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33 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002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36 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002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 - The 'color-tests' option is now unconditionally activated by default.
55 In particular, this means that testsuite output is now colorized by
56 default if the attached terminal seems to support ANSI escapes, and
57 that the user can force output colorization by setting the variable
58 AM_COLOR_TESTS to "always". The 'color-tests' is still recognized
59 for backward-compatibility, although it's a handled as a no-op now.
61 * Silent rules support:
63 - Support for silent rules is now always active in Automake-generated
64 Makefiles. So, although the verbose output is still the default,
65 the user can now always use "./configure --enable-silent-rules" or
66 "make V=0" to enable quieter output in the package he's building.
68 - The 'silent-rules' option has now become a no-op, preserved for
69 backward-compatibility only. In particular, its use does not disable
70 the warnings in the 'portability-recursive' category anymore.
74 - The rules to build PDF and DVI files from Texinfo input now use the
75 ' --build-dir' option, to keep the auxiliary files used by texi2dvi
76 and texi2pdf around without cluttering the build directory, and to
77 make it possible to run the "dvi" and "pdf" recipes in parallel.
79 * Automatic remake rules and 'missing' script:
81 - The 'missing' script does not try anymore to update the timestamp
82 of out-of-date files that require a maintainer-specific tool to be
83 remade, in case the user lacks such a tool (or has a too-old version
84 of it). It just give a useful warning, and in some cases also a tip
85 about how to obtain such a tool.
87 - The missing script has thus become useless as a (poor) way to work
88 around the sketched-timestamps issues that can happen for projects
89 that keep generated files committed in their VCS repository. Such
90 projects are now encouraged to write a custom "fix-timestamps.sh"
91 script to avoid such issues; a simple example is provided in the
92 "CVS and generated files" chapter of the automake manual.
96 The user can now define his own recursive targets that recurse
97 in the directories specified in $(SUBDIRS). This can be done by
98 specifying the name of such targets in invocations of the new
99 'AM_EXTRA_RECURSIVE_TARGETS' m4 macro.
101 * Improvements to aclocal and related rebuilds rules:
103 - The Autoconf-provided macro AC_CONFIG_MACRO_DIR is now traced by
104 aclocal, and can be used to declare the local m4 include directory.
105 Formerly, one had to specify it with an explicit '-I' option to the
106 'aclocal' invocation.
108 - The special make variable ACLOCAL_AMFLAGS is deprecated; future
109 Automake versions will warn about its use, and later version will
110 remove support for it altogether.
112 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
116 * WARNING: Future backward-incompatibilities!
118 - Future versions of Automake will likely drop support for the
119 long-deprecated 'configure.in' name for the Autoconf input file.
120 You are advised to use the recommended name 'configure.ac' instead.
122 - Starting from the next major Automake version (1.13), the rules to
123 build pdf, ps and dvi output from Texinfo input will use the '--tidy'
124 option by default. Since such an option was introduced in Texinfo
125 4.9, this means that Makefiles generated by future Automake versions
126 will require at least that version of Texinfo.
128 - Starting from the next major Automake version (1.13), the parallel
129 testsuite harness (previously only enabled by the 'parallel-tests'
130 option) will become the default one; the older serial testsuite
131 harness will still be available through the use of the 'serial-tests'
134 - Support for the two- and three-arguments invocation forms of the
135 AM_INIT_AUTOMAKE macro is deprecated, and will be removed in the
136 next major Automake version (1.13).
138 - The exact order in which the directories in the aclocal macro
139 search path are looked up is probably going to be changed in the
140 next Automake release (1.13).
142 - The 'missing' script will not try anymore to update the timestamp
143 of out-of-date files that require a maintainer-specific tool to be
144 remade, in case the user lacks such a tool (or has a too-old version
145 of it). In fact, starting from Automake 1.13, all it'll do will be
146 giving more useful warnings than a bare "command not found" from a
151 - The '.m4' files provided by Automake does not define serial numbers
152 anymore. This should cause no difference in the behaviour of aclocal
155 * Automake Testsuite:
157 - Some testsuite weaknesses and spurious failures have been fixed.
159 * Long-standing bugs:
161 - Instead of renaming only self-references of files (typically for
162 #lines), ylwrap now also renames references to the other generated
163 files. This fixes support for GLR and C++ parsers from Bison (PR
164 automake/491 and automake bug#7648): 'parser.c' now properly
165 #includes 'parser.h' instead of 'y.tab.h'.
167 - Generated files unknown to ylwrap are now preserved. This fixes
168 C++ support for Bison (automake bug#7648): location.hh and the
169 like are no longer discarded.
171 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
175 * Warnings and deprecations:
177 - Automake now issues a warning (in the 'portability' category) if
178 'configure.in' is used instead of 'configure.ac' as the Autoconf
179 input file. Such a warning will also be present in the next
180 Autoconf version (2.70).
184 - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
185 order (as done by the other recursive rules), rather than in the
186 inverse order. They used to do that in order to work a round a
187 limitation in an older implementation of the automatic dependency
188 tracking support, but that limitation had been lifted years ago
189 already, when the automatic dependency tracking based on side-effects
190 of compilation had been introduced.
192 - Cleaning rules for compiled objects (both "plain" and libtool) work
193 better when subdir objects are involved, not triggering a distinct
194 'rm' invocation for each such object. They do so by removing *any*
195 compiled object file that is in the same directory of a subdir
196 object. See automake bug#10697.
198 * Silent rules support:
200 - A new predefined $(AM_V_P) make variable is provided; it expands
201 to a shell conditional that can be used in recipes to know whether
202 make is being run in silent or verbose mode.
204 Bugs fixed in 1.12.2:
206 * SECURITY VULNERABILITIES!
208 - The 'distcheck' recipe no longer grants temporary world-write
209 permissions on the extracted distdir. Even if such rights were
210 only granted for a vanishingly small time window, the implied
211 race condition proved to be enough to allow a local attacker
212 to run arbitrary code with the privileges of the user running
213 "make distcheck". This is CVE-2012-3386.
215 * Long-standing bugs:
217 - The "recheck" targets behaves better in the face of build failures
218 related to previously failed tests. For example, if a test is a
219 compiled program that must be rerun by "make recheck", and its
220 compilation fails, it will still be rerun by further "make recheck"
221 invocations. See automake bug#11791.
223 * Bugs introduced by 1.12.1:
225 - Automake provides once again the '$(mkdir_p)' make variable and the
226 '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
227 for better backward-compatibility.
229 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
233 * New supported languages:
235 - Support for Objective C++ has been added; it should work similarly to
236 the support for Objective C.
238 * Deprecated obsolescent features:
240 - Use of the long-deprecated two- and three-arguments invocation forms
241 of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
242 category. Starting from the next major Automake release (1.13), such
243 usages won't be allowed anymore.
245 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
246 now deprecated (its use triggers a warning in the 'obsolete' category).
247 It will be removed in the next major Automake release (1.13).
249 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
250 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
251 m4 macro are deprecated, eliciting a warning in the 'obsolete'
254 * Miscellaneous changes:
256 - The Automake test cases now require a proper POSIX-conforming shell.
257 Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) won't be
258 accepted anymore. In most cases, the user shouldn't have to specify
259 such POSIX shell explicitly, since it will be looked up at configure
260 time. Still, when this lookup fails, or when the user wants to
261 override its conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be
262 used (pointing to the shell that will be used to run the Automake
265 Bugs fixed in 1.12.1:
267 * Bugs introduced by 1.12:
269 - Several weaknesses in Automake's own build system and test suite
272 * Bugs introduced by 1.11.3:
274 - When given non-option arguments, aclocal rejects them, instead of
275 silently ignoring them.
277 * Long-standing bugs:
279 - When the 'color-tests' option is in use, forcing of colored testsuite
280 output through "AM_COLOR_TESTS=always" works even if the terminal is
281 a non-ANSI one, i.e., if the TERM environment variable has a value of
284 - Several inefficiencies and poor performances in the implementation
285 of the parallel-tests 'check' and 'recheck' targets have been fixed.
287 - The post-processing of output "#line" directives done the ylwrap
288 script is more faithful w.r.t. files in a subdirectory; for example,
289 if the processed file is "src/grammar.y", ylwrap will correctly
290 produce directives like:
291 #line 7 "src/grammar.y"
296 * Bugs with new Perl versions:
298 - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
300 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
304 * Obsolete features removed:
306 - The never documented nor truly used script 'acinstall' has been
309 - Support for automatic de-ANSI-fication has been removed.
311 - The support for the "obscure" multilib feature has been removed
312 from Automake core (but remains available in the 'contrib/'
313 directory of the Automake distribution).
315 - Support for ".log -> .html" conversion and the check-html and
316 recheck-html targets has been removed from Automake core (but
317 remains available in the 'contrib/' directory of the Automake
320 - The deprecated 'lzma' compression format for distribution archives
321 has been removed, in favor of 'xz' and 'lzip'.
323 - The obsolete AM_WITH_REGEX macro has been removed.
325 - The long-deprecated options '--output-dir', '--Werror' and
326 '--Wno-error' have been removed.
328 - The chapter on the history of Automake has been moved out of the
329 reference manual, into a new dedicated Texinfo file.
333 - New 'cscope' target to build a cscope database for the source tree.
335 * Changes to Automake-generated testsuite harnesses:
337 - The new automake option 'serial-tests' has been introduced. It can
338 be used to explicitly instruct automake to use the older serial
339 testsuite harness. This is still the default at the moment, but it
340 might change in future versions.
342 - The 'recheck' target (provided by the parallel testsuite harness) now
343 depends on the 'all' target. This allows for a better user-experience
344 in test-driven development. See automake bug#11252.
346 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
347 and unexpected or internal error, or a failure to set up the test case
348 scenario) have their outcome reported as an 'ERROR' now. Previous
349 versions of automake reported such an outcome as a 'FAIL' (the only
350 difference with normal failures being that hard errors were counted
351 as failures even when the test originating them was listed in
354 - The testsuite summary displayed by the parallel-test harness has a
355 completely new format, that always list the numbers of passed, failed,
356 xfailed, xpassed, skipped and errored tests, even when these numbers
357 are zero (but using smart coloring when the color-tests option is in
360 - The default testsuite driver offered by the 'parallel-tests' option is
361 now implemented (partly at least) with the help of automake-provided
362 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
363 on code in the generated Makefile.in.
364 This has two noteworthy implications. The first one is that projects
365 using the 'parallel-tests' option should now either run automake with
366 the '--add-missing' option, or manually copy the 'test-driver' script
367 into their tree. The second, and more important, implication is that
368 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
369 not be used anymore to define a test runner, and the command specified
370 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
371 program or script. For example, this is still a valid usage (albeit
374 TESTS_ENVIRONMENT = \
375 if test -n '$(STRICT_TESTS)'; then \
376 maybe_errexit='-e'; \
380 LOG_COMPILER = $(SHELL) $$maybe_errexit
382 while this is not anymore:
384 TESTS_ENVIRONMENT = \
385 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
389 TESTS_ENVIRONMENT = \
390 run_with_perl_or_shell () \
392 if grep -q '^#!.*perl' $$1; then
398 LOG_COMPILER = run_with_perl_or_shell
400 - The package authors can now use customary testsuite drivers within
401 the framework provided by the 'parallel-tests' testsuite harness.
402 Consistently with the existing syntax, this can be done by defining
403 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
405 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
406 to redirect/define file descriptors used by the test scripts.
408 - The parallel-tests harness generates now, in addition the '.log' files
409 holding the output produced by the test scripts, a new set of '.trs'
410 files, holding "metadata" derived by the execution of the test scripts;
411 among such metadata are the outcomes of the test cases run by a script.
413 - Initial and still experimental support for the TAP test protocol is
416 * Changes to Yacc and Lex support:
418 - C source and header files derived from non-distributed Yacc and/or
419 Lex sources are now removed by a simple "make clean" (while they were
420 previously removed only by "make maintainer-clean").
422 - Slightly backward-incompatible change, relevant only for use of Yacc
423 with C++: the extensions of the header files produced by the Yacc
424 rules are now modelled after the extension of the corresponding
425 sources. For example, yacc files named "foo.y++" and "bar.yy" will
426 produce header files named "foo.h++" and "bar.hh" respectively, where
427 they would have previously produced header files named simply "foo.h"
428 and "bar.h". This change offers better compatibility with 'bison -o'.
430 * Miscellaneous changes:
432 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
433 rather than 1, if the vala compiler found is too old.
435 - The build system of Automake itself now avoids the use of make
436 recursion as much as possible.
438 - Automake now prefers to quote 'like this' or "like this", rather
439 than `like this', in diagnostic message and generated Makefiles,
440 to accommodate the new GNU Coding Standards recommendations.
442 - Automake has a new option '--print-libdir' that prints the path of the
443 directory containing the Automake-provided scripts and data files.
445 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
447 - The rules to create pdf, dvi and ps output from Texinfo files now
448 works better with modern 'texi2dvi' script, by explicitly passing
449 it the '--clean' option to ensure stray auxiliary files are not
450 left to clutter the build directory.
452 - Automake can now generate silenced rules for texinfo outputs.
454 - Some auxiliary files that are automatically distributed by Automake
455 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
456 C sources) might now be listed in the DIST_COMMON variable in many
457 Makefile.in files, rather than in the top-level one.
459 - Messages of types warning or error from 'automake' and 'aclocal'
460 are now prefixed with the respective type, and presence of -Werror
463 - Automake's early configure-time sanity check now tries to avoid
464 sleeping for a second, which slowed down cached configure runs
465 noticeably. In that case, it will check back at the end of the
466 configure script to ensure that at least one second has passed, to
467 avoid time stamp issues with makefile rules rerunning autotools
470 - The warnings in the category 'extra-portability' are now enabled by
471 '-Wall'. In previous versions, one has to use '-Wextra-portability'
476 - Various minor bugfixes for recent or long-standing bugs.
478 * Bugs introduced by 1.11:
480 - The AM_COND_IF macro also works if the shell expression for the
481 conditional is no longer valid for the condition.
483 - The automake-provided parallel testsuite harness does not fail anymore
484 with BSD make used in parallel mode when there are test scripts in a
485 subdirectory, like in:
487 TESTS = sub/foo.test sub/bar.test
489 * Long-standing bugs:
491 - Automake's own build system finally have a real "installcheck" target.
493 - Vala-related cleanup rules are now more complete, and work better in
496 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
497 now automatically distributed also if the directory of the auxiliary
498 files coincides with the top-level directory.
500 - Automake now detects the presence of the '-d' flag in the various
501 '*YFLAGS' variables even when their definitions involve indirections
502 through other variables, such as in:
504 AM_YFLAGS = $(foo_opts)
506 - Automake now complains if a '*YFLAGS' variable has any conditional
507 content, not only a conditional definition.
509 - Explicit enabling and/or disabling of Automake warning categories
510 through the '-W...' options now always takes precedence over the
511 implicit warning level implied by Automake strictness (foreign, gnu
512 or gnits), regardless of the order in which such strictness and
513 warning flags appear. For example, a setting like:
514 AUTOMAKE_OPTIONS = -Wall --foreign
515 will cause the warnings in category 'portability' to be enabled, even
516 if those warnings are by default disabled in 'foreign' strictness.
518 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
520 Bugs fixed in 1.11.5:
522 * Bugs introduced by 1.11.3:
524 - Vala files with '.vapi' extension are now recognized and handled
525 correctly again. See automake bug#11222.
527 - Vala support work again for projects that contain some program
528 built from '.vala' (and possibly '.c') sources and some other
529 program built from '.c' sources *only*. See automake bug#11229.
531 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
535 * Miscellaneous changes:
537 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
538 symbol index) modifiers as well as the "s" action, as the symbol index
539 is created unconditionally by Microsoft lib. Also, the "q" (quick)
540 action is now a synonym for "r" (replace). Also, the script has been
541 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
543 - When the 'compile' script is used to wrap MSVC, it now accepts an
544 optional space between the -I, -L and -l options and their respective
545 arguments, for better POSIX compliance.
547 - There is an initial, experimental support for automatic dependency
548 tracking with tcc (the Tiny C Compiler). Its associated depmode is
549 currently recognized as "icc" (but this and other details are likely
550 to change in future versions).
552 - Automatic dependency tracking now works also with the IBM XL C/C++
553 compilers, thanks to the new new depmode 'xlc'.
555 Bugs fixed in 1.11.4:
557 * Bugs introduced by 1.11.2:
559 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
560 don't cause spurious failures upon "make install" anymore.
562 - The user can now instruct the 'uninstall-info' rule not to update
563 the '${infodir}/dir' file by exporting the environment variable
564 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
565 with how the 'install-info' rule operates since automake 1.11.2.
567 * Long-standing bugs:
569 - It is now possible for a foo_SOURCES variable to hold Vala sources
570 together with C header files, as well as with sources and headers for
571 other supported languages (e.g., C++). Previously, only mixing C and
572 Vala sources was supported.
574 - If "aclocal --install" is used, and the first directory specified with
575 '-I' is non-existent, aclocal will now create it before trying to copy
578 - An empty declaration of a "foo_PRIMARY" don't cause anymore the
579 generated install rules to create an empty $(foodir) directory;
580 for example, if Makefile.am contains something like:
584 pkglibexec_SCRIPTS += bar.sh
587 the $(pkglibexec) directory will not be created upon "make install".
589 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
593 * Miscellaneous changes:
595 - Automake's own build system is more silent by default, making use of
596 the 'silent-rules' option.
598 - The master copy of the `gnupload' script is now maintained in gnulib,
601 - The `missing' script doesn't try to wrap calls to `tar' anymore.
603 - "make dist" doesn't wrap `tar' invocations with the `missing' script
604 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
605 shouldn't be using BTW ;-) does not invoke the missing script anymore
606 to wrap tar, but simply invokes the `tar' program itself.
608 - "make dist" can now create lzip-compressed tarballs.
610 - In the Automake info documentation, the Top node and the nodes about
611 the invocation of the automake and aclocal programs have been renamed;
612 now, calling "info automake" will open the Top node, while calling
613 "info automake-invocation" and "info aclocal-invocation" will access
614 the nodes about the invocation of respectively automake and aclocal.
616 - Automake is now distributed as a gzip-compressed and an xz-compressed
617 tarball. Previously, bzip2 was used instead of xz.
619 - The last relics of Python 1.5 support have been removed from the
620 AM_PATH_PYTHON macro.
622 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
623 and adds them to the normal list of dependencies, but without
624 overwriting the foo_DEPENDENCIES variable, which is normally computed
627 Bugs fixed in 1.11.3:
629 * Bugs introduced by 1.11.2:
631 - Automake now correctly recognizes the prefix/primary combination
632 `pkglibexec_SCRIPTS' as valid.
634 - The parallel-tests harness doesn't trip anymore on sed implementations
635 with stricter limits on the length of input lines (problem seen at
638 * Long-standing bugs:
640 - The "deleted header file problem" for *.am files is avoided by stub
641 rules. This allows `make' to trigger a rerun of `automake' also if
642 some previously needed `.am' file has been removed.
644 - The `silent-rules' option now generates working makefiles even
645 for the uncommon `make' implementations that do not support the
646 nested-variables extension to POSIX 2008. For such `make'
647 implementations, whether a build is silent is determined at
648 configure time, and cannot be overridden at make time with
649 `make V=0' or `make V=1'.
651 - Vala support now works better in VPATH setups.
653 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
657 * Changes to aclocal:
659 - The `--acdir' option is deprecated. Now you should use the new options
660 `--automake-acdir' and `--system-acdir' instead.
662 - The `ACLOCAL_PATH' environment variable is now interpreted as a
663 colon-separated list of additional directories to search after the
664 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
665 and before the system acdir (by default ${prefix}/share/aclocal).
667 * Miscellaneous changes:
669 - The Automake support for automatic de-ANSI-fication has been
670 deprecated. It will probably be removed in the next major Automake
673 - The `lzma' compression scheme and associated automake option `dist-lzma'
674 is obsoleted by `xz' and `dist-xz' due to upstream changes.
676 - You may adjust the compression options used in dist-xz and dist-bzip2.
677 The default is now merely -e for xz, but still -9 for bzip; you may
678 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
679 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
681 - The `compile' script now converts some options for MSVC for a better
682 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
684 - The py-compile script now accepts empty arguments passed to the options
685 `--destdir' and `--basedir', and complains about unrecognized options.
686 Moreover, a non-option argument or a special `--' argument terminates
689 - A developer that needs to pass specific flags to configure at "make
690 distcheck" time can now, and indeed is advised to, do so by defining
691 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
692 instead of the old DISTCHECK_CONFIGURE_FLAGS.
693 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
694 user; still, the old Makefile.am files that used to define it will
695 still continue to work as before.
697 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
698 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
699 This new macro is required for LIBRARIES and LTLIBRARIES when automake
700 is run with -Wextra-portability and -Werror.
702 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
703 file generated by automake-provided rules by defining the special make
704 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
706 - The `install-info' rule can now be instructed not to create/update
707 the `${infodir}/dir' file, by exporting the new environment variable
708 `AM_UPDATE_INFO_DIR' to the value "no".
710 Bugs fixed in 1.11.2:
712 * Bugs introduced by 1.11:
714 - The parallel-tests driver no longer produces erroneous results with
715 Tru64/OSF 5.1 sh upon unreadable log files.
717 - The `parallel-tests' test driver does not report spurious successes
718 when used with concurrent FreeBSD make (e.g., "make check -j3").
720 - When the parallel-tests driver is in use, automake now explicitly
721 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
722 instead of issuing confusing and apparently unrelated error messages
723 (e.g., "non-POSIX variable name", "bad characters in variable name",
724 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
725 silently producing broken `Makefile.in' files.
727 - The `silent-rules' option now truly silences all compile rules, even
728 when dependency tracking is disabled. Also, when `silent-rules' is
729 not used, `make' output no longer contains spurious backslash-only
730 lines, thus once again matching what Automake did before 1.11.
732 - The AM_COND_IF macro also works if the shell expression for the
733 conditional is no longer valid for the condition.
735 * Long-standing bugs:
737 - The order of Yacc and Lex flags is fixed to be consistent with other
738 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
739 $(LFLAGS), so that the user variables override the developer variables.
741 - "make distcheck" now correctly complains also when "make uninstall"
742 leaves one and only one file installed in $(prefix).
744 - A "make uninstall" issued before a "make install", or after a mere
745 "make install-data" or a mere "make install-exec" does not spuriously
748 - Automake now warns about more primary/directory invalid combinations,
749 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
751 - Rules generated by Automake now try harder to not change any files when
752 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
753 Yacc source files and the rule to update config.h.
755 - Several scripts and the parallel-tests testsuite driver now exit with
756 the right exit status upon receiving a signal.
758 - A per-Makefile.am setting of -Werror does not erroneously carry over
759 to the handling of other Makefile.am files.
761 - The code for automatic dependency tracking works around a Solaris
762 make bug triggered by sources containing repeated slashes when the
763 `subdir-objects' option was used.
765 - The makedepend and hp depmodes now work better with VPATH builds.
767 - Java sources specified with check_JAVA are no longer compiled for
768 "make all", but only for "make check".
770 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
771 and error out if `javadir' is undefined, instead of silently producing
772 a broken Makefile.in.
774 - aclocal and automake now honour the configure-time definitions of
775 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
777 - The `install-info' recipe no longer tries to guess whether the
778 `install-info' program is from Debian or from GNU, and adaptively
779 change its behaviour; this has proven to be frail and easy to
782 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
784 Bugs fixed in 1.11.1:
786 - Lots of minor bugfixes.
788 * Bugs introduced by 1.11:
790 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
791 trailing white space in the test list (`TESTS = foo $(EMPTY)').
793 * Long standing bugs:
795 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
796 even if the `--prefix' argument pointed outside of a system directory.
797 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
798 `get_python_lib' function if it points outside the configured prefix,
799 unless the `--prefix' argument was either `/usr' or below `/System'.
801 - The testsuite does not try to change the mode of `ltmain.sh' files from
802 a Libtool installation (symlinked to test directories) any more.
804 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
805 tools are preferred in a cross-compile setup.
807 - The distribution is tarred up with mode 755 now by the `dist*' targets.
808 This fixes a race condition where untrusted users could modify files
809 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
810 build directory was world-searchable. This is CVE-2009-4029.
812 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
816 * Version requirements:
818 - Autoconf 2.62 or greater is required.
820 * Changes to aclocal:
822 - The autoconf version check implemented by aclocal in aclocal.m4
823 (and new in Automake 1.10) is degraded to a warning. This helps
824 in the common case where the Autoconf versions used are compatible.
826 * Changes to automake:
828 - The automake program can run multiple threads for creating most
829 Makefile.in files concurrently, if at least Perl 5.7.2 is available
830 with interpreter-based threads enabled. Set the environment variable
831 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
832 enable this experimental feature.
834 * Changes to Libtool support:
836 - Libtool generic flags are now passed to the install and uninstall
839 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
840 config.lt is removed correctly now.
844 - subdir-object mode works now with Fortran (F77, FC, preprocessed
845 Fortran, and Ratfor).
847 - For files with extension .f90, .f95, .f03, or .f08, the flag
848 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
850 - Files with extension .sx are also treated as preprocessed assembler.
852 - The default source file extension (.c) can be overridden with
853 AM_DEFAULT_SOURCE_EXT now.
855 - Python 3.0 is supported now, Python releases prior to 2.0 are no
858 - AM_PATH_PYTHON honors python's idea about the site directory.
860 - There is initial support for the Vala programming language, when using
863 * Miscellaneous changes:
865 - Automake development is done in a git repository on Savannah now, see
867 http://git.sv.gnu.org/gitweb/?p=automake.git
869 A read-only CVS mirror is provided at
871 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
872 checkout -d automake HEAD
874 - "make dist" can now create xz-compressed tarballs,
875 as well as (deprecated?) lzma-compressed tarballs.
877 - `automake --add-missing' will by default install the GPLv3 file as
878 COPYING if it is missing. It will also warn that the license file
879 should be added to source control. Note that Automake will never
880 overwrite an existing COPYING file, even when the `--force-missing'
883 - The manual is now distributed under the terms of the GNU FDL 1.3.
885 - Automake ships and installs man pages for automake and aclocal now.
887 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
889 - install-sh supports -C, which does not update the installed file
890 (and its time stamps) if the contents did not change.
892 - The `gnupload' script has been revamped.
894 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
896 - The targets `install' and `uninstall' are more efficient now, in that
897 for example multiple files from one Automake variable such as
898 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
899 invocation if they do not have to be renamed.
901 Both install and uninstall may sometimes enter (`cd' into) the target
902 installation directory now, when no build-local scripts are used.
904 Both install and uninstall do not fail anymore but do nothing if an
905 installation directory variable like `bindir' is set to the empty string.
907 For built-in rules, `make install' now fails reliably if installation
908 of a file failed. Conversely, `make uninstall' even succeeds when
909 issued multiple times.
911 These changes may need some adjustments from users: For example,
912 some `install' programs refuse to install multiple copies of the
913 same file in one invocation, so you may need to remove duplicate
914 entries from file lists.
916 Also, within one set of files, say, nobase_data_DATA, the order of
917 installation may be changed, or even unstable among different hosts,
918 due to the use of associative arrays in awk. The increased use of
919 awk matches a similar move in Autoconf to provide for better scaling.
921 Further, most undocumented per-rule install command variables such as
922 binSCRIPT_INSTALL have been removed because they are not needed any
923 more. Packages which use them should be using the appropriate one of
924 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
925 counterpart, depending on the type of files and the need for automatic
926 target directory creation.
928 - The "deleted header file problem" for *.m4 files is avoided by
929 stub rules. This allows `make' to trigger a rerun of `aclocal'
930 also if some previously needed macro file has been removed.
932 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
933 an otherwise up to date tree.
935 - The `color-tests' option causes colored test result output on terminals.
937 - The `parallel-tests' option enables a new test driver that allows for
938 parallel test execution, inter-test dependencies, lazy test execution
939 for unit-testing, re-testing only failed tests, and formatted result output
940 as RST (reStructuredText) and HTML. Enabling this option may require some
941 changes to your test suite setup; see the manual for details.
943 - The `silent-rules' option enables Linux kernel-style silent build output.
944 This option requires the widely supported but non-POSIX `make' feature
945 of recursive variable expansion, so do not use it if your package needs
946 to build with `make' implementations that do not support it.
948 To enable less verbose build output, the developer has to use the Automake
949 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
950 macro. The user may then set the default verbosity by passing the
951 `--enable-silent-rules' option to `configure'. At `make' run time, this
952 default may be overridden using `make V=0' for less verbose, and `make V=1'
953 for backward-compatible verbose output.
955 - New prefix `notrans_' for manpages which should not be transformed
956 by --program-transform.
958 - New macro AM_COND_IF for conditional evaluation and conditional
961 - For AC_CONFIG_LINKS, if source and destination are equal, do not
962 remove the file in a non-VPATH build. Such setups work with Autoconf
965 - AM_MAINTAINER_MODE now allows for an optional argument specifying
968 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
969 useful especially for multi-line values.
971 - Automake's early configure-time sanity check now diagnoses an
972 unsafe absolute source directory name and makes configure fail.
974 - The Automake macros and rules cope better with whitespace in the
975 current directory name, as long as the relative path to `configure'
976 does not contain whitespace. To this end, the values of `$(MISSING)'
977 and `$(install_sh)' may contain suitable quoting, and their expansion
978 might need `eval'uation if used outside of a makefile. These
979 undocumented variables may be used in several documented macros such
980 as $(AUTOCONF) or $(MAKEINFO).
984 * Long-standing bugs:
986 - Fix aix dependency tracking for libtool objects.
988 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
989 unnecessary use of the `compile' script.
991 - For nobase_*_LTLIBRARIES with nonempty directory components, the
992 correct `-rpath' argument is used now.
994 - `config.status --file=Makefile depfiles' now also works with the
995 extra quoting used internally by Autoconf 2.62 and newer
996 (it used to work only without the `--file=' bit).
998 - The `missing' script works better with versioned tool names.
1000 - Semantics for `missing help2man' have been revamped:
1002 Previously, if `help2man' was not present, `missing help2man' would have
1003 the following semantics: if some man page was out of date but present, then
1004 a warning would be printed, but the exit status was 0. If the man page was
1005 not present at all, then `missing' would create a replacement man page
1006 containing an error message, and exit with a status of 2. This does not play
1007 well with `make': the next run will see this particular man page as being up
1008 to date, and will only error out on the next generated man page, if any;
1009 repeat until all pages are done. This was not desirable.
1011 These are the new semantics: if some man page is not present, and help2man
1012 is not either, then `missing' will warn and generate the replacement page
1013 containing the error message, but exit successfully. However, `make dist'
1014 will ensure that no such bogus man pages are packaged into a tarball.
1016 - Targets provided by automake behave better with `make -n', in that they
1017 take care not to create files.
1019 - `config.status Makefile... depfiles' works fine again in the presence of
1020 disabled dependency tracking.
1022 - The default no-op recursive rules for these targets also work with BSD make
1023 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
1025 - `make distcheck' works also when both a directory and some file below it
1026 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
1028 - Texinfo dvi, ps, pdf, and html output files are not removed upon
1029 `make mostlyclean' any more; only the LaTeX by-products are.
1031 - Renamed objects also work with the `subdir-objects' option and
1032 source file languages which Automake does not know itself.
1034 - `automake' now correctly complains about variable assignments which are
1035 preceded by a comment, extend over multiple lines with backslash-escaped
1036 newlines, and end in a comment sign. Previous versions would silently
1037 and wrongly ignore such assignments completely.
1039 * Bugs introduced by 1.10:
1041 - Fix output of dummy dependency files in presence of post-processed
1042 Makefile.in's again, but also cope with long lines.
1044 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
1045 that have been declared as programs in the same Makefile.
1046 This is for consistency with the analogous change to TESTS in 1.10.
1048 - Fix order of standard includes to again be `-I. -I$(srcdir)',
1049 followed by directories containing config headers.
1051 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1055 * Version requirements:
1057 - Autoconf 2.60 or greater is required.
1059 - Perl 5.6 or greater is required.
1061 * Changes to aclocal:
1063 - aclocal now also supports -Wmumble and -Wno-mumble options.
1065 - `dirlist' entries (for the aclocal search path) may use shell
1066 wildcards such as `*', `?', or `[...]'.
1068 - aclocal supports an --install option that will cause system-wide
1069 third-party macros to be installed in the local directory
1070 specified with the first -I flag. This option also uses #serial
1071 lines in M4 files to upgrade local macros.
1073 The new aclocal options --dry-run and --diff help to review changes
1074 before they are installed.
1076 - aclocal now outputs an autoconf version check in aclocal.m4 in
1077 projects using automake.
1079 For a few years, automake and aclocal have been calling autoconf
1080 (or its underlying engine autom4te) to accurately retrieve the
1081 data they need from configure.ac and its siblings. Doing so can
1082 only work if all autotools use the same version of autoconf. For
1083 instance a Makefile.in generated by automake for one version of
1084 autoconf may stop working if configure is regenerated with another
1085 version of autoconf, and vice versa.
1087 This new version check ensures that the whole build system has
1088 been generated using the same autoconf version.
1090 * Support for new Autoconf macros:
1092 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
1094 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
1095 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
1096 in different directories. However, only one instance of such a
1097 library objects directory is supported.
1099 * Change to Libtool support:
1101 - Libtool generic flags (those that go before the --mode=MODE option)
1102 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
1104 * Yacc and Lex changes:
1106 - The rebuild rules for distributed Yacc and Lex output will avoid
1107 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
1110 - ylwrap is now always used for lex and yacc source files,
1111 regardless of whether there is more than one source per directory.
1113 * Languages changes:
1115 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
1116 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
1117 tracking, unlike non-preprocessed assembler (*.s).
1119 - subdir-object mode works now with Assembler. Automake assumes
1120 that the compiler understands `-c -o'.
1122 - Preprocessed assembler (*.S) compilation now also honors
1123 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
1125 - Improved support for Objective C:
1126 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
1127 - A new section of the manual documents the support.
1129 - New support for Unified Parallel C:
1130 - AM_PROG_UPC looks for a UPC compiler.
1131 - A new section of the manual documents the support.
1133 - Per-target flags are now correctly handled in link rules.
1135 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
1136 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
1137 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
1138 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
1140 The fix for compiler flags (i.e., using maude_CFLAGS instead of
1141 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
1142 is expected to work (and actually works during compilation).
1144 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
1145 "in addition to" breaks backward compatibility with older versions.
1146 If your package used both variables, as in
1148 AM_LDFLAGS = common flags
1149 bin_PROGRAMS = a b c
1150 a_LDFLAGS = more flags
1153 and assumed *_LDFLAGS would sum up, you should rewrite it as
1155 AM_LDFLAGS = common flags
1156 bin_PROGRAMS = a b c
1157 a_LDFLAGS = $(AM_LDFLAGS) more flags
1160 This new behavior of *_LDFLAGS is more coherent with other
1161 per-target variables, and the way *_LDFLAGS variables were
1162 considered internally.
1164 * New installation targets:
1166 - New targets mandated by GNU Coding Standards:
1171 By default they will only install Texinfo manuals.
1172 You can customize them with *-local variants:
1178 - The undocumented recursive target `uninstall-info' no longer exists.
1179 (`uninstall' is in charge of removing all possible documentation
1180 flavors, including optional formats such as dvi, ps, or info even
1181 when `no-installinfo' is used.)
1183 * Miscellaneous changes:
1185 - Automake no longer complains if input files for AC_CONFIG_FILES
1186 are specified using shell variables.
1188 - clean, distribution, or rebuild rules are normally disabled for
1189 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
1190 AC_CONFIG_LINK specified using shell variables. However, if these
1191 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
1192 be able to output rules anyway.
1193 (See the Automake documentation for AC_CONFIG_FILES.)
1195 - $(EXEEXT) is automatically appended to filenames of TESTS
1196 that have been declared as programs in the same Makefile.
1197 This is mostly useful when some check_PROGRAMS are listed in TESTS.
1199 - `-Wportability' has finally been turned on by default for `gnu' and
1200 `gnits' strictness. This means, automake will complain about %-rules
1201 or $(GNU Make functions) unless you switch to `foreign' strictness or
1202 use `-Wno-portability'.
1204 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
1205 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
1206 $(mkdir_p) variable is still defined (to the same value as
1207 $(MKDIR_P)) but should be considered obsolete. If you are using
1208 $(mkdir_p) in some of your rules, please plan to update them to
1209 $(MKDIR_P) at some point.
1211 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
1212 They still work in this release, but may be withdrawn in a future one.
1214 - Inline compilation rules for gcc3-style dependency tracking are
1217 - Automake installs a "Hello World!" example package in $(docdir).
1218 This example is used throughout the new "Autotools Introduction"
1219 chapter of the manual.
1221 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1225 * Makefile.in bloat reduction:
1227 - Inference rules are used to compile sources in subdirectories when
1228 the `subdir-objects' option is used and no per-target flags are
1229 used. This should reduce the size of some projects a lot, because
1230 Automake used to output an explicit rule for each such object in
1233 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1234 object that must be built with explicit rules. It just outputs
1235 the rules required to build the kind of object considered: either
1236 the two .o and .obj rules for usual objects, or the .lo rule for
1239 * Change to Libtool support:
1241 - Libtool tags are used with libtool versions that support them.
1242 (I.e., with Libtool 1.5 or greater.)
1244 - Automake is now able to handle setups where a libtool library is
1245 conditionally installed in different directories, as in
1248 lib_LTLIBRARIES = liba.la
1250 pkglib_LTLIBRARIES = liba.la
1252 liba_la_SOURCES = ...
1254 * Changes to aclocal:
1256 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1257 really evaluated, before it decides to include them in aclocal.m4.
1258 This solves nasty problems with conditional redefinitions of
1259 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1260 *.m4 files to be included in any project using these macros.
1261 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1262 most famous instance of this bug.)
1264 - Do not complain about missing conditionally AC_REQUIREd macros
1265 that are not actually used. In 1.8.x aclocal would correctly
1266 determine which of these macros were really needed (and include
1267 only these in the package); unfortunately it would also require
1268 all of them to be present in order to run. This created
1269 situations were aclocal would not work on a tarball distributing
1270 all the macros it uses. For instance running aclocal on a project
1271 containing only the subset of the Gettext macros in use by the
1272 project did not work, because gettext conditionally requires other
1275 * Portability improvements:
1277 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1278 tar-pax. The new option filename-length-max=99 helps diagnosing
1279 filenames that are too long for tar-v7. (PR/414)
1281 - Variables aumented with `+=' are now automatically flattened (i.e.,
1282 trailing backslashes removed) and then wrapped around 80 colummns
1283 (adding trailing backslashes). In previous versions, a long series
1289 would result in a single-line definition of VAR that could possibly
1290 exceed the maximum line length of some make implementations.
1292 Non-augmented variables are still output as they are defined in
1297 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1298 Works the same as the old Fortran 77 implementation; just replace
1299 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1300 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1302 - Support for conditional _LISP.
1304 - Support for conditional -hook and -local rules (PR/428).
1306 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1308 - Automake will not write any Makefile.ins after the first error it
1309 encounters. The previous Makefile.ins (if any) will be left in
1310 place. (Warnings will not prevent output, but remember they can
1311 be turned into errors with -Werror.)
1313 - The restriction that SUBDIRS must contain direct children is gone.
1316 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1317 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1319 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1321 Bugs fixed in 1.8.5:
1323 * Long-standing bugs:
1325 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1326 so that `make distclean' and `make maintainer-clean' can work.
1328 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1330 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1332 - Polish diagnostic when no input file is found.
1334 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1336 Bugs fixed in 1.8.4:
1338 * Long-standing bugs:
1340 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1341 overridden by the user.
1343 - Honor PATH_SEPARATOR in various places of the Automake package, for
1346 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1349 - Fix install-sh so it can install the `mv' binary... using `mv'.
1351 - Fix tru64 dependency tracking for libtool objects.
1353 - Work around Exuberant Ctags when creating a TAGS files in a directory
1354 without files to scan but with subdirectories to include.
1356 * Bugs introduced by 1.8:
1358 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1359 not defined in the same conditions as the _LDADD that uses it.
1361 - Do not warn when JAVAROOT is overridden, this is legitimate.
1363 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1365 Bugs fixed in 1.8.3:
1367 * Long-standing bugs:
1369 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1370 or any of the other *dir variables contain a space.
1372 Please note that Automake does not and cannot support spaces in
1373 filenames that are involved during the build. This change affects
1374 only installation paths, so that `make install' does not bomb out
1375 in packages configured with
1376 ./configure --prefix '/c/Program Files'
1378 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1379 POSIXLY_CORRECT is set.
1381 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1382 since Autoconf 2.54, which defines LIBOBJS itself.
1384 - Fix a potential (but unlikely) race condition in parallel elisp
1385 builds. (Introduced in 1.7.3.)
1387 - Do not assume that users override _DEPENDENCIES in all conditions
1388 where Automake will try to define them.
1390 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1391 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1394 This fix also affects the $(mkdir_p) variable defined since
1395 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1396 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1398 - Secure temporary directory creation in `make distcheck'. (PR/413)
1400 - Do not generate two build rules for `parser.h' when the
1401 parser appears in two different conditionals.
1403 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1404 checking. Usually ./configure will not pick this shell; so this
1405 fix only helps cases where the shell is forced to /bin/sh.
1407 * Bugs introduced by 1.8:
1409 - In some situations (hand-written `m4_include's), aclocal would
1410 call the `File::Spec->rel2abs' method, which was only introduced
1411 in Perl 5.6. This new version reestablish support Perl 5.005.
1413 It is likely that the next major Automake releases will require at
1414 least Perl 5.6. Consider upgrading your development environment
1415 if you are still using the five-year-old Perl 5.005.
1417 - Automake would sometimes fail to define rules for targets listed
1418 in variables defined in multiple conditions. For instance on
1424 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1425 `b.$(OBJEXT): b.c' rule.
1427 * New sections in manual:
1429 - Third-Party Makefiles: how to interface third party Makefiles.
1430 - Upgrading: upgrading packages to newer Automake versions.
1431 - Multiple Outputs: handling tools that produce many outputs.
1433 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1437 * A (well known) portability bug slipped in the changes made to
1438 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1439 install anything on Tru64.
1441 * Fix install rules for conditionally built python files. (This never
1444 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1448 * Bugs introduced by 1.8:
1450 - Fix Config.pm import error with old Perl versions (at least
1451 5.005_03). One symptom is that aclocal could not find its macro
1454 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1455 created by `make install' are always world readable, even if the
1456 installer happens to have an overly restrictive umask (e.g. 077).
1457 This was a mistake and has been reverted. There are at least two
1458 reasons why we must not use `-m 0755':
1459 - it causes special bits like SGID to be ignored,
1460 - it may be too restrictive (some setups expect 775 directories).
1462 - Fix aclocal to honor definitions located in files which have been
1463 m4_included manually. aclocal 1.8 had been updated to check
1464 m4_included files for new requirements, but forgot that these
1465 m4_included files can also provide new definitions.
1467 Note that if you have such a setup, we recommend you get rid of
1468 it. In the past, there was a reason to m4_include files manually:
1469 aclocal used to duplicate entire M4 files into aclocal.m4, even
1470 files that were distributed. Some packages were therefore
1471 m4_including the distributed file directly, and playing some
1472 tricks to ensure aclocal would not copy that file to aclocal.m4,
1473 in order to limit the amount of duplication. Since aclocal 1.8.x
1474 will precisely output m4_includes for local M4 files, we recommend
1475 that you clean up your setup, removing all manual m4_includes and
1476 letting aclocal output them.
1478 - Output detailed menus in the Info version if the Automake manual,
1479 so that Emacs can locate the indexes.
1481 - configure.ac and configure were listed twice in DIST_COMMON (an
1482 internal variable where Automake lists configury files to
1483 distribute). This was harmless, but unaesthetic.
1485 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1486 This was an issue only in the Automake package itself, not in
1489 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1490 DEST:SRC. This was wrong, as some packages do
1491 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1494 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1495 argument. This caused two kinds of failures:
1496 - Rules installing data in a conditionally defined directory
1497 failed when that directory was undefined. In this case no
1498 argument was supplied.
1499 - `make installdirs' failed, because several directories were
1500 passed to $(mkdir_p). This was an issue only on platform
1501 were $(mkdir_p) is implemented with `install-sh -d'.
1502 $(mkdir_p) as been changed to accept 0 or more arguments, as
1505 * Long-standing bugs:
1507 - Fix an unexpected diagnostic occurring when users attempt
1508 to override some internal variables that Automake appends to.
1510 - aclocal now scans configure.ac for macro definitions (PR/319).
1512 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1513 distributes files which are outside itself (this usually occurs
1514 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1515 from a parent package), then `make distcheck' fails due to an
1516 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1517 (tests/subpkg2.test failure)
1519 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1520 In a VPATH-build configuration, `make install' would install
1521 nobase_ files to wrong locations.
1523 - Fix a Perl `uninitialized value' diagnostic occurring when
1524 automake complains that a Texinfo file does not have a
1525 @setfilename statement.
1527 - Erase config.status.lineno during `make distclean'. This file
1528 can be created by config.status. Automake already knew about
1529 configure.lineno, but forgot config.status.lineno.
1531 - Distribute all files, even those which are built and installed
1532 conditionally. This change affects files listed in conditionally
1533 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1534 as well as those listed in conditionally defined dist_*_DATA,
1535 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1537 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1538 doesn't conform to POSIX.
1540 - Normalize help strings for configure variables and options added
1545 - Check for python2.4 in AM_PATH_PYTHON.
1547 * Spurious failures in test suite:
1549 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1550 tests/ltconv.test: fix failures with CVS Libtool.
1551 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1552 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1553 fix failures with old Texinfo versions.
1555 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1561 - The NEWS file is more verbose.
1565 - Autoconf 2.58 or greater is required.
1569 - Default source file names in the absence of a _SOURCES declaration
1570 are made by removing any target extension before appending `.c', so
1571 to make the libtool module `foo.la' from `foo.c', you only need to
1574 lib_LTLIBRARIES = foo.la
1575 foo_la_LDFLAGS = -module
1577 For backward compatibility, foo_la.c will be used instead of
1578 foo.c if this file exists or is the explicit target of a rule.
1579 However -Wobsolete will warn about this deprecated naming.
1581 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1582 of being hard-coded in each $(AR) invocation, so they can be
1583 substituted from configure.ac. This has been requested by people
1584 dealing with non-POSIX ar implementations.
1586 - New warning option: -Woverride. This will warn about any user
1587 target or variable definitions which override Automake
1590 - Texinfo rules back up and restore info files when makeinfo fails.
1592 - Texinfo rules now support the `html' target.
1593 Running this requires Texinfo 4.0 or greater.
1595 `html' is a new recursive target, so if your package mixes
1596 hand-crafted `Makefile.in's with Automake-generated
1597 `Makefile.in's, you should adjust the former to support (or
1598 ignore) this target so that `make html' recurses successfully. If
1599 you had a custom `html' rule in your `Makefile.am', it's better to
1600 rename it as `html-local', otherwise your rule will override
1601 Automake's new rule (you can check that by running `automake
1602 -Woverride') and that will stop the recursion to subdirectories.
1604 Last but not least, this `html' rule is declared PHONY, even when
1605 overridden. Fortunately, it appears that few packages use a
1606 non-PHONY `html' rule.
1608 - Any file which is m4_included from configure.ac will appear as a
1609 configure and Makefile.in dependency, and will be automatically
1612 - The rules for rebuilding Makefiles and Makefile.ins will now
1613 rebuild all Makefiles and all Makefile.ins at once when one of
1614 configure's dependencies has changed. This is considerably faster
1615 than previous implementations, where config.status and automake
1616 were run separately in each directory (this still happens when you
1617 change a Makefile.am locally, without touching configure.ac or
1618 friends). Doing this also solves a longstanding issue: these
1619 rebuild rules failed to work when adding new directories to the
1620 tree, forcing you to run automake manually.
1622 - For similar reasons, the rules to rebuild configure,
1623 config.status, and aclocal.m4 are now defined in all directories.
1624 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1625 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1626 should better define them in all directories. This is easily done
1627 using an AC_SUBST (make sure you prefix these dependencies with
1628 $(top_srcdir) since this variable will appear at different
1629 levels of the build tree).
1631 - aclocal will now use `m4_include' instead of copying local m4
1632 files into aclocal.m4. (Local m4 files are those you ship with
1633 your project, other files will be copied as usual.)
1635 Because m4_included files are automatically distributed, it means
1636 for most projects there is no point in EXTRA_DISTing the list of
1637 m4 files which are used. (You can probably get rid of
1638 m4/Makefile.am if you had one.)
1640 - aclocal will avoid touching aclocal.m4 when possible, so that
1641 Autom4te's cache isn't needlessly invalidated. This behavior can
1642 be switched off with the new `--force' option.
1644 - aclocal now uses Autoconf's --trace to detect macros which are
1645 actually used and will no longer include unused macros simply
1646 because they where mentioned. This was often the case for macros
1647 called conditionally.
1649 - New options no-dist and no-dist-gzip.
1651 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1652 py-compile, and ylwrap, now all understand --version and --help.
1654 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1655 links as part of the distclean target and including source files in
1658 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1659 argument. The latter can be used to override the default behavior
1660 (which is to abort).
1662 - Automake will exit with $? = 63 on version mismatch. (So does
1663 Autoconf 2.58) missing knows this, and in this case it will
1664 emulate the tools as if they were absent. Because older versions
1665 of Automake and Autoconf did not use this exit code, this change
1666 will only be useful in projects generated with future versions of
1669 - When using AC_CONFIG_FILES with multiple input files, Automake
1670 generates the first ".in" input file for which a ".am" exists.
1671 (Former versions would try to use only the first input file.)
1673 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1674 idiom to disable byte-compilation of lisp_LISP files, it is
1675 recommended that you switch to using lisp_DATA. Note that
1676 this is not strictly equivalent: lisp_DATA will install elisp
1677 files even if emacs is not installed, while *_LISP do not
1678 install anything unless emacs is found.
1680 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1681 available. This selection is achieved through the Makefile
1682 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1683 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1684 `$(install_sh) -m 0755 -d'.
1688 - Because `mkdir -p' is available on most platforms, and we can use
1689 `install-sh -d' when it is not, the use of the mkinstalldirs
1690 script is being phased out. `automake --add-missing' no longer
1691 installs it, and if you remove mkinstalldirs from your package,
1692 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1694 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1695 gettextize and autopoint will install it when needed. Automake
1696 will continue to define the $(mkinstalldirs) and to distribute
1697 mkinstalldirs when this script is in the source tree.
1699 - AM_PROG_CC_STDC is now empty. The content of this macro was
1700 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1701 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1702 renaming should be safe, even if you have to support several,
1703 versions of Automake, because AC_PROG_CC defines this variable
1704 since Autoconf 2.54.)
1706 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1707 variable to override the aclocal.m4 dependencies computed
1708 (inaccurately) by older versions of Automake. Because Automake
1709 now tracks configure's m4 dependencies accurately (see m4_include
1710 above), the use of ACLOCAL_M4_SOURCES should be considered
1711 obsolete and will be flagged as such when running `automake
1716 - Defining programs conditionally using Automake conditionals no
1717 longer leads to a combinatorial explosion. The following
1718 construct used to be troublesome when used with dozens of
1733 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1735 - Due to implementation constraints, previous versions of Automake
1736 proscribed multiple conditional definitions of some variables
1746 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1747 This restriction has been lifted, and these variables now
1748 support multiple conditional definitions as do other variables.
1750 - Cleanup the definitions of $(distdir) and $(top_distdir).
1751 $(top_distdir) now points to the root of the distribution
1752 directory created during `make dist', as it did in Automake 1.4,
1753 not to the root of the build tree as it did in intervening
1754 versions. Furthermore these two variables are now only defined in
1755 the top level Makefile, and passed to sub-directories when running
1758 - The --no-force option now correctly checks the Makefile.in's
1759 dependencies before deciding not to update it.
1761 - Do not assume that make files are called Makefile in cleaning rules.
1763 - Update .info files in the source tree, not in the build tree. This
1764 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1765 used to update these files in the build tree (previous versions did
1766 it in the source tree too), and it caused several problems, varying
1767 from mere annoyance to portability issues.
1769 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1770 when --add-missing and --force-missing are used. For backward
1771 compatibility --add-missing will continue to install COPYING (in
1772 `gnu' strictness) when none of these three files exist, but this
1773 use is deprecated: you should better choose a license yourself and
1774 install it once for all in your source tree (and in your code
1777 - Fix ylwrap so that it does not overwrite header files that haven't
1778 changed, as the inline rule already does.
1780 - User-defined rules override automake-defined rules for the same
1781 targets, even when rules do not have commands. This is not new
1782 (and was documented), however some of the automake-generated
1783 rules have escaped this principle in former Automake versions.
1784 Rules for the following targets are affected by this fix:
1786 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1787 info, info-am, install-data-am, install-exec-am, install-info,
1788 install-info-am, install-man, installcheck-am, maintainer-clean,
1789 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1790 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1792 Practically it means that an attempt to supplement the dependencies
1793 of some target, as in
1795 clean: my-clean-rule
1797 will now *silently override* the automake definition of the
1798 rule for this target. Running `automake -Woverride' will diagnose
1799 all such overriding definitions.
1801 It should be noted that almost all of these targets support a *-local
1802 variant that is meant to supplement the automake-defined rule
1803 (See node `Extending' in the manual). The above rule should
1806 clean-local: my-clean-rule
1808 These *-local targets have been documented since at least
1809 Automake 1.2, so you should not fear the change if you have
1810 to support multiple automake versions.
1814 - The Automake manual is now distributed under the terms of the GNU FDL.
1816 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1818 - core dumps are no longer removed by the cleaning rules. There are
1819 at least three reasons for this:
1820 1. These files should not be created by any build step,
1821 so their removal do not fit any of the cleaning rules.
1822 Actually, they may be precious to the developer.
1823 2. If such file is created during a build, then it's clearly a
1824 bug Automake should not hide. Not removing the file will
1825 cause `make distcheck' to complain about its presence.
1826 3. Operating systems have different naming conventions for
1827 core dump files. A core file on one system might be a
1828 completely legitimate data file on another system.
1830 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1831 defined by Automake. This means that any definition in the
1832 environment will be used, unless overridden in the Makefile.am or
1833 on the command line. The old behavior, where these variables were
1834 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1835 AC_ARG_VARing each variable from configure.ac.
1837 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1838 documented. (The is not a new feature, these variables have
1839 been there since at least Automake 1.4.)

1843 Bugs fixed in 1.7.9:
1844 * Fix install-strip to work with nobase_ binaries.
1845 * Fix renaming of #line directives in ylwrap.
1846 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1848 Bugs fixed in 1.7.8:

1853 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1855 Bugs fixed in 1.7.7:
1856 * The implementation of automake's --no-force option is unreliable,
1857 so this option is ignored in this version. A real fix will appear in
1858 Automake 1.8. (Debian Bug #206299)
1859 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1860 argument is given. (PR/399)

1872 Bugs fixed in 1.7.6:
1873 * Fix depcomp's icc mode for ICC 7.1.
1874 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1875 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1876 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1877 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1878 * Remove Latin-1 characters from elisp-comp.
1879 * Update the manual's @dircategory to match the Free Software Directory.
1881 Bugs fixed in 1.7.5:
1882 * Update install-sh's license to remove an advertising clause.
1883 (Debian bug #191717)
1884 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1885 that caused invalid Makefile.ins to be generated.
1886 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1887 * New FAQ entry: renamed objects.
1889 Bugs fixed in 1.7.4:
1890 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1891 the Emacs implementation)
1892 * Fix output of aclocal.m4 dependencies in subdirectories.
1893 * Use `mv -f' instead of `mv' in fastdep rules.
1894 * Upgrade mdate-sh to work on OS/2.
1895 * Don't byte-compile elisp files when ELCFILES is set empty.
1896 (this documented feature was broken by 1.7.3)
1897 * Diagnose trailing backslashes on last line of Makefile.am.
1898 * Diagnose whitespace following trailing backslashes.
1899 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
1900 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
1902 * `make install' will build `BUILT_SOURCES' first.
1903 * Minor documentation fixes.
1905 Bugs fixed in 1.7.3:
1906 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1907 * Query distutils for `pythondir' and `pythonexecdir', instead of
1908 using an hardcoded path. This should allow builds on 64-bit
1909 distributions that usually use lib64/ instead of lib/.
1910 * AM_PATH_PYTHON will also search for python2.3.
1911 * elisp files are now built all at once instead of one by one. Besides
1912 incurring a speed-up, this is required to support interdependent elisp files.
1913 * Support for DJGPP:
1914 - `make distcheck' will now work in `_inst/' and `_build' instead
1915 of `=inst/' and `=build/'
1916 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1917 - install/uninstall `*.i[0-9][0-9]'-style info files
1918 - more changes that affect only the Automake package (not its output)
1919 * Fix some incompatibilities with upcoming perl-5.10.
1920 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1921 PACKAGE and VERSION.
1923 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1924 is troublesome with gcc and Solaris compilers. (PR/385)
1925 - makedepend mode: work with Libtool. (PR/385 too)
1927 * better support for unusual gettext setups, such as multiple po/ directories
1929 - Flag missing po/ and intl/ directories as warnings, not errors.
1930 - Disable these warnings if po/ does not exist.
1931 * Noteworthy manual updates:
1933 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1935 - Document `AM_YFLAGS = -d'. (PR/382)
1937 Bugs fixed in 1.7.2:
1938 * Fix installation and uninstallation of Info files built in subdirectories.
1939 * Do not run `./configure --with-included-gettext' during `make distcheck'
1940 if AM_GNU_GETTEXT([external]) is used.
1941 * Correctly uninstall renamed man pages.
1942 * Do not strip escaped newline in variables defined in one condition
1943 and augmented in another condition.
1944 * Fix ansi2knr rules for LIBOBJS sources.
1945 * Clean all known Texinfo index files, not only those which appear to
1946 be used, because we cannot know which indexes are used in included files.
1947 (PR/375, Debian Bug #168671)
1948 * Honor only the first @setfilename seen in a Texinfo file.
1949 * Treat "required file X not found" diagnostics as errors (exit status 1).
1950 * Don't complain that a required file is not found when it is a Makefile
1952 * Don't use single suffix inference rules when building `.info'-less
1953 Info files, for the sake of Solaris make.
1954 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1955 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1956 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1957 * Fix building of deansified files from subdirectories. (PR/370)
1958 * Add missing `fi' in the .c->.obj rules.
1959 * Improve install-sh to work even when names contain spaces or certain
1960 (but not all) shell metachars.
1961 * Fix the following spurious failures in the test suite:
1962 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1963 * Noteworthy manual updates:
1964 - Augment the section about BUILT_SOURCES.
1965 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1967 Bugs fixed in 1.7.1:
1968 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1970 * Aclocal should now recognize macro names containing parentheses, e.g.
1971 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1972 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1974 * Install Python files even if they were built. (PR/369)
1975 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1976 version might not be defined in the latter. (PR/358)
1977 * Reorder arguments passed to a couple of commands, so things works
1978 when POSIXLY_CORRECT=1.
1979 * Fix a regex that can cause Perl to segfault on large input.
1981 * Fix distribution of packages that have some sources defined conditionally,
1982 as in the `Conditional compilation using Automake conditionals' example
1984 * Fix spurious test suite failures on IRIX.
1985 * Don't report a required variable as undefined if it has been
1986 defined conditionally for the "right" conditions.
1987 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1988 `make distcheck' fails.
1989 * Fix distribution of included Makefile fragment, so we don't create
1990 spurious directories in the distribution. (PR/366)
1991 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1994 * Autoconf 2.54 is required.
1995 * `aclocal' and `automake' will no longer warn about obsolete
1996 configure macros. This is done by `autoconf -Wobsolete'.
1997 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1998 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1999 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
2000 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
2001 `configure.ac' for you.
2002 * Support for per-program and per-library `_CPPFLAGS'.
2003 * New `ctags' target (builds CTAGS files).
2004 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
2005 (see `automake --help' or the manual for a list of them).
2006 * Honor the WARNINGS environment variable.
2007 * Omit the call to depcomp when using gcc3: call the compiler directly.
2008 * A new option, std-options, tests that programs support --help and --version
2009 when `make installcheck' is run. This is enabled by --gnits.
2010 * Texinfo rules now support the `ps' and `pdf' targets.
2011 * Info files are now created in the build directory, not the source directory.
2012 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
2014 * `make distcheck' will enforce DESTDIR support by attempting
2016 * `+=' can be used in conditionals, even if the augmented variable
2017 was defined for another condition.
2018 * Makefile fragments (inserted with `include') are always distributed.
2019 * Use Autoconf's --trace interface to inspect configure.ac and get
2020 a more accurate view of it.
2021 * Add support for extending aclocal's default macro search path
2022 using a `dirlist' file within the aclocal directory.
2023 * automake --output-dir is deprecated.
2024 * The part of the distcheck target that checks whether uninstall actually
2025 removes all installed files has been moved in a separate target,
2026 distuninstallcheck, so it can be overridden easily.
2030 * Support for AM_INIT_GETTEXT([external])
2031 * Bug fixes, including:
2032 - Fix Automake's own `make install' so it works even if `ln' doesn't.
2033 - nobase_ programs and scripts honor --program-transform correctly.
2034 - Erase configure.lineno during `make distclean'.
2035 - Erase YACC and LEX outputs during `make maintainer-clean'.
2038 * Many bug fixes, including:
2039 - Requiring the current version works.
2040 - Fix "$@" portability issues (for Zsh).
2041 - Fix output of dummy dependency files in presence of post-processed
2043 - Don't compute dependencies in background to avoid races with libtool.
2044 - Fix handling of _OBJECTS variables for targets sharing source variables.
2045 - Check dependency mode for Java when AM_PROG_GCJ is used.
2048 * automake --output-dir is deprecated
2049 * Many bug fixes, including:
2050 - Don't choke on AM_LDFLAGS definitions.
2051 - Clean libtool objects from subdirectories.
2052 - Allow configure variables with reserved suffix and unknown prefix
2053 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
2054 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
2057 * Autoconf 2.52 is required.
2058 * automake no longer run libtoolize.
2059 This is the job of autoreconf (from GNU Autoconf).
2060 * `dist' generates all the archive flavors, as did `dist-all'.
2061 * `dist-gzip' generates the Gzip tar file only.
2062 * Combining Automake Makefile conditionals no longer lead to a combinatorial
2063 explosion. Makefile.in's keep a reasonable size.
2064 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
2065 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
2067 * `#line' of Lex and Yacc files are properly set.
2068 * EXTRA_DIST can contain generated directories.
2069 * Support for dot-less extensions in suffix rules.
2070 * The part of the distcheck target that checks whether distclean actually
2071 cleans all built files has been moved in a separate target, distcleancheck,
2072 so it can be overridden easily.
2073 * `make distcheck' will pass additional options defined in
2074 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
2075 * Fixed CDPATH portability problems, in particular for MacOS X.
2076 * Fixed handling of nobase_ targets.
2077 * Fixed support of implicit rules leading to .lo objects.
2078 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
2079 * Added uninstall-hook target
2080 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
2081 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
2082 (Note that "pkgname" is not "tarname", see the manual for details.)
2083 It is also possible to pass a list of global Automake options as
2084 first argument to this new form of AM_INIT_AUTOMAKE.
2085 * Compiler-based assembler is now called `CCAS'; people expected `AS'
2086 to be a real assembler.
2087 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
2088 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
2089 * aclocal and automake are also installed with the version number
