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 - Support for the "Cygnus-style" trees (as enabled by the 'cygnus'
10 option) will be removed in the next major Automake release (1.13).
12 - The long-obsolete (since automake 1.10) AM_PROG_MKDIR m4 macro will
13 be removed in Automake 1.13. The $(mkdir_p) make variable and the
14 @mkdir_p@ substitution will still remain available (as aliases of
15 $(MKDIR_P)) for the moment, for better backward compatibility.
17 - Autoconf 2.65 or later will be required by the next major Automake
18 version (1.13). Until now, Automake has required Autoconf version
21 - Starting from the next major Automake version (1.13), the rules
22 to build pdf, ps and dvi output from Texinfo input will use the
23 '--build-dir' option by default. Since such an option was only
24 introduced in Texinfo 4.9, this means that Makefiles generated by
25 future Automake versions will require at least that version of
28 - Starting from the next major Automake version (1.13), the parallel
29 testsuite harness (previously only enabled by the 'parallel-tests'
30 option) will become the default one; the older serial testsuite
31 harness will still be available through the use of the 'serial-tests'
34 - The following long-obsolete m4 macros will be removed in the
35 next major Automake version (1.13):
37 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
38 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
39 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
40 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
41 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
42 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
43 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
44 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
45 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
46 of the now-removed automatic de-ANSI-fication
49 - All the "old alias" macros in 'm4/obsolete.m4' will be removed in
50 the next major Automake version (1.13).
52 - The '--acdir' option of aclocal is deprecated, and will probably
53 be removed in the next major Automake release (1.13). You should
54 use the options '--automake-acdir' and '--system-acdir' instead
55 (which have been introduced in Automake 1.11.2).
57 - The 'missing' script will no longer try to update the timestamp
58 of out-of-date files that require a maintainer-specific tool to be
59 remade, in case the user lacks such a tool (or has a too-old version
60 of it). In fact, starting from Automake 1.13, all it'll do will be
61 giving more useful warnings than a bare "command not found" from a
66 * Bugs introduced in 1.12.5:
68 - The maintainer rebuild rules for Makefiles and aclocal.m4 in Automake's
69 own build system works correctly again.
71 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
77 - The AM_PROG_VALAC macro has been enhanced to takes two further
78 optional arguments; it's signature now being
80 AM_PROG_VALAC([MINIMUM-VERSION], [ACTION-IF-FOUND],
81 [ACTION-IF-NOT-FOUND])
83 - By default, AM_PROG_VALAC no longer aborts the configure invocation
84 if the Vala compiler found is too old, but simply prints a warning
85 messages (as it did when the Vala compiler was not found). This
86 should avoid unnecessary difficulties for end users that just want
87 to compile the unmodified, distributed Vala-generated C sources,
88 but happens to have an old Vala compiler in their PATH. This fixes
91 - If no proper Vala compiler is found at configure runtime, AM_PROG_VALAC
92 will set the AC_SUBST'd variable 'VALAC' to 'valac' rather than to ':'.
93 This is a better default, because with it a triggered makefile rule
94 invoking a Vala compilation will clearly fail with an informative error
95 message like "valac: command not found", rather than silently, with
96 the error possibly going unnoticed or triggering harder-to-diagnose
97 fallout failures in later steps.
99 * Miscellaneous changes:
101 - automake and aclocal no longer honours the 'perllibdir' environment
102 variable. That had always been intended only as an hack required in
103 the testsuite, not meant for any use beyond that.
105 Bugs fixed in 1.12.5:
107 * Long-standing bugs:
109 - Automake no longer generates spurious remake rules invoking autoheader
110 to regenerate the template corresponding to header files specified after
111 the first one in AC_CONFIG_HEADERS (automake bug#12495).
113 - When wrapping Microsoft tools, the 'compile' script falls back to
114 finding classic 'libname.a' style libraries when 'name.lib' and
115 'name.dll.lib' aren't available.
117 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
121 * Warnings and deprecations:
123 - Warnings in the 'obsolete' category are enabled by default both in
124 automake and aclocal.
126 * Miscellaneous changes:
128 - Some testsuite weaknesses and spurious failures have been fixed.
130 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
134 * Miscellaneous changes:
136 - The '.m4' files provided by Automake no longer define serial numbers.
137 This should cause no difference in the behaviour of aclocal though.
139 - Some testsuite weaknesses and spurious failures have been fixed.
141 - There is initial support for automatic dependency tracking with the
142 Portland Group C/C++ compilers, thanks to the new new depmode 'pgcc'.
144 Bugs fixed in 1.12.3:
146 * Long-standing bugs:
148 - Instead of renaming only self-references of files (typically for
149 #lines), ylwrap now also renames references to the other generated
150 files. This fixes support for GLR and C++ parsers from Bison (PR
151 automake/491 and automake bug#7648): 'parser.c' now properly
152 #includes 'parser.h' instead of 'y.tab.h'.
154 - Generated files unknown to ylwrap are now preserved. This fixes
155 C++ support for Bison (automake bug#7648): location.hh and the
156 like are no longer discarded.
158 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
162 * Warnings and deprecations:
164 - Automake now issues a warning (in the 'portability' category) if
165 'configure.in' is used instead of 'configure.ac' as the Autoconf
166 input file. Such a warning will also be present in the next
167 Autoconf version (2.70).
171 - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
172 order (as done by the other recursive rules), rather than in the
173 inverse order. They used to do that in order to work a round a
174 limitation in an older implementation of the automatic dependency
175 tracking support, but that limitation had been lifted years ago
176 already, when the automatic dependency tracking based on side-effects
177 of compilation had been introduced.
179 - Cleaning rules for compiled objects (both "plain" and libtool) work
180 better when subdir objects are involved, not triggering a distinct
181 'rm' invocation for each such object. They do so by removing *any*
182 compiled object file that is in the same directory of a subdir
183 object. See automake bug#10697.
185 * Silent rules support:
187 - A new predefined $(AM_V_P) make variable is provided; it expands
188 to a shell conditional that can be used in recipes to know whether
189 make is being run in silent or verbose mode.
191 Bugs fixed in 1.12.2:
193 * SECURITY VULNERABILITIES!
195 - The 'distcheck' recipe no longer grants temporary world-write
196 permissions on the extracted distdir. Even if such rights were
197 only granted for a vanishingly small time window, the implied
198 race condition proved to be enough to allow a local attacker
199 to run arbitrary code with the privileges of the user running
200 "make distcheck". This is CVE-2012-3386.
202 * Long-standing bugs:
204 - The "recheck" targets behaves better in the face of build failures
205 related to previously failed tests. For example, if a test is a
206 compiled program that must be rerun by "make recheck", and its
207 compilation fails, it will still be rerun by further "make recheck"
208 invocations. See automake bug#11791.
210 * Bugs introduced by 1.12.1:
212 - Automake provides once again the '$(mkdir_p)' make variable and the
213 '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
214 for better backward-compatibility.
216 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
220 * New supported languages:
222 - Support for Objective C++ has been added; it should work similarly to
223 the support for Objective C.
225 * Deprecated obsolescent features:
227 - Use of the long-deprecated two- and three-arguments invocation forms
228 of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
229 category. Starting from some future major Automake release (likely
230 post-1.13), such usages will no longer be allowed.
232 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
233 now deprecated (its use triggers a warning in the 'obsolete' category).
234 It will be removed in the next major Automake release (1.13).
236 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
237 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
238 m4 macro are deprecated, eliciting a warning in the 'obsolete'
241 * Miscellaneous changes:
243 - The Automake test cases now require a proper POSIX-conforming shell.
244 Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) will no longer
245 be accepted. In most cases, the user shouldn't have to specify such
246 POSIX shell explicitly, since it will be looked up at configure time.
247 Still, when this lookup fails, or when the user wants to override its
248 conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be used (pointing
249 to the shell that will be used to run the Automake test cases).
251 Bugs fixed in 1.12.1:
253 * Bugs introduced by 1.12:
255 - Several weaknesses in Automake's own build system and test suite
258 * Bugs introduced by 1.11.3:
260 - When given non-option arguments, aclocal rejects them, instead of
261 silently ignoring them.
263 * Long-standing bugs:
265 - When the 'color-tests' option is in use, forcing of colored testsuite
266 output through "AM_COLOR_TESTS=always" works even if the terminal is
267 a non-ANSI one, i.e., if the TERM environment variable has a value of
270 - Several inefficiencies and poor performances in the implementation
271 of the parallel-tests 'check' and 'recheck' targets have been fixed.
273 - The post-processing of output "#line" directives done the ylwrap
274 script is more faithful w.r.t. files in a subdirectory; for example,
275 if the processed file is "src/grammar.y", ylwrap will correctly
276 produce directives like:
277 #line 7 "src/grammar.y"
282 * Bugs with new Perl versions:
284 - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
286 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
290 * Obsolete features removed:
292 - The never documented nor truly used script 'acinstall' has been
295 - Support for automatic de-ANSI-fication has been removed.
297 - The support for the "obscure" multilib feature has been removed
298 from Automake core (but remains available in the 'contrib/'
299 directory of the Automake distribution).
301 - Support for ".log -> .html" conversion and the check-html and
302 recheck-html targets has been removed from Automake core (but
303 remains available in the 'contrib/' directory of the Automake
306 - The deprecated 'lzma' compression format for distribution archives
307 has been removed, in favor of 'xz' and 'lzip'.
309 - The obsolete AM_WITH_REGEX macro has been removed.
311 - The long-deprecated options '--output-dir', '--Werror' and
312 '--Wno-error' have been removed.
314 - The chapter on the history of Automake has been moved out of the
315 reference manual, into a new dedicated Texinfo file.
319 - New 'cscope' target to build a cscope database for the source tree.
321 * Changes to Automake-generated testsuite harnesses:
323 - The new automake option 'serial-tests' has been introduced. It can
324 be used to explicitly instruct automake to use the older serial
325 testsuite harness. This is still the default at the moment, but it
326 might change in future versions.
328 - The 'recheck' target (provided by the parallel testsuite harness) now
329 depends on the 'all' target. This allows for a better user-experience
330 in test-driven development. See automake bug#11252.
332 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
333 and unexpected or internal error, or a failure to set up the test case
334 scenario) have their outcome reported as an 'ERROR' now. Previous
335 versions of automake reported such an outcome as a 'FAIL' (the only
336 difference with normal failures being that hard errors were counted
337 as failures even when the test originating them was listed in
340 - The testsuite summary displayed by the parallel-test harness has a
341 completely new format, that always list the numbers of passed, failed,
342 xfailed, xpassed, skipped and errored tests, even when these numbers
343 are zero (but using smart coloring when the color-tests option is in
346 - The default testsuite driver offered by the 'parallel-tests' option is
347 now implemented (partly at least) with the help of automake-provided
348 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
349 on code in the generated Makefile.in.
350 This has two noteworthy implications. The first one is that projects
351 using the 'parallel-tests' option should now either run automake with
352 the '--add-missing' option, or manually copy the 'test-driver' script
353 into their tree. The second, and more important, implication is that
354 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
355 no longer be used to define a test runner, and the command specified
356 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
357 program or script. For example, this is still a valid usage (albeit
360 TESTS_ENVIRONMENT = \
361 if test -n '$(STRICT_TESTS)'; then \
362 maybe_errexit='-e'; \
366 LOG_COMPILER = $(SHELL) $$maybe_errexit
368 OTOH, this is no longer a valid usage:
370 TESTS_ENVIRONMENT = \
371 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
375 TESTS_ENVIRONMENT = \
376 run_with_perl_or_shell () \
378 if grep -q '^#!.*perl' $$1; then
384 LOG_COMPILER = run_with_perl_or_shell
386 - The package authors can now use customary testsuite drivers within
387 the framework provided by the 'parallel-tests' testsuite harness.
388 Consistently with the existing syntax, this can be done by defining
389 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
391 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
392 to redirect/define file descriptors used by the test scripts.
394 - The parallel-tests harness generates now, in addition the '.log' files
395 holding the output produced by the test scripts, a new set of '.trs'
396 files, holding "metadata" derived by the execution of the test scripts;
397 among such metadata are the outcomes of the test cases run by a script.
399 - Initial and still experimental support for the TAP test protocol is
402 * Changes to Yacc and Lex support:
404 - C source and header files derived from non-distributed Yacc and/or
405 Lex sources are now removed by a simple "make clean" (while they were
406 previously removed only by "make maintainer-clean").
408 - Slightly backward-incompatible change, relevant only for use of Yacc
409 with C++: the extensions of the header files produced by the Yacc
410 rules are now modelled after the extension of the corresponding
411 sources. For example, yacc files named "foo.y++" and "bar.yy" will
412 produce header files named "foo.h++" and "bar.hh" respectively, where
413 they would have previously produced header files named simply "foo.h"
414 and "bar.h". This change offers better compatibility with 'bison -o'.
416 * Miscellaneous changes:
418 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
419 rather than 1, if the vala compiler found is too old.
421 - The build system of Automake itself now avoids the use of make
422 recursion as much as possible.
424 - Automake now prefers to quote 'like this' or "like this", rather
425 than `like this', in diagnostic message and generated Makefiles,
426 to accommodate the new GNU Coding Standards recommendations.
428 - Automake has a new option '--print-libdir' that prints the path of the
429 directory containing the Automake-provided scripts and data files.
431 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
433 - The rules to create pdf, dvi and ps output from Texinfo files now
434 works better with modern 'texi2dvi' script, by explicitly passing
435 it the '--clean' option to ensure stray auxiliary files are not
436 left to clutter the build directory.
438 - Automake can now generate silenced rules for texinfo outputs.
440 - Some auxiliary files that are automatically distributed by Automake
441 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
442 C sources) might now be listed in the DIST_COMMON variable in many
443 Makefile.in files, rather than in the top-level one.
445 - Messages of types warning or error from 'automake' and 'aclocal'
446 are now prefixed with the respective type, and presence of -Werror
449 - Automake's early configure-time sanity check now tries to avoid
450 sleeping for a second, which slowed down cached configure runs
451 noticeably. In that case, it will check back at the end of the
452 configure script to ensure that at least one second has passed, to
453 avoid time stamp issues with makefile rules rerunning autotools
456 - The warnings in the category 'extra-portability' are now enabled by
457 '-Wall'. In previous versions, one has to use '-Wextra-portability'
462 - Various minor bugfixes for recent or long-standing bugs.
464 * Bugs introduced by 1.11:
466 - The AM_COND_IF macro also works if the shell expression for the
467 conditional is no longer valid for the condition.
469 - The automake-provided parallel testsuite harness no longer fails
470 with BSD make used in parallel mode when there are test scripts in
471 a subdirectory, like in:
473 TESTS = sub/foo.test sub/bar.test
475 * Long-standing bugs:
477 - Automake's own build system finally have a real "installcheck" target.
479 - Vala-related cleanup rules are now more complete, and work better in
482 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
483 now automatically distributed also if the directory of the auxiliary
484 files coincides with the top-level directory.
486 - Automake now detects the presence of the '-d' flag in the various
487 '*YFLAGS' variables even when their definitions involve indirections
488 through other variables, such as in:
490 AM_YFLAGS = $(foo_opts)
492 - Automake now complains if a '*YFLAGS' variable has any conditional
493 content, not only a conditional definition.
495 - Explicit enabling and/or disabling of Automake warning categories
496 through the '-W...' options now always takes precedence over the
497 implicit warning level implied by Automake strictness (foreign, gnu
498 or gnits), regardless of the order in which such strictness and
499 warning flags appear. For example, a setting like:
500 AUTOMAKE_OPTIONS = -Wall --foreign
501 will cause the warnings in category 'portability' to be enabled, even
502 if those warnings are by default disabled in 'foreign' strictness.
504 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
506 Bugs fixed in 1.11.5:
508 * Bugs introduced by 1.11.3:
510 - Vala files with '.vapi' extension are now recognized and handled
511 correctly again. See automake bug#11222.
513 - Vala support work again for projects that contain some program
514 built from '.vala' (and possibly '.c') sources and some other
515 program built from '.c' sources *only*. See automake bug#11229.
517 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
521 * Miscellaneous changes:
523 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
524 symbol index) modifiers as well as the "s" action, as the symbol index
525 is created unconditionally by Microsoft lib. Also, the "q" (quick)
526 action is now a synonym for "r" (replace). Also, the script has been
527 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
529 - When the 'compile' script is used to wrap MSVC, it now accepts an
530 optional space between the -I, -L and -l options and their respective
531 arguments, for better POSIX compliance.
533 - There is an initial, experimental support for automatic dependency
534 tracking with tcc (the Tiny C Compiler). Its associated depmode is
535 currently recognized as "icc" (but this and other details are likely
536 to change in future versions).
538 - Automatic dependency tracking now works also with the IBM XL C/C++
539 compilers, thanks to the new new depmode 'xlc'.
541 Bugs fixed in 1.11.4:
543 * Bugs introduced by 1.11.2:
545 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
546 no longer cause spurious failures upon "make install".
548 - The user can now instruct the 'uninstall-info' rule not to update
549 the '${infodir}/dir' file by exporting the environment variable
550 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
551 with how the 'install-info' rule operates since automake 1.11.2.
553 * Long-standing bugs:
555 - It is now possible for a foo_SOURCES variable to hold Vala sources
556 together with C header files, as well as with sources and headers for
557 other supported languages (e.g., C++). Previously, only mixing C and
558 Vala sources was supported.
560 - If "aclocal --install" is used, and the first directory specified with
561 '-I' is non-existent, aclocal will now create it before trying to copy
564 - An empty declaration of a "foo_PRIMARY" no longer cause the generated
565 install rules to create an empty $(foodir) directory; for example, if
566 Makefile.am contains something like:
570 pkglibexec_SCRIPTS += bar.sh
573 the $(pkglibexec) directory will not be created upon "make install".
575 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
579 * Miscellaneous changes:
581 - Automake's own build system is more silent by default, making use of
582 the 'silent-rules' option.
584 - The master copy of the 'gnupload' script is now maintained in gnulib,
587 - The 'missing' script no longer tries to wrap calls to 'tar'.
589 - "make dist" no longer wraps 'tar' invocations with the 'missing'
590 script. Similarly, the obsolescent variable '$(AMTAR)' (which you
591 shouldn't be using BTW ;-) no longer invokes the 'missing' script
592 to wrap tar, but simply invokes the 'tar' program itself.
594 - "make dist" can now create lzip-compressed tarballs.
596 - In the Automake info documentation, the Top node and the nodes about
597 the invocation of the automake and aclocal programs have been renamed;
598 now, calling "info automake" will open the Top node, while calling
599 "info automake-invocation" and "info aclocal-invocation" will access
600 the nodes about the invocation of respectively automake and aclocal.
602 - Automake is now distributed as a gzip-compressed and an xz-compressed
603 tarball. Previously, bzip2 was used instead of xz.
605 - The last relics of Python 1.5 support have been removed from the
606 AM_PATH_PYTHON macro.
608 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
609 and adds them to the normal list of dependencies, but without
610 overwriting the foo_DEPENDENCIES variable, which is normally computed
613 Bugs fixed in 1.11.3:
615 * Bugs introduced by 1.11.2:
617 - Automake now correctly recognizes the prefix/primary combination
618 'pkglibexec_SCRIPTS' as valid.
620 - The parallel-tests harness no longer trips on sed implementations
621 with stricter limits on the length of input lines (problem seen at
624 * Long-standing bugs:
626 - The "deleted header file problem" for *.am files is avoided by stub
627 rules. This allows 'make' to trigger a rerun of 'automake' also if
628 some previously needed '.am' file has been removed.
630 - The 'silent-rules' option now generates working makefiles even
631 for the uncommon 'make' implementations that do not support the
632 nested-variables extension to POSIX 2008. For such 'make'
633 implementations, whether a build is silent is determined at
634 configure time, and cannot be overridden at make time with
635 "make V=0" or "make V=1".
637 - Vala support now works better in VPATH setups.
639 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
643 * Changes to aclocal:
645 - The `--acdir' option is deprecated. Now you should use the new options
646 `--automake-acdir' and `--system-acdir' instead.
648 - The `ACLOCAL_PATH' environment variable is now interpreted as a
649 colon-separated list of additional directories to search after the
650 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
651 and before the system acdir (by default ${prefix}/share/aclocal).
653 * Miscellaneous changes:
655 - The Automake support for automatic de-ANSI-fication has been
656 deprecated. It will probably be removed in the next major Automake
659 - The `lzma' compression scheme and associated automake option `dist-lzma'
660 is obsoleted by `xz' and `dist-xz' due to upstream changes.
662 - You may adjust the compression options used in dist-xz and dist-bzip2.
663 The default is now merely -e for xz, but still -9 for bzip; you may
664 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
665 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
667 - The `compile' script now converts some options for MSVC for a better
668 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
670 - The py-compile script now accepts empty arguments passed to the options
671 `--destdir' and `--basedir', and complains about unrecognized options.
672 Moreover, a non-option argument or a special `--' argument terminates
675 - A developer that needs to pass specific flags to configure at "make
676 distcheck" time can now, and indeed is advised to, do so by defining
677 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
678 instead of the old DISTCHECK_CONFIGURE_FLAGS.
679 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
680 user; still, the old Makefile.am files that used to define it will
681 still continue to work as before.
683 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
684 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
685 This new macro is required for LIBRARIES and LTLIBRARIES when automake
686 is run with -Wextra-portability and -Werror.
688 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
689 file generated by automake-provided rules by defining the special make
690 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
692 - The `install-info' rule can now be instructed not to create/update
693 the `${infodir}/dir' file, by exporting the new environment variable
694 `AM_UPDATE_INFO_DIR' to the value "no".
696 Bugs fixed in 1.11.2:
698 * Bugs introduced by 1.11:
700 - The parallel-tests driver no longer produces erroneous results with
701 Tru64/OSF 5.1 sh upon unreadable log files.
703 - The `parallel-tests' test driver does not report spurious successes
704 when used with concurrent FreeBSD make (e.g., "make check -j3").
706 - When the parallel-tests driver is in use, automake now explicitly
707 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
708 instead of issuing confusing and apparently unrelated error messages
709 (e.g., "non-POSIX variable name", "bad characters in variable name",
710 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
711 silently producing broken `Makefile.in' files.
713 - The `silent-rules' option now truly silences all compile rules, even
714 when dependency tracking is disabled. Also, when `silent-rules' is
715 not used, `make' output no longer contains spurious backslash-only
716 lines, thus once again matching what Automake did before 1.11.
718 - The AM_COND_IF macro also works if the shell expression for the
719 conditional is no longer valid for the condition.
721 * Long-standing bugs:
723 - The order of Yacc and Lex flags is fixed to be consistent with other
724 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
725 $(LFLAGS), so that the user variables override the developer variables.
727 - "make distcheck" now correctly complains also when "make uninstall"
728 leaves one and only one file installed in $(prefix).
730 - A "make uninstall" issued before a "make install", or after a mere
731 "make install-data" or a mere "make install-exec" does not spuriously
734 - Automake now warns about more primary/directory invalid combinations,
735 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
737 - Rules generated by Automake now try harder to not change any files when
738 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
739 Yacc source files and the rule to update config.h.
741 - Several scripts and the parallel-tests testsuite driver now exit with
742 the right exit status upon receiving a signal.
744 - A per-Makefile.am setting of -Werror does not erroneously carry over
745 to the handling of other Makefile.am files.
747 - The code for automatic dependency tracking works around a Solaris
748 make bug triggered by sources containing repeated slashes when the
749 `subdir-objects' option was used.
751 - The makedepend and hp depmodes now work better with VPATH builds.
753 - Java sources specified with check_JAVA are no longer compiled for
754 "make all", but only for "make check".
756 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
757 and error out if `javadir' is undefined, instead of silently producing
758 a broken Makefile.in.
760 - aclocal and automake now honour the configure-time definitions of
761 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
763 - The `install-info' recipe no longer tries to guess whether the
764 `install-info' program is from Debian or from GNU, and adaptively
765 change its behaviour; this has proven to be frail and easy to
768 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
770 Bugs fixed in 1.11.1:
772 - Lots of minor bugfixes.
774 * Bugs introduced by 1.11:
776 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
777 trailing white space in the test list (`TESTS = foo $(EMPTY)').
779 * Long standing bugs:
781 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
782 even if the `--prefix' argument pointed outside of a system directory.
783 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
784 `get_python_lib' function if it points outside the configured prefix,
785 unless the `--prefix' argument was either `/usr' or below `/System'.
787 - The testsuite does not try to change the mode of `ltmain.sh' files from
788 a Libtool installation (symlinked to test directories) any more.
790 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
791 tools are preferred in a cross-compile setup.
793 - The distribution is tarred up with mode 755 now by the `dist*' targets.
794 This fixes a race condition where untrusted users could modify files
795 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
796 build directory was world-searchable. This is CVE-2009-4029.
798 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
802 * Version requirements:
804 - Autoconf 2.62 or greater is required.
806 * Changes to aclocal:
808 - The autoconf version check implemented by aclocal in aclocal.m4
809 (and new in Automake 1.10) is degraded to a warning. This helps
810 in the common case where the Autoconf versions used are compatible.
812 * Changes to automake:
814 - The automake program can run multiple threads for creating most
815 Makefile.in files concurrently, if at least Perl 5.7.2 is available
816 with interpreter-based threads enabled. Set the environment variable
817 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
818 enable this experimental feature.
820 * Changes to Libtool support:
822 - Libtool generic flags are now passed to the install and uninstall
825 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
826 config.lt is removed correctly now.
830 - subdir-object mode works now with Fortran (F77, FC, preprocessed
831 Fortran, and Ratfor).
833 - For files with extension .f90, .f95, .f03, or .f08, the flag
834 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
836 - Files with extension .sx are also treated as preprocessed assembler.
838 - The default source file extension (.c) can be overridden with
839 AM_DEFAULT_SOURCE_EXT now.
841 - Python 3.0 is supported now, Python releases prior to 2.0 are no
844 - AM_PATH_PYTHON honors python's idea about the site directory.
846 - There is initial support for the Vala programming language, when using
849 * Miscellaneous changes:
851 - Automake development is done in a git repository on Savannah now, see
853 http://git.sv.gnu.org/gitweb/?p=automake.git
855 A read-only CVS mirror is provided at
857 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
858 checkout -d automake HEAD
860 - "make dist" can now create xz-compressed tarballs,
861 as well as (deprecated?) lzma-compressed tarballs.
863 - `automake --add-missing' will by default install the GPLv3 file as
864 COPYING if it is missing. It will also warn that the license file
865 should be added to source control. Note that Automake will never
866 overwrite an existing COPYING file, even when the `--force-missing'
869 - The manual is now distributed under the terms of the GNU FDL 1.3.
871 - Automake ships and installs man pages for automake and aclocal now.
873 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
875 - install-sh supports -C, which does not update the installed file
876 (and its time stamps) if the contents did not change.
878 - The `gnupload' script has been revamped.
880 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
882 - The targets `install' and `uninstall' are more efficient now, in that
883 for example multiple files from one Automake variable such as
884 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
885 invocation if they do not have to be renamed.
887 Both install and uninstall may sometimes enter (`cd' into) the target
888 installation directory now, when no build-local scripts are used.
890 Both install and uninstall do not fail anymore but do nothing if an
891 installation directory variable like `bindir' is set to the empty string.
893 For built-in rules, `make install' now fails reliably if installation
894 of a file failed. Conversely, `make uninstall' even succeeds when
895 issued multiple times.
897 These changes may need some adjustments from users: For example,
898 some `install' programs refuse to install multiple copies of the
899 same file in one invocation, so you may need to remove duplicate
900 entries from file lists.
902 Also, within one set of files, say, nobase_data_DATA, the order of
903 installation may be changed, or even unstable among different hosts,
904 due to the use of associative arrays in awk. The increased use of
905 awk matches a similar move in Autoconf to provide for better scaling.
907 Further, most undocumented per-rule install command variables such as
908 binSCRIPT_INSTALL have been removed because they are not needed any
909 more. Packages which use them should be using the appropriate one of
910 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
911 counterpart, depending on the type of files and the need for automatic
912 target directory creation.
914 - The "deleted header file problem" for *.m4 files is avoided by
915 stub rules. This allows `make' to trigger a rerun of `aclocal'
916 also if some previously needed macro file has been removed.
918 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
919 an otherwise up to date tree.
921 - The `color-tests' option causes colored test result output on terminals.
923 - The `parallel-tests' option enables a new test driver that allows for
924 parallel test execution, inter-test dependencies, lazy test execution
925 for unit-testing, re-testing only failed tests, and formatted result output
926 as RST (reStructuredText) and HTML. Enabling this option may require some
927 changes to your test suite setup; see the manual for details.
929 - The `silent-rules' option enables Linux kernel-style silent build output.
930 This option requires the widely supported but non-POSIX `make' feature
931 of recursive variable expansion, so do not use it if your package needs
932 to build with `make' implementations that do not support it.
934 To enable less verbose build output, the developer has to use the Automake
935 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
936 macro. The user may then set the default verbosity by passing the
937 `--enable-silent-rules' option to `configure'. At `make' run time, this
938 default may be overridden using `make V=0' for less verbose, and `make V=1'
939 for backward-compatible verbose output.
941 - New prefix `notrans_' for manpages which should not be transformed
942 by --program-transform.
944 - New macro AM_COND_IF for conditional evaluation and conditional
947 - For AC_CONFIG_LINKS, if source and destination are equal, do not
948 remove the file in a non-VPATH build. Such setups work with Autoconf
951 - AM_MAINTAINER_MODE now allows for an optional argument specifying
954 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
955 useful especially for multi-line values.
957 - Automake's early configure-time sanity check now diagnoses an
958 unsafe absolute source directory name and makes configure fail.
960 - The Automake macros and rules cope better with whitespace in the
961 current directory name, as long as the relative path to `configure'
962 does not contain whitespace. To this end, the values of `$(MISSING)'
963 and `$(install_sh)' may contain suitable quoting, and their expansion
964 might need `eval'uation if used outside of a makefile. These
965 undocumented variables may be used in several documented macros such
966 as $(AUTOCONF) or $(MAKEINFO).
970 * Long-standing bugs:
972 - Fix aix dependency tracking for libtool objects.
974 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
975 unnecessary use of the `compile' script.
977 - For nobase_*_LTLIBRARIES with nonempty directory components, the
978 correct `-rpath' argument is used now.
980 - `config.status --file=Makefile depfiles' now also works with the
981 extra quoting used internally by Autoconf 2.62 and newer
982 (it used to work only without the `--file=' bit).
984 - The `missing' script works better with versioned tool names.
986 - Semantics for `missing help2man' have been revamped:
988 Previously, if `help2man' was not present, `missing help2man' would have
989 the following semantics: if some man page was out of date but present, then
990 a warning would be printed, but the exit status was 0. If the man page was
991 not present at all, then `missing' would create a replacement man page
992 containing an error message, and exit with a status of 2. This does not play
993 well with `make': the next run will see this particular man page as being up
994 to date, and will only error out on the next generated man page, if any;
995 repeat until all pages are done. This was not desirable.
997 These are the new semantics: if some man page is not present, and help2man
998 is not either, then `missing' will warn and generate the replacement page
999 containing the error message, but exit successfully. However, `make dist'
1000 will ensure that no such bogus man pages are packaged into a tarball.
1002 - Targets provided by automake behave better with `make -n', in that they
1003 take care not to create files.
1005 - `config.status Makefile... depfiles' works fine again in the presence of
1006 disabled dependency tracking.
1008 - The default no-op recursive rules for these targets also work with BSD make
1009 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
1011 - `make distcheck' works also when both a directory and some file below it
1012 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
1014 - Texinfo dvi, ps, pdf, and html output files are not removed upon
1015 `make mostlyclean' any more; only the LaTeX by-products are.
1017 - Renamed objects also work with the `subdir-objects' option and
1018 source file languages which Automake does not know itself.
1020 - `automake' now correctly complains about variable assignments which are
1021 preceded by a comment, extend over multiple lines with backslash-escaped
1022 newlines, and end in a comment sign. Previous versions would silently
1023 and wrongly ignore such assignments completely.
1025 * Bugs introduced by 1.10:
1027 - Fix output of dummy dependency files in presence of post-processed
1028 Makefile.in's again, but also cope with long lines.
1030 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
1031 that have been declared as programs in the same Makefile.
1032 This is for consistency with the analogous change to TESTS in 1.10.
1034 - Fix order of standard includes to again be `-I. -I$(srcdir)',
1035 followed by directories containing config headers.
1037 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1041 * Version requirements:
1043 - Autoconf 2.60 or greater is required.
1045 - Perl 5.6 or greater is required.
1047 * Changes to aclocal:
1049 - aclocal now also supports -Wmumble and -Wno-mumble options.
1051 - `dirlist' entries (for the aclocal search path) may use shell
1052 wildcards such as `*', `?', or `[...]'.
1054 - aclocal supports an --install option that will cause system-wide
1055 third-party macros to be installed in the local directory
1056 specified with the first -I flag. This option also uses #serial
1057 lines in M4 files to upgrade local macros.
1059 The new aclocal options --dry-run and --diff help to review changes
1060 before they are installed.
1062 - aclocal now outputs an autoconf version check in aclocal.m4 in
1063 projects using automake.
1065 For a few years, automake and aclocal have been calling autoconf
1066 (or its underlying engine autom4te) to accurately retrieve the
1067 data they need from configure.ac and its siblings. Doing so can
1068 only work if all autotools use the same version of autoconf. For
1069 instance a Makefile.in generated by automake for one version of
1070 autoconf may stop working if configure is regenerated with another
1071 version of autoconf, and vice versa.
1073 This new version check ensures that the whole build system has
1074 been generated using the same autoconf version.
1076 * Support for new Autoconf macros:
1078 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
1080 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
1081 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
1082 in different directories. However, only one instance of such a
1083 library objects directory is supported.
1085 * Change to Libtool support:
1087 - Libtool generic flags (those that go before the --mode=MODE option)
1088 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
1090 * Yacc and Lex changes:
1092 - The rebuild rules for distributed Yacc and Lex output will avoid
1093 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
1096 - ylwrap is now always used for lex and yacc source files,
1097 regardless of whether there is more than one source per directory.
1099 * Languages changes:
1101 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
1102 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
1103 tracking, unlike non-preprocessed assembler (*.s).
1105 - subdir-object mode works now with Assembler. Automake assumes
1106 that the compiler understands `-c -o'.
1108 - Preprocessed assembler (*.S) compilation now also honors
1109 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
1111 - Improved support for Objective C:
1112 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
1113 - A new section of the manual documents the support.
1115 - New support for Unified Parallel C:
1116 - AM_PROG_UPC looks for a UPC compiler.
1117 - A new section of the manual documents the support.
1119 - Per-target flags are now correctly handled in link rules.
1121 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
1122 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
1123 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
1124 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
1126 The fix for compiler flags (i.e., using maude_CFLAGS instead of
1127 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
1128 is expected to work (and actually works during compilation).
1130 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
1131 "in addition to" breaks backward compatibility with older versions.
1132 If your package used both variables, as in
1134 AM_LDFLAGS = common flags
1135 bin_PROGRAMS = a b c
1136 a_LDFLAGS = more flags
1139 and assumed *_LDFLAGS would sum up, you should rewrite it as
1141 AM_LDFLAGS = common flags
1142 bin_PROGRAMS = a b c
1143 a_LDFLAGS = $(AM_LDFLAGS) more flags
1146 This new behavior of *_LDFLAGS is more coherent with other
1147 per-target variables, and the way *_LDFLAGS variables were
1148 considered internally.
1150 * New installation targets:
1152 - New targets mandated by GNU Coding Standards:
1157 By default they will only install Texinfo manuals.
1158 You can customize them with *-local variants:
1164 - The undocumented recursive target `uninstall-info' no longer exists.
1165 (`uninstall' is in charge of removing all possible documentation
1166 flavors, including optional formats such as dvi, ps, or info even
1167 when `no-installinfo' is used.)
1169 * Miscellaneous changes:
1171 - Automake no longer complains if input files for AC_CONFIG_FILES
1172 are specified using shell variables.
1174 - clean, distribution, or rebuild rules are normally disabled for
1175 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
1176 AC_CONFIG_LINK specified using shell variables. However, if these
1177 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
1178 be able to output rules anyway.
1179 (See the Automake documentation for AC_CONFIG_FILES.)
1181 - $(EXEEXT) is automatically appended to filenames of TESTS
1182 that have been declared as programs in the same Makefile.
1183 This is mostly useful when some check_PROGRAMS are listed in TESTS.
1185 - `-Wportability' has finally been turned on by default for `gnu' and
1186 `gnits' strictness. This means, automake will complain about %-rules
1187 or $(GNU Make functions) unless you switch to `foreign' strictness or
1188 use `-Wno-portability'.
1190 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
1191 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
1192 $(mkdir_p) variable is still defined (to the same value as
1193 $(MKDIR_P)) but should be considered obsolete. If you are using
1194 $(mkdir_p) in some of your rules, please plan to update them to
1195 $(MKDIR_P) at some point.
1197 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
1198 They still work in this release, but may be withdrawn in a future one.
1200 - Inline compilation rules for gcc3-style dependency tracking are
1203 - Automake installs a "Hello World!" example package in $(docdir).
1204 This example is used throughout the new "Autotools Introduction"
1205 chapter of the manual.
1207 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1211 * Makefile.in bloat reduction:
1213 - Inference rules are used to compile sources in subdirectories when
1214 the `subdir-objects' option is used and no per-target flags are
1215 used. This should reduce the size of some projects a lot, because
1216 Automake used to output an explicit rule for each such object in
1219 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1220 object that must be built with explicit rules. It just outputs
1221 the rules required to build the kind of object considered: either
1222 the two .o and .obj rules for usual objects, or the .lo rule for
1225 * Change to Libtool support:
1227 - Libtool tags are used with libtool versions that support them.
1228 (I.e., with Libtool 1.5 or greater.)
1230 - Automake is now able to handle setups where a libtool library is
1231 conditionally installed in different directories, as in
1234 lib_LTLIBRARIES = liba.la
1236 pkglib_LTLIBRARIES = liba.la
1238 liba_la_SOURCES = ...
1240 * Changes to aclocal:
1242 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1243 really evaluated, before it decides to include them in aclocal.m4.
1244 This solves nasty problems with conditional redefinitions of
1245 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1246 *.m4 files to be included in any project using these macros.
1247 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1248 most famous instance of this bug.)
1250 - Do not complain about missing conditionally AC_REQUIREd macros
1251 that are not actually used. In 1.8.x aclocal would correctly
1252 determine which of these macros were really needed (and include
1253 only these in the package); unfortunately it would also require
1254 all of them to be present in order to run. This created
1255 situations were aclocal would not work on a tarball distributing
1256 all the macros it uses. For instance running aclocal on a project
1257 containing only the subset of the Gettext macros in use by the
1258 project did not work, because gettext conditionally requires other
1261 * Portability improvements:
1263 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1264 tar-pax. The new option filename-length-max=99 helps diagnosing
1265 filenames that are too long for tar-v7. (PR/414)
1267 - Variables aumented with `+=' are now automatically flattened (i.e.,
1268 trailing backslashes removed) and then wrapped around 80 colummns
1269 (adding trailing backslashes). In previous versions, a long series
1275 would result in a single-line definition of VAR that could possibly
1276 exceed the maximum line length of some make implementations.
1278 Non-augmented variables are still output as they are defined in
1283 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1284 Works the same as the old Fortran 77 implementation; just replace
1285 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1286 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1288 - Support for conditional _LISP.
1290 - Support for conditional -hook and -local rules (PR/428).
1292 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1294 - Automake will not write any Makefile.ins after the first error it
1295 encounters. The previous Makefile.ins (if any) will be left in
1296 place. (Warnings will not prevent output, but remember they can
1297 be turned into errors with -Werror.)
1299 - The restriction that SUBDIRS must contain direct children is gone.
1302 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1303 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1305 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1307 Bugs fixed in 1.8.5:
1309 * Long-standing bugs:
1311 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1312 so that `make distclean' and `make maintainer-clean' can work.
1314 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1316 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1318 - Polish diagnostic when no input file is found.
1320 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1322 Bugs fixed in 1.8.4:
1324 * Long-standing bugs:
1326 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1327 overridden by the user.
1329 - Honor PATH_SEPARATOR in various places of the Automake package, for
1332 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1335 - Fix install-sh so it can install the `mv' binary... using `mv'.
1337 - Fix tru64 dependency tracking for libtool objects.
1339 - Work around Exuberant Ctags when creating a TAGS files in a directory
1340 without files to scan but with subdirectories to include.
1342 * Bugs introduced by 1.8:
1344 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1345 not defined in the same conditions as the _LDADD that uses it.
1347 - Do not warn when JAVAROOT is overridden, this is legitimate.
1349 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1351 Bugs fixed in 1.8.3:
1353 * Long-standing bugs:
1355 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1356 or any of the other *dir variables contain a space.
1358 Please note that Automake does not and cannot support spaces in
1359 filenames that are involved during the build. This change affects
1360 only installation paths, so that `make install' does not bomb out
1361 in packages configured with
1362 ./configure --prefix '/c/Program Files'
1364 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1365 POSIXLY_CORRECT is set.
1367 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1368 since Autoconf 2.54, which defines LIBOBJS itself.
1370 - Fix a potential (but unlikely) race condition in parallel elisp
1371 builds. (Introduced in 1.7.3.)
1373 - Do not assume that users override _DEPENDENCIES in all conditions
1374 where Automake will try to define them.
1376 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1377 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1380 This fix also affects the $(mkdir_p) variable defined since
1381 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1382 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1384 - Secure temporary directory creation in `make distcheck'. (PR/413)
1386 - Do not generate two build rules for `parser.h' when the
1387 parser appears in two different conditionals.
1389 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1390 checking. Usually ./configure will not pick this shell; so this
1391 fix only helps cases where the shell is forced to /bin/sh.
1393 * Bugs introduced by 1.8:
1395 - In some situations (hand-written `m4_include's), aclocal would
1396 call the `File::Spec->rel2abs' method, which was only introduced
1397 in Perl 5.6. This new version reestablish support Perl 5.005.
1399 It is likely that the next major Automake releases will require at
1400 least Perl 5.6. Consider upgrading your development environment
1401 if you are still using the five-year-old Perl 5.005.
1403 - Automake would sometimes fail to define rules for targets listed
1404 in variables defined in multiple conditions. For instance on
1410 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1411 `b.$(OBJEXT): b.c' rule.
1413 * New sections in manual:
1415 - Third-Party Makefiles: how to interface third party Makefiles.
1416 - Upgrading: upgrading packages to newer Automake versions.
1417 - Multiple Outputs: handling tools that produce many outputs.
1419 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1423 * A (well known) portability bug slipped in the changes made to
1424 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1425 install anything on Tru64.
1427 * Fix install rules for conditionally built python files. (This never
1430 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1434 * Bugs introduced by 1.8:
1436 - Fix Config.pm import error with old Perl versions (at least
1437 5.005_03). One symptom is that aclocal could not find its macro
1440 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1441 created by `make install' are always world readable, even if the
1442 installer happens to have an overly restrictive umask (e.g. 077).
1443 This was a mistake and has been reverted. There are at least two
1444 reasons why we must not use `-m 0755':
1445 - it causes special bits like SGID to be ignored,
1446 - it may be too restrictive (some setups expect 775 directories).
1448 - Fix aclocal to honor definitions located in files which have been
1449 m4_included manually. aclocal 1.8 had been updated to check
1450 m4_included files for new requirements, but forgot that these
1451 m4_included files can also provide new definitions.
1453 Note that if you have such a setup, we recommend you get rid of
1454 it. In the past, there was a reason to m4_include files manually:
1455 aclocal used to duplicate entire M4 files into aclocal.m4, even
1456 files that were distributed. Some packages were therefore
1457 m4_including the distributed file directly, and playing some
1458 tricks to ensure aclocal would not copy that file to aclocal.m4,
1459 in order to limit the amount of duplication. Since aclocal 1.8.x
1460 will precisely output m4_includes for local M4 files, we recommend
1461 that you clean up your setup, removing all manual m4_includes and
1462 letting aclocal output them.
1464 - Output detailed menus in the Info version if the Automake manual,
1465 so that Emacs can locate the indexes.
1467 - configure.ac and configure were listed twice in DIST_COMMON (an
1468 internal variable where Automake lists configury files to
1469 distribute). This was harmless, but unaesthetic.
1471 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1472 This was an issue only in the Automake package itself, not in
1475 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1476 DEST:SRC. This was wrong, as some packages do
1477 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1480 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1481 argument. This caused two kinds of failures:
1482 - Rules installing data in a conditionally defined directory
1483 failed when that directory was undefined. In this case no
1484 argument was supplied.
1485 - `make installdirs' failed, because several directories were
1486 passed to $(mkdir_p). This was an issue only on platform
1487 were $(mkdir_p) is implemented with `install-sh -d'.
1488 $(mkdir_p) as been changed to accept 0 or more arguments, as
1491 * Long-standing bugs:
1493 - Fix an unexpected diagnostic occurring when users attempt
1494 to override some internal variables that Automake appends to.
1496 - aclocal now scans configure.ac for macro definitions (PR/319).
1498 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1499 distributes files which are outside itself (this usually occurs
1500 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1501 from a parent package), then `make distcheck' fails due to an
1502 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1503 (tests/subpkg2.test failure)
1505 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1506 In a VPATH-build configuration, `make install' would install
1507 nobase_ files to wrong locations.
1509 - Fix a Perl `uninitialized value' diagnostic occurring when
1510 automake complains that a Texinfo file does not have a
1511 @setfilename statement.
1513 - Erase config.status.lineno during `make distclean'. This file
1514 can be created by config.status. Automake already knew about
1515 configure.lineno, but forgot config.status.lineno.
1517 - Distribute all files, even those which are built and installed
1518 conditionally. This change affects files listed in conditionally
1519 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1520 as well as those listed in conditionally defined dist_*_DATA,
1521 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1523 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1524 doesn't conform to POSIX.
1526 - Normalize help strings for configure variables and options added
1531 - Check for python2.4 in AM_PATH_PYTHON.
1533 * Spurious failures in test suite:
1535 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1536 tests/ltconv.test: fix failures with CVS Libtool.
1537 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1538 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1539 fix failures with old Texinfo versions.
1541 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1547 - The NEWS file is more verbose.
1551 - Autoconf 2.58 or greater is required.
1555 - Default source file names in the absence of a _SOURCES declaration
1556 are made by removing any target extension before appending `.c', so
1557 to make the libtool module `foo.la' from `foo.c', you only need to
1560 lib_LTLIBRARIES = foo.la
1561 foo_la_LDFLAGS = -module
1563 For backward compatibility, foo_la.c will be used instead of
1564 foo.c if this file exists or is the explicit target of a rule.
1565 However -Wobsolete will warn about this deprecated naming.
1567 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1568 of being hard-coded in each $(AR) invocation, so they can be
1569 substituted from configure.ac. This has been requested by people
1570 dealing with non-POSIX ar implementations.
1572 - New warning option: -Woverride. This will warn about any user
1573 target or variable definitions which override Automake
1576 - Texinfo rules back up and restore info files when makeinfo fails.
1578 - Texinfo rules now support the `html' target.
1579 Running this requires Texinfo 4.0 or greater.
1581 `html' is a new recursive target, so if your package mixes
1582 hand-crafted `Makefile.in's with Automake-generated
1583 `Makefile.in's, you should adjust the former to support (or
1584 ignore) this target so that `make html' recurses successfully. If
1585 you had a custom `html' rule in your `Makefile.am', it's better to
1586 rename it as `html-local', otherwise your rule will override
1587 Automake's new rule (you can check that by running `automake
1588 -Woverride') and that will stop the recursion to subdirectories.
1590 Last but not least, this `html' rule is declared PHONY, even when
1591 overridden. Fortunately, it appears that few packages use a
1592 non-PHONY `html' rule.
1594 - Any file which is m4_included from configure.ac will appear as a
1595 configure and Makefile.in dependency, and will be automatically
1598 - The rules for rebuilding Makefiles and Makefile.ins will now
1599 rebuild all Makefiles and all Makefile.ins at once when one of
1600 configure's dependencies has changed. This is considerably faster
1601 than previous implementations, where config.status and automake
1602 were run separately in each directory (this still happens when you
1603 change a Makefile.am locally, without touching configure.ac or
1604 friends). Doing this also solves a longstanding issue: these
1605 rebuild rules failed to work when adding new directories to the
1606 tree, forcing you to run automake manually.
1608 - For similar reasons, the rules to rebuild configure,
1609 config.status, and aclocal.m4 are now defined in all directories.
1610 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1611 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1612 should better define them in all directories. This is easily done
1613 using an AC_SUBST (make sure you prefix these dependencies with
1614 $(top_srcdir) since this variable will appear at different
1615 levels of the build tree).
1617 - aclocal will now use `m4_include' instead of copying local m4
1618 files into aclocal.m4. (Local m4 files are those you ship with
1619 your project, other files will be copied as usual.)
1621 Because m4_included files are automatically distributed, it means
1622 for most projects there is no point in EXTRA_DISTing the list of
1623 m4 files which are used. (You can probably get rid of
1624 m4/Makefile.am if you had one.)
1626 - aclocal will avoid touching aclocal.m4 when possible, so that
1627 Autom4te's cache isn't needlessly invalidated. This behavior can
1628 be switched off with the new `--force' option.
1630 - aclocal now uses Autoconf's --trace to detect macros which are
1631 actually used and will no longer include unused macros simply
1632 because they where mentioned. This was often the case for macros
1633 called conditionally.
1635 - New options no-dist and no-dist-gzip.
1637 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1638 py-compile, and ylwrap, now all understand --version and --help.
1640 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1641 links as part of the distclean target and including source files in
1644 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1645 argument. The latter can be used to override the default behavior
1646 (which is to abort).
1648 - Automake will exit with $? = 63 on version mismatch. (So does
1649 Autoconf 2.58) missing knows this, and in this case it will
1650 emulate the tools as if they were absent. Because older versions
1651 of Automake and Autoconf did not use this exit code, this change
1652 will only be useful in projects generated with future versions of
1655 - When using AC_CONFIG_FILES with multiple input files, Automake
1656 generates the first ".in" input file for which a ".am" exists.
1657 (Former versions would try to use only the first input file.)
1659 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1660 idiom to disable byte-compilation of lisp_LISP files, it is
1661 recommended that you switch to using lisp_DATA. Note that
1662 this is not strictly equivalent: lisp_DATA will install elisp
1663 files even if emacs is not installed, while *_LISP do not
1664 install anything unless emacs is found.
1666 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1667 available. This selection is achieved through the Makefile
1668 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1669 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1670 `$(install_sh) -m 0755 -d'.
1674 - Because `mkdir -p' is available on most platforms, and we can use
1675 `install-sh -d' when it is not, the use of the mkinstalldirs
1676 script is being phased out. `automake --add-missing' no longer
1677 installs it, and if you remove mkinstalldirs from your package,
1678 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1680 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1681 gettextize and autopoint will install it when needed. Automake
1682 will continue to define the $(mkinstalldirs) and to distribute
1683 mkinstalldirs when this script is in the source tree.
1685 - AM_PROG_CC_STDC is now empty. The content of this macro was
1686 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1687 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1688 renaming should be safe, even if you have to support several,
1689 versions of Automake, because AC_PROG_CC defines this variable
1690 since Autoconf 2.54.)
1692 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1693 variable to override the aclocal.m4 dependencies computed
1694 (inaccurately) by older versions of Automake. Because Automake
1695 now tracks configure's m4 dependencies accurately (see m4_include
1696 above), the use of ACLOCAL_M4_SOURCES should be considered
1697 obsolete and will be flagged as such when running `automake
1702 - Defining programs conditionally using Automake conditionals no
1703 longer leads to a combinatorial explosion. The following
1704 construct used to be troublesome when used with dozens of
1719 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1721 - Due to implementation constraints, previous versions of Automake
1722 proscribed multiple conditional definitions of some variables
1732 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1733 This restriction has been lifted, and these variables now
1734 support multiple conditional definitions as do other variables.
1736 - Cleanup the definitions of $(distdir) and $(top_distdir).
1737 $(top_distdir) now points to the root of the distribution
1738 directory created during `make dist', as it did in Automake 1.4,
1739 not to the root of the build tree as it did in intervening
1740 versions. Furthermore these two variables are now only defined in
1741 the top level Makefile, and passed to sub-directories when running
1744 - The --no-force option now correctly checks the Makefile.in's
1745 dependencies before deciding not to update it.
1747 - Do not assume that make files are called Makefile in cleaning rules.
1749 - Update .info files in the source tree, not in the build tree. This
1750 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1751 used to update these files in the build tree (previous versions did
1752 it in the source tree too), and it caused several problems, varying
1753 from mere annoyance to portability issues.
1755 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1756 when --add-missing and --force-missing are used. For backward
1757 compatibility --add-missing will continue to install COPYING (in
1758 `gnu' strictness) when none of these three files exist, but this
1759 use is deprecated: you should better choose a license yourself and
1760 install it once for all in your source tree (and in your code
1763 - Fix ylwrap so that it does not overwrite header files that haven't
1764 changed, as the inline rule already does.
1766 - User-defined rules override automake-defined rules for the same
1767 targets, even when rules do not have commands. This is not new
1768 (and was documented), however some of the automake-generated
1769 rules have escaped this principle in former Automake versions.
1770 Rules for the following targets are affected by this fix:
1772 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1773 info, info-am, install-data-am, install-exec-am, install-info,
1774 install-info-am, install-man, installcheck-am, maintainer-clean,
1775 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1776 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1778 Practically it means that an attempt to supplement the dependencies
1779 of some target, as in
1781 clean: my-clean-rule
1783 will now *silently override* the automake definition of the
1784 rule for this target. Running `automake -Woverride' will diagnose
1785 all such overriding definitions.
1787 It should be noted that almost all of these targets support a *-local
1788 variant that is meant to supplement the automake-defined rule
1789 (See node `Extending' in the manual). The above rule should
1792 clean-local: my-clean-rule
1794 These *-local targets have been documented since at least
1795 Automake 1.2, so you should not fear the change if you have
1796 to support multiple automake versions.
1800 - The Automake manual is now distributed under the terms of the GNU FDL.
1802 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1804 - core dumps are no longer removed by the cleaning rules. There are
1805 at least three reasons for this:
1806 1. These files should not be created by any build step,
1807 so their removal do not fit any of the cleaning rules.
1808 Actually, they may be precious to the developer.
1809 2. If such file is created during a build, then it's clearly a
1810 bug Automake should not hide. Not removing the file will
1811 cause `make distcheck' to complain about its presence.
1812 3. Operating systems have different naming conventions for
1813 core dump files. A core file on one system might be a
1814 completely legitimate data file on another system.
1816 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1817 defined by Automake. This means that any definition in the
1818 environment will be used, unless overridden in the Makefile.am or
1819 on the command line. The old behavior, where these variables were
1820 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1821 AC_ARG_VARing each variable from configure.ac.
1823 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1824 documented. (The is not a new feature, these variables have
1825 been there since at least Automake 1.4.)

1875 Bugs fixed in 1.7.4:
1876 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1877 the Emacs implementation)
1878 * Fix output of aclocal.m4 dependencies in subdirectories.
1879 * Use `mv -f' instead of `mv' in fastdep rules.
1880 * Upgrade mdate-sh to work on OS/2.
1881 * Don't byte-compile elisp files when ELCFILES is set empty.

1892 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1893 * Query distutils for `pythondir' and `pythonexecdir', instead of
1894 using an hardcoded path. This should allow builds on 64-bit
1895 distributions that usually use lib64/ instead of lib/.
1896 * AM_PATH_PYTHON will also search for python2.3.
1897 * elisp files are now built all at once instead of one by one. Besides
1898 incurring a speed-up, this is required to support interdependent elisp files.
1899 * Support for DJGPP:
1900 - `make distcheck' will now work in `_inst/' and `_build' instead
1901 of `=inst/' and `=build/'
1902 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1903 - install/uninstall `*.i[0-9][0-9]'-style info files
1904 - more changes that affect only the Automake package (not its output)
1905 * Fix some incompatibilities with upcoming perl-5.10.
1906 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1907 PACKAGE and VERSION.
1909 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1910 is troublesome with gcc and Solaris compilers. (PR/385)
1911 - makedepend mode: work with Libtool. (PR/385 too)
1913 * better support for unusual gettext setups, such as multiple po/ directories
1915 - Flag missing po/ and intl/ directories as warnings, not errors.
1916 - Disable these warnings if po/ does not exist.

1924 * Fix installation and uninstallation of Info files built in subdirectories.
1925 * Do not run `./configure --with-included-gettext' during `make distcheck'
1926 if AM_GNU_GETTEXT([external]) is used.
1927 * Correctly uninstall renamed man pages.
1928 * Do not strip escaped newline in variables defined in one condition
1929 and augmented in another condition.
1930 * Fix ansi2knr rules for LIBOBJS sources.
1931 * Clean all known Texinfo index files, not only those which appear to
1932 be used, because we cannot know which indexes are used in included files.
1933 (PR/375, Debian Bug #168671)
1934 * Honor only the first @setfilename seen in a Texinfo file.
1935 * Treat "required file X not found" diagnostics as errors (exit status 1).
1936 * Don't complain that a required file is not found when it is a Makefile
1938 * Don't use single suffix inference rules when building `.info'-less
1939 Info files, for the sake of Solaris make.
1940 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1941 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1942 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1943 * Fix building of deansified files from subdirectories. (PR/370)
1944 * Add missing `fi' in the .c->.obj rules.
1945 * Improve install-sh to work even when names contain spaces or certain
1946 (but not all) shell metachars.
1947 * Fix the following spurious failures in the test suite:
1948 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1949 * Noteworthy manual updates:
1950 - Augment the section about BUILT_SOURCES.
1951 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1953 Bugs fixed in 1.7.1:
1954 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1956 * Aclocal should now recognize macro names containing parentheses, e.g.
1957 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1958 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1960 * Install Python files even if they were built. (PR/369)
1961 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1962 version might not be defined in the latter. (PR/358)
1963 * Reorder arguments passed to a couple of commands, so things works
1964 when POSIXLY_CORRECT=1.
1965 * Fix a regex that can cause Perl to segfault on large input.
1967 * Fix distribution of packages that have some sources defined conditionally,
1968 as in the `Conditional compilation using Automake conditionals' example
1970 * Fix spurious test suite failures on IRIX.
1971 * Don't report a required variable as undefined if it has been
1972 defined conditionally for the "right" conditions.
1973 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1974 `make distcheck' fails.
1975 * Fix distribution of included Makefile fragment, so we don't create
1976 spurious directories in the distribution. (PR/366)
1977 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1980 * Autoconf 2.54 is required.
1981 * `aclocal' and `automake' will no longer warn about obsolete
1982 configure macros. This is done by `autoconf -Wobsolete'.
1983 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1984 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1985 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1986 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1987 `configure.ac' for you.
1988 * Support for per-program and per-library `_CPPFLAGS'.
1989 * New `ctags' target (builds CTAGS files).
1990 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1991 (see `automake --help' or the manual for a list of them).
1992 * Honor the WARNINGS environment variable.
1993 * Omit the call to depcomp when using gcc3: call the compiler directly.
1994 * A new option, std-options, tests that programs support --help and --version
1995 when `make installcheck' is run. This is enabled by --gnits.
1996 * Texinfo rules now support the `ps' and `pdf' targets.
1997 * Info files are now created in the build directory, not the source directory.
1998 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
2000 * `make distcheck' will enforce DESTDIR support by attempting
2002 * `+=' can be used in conditionals, even if the augmented variable
2003 was defined for another condition.
2004 * Makefile fragments (inserted with `include') are always distributed.
2005 * Use Autoconf's --trace interface to inspect configure.ac and get
2006 a more accurate view of it.
2007 * Add support for extending aclocal's default macro search path
2008 using a `dirlist' file within the aclocal directory.
2009 * automake --output-dir is deprecated.
2010 * The part of the distcheck target that checks whether uninstall actually
2011 removes all installed files has been moved in a separate target,
2012 distuninstallcheck, so it can be overridden easily.
2016 * Support for AM_INIT_GETTEXT([external])
2017 * Bug fixes, including:
2018 - Fix Automake's own `make install' so it works even if `ln' doesn't.

2036 - Don't choke on AM_LDFLAGS definitions.
2037 - Clean libtool objects from subdirectories.
2038 - Allow configure variables with reserved suffix and unknown prefix
2039 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
2040 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
2043 * Autoconf 2.52 is required.
2044 * automake no longer run libtoolize.
2045 This is the job of autoreconf (from GNU Autoconf).
2046 * `dist' generates all the archive flavors, as did `dist-all'.
2047 * `dist-gzip' generates the Gzip tar file only.
2048 * Combining Automake Makefile conditionals no longer lead to a combinatorial
2049 explosion. Makefile.in's keep a reasonable size.
2050 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
2051 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
2053 * `#line' of Lex and Yacc files are properly set.
2054 * EXTRA_DIST can contain generated directories.
2055 * Support for dot-less extensions in suffix rules.
2056 * The part of the distcheck target that checks whether distclean actually
2057 cleans all built files has been moved in a separate target, distcleancheck,
2058 so it can be overridden easily.
2059 * `make distcheck' will pass additional options defined in
2060 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
2061 * Fixed CDPATH portability problems, in particular for MacOS X.

2067 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
2068 (Note that "pkgname" is not "tarname", see the manual for details.)
2069 It is also possible to pass a list of global Automake options as
2070 first argument to this new form of AM_INIT_AUTOMAKE.
2071 * Compiler-based assembler is now called `CCAS'; people expected `AS'
2072 to be a real assembler.
