178 'parallel-tests' option) is the default one; the older serial
179 testsuite harness will still be available through the use of the
180 'serial-tests' option (introduced in Automake 1.12).
182 - The 'color-tests' option is now unconditionally activated by default.
183 In particular, this means that testsuite output is now colorized by
184 default if the attached terminal seems to support ANSI escapes, and
185 that the user can force output colorization by setting the variable
186 AM_COLOR_TESTS to "always". The 'color-tests' is still recognized
187 for backward-compatibility, although it's a handled as a no-op now.
189 * Silent rules support:
191 - Support for silent rules is now always active in Automake-generated
192 Makefiles. So, although the verbose output is still the default,
193 the user can now always use "./configure --enable-silent-rules" or
194 "make V=0" to enable quieter output in the package he's building.
196 - The 'silent-rules' option has now become a no-op, preserved for
197 backward-compatibility only. In particular, its use no longer
198 disables the warnings in the 'portability-recursive' category.
202 - The rules to build PDF and DVI files from Texinfo input now require
203 Texinfo 4.9 or later.
205 - The rules to build PDF and DVI files from Texinfo input now use the
206 '--build-dir' option, to keep the auxiliary files used by texi2dvi
207 and texi2pdf around without cluttering the build directory, and to
208 make it possible to run the "dvi" and "pdf" recipes in parallel.
210 * Automatic remake rules and 'missing' script:
212 - The 'missing' script no longer tries to update the timestamp of
213 out-of-date files that require a maintainer-specific tool to be
214 remade, in case the user lacks such a tool (or has a too-old version
215 of it). It just gives a useful warning, and in some cases also a
216 tip about how to obtain such a tool.
218 - The missing script has thus become useless as a (poor) way to work
219 around the sketched-timestamps issues that can happen for projects
220 that keep generated files committed in their VCS repository. Such
221 projects are now encouraged to write a custom "fix-timestamps.sh"
222 script to avoid such issues; a simple example is provided in the
223 "CVS and generated files" chapter of the automake manual.
227 - The user can now define his own recursive targets that recurse
228 in the directories specified in $(SUBDIRS). This can be done by
229 specifying the name of such targets in invocations of the new
230 'AM_EXTRA_RECURSIVE_TARGETS' m4 macro.
234 - Any failure in the recipe of the "tags", "ctags", "cscope" or
235 "cscopelist" targets in a subdirectory is now propagated to the
236 top-level make invocation.
238 - Tags are correctly computed also for files in _SOURCES variables that
239 only list files with non-standard suffixes (see automake bug#12372).
241 * Improvements to aclocal and related rebuilds rules:
243 - Autoconf-provided macros AC_CONFIG_MACRO_DIR and AC_CONFIG_MACRO_DIRS
244 are now traced by aclocal, and can be used to declare the local m4
245 include directories. Formerly, one had to specify it with an explicit
246 '-I' option to the 'aclocal' invocation.
248 - The special make variable ACLOCAL_AMFLAGS is deprecated; future
249 Automake versions will warn about its use, and later version will
250 remove support for it altogether.
252 * The depcomp script:
254 - Dropped support for libtool 1.4.
256 - Various internal refactorings. They should cause no visible change,
257 but the chance for regression is there anyway, so please report any
258 unexpected or suspicious behaviour.
260 - Support for pre-8.0 versions of the Intel C Compiler has been dropped.
261 This should cause no problem, since icc 8.0 has been released in
262 December 2003 -- almost nine years ago.
264 - Support for tcc (the Tiny C Compiler) has been improved, and is now
265 handled through a dedicated 'tcc' mode.
269 - ylwrap generates header guards with a single '_' for series of non
270 alphabetic characters, instead of several. This is what Bison >=
273 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
275 Bugs fixed in 1.12.6:
277 * Python-related bugs:
279 - The default installation location for python modules has been improved
280 for Python 3 on Debian and Ubuntu systems, changing from:
282 ${prefix}/lib/python3/dist-packages
286 ${prefix}/lib/python3.x/site-packages
288 This change should ensure modules installed using the default ${prefix}
289 "/usr/local" are found by default by system python 3.x installations.
290 See automake bug#10227.
292 - Python byte-compilation supports the new layout mandated by PEP-3147,
293 with its __pycache__ directory (automake bug#8847).
295 * Build system issues:
297 - The maintainer rebuild rules for Makefiles and aclocal.m4 in
298 Automake's own build system works correctly again (bug introduced
303 - The Vala-related tests has been changed to adjust to the removal of
304 the 'posix' profile in the valac compiler. See automake bug#12934
307 - Some spurious testsuite failures related to older tools and systems
310 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
316 - The AM_PROG_VALAC macro has been enhanced to takes two further
317 optional arguments; it's signature now being
319 AM_PROG_VALAC([MINIMUM-VERSION], [ACTION-IF-FOUND],
320 [ACTION-IF-NOT-FOUND])
322 - By default, AM_PROG_VALAC no longer aborts the configure invocation
323 if the Vala compiler found is too old, but simply prints a warning
324 messages (as it did when the Vala compiler was not found). This
325 should avoid unnecessary difficulties for end users that just want
326 to compile the unmodified, distributed Vala-generated C sources,
327 but happens to have an old Vala compiler in their PATH. This fixes
330 - If no proper Vala compiler is found at configure runtime, AM_PROG_VALAC
331 will set the AC_SUBST'd variable 'VALAC' to 'valac' rather than to ':'.
332 This is a better default, because with it a triggered makefile rule
333 invoking a Vala compilation will clearly fail with an informative error
334 message like "valac: command not found", rather than silently, with
335 the error possibly going unnoticed or triggering harder-to-diagnose
336 fallout failures in later steps.
338 * Miscellaneous changes:
340 - automake and aclocal no longer honours the 'perllibdir' environment
341 variable. That had always been intended only as an hack required in
342 the testsuite, not meant for any use beyond that.
344 Bugs fixed in 1.12.5:
346 * Long-standing bugs:
348 - Automake no longer generates spurious remake rules invoking autoheader
349 to regenerate the template corresponding to header files specified after
350 the first one in AC_CONFIG_HEADERS (automake bug#12495).
352 - When wrapping Microsoft tools, the 'compile' script falls back to
353 finding classic 'libname.a' style libraries when 'name.lib' and
354 'name.dll.lib' aren't available.
356 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
360 * Warnings and deprecations:
362 - Warnings in the 'obsolete' category are enabled by default both in
363 automake and aclocal.
365 * Miscellaneous changes:
367 - Some testsuite weaknesses and spurious failures have been fixed.
369 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
373 * Miscellaneous changes:
375 - The '.m4' files provided by Automake no longer define serial numbers.
376 This should cause no difference in the behaviour of aclocal though.
378 - Some testsuite weaknesses and spurious failures have been fixed.
380 - There is initial support for automatic dependency tracking with the
381 Portland Group C/C++ compilers, thanks to the new new depmode 'pgcc'.
383 Bugs fixed in 1.12.3:
385 * Long-standing bugs:
387 - Instead of renaming only self-references of files (typically for
388 #lines), ylwrap now also renames references to the other generated
389 files. This fixes support for GLR and C++ parsers from Bison (PR
390 automake/491 and automake bug#7648): 'parser.c' now properly
391 #includes 'parser.h' instead of 'y.tab.h'.
393 - Generated files unknown to ylwrap are now preserved. This fixes
394 C++ support for Bison (automake bug#7648): location.hh and the
395 like are no longer discarded.
397 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
401 * Warnings and deprecations:
403 - Automake now issues a warning (in the 'portability' category) if
404 'configure.in' is used instead of 'configure.ac' as the Autoconf
405 input file. Such a warning will also be present in the next
406 Autoconf version (2.70).
410 - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
411 order (as done by the other recursive rules), rather than in the
412 inverse order. They used to do that in order to work a round a
413 limitation in an older implementation of the automatic dependency
414 tracking support, but that limitation had been lifted years ago
415 already, when the automatic dependency tracking based on side-effects
416 of compilation had been introduced.
418 - Cleaning rules for compiled objects (both "plain" and libtool) work
419 better when subdir objects are involved, not triggering a distinct
420 'rm' invocation for each such object. They do so by removing *any*
421 compiled object file that is in the same directory of a subdir
422 object. See automake bug#10697.
424 * Silent rules support:
426 - A new predefined $(AM_V_P) make variable is provided; it expands
427 to a shell conditional that can be used in recipes to know whether
428 make is being run in silent or verbose mode.
430 Bugs fixed in 1.12.2:
432 * SECURITY VULNERABILITIES!
434 - The 'distcheck' recipe no longer grants temporary world-write
435 permissions on the extracted distdir. Even if such rights were
436 only granted for a vanishingly small time window, the implied
437 race condition proved to be enough to allow a local attacker
438 to run arbitrary code with the privileges of the user running
439 "make distcheck". This is CVE-2012-3386.
441 * Long-standing bugs:
443 - The "recheck" targets behaves better in the face of build failures
444 related to previously failed tests. For example, if a test is a
445 compiled program that must be rerun by "make recheck", and its
446 compilation fails, it will still be rerun by further "make recheck"
447 invocations. See automake bug#11791.
449 * Bugs introduced by 1.12.1:
451 - Automake provides once again the '$(mkdir_p)' make variable and the
452 '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
453 for better backward-compatibility.
455 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
459 * New supported languages:
461 - Support for Objective C++ has been added; it should work similarly to
462 the support for Objective C.
464 * Deprecated obsolescent features:
466 - Use of the long-deprecated two- and three-arguments invocation forms
467 of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
468 category. Starting from some future major Automake release (likely
469 post-1.13), such usages will no longer be allowed.
471 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
472 now deprecated (its use triggers a warning in the 'obsolete' category).
473 It will be removed in the next major Automake release (1.13).
475 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
476 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
477 m4 macro are deprecated, eliciting a warning in the 'obsolete'
480 * Miscellaneous changes:
482 - The Automake test cases now require a proper POSIX-conforming shell.
483 Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) will no longer
484 be accepted. In most cases, the user shouldn't have to specify such
485 POSIX shell explicitly, since it will be looked up at configure time.
486 Still, when this lookup fails, or when the user wants to override its
487 conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be used (pointing
488 to the shell that will be used to run the Automake test cases).
490 Bugs fixed in 1.12.1:
492 * Bugs introduced by 1.12:
494 - Several weaknesses in Automake's own build system and test suite
497 * Bugs introduced by 1.11.3:
499 - When given non-option arguments, aclocal rejects them, instead of
500 silently ignoring them.
502 * Long-standing bugs:
504 - When the 'color-tests' option is in use, forcing of colored testsuite
505 output through "AM_COLOR_TESTS=always" works even if the terminal is
506 a non-ANSI one, i.e., if the TERM environment variable has a value of
509 - Several inefficiencies and poor performances in the implementation
510 of the parallel-tests 'check' and 'recheck' targets have been fixed.
512 - The post-processing of output "#line" directives done the ylwrap
513 script is more faithful w.r.t. files in a subdirectory; for example,
514 if the processed file is "src/grammar.y", ylwrap will correctly
515 produce directives like:
516 #line 7 "src/grammar.y"
521 * Bugs with new Perl versions:
523 - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
525 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
529 * Obsolete features removed:
531 - The never documented nor truly used script 'acinstall' has been
534 - Support for automatic de-ANSI-fication has been removed.
536 - The support for the "obscure" multilib feature has been removed
537 from Automake core (but remains available in the 'contrib/'
538 directory of the Automake distribution).
540 - Support for ".log -> .html" conversion and the check-html and
541 recheck-html targets has been removed from Automake core (but
542 remains available in the 'contrib/' directory of the Automake
545 - The deprecated 'lzma' compression format for distribution archives
546 has been removed, in favor of 'xz' and 'lzip'.
548 - The obsolete AM_WITH_REGEX macro has been removed.
550 - The long-deprecated options '--output-dir', '--Werror' and
551 '--Wno-error' have been removed.
553 - The chapter on the history of Automake has been moved out of the
554 reference manual, into a new dedicated Texinfo file.
558 - New 'cscope' target to build a cscope database for the source tree.
560 * Changes to Automake-generated testsuite harnesses:
562 - The new automake option 'serial-tests' has been introduced. It can
563 be used to explicitly instruct automake to use the older serial
564 testsuite harness. This is still the default at the moment, but it
565 might change in future versions.
567 - The 'recheck' target (provided by the parallel testsuite harness) now
568 depends on the 'all' target. This allows for a better user-experience
569 in test-driven development. See automake bug#11252.
571 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
572 and unexpected or internal error, or a failure to set up the test case
573 scenario) have their outcome reported as an 'ERROR' now. Previous
574 versions of automake reported such an outcome as a 'FAIL' (the only
575 difference with normal failures being that hard errors were counted
576 as failures even when the test originating them was listed in
579 - The testsuite summary displayed by the parallel-test harness has a
580 completely new format, that always list the numbers of passed, failed,
581 xfailed, xpassed, skipped and errored tests, even when these numbers
582 are zero (but using smart coloring when the color-tests option is in
585 - The default testsuite driver offered by the 'parallel-tests' option is
586 now implemented (partly at least) with the help of automake-provided
587 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
588 on code in the generated Makefile.in.
589 This has two noteworthy implications. The first one is that projects
590 using the 'parallel-tests' option should now either run automake with
591 the '--add-missing' option, or manually copy the 'test-driver' script
592 into their tree. The second, and more important, implication is that
593 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
594 no longer be used to define a test runner, and the command specified
595 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
596 program or script. For example, this is still a valid usage (albeit
599 TESTS_ENVIRONMENT = \
600 if test -n '$(STRICT_TESTS)'; then \
601 maybe_errexit='-e'; \
605 LOG_COMPILER = $(SHELL) $$maybe_errexit
607 OTOH, this is no longer a valid usage:
609 TESTS_ENVIRONMENT = \
610 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
614 TESTS_ENVIRONMENT = \
615 run_with_perl_or_shell () \
617 if grep -q '^#!.*perl' $$1; then
623 LOG_COMPILER = run_with_perl_or_shell
625 - The package authors can now use customary testsuite drivers within
626 the framework provided by the 'parallel-tests' testsuite harness.
627 Consistently with the existing syntax, this can be done by defining
628 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
630 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
631 to redirect/define file descriptors used by the test scripts.
633 - The parallel-tests harness generates now, in addition the '.log' files
634 holding the output produced by the test scripts, a new set of '.trs'
635 files, holding "metadata" derived by the execution of the test scripts;
636 among such metadata are the outcomes of the test cases run by a script.
638 - Initial and still experimental support for the TAP test protocol is
641 * Changes to Yacc and Lex support:
643 - C source and header files derived from non-distributed Yacc and/or
644 Lex sources are now removed by a simple "make clean" (while they were
645 previously removed only by "make maintainer-clean").
647 - Slightly backward-incompatible change, relevant only for use of Yacc
648 with C++: the extensions of the header files produced by the Yacc
649 rules are now modelled after the extension of the corresponding
650 sources. For example, yacc files named "foo.y++" and "bar.yy" will
651 produce header files named "foo.h++" and "bar.hh" respectively, where
652 they would have previously produced header files named simply "foo.h"
653 and "bar.h". This change offers better compatibility with 'bison -o'.
655 * Miscellaneous changes:
657 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
658 rather than 1, if the vala compiler found is too old.
660 - The build system of Automake itself now avoids the use of make
661 recursion as much as possible.
663 - Automake now prefers to quote 'like this' or "like this", rather
664 than `like this', in diagnostic message and generated Makefiles,
665 to accommodate the new GNU Coding Standards recommendations.
667 - Automake has a new option '--print-libdir' that prints the path of the
668 directory containing the Automake-provided scripts and data files.
670 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
672 - The rules to create pdf, dvi and ps output from Texinfo files now
673 works better with modern 'texi2dvi' script, by explicitly passing
674 it the '--clean' option to ensure stray auxiliary files are not
675 left to clutter the build directory.
677 - Automake can now generate silenced rules for texinfo outputs.
679 - Some auxiliary files that are automatically distributed by Automake
680 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
681 C sources) might now be listed in the DIST_COMMON variable in many
682 Makefile.in files, rather than in the top-level one.
684 - Messages of types warning or error from 'automake' and 'aclocal'
685 are now prefixed with the respective type, and presence of -Werror
688 - Automake's early configure-time sanity check now tries to avoid
689 sleeping for a second, which slowed down cached configure runs
690 noticeably. In that case, it will check back at the end of the
691 configure script to ensure that at least one second has passed, to
692 avoid time stamp issues with makefile rules rerunning autotools
695 - The warnings in the category 'extra-portability' are now enabled by
696 '-Wall'. In previous versions, one has to use '-Wextra-portability'
701 - Various minor bugfixes for recent or long-standing bugs.
703 * Bugs introduced by 1.11:
705 - The AM_COND_IF macro also works if the shell expression for the
706 conditional is no longer valid for the condition.
708 - The automake-provided parallel testsuite harness no longer fails
709 with BSD make used in parallel mode when there are test scripts in
710 a subdirectory, like in:
712 TESTS = sub/foo.test sub/bar.test
714 * Long-standing bugs:
716 - Automake's own build system finally have a real "installcheck" target.
718 - Vala-related cleanup rules are now more complete, and work better in
721 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
722 now automatically distributed also if the directory of the auxiliary
723 files coincides with the top-level directory.
725 - Automake now detects the presence of the '-d' flag in the various
726 '*YFLAGS' variables even when their definitions involve indirections
727 through other variables, such as in:
729 AM_YFLAGS = $(foo_opts)
731 - Automake now complains if a '*YFLAGS' variable has any conditional
732 content, not only a conditional definition.
734 - Explicit enabling and/or disabling of Automake warning categories
735 through the '-W...' options now always takes precedence over the
736 implicit warning level implied by Automake strictness (foreign, gnu
737 or gnits), regardless of the order in which such strictness and
738 warning flags appear. For example, a setting like:
739 AUTOMAKE_OPTIONS = -Wall --foreign
740 will cause the warnings in category 'portability' to be enabled, even
741 if those warnings are by default disabled in 'foreign' strictness.
743 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
745 Bugs fixed in 1.11.5:
747 * Bugs introduced by 1.11.3:
749 - Vala files with '.vapi' extension are now recognized and handled
750 correctly again. See automake bug#11222.
752 - Vala support work again for projects that contain some program
753 built from '.vala' (and possibly '.c') sources and some other
754 program built from '.c' sources *only*. See automake bug#11229.
756 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
760 * Miscellaneous changes:
762 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
763 symbol index) modifiers as well as the "s" action, as the symbol index
764 is created unconditionally by Microsoft lib. Also, the "q" (quick)
765 action is now a synonym for "r" (replace). Also, the script has been
766 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
768 - When the 'compile' script is used to wrap MSVC, it now accepts an
769 optional space between the -I, -L and -l options and their respective
770 arguments, for better POSIX compliance.
772 - There is an initial, experimental support for automatic dependency
773 tracking with tcc (the Tiny C Compiler). Its associated depmode is
774 currently recognized as "icc" (but this and other details are likely
775 to change in future versions).
777 - Automatic dependency tracking now works also with the IBM XL C/C++
778 compilers, thanks to the new new depmode 'xlc'.
780 Bugs fixed in 1.11.4:
782 * Bugs introduced by 1.11.2:
784 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
785 no longer cause spurious failures upon "make install".
787 - The user can now instruct the 'uninstall-info' rule not to update
788 the '${infodir}/dir' file by exporting the environment variable
789 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
790 with how the 'install-info' rule operates since automake 1.11.2.
792 * Long-standing bugs:
794 - It is now possible for a foo_SOURCES variable to hold Vala sources
795 together with C header files, as well as with sources and headers for
796 other supported languages (e.g., C++). Previously, only mixing C and
797 Vala sources was supported.
799 - If "aclocal --install" is used, and the first directory specified with
800 '-I' is non-existent, aclocal will now create it before trying to copy
803 - An empty declaration of a "foo_PRIMARY" no longer cause the generated
804 install rules to create an empty $(foodir) directory; for example, if
805 Makefile.am contains something like:
809 pkglibexec_SCRIPTS += bar.sh
812 the $(pkglibexec) directory will not be created upon "make install".
814 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
818 * Miscellaneous changes:
820 - Automake's own build system is more silent by default, making use of
821 the 'silent-rules' option.
823 - The master copy of the 'gnupload' script is now maintained in gnulib,
826 - The 'missing' script no longer tries to wrap calls to 'tar'.
828 - "make dist" no longer wraps 'tar' invocations with the 'missing'
829 script. Similarly, the obsolescent variable '$(AMTAR)' (which you
830 shouldn't be using BTW ;-) no longer invokes the 'missing' script
831 to wrap tar, but simply invokes the 'tar' program itself.
833 - "make dist" can now create lzip-compressed tarballs.
835 - In the Automake info documentation, the Top node and the nodes about
836 the invocation of the automake and aclocal programs have been renamed;
837 now, calling "info automake" will open the Top node, while calling
838 "info automake-invocation" and "info aclocal-invocation" will access
839 the nodes about the invocation of respectively automake and aclocal.
841 - Automake is now distributed as a gzip-compressed and an xz-compressed
842 tarball. Previously, bzip2 was used instead of xz.
844 - The last relics of Python 1.5 support have been removed from the
845 AM_PATH_PYTHON macro.
847 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
848 and adds them to the normal list of dependencies, but without
849 overwriting the foo_DEPENDENCIES variable, which is normally computed
852 Bugs fixed in 1.11.3:
854 * Bugs introduced by 1.11.2:
856 - Automake now correctly recognizes the prefix/primary combination
857 'pkglibexec_SCRIPTS' as valid.
859 - The parallel-tests harness no longer trips on sed implementations
860 with stricter limits on the length of input lines (problem seen at
863 * Long-standing bugs:
865 - The "deleted header file problem" for *.am files is avoided by stub
866 rules. This allows 'make' to trigger a rerun of 'automake' also if
867 some previously needed '.am' file has been removed.
869 - The 'silent-rules' option now generates working makefiles even
870 for the uncommon 'make' implementations that do not support the
871 nested-variables extension to POSIX 2008. For such 'make'
872 implementations, whether a build is silent is determined at
873 configure time, and cannot be overridden at make time with
874 "make V=0" or "make V=1".
876 - Vala support now works better in VPATH setups.
878 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
882 * Changes to aclocal:
884 - The `--acdir' option is deprecated. Now you should use the new options
885 `--automake-acdir' and `--system-acdir' instead.
887 - The `ACLOCAL_PATH' environment variable is now interpreted as a
888 colon-separated list of additional directories to search after the
889 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
890 and before the system acdir (by default ${prefix}/share/aclocal).
892 * Miscellaneous changes:
894 - The Automake support for automatic de-ANSI-fication has been
895 deprecated. It will probably be removed in the next major Automake
898 - The `lzma' compression scheme and associated automake option `dist-lzma'
899 is obsoleted by `xz' and `dist-xz' due to upstream changes.
901 - You may adjust the compression options used in dist-xz and dist-bzip2.
902 The default is now merely -e for xz, but still -9 for bzip; you may
903 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
904 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
906 - The `compile' script now converts some options for MSVC for a better
907 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
909 - The py-compile script now accepts empty arguments passed to the options
910 `--destdir' and `--basedir', and complains about unrecognized options.
911 Moreover, a non-option argument or a special `--' argument terminates
914 - A developer that needs to pass specific flags to configure at "make
915 distcheck" time can now, and indeed is advised to, do so by defining
916 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
917 instead of the old DISTCHECK_CONFIGURE_FLAGS.
918 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
919 user; still, the old Makefile.am files that used to define it will
920 still continue to work as before.
922 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
923 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
924 This new macro is required for LIBRARIES and LTLIBRARIES when automake
925 is run with -Wextra-portability and -Werror.
927 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
928 file generated by automake-provided rules by defining the special make
929 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
931 - The `install-info' rule can now be instructed not to create/update
932 the `${infodir}/dir' file, by exporting the new environment variable
933 `AM_UPDATE_INFO_DIR' to the value "no".
935 Bugs fixed in 1.11.2:
937 * Bugs introduced by 1.11:
939 - The parallel-tests driver no longer produces erroneous results with
940 Tru64/OSF 5.1 sh upon unreadable log files.
942 - The `parallel-tests' test driver does not report spurious successes
943 when used with concurrent FreeBSD make (e.g., "make check -j3").
945 - When the parallel-tests driver is in use, automake now explicitly
946 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
947 instead of issuing confusing and apparently unrelated error messages
948 (e.g., "non-POSIX variable name", "bad characters in variable name",
949 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
950 silently producing broken `Makefile.in' files.
952 - The `silent-rules' option now truly silences all compile rules, even
953 when dependency tracking is disabled. Also, when `silent-rules' is
954 not used, `make' output no longer contains spurious backslash-only
955 lines, thus once again matching what Automake did before 1.11.
957 - The AM_COND_IF macro also works if the shell expression for the
958 conditional is no longer valid for the condition.
960 * Long-standing bugs:
962 - The order of Yacc and Lex flags is fixed to be consistent with other
963 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
964 $(LFLAGS), so that the user variables override the developer variables.
966 - "make distcheck" now correctly complains also when "make uninstall"
967 leaves one and only one file installed in $(prefix).
969 - A "make uninstall" issued before a "make install", or after a mere
970 "make install-data" or a mere "make install-exec" does not spuriously
973 - Automake now warns about more primary/directory invalid combinations,
974 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
976 - Rules generated by Automake now try harder to not change any files when
977 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
978 Yacc source files and the rule to update config.h.
980 - Several scripts and the parallel-tests testsuite driver now exit with
981 the right exit status upon receiving a signal.
983 - A per-Makefile.am setting of -Werror does not erroneously carry over
984 to the handling of other Makefile.am files.
986 - The code for automatic dependency tracking works around a Solaris
987 make bug triggered by sources containing repeated slashes when the
988 `subdir-objects' option was used.
990 - The makedepend and hp depmodes now work better with VPATH builds.
992 - Java sources specified with check_JAVA are no longer compiled for
993 "make all", but only for "make check".
995 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
996 and error out if `javadir' is undefined, instead of silently producing
997 a broken Makefile.in.
999 - aclocal and automake now honour the configure-time definitions of
1000 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
1002 - The `install-info' recipe no longer tries to guess whether the
1003 `install-info' program is from Debian or from GNU, and adaptively
1004 change its behaviour; this has proven to be frail and easy to
1007 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1009 Bugs fixed in 1.11.1:
1011 - Lots of minor bugfixes.
1013 * Bugs introduced by 1.11:
1015 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
1016 trailing white space in the test list (`TESTS = foo $(EMPTY)').
1018 * Long standing bugs:
1020 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
1021 even if the `--prefix' argument pointed outside of a system directory.
1022 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
1023 `get_python_lib' function if it points outside the configured prefix,
1024 unless the `--prefix' argument was either `/usr' or below `/System'.
1026 - The testsuite does not try to change the mode of `ltmain.sh' files from
1027 a Libtool installation (symlinked to test directories) any more.
1029 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
1030 tools are preferred in a cross-compile setup.
1032 - The distribution is tarred up with mode 755 now by the `dist*' targets.
1033 This fixes a race condition where untrusted users could modify files
1034 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
1035 build directory was world-searchable. This is CVE-2009-4029.
1037 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1041 * Version requirements:
1043 - Autoconf 2.62 or greater is required.
1045 * Changes to aclocal:
1047 - The autoconf version check implemented by aclocal in aclocal.m4
1048 (and new in Automake 1.10) is degraded to a warning. This helps
1049 in the common case where the Autoconf versions used are compatible.
1051 * Changes to automake:
1053 - The automake program can run multiple threads for creating most
1054 Makefile.in files concurrently, if at least Perl 5.7.2 is available
1055 with interpreter-based threads enabled. Set the environment variable
1056 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
1057 enable this experimental feature.
1059 * Changes to Libtool support:
1061 - Libtool generic flags are now passed to the install and uninstall
1064 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
1065 config.lt is removed correctly now.
1067 * Languages changes:
1069 - subdir-object mode works now with Fortran (F77, FC, preprocessed
1070 Fortran, and Ratfor).
1072 - For files with extension .f90, .f95, .f03, or .f08, the flag
1073 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
1075 - Files with extension .sx are also treated as preprocessed assembler.
1077 - The default source file extension (.c) can be overridden with
1078 AM_DEFAULT_SOURCE_EXT now.
1080 - Python 3.0 is supported now, Python releases prior to 2.0 are no
1083 - AM_PATH_PYTHON honors python's idea about the site directory.
1085 - There is initial support for the Vala programming language, when using
1086 Vala 0.7.0 or later.
1088 * Miscellaneous changes:
1090 - Automake development is done in a git repository on Savannah now, see
1092 http://git.sv.gnu.org/gitweb/?p=automake.git
1094 A read-only CVS mirror is provided at
1096 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
1097 checkout -d automake HEAD
1099 - "make dist" can now create xz-compressed tarballs,
1100 as well as (deprecated?) lzma-compressed tarballs.
1102 - `automake --add-missing' will by default install the GPLv3 file as
1103 COPYING if it is missing. It will also warn that the license file
1104 should be added to source control. Note that Automake will never
1105 overwrite an existing COPYING file, even when the `--force-missing'
1108 - The manual is now distributed under the terms of the GNU FDL 1.3.
1110 - Automake ships and installs man pages for automake and aclocal now.
1112 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
1114 - install-sh supports -C, which does not update the installed file
1115 (and its time stamps) if the contents did not change.
1117 - The `gnupload' script has been revamped.
1119 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
1121 - The targets `install' and `uninstall' are more efficient now, in that
1122 for example multiple files from one Automake variable such as
1123 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
1124 invocation if they do not have to be renamed.
1126 Both install and uninstall may sometimes enter (`cd' into) the target
1127 installation directory now, when no build-local scripts are used.
1129 Both install and uninstall do not fail anymore but do nothing if an
1130 installation directory variable like `bindir' is set to the empty string.
1132 For built-in rules, `make install' now fails reliably if installation
1133 of a file failed. Conversely, `make uninstall' even succeeds when
1134 issued multiple times.
1136 These changes may need some adjustments from users: For example,
1137 some `install' programs refuse to install multiple copies of the
1138 same file in one invocation, so you may need to remove duplicate
1139 entries from file lists.
1141 Also, within one set of files, say, nobase_data_DATA, the order of
1142 installation may be changed, or even unstable among different hosts,
1143 due to the use of associative arrays in awk. The increased use of
1144 awk matches a similar move in Autoconf to provide for better scaling.
1146 Further, most undocumented per-rule install command variables such as
1147 binSCRIPT_INSTALL have been removed because they are not needed any
1148 more. Packages which use them should be using the appropriate one of
1149 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
1150 counterpart, depending on the type of files and the need for automatic
1151 target directory creation.
1153 - The "deleted header file problem" for *.m4 files is avoided by
1154 stub rules. This allows `make' to trigger a rerun of `aclocal'
1155 also if some previously needed macro file has been removed.
1157 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
1158 an otherwise up to date tree.
1160 - The `color-tests' option causes colored test result output on terminals.
1162 - The `parallel-tests' option enables a new test driver that allows for
1163 parallel test execution, inter-test dependencies, lazy test execution
1164 for unit-testing, re-testing only failed tests, and formatted result output
1165 as RST (reStructuredText) and HTML. Enabling this option may require some
1166 changes to your test suite setup; see the manual for details.
1168 - The `silent-rules' option enables Linux kernel-style silent build output.
1169 This option requires the widely supported but non-POSIX `make' feature
1170 of recursive variable expansion, so do not use it if your package needs
1171 to build with `make' implementations that do not support it.
1173 To enable less verbose build output, the developer has to use the Automake
1174 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
1175 macro. The user may then set the default verbosity by passing the
1176 `--enable-silent-rules' option to `configure'. At `make' run time, this
1177 default may be overridden using `make V=0' for less verbose, and `make V=1'
1178 for backward-compatible verbose output.
1180 - New prefix `notrans_' for manpages which should not be transformed
1181 by --program-transform.
1183 - New macro AM_COND_IF for conditional evaluation and conditional
1186 - For AC_CONFIG_LINKS, if source and destination are equal, do not
1187 remove the file in a non-VPATH build. Such setups work with Autoconf
1190 - AM_MAINTAINER_MODE now allows for an optional argument specifying
1191 the default setting.
1193 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
1194 useful especially for multi-line values.
1196 - Automake's early configure-time sanity check now diagnoses an
1197 unsafe absolute source directory name and makes configure fail.
1199 - The Automake macros and rules cope better with whitespace in the
1200 current directory name, as long as the relative path to `configure'
1201 does not contain whitespace. To this end, the values of `$(MISSING)'
1202 and `$(install_sh)' may contain suitable quoting, and their expansion
1203 might need `eval'uation if used outside of a makefile. These
1204 undocumented variables may be used in several documented macros such
1205 as $(AUTOCONF) or $(MAKEINFO).
1209 * Long-standing bugs:
1211 - Fix aix dependency tracking for libtool objects.
1213 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
1214 unnecessary use of the `compile' script.
1216 - For nobase_*_LTLIBRARIES with nonempty directory components, the
1217 correct `-rpath' argument is used now.
1219 - `config.status --file=Makefile depfiles' now also works with the
1220 extra quoting used internally by Autoconf 2.62 and newer
1221 (it used to work only without the `--file=' bit).
1223 - The `missing' script works better with versioned tool names.
1225 - Semantics for `missing help2man' have been revamped:
1227 Previously, if `help2man' was not present, `missing help2man' would have
1228 the following semantics: if some man page was out of date but present, then
1229 a warning would be printed, but the exit status was 0. If the man page was
1230 not present at all, then `missing' would create a replacement man page
1231 containing an error message, and exit with a status of 2. This does not play
1232 well with `make': the next run will see this particular man page as being up
1233 to date, and will only error out on the next generated man page, if any;
1234 repeat until all pages are done. This was not desirable.
1236 These are the new semantics: if some man page is not present, and help2man
1237 is not either, then `missing' will warn and generate the replacement page
1238 containing the error message, but exit successfully. However, `make dist'
1239 will ensure that no such bogus man pages are packaged into a tarball.
1241 - Targets provided by automake behave better with `make -n', in that they
1242 take care not to create files.
1244 - `config.status Makefile... depfiles' works fine again in the presence of
1245 disabled dependency tracking.
1247 - The default no-op recursive rules for these targets also work with BSD make
1248 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
1250 - `make distcheck' works also when both a directory and some file below it
1251 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
1253 - Texinfo dvi, ps, pdf, and html output files are not removed upon
1254 `make mostlyclean' any more; only the LaTeX by-products are.
1256 - Renamed objects also work with the `subdir-objects' option and
1257 source file languages which Automake does not know itself.
1259 - `automake' now correctly complains about variable assignments which are
1260 preceded by a comment, extend over multiple lines with backslash-escaped
1261 newlines, and end in a comment sign. Previous versions would silently
1262 and wrongly ignore such assignments completely.
1264 * Bugs introduced by 1.10:
1266 - Fix output of dummy dependency files in presence of post-processed
1267 Makefile.in's again, but also cope with long lines.
1269 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
1270 that have been declared as programs in the same Makefile.
1271 This is for consistency with the analogous change to TESTS in 1.10.
1273 - Fix order of standard includes to again be `-I. -I$(srcdir)',
1274 followed by directories containing config headers.
1276 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1280 * Version requirements:
1282 - Autoconf 2.60 or greater is required.
1284 - Perl 5.6 or greater is required.
1286 * Changes to aclocal:
1288 - aclocal now also supports -Wmumble and -Wno-mumble options.
1290 - `dirlist' entries (for the aclocal search path) may use shell
1291 wildcards such as `*', `?', or `[...]'.
1293 - aclocal supports an --install option that will cause system-wide
1294 third-party macros to be installed in the local directory
1295 specified with the first -I flag. This option also uses #serial
1296 lines in M4 files to upgrade local macros.
1298 The new aclocal options --dry-run and --diff help to review changes
1299 before they are installed.
1301 - aclocal now outputs an autoconf version check in aclocal.m4 in
1302 projects using automake.
1304 For a few years, automake and aclocal have been calling autoconf
1305 (or its underlying engine autom4te) to accurately retrieve the
1306 data they need from configure.ac and its siblings. Doing so can
1307 only work if all autotools use the same version of autoconf. For
1308 instance a Makefile.in generated by automake for one version of
1309 autoconf may stop working if configure is regenerated with another
1310 version of autoconf, and vice versa.
1312 This new version check ensures that the whole build system has
1313 been generated using the same autoconf version.
1315 * Support for new Autoconf macros:
1317 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
1319 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
1320 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
1321 in different directories. However, only one instance of such a
1322 library objects directory is supported.
1324 * Change to Libtool support:
1326 - Libtool generic flags (those that go before the --mode=MODE option)
1327 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
1329 * Yacc and Lex changes:
1331 - The rebuild rules for distributed Yacc and Lex output will avoid
1332 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
1335 - ylwrap is now always used for lex and yacc source files,
1336 regardless of whether there is more than one source per directory.
1338 * Languages changes:
1340 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
1341 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
1342 tracking, unlike non-preprocessed assembler (*.s).
1344 - subdir-object mode works now with Assembler. Automake assumes
1345 that the compiler understands `-c -o'.
1347 - Preprocessed assembler (*.S) compilation now also honors
1348 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
1350 - Improved support for Objective C:
1351 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
1352 - A new section of the manual documents the support.
1354 - New support for Unified Parallel C:
1355 - AM_PROG_UPC looks for a UPC compiler.
1356 - A new section of the manual documents the support.
1358 - Per-target flags are now correctly handled in link rules.
1360 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
1361 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
1362 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
1363 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
1365 The fix for compiler flags (i.e., using maude_CFLAGS instead of
1366 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
1367 is expected to work (and actually works during compilation).
1369 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
1370 "in addition to" breaks backward compatibility with older versions.
1371 If your package used both variables, as in
1373 AM_LDFLAGS = common flags
1374 bin_PROGRAMS = a b c
1375 a_LDFLAGS = more flags
1378 and assumed *_LDFLAGS would sum up, you should rewrite it as
1380 AM_LDFLAGS = common flags
1381 bin_PROGRAMS = a b c
1382 a_LDFLAGS = $(AM_LDFLAGS) more flags
1385 This new behavior of *_LDFLAGS is more coherent with other
1386 per-target variables, and the way *_LDFLAGS variables were
1387 considered internally.
1389 * New installation targets:
1391 - New targets mandated by GNU Coding Standards:
1396 By default they will only install Texinfo manuals.
1397 You can customize them with *-local variants:
1403 - The undocumented recursive target `uninstall-info' no longer exists.
1404 (`uninstall' is in charge of removing all possible documentation
1405 flavors, including optional formats such as dvi, ps, or info even
1406 when `no-installinfo' is used.)
1408 * Miscellaneous changes:
1410 - Automake no longer complains if input files for AC_CONFIG_FILES
1411 are specified using shell variables.
1413 - clean, distribution, or rebuild rules are normally disabled for
1414 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
1415 AC_CONFIG_LINK specified using shell variables. However, if these
1416 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
1417 be able to output rules anyway.
1418 (See the Automake documentation for AC_CONFIG_FILES.)
1420 - $(EXEEXT) is automatically appended to filenames of TESTS
1421 that have been declared as programs in the same Makefile.
1422 This is mostly useful when some check_PROGRAMS are listed in TESTS.
1424 - `-Wportability' has finally been turned on by default for `gnu' and
1425 `gnits' strictness. This means, automake will complain about %-rules
1426 or $(GNU Make functions) unless you switch to `foreign' strictness or
1427 use `-Wno-portability'.
1429 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
1430 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
1431 $(mkdir_p) variable is still defined (to the same value as
1432 $(MKDIR_P)) but should be considered obsolete. If you are using
1433 $(mkdir_p) in some of your rules, please plan to update them to
1434 $(MKDIR_P) at some point.
1436 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
1437 They still work in this release, but may be withdrawn in a future one.
1439 - Inline compilation rules for gcc3-style dependency tracking are
1442 - Automake installs a "Hello World!" example package in $(docdir).
1443 This example is used throughout the new "Autotools Introduction"
1444 chapter of the manual.
1446 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1450 * Makefile.in bloat reduction:
1452 - Inference rules are used to compile sources in subdirectories when
1453 the `subdir-objects' option is used and no per-target flags are
1454 used. This should reduce the size of some projects a lot, because
1455 Automake used to output an explicit rule for each such object in
1458 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1459 object that must be built with explicit rules. It just outputs
1460 the rules required to build the kind of object considered: either
1461 the two .o and .obj rules for usual objects, or the .lo rule for
1464 * Change to Libtool support:
1466 - Libtool tags are used with libtool versions that support them.
1467 (I.e., with Libtool 1.5 or greater.)
1469 - Automake is now able to handle setups where a libtool library is
1470 conditionally installed in different directories, as in
1473 lib_LTLIBRARIES = liba.la
1475 pkglib_LTLIBRARIES = liba.la
1477 liba_la_SOURCES = ...
1479 * Changes to aclocal:
1481 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1482 really evaluated, before it decides to include them in aclocal.m4.
1483 This solves nasty problems with conditional redefinitions of
1484 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1485 *.m4 files to be included in any project using these macros.
1486 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1487 most famous instance of this bug.)
1489 - Do not complain about missing conditionally AC_REQUIREd macros
1490 that are not actually used. In 1.8.x aclocal would correctly
1491 determine which of these macros were really needed (and include
1492 only these in the package); unfortunately it would also require
1493 all of them to be present in order to run. This created
1494 situations were aclocal would not work on a tarball distributing
1495 all the macros it uses. For instance running aclocal on a project
1496 containing only the subset of the Gettext macros in use by the
1497 project did not work, because gettext conditionally requires other
1500 * Portability improvements:
1502 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1503 tar-pax. The new option filename-length-max=99 helps diagnosing
1504 filenames that are too long for tar-v7. (PR/414)
1506 - Variables aumented with `+=' are now automatically flattened (i.e.,
1507 trailing backslashes removed) and then wrapped around 80 colummns
1508 (adding trailing backslashes). In previous versions, a long series
1514 would result in a single-line definition of VAR that could possibly
1515 exceed the maximum line length of some make implementations.
1517 Non-augmented variables are still output as they are defined in
1522 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1523 Works the same as the old Fortran 77 implementation; just replace
1524 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1525 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1527 - Support for conditional _LISP.
1529 - Support for conditional -hook and -local rules (PR/428).
1531 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1533 - Automake will not write any Makefile.ins after the first error it
1534 encounters. The previous Makefile.ins (if any) will be left in
1535 place. (Warnings will not prevent output, but remember they can
1536 be turned into errors with -Werror.)
1538 - The restriction that SUBDIRS must contain direct children is gone.
1541 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1542 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1544 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1546 Bugs fixed in 1.8.5:
1548 * Long-standing bugs:
1550 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1551 so that `make distclean' and `make maintainer-clean' can work.
1553 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1555 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1557 - Polish diagnostic when no input file is found.
1559 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1561 Bugs fixed in 1.8.4:
1563 * Long-standing bugs:
1565 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1566 overridden by the user.
1568 - Honor PATH_SEPARATOR in various places of the Automake package, for
1571 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1574 - Fix install-sh so it can install the `mv' binary... using `mv'.
1576 - Fix tru64 dependency tracking for libtool objects.
1578 - Work around Exuberant Ctags when creating a TAGS files in a directory
1579 without files to scan but with subdirectories to include.
1581 * Bugs introduced by 1.8:
1583 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1584 not defined in the same conditions as the _LDADD that uses it.
1586 - Do not warn when JAVAROOT is overridden, this is legitimate.
1588 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1590 Bugs fixed in 1.8.3:
1592 * Long-standing bugs:
1594 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1595 or any of the other *dir variables contain a space.
1597 Please note that Automake does not and cannot support spaces in
1598 filenames that are involved during the build. This change affects
1599 only installation paths, so that `make install' does not bomb out
1600 in packages configured with
1601 ./configure --prefix '/c/Program Files'
1603 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1604 POSIXLY_CORRECT is set.
1606 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1607 since Autoconf 2.54, which defines LIBOBJS itself.
1609 - Fix a potential (but unlikely) race condition in parallel elisp
1610 builds. (Introduced in 1.7.3.)
1612 - Do not assume that users override _DEPENDENCIES in all conditions
1613 where Automake will try to define them.
1615 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1616 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1619 This fix also affects the $(mkdir_p) variable defined since
1620 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1621 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1623 - Secure temporary directory creation in `make distcheck'. (PR/413)
1625 - Do not generate two build rules for `parser.h' when the
1626 parser appears in two different conditionals.
1628 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1629 checking. Usually ./configure will not pick this shell; so this
1630 fix only helps cases where the shell is forced to /bin/sh.
1632 * Bugs introduced by 1.8:
1634 - In some situations (hand-written `m4_include's), aclocal would
1635 call the `File::Spec->rel2abs' method, which was only introduced
1636 in Perl 5.6. This new version reestablish support Perl 5.005.
1638 It is likely that the next major Automake releases will require at
1639 least Perl 5.6. Consider upgrading your development environment
1640 if you are still using the five-year-old Perl 5.005.
1642 - Automake would sometimes fail to define rules for targets listed
1643 in variables defined in multiple conditions. For instance on
1649 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1650 `b.$(OBJEXT): b.c' rule.
1652 * New sections in manual:
1654 - Third-Party Makefiles: how to interface third party Makefiles.
1655 - Upgrading: upgrading packages to newer Automake versions.
1656 - Multiple Outputs: handling tools that produce many outputs.
1658 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1662 * A (well known) portability bug slipped in the changes made to
1663 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1664 install anything on Tru64.
1666 * Fix install rules for conditionally built python files. (This never
1669 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1673 * Bugs introduced by 1.8:
1675 - Fix Config.pm import error with old Perl versions (at least
1676 5.005_03). One symptom is that aclocal could not find its macro
1679 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1680 created by `make install' are always world readable, even if the
1681 installer happens to have an overly restrictive umask (e.g. 077).
1682 This was a mistake and has been reverted. There are at least two
1683 reasons why we must not use `-m 0755':
1684 - it causes special bits like SGID to be ignored,
1685 - it may be too restrictive (some setups expect 775 directories).
1687 - Fix aclocal to honor definitions located in files which have been
1688 m4_included manually. aclocal 1.8 had been updated to check
1689 m4_included files for new requirements, but forgot that these
1690 m4_included files can also provide new definitions.
1692 Note that if you have such a setup, we recommend you get rid of
1693 it. In the past, there was a reason to m4_include files manually:
1694 aclocal used to duplicate entire M4 files into aclocal.m4, even
1695 files that were distributed. Some packages were therefore
1696 m4_including the distributed file directly, and playing some
1697 tricks to ensure aclocal would not copy that file to aclocal.m4,
1698 in order to limit the amount of duplication. Since aclocal 1.8.x
1699 will precisely output m4_includes for local M4 files, we recommend
1700 that you clean up your setup, removing all manual m4_includes and
1701 letting aclocal output them.
1703 - Output detailed menus in the Info version if the Automake manual,
1704 so that Emacs can locate the indexes.
1706 - configure.ac and configure were listed twice in DIST_COMMON (an
1707 internal variable where Automake lists configury files to
1708 distribute). This was harmless, but unaesthetic.
1710 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1711 This was an issue only in the Automake package itself, not in
1714 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1715 DEST:SRC. This was wrong, as some packages do
1716 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1719 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1720 argument. This caused two kinds of failures:
1721 - Rules installing data in a conditionally defined directory
1722 failed when that directory was undefined. In this case no
1723 argument was supplied.
1724 - `make installdirs' failed, because several directories were
1725 passed to $(mkdir_p). This was an issue only on platform
1726 were $(mkdir_p) is implemented with `install-sh -d'.
1727 $(mkdir_p) as been changed to accept 0 or more arguments, as
1730 * Long-standing bugs:
1732 - Fix an unexpected diagnostic occurring when users attempt
1733 to override some internal variables that Automake appends to.
1735 - aclocal now scans configure.ac for macro definitions (PR/319).
1737 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1738 distributes files which are outside itself (this usually occurs
1739 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1740 from a parent package), then `make distcheck' fails due to an
1741 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1742 (tests/subpkg2.test failure)
1744 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1745 In a VPATH-build configuration, `make install' would install
1746 nobase_ files to wrong locations.
1748 - Fix a Perl `uninitialized value' diagnostic occurring when
1749 automake complains that a Texinfo file does not have a
1750 @setfilename statement.
1752 - Erase config.status.lineno during `make distclean'. This file
1753 can be created by config.status. Automake already knew about
1754 configure.lineno, but forgot config.status.lineno.
1756 - Distribute all files, even those which are built and installed
1757 conditionally. This change affects files listed in conditionally
1758 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1759 as well as those listed in conditionally defined dist_*_DATA,
1760 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1762 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1763 doesn't conform to POSIX.
1765 - Normalize help strings for configure variables and options added
1770 - Check for python2.4 in AM_PATH_PYTHON.
1772 * Spurious failures in test suite:
1774 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1775 tests/ltconv.test: fix failures with CVS Libtool.
1776 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1777 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1778 fix failures with old Texinfo versions.
1780 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1786 - The NEWS file is more verbose.
1790 - Autoconf 2.58 or greater is required.
1794 - Default source file names in the absence of a _SOURCES declaration
1795 are made by removing any target extension before appending `.c', so
1796 to make the libtool module `foo.la' from `foo.c', you only need to
1799 lib_LTLIBRARIES = foo.la
1800 foo_la_LDFLAGS = -module
1802 For backward compatibility, foo_la.c will be used instead of
1803 foo.c if this file exists or is the explicit target of a rule.
1804 However -Wobsolete will warn about this deprecated naming.
1806 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1807 of being hard-coded in each $(AR) invocation, so they can be
1808 substituted from configure.ac. This has been requested by people
1809 dealing with non-POSIX ar implementations.
1811 - New warning option: -Woverride. This will warn about any user
1812 target or variable definitions which override Automake
1815 - Texinfo rules back up and restore info files when makeinfo fails.
1817 - Texinfo rules now support the `html' target.
1818 Running this requires Texinfo 4.0 or greater.
1820 `html' is a new recursive target, so if your package mixes
1821 hand-crafted `Makefile.in's with Automake-generated
1822 `Makefile.in's, you should adjust the former to support (or
1823 ignore) this target so that `make html' recurses successfully. If
1824 you had a custom `html' rule in your `Makefile.am', it's better to
1825 rename it as `html-local', otherwise your rule will override
1826 Automake's new rule (you can check that by running `automake
1827 -Woverride') and that will stop the recursion to subdirectories.
1829 Last but not least, this `html' rule is declared PHONY, even when
1830 overridden. Fortunately, it appears that few packages use a
1831 non-PHONY `html' rule.
1833 - Any file which is m4_included from configure.ac will appear as a
1834 configure and Makefile.in dependency, and will be automatically
1837 - The rules for rebuilding Makefiles and Makefile.ins will now
1838 rebuild all Makefiles and all Makefile.ins at once when one of
1839 configure's dependencies has changed. This is considerably faster
1840 than previous implementations, where config.status and automake
1841 were run separately in each directory (this still happens when you
1842 change a Makefile.am locally, without touching configure.ac or
1843 friends). Doing this also solves a longstanding issue: these
1844 rebuild rules failed to work when adding new directories to the
1845 tree, forcing you to run automake manually.
1847 - For similar reasons, the rules to rebuild configure,
1848 config.status, and aclocal.m4 are now defined in all directories.
1849 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1850 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1851 should better define them in all directories. This is easily done
1852 using an AC_SUBST (make sure you prefix these dependencies with
1853 $(top_srcdir) since this variable will appear at different
1854 levels of the build tree).
1856 - aclocal will now use `m4_include' instead of copying local m4
1857 files into aclocal.m4. (Local m4 files are those you ship with
1858 your project, other files will be copied as usual.)
1860 Because m4_included files are automatically distributed, it means
1861 for most projects there is no point in EXTRA_DISTing the list of
1862 m4 files which are used. (You can probably get rid of
1863 m4/Makefile.am if you had one.)
1865 - aclocal will avoid touching aclocal.m4 when possible, so that
1866 Autom4te's cache isn't needlessly invalidated. This behavior can
1867 be switched off with the new `--force' option.
1869 - aclocal now uses Autoconf's --trace to detect macros which are
1870 actually used and will no longer include unused macros simply
1871 because they where mentioned. This was often the case for macros
1872 called conditionally.
1874 - New options no-dist and no-dist-gzip.
1876 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1877 py-compile, and ylwrap, now all understand --version and --help.
1879 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1880 links as part of the distclean target and including source files in
1883 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1884 argument. The latter can be used to override the default behavior
1885 (which is to abort).
1887 - Automake will exit with $? = 63 on version mismatch. (So does
1888 Autoconf 2.58) missing knows this, and in this case it will
1889 emulate the tools as if they were absent. Because older versions
1890 of Automake and Autoconf did not use this exit code, this change
1891 will only be useful in projects generated with future versions of
1894 - When using AC_CONFIG_FILES with multiple input files, Automake
1895 generates the first ".in" input file for which a ".am" exists.
1896 (Former versions would try to use only the first input file.)
1898 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1899 idiom to disable byte-compilation of lisp_LISP files, it is
1900 recommended that you switch to using lisp_DATA. Note that
1901 this is not strictly equivalent: lisp_DATA will install elisp
1902 files even if emacs is not installed, while *_LISP do not
1903 install anything unless emacs is found.
1905 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1906 available. This selection is achieved through the Makefile
1907 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1908 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1909 `$(install_sh) -m 0755 -d'.
1913 - Because `mkdir -p' is available on most platforms, and we can use
1914 `install-sh -d' when it is not, the use of the mkinstalldirs
1915 script is being phased out. `automake --add-missing' no longer
1916 installs it, and if you remove mkinstalldirs from your package,
1917 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1919 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1920 gettextize and autopoint will install it when needed. Automake
1921 will continue to define the $(mkinstalldirs) and to distribute
1922 mkinstalldirs when this script is in the source tree.
1924 - AM_PROG_CC_STDC is now empty. The content of this macro was
1925 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1926 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1927 renaming should be safe, even if you have to support several,
1928 versions of Automake, because AC_PROG_CC defines this variable
1929 since Autoconf 2.54.)
1931 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1932 variable to override the aclocal.m4 dependencies computed
1933 (inaccurately) by older versions of Automake. Because Automake
1934 now tracks configure's m4 dependencies accurately (see m4_include
1935 above), the use of ACLOCAL_M4_SOURCES should be considered
1936 obsolete and will be flagged as such when running `automake
1941 - Defining programs conditionally using Automake conditionals no
1942 longer leads to a combinatorial explosion. The following
1943 construct used to be troublesome when used with dozens of
1958 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1960 - Due to implementation constraints, previous versions of Automake
1961 proscribed multiple conditional definitions of some variables
1971 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1972 This restriction has been lifted, and these variables now
1973 support multiple conditional definitions as do other variables.
1975 - Cleanup the definitions of $(distdir) and $(top_distdir).
1976 $(top_distdir) now points to the root of the distribution
1977 directory created during `make dist', as it did in Automake 1.4,
1978 not to the root of the build tree as it did in intervening
1979 versions. Furthermore these two variables are now only defined in
1980 the top level Makefile, and passed to sub-directories when running
1983 - The --no-force option now correctly checks the Makefile.in's
1984 dependencies before deciding not to update it.
1986 - Do not assume that make files are called Makefile in cleaning rules.
1988 - Update .info files in the source tree, not in the build tree. This
1989 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1990 used to update these files in the build tree (previous versions did
1991 it in the source tree too), and it caused several problems, varying
1992 from mere annoyance to portability issues.
1994 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1995 when --add-missing and --force-missing are used. For backward
1996 compatibility --add-missing will continue to install COPYING (in
1997 `gnu' strictness) when none of these three files exist, but this
1998 use is deprecated: you should better choose a license yourself and
1999 install it once for all in your source tree (and in your code
2002 - Fix ylwrap so that it does not overwrite header files that haven't
2003 changed, as the inline rule already does.
2005 - User-defined rules override automake-defined rules for the same
2006 targets, even when rules do not have commands. This is not new
2007 (and was documented), however some of the automake-generated
2008 rules have escaped this principle in former Automake versions.
2009 Rules for the following targets are affected by this fix:
2011 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
2012 info, info-am, install-data-am, install-exec-am, install-info,
2013 install-info-am, install-man, installcheck-am, maintainer-clean,
2014 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
2015 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
2017 Practically it means that an attempt to supplement the dependencies
2018 of some target, as in
2020 clean: my-clean-rule
2022 will now *silently override* the automake definition of the
2023 rule for this target. Running `automake -Woverride' will diagnose
2024 all such overriding definitions.
2026 It should be noted that almost all of these targets support a *-local
2027 variant that is meant to supplement the automake-defined rule
2028 (See node `Extending' in the manual). The above rule should
2031 clean-local: my-clean-rule
2033 These *-local targets have been documented since at least
2034 Automake 1.2, so you should not fear the change if you have
2035 to support multiple automake versions.
2039 - The Automake manual is now distributed under the terms of the GNU FDL.
2041 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
2043 - core dumps are no longer removed by the cleaning rules. There are
2044 at least three reasons for this:
2045 1. These files should not be created by any build step,
2046 so their removal do not fit any of the cleaning rules.
2047 Actually, they may be precious to the developer.
2048 2. If such file is created during a build, then it's clearly a
2049 bug Automake should not hide. Not removing the file will
2050 cause `make distcheck' to complain about its presence.
2051 3. Operating systems have different naming conventions for
2052 core dump files. A core file on one system might be a
2053 completely legitimate data file on another system.
2055 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
2056 defined by Automake. This means that any definition in the
2057 environment will be used, unless overridden in the Makefile.am or
2058 on the command line. The old behavior, where these variables were
2059 defined empty in each Makefile, can be obtained by AC_SUBSTing or
2060 AC_ARG_VARing each variable from configure.ac.
2062 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
2063 documented. (The is not a new feature, these variables have
2064 been there since at least Automake 1.4.)
2066 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2068 Bugs fixed in 1.7.9:
2069 * Fix install-strip to work with nobase_ binaries.
2070 * Fix renaming of #line directives in ylwrap.
2071 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
2073 Bugs fixed in 1.7.8:
2074 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
2075 * Fix detection of Debian's install-info, broken since version 1.5.
2076 (Debian bug #213524).
2077 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
2078 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
2080 Bugs fixed in 1.7.7:
2081 * The implementation of automake's --no-force option is unreliable,
2082 so this option is ignored in this version. A real fix will appear in
2083 Automake 1.8. (Debian Bug #206299)
2084 * AM_PATH_PYTHON: really check the whole list of interpreters if no
2085 argument is given. (PR/399)
2086 * Do not warn about leading `_' in variable names, even with -Wportability.
2087 * Support user redefinitions of TEXINFO_TEX.
2088 * depcomp: support AIX Compiler version 6.
2089 * Fix missing rebuilds during `make dist' with BSD make.
2090 (Could produce tarballs containing out-of-date files.)
2091 * Resurrect multilib support.
2092 * Noteworthy manual updates:
2093 - Extending aclocal: how to write m4 macros that won't trigger warnings
2095 - A Shared Library: Rewrite and split into subsections.
2097 Bugs fixed in 1.7.6:
2098 * Fix depcomp's icc mode for ICC 7.1.
2099 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
2100 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
2101 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
2102 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
2103 * Remove Latin-1 characters from elisp-comp.
2104 * Update the manual's @dircategory to match the Free Software Directory.
2106 Bugs fixed in 1.7.5:
2107 * Update install-sh's license to remove an advertising clause.
2108 (Debian bug #191717)
2109 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
2110 that caused invalid Makefile.ins to be generated.
2111 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
2112 * New FAQ entry: renamed objects.
2114 Bugs fixed in 1.7.4:
2115 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
2116 the Emacs implementation)
2117 * Fix output of aclocal.m4 dependencies in subdirectories.
2118 * Use `mv -f' instead of `mv' in fastdep rules.
2119 * Upgrade mdate-sh to work on OS/2.
2120 * Don't byte-compile elisp files when ELCFILES is set empty.
2121 (this documented feature was broken by 1.7.3)
2122 * Diagnose trailing backslashes on last line of Makefile.am.
2123 * Diagnose whitespace following trailing backslashes.

2127 * `make install' will build `BUILT_SOURCES' first.
2128 * Minor documentation fixes.
2130 Bugs fixed in 1.7.3:
2131 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
2132 * Query distutils for `pythondir' and `pythonexecdir', instead of
2133 using an hardcoded path. This should allow builds on 64-bit
2134 distributions that usually use lib64/ instead of lib/.
2135 * AM_PATH_PYTHON will also search for python2.3.
2136 * elisp files are now built all at once instead of one by one. Besides
2137 incurring a speed-up, this is required to support interdependent elisp files.
2138 * Support for DJGPP:
2139 - `make distcheck' will now work in `_inst/' and `_build' instead
2140 of `=inst/' and `=build/'
2141 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
2142 - install/uninstall `*.i[0-9][0-9]'-style info files
2143 - more changes that affect only the Automake package (not its output)
2144 * Fix some incompatibilities with upcoming perl-5.10.
2145 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
2146 PACKAGE and VERSION.
2148 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
2149 is troublesome with gcc and Solaris compilers. (PR/385)
2150 - makedepend mode: work with Libtool. (PR/385 too)
2152 * better support for unusual gettext setups, such as multiple po/ directories
2154 - Flag missing po/ and intl/ directories as warnings, not errors.
2155 - Disable these warnings if po/ does not exist.
2156 * Noteworthy manual updates:
2158 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
2160 - Document `AM_YFLAGS = -d'. (PR/382)
2162 Bugs fixed in 1.7.2:
2163 * Fix installation and uninstallation of Info files built in subdirectories.
2164 * Do not run `./configure --with-included-gettext' during `make distcheck'
2165 if AM_GNU_GETTEXT([external]) is used.
2166 * Correctly uninstall renamed man pages.
2167 * Do not strip escaped newline in variables defined in one condition
2168 and augmented in another condition.
2169 * Fix ansi2knr rules for LIBOBJS sources.
2170 * Clean all known Texinfo index files, not only those which appear to
2171 be used, because we cannot know which indexes are used in included files.
2172 (PR/375, Debian Bug #168671)
2173 * Honor only the first @setfilename seen in a Texinfo file.
2174 * Treat "required file X not found" diagnostics as errors (exit status 1).
2175 * Don't complain that a required file is not found when it is a Makefile
2177 * Don't use single suffix inference rules when building `.info'-less
2178 Info files, for the sake of Solaris make.
2179 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
2180 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
2181 * Warn about multiple inference rules when -Wportability is used. (PR/372)
2182 * Fix building of deansified files from subdirectories. (PR/370)
2183 * Add missing `fi' in the .c->.obj rules.
2184 * Improve install-sh to work even when names contain spaces or certain
2185 (but not all) shell metachars.
2186 * Fix the following spurious failures in the test suite:
2187 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
2188 * Noteworthy manual updates:
2189 - Augment the section about BUILT_SOURCES.
2190 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
2192 Bugs fixed in 1.7.1:
2193 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
2195 * Aclocal should now recognize macro names containing parentheses, e.g.
2196 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
2197 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
2199 * Install Python files even if they were built. (PR/369)
2200 * Have stamp-vti dependent upon configure instead of configure.ac, as the
2201 version might not be defined in the latter. (PR/358)
2202 * Reorder arguments passed to a couple of commands, so things works
2203 when POSIXLY_CORRECT=1.
2204 * Fix a regex that can cause Perl to segfault on large input.
2206 * Fix distribution of packages that have some sources defined conditionally,
2207 as in the `Conditional compilation using Automake conditionals' example
2209 * Fix spurious test suite failures on IRIX.
2210 * Don't report a required variable as undefined if it has been
2211 defined conditionally for the "right" conditions.
2212 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
2213 `make distcheck' fails.
2214 * Fix distribution of included Makefile fragment, so we don't create
2215 spurious directories in the distribution. (PR/366)
2216 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
2219 * Autoconf 2.54 is required.
2220 * `aclocal' and `automake' will no longer warn about obsolete
2221 configure macros. This is done by `autoconf -Wobsolete'.
2222 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
2223 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
2224 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
2225 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
2226 `configure.ac' for you.
2227 * Support for per-program and per-library `_CPPFLAGS'.
2228 * New `ctags' target (builds CTAGS files).
2229 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
2230 (see `automake --help' or the manual for a list of them).
2231 * Honor the WARNINGS environment variable.
2232 * Omit the call to depcomp when using gcc3: call the compiler directly.
2233 * A new option, std-options, tests that programs support --help and --version
2234 when `make installcheck' is run. This is enabled by --gnits.
2235 * Texinfo rules now support the `ps' and `pdf' targets.
2236 * Info files are now created in the build directory, not the source directory.
2237 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
2239 * `make distcheck' will enforce DESTDIR support by attempting
2241 * `+=' can be used in conditionals, even if the augmented variable
2242 was defined for another condition.
2243 * Makefile fragments (inserted with `include') are always distributed.
2244 * Use Autoconf's --trace interface to inspect configure.ac and get
2245 a more accurate view of it.
2246 * Add support for extending aclocal's default macro search path
2247 using a `dirlist' file within the aclocal directory.
2248 * automake --output-dir is deprecated.
2249 * The part of the distcheck target that checks whether uninstall actually
2250 removes all installed files has been moved in a separate target,
2251 distuninstallcheck, so it can be overridden easily.
2255 * Support for AM_INIT_GETTEXT([external])
2256 * Bug fixes, including:
2257 - Fix Automake's own `make install' so it works even if `ln' doesn't.
2258 - nobase_ programs and scripts honor --program-transform correctly.
2259 - Erase configure.lineno during `make distclean'.
2260 - Erase YACC and LEX outputs during `make maintainer-clean'.
2263 * Many bug fixes, including:
2264 - Requiring the current version works.
2265 - Fix "$@" portability issues (for Zsh).
2266 - Fix output of dummy dependency files in presence of post-processed
2268 - Don't compute dependencies in background to avoid races with libtool.
2269 - Fix handling of _OBJECTS variables for targets sharing source variables.
2270 - Check dependency mode for Java when AM_PROG_GCJ is used.
2273 * automake --output-dir is deprecated
2274 * Many bug fixes, including:
2275 - Don't choke on AM_LDFLAGS definitions.
2276 - Clean libtool objects from subdirectories.
2277 - Allow configure variables with reserved suffix and unknown prefix
2278 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
2279 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
2282 * Autoconf 2.52 is required.
2283 * automake no longer run libtoolize.
2284 This is the job of autoreconf (from GNU Autoconf).
2285 * `dist' generates all the archive flavors, as did `dist-all'.
2286 * `dist-gzip' generates the Gzip tar file only.
2287 * Combining Automake Makefile conditionals no longer lead to a combinatorial
2288 explosion. Makefile.in's keep a reasonable size.
2289 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
2290 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
2292 * `#line' of Lex and Yacc files are properly set.
2293 * EXTRA_DIST can contain generated directories.
2294 * Support for dot-less extensions in suffix rules.
2295 * The part of the distcheck target that checks whether distclean actually
2296 cleans all built files has been moved in a separate target, distcleancheck,
2297 so it can be overridden easily.
2298 * `make distcheck' will pass additional options defined in
2299 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
2300 * Fixed CDPATH portability problems, in particular for MacOS X.
2301 * Fixed handling of nobase_ targets.
2302 * Fixed support of implicit rules leading to .lo objects.
2303 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
2304 * Added uninstall-hook target
2305 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
2306 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
2307 (Note that "pkgname" is not "tarname", see the manual for details.)
2308 It is also possible to pass a list of global Automake options as
2309 first argument to this new form of AM_INIT_AUTOMAKE.
2310 * Compiler-based assembler is now called `CCAS'; people expected `AS'
2311 to be a real assembler.
2312 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
2313 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
2314 * aclocal and automake are also installed with the version number
2315 appended, and some of the install directory names have changed.
2316 This lets you have multiple versions installed simultaneously.
2317 * Support for parsers and lexers in subdirectories.
2320 * Support for `configure.ac'.
2321 * Support for `else COND', `endif COND' and negated conditions `!COND'.
2322 * `make dist-all' is much faster.
2323 * Allows '@' AC_SUBSTs in macro names.
2324 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
2325 * User-side dependency tracking. Developers no longer need GNU make
2327 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
2328 * Most files are correctly handled if they appear in subdirs
2329 For instance, a _DATA file can appear in a subdir
2330 * GNU tar is no longer required for `make dist'
2331 * Added support for `dist_' and `nodist_' prefixes
2332 * Added support for `nobase_' prefix
2333 * Compiled Java support
2334 * Support for per-executable and per-library compilation flags
2338 * Added support for the Fortran 77 programming language.
2339 * Re-indexed the Automake Texinfo manual.
2340 * Added `AM_FOOFLAGS' variable for each compiler invocation;
2341 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
2342 * Support for latest autoconf, including support for objext
2343 * Can now put `.' in SUBDIRS to control build order
2344 * `include' command and `+=' support for macro assignment
2345 * Dependency tracking no long susceptible to deleted header file problem
2346 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
2351 * Better Cygwin32 support
2352 * Support for suffix rules with _SOURCES variables
2353 * New options `readme-alpha' and `check-news'; Gnits mode sets these
2354 * @LEXLIB@ no longer required when lex source seen
2355 Lex support in `missing', and new lex macro. Update your missing script.
2356 * Built-in support for assembly
2357 * aclocal gives error if `AM_' macro not found
2358 * Passed YFLAGS, not YACCFLAGS, to yacc

2367 * Better DejaGnu support
2368 * Added no-installinfo option
2369 * Added Emacs Lisp support
2370 * Added --no-force option
2371 * Included `aclocal' program
2372 * Automake will now generate rules to regenerate aclocal.m4, if appropriate
2373 * Now uses `AM_' macro names everywhere
2374 * ansi2knr option can have directory prefix (eg `../lib/ansi2knr')
2375 ansi2knr now works correctly on K&R sources
2376 * Better C++, yacc, lex support
2377 * Will compute _DEPENDENCIES variables automatically if not supplied
2378 * Will interpolate $(...) and ${...} when examining contents of a variable
2379 * .deps files now in build directory, not source directory; dependency
2380 handling generally rewritten
2381 * DATA, MANS and BUILT_SOURCES no longer included in distribution
2382 * can now put config.h into a subdir
2383 * Added dist-all target
2384 * Support for install-info program (see texinfo 3.9)
2385 * Support for "yacc -d"
2386 * configure substitutions are automatically discovered and included
2387 in generated Makefile.in
2388 * Special --cygnus mode
2389 * OMIT_DEPENDENCIES can now hold list of dependencies to be omitted
