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37 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002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40 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002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 not try anymore 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
64 * Warnings and deprecations:
66 - Warnings in the 'obsolete' category are enabled by default both in
69 - Some testsuite weaknesses and spurious failures have been fixed.
71 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
75 * Miscellaneous changes:
77 - The '.m4' files provided by Automake does not define serial numbers
78 anymore. This should cause no difference in the behaviour of aclocal
81 - Some testsuite weaknesses and spurious failures have been fixed.
83 - There is initial support for automatic dependency tracking with the
84 Portland Group C/C++ compilers, thanks to the new new depmode 'pgcc'.
90 - Instead of renaming only self-references of files (typically for
91 #lines), ylwrap now also renames references to the other generated
92 files. This fixes support for GLR and C++ parsers from Bison (PR
93 automake/491 and automake bug#7648): 'parser.c' now properly
94 #includes 'parser.h' instead of 'y.tab.h'.
96 - Generated files unknown to ylwrap are now preserved. This fixes
97 C++ support for Bison (automake bug#7648): location.hh and the
98 like are no longer discarded.
100 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
104 * Warnings and deprecations:
106 - Automake now issues a warning (in the 'portability' category) if
107 'configure.in' is used instead of 'configure.ac' as the Autoconf
108 input file. Such a warning will also be present in the next
109 Autoconf version (2.70).
113 - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
114 order (as done by the other recursive rules), rather than in the
115 inverse order. They used to do that in order to work a round a
116 limitation in an older implementation of the automatic dependency
117 tracking support, but that limitation had been lifted years ago
118 already, when the automatic dependency tracking based on side-effects
119 of compilation had been introduced.
121 - Cleaning rules for compiled objects (both "plain" and libtool) work
122 better when subdir objects are involved, not triggering a distinct
123 'rm' invocation for each such object. They do so by removing *any*
124 compiled object file that is in the same directory of a subdir
125 object. See automake bug#10697.
127 * Silent rules support:
129 - A new predefined $(AM_V_P) make variable is provided; it expands
130 to a shell conditional that can be used in recipes to know whether
131 make is being run in silent or verbose mode.
133 Bugs fixed in 1.12.2:
135 * SECURITY VULNERABILITIES!
137 - The 'distcheck' recipe no longer grants temporary world-write
138 permissions on the extracted distdir. Even if such rights were
139 only granted for a vanishingly small time window, the implied
140 race condition proved to be enough to allow a local attacker
141 to run arbitrary code with the privileges of the user running
142 "make distcheck". This is CVE-2012-3386.
144 * Long-standing bugs:
146 - The "recheck" targets behaves better in the face of build failures
147 related to previously failed tests. For example, if a test is a
148 compiled program that must be rerun by "make recheck", and its
149 compilation fails, it will still be rerun by further "make recheck"
150 invocations. See automake bug#11791.
152 * Bugs introduced by 1.12.1:
154 - Automake provides once again the '$(mkdir_p)' make variable and the
155 '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
156 for better backward-compatibility.
158 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
162 * New supported languages:
164 - Support for Objective C++ has been added; it should work similarly to
165 the support for Objective C.
167 * Deprecated obsolescent features:
169 - Use of the long-deprecated two- and three-arguments invocation forms
170 of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
171 category. Starting from some future major Automake release (likely
172 post-1.13), such usages won't be allowed anymore.
174 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
175 now deprecated (its use triggers a warning in the 'obsolete' category).
176 It will be removed in the next major Automake release (1.13).
178 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
179 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
180 m4 macro are deprecated, eliciting a warning in the 'obsolete'
183 * Miscellaneous changes:
185 - The Automake test cases now require a proper POSIX-conforming shell.
186 Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) won't be
187 accepted anymore. In most cases, the user shouldn't have to specify
188 such POSIX shell explicitly, since it will be looked up at configure
189 time. Still, when this lookup fails, or when the user wants to
190 override its conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be
191 used (pointing to the shell that will be used to run the Automake
194 Bugs fixed in 1.12.1:
196 * Bugs introduced by 1.12:
198 - Several weaknesses in Automake's own build system and test suite
201 * Bugs introduced by 1.11.3:
203 - When given non-option arguments, aclocal rejects them, instead of
204 silently ignoring them.
206 * Long-standing bugs:
208 - When the 'color-tests' option is in use, forcing of colored testsuite
209 output through "AM_COLOR_TESTS=always" works even if the terminal is
210 a non-ANSI one, i.e., if the TERM environment variable has a value of
213 - Several inefficiencies and poor performances in the implementation
214 of the parallel-tests 'check' and 'recheck' targets have been fixed.
216 - The post-processing of output "#line" directives done the ylwrap
217 script is more faithful w.r.t. files in a subdirectory; for example,
218 if the processed file is "src/grammar.y", ylwrap will correctly
219 produce directives like:
220 #line 7 "src/grammar.y"
225 * Bugs with new Perl versions:
227 - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
229 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
233 * Obsolete features removed:
235 - The never documented nor truly used script 'acinstall' has been
238 - Support for automatic de-ANSI-fication has been removed.
240 - The support for the "obscure" multilib feature has been removed
241 from Automake core (but remains available in the 'contrib/'
242 directory of the Automake distribution).
244 - Support for ".log -> .html" conversion and the check-html and
245 recheck-html targets has been removed from Automake core (but
246 remains available in the 'contrib/' directory of the Automake
249 - The deprecated 'lzma' compression format for distribution archives
250 has been removed, in favor of 'xz' and 'lzip'.
252 - The obsolete AM_WITH_REGEX macro has been removed.
254 - The long-deprecated options '--output-dir', '--Werror' and
255 '--Wno-error' have been removed.
257 - The chapter on the history of Automake has been moved out of the
258 reference manual, into a new dedicated Texinfo file.
262 - New 'cscope' target to build a cscope database for the source tree.
264 * Changes to Automake-generated testsuite harnesses:
266 - The new automake option 'serial-tests' has been introduced. It can
267 be used to explicitly instruct automake to use the older serial
268 testsuite harness. This is still the default at the moment, but it
269 might change in future versions.
271 - The 'recheck' target (provided by the parallel testsuite harness) now
272 depends on the 'all' target. This allows for a better user-experience
273 in test-driven development. See automake bug#11252.
275 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
276 and unexpected or internal error, or a failure to set up the test case
277 scenario) have their outcome reported as an 'ERROR' now. Previous
278 versions of automake reported such an outcome as a 'FAIL' (the only
279 difference with normal failures being that hard errors were counted
280 as failures even when the test originating them was listed in
283 - The testsuite summary displayed by the parallel-test harness has a
284 completely new format, that always list the numbers of passed, failed,
285 xfailed, xpassed, skipped and errored tests, even when these numbers
286 are zero (but using smart coloring when the color-tests option is in
289 - The default testsuite driver offered by the 'parallel-tests' option is
290 now implemented (partly at least) with the help of automake-provided
291 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
292 on code in the generated Makefile.in.
293 This has two noteworthy implications. The first one is that projects
294 using the 'parallel-tests' option should now either run automake with
295 the '--add-missing' option, or manually copy the 'test-driver' script
296 into their tree. The second, and more important, implication is that
297 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
298 not be used anymore to define a test runner, and the command specified
299 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
300 program or script. For example, this is still a valid usage (albeit
303 TESTS_ENVIRONMENT = \
304 if test -n '$(STRICT_TESTS)'; then \
305 maybe_errexit='-e'; \
309 LOG_COMPILER = $(SHELL) $$maybe_errexit
311 while this is not anymore:
313 TESTS_ENVIRONMENT = \
314 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
318 TESTS_ENVIRONMENT = \
319 run_with_perl_or_shell () \
321 if grep -q '^#!.*perl' $$1; then
327 LOG_COMPILER = run_with_perl_or_shell
329 - The package authors can now use customary testsuite drivers within
330 the framework provided by the 'parallel-tests' testsuite harness.
331 Consistently with the existing syntax, this can be done by defining
332 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
334 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
335 to redirect/define file descriptors used by the test scripts.
337 - The parallel-tests harness generates now, in addition the '.log' files
338 holding the output produced by the test scripts, a new set of '.trs'
339 files, holding "metadata" derived by the execution of the test scripts;
340 among such metadata are the outcomes of the test cases run by a script.
342 - Initial and still experimental support for the TAP test protocol is
345 * Changes to Yacc and Lex support:
347 - C source and header files derived from non-distributed Yacc and/or
348 Lex sources are now removed by a simple "make clean" (while they were
349 previously removed only by "make maintainer-clean").
351 - Slightly backward-incompatible change, relevant only for use of Yacc
352 with C++: the extensions of the header files produced by the Yacc
353 rules are now modelled after the extension of the corresponding
354 sources. For example, yacc files named "foo.y++" and "bar.yy" will
355 produce header files named "foo.h++" and "bar.hh" respectively, where
356 they would have previously produced header files named simply "foo.h"
357 and "bar.h". This change offers better compatibility with 'bison -o'.
359 * Miscellaneous changes:
361 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
362 rather than 1, if the vala compiler found is too old.
364 - The build system of Automake itself now avoids the use of make
365 recursion as much as possible.
367 - Automake now prefers to quote 'like this' or "like this", rather
368 than `like this', in diagnostic message and generated Makefiles,
369 to accommodate the new GNU Coding Standards recommendations.
371 - Automake has a new option '--print-libdir' that prints the path of the
372 directory containing the Automake-provided scripts and data files.
374 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
376 - The rules to create pdf, dvi and ps output from Texinfo files now
377 works better with modern 'texi2dvi' script, by explicitly passing
378 it the '--clean' option to ensure stray auxiliary files are not
379 left to clutter the build directory.
381 - Automake can now generate silenced rules for texinfo outputs.
383 - Some auxiliary files that are automatically distributed by Automake
384 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
385 C sources) might now be listed in the DIST_COMMON variable in many
386 Makefile.in files, rather than in the top-level one.
388 - Messages of types warning or error from 'automake' and 'aclocal'
389 are now prefixed with the respective type, and presence of -Werror
392 - Automake's early configure-time sanity check now tries to avoid
393 sleeping for a second, which slowed down cached configure runs
394 noticeably. In that case, it will check back at the end of the
395 configure script to ensure that at least one second has passed, to
396 avoid time stamp issues with makefile rules rerunning autotools
399 - The warnings in the category 'extra-portability' are now enabled by
400 '-Wall'. In previous versions, one has to use '-Wextra-portability'
405 - Various minor bugfixes for recent or long-standing bugs.
407 * Bugs introduced by 1.11:
409 - The AM_COND_IF macro also works if the shell expression for the
410 conditional is no longer valid for the condition.
412 - The automake-provided parallel testsuite harness does not fail anymore
413 with BSD make used in parallel mode when there are test scripts in a
414 subdirectory, like in:
416 TESTS = sub/foo.test sub/bar.test
418 * Long-standing bugs:
420 - Automake's own build system finally have a real "installcheck" target.
422 - Vala-related cleanup rules are now more complete, and work better in
425 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
426 now automatically distributed also if the directory of the auxiliary
427 files coincides with the top-level directory.
429 - Automake now detects the presence of the '-d' flag in the various
430 '*YFLAGS' variables even when their definitions involve indirections
431 through other variables, such as in:
433 AM_YFLAGS = $(foo_opts)
435 - Automake now complains if a '*YFLAGS' variable has any conditional
436 content, not only a conditional definition.
438 - Explicit enabling and/or disabling of Automake warning categories
439 through the '-W...' options now always takes precedence over the
440 implicit warning level implied by Automake strictness (foreign, gnu
441 or gnits), regardless of the order in which such strictness and
442 warning flags appear. For example, a setting like:
443 AUTOMAKE_OPTIONS = -Wall --foreign
444 will cause the warnings in category 'portability' to be enabled, even
445 if those warnings are by default disabled in 'foreign' strictness.
447 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
449 Bugs fixed in 1.11.5:
451 * Bugs introduced by 1.11.3:
453 - Vala files with '.vapi' extension are now recognized and handled
454 correctly again. See automake bug#11222.
456 - Vala support work again for projects that contain some program
457 built from '.vala' (and possibly '.c') sources and some other
458 program built from '.c' sources *only*. See automake bug#11229.
460 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
464 * Miscellaneous changes:
466 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
467 symbol index) modifiers as well as the "s" action, as the symbol index
468 is created unconditionally by Microsoft lib. Also, the "q" (quick)
469 action is now a synonym for "r" (replace). Also, the script has been
470 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
472 - When the 'compile' script is used to wrap MSVC, it now accepts an
473 optional space between the -I, -L and -l options and their respective
474 arguments, for better POSIX compliance.
476 - There is an initial, experimental support for automatic dependency
477 tracking with tcc (the Tiny C Compiler). Its associated depmode is
478 currently recognized as "icc" (but this and other details are likely
479 to change in future versions).
481 - Automatic dependency tracking now works also with the IBM XL C/C++
482 compilers, thanks to the new new depmode 'xlc'.
484 Bugs fixed in 1.11.4:
486 * Bugs introduced by 1.11.2:
488 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
489 don't cause spurious failures upon "make install" anymore.
491 - The user can now instruct the 'uninstall-info' rule not to update
492 the '${infodir}/dir' file by exporting the environment variable
493 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
494 with how the 'install-info' rule operates since automake 1.11.2.
496 * Long-standing bugs:
498 - It is now possible for a foo_SOURCES variable to hold Vala sources
499 together with C header files, as well as with sources and headers for
500 other supported languages (e.g., C++). Previously, only mixing C and
501 Vala sources was supported.
503 - If "aclocal --install" is used, and the first directory specified with
504 '-I' is non-existent, aclocal will now create it before trying to copy
507 - An empty declaration of a "foo_PRIMARY" don't cause anymore the
508 generated install rules to create an empty $(foodir) directory;
509 for example, if Makefile.am contains something like:
513 pkglibexec_SCRIPTS += bar.sh
516 the $(pkglibexec) directory will not be created upon "make install".
518 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
522 * Miscellaneous changes:
524 - Automake's own build system is more silent by default, making use of
525 the 'silent-rules' option.
527 - The master copy of the `gnupload' script is now maintained in gnulib,
530 - The `missing' script doesn't try to wrap calls to `tar' anymore.
532 - "make dist" doesn't wrap `tar' invocations with the `missing' script
533 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
534 shouldn't be using BTW ;-) does not invoke the missing script anymore
535 to wrap tar, but simply invokes the `tar' program itself.
537 - "make dist" can now create lzip-compressed tarballs.
539 - In the Automake info documentation, the Top node and the nodes about
540 the invocation of the automake and aclocal programs have been renamed;
541 now, calling "info automake" will open the Top node, while calling
542 "info automake-invocation" and "info aclocal-invocation" will access
543 the nodes about the invocation of respectively automake and aclocal.
545 - Automake is now distributed as a gzip-compressed and an xz-compressed
546 tarball. Previously, bzip2 was used instead of xz.
548 - The last relics of Python 1.5 support have been removed from the
549 AM_PATH_PYTHON macro.
551 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
552 and adds them to the normal list of dependencies, but without
553 overwriting the foo_DEPENDENCIES variable, which is normally computed
556 Bugs fixed in 1.11.3:
558 * Bugs introduced by 1.11.2:
560 - Automake now correctly recognizes the prefix/primary combination
561 `pkglibexec_SCRIPTS' as valid.
563 - The parallel-tests harness doesn't trip anymore on sed implementations
564 with stricter limits on the length of input lines (problem seen at
567 * Long-standing bugs:
569 - The "deleted header file problem" for *.am files is avoided by stub
570 rules. This allows `make' to trigger a rerun of `automake' also if
571 some previously needed `.am' file has been removed.
573 - The `silent-rules' option now generates working makefiles even
574 for the uncommon `make' implementations that do not support the
575 nested-variables extension to POSIX 2008. For such `make'
576 implementations, whether a build is silent is determined at
577 configure time, and cannot be overridden at make time with
578 `make V=0' or `make V=1'.
580 - Vala support now works better in VPATH setups.
582 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
586 * Changes to aclocal:
588 - The `--acdir' option is deprecated. Now you should use the new options
589 `--automake-acdir' and `--system-acdir' instead.
591 - The `ACLOCAL_PATH' environment variable is now interpreted as a
592 colon-separated list of additional directories to search after the
593 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
594 and before the system acdir (by default ${prefix}/share/aclocal).
596 * Miscellaneous changes:
598 - The Automake support for automatic de-ANSI-fication has been
599 deprecated. It will probably be removed in the next major Automake
602 - The `lzma' compression scheme and associated automake option `dist-lzma'
603 is obsoleted by `xz' and `dist-xz' due to upstream changes.
605 - You may adjust the compression options used in dist-xz and dist-bzip2.
606 The default is now merely -e for xz, but still -9 for bzip; you may
607 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
608 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
610 - The `compile' script now converts some options for MSVC for a better
611 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
613 - The py-compile script now accepts empty arguments passed to the options
614 `--destdir' and `--basedir', and complains about unrecognized options.
615 Moreover, a non-option argument or a special `--' argument terminates
618 - A developer that needs to pass specific flags to configure at "make
619 distcheck" time can now, and indeed is advised to, do so by defining
620 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
621 instead of the old DISTCHECK_CONFIGURE_FLAGS.
622 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
623 user; still, the old Makefile.am files that used to define it will
624 still continue to work as before.
626 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
627 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
628 This new macro is required for LIBRARIES and LTLIBRARIES when automake
629 is run with -Wextra-portability and -Werror.
631 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
632 file generated by automake-provided rules by defining the special make
633 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
635 - The `install-info' rule can now be instructed not to create/update
636 the `${infodir}/dir' file, by exporting the new environment variable
637 `AM_UPDATE_INFO_DIR' to the value "no".
639 Bugs fixed in 1.11.2:
641 * Bugs introduced by 1.11:
643 - The parallel-tests driver no longer produces erroneous results with
644 Tru64/OSF 5.1 sh upon unreadable log files.
646 - The `parallel-tests' test driver does not report spurious successes
647 when used with concurrent FreeBSD make (e.g., "make check -j3").
649 - When the parallel-tests driver is in use, automake now explicitly
650 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
651 instead of issuing confusing and apparently unrelated error messages
652 (e.g., "non-POSIX variable name", "bad characters in variable name",
653 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
654 silently producing broken `Makefile.in' files.
656 - The `silent-rules' option now truly silences all compile rules, even
657 when dependency tracking is disabled. Also, when `silent-rules' is
658 not used, `make' output no longer contains spurious backslash-only
659 lines, thus once again matching what Automake did before 1.11.
661 - The AM_COND_IF macro also works if the shell expression for the
662 conditional is no longer valid for the condition.
664 * Long-standing bugs:
666 - The order of Yacc and Lex flags is fixed to be consistent with other
667 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
668 $(LFLAGS), so that the user variables override the developer variables.
670 - "make distcheck" now correctly complains also when "make uninstall"
671 leaves one and only one file installed in $(prefix).
673 - A "make uninstall" issued before a "make install", or after a mere
674 "make install-data" or a mere "make install-exec" does not spuriously
677 - Automake now warns about more primary/directory invalid combinations,
678 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
680 - Rules generated by Automake now try harder to not change any files when
681 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
682 Yacc source files and the rule to update config.h.
684 - Several scripts and the parallel-tests testsuite driver now exit with
685 the right exit status upon receiving a signal.
687 - A per-Makefile.am setting of -Werror does not erroneously carry over
688 to the handling of other Makefile.am files.
690 - The code for automatic dependency tracking works around a Solaris
691 make bug triggered by sources containing repeated slashes when the
692 `subdir-objects' option was used.
694 - The makedepend and hp depmodes now work better with VPATH builds.
696 - Java sources specified with check_JAVA are no longer compiled for
697 "make all", but only for "make check".
699 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
700 and error out if `javadir' is undefined, instead of silently producing
701 a broken Makefile.in.
703 - aclocal and automake now honour the configure-time definitions of
704 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
706 - The `install-info' recipe no longer tries to guess whether the
707 `install-info' program is from Debian or from GNU, and adaptively
708 change its behaviour; this has proven to be frail and easy to
711 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
713 Bugs fixed in 1.11.1:
715 - Lots of minor bugfixes.
717 * Bugs introduced by 1.11:
719 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
720 trailing white space in the test list (`TESTS = foo $(EMPTY)').
722 * Long standing bugs:
724 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
725 even if the `--prefix' argument pointed outside of a system directory.
726 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
727 `get_python_lib' function if it points outside the configured prefix,
728 unless the `--prefix' argument was either `/usr' or below `/System'.
730 - The testsuite does not try to change the mode of `ltmain.sh' files from
731 a Libtool installation (symlinked to test directories) any more.
733 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
734 tools are preferred in a cross-compile setup.
736 - The distribution is tarred up with mode 755 now by the `dist*' targets.
737 This fixes a race condition where untrusted users could modify files
738 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
739 build directory was world-searchable. This is CVE-2009-4029.
741 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
745 * Version requirements:
747 - Autoconf 2.62 or greater is required.
749 * Changes to aclocal:
751 - The autoconf version check implemented by aclocal in aclocal.m4
752 (and new in Automake 1.10) is degraded to a warning. This helps
753 in the common case where the Autoconf versions used are compatible.
755 * Changes to automake:
757 - The automake program can run multiple threads for creating most
758 Makefile.in files concurrently, if at least Perl 5.7.2 is available
759 with interpreter-based threads enabled. Set the environment variable
760 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
761 enable this experimental feature.
763 * Changes to Libtool support:
765 - Libtool generic flags are now passed to the install and uninstall
768 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
769 config.lt is removed correctly now.
773 - subdir-object mode works now with Fortran (F77, FC, preprocessed
774 Fortran, and Ratfor).
776 - For files with extension .f90, .f95, .f03, or .f08, the flag
777 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
779 - Files with extension .sx are also treated as preprocessed assembler.
781 - The default source file extension (.c) can be overridden with
782 AM_DEFAULT_SOURCE_EXT now.
784 - Python 3.0 is supported now, Python releases prior to 2.0 are no
787 - AM_PATH_PYTHON honors python's idea about the site directory.
789 - There is initial support for the Vala programming language, when using
792 * Miscellaneous changes:
794 - Automake development is done in a git repository on Savannah now, see
796 http://git.sv.gnu.org/gitweb/?p=automake.git
798 A read-only CVS mirror is provided at
800 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
801 checkout -d automake HEAD
803 - "make dist" can now create xz-compressed tarballs,
804 as well as (deprecated?) lzma-compressed tarballs.
806 - `automake --add-missing' will by default install the GPLv3 file as
807 COPYING if it is missing. It will also warn that the license file
808 should be added to source control. Note that Automake will never
809 overwrite an existing COPYING file, even when the `--force-missing'
812 - The manual is now distributed under the terms of the GNU FDL 1.3.
814 - Automake ships and installs man pages for automake and aclocal now.
816 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
818 - install-sh supports -C, which does not update the installed file
819 (and its time stamps) if the contents did not change.
821 - The `gnupload' script has been revamped.
823 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
825 - The targets `install' and `uninstall' are more efficient now, in that
826 for example multiple files from one Automake variable such as
827 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
828 invocation if they do not have to be renamed.
830 Both install and uninstall may sometimes enter (`cd' into) the target
831 installation directory now, when no build-local scripts are used.
833 Both install and uninstall do not fail anymore but do nothing if an
834 installation directory variable like `bindir' is set to the empty string.
836 For built-in rules, `make install' now fails reliably if installation
837 of a file failed. Conversely, `make uninstall' even succeeds when
838 issued multiple times.
840 These changes may need some adjustments from users: For example,
841 some `install' programs refuse to install multiple copies of the
842 same file in one invocation, so you may need to remove duplicate
843 entries from file lists.
845 Also, within one set of files, say, nobase_data_DATA, the order of
846 installation may be changed, or even unstable among different hosts,
847 due to the use of associative arrays in awk. The increased use of
848 awk matches a similar move in Autoconf to provide for better scaling.
850 Further, most undocumented per-rule install command variables such as
851 binSCRIPT_INSTALL have been removed because they are not needed any
852 more. Packages which use them should be using the appropriate one of
853 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
854 counterpart, depending on the type of files and the need for automatic
855 target directory creation.
857 - The "deleted header file problem" for *.m4 files is avoided by
858 stub rules. This allows `make' to trigger a rerun of `aclocal'
859 also if some previously needed macro file has been removed.
861 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
862 an otherwise up to date tree.
864 - The `color-tests' option causes colored test result output on terminals.
866 - The `parallel-tests' option enables a new test driver that allows for
867 parallel test execution, inter-test dependencies, lazy test execution
868 for unit-testing, re-testing only failed tests, and formatted result output
869 as RST (reStructuredText) and HTML. Enabling this option may require some
870 changes to your test suite setup; see the manual for details.
872 - The `silent-rules' option enables Linux kernel-style silent build output.
873 This option requires the widely supported but non-POSIX `make' feature
874 of recursive variable expansion, so do not use it if your package needs
875 to build with `make' implementations that do not support it.
877 To enable less verbose build output, the developer has to use the Automake
878 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
879 macro. The user may then set the default verbosity by passing the
880 `--enable-silent-rules' option to `configure'. At `make' run time, this
881 default may be overridden using `make V=0' for less verbose, and `make V=1'
882 for backward-compatible verbose output.
884 - New prefix `notrans_' for manpages which should not be transformed
885 by --program-transform.
887 - New macro AM_COND_IF for conditional evaluation and conditional
890 - For AC_CONFIG_LINKS, if source and destination are equal, do not
891 remove the file in a non-VPATH build. Such setups work with Autoconf
894 - AM_MAINTAINER_MODE now allows for an optional argument specifying
897 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
898 useful especially for multi-line values.
900 - Automake's early configure-time sanity check now diagnoses an
901 unsafe absolute source directory name and makes configure fail.
903 - The Automake macros and rules cope better with whitespace in the
904 current directory name, as long as the relative path to `configure'
905 does not contain whitespace. To this end, the values of `$(MISSING)'
906 and `$(install_sh)' may contain suitable quoting, and their expansion
907 might need `eval'uation if used outside of a makefile. These
908 undocumented variables may be used in several documented macros such
909 as $(AUTOCONF) or $(MAKEINFO).
913 * Long-standing bugs:
915 - Fix aix dependency tracking for libtool objects.
917 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
918 unnecessary use of the `compile' script.
920 - For nobase_*_LTLIBRARIES with nonempty directory components, the
921 correct `-rpath' argument is used now.
923 - `config.status --file=Makefile depfiles' now also works with the
924 extra quoting used internally by Autoconf 2.62 and newer
925 (it used to work only without the `--file=' bit).
927 - The `missing' script works better with versioned tool names.
929 - Semantics for `missing help2man' have been revamped:
931 Previously, if `help2man' was not present, `missing help2man' would have
932 the following semantics: if some man page was out of date but present, then
933 a warning would be printed, but the exit status was 0. If the man page was
934 not present at all, then `missing' would create a replacement man page
935 containing an error message, and exit with a status of 2. This does not play
936 well with `make': the next run will see this particular man page as being up
937 to date, and will only error out on the next generated man page, if any;
938 repeat until all pages are done. This was not desirable.
940 These are the new semantics: if some man page is not present, and help2man
941 is not either, then `missing' will warn and generate the replacement page
942 containing the error message, but exit successfully. However, `make dist'
943 will ensure that no such bogus man pages are packaged into a tarball.
945 - Targets provided by automake behave better with `make -n', in that they
946 take care not to create files.
948 - `config.status Makefile... depfiles' works fine again in the presence of
949 disabled dependency tracking.
951 - The default no-op recursive rules for these targets also work with BSD make
952 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
954 - `make distcheck' works also when both a directory and some file below it
955 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
957 - Texinfo dvi, ps, pdf, and html output files are not removed upon
958 `make mostlyclean' any more; only the LaTeX by-products are.
960 - Renamed objects also work with the `subdir-objects' option and
961 source file languages which Automake does not know itself.
963 - `automake' now correctly complains about variable assignments which are
964 preceded by a comment, extend over multiple lines with backslash-escaped
965 newlines, and end in a comment sign. Previous versions would silently
966 and wrongly ignore such assignments completely.
968 * Bugs introduced by 1.10:
970 - Fix output of dummy dependency files in presence of post-processed
971 Makefile.in's again, but also cope with long lines.
973 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
974 that have been declared as programs in the same Makefile.
975 This is for consistency with the analogous change to TESTS in 1.10.
977 - Fix order of standard includes to again be `-I. -I$(srcdir)',
978 followed by directories containing config headers.
980 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
984 * Version requirements:
986 - Autoconf 2.60 or greater is required.
988 - Perl 5.6 or greater is required.
990 * Changes to aclocal:
992 - aclocal now also supports -Wmumble and -Wno-mumble options.
994 - `dirlist' entries (for the aclocal search path) may use shell
995 wildcards such as `*', `?', or `[...]'.
997 - aclocal supports an --install option that will cause system-wide
998 third-party macros to be installed in the local directory
999 specified with the first -I flag. This option also uses #serial
1000 lines in M4 files to upgrade local macros.
1002 The new aclocal options --dry-run and --diff help to review changes
1003 before they are installed.
1005 - aclocal now outputs an autoconf version check in aclocal.m4 in
1006 projects using automake.
1008 For a few years, automake and aclocal have been calling autoconf
1009 (or its underlying engine autom4te) to accurately retrieve the
1010 data they need from configure.ac and its siblings. Doing so can
1011 only work if all autotools use the same version of autoconf. For
1012 instance a Makefile.in generated by automake for one version of
1013 autoconf may stop working if configure is regenerated with another
1014 version of autoconf, and vice versa.
1016 This new version check ensures that the whole build system has
1017 been generated using the same autoconf version.
1019 * Support for new Autoconf macros:
1021 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
1023 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
1024 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
1025 in different directories. However, only one instance of such a
1026 library objects directory is supported.
1028 * Change to Libtool support:
1030 - Libtool generic flags (those that go before the --mode=MODE option)
1031 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
1033 * Yacc and Lex changes:
1035 - The rebuild rules for distributed Yacc and Lex output will avoid
1036 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
1039 - ylwrap is now always used for lex and yacc source files,
1040 regardless of whether there is more than one source per directory.
1042 * Languages changes:
1044 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
1045 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
1046 tracking, unlike non-preprocessed assembler (*.s).
1048 - subdir-object mode works now with Assembler. Automake assumes
1049 that the compiler understands `-c -o'.
1051 - Preprocessed assembler (*.S) compilation now also honors
1052 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
1054 - Improved support for Objective C:
1055 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
1056 - A new section of the manual documents the support.
1058 - New support for Unified Parallel C:
1059 - AM_PROG_UPC looks for a UPC compiler.
1060 - A new section of the manual documents the support.
1062 - Per-target flags are now correctly handled in link rules.
1064 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
1065 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
1066 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
1067 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
1069 The fix for compiler flags (i.e., using maude_CFLAGS instead of
1070 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
1071 is expected to work (and actually works during compilation).
1073 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
1074 "in addition to" breaks backward compatibility with older versions.
1075 If your package used both variables, as in
1077 AM_LDFLAGS = common flags
1078 bin_PROGRAMS = a b c
1079 a_LDFLAGS = more flags
1082 and assumed *_LDFLAGS would sum up, you should rewrite it as
1084 AM_LDFLAGS = common flags
1085 bin_PROGRAMS = a b c
1086 a_LDFLAGS = $(AM_LDFLAGS) more flags
1089 This new behavior of *_LDFLAGS is more coherent with other
1090 per-target variables, and the way *_LDFLAGS variables were
1091 considered internally.
1093 * New installation targets:
1095 - New targets mandated by GNU Coding Standards:
1100 By default they will only install Texinfo manuals.
1101 You can customize them with *-local variants:
1107 - The undocumented recursive target `uninstall-info' no longer exists.
1108 (`uninstall' is in charge of removing all possible documentation
1109 flavors, including optional formats such as dvi, ps, or info even
1110 when `no-installinfo' is used.)
1112 * Miscellaneous changes:
1114 - Automake no longer complains if input files for AC_CONFIG_FILES
1115 are specified using shell variables.
1117 - clean, distribution, or rebuild rules are normally disabled for
1118 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
1119 AC_CONFIG_LINK specified using shell variables. However, if these
1120 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
1121 be able to output rules anyway.
1122 (See the Automake documentation for AC_CONFIG_FILES.)
1124 - $(EXEEXT) is automatically appended to filenames of TESTS
1125 that have been declared as programs in the same Makefile.
1126 This is mostly useful when some check_PROGRAMS are listed in TESTS.
1128 - `-Wportability' has finally been turned on by default for `gnu' and
1129 `gnits' strictness. This means, automake will complain about %-rules
1130 or $(GNU Make functions) unless you switch to `foreign' strictness or
1131 use `-Wno-portability'.
1133 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
1134 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
1135 $(mkdir_p) variable is still defined (to the same value as
1136 $(MKDIR_P)) but should be considered obsolete. If you are using
1137 $(mkdir_p) in some of your rules, please plan to update them to
1138 $(MKDIR_P) at some point.
1140 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
1141 They still work in this release, but may be withdrawn in a future one.
1143 - Inline compilation rules for gcc3-style dependency tracking are
1146 - Automake installs a "Hello World!" example package in $(docdir).
1147 This example is used throughout the new "Autotools Introduction"
1148 chapter of the manual.
1150 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1154 * Makefile.in bloat reduction:
1156 - Inference rules are used to compile sources in subdirectories when
1157 the `subdir-objects' option is used and no per-target flags are
1158 used. This should reduce the size of some projects a lot, because
1159 Automake used to output an explicit rule for each such object in
1162 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1163 object that must be built with explicit rules. It just outputs
1164 the rules required to build the kind of object considered: either
1165 the two .o and .obj rules for usual objects, or the .lo rule for
1168 * Change to Libtool support:
1170 - Libtool tags are used with libtool versions that support them.
1171 (I.e., with Libtool 1.5 or greater.)
1173 - Automake is now able to handle setups where a libtool library is
1174 conditionally installed in different directories, as in
1177 lib_LTLIBRARIES = liba.la
1179 pkglib_LTLIBRARIES = liba.la
1181 liba_la_SOURCES = ...
1183 * Changes to aclocal:
1185 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1186 really evaluated, before it decides to include them in aclocal.m4.
1187 This solves nasty problems with conditional redefinitions of
1188 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1189 *.m4 files to be included in any project using these macros.
1190 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1191 most famous instance of this bug.)
1193 - Do not complain about missing conditionally AC_REQUIREd macros
1194 that are not actually used. In 1.8.x aclocal would correctly
1195 determine which of these macros were really needed (and include
1196 only these in the package); unfortunately it would also require
1197 all of them to be present in order to run. This created
1198 situations were aclocal would not work on a tarball distributing
1199 all the macros it uses. For instance running aclocal on a project
1200 containing only the subset of the Gettext macros in use by the
1201 project did not work, because gettext conditionally requires other
1204 * Portability improvements:
1206 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1207 tar-pax. The new option filename-length-max=99 helps diagnosing
1208 filenames that are too long for tar-v7. (PR/414)
1210 - Variables aumented with `+=' are now automatically flattened (i.e.,
1211 trailing backslashes removed) and then wrapped around 80 colummns
1212 (adding trailing backslashes). In previous versions, a long series
1218 would result in a single-line definition of VAR that could possibly
1219 exceed the maximum line length of some make implementations.
1221 Non-augmented variables are still output as they are defined in
1226 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1227 Works the same as the old Fortran 77 implementation; just replace
1228 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1229 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1231 - Support for conditional _LISP.
1233 - Support for conditional -hook and -local rules (PR/428).
1235 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1237 - Automake will not write any Makefile.ins after the first error it
1238 encounters. The previous Makefile.ins (if any) will be left in
1239 place. (Warnings will not prevent output, but remember they can
1240 be turned into errors with -Werror.)
1242 - The restriction that SUBDIRS must contain direct children is gone.
1245 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1246 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1248 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1250 Bugs fixed in 1.8.5:
1252 * Long-standing bugs:
1254 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1255 so that `make distclean' and `make maintainer-clean' can work.
1257 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1259 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1261 - Polish diagnostic when no input file is found.
1263 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1265 Bugs fixed in 1.8.4:
1267 * Long-standing bugs:
1269 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1270 overridden by the user.
1272 - Honor PATH_SEPARATOR in various places of the Automake package, for
1275 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1278 - Fix install-sh so it can install the `mv' binary... using `mv'.
1280 - Fix tru64 dependency tracking for libtool objects.
1282 - Work around Exuberant Ctags when creating a TAGS files in a directory
1283 without files to scan but with subdirectories to include.
1285 * Bugs introduced by 1.8:
1287 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1288 not defined in the same conditions as the _LDADD that uses it.
1290 - Do not warn when JAVAROOT is overridden, this is legitimate.
1292 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1294 Bugs fixed in 1.8.3:
1296 * Long-standing bugs:
1298 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1299 or any of the other *dir variables contain a space.
1301 Please note that Automake does not and cannot support spaces in
1302 filenames that are involved during the build. This change affects
1303 only installation paths, so that `make install' does not bomb out
1304 in packages configured with
1305 ./configure --prefix '/c/Program Files'
1307 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1308 POSIXLY_CORRECT is set.
1310 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1311 since Autoconf 2.54, which defines LIBOBJS itself.
1313 - Fix a potential (but unlikely) race condition in parallel elisp
1314 builds. (Introduced in 1.7.3.)
1316 - Do not assume that users override _DEPENDENCIES in all conditions
1317 where Automake will try to define them.
1319 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1320 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1323 This fix also affects the $(mkdir_p) variable defined since
1324 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1325 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1327 - Secure temporary directory creation in `make distcheck'. (PR/413)
1329 - Do not generate two build rules for `parser.h' when the
1330 parser appears in two different conditionals.
1332 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1333 checking. Usually ./configure will not pick this shell; so this
1334 fix only helps cases where the shell is forced to /bin/sh.
1336 * Bugs introduced by 1.8:
1338 - In some situations (hand-written `m4_include's), aclocal would
1339 call the `File::Spec->rel2abs' method, which was only introduced
1340 in Perl 5.6. This new version reestablish support Perl 5.005.
1342 It is likely that the next major Automake releases will require at
1343 least Perl 5.6. Consider upgrading your development environment
1344 if you are still using the five-year-old Perl 5.005.
1346 - Automake would sometimes fail to define rules for targets listed
1347 in variables defined in multiple conditions. For instance on
1353 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1354 `b.$(OBJEXT): b.c' rule.
1356 * New sections in manual:
1358 - Third-Party Makefiles: how to interface third party Makefiles.
1359 - Upgrading: upgrading packages to newer Automake versions.
1360 - Multiple Outputs: handling tools that produce many outputs.
1362 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1366 * A (well known) portability bug slipped in the changes made to
1367 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1368 install anything on Tru64.
1370 * Fix install rules for conditionally built python files. (This never
1373 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1377 * Bugs introduced by 1.8:
1379 - Fix Config.pm import error with old Perl versions (at least
1380 5.005_03). One symptom is that aclocal could not find its macro
1383 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1384 created by `make install' are always world readable, even if the
1385 installer happens to have an overly restrictive umask (e.g. 077).
1386 This was a mistake and has been reverted. There are at least two
1387 reasons why we must not use `-m 0755':
1388 - it causes special bits like SGID to be ignored,
1389 - it may be too restrictive (some setups expect 775 directories).
1391 - Fix aclocal to honor definitions located in files which have been
1392 m4_included manually. aclocal 1.8 had been updated to check
1393 m4_included files for new requirements, but forgot that these
1394 m4_included files can also provide new definitions.
1396 Note that if you have such a setup, we recommend you get rid of
1397 it. In the past, there was a reason to m4_include files manually:
1398 aclocal used to duplicate entire M4 files into aclocal.m4, even
1399 files that were distributed. Some packages were therefore
1400 m4_including the distributed file directly, and playing some
1401 tricks to ensure aclocal would not copy that file to aclocal.m4,
1402 in order to limit the amount of duplication. Since aclocal 1.8.x
1403 will precisely output m4_includes for local M4 files, we recommend
1404 that you clean up your setup, removing all manual m4_includes and
1405 letting aclocal output them.
1407 - Output detailed menus in the Info version if the Automake manual,
1408 so that Emacs can locate the indexes.
1410 - configure.ac and configure were listed twice in DIST_COMMON (an
1411 internal variable where Automake lists configury files to
1412 distribute). This was harmless, but unaesthetic.
1414 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1415 This was an issue only in the Automake package itself, not in
1418 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1419 DEST:SRC. This was wrong, as some packages do
1420 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1423 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1424 argument. This caused two kinds of failures:
1425 - Rules installing data in a conditionally defined directory
1426 failed when that directory was undefined. In this case no
1427 argument was supplied.
1428 - `make installdirs' failed, because several directories were
1429 passed to $(mkdir_p). This was an issue only on platform
1430 were $(mkdir_p) is implemented with `install-sh -d'.
1431 $(mkdir_p) as been changed to accept 0 or more arguments, as
1434 * Long-standing bugs:
1436 - Fix an unexpected diagnostic occurring when users attempt
1437 to override some internal variables that Automake appends to.
1439 - aclocal now scans configure.ac for macro definitions (PR/319).
1441 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1442 distributes files which are outside itself (this usually occurs
1443 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1444 from a parent package), then `make distcheck' fails due to an
1445 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1446 (tests/subpkg2.test failure)
1448 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1449 In a VPATH-build configuration, `make install' would install
1450 nobase_ files to wrong locations.
1452 - Fix a Perl `uninitialized value' diagnostic occurring when
1453 automake complains that a Texinfo file does not have a
1454 @setfilename statement.
1456 - Erase config.status.lineno during `make distclean'. This file
1457 can be created by config.status. Automake already knew about
1458 configure.lineno, but forgot config.status.lineno.
1460 - Distribute all files, even those which are built and installed
1461 conditionally. This change affects files listed in conditionally
1462 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1463 as well as those listed in conditionally defined dist_*_DATA,
1464 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1466 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1467 doesn't conform to POSIX.
1469 - Normalize help strings for configure variables and options added
1474 - Check for python2.4 in AM_PATH_PYTHON.
1476 * Spurious failures in test suite:
1478 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1479 tests/ltconv.test: fix failures with CVS Libtool.
1480 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1481 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1482 fix failures with old Texinfo versions.
1484 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1490 - The NEWS file is more verbose.
1494 - Autoconf 2.58 or greater is required.
1498 - Default source file names in the absence of a _SOURCES declaration
1499 are made by removing any target extension before appending `.c', so
1500 to make the libtool module `foo.la' from `foo.c', you only need to
1503 lib_LTLIBRARIES = foo.la
1504 foo_la_LDFLAGS = -module
1506 For backward compatibility, foo_la.c will be used instead of
1507 foo.c if this file exists or is the explicit target of a rule.
1508 However -Wobsolete will warn about this deprecated naming.
1510 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1511 of being hard-coded in each $(AR) invocation, so they can be
1512 substituted from configure.ac. This has been requested by people
1513 dealing with non-POSIX ar implementations.
1515 - New warning option: -Woverride. This will warn about any user
1516 target or variable definitions which override Automake
1519 - Texinfo rules back up and restore info files when makeinfo fails.
1521 - Texinfo rules now support the `html' target.
1522 Running this requires Texinfo 4.0 or greater.
1524 `html' is a new recursive target, so if your package mixes
1525 hand-crafted `Makefile.in's with Automake-generated
1526 `Makefile.in's, you should adjust the former to support (or
1527 ignore) this target so that `make html' recurses successfully. If
1528 you had a custom `html' rule in your `Makefile.am', it's better to
1529 rename it as `html-local', otherwise your rule will override
1530 Automake's new rule (you can check that by running `automake
1531 -Woverride') and that will stop the recursion to subdirectories.
1533 Last but not least, this `html' rule is declared PHONY, even when
1534 overridden. Fortunately, it appears that few packages use a
1535 non-PHONY `html' rule.
1537 - Any file which is m4_included from configure.ac will appear as a
1538 configure and Makefile.in dependency, and will be automatically
1541 - The rules for rebuilding Makefiles and Makefile.ins will now
1542 rebuild all Makefiles and all Makefile.ins at once when one of
1543 configure's dependencies has changed. This is considerably faster
1544 than previous implementations, where config.status and automake
1545 were run separately in each directory (this still happens when you
1546 change a Makefile.am locally, without touching configure.ac or
1547 friends). Doing this also solves a longstanding issue: these
1548 rebuild rules failed to work when adding new directories to the
1549 tree, forcing you to run automake manually.
1551 - For similar reasons, the rules to rebuild configure,
1552 config.status, and aclocal.m4 are now defined in all directories.
1553 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1554 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1555 should better define them in all directories. This is easily done
1556 using an AC_SUBST (make sure you prefix these dependencies with
1557 $(top_srcdir) since this variable will appear at different
1558 levels of the build tree).
1560 - aclocal will now use `m4_include' instead of copying local m4
1561 files into aclocal.m4. (Local m4 files are those you ship with
1562 your project, other files will be copied as usual.)
1564 Because m4_included files are automatically distributed, it means
1565 for most projects there is no point in EXTRA_DISTing the list of
1566 m4 files which are used. (You can probably get rid of
1567 m4/Makefile.am if you had one.)
1569 - aclocal will avoid touching aclocal.m4 when possible, so that
1570 Autom4te's cache isn't needlessly invalidated. This behavior can
1571 be switched off with the new `--force' option.
1573 - aclocal now uses Autoconf's --trace to detect macros which are
1574 actually used and will no longer include unused macros simply
1575 because they where mentioned. This was often the case for macros
1576 called conditionally.
1578 - New options no-dist and no-dist-gzip.
1580 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1581 py-compile, and ylwrap, now all understand --version and --help.
1583 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1584 links as part of the distclean target and including source files in
1587 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1588 argument. The latter can be used to override the default behavior
1589 (which is to abort).
1591 - Automake will exit with $? = 63 on version mismatch. (So does
1592 Autoconf 2.58) missing knows this, and in this case it will
1593 emulate the tools as if they were absent. Because older versions
1594 of Automake and Autoconf did not use this exit code, this change
1595 will only be useful in projects generated with future versions of
1598 - When using AC_CONFIG_FILES with multiple input files, Automake
1599 generates the first ".in" input file for which a ".am" exists.
1600 (Former versions would try to use only the first input file.)
1602 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1603 idiom to disable byte-compilation of lisp_LISP files, it is
1604 recommended that you switch to using lisp_DATA. Note that
1605 this is not strictly equivalent: lisp_DATA will install elisp
1606 files even if emacs is not installed, while *_LISP do not
1607 install anything unless emacs is found.
1609 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1610 available. This selection is achieved through the Makefile
1611 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1612 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1613 `$(install_sh) -m 0755 -d'.
1617 - Because `mkdir -p' is available on most platforms, and we can use
1618 `install-sh -d' when it is not, the use of the mkinstalldirs
1619 script is being phased out. `automake --add-missing' no longer
1620 installs it, and if you remove mkinstalldirs from your package,
1621 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1623 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1624 gettextize and autopoint will install it when needed. Automake
1625 will continue to define the $(mkinstalldirs) and to distribute
1626 mkinstalldirs when this script is in the source tree.
1628 - AM_PROG_CC_STDC is now empty. The content of this macro was
1629 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1630 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1631 renaming should be safe, even if you have to support several,
1632 versions of Automake, because AC_PROG_CC defines this variable
1633 since Autoconf 2.54.)
1635 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1636 variable to override the aclocal.m4 dependencies computed
1637 (inaccurately) by older versions of Automake. Because Automake
1638 now tracks configure's m4 dependencies accurately (see m4_include
1639 above), the use of ACLOCAL_M4_SOURCES should be considered
1640 obsolete and will be flagged as such when running `automake
1645 - Defining programs conditionally using Automake conditionals no
1646 longer leads to a combinatorial explosion. The following
1647 construct used to be troublesome when used with dozens of
1662 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1664 - Due to implementation constraints, previous versions of Automake
1665 proscribed multiple conditional definitions of some variables
1675 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1676 This restriction has been lifted, and these variables now
1677 support multiple conditional definitions as do other variables.
1679 - Cleanup the definitions of $(distdir) and $(top_distdir).
1680 $(top_distdir) now points to the root of the distribution
1681 directory created during `make dist', as it did in Automake 1.4,
1682 not to the root of the build tree as it did in intervening
1683 versions. Furthermore these two variables are now only defined in
1684 the top level Makefile, and passed to sub-directories when running
1687 - The --no-force option now correctly checks the Makefile.in's
1688 dependencies before deciding not to update it.
1690 - Do not assume that make files are called Makefile in cleaning rules.
1692 - Update .info files in the source tree, not in the build tree. This
1693 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1694 used to update these files in the build tree (previous versions did
1695 it in the source tree too), and it caused several problems, varying
1696 from mere annoyance to portability issues.
1698 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1699 when --add-missing and --force-missing are used. For backward
1700 compatibility --add-missing will continue to install COPYING (in
1701 `gnu' strictness) when none of these three files exist, but this
1702 use is deprecated: you should better choose a license yourself and
1703 install it once for all in your source tree (and in your code
1706 - Fix ylwrap so that it does not overwrite header files that haven't
1707 changed, as the inline rule already does.
1709 - User-defined rules override automake-defined rules for the same
1710 targets, even when rules do not have commands. This is not new
1711 (and was documented), however some of the automake-generated
1712 rules have escaped this principle in former Automake versions.
1713 Rules for the following targets are affected by this fix:
1715 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1716 info, info-am, install-data-am, install-exec-am, install-info,
1717 install-info-am, install-man, installcheck-am, maintainer-clean,
1718 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1719 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1721 Practically it means that an attempt to supplement the dependencies
1722 of some target, as in
1724 clean: my-clean-rule
1726 will now *silently override* the automake definition of the
1727 rule for this target. Running `automake -Woverride' will diagnose
1728 all such overriding definitions.
1730 It should be noted that almost all of these targets support a *-local
1731 variant that is meant to supplement the automake-defined rule
1732 (See node `Extending' in the manual). The above rule should
1735 clean-local: my-clean-rule
1737 These *-local targets have been documented since at least
1738 Automake 1.2, so you should not fear the change if you have
1739 to support multiple automake versions.
1743 - The Automake manual is now distributed under the terms of the GNU FDL.
1745 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1747 - core dumps are no longer removed by the cleaning rules. There are
1748 at least three reasons for this:
1749 1. These files should not be created by any build step,
1750 so their removal do not fit any of the cleaning rules.
1751 Actually, they may be precious to the developer.
1752 2. If such file is created during a build, then it's clearly a
1753 bug Automake should not hide. Not removing the file will
1754 cause `make distcheck' to complain about its presence.
1755 3. Operating systems have different naming conventions for
1756 core dump files. A core file on one system might be a
1757 completely legitimate data file on another system.
1759 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1760 defined by Automake. This means that any definition in the
1761 environment will be used, unless overridden in the Makefile.am or
1762 on the command line. The old behavior, where these variables were
1763 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1764 AC_ARG_VARing each variable from configure.ac.
1766 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1767 documented. (The is not a new feature, these variables have
1768 been there since at least Automake 1.4.)
1770 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1772 Bugs fixed in 1.7.9:
1773 * Fix install-strip to work with nobase_ binaries.
1774 * Fix renaming of #line directives in ylwrap.
1775 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1777 Bugs fixed in 1.7.8:
1778 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1779 * Fix detection of Debian's install-info, broken since version 1.5.
1780 (Debian bug #213524).
1781 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1782 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1784 Bugs fixed in 1.7.7:
1785 * The implementation of automake's --no-force option is unreliable,
1786 so this option is ignored in this version. A real fix will appear in
1787 Automake 1.8. (Debian Bug #206299)
1788 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1789 argument is given. (PR/399)
1790 * Do not warn about leading `_' in variable names, even with -Wportability.
1791 * Support user redefinitions of TEXINFO_TEX.
1792 * depcomp: support AIX Compiler version 6.
1793 * Fix missing rebuilds during `make dist' with BSD make.

1813 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1814 that caused invalid Makefile.ins to be generated.

1832 * Minor documentation fixes.
1834 Bugs fixed in 1.7.3:
1835 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1836 * Query distutils for `pythondir' and `pythonexecdir', instead of
1837 using an hardcoded path. This should allow builds on 64-bit
1838 distributions that usually use lib64/ instead of lib/.
1839 * AM_PATH_PYTHON will also search for python2.3.
1840 * elisp files are now built all at once instead of one by one. Besides
1841 incurring a speed-up, this is required to support interdependent elisp files.
1842 * Support for DJGPP:
1843 - `make distcheck' will now work in `_inst/' and `_build' instead
1844 of `=inst/' and `=build/'
1845 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1846 - install/uninstall `*.i[0-9][0-9]'-style info files

1849 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1850 PACKAGE and VERSION.
1852 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1853 is troublesome with gcc and Solaris compilers. (PR/385)

1877 * Honor only the first @setfilename seen in a Texinfo file.
1878 * Treat "required file X not found" diagnostics as errors (exit status 1).

1926 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1927 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1928 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1929 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1930 `configure.ac' for you.
1931 * Support for per-program and per-library `_CPPFLAGS'.
1932 * New `ctags' target (builds CTAGS files).

1935 * Honor the WARNINGS environment variable.
1936 * Omit the call to depcomp when using gcc3: call the compiler directly.

1940 * Info files are now created in the build directory, not the source directory.
1941 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1

1945 * `+=' can be used in conditionals, even if the augmented variable
1946 was defined for another condition.
1947 * Makefile fragments (inserted with `include') are always distributed.
1948 * Use Autoconf's --trace interface to inspect configure.ac and get
1949 a more accurate view of it.
1950 * Add support for extending aclocal's default macro search path
1951 using a `dirlist' file within the aclocal directory.
1952 * automake --output-dir is deprecated.
1953 * The part of the distcheck target that checks whether uninstall actually
1954 removes all installed files has been moved in a separate target,
1955 distuninstallcheck, so it can be overridden easily.
1959 * Support for AM_INIT_GETTEXT([external])
1960 * Bug fixes, including:
1961 - Fix Automake's own `make install' so it works even if `ln' doesn't.

1979 - Don't choke on AM_LDFLAGS definitions.
1980 - Clean libtool objects from subdirectories.
1981 - Allow configure variables with reserved suffix and unknown prefix
1982 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1983 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1986 * Autoconf 2.52 is required.
1987 * automake no longer run libtoolize.
1988 This is the job of autoreconf (from GNU Autoconf).
1989 * `dist' generates all the archive flavors, as did `dist-all'.
1990 * `dist-gzip' generates the Gzip tar file only.
1991 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1992 explosion. Makefile.in's keep a reasonable size.
1993 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1994 are no longer shipped, since Autoconf 2.52 provides them (both as AM_

1997 * EXTRA_DIST can contain generated directories.
1998 * Support for dot-less extensions in suffix rules.
1999 * The part of the distcheck target that checks whether distclean actually

2010 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
2011 (Note that "pkgname" is not "tarname", see the manual for details.)
2012 It is also possible to pass a list of global Automake options as
2013 first argument to this new form of AM_INIT_AUTOMAKE.
2014 * Compiler-based assembler is now called `CCAS'; people expected `AS'
2015 to be a real assembler.
2016 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
2017 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
