3 * Version requirements:
5 - Autoconf 2.65 or greater is required.
7 - The rules to build PDF and DVI output from Texinfo input now
8 requires Texinfo 4.9 or later.
10 * Obsolete features removed:
12 - Use of the long-deprecated two- and three-arguments invocation forms
13 of the AM_INIT_AUTOMAKE is not supported anymore.
15 - Support for the "Cygnus-style" trees (once enabled by the 'cygnus'
16 option) has been removed. See discussion about automake bug#11034
19 - The automake-provided '@mkdir_p@' configure substitution and
20 AM_PROG_MKDIR m4 macro have been removed. They had been obsolete
21 since automake 1.10, and actively deprecated since Automake 1.12.1.
22 However, to maintain a degree of backward-compatibility, the make
23 variable '$(mkdir_p)' is still defined (now simple as an alias to
24 '$(MKDIR_P)'). It will probably be removed in future major versions
25 of Automake (probably 1.14).
27 - The deprecated aclocal option '--acdir' has been removed. You
28 should use the options '--automake-acdir' and '--system-acdir'
29 instead (which have been introduced in Automake 1.11.2).
31 - The following long-obsolete m4 macros have been removed:
33 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
34 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
35 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
36 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
37 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
38 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
39 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
40 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
41 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
42 of the now-removed automatic de-ANSI-fication
45 - All the "old alias" macros in 'm4/obsolete.m4' have been removed.
47 * Changes to Automake-generated testsuite harnesses:
49 - The parallel testsuite harness (previously only enabled by the
50 'parallel-tests' option) is the default one; the older serial
51 testsuite harness will still be available through the use of the
52 'serial-tests' option (introduced in Automake 1.12).
54 * Silent rules support:
56 - Support for silent rules is now always active in Automake-generated
57 Makefiles. So, although the verbose output is still the default,
58 the user can now always use "./configure --enable-silent-rules" or
59 "make V=0" to enable quieter output in the package he's building.
61 - The 'silent-rules' option has now become a no-op, preserved for
62 backward-compatibility only. In particular, its use does not disable
63 the warnings in the 'portability-recursive' category anymore.
67 - The rules to build PDF and DVI files from Texinfo input now use the
68 ' --build-dir' option, to keep the auxiliary files used by texi2dvi
69 and texi2pdf around without cluttering the build directory, and to
70 make it possible to run the "dvi" and "pdf" recipes in parallel.
72 * Automatic remake rules and 'missing' script:
74 - The 'missing' script does not try anymore to update the timestamp
75 of out-of-date files that require a maintainer-specific tool to be
76 remade, in case the user lacks such a tool (or has a too-old version
77 of it). It just give a useful warning, and in some cases also a tip
78 about how to obtain such a tool.
80 - The missing script has thus become useless as a (poor) way to work
81 around the sketched-timestamps issues that can happen for projects
82 that keep generated files committed in their VCS repository. Such
83 projects are now encouraged to write a custom "fix-timestamps.sh"
84 script to avoid such issues; a simple example is provided in the
85 "CVS and generated files" chapter of the automake manual.
89 The user can now define his own recursive targets that recurse
90 in the directories specified in $(SUBDIRS). This can be done by
91 specifying the name of such targets in invocations of the new
92 'AM_EXTRA_RECURSIVE_TARGETS' m4 macro.
94 * Improvements to aclocal and related rebuilds rules:
96 - The Autoconf-provided macro AC_CONFIG_MACRO_DIR is now traced by
97 aclocal, and can be used to declare the local m4 include directory.
98 Formerly, one had to specify it with an explicit '-I' option to the
101 - The special make variable ACLOCAL_AMFLAGS is deprecated; future
102 Automake versions will warn about its use, and later version will
103 remove support for it altogether.
105 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
109 * WARNING: Future backward-incompatibilities!
111 - Future versions of Automake will likely drop support for the
112 long-deprecated 'configure.in' name for the Autoconf input file.
113 You are advised to use the recommended name 'configure.ac' instead.
115 - Starting from the next major Automake version (1.13), the rules to
116 build pdf, ps and dvi output from Texinfo input will use the '--tidy'
117 option by default. Since such an option was introduced in Texinfo
118 4.9, this means that Makefiles generated by future Automake versions
119 will require at least that version of Texinfo.
121 - Starting from the next major Automake version (1.13), the parallel
122 testsuite harness (previously only enabled by the 'parallel-tests'
123 option) will become the default one; the older serial testsuite
124 harness will still be available through the use of the 'serial-tests'
127 - Support for the two- and three-arguments invocation forms of the
128 AM_INIT_AUTOMAKE macro is deprecated, and will be removed in the
129 next major Automake version (1.13).
131 - The exact order in which the directories in the aclocal macro
132 search path are looked up is probably going to be changed in the
133 next Automake release (1.13).
135 - The 'missing' script will not try anymore to update the timestamp
136 of out-of-date files that require a maintainer-specific tool to be
137 remade, in case the user lacks such a tool (or has a too-old version
138 of it). In fact, starting from Automake 1.13, all it'll do will be
139 giving more useful warnings than a bare "command not found" from a
142 * Warnings and deprecations:
144 - Automake now issues a warning (in the 'portability' category) if
145 'configure.in' is used instead of 'configure.ac' as the Autoconf
146 input file. Such a warning will also be present in the next
147 Autoconf version (2.70).
151 - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
152 order (as done by the other recursive rules), rather than in the
153 inverse order. They used to do that in order to work a round a
154 limitation in an older implementation of the automatic dependency
155 tracking support, but that limitation had been lifted years ago
156 already, when the automatic dependency tracking based on side-effects
157 of compilation had been introduced.
159 - Cleaning rules for compiled objects (both "plain" and libtool) work
160 better when subdir objects are involved, not triggering a distinct
161 'rm' invocation for each such object. They do so by removing *any*
162 compiled object file that is in the same directory of a subdir
163 object. See automake bug#10697.
165 * Silent rules support:
167 - A new predefined $(AM_V_P) make variable is provided; it expands
168 to a shell conditional that can be used in recipes to know whether
169 make is being run in silent or verbose mode.
171 Bugs fixed in 1.12.2:
173 * SECURITY VULNERABILITIES!
175 - The 'distcheck' recipe no longer grants temporary world-write
176 permissions on the extracted distdir. Even if such rights were
177 only granted for a vanishingly small time window, the implied
178 race condition proved to be enough to allow a local attacker
179 to run arbitrary code with the privileges of the user running
180 "make distcheck". This is CVE-2012-3386.
182 * Long-standing bugs:
184 - The "recheck" targets behaves better in the face of build failures
185 related to previously failed tests. For example, if a test is a
186 compiled program that must be rerun by "make recheck", and its
187 compilation fails, it will still be rerun by further "make recheck"
188 invocations. See automake bug#11791.
190 * Bugs introduced by 1.12.1:
192 - Automake provides once again the '$(mkdir_p)' make variable and the
193 '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
194 for better backward-compatibility.
196 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
200 * New supported languages:
202 - Support for Objective C++ has been added; it should work similarly to
203 the support for Objective C.
205 * Deprecated obsolescent features:
207 - Use of the long-deprecated two- and three-arguments invocation forms
208 of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
209 category. Starting from the next major Automake release (1.13), such
210 usages won't be allowed anymore.
212 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
213 now deprecated (its use triggers a warning in the 'obsolete' category).
214 It will be removed in the next major Automake release (1.13).
216 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
217 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
218 m4 macro are deprecated, eliciting a warning in the 'obsolete'
221 * Miscellaneous changes:
223 - The Automake test cases now require a proper POSIX-conforming shell.
224 Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) won't be
225 accepted anymore. In most cases, the user shouldn't have to specify
226 such POSIX shell explicitly, since it will be looked up at configure
227 time. Still, when this lookup fails, or when the user wants to
228 override its conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be
229 used (pointing to the shell that will be used to run the Automake
232 Bugs fixed in 1.12.1:
234 * Bugs introduced by 1.12:
236 - Several weaknesses in Automake's own build system and test suite
239 * Bugs introduced by 1.11.3:
241 - When given non-option arguments, aclocal rejects them, instead of
242 silently ignoring them.
244 * Long-standing bugs:
246 - When the 'color-tests' option is in use, forcing of colored testsuite
247 output through "AM_COLOR_TESTS=always" works even if the terminal is
248 a non-ANSI one, i.e., if the TERM environment variable has a value of
251 - Several inefficiencies and poor performances in the implementation
252 of the parallel-tests 'check' and 'recheck' targets have been fixed.
254 - The post-processing of output "#line" directives done the ylwrap
255 script is more faithful w.r.t. files in a subdirectory; for example,
256 if the processed file is "src/grammar.y", ylwrap will correctly
257 produce directives like:
258 #line 7 "src/grammar.y"
263 * Bugs with new Perl versions:
265 - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
267 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
271 * Obsolete features removed:
273 - The never documented nor truly used script 'acinstall' has been
276 - Support for automatic de-ANSI-fication has been removed.
278 - The support for the "obscure" multilib feature has been removed
279 from Automake core (but remains available in the 'contrib/'
280 directory of the Automake distribution).
282 - Support for ".log -> .html" conversion and the check-html and
283 recheck-html targets has been removed from Automake core (but
284 remains available in the 'contrib/' directory of the Automake
287 - The deprecated 'lzma' compression format for distribution archives
288 has been removed, in favor of 'xz' and 'lzip'.
290 - The obsolete AM_WITH_REGEX macro has been removed.
292 - The long-deprecated options '--output-dir', '--Werror' and
293 '--Wno-error' have been removed.
295 - The chapter on the history of Automake has been moved out of the
296 reference manual, into a new dedicated Texinfo file.
300 - New 'cscope' target to build a cscope database for the source tree.
302 * Changes to Automake-generated testsuite harnesses:
304 - The new automake option 'serial-tests' has been introduced. It can
305 be used to explicitly instruct automake to use the older serial
306 testsuite harness. This is still the default at the moment, but it
307 might change in future versions.
309 - The 'recheck' target (provided by the parallel testsuite harness) now
310 depends on the 'all' target. This allows for a better user-experience
311 in test-driven development. See automake bug#11252.
313 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
314 and unexpected or internal error, or a failure to set up the test case
315 scenario) have their outcome reported as an 'ERROR' now. Previous
316 versions of automake reported such an outcome as a 'FAIL' (the only
317 difference with normal failures being that hard errors were counted
318 as failures even when the test originating them was listed in
321 - The testsuite summary displayed by the parallel-test harness has a
322 completely new format, that always list the numbers of passed, failed,
323 xfailed, xpassed, skipped and errored tests, even when these numbers
324 are zero (but using smart coloring when the color-tests option is in
327 - The default testsuite driver offered by the 'parallel-tests' option is
328 now implemented (partly at least) with the help of automake-provided
329 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
330 on code in the generated Makefile.in.
331 This has two noteworthy implications. The first one is that projects
332 using the 'parallel-tests' option should now either run automake with
333 the '--add-missing' option, or manually copy the 'test-driver' script
334 into their tree. The second, and more important, implication is that
335 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
336 not be used anymore to define a test runner, and the command specified
337 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
338 program or script. For example, this is still a valid usage (albeit
341 TESTS_ENVIRONMENT = \
342 if test -n '$(STRICT_TESTS)'; then \
343 maybe_errexit='-e'; \
347 LOG_COMPILER = $(SHELL) $$maybe_errexit
349 while this is not anymore:
351 TESTS_ENVIRONMENT = \
352 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
356 TESTS_ENVIRONMENT = \
357 run_with_perl_or_shell () \
359 if grep -q '^#!.*perl' $$1; then
365 LOG_COMPILER = run_with_perl_or_shell
367 - The package authors can now use customary testsuite drivers within
368 the framework provided by the 'parallel-tests' testsuite harness.
369 Consistently with the existing syntax, this can be done by defining
370 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
372 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
373 to redirect/define file descriptors used by the test scripts.
375 - The parallel-tests harness generates now, in addition the '.log' files
376 holding the output produced by the test scripts, a new set of '.trs'
377 files, holding "metadata" derived by the execution of the test scripts;
378 among such metadata are the outcomes of the test cases run by a script.
380 - Initial and still experimental support for the TAP test protocol is
383 * Changes to Yacc and Lex support:
385 - C source and header files derived from non-distributed Yacc and/or
386 Lex sources are now removed by a simple "make clean" (while they were
387 previously removed only by "make maintainer-clean").
389 - Slightly backward-incompatible change, relevant only for use of Yacc
390 with C++: the extensions of the header files produced by the Yacc
391 rules are now modelled after the extension of the corresponding
392 sources. For example, yacc files named "foo.y++" and "bar.yy" will
393 produce header files named "foo.h++" and "bar.hh" respectively, where
394 they would have previously produced header files named simply "foo.h"
395 and "bar.h". This change offers better compatibility with 'bison -o'.
397 * Miscellaneous changes:
399 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
400 rather than 1, if the vala compiler found is too old.
402 - The build system of Automake itself now avoids the use of make
403 recursion as much as possible.
405 - Automake now prefers to quote 'like this' or "like this", rather
406 than `like this', in diagnostic message and generated Makefiles,
407 to accommodate the new GNU Coding Standards recommendations.
409 - Automake has a new option '--print-libdir' that prints the path of the
410 directory containing the Automake-provided scripts and data files.
412 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
414 - The rules to create pdf, dvi and ps output from Texinfo files now
415 works better with modern 'texi2dvi' script, by explicitly passing
416 it the '--clean' option to ensure stray auxiliary files are not
417 left to clutter the build directory.
419 - Automake can now generate silenced rules for texinfo outputs.
421 - Some auxiliary files that are automatically distributed by Automake
422 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
423 C sources) might now be listed in the DIST_COMMON variable in many
424 Makefile.in files, rather than in the top-level one.
426 - Messages of types warning or error from 'automake' and 'aclocal'
427 are now prefixed with the respective type, and presence of -Werror
430 - Automake's early configure-time sanity check now tries to avoid
431 sleeping for a second, which slowed down cached configure runs
432 noticeably. In that case, it will check back at the end of the
433 configure script to ensure that at least one second has passed, to
434 avoid time stamp issues with makefile rules rerunning autotools
437 - The warnings in the category 'extra-portability' are now enabled by
438 '-Wall'. In previous versions, one has to use '-Wextra-portability'
443 - Various minor bugfixes for recent or long-standing bugs.
445 * Bugs introduced by 1.11:
447 - The AM_COND_IF macro also works if the shell expression for the
448 conditional is no longer valid for the condition.
450 - The automake-provided parallel testsuite harness does not fail anymore
451 with BSD make used in parallel mode when there are test scripts in a
452 subdirectory, like in:
454 TESTS = sub/foo.test sub/bar.test
456 * Long-standing bugs:
458 - Automake's own build system finally have a real "installcheck" target.
460 - Vala-related cleanup rules are now more complete, and work better in
463 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
464 now automatically distributed also if the directory of the auxiliary
465 files coincides with the top-level directory.
467 - Automake now detects the presence of the '-d' flag in the various
468 '*YFLAGS' variables even when their definitions involve indirections
469 through other variables, such as in:
471 AM_YFLAGS = $(foo_opts)
473 - Automake now complains if a '*YFLAGS' variable has any conditional
474 content, not only a conditional definition.
476 - Explicit enabling and/or disabling of Automake warning categories
477 through the '-W...' options now always takes precedence over the
478 implicit warning level implied by Automake strictness (foreign, gnu
479 or gnits), regardless of the order in which such strictness and
480 warning flags appear. For example, a setting like:
481 AUTOMAKE_OPTIONS = -Wall --foreign
482 will cause the warnings in category 'portability' to be enabled, even
483 if those warnings are by default disabled in 'foreign' strictness.
485 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
487 Bugs fixed in 1.11.5:
489 * Bugs introduced by 1.11.3:
491 - Vala files with '.vapi' extension are now recognized and handled
492 correctly again. See automake bug#11222.
494 - Vala support work again for projects that contain some program
495 built from '.vala' (and possibly '.c') sources and some other
496 program built from '.c' sources *only*. See automake bug#11229.
498 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
502 * Miscellaneous changes:
504 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
505 symbol index) modifiers as well as the "s" action, as the symbol index
506 is created unconditionally by Microsoft lib. Also, the "q" (quick)
507 action is now a synonym for "r" (replace). Also, the script has been
508 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
510 - When the 'compile' script is used to wrap MSVC, it now accepts an
511 optional space between the -I, -L and -l options and their respective
512 arguments, for better POSIX compliance.
514 - There is an initial, experimental support for automatic dependency
515 tracking with tcc (the Tiny C Compiler). Its associated depmode is
516 currently recognized as "icc" (but this and other details are likely
517 to change in future versions).
519 - Automatic dependency tracking now works also with the IBM XL C/C++
520 compilers, thanks to the new new depmode 'xlc'.
522 Bugs fixed in 1.11.4:
524 * Bugs introduced by 1.11.2:
526 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
527 don't cause spurious failures upon "make install" anymore.
529 - The user can now instruct the 'uninstall-info' rule not to update
530 the '${infodir}/dir' file by exporting the environment variable
531 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
532 with how the 'install-info' rule operates since automake 1.11.2.
534 * Long-standing bugs:
536 - It is now possible for a foo_SOURCES variable to hold Vala sources
537 together with C header files, as well as with sources and headers for
538 other supported languages (e.g., C++). Previously, only mixing C and
539 Vala sources was supported.
541 - If "aclocal --install" is used, and the first directory specified with
542 '-I' is non-existent, aclocal will now create it before trying to copy
545 - An empty declaration of a "foo_PRIMARY" don't cause anymore the
546 generated install rules to create an empty $(foodir) directory;
547 for example, if Makefile.am contains something like:
551 pkglibexec_SCRIPTS += bar.sh
554 the $(pkglibexec) directory will not be created upon "make install".
556 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
560 * Miscellaneous changes:
562 - Automake's own build system is more silent by default, making use of
563 the 'silent-rules' option.
565 - The master copy of the `gnupload' script is now maintained in gnulib,
568 - The `missing' script doesn't try to wrap calls to `tar' anymore.
570 - "make dist" doesn't wrap `tar' invocations with the `missing' script
571 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
572 shouldn't be using BTW ;-) does not invoke the missing script anymore
573 to wrap tar, but simply invokes the `tar' program itself.
575 - "make dist" can now create lzip-compressed tarballs.
577 - In the Automake info documentation, the Top node and the nodes about
578 the invocation of the automake and aclocal programs have been renamed;
579 now, calling "info automake" will open the Top node, while calling
580 "info automake-invocation" and "info aclocal-invocation" will access
581 the nodes about the invocation of respectively automake and aclocal.
583 - Automake is now distributed as a gzip-compressed and an xz-compressed
584 tarball. Previously, bzip2 was used instead of xz.
586 - The last relics of Python 1.5 support have been removed from the
587 AM_PATH_PYTHON macro.
589 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
590 and adds them to the normal list of dependencies, but without
591 overwriting the foo_DEPENDENCIES variable, which is normally computed
594 Bugs fixed in 1.11.3:
596 * Bugs introduced by 1.11.2:
598 - Automake now correctly recognizes the prefix/primary combination
599 `pkglibexec_SCRIPTS' as valid.
601 - The parallel-tests harness doesn't trip anymore on sed implementations
602 with stricter limits on the length of input lines (problem seen at
605 * Long-standing bugs:
607 - The "deleted header file problem" for *.am files is avoided by stub
608 rules. This allows `make' to trigger a rerun of `automake' also if
609 some previously needed `.am' file has been removed.
611 - The `silent-rules' option now generates working makefiles even
612 for the uncommon `make' implementations that do not support the
613 nested-variables extension to POSIX 2008. For such `make'
614 implementations, whether a build is silent is determined at
615 configure time, and cannot be overridden at make time with
616 `make V=0' or `make V=1'.
618 - Vala support now works better in VPATH setups.
620 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
624 * Changes to aclocal:
626 - The `--acdir' option is deprecated. Now you should use the new options
627 `--automake-acdir' and `--system-acdir' instead.
629 - The `ACLOCAL_PATH' environment variable is now interpreted as a
630 colon-separated list of additional directories to search after the
631 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
632 and before the system acdir (by default ${prefix}/share/aclocal).
634 * Miscellaneous changes:
636 - The Automake support for automatic de-ANSI-fication has been
637 deprecated. It will probably be removed in the next major Automake
640 - The `lzma' compression scheme and associated automake option `dist-lzma'
641 is obsoleted by `xz' and `dist-xz' due to upstream changes.
643 - You may adjust the compression options used in dist-xz and dist-bzip2.
644 The default is now merely -e for xz, but still -9 for bzip; you may
645 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
646 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
648 - The `compile' script now converts some options for MSVC for a better
649 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
651 - The py-compile script now accepts empty arguments passed to the options
652 `--destdir' and `--basedir', and complains about unrecognized options.
653 Moreover, a non-option argument or a special `--' argument terminates
656 - A developer that needs to pass specific flags to configure at "make
657 distcheck" time can now, and indeed is advised to, do so by defining
658 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
659 instead of the old DISTCHECK_CONFIGURE_FLAGS.
660 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
661 user; still, the old Makefile.am files that used to define it will
662 still continue to work as before.
664 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
665 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
666 This new macro is required for LIBRARIES and LTLIBRARIES when automake
667 is run with -Wextra-portability and -Werror.
669 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
670 file generated by automake-provided rules by defining the special make
671 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
673 - The `install-info' rule can now be instructed not to create/update
674 the `${infodir}/dir' file, by exporting the new environment variable
675 `AM_UPDATE_INFO_DIR' to the value "no".
677 Bugs fixed in 1.11.2:
679 * Bugs introduced by 1.11:
681 - The parallel-tests driver no longer produces erroneous results with
682 Tru64/OSF 5.1 sh upon unreadable log files.
684 - The `parallel-tests' test driver does not report spurious successes
685 when used with concurrent FreeBSD make (e.g., "make check -j3").
687 - When the parallel-tests driver is in use, automake now explicitly
688 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
689 instead of issuing confusing and apparently unrelated error messages
690 (e.g., "non-POSIX variable name", "bad characters in variable name",
691 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
692 silently producing broken `Makefile.in' files.
694 - The `silent-rules' option now truly silences all compile rules, even
695 when dependency tracking is disabled. Also, when `silent-rules' is
696 not used, `make' output no longer contains spurious backslash-only
697 lines, thus once again matching what Automake did before 1.11.
699 - The AM_COND_IF macro also works if the shell expression for the
700 conditional is no longer valid for the condition.
702 * Long-standing bugs:
704 - The order of Yacc and Lex flags is fixed to be consistent with other
705 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
706 $(LFLAGS), so that the user variables override the developer variables.
708 - "make distcheck" now correctly complains also when "make uninstall"
709 leaves one and only one file installed in $(prefix).
711 - A "make uninstall" issued before a "make install", or after a mere
712 "make install-data" or a mere "make install-exec" does not spuriously
715 - Automake now warns about more primary/directory invalid combinations,
716 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
718 - Rules generated by Automake now try harder to not change any files when
719 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
720 Yacc source files and the rule to update config.h.
722 - Several scripts and the parallel-tests testsuite driver now exit with
723 the right exit status upon receiving a signal.
725 - A per-Makefile.am setting of -Werror does not erroneously carry over
726 to the handling of other Makefile.am files.
728 - The code for automatic dependency tracking works around a Solaris
729 make bug triggered by sources containing repeated slashes when the
730 `subdir-objects' option was used.
732 - The makedepend and hp depmodes now work better with VPATH builds.
734 - Java sources specified with check_JAVA are no longer compiled for
735 "make all", but only for "make check".
737 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
738 and error out if `javadir' is undefined, instead of silently producing
739 a broken Makefile.in.
741 - aclocal and automake now honour the configure-time definitions of
742 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
744 - The `install-info' recipe no longer tries to guess whether the
745 `install-info' program is from Debian or from GNU, and adaptively
746 change its behaviour; this has proven to be frail and easy to
749 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
751 Bugs fixed in 1.11.1:
753 - Lots of minor bugfixes.
755 * Bugs introduced by 1.11:
757 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
758 trailing white space in the test list (`TESTS = foo $(EMPTY)').
760 * Long standing bugs:
762 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
763 even if the `--prefix' argument pointed outside of a system directory.
764 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
765 `get_python_lib' function if it points outside the configured prefix,
766 unless the `--prefix' argument was either `/usr' or below `/System'.
768 - The testsuite does not try to change the mode of `ltmain.sh' files from
769 a Libtool installation (symlinked to test directories) any more.
771 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
772 tools are preferred in a cross-compile setup.
774 - The distribution is tarred up with mode 755 now by the `dist*' targets.
775 This fixes a race condition where untrusted users could modify files
776 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
777 build directory was world-searchable. This is CVE-2009-4029.
779 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
783 * Version requirements:
785 - Autoconf 2.62 or greater is required.
787 * Changes to aclocal:
789 - The autoconf version check implemented by aclocal in aclocal.m4
790 (and new in Automake 1.10) is degraded to a warning. This helps
791 in the common case where the Autoconf versions used are compatible.
793 * Changes to automake:
795 - The automake program can run multiple threads for creating most
796 Makefile.in files concurrently, if at least Perl 5.7.2 is available
797 with interpreter-based threads enabled. Set the environment variable
798 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
799 enable this experimental feature.
801 * Changes to Libtool support:
803 - Libtool generic flags are now passed to the install and uninstall
806 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
807 config.lt is removed correctly now.
811 - subdir-object mode works now with Fortran (F77, FC, preprocessed
812 Fortran, and Ratfor).
814 - For files with extension .f90, .f95, .f03, or .f08, the flag
815 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
817 - Files with extension .sx are also treated as preprocessed assembler.
819 - The default source file extension (.c) can be overridden with
820 AM_DEFAULT_SOURCE_EXT now.
822 - Python 3.0 is supported now, Python releases prior to 2.0 are no
825 - AM_PATH_PYTHON honors python's idea about the site directory.
827 - There is initial support for the Vala programming language, when using
830 * Miscellaneous changes:
832 - Automake development is done in a git repository on Savannah now, see
834 http://git.sv.gnu.org/gitweb/?p=automake.git
836 A read-only CVS mirror is provided at
838 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
839 checkout -d automake HEAD
841 - "make dist" can now create xz-compressed tarballs,
842 as well as (deprecated?) lzma-compressed tarballs.
844 - `automake --add-missing' will by default install the GPLv3 file as
845 COPYING if it is missing. It will also warn that the license file
846 should be added to source control. Note that Automake will never
847 overwrite an existing COPYING file, even when the `--force-missing'
850 - The manual is now distributed under the terms of the GNU FDL 1.3.
852 - Automake ships and installs man pages for automake and aclocal now.
854 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
856 - install-sh supports -C, which does not update the installed file
857 (and its time stamps) if the contents did not change.
859 - The `gnupload' script has been revamped.
861 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
863 - The targets `install' and `uninstall' are more efficient now, in that
864 for example multiple files from one Automake variable such as
865 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
866 invocation if they do not have to be renamed.
868 Both install and uninstall may sometimes enter (`cd' into) the target
869 installation directory now, when no build-local scripts are used.
871 Both install and uninstall do not fail anymore but do nothing if an
872 installation directory variable like `bindir' is set to the empty string.
874 For built-in rules, `make install' now fails reliably if installation
875 of a file failed. Conversely, `make uninstall' even succeeds when
876 issued multiple times.
878 These changes may need some adjustments from users: For example,
879 some `install' programs refuse to install multiple copies of the
880 same file in one invocation, so you may need to remove duplicate
881 entries from file lists.
883 Also, within one set of files, say, nobase_data_DATA, the order of
884 installation may be changed, or even unstable among different hosts,
885 due to the use of associative arrays in awk. The increased use of
886 awk matches a similar move in Autoconf to provide for better scaling.
888 Further, most undocumented per-rule install command variables such as
889 binSCRIPT_INSTALL have been removed because they are not needed any
890 more. Packages which use them should be using the appropriate one of
891 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
892 counterpart, depending on the type of files and the need for automatic
893 target directory creation.
895 - The "deleted header file problem" for *.m4 files is avoided by
896 stub rules. This allows `make' to trigger a rerun of `aclocal'
897 also if some previously needed macro file has been removed.
899 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
900 an otherwise up to date tree.
902 - The `color-tests' option causes colored test result output on terminals.
904 - The `parallel-tests' option enables a new test driver that allows for
905 parallel test execution, inter-test dependencies, lazy test execution
906 for unit-testing, re-testing only failed tests, and formatted result output
907 as RST (reStructuredText) and HTML. Enabling this option may require some
908 changes to your test suite setup; see the manual for details.
910 - The `silent-rules' option enables Linux kernel-style silent build output.
911 This option requires the widely supported but non-POSIX `make' feature
912 of recursive variable expansion, so do not use it if your package needs
913 to build with `make' implementations that do not support it.
915 To enable less verbose build output, the developer has to use the Automake
916 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
917 macro. The user may then set the default verbosity by passing the
918 `--enable-silent-rules' option to `configure'. At `make' run time, this
919 default may be overridden using `make V=0' for less verbose, and `make V=1'
920 for backward-compatible verbose output.
922 - New prefix `notrans_' for manpages which should not be transformed
923 by --program-transform.
925 - New macro AM_COND_IF for conditional evaluation and conditional
928 - For AC_CONFIG_LINKS, if source and destination are equal, do not
929 remove the file in a non-VPATH build. Such setups work with Autoconf
932 - AM_MAINTAINER_MODE now allows for an optional argument specifying
935 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
936 useful especially for multi-line values.
938 - Automake's early configure-time sanity check now diagnoses an
939 unsafe absolute source directory name and makes configure fail.
941 - The Automake macros and rules cope better with whitespace in the
942 current directory name, as long as the relative path to `configure'
943 does not contain whitespace. To this end, the values of `$(MISSING)'
944 and `$(install_sh)' may contain suitable quoting, and their expansion
945 might need `eval'uation if used outside of a makefile. These
946 undocumented variables may be used in several documented macros such
947 as $(AUTOCONF) or $(MAKEINFO).
951 * Long-standing bugs:
953 - Fix aix dependency tracking for libtool objects.
955 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
956 unnecessary use of the `compile' script.
958 - For nobase_*_LTLIBRARIES with nonempty directory components, the
959 correct `-rpath' argument is used now.
961 - `config.status --file=Makefile depfiles' now also works with the
962 extra quoting used internally by Autoconf 2.62 and newer
963 (it used to work only without the `--file=' bit).
965 - The `missing' script works better with versioned tool names.
967 - Semantics for `missing help2man' have been revamped:
969 Previously, if `help2man' was not present, `missing help2man' would have
970 the following semantics: if some man page was out of date but present, then
971 a warning would be printed, but the exit status was 0. If the man page was
972 not present at all, then `missing' would create a replacement man page
973 containing an error message, and exit with a status of 2. This does not play
974 well with `make': the next run will see this particular man page as being up
975 to date, and will only error out on the next generated man page, if any;
976 repeat until all pages are done. This was not desirable.
978 These are the new semantics: if some man page is not present, and help2man
979 is not either, then `missing' will warn and generate the replacement page
980 containing the error message, but exit successfully. However, `make dist'
981 will ensure that no such bogus man pages are packaged into a tarball.
983 - Targets provided by automake behave better with `make -n', in that they
984 take care not to create files.
986 - `config.status Makefile... depfiles' works fine again in the presence of
987 disabled dependency tracking.
989 - The default no-op recursive rules for these targets also work with BSD make
990 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
992 - `make distcheck' works also when both a directory and some file below it
993 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
995 - Texinfo dvi, ps, pdf, and html output files are not removed upon
996 `make mostlyclean' any more; only the LaTeX by-products are.
998 - Renamed objects also work with the `subdir-objects' option and
999 source file languages which Automake does not know itself.
1001 - `automake' now correctly complains about variable assignments which are
1002 preceded by a comment, extend over multiple lines with backslash-escaped
1003 newlines, and end in a comment sign. Previous versions would silently
1004 and wrongly ignore such assignments completely.
1006 * Bugs introduced by 1.10:
1008 - Fix output of dummy dependency files in presence of post-processed
1009 Makefile.in's again, but also cope with long lines.
1011 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
1012 that have been declared as programs in the same Makefile.
1013 This is for consistency with the analogous change to TESTS in 1.10.
1015 - Fix order of standard includes to again be `-I. -I$(srcdir)',
1016 followed by directories containing config headers.
1018 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1022 * Version requirements:
1024 - Autoconf 2.60 or greater is required.
1026 - Perl 5.6 or greater is required.
1028 * Changes to aclocal:
1030 - aclocal now also supports -Wmumble and -Wno-mumble options.
1032 - `dirlist' entries (for the aclocal search path) may use shell
1033 wildcards such as `*', `?', or `[...]'.
1035 - aclocal supports an --install option that will cause system-wide
1036 third-party macros to be installed in the local directory
1037 specified with the first -I flag. This option also uses #serial
1038 lines in M4 files to upgrade local macros.
1040 The new aclocal options --dry-run and --diff help to review changes
1041 before they are installed.
1043 - aclocal now outputs an autoconf version check in aclocal.m4 in
1044 projects using automake.
1046 For a few years, automake and aclocal have been calling autoconf
1047 (or its underlying engine autom4te) to accurately retrieve the
1048 data they need from configure.ac and its siblings. Doing so can
1049 only work if all autotools use the same version of autoconf. For
1050 instance a Makefile.in generated by automake for one version of
1051 autoconf may stop working if configure is regenerated with another
1052 version of autoconf, and vice versa.
1054 This new version check ensures that the whole build system has
1055 been generated using the same autoconf version.
1057 * Support for new Autoconf macros:
1059 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
1061 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
1062 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
1063 in different directories. However, only one instance of such a
1064 library objects directory is supported.
1066 * Change to Libtool support:
1068 - Libtool generic flags (those that go before the --mode=MODE option)
1069 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
1071 * Yacc and Lex changes:
1073 - The rebuild rules for distributed Yacc and Lex output will avoid
1074 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
1077 - ylwrap is now always used for lex and yacc source files,
1078 regardless of whether there is more than one source per directory.
1080 * Languages changes:
1082 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
1083 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
1084 tracking, unlike non-preprocessed assembler (*.s).
1086 - subdir-object mode works now with Assembler. Automake assumes
1087 that the compiler understands `-c -o'.
1089 - Preprocessed assembler (*.S) compilation now also honors
1090 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
1092 - Improved support for Objective C:
1093 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
1094 - A new section of the manual documents the support.
1096 - New support for Unified Parallel C:
1097 - AM_PROG_UPC looks for a UPC compiler.
1098 - A new section of the manual documents the support.
1100 - Per-target flags are now correctly handled in link rules.
1102 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
1103 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
1104 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
1105 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
1107 The fix for compiler flags (i.e., using maude_CFLAGS instead of
1108 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
1109 is expected to work (and actually works during compilation).
1111 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
1112 "in addition to" breaks backward compatibility with older versions.
1113 If your package used both variables, as in
1115 AM_LDFLAGS = common flags
1116 bin_PROGRAMS = a b c
1117 a_LDFLAGS = more flags
1120 and assumed *_LDFLAGS would sum up, you should rewrite it as
1122 AM_LDFLAGS = common flags
1123 bin_PROGRAMS = a b c
1124 a_LDFLAGS = $(AM_LDFLAGS) more flags
1127 This new behavior of *_LDFLAGS is more coherent with other
1128 per-target variables, and the way *_LDFLAGS variables were
1129 considered internally.
1131 * New installation targets:
1133 - New targets mandated by GNU Coding Standards:
1138 By default they will only install Texinfo manuals.
1139 You can customize them with *-local variants:
1145 - The undocumented recursive target `uninstall-info' no longer exists.
1146 (`uninstall' is in charge of removing all possible documentation
1147 flavors, including optional formats such as dvi, ps, or info even
1148 when `no-installinfo' is used.)
1150 * Miscellaneous changes:
1152 - Automake no longer complains if input files for AC_CONFIG_FILES
1153 are specified using shell variables.
1155 - clean, distribution, or rebuild rules are normally disabled for
1156 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
1157 AC_CONFIG_LINK specified using shell variables. However, if these
1158 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
1159 be able to output rules anyway.
1160 (See the Automake documentation for AC_CONFIG_FILES.)
1162 - $(EXEEXT) is automatically appended to filenames of TESTS
1163 that have been declared as programs in the same Makefile.
1164 This is mostly useful when some check_PROGRAMS are listed in TESTS.
1166 - `-Wportability' has finally been turned on by default for `gnu' and
1167 `gnits' strictness. This means, automake will complain about %-rules
1168 or $(GNU Make functions) unless you switch to `foreign' strictness or
1169 use `-Wno-portability'.
1171 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
1172 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
1173 $(mkdir_p) variable is still defined (to the same value as
1174 $(MKDIR_P)) but should be considered obsolete. If you are using
1175 $(mkdir_p) in some of your rules, please plan to update them to
1176 $(MKDIR_P) at some point.
1178 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
1179 They still work in this release, but may be withdrawn in a future one.
1181 - Inline compilation rules for gcc3-style dependency tracking are
1184 - Automake installs a "Hello World!" example package in $(docdir).
1185 This example is used throughout the new "Autotools Introduction"
1186 chapter of the manual.
1188 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1192 * Makefile.in bloat reduction:
1194 - Inference rules are used to compile sources in subdirectories when
1195 the `subdir-objects' option is used and no per-target flags are
1196 used. This should reduce the size of some projects a lot, because
1197 Automake used to output an explicit rule for each such object in
1200 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1201 object that must be built with explicit rules. It just outputs
1202 the rules required to build the kind of object considered: either
1203 the two .o and .obj rules for usual objects, or the .lo rule for
1206 * Change to Libtool support:
1208 - Libtool tags are used with libtool versions that support them.
1209 (I.e., with Libtool 1.5 or greater.)
1211 - Automake is now able to handle setups where a libtool library is
1212 conditionally installed in different directories, as in
1215 lib_LTLIBRARIES = liba.la
1217 pkglib_LTLIBRARIES = liba.la
1219 liba_la_SOURCES = ...
1221 * Changes to aclocal:
1223 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1224 really evaluated, before it decides to include them in aclocal.m4.
1225 This solves nasty problems with conditional redefinitions of
1226 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1227 *.m4 files to be included in any project using these macros.
1228 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1229 most famous instance of this bug.)
1231 - Do not complain about missing conditionally AC_REQUIREd macros
1232 that are not actually used. In 1.8.x aclocal would correctly
1233 determine which of these macros were really needed (and include
1234 only these in the package); unfortunately it would also require
1235 all of them to be present in order to run. This created
1236 situations were aclocal would not work on a tarball distributing
1237 all the macros it uses. For instance running aclocal on a project
1238 containing only the subset of the Gettext macros in use by the
1239 project did not work, because gettext conditionally requires other
1242 * Portability improvements:
1244 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1245 tar-pax. The new option filename-length-max=99 helps diagnosing
1246 filenames that are too long for tar-v7. (PR/414)
1248 - Variables aumented with `+=' are now automatically flattened (i.e.,
1249 trailing backslashes removed) and then wrapped around 80 colummns
1250 (adding trailing backslashes). In previous versions, a long series
1256 would result in a single-line definition of VAR that could possibly
1257 exceed the maximum line length of some make implementations.
1259 Non-augmented variables are still output as they are defined in
1264 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1265 Works the same as the old Fortran 77 implementation; just replace
1266 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1267 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1269 - Support for conditional _LISP.
1271 - Support for conditional -hook and -local rules (PR/428).
1273 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1275 - Automake will not write any Makefile.ins after the first error it
1276 encounters. The previous Makefile.ins (if any) will be left in
1277 place. (Warnings will not prevent output, but remember they can
1278 be turned into errors with -Werror.)
1280 - The restriction that SUBDIRS must contain direct children is gone.
1283 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1284 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1286 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1288 Bugs fixed in 1.8.5:
1290 * Long-standing bugs:
1292 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1293 so that `make distclean' and `make maintainer-clean' can work.
1295 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1297 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1299 - Polish diagnostic when no input file is found.
1301 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1303 Bugs fixed in 1.8.4:
1305 * Long-standing bugs:
1307 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1308 overridden by the user.
1310 - Honor PATH_SEPARATOR in various places of the Automake package, for
1313 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1316 - Fix install-sh so it can install the `mv' binary... using `mv'.
1318 - Fix tru64 dependency tracking for libtool objects.
1320 - Work around Exuberant Ctags when creating a TAGS files in a directory
1321 without files to scan but with subdirectories to include.
1323 * Bugs introduced by 1.8:
1325 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1326 not defined in the same conditions as the _LDADD that uses it.
1328 - Do not warn when JAVAROOT is overridden, this is legitimate.
1330 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1332 Bugs fixed in 1.8.3:
1334 * Long-standing bugs:
1336 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1337 or any of the other *dir variables contain a space.
1339 Please note that Automake does not and cannot support spaces in
1340 filenames that are involved during the build. This change affects
1341 only installation paths, so that `make install' does not bomb out
1342 in packages configured with
1343 ./configure --prefix '/c/Program Files'
1345 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1346 POSIXLY_CORRECT is set.
1348 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1349 since Autoconf 2.54, which defines LIBOBJS itself.
1351 - Fix a potential (but unlikely) race condition in parallel elisp
1352 builds. (Introduced in 1.7.3.)
1354 - Do not assume that users override _DEPENDENCIES in all conditions
1355 where Automake will try to define them.
1357 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1358 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1361 This fix also affects the $(mkdir_p) variable defined since
1362 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1363 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1365 - Secure temporary directory creation in `make distcheck'. (PR/413)
1367 - Do not generate two build rules for `parser.h' when the
1368 parser appears in two different conditionals.
1370 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1371 checking. Usually ./configure will not pick this shell; so this
1372 fix only helps cases where the shell is forced to /bin/sh.
1374 * Bugs introduced by 1.8:
1376 - In some situations (hand-written `m4_include's), aclocal would
1377 call the `File::Spec->rel2abs' method, which was only introduced
1378 in Perl 5.6. This new version reestablish support Perl 5.005.
1380 It is likely that the next major Automake releases will require at
1381 least Perl 5.6. Consider upgrading your development environment
1382 if you are still using the five-year-old Perl 5.005.
1384 - Automake would sometimes fail to define rules for targets listed
1385 in variables defined in multiple conditions. For instance on
1391 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1392 `b.$(OBJEXT): b.c' rule.
1394 * New sections in manual:
1396 - Third-Party Makefiles: how to interface third party Makefiles.
1397 - Upgrading: upgrading packages to newer Automake versions.
1398 - Multiple Outputs: handling tools that produce many outputs.
1400 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1404 * A (well known) portability bug slipped in the changes made to
1405 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1406 install anything on Tru64.
1408 * Fix install rules for conditionally built python files. (This never
1411 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1415 * Bugs introduced by 1.8:
1417 - Fix Config.pm import error with old Perl versions (at least
1418 5.005_03). One symptom is that aclocal could not find its macro
1421 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1422 created by `make install' are always world readable, even if the
1423 installer happens to have an overly restrictive umask (e.g. 077).
1424 This was a mistake and has been reverted. There are at least two
1425 reasons why we must not use `-m 0755':
1426 - it causes special bits like SGID to be ignored,
1427 - it may be too restrictive (some setups expect 775 directories).
1429 - Fix aclocal to honor definitions located in files which have been
1430 m4_included manually. aclocal 1.8 had been updated to check
1431 m4_included files for new requirements, but forgot that these
1432 m4_included files can also provide new definitions.
1434 Note that if you have such a setup, we recommend you get rid of
1435 it. In the past, there was a reason to m4_include files manually:
1436 aclocal used to duplicate entire M4 files into aclocal.m4, even
1437 files that were distributed. Some packages were therefore
1438 m4_including the distributed file directly, and playing some
1439 tricks to ensure aclocal would not copy that file to aclocal.m4,
1440 in order to limit the amount of duplication. Since aclocal 1.8.x
1441 will precisely output m4_includes for local M4 files, we recommend
1442 that you clean up your setup, removing all manual m4_includes and
1443 letting aclocal output them.
1445 - Output detailed menus in the Info version if the Automake manual,
1446 so that Emacs can locate the indexes.
1448 - configure.ac and configure were listed twice in DIST_COMMON (an
1449 internal variable where Automake lists configury files to
1450 distribute). This was harmless, but unaesthetic.
1452 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1453 This was an issue only in the Automake package itself, not in
1456 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1457 DEST:SRC. This was wrong, as some packages do
1458 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1461 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1462 argument. This caused two kinds of failures:
1463 - Rules installing data in a conditionally defined directory
1464 failed when that directory was undefined. In this case no
1465 argument was supplied.
1466 - `make installdirs' failed, because several directories were
1467 passed to $(mkdir_p). This was an issue only on platform
1468 were $(mkdir_p) is implemented with `install-sh -d'.
1469 $(mkdir_p) as been changed to accept 0 or more arguments, as
1472 * Long-standing bugs:
1474 - Fix an unexpected diagnostic occurring when users attempt
1475 to override some internal variables that Automake appends to.
1477 - aclocal now scans configure.ac for macro definitions (PR/319).
1479 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1480 distributes files which are outside itself (this usually occurs
1481 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1482 from a parent package), then `make distcheck' fails due to an
1483 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1484 (tests/subpkg2.test failure)
1486 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1487 In a VPATH-build configuration, `make install' would install
1488 nobase_ files to wrong locations.
1490 - Fix a Perl `uninitialized value' diagnostic occurring when
1491 automake complains that a Texinfo file does not have a
1492 @setfilename statement.
1494 - Erase config.status.lineno during `make distclean'. This file
1495 can be created by config.status. Automake already knew about
1496 configure.lineno, but forgot config.status.lineno.
1498 - Distribute all files, even those which are built and installed
1499 conditionally. This change affects files listed in conditionally
1500 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1501 as well as those listed in conditionally defined dist_*_DATA,
1502 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1504 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1505 doesn't conform to POSIX.
1507 - Normalize help strings for configure variables and options added
1512 - Check for python2.4 in AM_PATH_PYTHON.
1514 * Spurious failures in test suite:
1516 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1517 tests/ltconv.test: fix failures with CVS Libtool.
1518 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1519 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1520 fix failures with old Texinfo versions.
1522 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1528 - The NEWS file is more verbose.
1532 - Autoconf 2.58 or greater is required.
1536 - Default source file names in the absence of a _SOURCES declaration
1537 are made by removing any target extension before appending `.c', so
1538 to make the libtool module `foo.la' from `foo.c', you only need to
1541 lib_LTLIBRARIES = foo.la
1542 foo_la_LDFLAGS = -module
1544 For backward compatibility, foo_la.c will be used instead of
1545 foo.c if this file exists or is the explicit target of a rule.
1546 However -Wobsolete will warn about this deprecated naming.
1548 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1549 of being hard-coded in each $(AR) invocation, so they can be
1550 substituted from configure.ac. This has been requested by people
1551 dealing with non-POSIX ar implementations.
1553 - New warning option: -Woverride. This will warn about any user
1554 target or variable definitions which override Automake
1557 - Texinfo rules back up and restore info files when makeinfo fails.
1559 - Texinfo rules now support the `html' target.
1560 Running this requires Texinfo 4.0 or greater.
1562 `html' is a new recursive target, so if your package mixes
1563 hand-crafted `Makefile.in's with Automake-generated
1564 `Makefile.in's, you should adjust the former to support (or
1565 ignore) this target so that `make html' recurses successfully. If
1566 you had a custom `html' rule in your `Makefile.am', it's better to
1567 rename it as `html-local', otherwise your rule will override
1568 Automake's new rule (you can check that by running `automake
1569 -Woverride') and that will stop the recursion to subdirectories.
1571 Last but not least, this `html' rule is declared PHONY, even when
1572 overridden. Fortunately, it appears that few packages use a
1573 non-PHONY `html' rule.
1575 - Any file which is m4_included from configure.ac will appear as a
1576 configure and Makefile.in dependency, and will be automatically
1579 - The rules for rebuilding Makefiles and Makefile.ins will now
1580 rebuild all Makefiles and all Makefile.ins at once when one of
1581 configure's dependencies has changed. This is considerably faster
1582 than previous implementations, where config.status and automake
1583 were run separately in each directory (this still happens when you
1584 change a Makefile.am locally, without touching configure.ac or
1585 friends). Doing this also solves a longstanding issue: these
1586 rebuild rules failed to work when adding new directories to the
1587 tree, forcing you to run automake manually.
1589 - For similar reasons, the rules to rebuild configure,
1590 config.status, and aclocal.m4 are now defined in all directories.
1591 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1592 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1593 should better define them in all directories. This is easily done
1594 using an AC_SUBST (make sure you prefix these dependencies with
1595 $(top_srcdir) since this variable will appear at different
1596 levels of the build tree).
1598 - aclocal will now use `m4_include' instead of copying local m4
1599 files into aclocal.m4. (Local m4 files are those you ship with
1600 your project, other files will be copied as usual.)
1602 Because m4_included files are automatically distributed, it means
1603 for most projects there is no point in EXTRA_DISTing the list of
1604 m4 files which are used. (You can probably get rid of
1605 m4/Makefile.am if you had one.)
1607 - aclocal will avoid touching aclocal.m4 when possible, so that
1608 Autom4te's cache isn't needlessly invalidated. This behavior can
1609 be switched off with the new `--force' option.
1611 - aclocal now uses Autoconf's --trace to detect macros which are
1612 actually used and will no longer include unused macros simply
1613 because they where mentioned. This was often the case for macros
1614 called conditionally.
1616 - New options no-dist and no-dist-gzip.
1618 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1619 py-compile, and ylwrap, now all understand --version and --help.
1621 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1622 links as part of the distclean target and including source files in
1625 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1626 argument. The latter can be used to override the default behavior
1627 (which is to abort).
1629 - Automake will exit with $? = 63 on version mismatch. (So does
1630 Autoconf 2.58) missing knows this, and in this case it will
1631 emulate the tools as if they were absent. Because older versions
1632 of Automake and Autoconf did not use this exit code, this change
1633 will only be useful in projects generated with future versions of
1636 - When using AC_CONFIG_FILES with multiple input files, Automake
1637 generates the first ".in" input file for which a ".am" exists.
1638 (Former versions would try to use only the first input file.)
1640 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1641 idiom to disable byte-compilation of lisp_LISP files, it is
1642 recommended that you switch to using lisp_DATA. Note that
1643 this is not strictly equivalent: lisp_DATA will install elisp
1644 files even if emacs is not installed, while *_LISP do not
1645 install anything unless emacs is found.
1647 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1648 available. This selection is achieved through the Makefile
1649 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1650 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1651 `$(install_sh) -m 0755 -d'.
1655 - Because `mkdir -p' is available on most platforms, and we can use
1656 `install-sh -d' when it is not, the use of the mkinstalldirs
1657 script is being phased out. `automake --add-missing' no longer
1658 installs it, and if you remove mkinstalldirs from your package,
1659 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1661 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1662 gettextize and autopoint will install it when needed. Automake
1663 will continue to define the $(mkinstalldirs) and to distribute
1664 mkinstalldirs when this script is in the source tree.
1666 - AM_PROG_CC_STDC is now empty. The content of this macro was
1667 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1668 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1669 renaming should be safe, even if you have to support several,
1670 versions of Automake, because AC_PROG_CC defines this variable
1671 since Autoconf 2.54.)
1673 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1674 variable to override the aclocal.m4 dependencies computed
1675 (inaccurately) by older versions of Automake. Because Automake
1676 now tracks configure's m4 dependencies accurately (see m4_include
1677 above), the use of ACLOCAL_M4_SOURCES should be considered
1678 obsolete and will be flagged as such when running `automake
1683 - Defining programs conditionally using Automake conditionals no
1684 longer leads to a combinatorial explosion. The following
1685 construct used to be troublesome when used with dozens of
1700 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1702 - Due to implementation constraints, previous versions of Automake
1703 proscribed multiple conditional definitions of some variables
1713 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1714 This restriction has been lifted, and these variables now
1715 support multiple conditional definitions as do other variables.
1717 - Cleanup the definitions of $(distdir) and $(top_distdir).
1718 $(top_distdir) now points to the root of the distribution
1719 directory created during `make dist', as it did in Automake 1.4,
1720 not to the root of the build tree as it did in intervening
1721 versions. Furthermore these two variables are now only defined in
1722 the top level Makefile, and passed to sub-directories when running
1725 - The --no-force option now correctly checks the Makefile.in's
1726 dependencies before deciding not to update it.
1728 - Do not assume that make files are called Makefile in cleaning rules.
1730 - Update .info files in the source tree, not in the build tree. This
1731 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1732 used to update these files in the build tree (previous versions did
1733 it in the source tree too), and it caused several problems, varying
1734 from mere annoyance to portability issues.
1736 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1737 when --add-missing and --force-missing are used. For backward
1738 compatibility --add-missing will continue to install COPYING (in
1739 `gnu' strictness) when none of these three files exist, but this
1740 use is deprecated: you should better choose a license yourself and
1741 install it once for all in your source tree (and in your code
1744 - Fix ylwrap so that it does not overwrite header files that haven't
1745 changed, as the inline rule already does.
1747 - User-defined rules override automake-defined rules for the same
1748 targets, even when rules do not have commands. This is not new
1749 (and was documented), however some of the automake-generated
1750 rules have escaped this principle in former Automake versions.
1751 Rules for the following targets are affected by this fix:
1753 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1754 info, info-am, install-data-am, install-exec-am, install-info,
1755 install-info-am, install-man, installcheck-am, maintainer-clean,
1756 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1757 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1759 Practically it means that an attempt to supplement the dependencies
1760 of some target, as in
1762 clean: my-clean-rule
1764 will now *silently override* the automake definition of the
1765 rule for this target. Running `automake -Woverride' will diagnose
1766 all such overriding definitions.
1768 It should be noted that almost all of these targets support a *-local
1769 variant that is meant to supplement the automake-defined rule
1770 (See node `Extending' in the manual). The above rule should
1773 clean-local: my-clean-rule
1775 These *-local targets have been documented since at least
1776 Automake 1.2, so you should not fear the change if you have
1777 to support multiple automake versions.
1781 - The Automake manual is now distributed under the terms of the GNU FDL.
1783 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1785 - core dumps are no longer removed by the cleaning rules. There are
1786 at least three reasons for this:
1787 1. These files should not be created by any build step,
1788 so their removal do not fit any of the cleaning rules.
1789 Actually, they may be precious to the developer.
1790 2. If such file is created during a build, then it's clearly a
1791 bug Automake should not hide. Not removing the file will
1792 cause `make distcheck' to complain about its presence.
1793 3. Operating systems have different naming conventions for
1794 core dump files. A core file on one system might be a
1795 completely legitimate data file on another system.
1797 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1798 defined by Automake. This means that any definition in the
1799 environment will be used, unless overridden in the Makefile.am or
1800 on the command line. The old behavior, where these variables were
1801 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1802 AC_ARG_VARing each variable from configure.ac.
1804 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1805 documented. (The is not a new feature, these variables have
1806 been there since at least Automake 1.4.)

1859 * Fix output of aclocal.m4 dependencies in subdirectories.
1860 * Use `mv -f' instead of `mv' in fastdep rules.
1861 * Upgrade mdate-sh to work on OS/2.
1862 * Don't byte-compile elisp files when ELCFILES is set empty.
1863 (this documented feature was broken by 1.7.3)
1864 * Diagnose trailing backslashes on last line of Makefile.am.
1865 * Diagnose whitespace following trailing backslashes.

1870 * Minor documentation fixes.
1872 Bugs fixed in 1.7.3:
1873 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1874 * Query distutils for `pythondir' and `pythonexecdir', instead of
1875 using an hardcoded path. This should allow builds on 64-bit
1876 distributions that usually use lib64/ instead of lib/.
1877 * AM_PATH_PYTHON will also search for python2.3.
1878 * elisp files are now built all at once instead of one by one. Besides
1879 incurring a speed-up, this is required to support interdependent elisp files.
1880 * Support for DJGPP:
1881 - `make distcheck' will now work in `_inst/' and `_build' instead
1882 of `=inst/' and `=build/'
1883 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1884 - install/uninstall `*.i[0-9][0-9]'-style info files
1885 - more changes that affect only the Automake package (not its output)
1886 * Fix some incompatibilities with upcoming perl-5.10.
1887 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1888 PACKAGE and VERSION.
1890 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1891 is troublesome with gcc and Solaris compilers. (PR/385)
1892 - makedepend mode: work with Libtool. (PR/385 too)
1894 * better support for unusual gettext setups, such as multiple po/ directories
1896 - Flag missing po/ and intl/ directories as warnings, not errors.
1897 - Disable these warnings if po/ does not exist.
1898 * Noteworthy manual updates:
1900 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1902 - Document `AM_YFLAGS = -d'. (PR/382)
1904 Bugs fixed in 1.7.2:
1905 * Fix installation and uninstallation of Info files built in subdirectories.
1906 * Do not run `./configure --with-included-gettext' during `make distcheck'
1907 if AM_GNU_GETTEXT([external]) is used.
1908 * Correctly uninstall renamed man pages.
1909 * Do not strip escaped newline in variables defined in one condition
1910 and augmented in another condition.
1911 * Fix ansi2knr rules for LIBOBJS sources.
1912 * Clean all known Texinfo index files, not only those which appear to
1913 be used, because we cannot know which indexes are used in included files.
1914 (PR/375, Debian Bug #168671)
1915 * Honor only the first @setfilename seen in a Texinfo file.
1916 * Treat "required file X not found" diagnostics as errors (exit status 1).
1917 * Don't complain that a required file is not found when it is a Makefile
1919 * Don't use single suffix inference rules when building `.info'-less
1920 Info files, for the sake of Solaris make.
1921 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1922 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1923 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1924 * Fix building of deansified files from subdirectories. (PR/370)
1925 * Add missing `fi' in the .c->.obj rules.
1926 * Improve install-sh to work even when names contain spaces or certain
1927 (but not all) shell metachars.
1928 * Fix the following spurious failures in the test suite:
1929 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1930 * Noteworthy manual updates:
1931 - Augment the section about BUILT_SOURCES.
1932 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1934 Bugs fixed in 1.7.1:
1935 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1937 * Aclocal should now recognize macro names containing parentheses, e.g.
1938 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1939 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1941 * Install Python files even if they were built. (PR/369)
1942 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1943 version might not be defined in the latter. (PR/358)
1944 * Reorder arguments passed to a couple of commands, so things works
1945 when POSIXLY_CORRECT=1.
1946 * Fix a regex that can cause Perl to segfault on large input.
1948 * Fix distribution of packages that have some sources defined conditionally,
1949 as in the `Conditional compilation using Automake conditionals' example
1951 * Fix spurious test suite failures on IRIX.
1952 * Don't report a required variable as undefined if it has been
1953 defined conditionally for the "right" conditions.
1954 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1955 `make distcheck' fails.
1956 * Fix distribution of included Makefile fragment, so we don't create
1957 spurious directories in the distribution. (PR/366)
1958 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1961 * Autoconf 2.54 is required.
1962 * `aclocal' and `automake' will no longer warn about obsolete
1963 configure macros. This is done by `autoconf -Wobsolete'.
1964 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1965 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1966 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1967 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1968 `configure.ac' for you.
1969 * Support for per-program and per-library `_CPPFLAGS'.
1970 * New `ctags' target (builds CTAGS files).
1971 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1972 (see `automake --help' or the manual for a list of them).
1973 * Honor the WARNINGS environment variable.
1974 * Omit the call to depcomp when using gcc3: call the compiler directly.
1975 * A new option, std-options, tests that programs support --help and --version
1976 when `make installcheck' is run. This is enabled by --gnits.
1977 * Texinfo rules now support the `ps' and `pdf' targets.
1978 * Info files are now created in the build directory, not the source directory.
1979 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1981 * `make distcheck' will enforce DESTDIR support by attempting
1983 * `+=' can be used in conditionals, even if the augmented variable
1984 was defined for another condition.
1985 * Makefile fragments (inserted with `include') are always distributed.
1986 * Use Autoconf's --trace interface to inspect configure.ac and get
1987 a more accurate view of it.
1988 * Add support for extending aclocal's default macro search path
1989 using a `dirlist' file within the aclocal directory.
1990 * automake --output-dir is deprecated.
1991 * The part of the distcheck target that checks whether uninstall actually
1992 removes all installed files has been moved in a separate target,
1993 distuninstallcheck, so it can be overridden easily.
1997 * Support for AM_INIT_GETTEXT([external])
1998 * Bug fixes, including:
1999 - Fix Automake's own `make install' so it works even if `ln' doesn't.
2000 - nobase_ programs and scripts honor --program-transform correctly.
2001 - Erase configure.lineno during `make distclean'.

2017 - Don't choke on AM_LDFLAGS definitions.
2018 - Clean libtool objects from subdirectories.
2019 - Allow configure variables with reserved suffix and unknown prefix
2020 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
2021 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
2024 * Autoconf 2.52 is required.
2025 * automake no longer run libtoolize.
2026 This is the job of autoreconf (from GNU Autoconf).
2027 * `dist' generates all the archive flavors, as did `dist-all'.
2028 * `dist-gzip' generates the Gzip tar file only.
2029 * Combining Automake Makefile conditionals no longer lead to a combinatorial
2030 explosion. Makefile.in's keep a reasonable size.
2031 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
2032 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
2034 * `#line' of Lex and Yacc files are properly set.
2035 * EXTRA_DIST can contain generated directories.
2036 * Support for dot-less extensions in suffix rules.
2037 * The part of the distcheck target that checks whether distclean actually
2038 cleans all built files has been moved in a separate target, distcleancheck,
2039 so it can be overridden easily.
2040 * `make distcheck' will pass additional options defined in
2041 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
2042 * Fixed CDPATH portability problems, in particular for MacOS X.
2043 * Fixed handling of nobase_ targets.

2047 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
2048 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
2049 (Note that "pkgname" is not "tarname", see the manual for details.)
2050 It is also possible to pass a list of global Automake options as
2051 first argument to this new form of AM_INIT_AUTOMAKE.
2052 * Compiler-based assembler is now called `CCAS'; people expected `AS'
2053 to be a real assembler.
2054 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
2055 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
