3 * WARNING: Future backward-incompatibilities!
5 - Future versions of Automake will likely drop support for the
6 long-deprecated 'configure.in' name for the Autoconf input file.
7 You are advised to use the recommended name 'configure.ac' instead.
9 - The long-obsolete (since automake 1.10) AM_PROG_MKDIR m4 macro will
10 be removed in Automake 1.13. The $(mkdir_p) make variable and the
11 @mkdir_p@ substitution will still remain available (as aliases of
12 $(MKDIR_P)) for the moment, for better backward compatibility.
14 - Autoconf 2.65 or later will be required by the next major Automake
15 version (1.13). Until now, Automake has required Autoconf version
18 - Starting from the next major Automake version (1.13), the rules
19 to build pdf, ps and dvi output from Texinfo input will use the
20 '--build-dir' option by default. Since such an option was only
21 introduced in Texinfo 4.9, this means that Makefiles generated by
22 future Automake versions will require at least that version of
25 - Starting from the next major Automake version (1.13), the parallel
26 testsuite harness (previously only enabled by the 'parallel-tests'
27 option) will become the default one; the older serial testsuite
28 harness will still be available through the use of the 'serial-tests'
31 - The following long-obsolete m4 macros will be removed in the
32 next major Automake version (1.13):
34 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
35 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
36 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
37 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
38 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
39 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
40 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
41 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
42 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
43 of the now-removed automatic de-ANSI-fication
46 - All the "old alias" macros in 'm4/obsolete.m4' will be removed in
47 the next major Automake version (1.13).
49 - Support for the two- and three-arguments invocation forms of the
50 AM_INIT_AUTOMAKE macro is deprecated, and will be removed in the
51 next major Automake version (1.13).
53 - The '--acdir' option of aclocal is deprecated, and will probably
54 be removed in the next major Automake release (1.13). You should
55 use the options '--automake-acdir' and '--system-acdir' instead
56 (which have been introduced in Automake 1.11.2).
58 - The exact order in which the directories in the aclocal macro
59 search path are looked up is probably going to be changed in the
60 next Automake release (1.13).
62 - The 'missing' script will not try anymore to update the timestamp
63 of out-of-date files that require a maintainer-specific tool to be
64 remade, in case the user lacks such a tool (or has a too-old version
65 of it). In fact, starting from Automake 1.13, all it'll do will be
66 giving more useful warnings than a bare "command not found" from a
69 * Warnings and deprecations:
71 - Warnings in the 'obsolete' category are enabled by default both in
74 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
78 * Miscellaneous changes:
80 - The '.m4' files provided by Automake does not define serial numbers
81 anymore. This should cause no difference in the behaviour of aclocal
84 - Some testsuite weaknesses and spurious failures have been fixed.
86 - There is initial support for automatic dependency tracking with the
87 Portland Group C/C++ compilers, thanks to the new new depmode 'pgcc'.
93 - Instead of renaming only self-references of files (typically for
94 #lines), ylwrap now also renames references to the other generated
95 files. This fixes support for GLR and C++ parsers from Bison (PR
96 automake/491 and automake bug#7648): 'parser.c' now properly
97 #includes 'parser.h' instead of 'y.tab.h'.
99 - Generated files unknown to ylwrap are now preserved. This fixes
100 C++ support for Bison (automake bug#7648): location.hh and the
101 like are no longer discarded.
103 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
107 * Warnings and deprecations:
109 - Automake now issues a warning (in the 'portability' category) if
110 'configure.in' is used instead of 'configure.ac' as the Autoconf
111 input file. Such a warning will also be present in the next
112 Autoconf version (2.70).
116 - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
117 order (as done by the other recursive rules), rather than in the
118 inverse order. They used to do that in order to work a round a
119 limitation in an older implementation of the automatic dependency
120 tracking support, but that limitation had been lifted years ago
121 already, when the automatic dependency tracking based on side-effects
122 of compilation had been introduced.
124 - Cleaning rules for compiled objects (both "plain" and libtool) work
125 better when subdir objects are involved, not triggering a distinct
126 'rm' invocation for each such object. They do so by removing *any*
127 compiled object file that is in the same directory of a subdir
128 object. See automake bug#10697.
130 * Silent rules support:
132 - A new predefined $(AM_V_P) make variable is provided; it expands
133 to a shell conditional that can be used in recipes to know whether
134 make is being run in silent or verbose mode.
136 Bugs fixed in 1.12.2:
138 * SECURITY VULNERABILITIES!
140 - The 'distcheck' recipe no longer grants temporary world-write
141 permissions on the extracted distdir. Even if such rights were
142 only granted for a vanishingly small time window, the implied
143 race condition proved to be enough to allow a local attacker
144 to run arbitrary code with the privileges of the user running
145 "make distcheck". This is CVE-2012-3386.
147 * Long-standing bugs:
149 - The "recheck" targets behaves better in the face of build failures
150 related to previously failed tests. For example, if a test is a
151 compiled program that must be rerun by "make recheck", and its
152 compilation fails, it will still be rerun by further "make recheck"
153 invocations. See automake bug#11791.
155 * Bugs introduced by 1.12.1:
157 - Automake provides once again the '$(mkdir_p)' make variable and the
158 '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
159 for better backward-compatibility.
161 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
165 * New supported languages:
167 - Support for Objective C++ has been added; it should work similarly to
168 the support for Objective C.
170 * Deprecated obsolescent features:
172 - Use of the long-deprecated two- and three-arguments invocation forms
173 of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
174 category. Starting from the next major Automake release (1.13), such
175 usages won't be allowed anymore.
177 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
178 now deprecated (its use triggers a warning in the 'obsolete' category).
179 It will be removed in the next major Automake release (1.13).
181 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
182 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
183 m4 macro are deprecated, eliciting a warning in the 'obsolete'
186 * Miscellaneous changes:
188 - The Automake test cases now require a proper POSIX-conforming shell.
189 Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) won't be
190 accepted anymore. In most cases, the user shouldn't have to specify
191 such POSIX shell explicitly, since it will be looked up at configure
192 time. Still, when this lookup fails, or when the user wants to
193 override its conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be
194 used (pointing to the shell that will be used to run the Automake
197 Bugs fixed in 1.12.1:
199 * Bugs introduced by 1.12:
201 - Several weaknesses in Automake's own build system and test suite
204 * Bugs introduced by 1.11.3:
206 - When given non-option arguments, aclocal rejects them, instead of
207 silently ignoring them.
209 * Long-standing bugs:
211 - When the 'color-tests' option is in use, forcing of colored testsuite
212 output through "AM_COLOR_TESTS=always" works even if the terminal is
213 a non-ANSI one, i.e., if the TERM environment variable has a value of
216 - Several inefficiencies and poor performances in the implementation
217 of the parallel-tests 'check' and 'recheck' targets have been fixed.
219 - The post-processing of output "#line" directives done the ylwrap
220 script is more faithful w.r.t. files in a subdirectory; for example,
221 if the processed file is "src/grammar.y", ylwrap will correctly
222 produce directives like:
223 #line 7 "src/grammar.y"
228 * Bugs with new Perl versions:
230 - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
232 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
236 * Obsolete features removed:
238 - The never documented nor truly used script 'acinstall' has been
241 - Support for automatic de-ANSI-fication has been removed.
243 - The support for the "obscure" multilib feature has been removed
244 from Automake core (but remains available in the 'contrib/'
245 directory of the Automake distribution).
247 - Support for ".log -> .html" conversion and the check-html and
248 recheck-html targets has been removed from Automake core (but
249 remains available in the 'contrib/' directory of the Automake
252 - The deprecated 'lzma' compression format for distribution archives
253 has been removed, in favor of 'xz' and 'lzip'.
255 - The obsolete AM_WITH_REGEX macro has been removed.
257 - The long-deprecated options '--output-dir', '--Werror' and
258 '--Wno-error' have been removed.
260 - The chapter on the history of Automake has been moved out of the
261 reference manual, into a new dedicated Texinfo file.
265 - New 'cscope' target to build a cscope database for the source tree.
267 * Changes to Automake-generated testsuite harnesses:
269 - The new automake option 'serial-tests' has been introduced. It can
270 be used to explicitly instruct automake to use the older serial
271 testsuite harness. This is still the default at the moment, but it
272 might change in future versions.
274 - The 'recheck' target (provided by the parallel testsuite harness) now
275 depends on the 'all' target. This allows for a better user-experience
276 in test-driven development. See automake bug#11252.
278 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
279 and unexpected or internal error, or a failure to set up the test case
280 scenario) have their outcome reported as an 'ERROR' now. Previous
281 versions of automake reported such an outcome as a 'FAIL' (the only
282 difference with normal failures being that hard errors were counted
283 as failures even when the test originating them was listed in
286 - The testsuite summary displayed by the parallel-test harness has a
287 completely new format, that always list the numbers of passed, failed,
288 xfailed, xpassed, skipped and errored tests, even when these numbers
289 are zero (but using smart coloring when the color-tests option is in
292 - The default testsuite driver offered by the 'parallel-tests' option is
293 now implemented (partly at least) with the help of automake-provided
294 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
295 on code in the generated Makefile.in.
296 This has two noteworthy implications. The first one is that projects
297 using the 'parallel-tests' option should now either run automake with
298 the '--add-missing' option, or manually copy the 'test-driver' script
299 into their tree. The second, and more important, implication is that
300 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
301 not be used anymore to define a test runner, and the command specified
302 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
303 program or script. For example, this is still a valid usage (albeit
306 TESTS_ENVIRONMENT = \
307 if test -n '$(STRICT_TESTS)'; then \
308 maybe_errexit='-e'; \
312 LOG_COMPILER = $(SHELL) $$maybe_errexit
314 while this is not anymore:
316 TESTS_ENVIRONMENT = \
317 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
321 TESTS_ENVIRONMENT = \
322 run_with_perl_or_shell () \
324 if grep -q '^#!.*perl' $$1; then
330 LOG_COMPILER = run_with_perl_or_shell
332 - The package authors can now use customary testsuite drivers within
333 the framework provided by the 'parallel-tests' testsuite harness.
334 Consistently with the existing syntax, this can be done by defining
335 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
337 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
338 to redirect/define file descriptors used by the test scripts.
340 - The parallel-tests harness generates now, in addition the '.log' files
341 holding the output produced by the test scripts, a new set of '.trs'
342 files, holding "metadata" derived by the execution of the test scripts;
343 among such metadata are the outcomes of the test cases run by a script.
345 - Initial and still experimental support for the TAP test protocol is
348 * Changes to Yacc and Lex support:
350 - C source and header files derived from non-distributed Yacc and/or
351 Lex sources are now removed by a simple "make clean" (while they were
352 previously removed only by "make maintainer-clean").
354 - Slightly backward-incompatible change, relevant only for use of Yacc
355 with C++: the extensions of the header files produced by the Yacc
356 rules are now modelled after the extension of the corresponding
357 sources. For example, yacc files named "foo.y++" and "bar.yy" will
358 produce header files named "foo.h++" and "bar.hh" respectively, where
359 they would have previously produced header files named simply "foo.h"
360 and "bar.h". This change offers better compatibility with 'bison -o'.
362 * Miscellaneous changes:
364 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
365 rather than 1, if the vala compiler found is too old.
367 - The build system of Automake itself now avoids the use of make
368 recursion as much as possible.
370 - Automake now prefers to quote 'like this' or "like this", rather
371 than `like this', in diagnostic message and generated Makefiles,
372 to accommodate the new GNU Coding Standards recommendations.
374 - Automake has a new option '--print-libdir' that prints the path of the
375 directory containing the Automake-provided scripts and data files.
377 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
379 - The rules to create pdf, dvi and ps output from Texinfo files now
380 works better with modern 'texi2dvi' script, by explicitly passing
381 it the '--clean' option to ensure stray auxiliary files are not
382 left to clutter the build directory.
384 - Automake can now generate silenced rules for texinfo outputs.
386 - Some auxiliary files that are automatically distributed by Automake
387 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
388 C sources) might now be listed in the DIST_COMMON variable in many
389 Makefile.in files, rather than in the top-level one.
391 - Messages of types warning or error from 'automake' and 'aclocal'
392 are now prefixed with the respective type, and presence of -Werror
395 - Automake's early configure-time sanity check now tries to avoid
396 sleeping for a second, which slowed down cached configure runs
397 noticeably. In that case, it will check back at the end of the
398 configure script to ensure that at least one second has passed, to
399 avoid time stamp issues with makefile rules rerunning autotools
402 - The warnings in the category 'extra-portability' are now enabled by
403 '-Wall'. In previous versions, one has to use '-Wextra-portability'
408 - Various minor bugfixes for recent or long-standing bugs.
410 * Bugs introduced by 1.11:
412 - The AM_COND_IF macro also works if the shell expression for the
413 conditional is no longer valid for the condition.
415 - The automake-provided parallel testsuite harness does not fail anymore
416 with BSD make used in parallel mode when there are test scripts in a
417 subdirectory, like in:
419 TESTS = sub/foo.test sub/bar.test
421 * Long-standing bugs:
423 - Automake's own build system finally have a real "installcheck" target.
425 - Vala-related cleanup rules are now more complete, and work better in
428 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
429 now automatically distributed also if the directory of the auxiliary
430 files coincides with the top-level directory.
432 - Automake now detects the presence of the '-d' flag in the various
433 '*YFLAGS' variables even when their definitions involve indirections
434 through other variables, such as in:
436 AM_YFLAGS = $(foo_opts)
438 - Automake now complains if a '*YFLAGS' variable has any conditional
439 content, not only a conditional definition.
441 - Explicit enabling and/or disabling of Automake warning categories
442 through the '-W...' options now always takes precedence over the
443 implicit warning level implied by Automake strictness (foreign, gnu
444 or gnits), regardless of the order in which such strictness and
445 warning flags appear. For example, a setting like:
446 AUTOMAKE_OPTIONS = -Wall --foreign
447 will cause the warnings in category 'portability' to be enabled, even
448 if those warnings are by default disabled in 'foreign' strictness.
450 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
452 Bugs fixed in 1.11.5:
454 * Bugs introduced by 1.11.3:
456 - Vala files with '.vapi' extension are now recognized and handled
457 correctly again. See automake bug#11222.
459 - Vala support work again for projects that contain some program
460 built from '.vala' (and possibly '.c') sources and some other
461 program built from '.c' sources *only*. See automake bug#11229.
463 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
467 * Miscellaneous changes:
469 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
470 symbol index) modifiers as well as the "s" action, as the symbol index
471 is created unconditionally by Microsoft lib. Also, the "q" (quick)
472 action is now a synonym for "r" (replace). Also, the script has been
473 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
475 - When the 'compile' script is used to wrap MSVC, it now accepts an
476 optional space between the -I, -L and -l options and their respective
477 arguments, for better POSIX compliance.
479 - There is an initial, experimental support for automatic dependency
480 tracking with tcc (the Tiny C Compiler). Its associated depmode is
481 currently recognized as "icc" (but this and other details are likely
482 to change in future versions).
484 - Automatic dependency tracking now works also with the IBM XL C/C++
485 compilers, thanks to the new new depmode 'xlc'.
487 Bugs fixed in 1.11.4:
489 * Bugs introduced by 1.11.2:
491 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
492 don't cause spurious failures upon "make install" anymore.
494 - The user can now instruct the 'uninstall-info' rule not to update
495 the '${infodir}/dir' file by exporting the environment variable
496 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
497 with how the 'install-info' rule operates since automake 1.11.2.
499 * Long-standing bugs:
501 - It is now possible for a foo_SOURCES variable to hold Vala sources
502 together with C header files, as well as with sources and headers for
503 other supported languages (e.g., C++). Previously, only mixing C and
504 Vala sources was supported.
506 - If "aclocal --install" is used, and the first directory specified with
507 '-I' is non-existent, aclocal will now create it before trying to copy
510 - An empty declaration of a "foo_PRIMARY" don't cause anymore the
511 generated install rules to create an empty $(foodir) directory;
512 for example, if Makefile.am contains something like:
516 pkglibexec_SCRIPTS += bar.sh
519 the $(pkglibexec) directory will not be created upon "make install".
521 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
525 * Miscellaneous changes:
527 - Automake's own build system is more silent by default, making use of
528 the 'silent-rules' option.
530 - The master copy of the `gnupload' script is now maintained in gnulib,
533 - The `missing' script doesn't try to wrap calls to `tar' anymore.
535 - "make dist" doesn't wrap `tar' invocations with the `missing' script
536 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
537 shouldn't be using BTW ;-) does not invoke the missing script anymore
538 to wrap tar, but simply invokes the `tar' program itself.
540 - "make dist" can now create lzip-compressed tarballs.
542 - In the Automake info documentation, the Top node and the nodes about
543 the invocation of the automake and aclocal programs have been renamed;
544 now, calling "info automake" will open the Top node, while calling
545 "info automake-invocation" and "info aclocal-invocation" will access
546 the nodes about the invocation of respectively automake and aclocal.
548 - Automake is now distributed as a gzip-compressed and an xz-compressed
549 tarball. Previously, bzip2 was used instead of xz.
551 - The last relics of Python 1.5 support have been removed from the
552 AM_PATH_PYTHON macro.
554 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
555 and adds them to the normal list of dependencies, but without
556 overwriting the foo_DEPENDENCIES variable, which is normally computed
559 Bugs fixed in 1.11.3:
561 * Bugs introduced by 1.11.2:
563 - Automake now correctly recognizes the prefix/primary combination
564 `pkglibexec_SCRIPTS' as valid.
566 - The parallel-tests harness doesn't trip anymore on sed implementations
567 with stricter limits on the length of input lines (problem seen at
570 * Long-standing bugs:
572 - The "deleted header file problem" for *.am files is avoided by stub
573 rules. This allows `make' to trigger a rerun of `automake' also if
574 some previously needed `.am' file has been removed.
576 - The `silent-rules' option now generates working makefiles even
577 for the uncommon `make' implementations that do not support the
578 nested-variables extension to POSIX 2008. For such `make'
579 implementations, whether a build is silent is determined at
580 configure time, and cannot be overridden at make time with
581 `make V=0' or `make V=1'.
583 - Vala support now works better in VPATH setups.
585 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
589 * Changes to aclocal:
591 - The `--acdir' option is deprecated. Now you should use the new options
592 `--automake-acdir' and `--system-acdir' instead.
594 - The `ACLOCAL_PATH' environment variable is now interpreted as a
595 colon-separated list of additional directories to search after the
596 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
597 and before the system acdir (by default ${prefix}/share/aclocal).
599 * Miscellaneous changes:
601 - The Automake support for automatic de-ANSI-fication has been
602 deprecated. It will probably be removed in the next major Automake
605 - The `lzma' compression scheme and associated automake option `dist-lzma'
606 is obsoleted by `xz' and `dist-xz' due to upstream changes.
608 - You may adjust the compression options used in dist-xz and dist-bzip2.
609 The default is now merely -e for xz, but still -9 for bzip; you may
610 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
611 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
613 - The `compile' script now converts some options for MSVC for a better
614 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
616 - The py-compile script now accepts empty arguments passed to the options
617 `--destdir' and `--basedir', and complains about unrecognized options.
618 Moreover, a non-option argument or a special `--' argument terminates
621 - A developer that needs to pass specific flags to configure at "make
622 distcheck" time can now, and indeed is advised to, do so by defining
623 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
624 instead of the old DISTCHECK_CONFIGURE_FLAGS.
625 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
626 user; still, the old Makefile.am files that used to define it will
627 still continue to work as before.
629 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
630 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
631 This new macro is required for LIBRARIES and LTLIBRARIES when automake
632 is run with -Wextra-portability and -Werror.
634 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
635 file generated by automake-provided rules by defining the special make
636 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
638 - The `install-info' rule can now be instructed not to create/update
639 the `${infodir}/dir' file, by exporting the new environment variable
640 `AM_UPDATE_INFO_DIR' to the value "no".
642 Bugs fixed in 1.11.2:
644 * Bugs introduced by 1.11:
646 - The parallel-tests driver no longer produces erroneous results with
647 Tru64/OSF 5.1 sh upon unreadable log files.
649 - The `parallel-tests' test driver does not report spurious successes
650 when used with concurrent FreeBSD make (e.g., "make check -j3").
652 - When the parallel-tests driver is in use, automake now explicitly
653 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
654 instead of issuing confusing and apparently unrelated error messages
655 (e.g., "non-POSIX variable name", "bad characters in variable name",
656 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
657 silently producing broken `Makefile.in' files.
659 - The `silent-rules' option now truly silences all compile rules, even
660 when dependency tracking is disabled. Also, when `silent-rules' is
661 not used, `make' output no longer contains spurious backslash-only
662 lines, thus once again matching what Automake did before 1.11.
664 - The AM_COND_IF macro also works if the shell expression for the
665 conditional is no longer valid for the condition.
667 * Long-standing bugs:
669 - The order of Yacc and Lex flags is fixed to be consistent with other
670 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
671 $(LFLAGS), so that the user variables override the developer variables.
673 - "make distcheck" now correctly complains also when "make uninstall"
674 leaves one and only one file installed in $(prefix).
676 - A "make uninstall" issued before a "make install", or after a mere
677 "make install-data" or a mere "make install-exec" does not spuriously
680 - Automake now warns about more primary/directory invalid combinations,
681 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
683 - Rules generated by Automake now try harder to not change any files when
684 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
685 Yacc source files and the rule to update config.h.
687 - Several scripts and the parallel-tests testsuite driver now exit with
688 the right exit status upon receiving a signal.
690 - A per-Makefile.am setting of -Werror does not erroneously carry over
691 to the handling of other Makefile.am files.
693 - The code for automatic dependency tracking works around a Solaris
694 make bug triggered by sources containing repeated slashes when the
695 `subdir-objects' option was used.
697 - The makedepend and hp depmodes now work better with VPATH builds.
699 - Java sources specified with check_JAVA are no longer compiled for
700 "make all", but only for "make check".
702 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
703 and error out if `javadir' is undefined, instead of silently producing
704 a broken Makefile.in.
706 - aclocal and automake now honour the configure-time definitions of
707 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
709 - The `install-info' recipe no longer tries to guess whether the
710 `install-info' program is from Debian or from GNU, and adaptively
711 change its behaviour; this has proven to be frail and easy to
714 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
716 Bugs fixed in 1.11.1:
718 - Lots of minor bugfixes.
720 * Bugs introduced by 1.11:
722 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
723 trailing white space in the test list (`TESTS = foo $(EMPTY)').
725 * Long standing bugs:
727 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
728 even if the `--prefix' argument pointed outside of a system directory.
729 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
730 `get_python_lib' function if it points outside the configured prefix,
731 unless the `--prefix' argument was either `/usr' or below `/System'.
733 - The testsuite does not try to change the mode of `ltmain.sh' files from
734 a Libtool installation (symlinked to test directories) any more.
736 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
737 tools are preferred in a cross-compile setup.
739 - The distribution is tarred up with mode 755 now by the `dist*' targets.
740 This fixes a race condition where untrusted users could modify files
741 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
742 build directory was world-searchable. This is CVE-2009-4029.
744 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
748 * Version requirements:
750 - Autoconf 2.62 or greater is required.
752 * Changes to aclocal:
754 - The autoconf version check implemented by aclocal in aclocal.m4
755 (and new in Automake 1.10) is degraded to a warning. This helps
756 in the common case where the Autoconf versions used are compatible.
758 * Changes to automake:
760 - The automake program can run multiple threads for creating most
761 Makefile.in files concurrently, if at least Perl 5.7.2 is available
762 with interpreter-based threads enabled. Set the environment variable
763 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
764 enable this experimental feature.
766 * Changes to Libtool support:
768 - Libtool generic flags are now passed to the install and uninstall
771 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
772 config.lt is removed correctly now.
776 - subdir-object mode works now with Fortran (F77, FC, preprocessed
777 Fortran, and Ratfor).
779 - For files with extension .f90, .f95, .f03, or .f08, the flag
780 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
782 - Files with extension .sx are also treated as preprocessed assembler.
784 - The default source file extension (.c) can be overridden with
785 AM_DEFAULT_SOURCE_EXT now.
787 - Python 3.0 is supported now, Python releases prior to 2.0 are no
790 - AM_PATH_PYTHON honors python's idea about the site directory.
792 - There is initial support for the Vala programming language, when using
795 * Miscellaneous changes:
797 - Automake development is done in a git repository on Savannah now, see
799 http://git.sv.gnu.org/gitweb/?p=automake.git
801 A read-only CVS mirror is provided at
803 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
804 checkout -d automake HEAD
806 - "make dist" can now create xz-compressed tarballs,
807 as well as (deprecated?) lzma-compressed tarballs.
809 - `automake --add-missing' will by default install the GPLv3 file as
810 COPYING if it is missing. It will also warn that the license file
811 should be added to source control. Note that Automake will never
812 overwrite an existing COPYING file, even when the `--force-missing'
815 - The manual is now distributed under the terms of the GNU FDL 1.3.
817 - Automake ships and installs man pages for automake and aclocal now.
819 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
821 - install-sh supports -C, which does not update the installed file
822 (and its time stamps) if the contents did not change.
824 - The `gnupload' script has been revamped.
826 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
828 - The targets `install' and `uninstall' are more efficient now, in that
829 for example multiple files from one Automake variable such as
830 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
831 invocation if they do not have to be renamed.
833 Both install and uninstall may sometimes enter (`cd' into) the target
834 installation directory now, when no build-local scripts are used.
836 Both install and uninstall do not fail anymore but do nothing if an
837 installation directory variable like `bindir' is set to the empty string.
839 For built-in rules, `make install' now fails reliably if installation
840 of a file failed. Conversely, `make uninstall' even succeeds when
841 issued multiple times.
843 These changes may need some adjustments from users: For example,
844 some `install' programs refuse to install multiple copies of the
845 same file in one invocation, so you may need to remove duplicate
846 entries from file lists.
848 Also, within one set of files, say, nobase_data_DATA, the order of
849 installation may be changed, or even unstable among different hosts,
850 due to the use of associative arrays in awk. The increased use of
851 awk matches a similar move in Autoconf to provide for better scaling.
853 Further, most undocumented per-rule install command variables such as
854 binSCRIPT_INSTALL have been removed because they are not needed any
855 more. Packages which use them should be using the appropriate one of
856 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
857 counterpart, depending on the type of files and the need for automatic
858 target directory creation.
860 - The "deleted header file problem" for *.m4 files is avoided by
861 stub rules. This allows `make' to trigger a rerun of `aclocal'
862 also if some previously needed macro file has been removed.
864 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
865 an otherwise up to date tree.
867 - The `color-tests' option causes colored test result output on terminals.
869 - The `parallel-tests' option enables a new test driver that allows for
870 parallel test execution, inter-test dependencies, lazy test execution
871 for unit-testing, re-testing only failed tests, and formatted result output
872 as RST (reStructuredText) and HTML. Enabling this option may require some
873 changes to your test suite setup; see the manual for details.
875 - The `silent-rules' option enables Linux kernel-style silent build output.
876 This option requires the widely supported but non-POSIX `make' feature
877 of recursive variable expansion, so do not use it if your package needs
878 to build with `make' implementations that do not support it.
880 To enable less verbose build output, the developer has to use the Automake
881 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
882 macro. The user may then set the default verbosity by passing the
883 `--enable-silent-rules' option to `configure'. At `make' run time, this
884 default may be overridden using `make V=0' for less verbose, and `make V=1'
885 for backward-compatible verbose output.
887 - New prefix `notrans_' for manpages which should not be transformed
888 by --program-transform.
890 - New macro AM_COND_IF for conditional evaluation and conditional
893 - For AC_CONFIG_LINKS, if source and destination are equal, do not
894 remove the file in a non-VPATH build. Such setups work with Autoconf
897 - AM_MAINTAINER_MODE now allows for an optional argument specifying
900 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
901 useful especially for multi-line values.
903 - Automake's early configure-time sanity check now diagnoses an
904 unsafe absolute source directory name and makes configure fail.
906 - The Automake macros and rules cope better with whitespace in the
907 current directory name, as long as the relative path to `configure'
908 does not contain whitespace. To this end, the values of `$(MISSING)'
909 and `$(install_sh)' may contain suitable quoting, and their expansion
910 might need `eval'uation if used outside of a makefile. These
911 undocumented variables may be used in several documented macros such
912 as $(AUTOCONF) or $(MAKEINFO).
916 * Long-standing bugs:
918 - Fix aix dependency tracking for libtool objects.
920 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
921 unnecessary use of the `compile' script.
923 - For nobase_*_LTLIBRARIES with nonempty directory components, the
924 correct `-rpath' argument is used now.
926 - `config.status --file=Makefile depfiles' now also works with the
927 extra quoting used internally by Autoconf 2.62 and newer
928 (it used to work only without the `--file=' bit).
930 - The `missing' script works better with versioned tool names.
932 - Semantics for `missing help2man' have been revamped:
934 Previously, if `help2man' was not present, `missing help2man' would have
935 the following semantics: if some man page was out of date but present, then
936 a warning would be printed, but the exit status was 0. If the man page was
937 not present at all, then `missing' would create a replacement man page
938 containing an error message, and exit with a status of 2. This does not play
939 well with `make': the next run will see this particular man page as being up
940 to date, and will only error out on the next generated man page, if any;
941 repeat until all pages are done. This was not desirable.
943 These are the new semantics: if some man page is not present, and help2man
944 is not either, then `missing' will warn and generate the replacement page
945 containing the error message, but exit successfully. However, `make dist'
946 will ensure that no such bogus man pages are packaged into a tarball.
948 - Targets provided by automake behave better with `make -n', in that they
949 take care not to create files.
951 - `config.status Makefile... depfiles' works fine again in the presence of
952 disabled dependency tracking.
954 - The default no-op recursive rules for these targets also work with BSD make
955 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
957 - `make distcheck' works also when both a directory and some file below it
958 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
960 - Texinfo dvi, ps, pdf, and html output files are not removed upon
961 `make mostlyclean' any more; only the LaTeX by-products are.
963 - Renamed objects also work with the `subdir-objects' option and
964 source file languages which Automake does not know itself.
966 - `automake' now correctly complains about variable assignments which are
967 preceded by a comment, extend over multiple lines with backslash-escaped
968 newlines, and end in a comment sign. Previous versions would silently
969 and wrongly ignore such assignments completely.
971 * Bugs introduced by 1.10:
973 - Fix output of dummy dependency files in presence of post-processed
974 Makefile.in's again, but also cope with long lines.
976 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
977 that have been declared as programs in the same Makefile.
978 This is for consistency with the analogous change to TESTS in 1.10.
980 - Fix order of standard includes to again be `-I. -I$(srcdir)',
981 followed by directories containing config headers.
983 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
987 * Version requirements:
989 - Autoconf 2.60 or greater is required.
991 - Perl 5.6 or greater is required.
993 * Changes to aclocal:
995 - aclocal now also supports -Wmumble and -Wno-mumble options.
997 - `dirlist' entries (for the aclocal search path) may use shell
998 wildcards such as `*', `?', or `[...]'.
1000 - aclocal supports an --install option that will cause system-wide
1001 third-party macros to be installed in the local directory
1002 specified with the first -I flag. This option also uses #serial
1003 lines in M4 files to upgrade local macros.
1005 The new aclocal options --dry-run and --diff help to review changes
1006 before they are installed.
1008 - aclocal now outputs an autoconf version check in aclocal.m4 in
1009 projects using automake.
1011 For a few years, automake and aclocal have been calling autoconf
1012 (or its underlying engine autom4te) to accurately retrieve the
1013 data they need from configure.ac and its siblings. Doing so can
1014 only work if all autotools use the same version of autoconf. For
1015 instance a Makefile.in generated by automake for one version of
1016 autoconf may stop working if configure is regenerated with another
1017 version of autoconf, and vice versa.
1019 This new version check ensures that the whole build system has
1020 been generated using the same autoconf version.
1022 * Support for new Autoconf macros:
1024 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
1026 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
1027 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
1028 in different directories. However, only one instance of such a
1029 library objects directory is supported.
1031 * Change to Libtool support:
1033 - Libtool generic flags (those that go before the --mode=MODE option)
1034 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
1036 * Yacc and Lex changes:
1038 - The rebuild rules for distributed Yacc and Lex output will avoid
1039 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
1042 - ylwrap is now always used for lex and yacc source files,
1043 regardless of whether there is more than one source per directory.
1045 * Languages changes:
1047 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
1048 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
1049 tracking, unlike non-preprocessed assembler (*.s).
1051 - subdir-object mode works now with Assembler. Automake assumes
1052 that the compiler understands `-c -o'.
1054 - Preprocessed assembler (*.S) compilation now also honors
1055 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
1057 - Improved support for Objective C:
1058 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
1059 - A new section of the manual documents the support.
1061 - New support for Unified Parallel C:
1062 - AM_PROG_UPC looks for a UPC compiler.
1063 - A new section of the manual documents the support.
1065 - Per-target flags are now correctly handled in link rules.
1067 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
1068 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
1069 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
1070 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
1072 The fix for compiler flags (i.e., using maude_CFLAGS instead of
1073 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
1074 is expected to work (and actually works during compilation).
1076 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
1077 "in addition to" breaks backward compatibility with older versions.
1078 If your package used both variables, as in
1080 AM_LDFLAGS = common flags
1081 bin_PROGRAMS = a b c
1082 a_LDFLAGS = more flags
1085 and assumed *_LDFLAGS would sum up, you should rewrite it as
1087 AM_LDFLAGS = common flags
1088 bin_PROGRAMS = a b c
1089 a_LDFLAGS = $(AM_LDFLAGS) more flags
1092 This new behavior of *_LDFLAGS is more coherent with other
1093 per-target variables, and the way *_LDFLAGS variables were
1094 considered internally.
1096 * New installation targets:
1098 - New targets mandated by GNU Coding Standards:
1103 By default they will only install Texinfo manuals.
1104 You can customize them with *-local variants:
1110 - The undocumented recursive target `uninstall-info' no longer exists.
1111 (`uninstall' is in charge of removing all possible documentation
1112 flavors, including optional formats such as dvi, ps, or info even
1113 when `no-installinfo' is used.)
1115 * Miscellaneous changes:
1117 - Automake no longer complains if input files for AC_CONFIG_FILES
1118 are specified using shell variables.
1120 - clean, distribution, or rebuild rules are normally disabled for
1121 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
1122 AC_CONFIG_LINK specified using shell variables. However, if these
1123 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
1124 be able to output rules anyway.
1125 (See the Automake documentation for AC_CONFIG_FILES.)
1127 - $(EXEEXT) is automatically appended to filenames of TESTS
1128 that have been declared as programs in the same Makefile.
1129 This is mostly useful when some check_PROGRAMS are listed in TESTS.
1131 - `-Wportability' has finally been turned on by default for `gnu' and
1132 `gnits' strictness. This means, automake will complain about %-rules
1133 or $(GNU Make functions) unless you switch to `foreign' strictness or
1134 use `-Wno-portability'.
1136 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
1137 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
1138 $(mkdir_p) variable is still defined (to the same value as
1139 $(MKDIR_P)) but should be considered obsolete. If you are using
1140 $(mkdir_p) in some of your rules, please plan to update them to
1141 $(MKDIR_P) at some point.
1143 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
1144 They still work in this release, but may be withdrawn in a future one.
1146 - Inline compilation rules for gcc3-style dependency tracking are
1149 - Automake installs a "Hello World!" example package in $(docdir).
1150 This example is used throughout the new "Autotools Introduction"
1151 chapter of the manual.
1153 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1157 * Makefile.in bloat reduction:
1159 - Inference rules are used to compile sources in subdirectories when
1160 the `subdir-objects' option is used and no per-target flags are
1161 used. This should reduce the size of some projects a lot, because
1162 Automake used to output an explicit rule for each such object in
1165 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1166 object that must be built with explicit rules. It just outputs
1167 the rules required to build the kind of object considered: either
1168 the two .o and .obj rules for usual objects, or the .lo rule for
1171 * Change to Libtool support:
1173 - Libtool tags are used with libtool versions that support them.
1174 (I.e., with Libtool 1.5 or greater.)
1176 - Automake is now able to handle setups where a libtool library is
1177 conditionally installed in different directories, as in
1180 lib_LTLIBRARIES = liba.la
1182 pkglib_LTLIBRARIES = liba.la
1184 liba_la_SOURCES = ...
1186 * Changes to aclocal:
1188 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1189 really evaluated, before it decides to include them in aclocal.m4.
1190 This solves nasty problems with conditional redefinitions of
1191 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1192 *.m4 files to be included in any project using these macros.
1193 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1194 most famous instance of this bug.)
1196 - Do not complain about missing conditionally AC_REQUIREd macros
1197 that are not actually used. In 1.8.x aclocal would correctly
1198 determine which of these macros were really needed (and include
1199 only these in the package); unfortunately it would also require
1200 all of them to be present in order to run. This created
1201 situations were aclocal would not work on a tarball distributing
1202 all the macros it uses. For instance running aclocal on a project
1203 containing only the subset of the Gettext macros in use by the
1204 project did not work, because gettext conditionally requires other
1207 * Portability improvements:
1209 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1210 tar-pax. The new option filename-length-max=99 helps diagnosing
1211 filenames that are too long for tar-v7. (PR/414)
1213 - Variables aumented with `+=' are now automatically flattened (i.e.,
1214 trailing backslashes removed) and then wrapped around 80 colummns
1215 (adding trailing backslashes). In previous versions, a long series
1221 would result in a single-line definition of VAR that could possibly
1222 exceed the maximum line length of some make implementations.
1224 Non-augmented variables are still output as they are defined in
1229 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1230 Works the same as the old Fortran 77 implementation; just replace
1231 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1232 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1234 - Support for conditional _LISP.
1236 - Support for conditional -hook and -local rules (PR/428).
1238 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1240 - Automake will not write any Makefile.ins after the first error it
1241 encounters. The previous Makefile.ins (if any) will be left in
1242 place. (Warnings will not prevent output, but remember they can
1243 be turned into errors with -Werror.)
1245 - The restriction that SUBDIRS must contain direct children is gone.
1248 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1249 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1251 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1253 Bugs fixed in 1.8.5:
1255 * Long-standing bugs:
1257 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1258 so that `make distclean' and `make maintainer-clean' can work.
1260 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1262 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1264 - Polish diagnostic when no input file is found.
1266 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1268 Bugs fixed in 1.8.4:
1270 * Long-standing bugs:
1272 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1273 overridden by the user.
1275 - Honor PATH_SEPARATOR in various places of the Automake package, for
1278 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1281 - Fix install-sh so it can install the `mv' binary... using `mv'.
1283 - Fix tru64 dependency tracking for libtool objects.
1285 - Work around Exuberant Ctags when creating a TAGS files in a directory
1286 without files to scan but with subdirectories to include.
1288 * Bugs introduced by 1.8:
1290 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1291 not defined in the same conditions as the _LDADD that uses it.
1293 - Do not warn when JAVAROOT is overridden, this is legitimate.
1295 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1297 Bugs fixed in 1.8.3:
1299 * Long-standing bugs:
1301 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1302 or any of the other *dir variables contain a space.
1304 Please note that Automake does not and cannot support spaces in
1305 filenames that are involved during the build. This change affects
1306 only installation paths, so that `make install' does not bomb out
1307 in packages configured with
1308 ./configure --prefix '/c/Program Files'
1310 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1311 POSIXLY_CORRECT is set.
1313 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1314 since Autoconf 2.54, which defines LIBOBJS itself.
1316 - Fix a potential (but unlikely) race condition in parallel elisp
1317 builds. (Introduced in 1.7.3.)
1319 - Do not assume that users override _DEPENDENCIES in all conditions
1320 where Automake will try to define them.
1322 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1323 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1326 This fix also affects the $(mkdir_p) variable defined since
1327 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1328 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1330 - Secure temporary directory creation in `make distcheck'. (PR/413)
1332 - Do not generate two build rules for `parser.h' when the
1333 parser appears in two different conditionals.
1335 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1336 checking. Usually ./configure will not pick this shell; so this
1337 fix only helps cases where the shell is forced to /bin/sh.
1339 * Bugs introduced by 1.8:
1341 - In some situations (hand-written `m4_include's), aclocal would
1342 call the `File::Spec->rel2abs' method, which was only introduced
1343 in Perl 5.6. This new version reestablish support Perl 5.005.
1345 It is likely that the next major Automake releases will require at
1346 least Perl 5.6. Consider upgrading your development environment
1347 if you are still using the five-year-old Perl 5.005.
1349 - Automake would sometimes fail to define rules for targets listed
1350 in variables defined in multiple conditions. For instance on
1356 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1357 `b.$(OBJEXT): b.c' rule.
1359 * New sections in manual:
1361 - Third-Party Makefiles: how to interface third party Makefiles.
1362 - Upgrading: upgrading packages to newer Automake versions.
1363 - Multiple Outputs: handling tools that produce many outputs.
1365 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1369 * A (well known) portability bug slipped in the changes made to
1370 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1371 install anything on Tru64.
1373 * Fix install rules for conditionally built python files. (This never
1376 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1380 * Bugs introduced by 1.8:
1382 - Fix Config.pm import error with old Perl versions (at least
1383 5.005_03). One symptom is that aclocal could not find its macro
1386 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1387 created by `make install' are always world readable, even if the
1388 installer happens to have an overly restrictive umask (e.g. 077).
1389 This was a mistake and has been reverted. There are at least two
1390 reasons why we must not use `-m 0755':
1391 - it causes special bits like SGID to be ignored,
1392 - it may be too restrictive (some setups expect 775 directories).
1394 - Fix aclocal to honor definitions located in files which have been
1395 m4_included manually. aclocal 1.8 had been updated to check
1396 m4_included files for new requirements, but forgot that these
1397 m4_included files can also provide new definitions.
1399 Note that if you have such a setup, we recommend you get rid of
1400 it. In the past, there was a reason to m4_include files manually:
1401 aclocal used to duplicate entire M4 files into aclocal.m4, even
1402 files that were distributed. Some packages were therefore
1403 m4_including the distributed file directly, and playing some
1404 tricks to ensure aclocal would not copy that file to aclocal.m4,
1405 in order to limit the amount of duplication. Since aclocal 1.8.x
1406 will precisely output m4_includes for local M4 files, we recommend
1407 that you clean up your setup, removing all manual m4_includes and
1408 letting aclocal output them.
1410 - Output detailed menus in the Info version if the Automake manual,
1411 so that Emacs can locate the indexes.
1413 - configure.ac and configure were listed twice in DIST_COMMON (an
1414 internal variable where Automake lists configury files to
1415 distribute). This was harmless, but unaesthetic.
1417 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1418 This was an issue only in the Automake package itself, not in
1421 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1422 DEST:SRC. This was wrong, as some packages do
1423 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1426 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1427 argument. This caused two kinds of failures:
1428 - Rules installing data in a conditionally defined directory
1429 failed when that directory was undefined. In this case no
1430 argument was supplied.
1431 - `make installdirs' failed, because several directories were
1432 passed to $(mkdir_p). This was an issue only on platform
1433 were $(mkdir_p) is implemented with `install-sh -d'.
1434 $(mkdir_p) as been changed to accept 0 or more arguments, as
1437 * Long-standing bugs:
1439 - Fix an unexpected diagnostic occurring when users attempt
1440 to override some internal variables that Automake appends to.
1442 - aclocal now scans configure.ac for macro definitions (PR/319).
1444 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1445 distributes files which are outside itself (this usually occurs
1446 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1447 from a parent package), then `make distcheck' fails due to an
1448 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1449 (tests/subpkg2.test failure)
1451 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1452 In a VPATH-build configuration, `make install' would install
1453 nobase_ files to wrong locations.
1455 - Fix a Perl `uninitialized value' diagnostic occurring when
1456 automake complains that a Texinfo file does not have a
1457 @setfilename statement.
1459 - Erase config.status.lineno during `make distclean'. This file
1460 can be created by config.status. Automake already knew about
1461 configure.lineno, but forgot config.status.lineno.
1463 - Distribute all files, even those which are built and installed
1464 conditionally. This change affects files listed in conditionally
1465 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1466 as well as those listed in conditionally defined dist_*_DATA,
1467 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1469 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1470 doesn't conform to POSIX.
1472 - Normalize help strings for configure variables and options added
1477 - Check for python2.4 in AM_PATH_PYTHON.
1479 * Spurious failures in test suite:
1481 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1482 tests/ltconv.test: fix failures with CVS Libtool.
1483 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1484 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1485 fix failures with old Texinfo versions.
1487 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1493 - The NEWS file is more verbose.
1497 - Autoconf 2.58 or greater is required.
1501 - Default source file names in the absence of a _SOURCES declaration
1502 are made by removing any target extension before appending `.c', so
1503 to make the libtool module `foo.la' from `foo.c', you only need to
1506 lib_LTLIBRARIES = foo.la
1507 foo_la_LDFLAGS = -module
1509 For backward compatibility, foo_la.c will be used instead of
1510 foo.c if this file exists or is the explicit target of a rule.
1511 However -Wobsolete will warn about this deprecated naming.
1513 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1514 of being hard-coded in each $(AR) invocation, so they can be
1515 substituted from configure.ac. This has been requested by people
1516 dealing with non-POSIX ar implementations.
1518 - New warning option: -Woverride. This will warn about any user
1519 target or variable definitions which override Automake
1522 - Texinfo rules back up and restore info files when makeinfo fails.
1524 - Texinfo rules now support the `html' target.
1525 Running this requires Texinfo 4.0 or greater.
1527 `html' is a new recursive target, so if your package mixes
1528 hand-crafted `Makefile.in's with Automake-generated
1529 `Makefile.in's, you should adjust the former to support (or
1530 ignore) this target so that `make html' recurses successfully. If
1531 you had a custom `html' rule in your `Makefile.am', it's better to
1532 rename it as `html-local', otherwise your rule will override
1533 Automake's new rule (you can check that by running `automake
1534 -Woverride') and that will stop the recursion to subdirectories.
1536 Last but not least, this `html' rule is declared PHONY, even when
1537 overridden. Fortunately, it appears that few packages use a
1538 non-PHONY `html' rule.
1540 - Any file which is m4_included from configure.ac will appear as a
1541 configure and Makefile.in dependency, and will be automatically
1544 - The rules for rebuilding Makefiles and Makefile.ins will now
1545 rebuild all Makefiles and all Makefile.ins at once when one of
1546 configure's dependencies has changed. This is considerably faster
1547 than previous implementations, where config.status and automake
1548 were run separately in each directory (this still happens when you
1549 change a Makefile.am locally, without touching configure.ac or
1550 friends). Doing this also solves a longstanding issue: these
1551 rebuild rules failed to work when adding new directories to the
1552 tree, forcing you to run automake manually.
1554 - For similar reasons, the rules to rebuild configure,
1555 config.status, and aclocal.m4 are now defined in all directories.
1556 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1557 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1558 should better define them in all directories. This is easily done
1559 using an AC_SUBST (make sure you prefix these dependencies with
1560 $(top_srcdir) since this variable will appear at different
1561 levels of the build tree).
1563 - aclocal will now use `m4_include' instead of copying local m4
1564 files into aclocal.m4. (Local m4 files are those you ship with
1565 your project, other files will be copied as usual.)
1567 Because m4_included files are automatically distributed, it means
1568 for most projects there is no point in EXTRA_DISTing the list of
1569 m4 files which are used. (You can probably get rid of
1570 m4/Makefile.am if you had one.)
1572 - aclocal will avoid touching aclocal.m4 when possible, so that
1573 Autom4te's cache isn't needlessly invalidated. This behavior can
1574 be switched off with the new `--force' option.
1576 - aclocal now uses Autoconf's --trace to detect macros which are
1577 actually used and will no longer include unused macros simply
1578 because they where mentioned. This was often the case for macros
1579 called conditionally.
1581 - New options no-dist and no-dist-gzip.
1583 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1584 py-compile, and ylwrap, now all understand --version and --help.
1586 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1587 links as part of the distclean target and including source files in
1590 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1591 argument. The latter can be used to override the default behavior
1592 (which is to abort).
1594 - Automake will exit with $? = 63 on version mismatch. (So does
1595 Autoconf 2.58) missing knows this, and in this case it will
1596 emulate the tools as if they were absent. Because older versions
1597 of Automake and Autoconf did not use this exit code, this change
1598 will only be useful in projects generated with future versions of
1601 - When using AC_CONFIG_FILES with multiple input files, Automake
1602 generates the first ".in" input file for which a ".am" exists.
1603 (Former versions would try to use only the first input file.)
1605 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1606 idiom to disable byte-compilation of lisp_LISP files, it is
1607 recommended that you switch to using lisp_DATA. Note that
1608 this is not strictly equivalent: lisp_DATA will install elisp
1609 files even if emacs is not installed, while *_LISP do not
1610 install anything unless emacs is found.
1612 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1613 available. This selection is achieved through the Makefile
1614 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1615 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1616 `$(install_sh) -m 0755 -d'.
1620 - Because `mkdir -p' is available on most platforms, and we can use
1621 `install-sh -d' when it is not, the use of the mkinstalldirs
1622 script is being phased out. `automake --add-missing' no longer
1623 installs it, and if you remove mkinstalldirs from your package,
1624 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1626 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1627 gettextize and autopoint will install it when needed. Automake
1628 will continue to define the $(mkinstalldirs) and to distribute
1629 mkinstalldirs when this script is in the source tree.
1631 - AM_PROG_CC_STDC is now empty. The content of this macro was
1632 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1633 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1634 renaming should be safe, even if you have to support several,
1635 versions of Automake, because AC_PROG_CC defines this variable
1636 since Autoconf 2.54.)
1638 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1639 variable to override the aclocal.m4 dependencies computed
1640 (inaccurately) by older versions of Automake. Because Automake
1641 now tracks configure's m4 dependencies accurately (see m4_include
1642 above), the use of ACLOCAL_M4_SOURCES should be considered
1643 obsolete and will be flagged as such when running `automake
1648 - Defining programs conditionally using Automake conditionals no
1649 longer leads to a combinatorial explosion. The following
1650 construct used to be troublesome when used with dozens of
1665 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1667 - Due to implementation constraints, previous versions of Automake
1668 proscribed multiple conditional definitions of some variables
1678 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1679 This restriction has been lifted, and these variables now
1680 support multiple conditional definitions as do other variables.
1682 - Cleanup the definitions of $(distdir) and $(top_distdir).
1683 $(top_distdir) now points to the root of the distribution
1684 directory created during `make dist', as it did in Automake 1.4,
1685 not to the root of the build tree as it did in intervening
1686 versions. Furthermore these two variables are now only defined in
1687 the top level Makefile, and passed to sub-directories when running
1690 - The --no-force option now correctly checks the Makefile.in's
1691 dependencies before deciding not to update it.
1693 - Do not assume that make files are called Makefile in cleaning rules.
1695 - Update .info files in the source tree, not in the build tree. This
1696 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1697 used to update these files in the build tree (previous versions did
1698 it in the source tree too), and it caused several problems, varying
1699 from mere annoyance to portability issues.
1701 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1702 when --add-missing and --force-missing are used. For backward
1703 compatibility --add-missing will continue to install COPYING (in
1704 `gnu' strictness) when none of these three files exist, but this
1705 use is deprecated: you should better choose a license yourself and
1706 install it once for all in your source tree (and in your code
1709 - Fix ylwrap so that it does not overwrite header files that haven't
1710 changed, as the inline rule already does.
1712 - User-defined rules override automake-defined rules for the same
1713 targets, even when rules do not have commands. This is not new
1714 (and was documented), however some of the automake-generated
1715 rules have escaped this principle in former Automake versions.
1716 Rules for the following targets are affected by this fix:
1718 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1719 info, info-am, install-data-am, install-exec-am, install-info,
1720 install-info-am, install-man, installcheck-am, maintainer-clean,
1721 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1722 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1724 Practically it means that an attempt to supplement the dependencies
1725 of some target, as in
1727 clean: my-clean-rule
1729 will now *silently override* the automake definition of the
1730 rule for this target. Running `automake -Woverride' will diagnose
1731 all such overriding definitions.
1733 It should be noted that almost all of these targets support a *-local
1734 variant that is meant to supplement the automake-defined rule
1735 (See node `Extending' in the manual). The above rule should
1738 clean-local: my-clean-rule
1740 These *-local targets have been documented since at least
1741 Automake 1.2, so you should not fear the change if you have
1742 to support multiple automake versions.
1746 - The Automake manual is now distributed under the terms of the GNU FDL.
1748 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1750 - core dumps are no longer removed by the cleaning rules. There are
1751 at least three reasons for this:
1752 1. These files should not be created by any build step,
1753 so their removal do not fit any of the cleaning rules.
1754 Actually, they may be precious to the developer.
1755 2. If such file is created during a build, then it's clearly a
1756 bug Automake should not hide. Not removing the file will
1757 cause `make distcheck' to complain about its presence.
1758 3. Operating systems have different naming conventions for
1759 core dump files. A core file on one system might be a
1760 completely legitimate data file on another system.
1762 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1763 defined by Automake. This means that any definition in the
1764 environment will be used, unless overridden in the Makefile.am or
1765 on the command line. The old behavior, where these variables were
1766 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1767 AC_ARG_VARing each variable from configure.ac.
1769 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1770 documented. (The is not a new feature, these variables have
1771 been there since at least Automake 1.4.)

1775 Bugs fixed in 1.7.9:
1776 * Fix install-strip to work with nobase_ binaries.
1777 * Fix renaming of #line directives in ylwrap.
1778 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1780 Bugs fixed in 1.7.8:

1782 * Fix detection of Debian's install-info, broken since version 1.5.
1783 (Debian bug #213524).
1784 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1785 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1787 Bugs fixed in 1.7.7:
1788 * The implementation of automake's --no-force option is unreliable,
1789 so this option is ignored in this version. A real fix will appear in
1790 Automake 1.8. (Debian Bug #206299)
1791 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1792 argument is given. (PR/399)
1793 * Do not warn about leading `_' in variable names, even with -Wportability.
1794 * Support user redefinitions of TEXINFO_TEX.
1795 * depcomp: support AIX Compiler version 6.
1796 * Fix missing rebuilds during `make dist' with BSD make.

1816 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1817 that caused invalid Makefile.ins to be generated.

1835 * Minor documentation fixes.
1837 Bugs fixed in 1.7.3:
1838 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1839 * Query distutils for `pythondir' and `pythonexecdir', instead of
1840 using an hardcoded path. This should allow builds on 64-bit
1841 distributions that usually use lib64/ instead of lib/.
1842 * AM_PATH_PYTHON will also search for python2.3.
1843 * elisp files are now built all at once instead of one by one. Besides
1844 incurring a speed-up, this is required to support interdependent elisp files.
1845 * Support for DJGPP:
1846 - `make distcheck' will now work in `_inst/' and `_build' instead
1847 of `=inst/' and `=build/'
1848 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1849 - install/uninstall `*.i[0-9][0-9]'-style info files

1852 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1853 PACKAGE and VERSION.

1875 and augmented in another condition.
1876 * Fix ansi2knr rules for LIBOBJS sources.

1879 (PR/375, Debian Bug #168671)
1880 * Honor only the first @setfilename seen in a Texinfo file.
1881 * Treat "required file X not found" diagnostics as errors (exit status 1).

1903 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1904 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1906 * Install Python files even if they were built. (PR/369)
1907 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1908 version might not be defined in the latter. (PR/358)
1909 * Reorder arguments passed to a couple of commands, so things works
1910 when POSIXLY_CORRECT=1.
1911 * Fix a regex that can cause Perl to segfault on large input.

1923 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1926 * Autoconf 2.54 is required.
1927 * `aclocal' and `automake' will no longer warn about obsolete
1928 configure macros. This is done by `autoconf -Wobsolete'.
1929 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1930 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1931 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1932 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1933 `configure.ac' for you.
1934 * Support for per-program and per-library `_CPPFLAGS'.
1935 * New `ctags' target (builds CTAGS files).
1936 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1937 (see `automake --help' or the manual for a list of them).
1938 * Honor the WARNINGS environment variable.
1939 * Omit the call to depcomp when using gcc3: call the compiler directly.

1943 * Info files are now created in the build directory, not the source directory.
1944 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1946 * `make distcheck' will enforce DESTDIR support by attempting
1948 * `+=' can be used in conditionals, even if the augmented variable
1949 was defined for another condition.
1950 * Makefile fragments (inserted with `include') are always distributed.
1951 * Use Autoconf's --trace interface to inspect configure.ac and get
1952 a more accurate view of it.
1953 * Add support for extending aclocal's default macro search path
1954 using a `dirlist' file within the aclocal directory.
1955 * automake --output-dir is deprecated.
1956 * The part of the distcheck target that checks whether uninstall actually
1957 removes all installed files has been moved in a separate target,
1958 distuninstallcheck, so it can be overridden easily.
1962 * Support for AM_INIT_GETTEXT([external])
1963 * Bug fixes, including:
1964 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1965 - nobase_ programs and scripts honor --program-transform correctly.
1966 - Erase configure.lineno during `make distclean'.

1982 - Don't choke on AM_LDFLAGS definitions.
1983 - Clean libtool objects from subdirectories.
1984 - Allow configure variables with reserved suffix and unknown prefix
1985 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1986 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1989 * Autoconf 2.52 is required.
1990 * automake no longer run libtoolize.
1991 This is the job of autoreconf (from GNU Autoconf).
1992 * `dist' generates all the archive flavors, as did `dist-all'.
1993 * `dist-gzip' generates the Gzip tar file only.
1994 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1995 explosion. Makefile.in's keep a reasonable size.
1996 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1997 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1999 * `#line' of Lex and Yacc files are properly set.
2000 * EXTRA_DIST can contain generated directories.
2001 * Support for dot-less extensions in suffix rules.
2002 * The part of the distcheck target that checks whether distclean actually
2003 cleans all built files has been moved in a separate target, distcleancheck,
2004 so it can be overridden easily.

2013 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
2014 (Note that "pkgname" is not "tarname", see the manual for details.)
2015 It is also possible to pass a list of global Automake options as
2016 first argument to this new form of AM_INIT_AUTOMAKE.
2017 * Compiler-based assembler is now called `CCAS'; people expected `AS'
2018 to be a real assembler.
2019 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
2020 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
2021 * aclocal and automake are also installed with the version number
