3 * Obsolete features removed:
5 - The automake-provided $(mkdir_p) make variable, @mkdir_p@ configure
6 time substitution and AM_PROG_MKDIR m4 macro have been removed. They
7 had been obsolete since automake 1.10, and actively deprecated since
10 - The deprecated aclocal option '--acdir' has been removed. You
11 should use the options '--automake-acdir' and '--system-acdir'
12 instead (which have been introduced in Automake 1.11.2).
14 - The following long-obsolete m4 macros have been removed:
16 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
17 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
18 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
19 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
20 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
21 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
22 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
23 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
24 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
25 of the now-removed automatic de-ANSI-fication
28 - All the "old alias" macros in 'm4/obsolete.m4' have been removed.
30 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
34 * Deprecated obsolescent features:
36 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
37 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
38 m4 macro are deprecated, eliciting a warning in the 'obsolete'
39 category. They will be removed in the next major version (1.13).
41 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
45 * WARNING: Future backward-incompatibilities!
47 - Starting from the next major Automake version (1.13), the rules to
48 build pdf, ps and dvi output from Texinfo input will use the '--tidy'
49 option by default. Since such an option was introduced in Texinfo
50 4.9, this means that Makefiles generated by future Automake versions
51 will require at least that version of Texinfo.
53 - Starting from the next major Automake version (1.13), the parallel
54 testsuite harness (previously only enabled by the 'parallel-tests'
55 option) will become the default one; the older serial testsuite
56 harness will still be available through the use of the 'serial-tests'
59 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option)
60 will be deprecated in the next minor version of Automake (1.12.1) and
61 removed in the next major version (1.13).
63 - Support for the two- and three-arguments invocation forms of the
64 AM_INIT_AUTOMAKE macro will be deprecated in the next minor version
65 of Automake (1.12.1) and removed in the next major version (1.13).
67 - The exact order in which the directories in the aclocal macro
68 search path are looked up is probably going to be changed in the
69 next Automake release (1.13).
71 * Obsolete features removed:
73 - The never documented nor truly used script 'acinstall' has been
76 - Support for automatic de-ANSI-fication has been removed.
78 - The support for the "obscure" multilib feature has been removed
79 from Automake core (but remains available in the 'contrib/'
80 directory of the Automake distribution).
82 - Support for ".log -> .html" conversion and the check-html and
83 recheck-html targets has been removed from Automake core (but
84 remains available in the 'contrib/' directory of the Automake
87 - The deprecated 'lzma' compression format for distribution archives
88 has been removed, in favor of 'xz' and 'lzip'.
90 - The obsolete AM_WITH_REGEX macro has been removed.
92 - The long-deprecated options '--output-dir', '--Werror' and
93 '--Wno-error' have been removed.
95 - The chapter on the history of Automake has been moved out of the
96 reference manual, into a new dedicated Texinfo file.
100 - New 'cscope' target to build a cscope database for the source tree.
102 * Changes to Automake-generated testsuite harnesses:
104 - The new automake option 'serial-tests' has been introduced. It can
105 be used to explicitly instruct automake to use the older serial
106 testsuite harness. This is still the default at the moment, but it
107 might change in future versions.
109 - The 'recheck' target (provided by the parallel testsuite harness) now
110 depends on the 'all' target. This allows for a better user-experience
111 in test-driven development. See automake bug#11252.
113 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
114 and unexpected or internal error, or a failure to set up the test case
115 scenario) have their outcome reported as an 'ERROR' now. Previous
116 versions of automake reported such an outcome as a 'FAIL' (the only
117 difference with normal failures being that hard errors were counted
118 as failures even when the test originating them was listed in
121 - The testsuite summary displayed by the parallel-test harness has a
122 completely new format, that always list the numbers of passed, failed,
123 xfailed, xpassed, skipped and errored tests, even when these numbers
124 are zero (but using smart coloring when the color-tests option is in
127 - The default testsuite driver offered by the 'parallel-tests' option is
128 now implemented (partly at least) with the help of automake-provided
129 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
130 on code in the generated Makefile.in.
131 This has two noteworthy implications. The first one is that projects
132 using the 'parallel-tests' option should now either run automake with
133 the '--add-missing' option, or manually copy the 'test-driver' script
134 into their tree. The second, and more important, implication is that
135 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
136 not be used anymore to define a test runner, and the command specified
137 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
138 program or script. For example, this is still a valid usage (albeit
141 TESTS_ENVIRONMENT = \
142 if test -n '$(STRICT_TESTS)'; then \
143 maybe_errexit='-e'; \
147 LOG_COMPILER = $(SHELL) $$maybe_errexit
149 while this is not anymore:
151 TESTS_ENVIRONMENT = \
152 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
156 TESTS_ENVIRONMENT = \
157 run_with_perl_or_shell () \
159 if grep -q '^#!.*perl' $$1; then
165 LOG_COMPILER = run_with_perl_or_shell
167 - The package authors can now use customary testsuite drivers within
168 the framework provided by the 'parallel-tests' testsuite harness.
169 Consistently with the existing syntax, this can be done by defining
170 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
172 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
173 to redirect/define file descriptors used by the test scripts.
175 - The parallel-tests harness generates now, in addition the '.log' files
176 holding the output produced by the test scripts, a new set of '.trs'
177 files, holding "metadata" derived by the execution of the test scripts;
178 among such metadata are the outcomes of the test cases run by a script.
180 - Initial and still experimental support for the TAP test protocol is
183 * Changes to Yacc and Lex support:
185 - C source and header files derived from non-distributed Yacc and/or
186 Lex sources are now removed by a simple "make clean" (while they were
187 previously removed only by "make maintainer-clean").
189 - Slightly backward-incompatible change, relevant only for use of Yacc
190 with C++: the extensions of the header files produced by the Yacc
191 rules are now modelled after the extension of the corresponding
192 sources. For example, yacc files named "foo.y++" and "bar.yy" will
193 produce header files named "foo.h++" and "bar.hh" respectively, where
194 they would have previously produced header files named simply "foo.h"
195 and "bar.h". This change offers better compatibility with 'bison -o'.
197 * Miscellaneous changes:
199 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
200 rather than 1, if the vala compiler found is too old.
202 - The build system of Automake itself now avoids the use of make
203 recursion as much as possible.
205 - Automake now prefers to quote 'like this' or "like this", rather
206 than `like this', in diagnostic message and generated Makefiles,
207 to accommodate the new GNU Coding Standards recommendations.
209 - Automake has a new option '--print-libdir' that prints the path of the
210 directory containing the Automake-provided scripts and data files.
212 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
214 - The rules to create pdf, dvi and ps output from Texinfo files now
215 works better with modern 'texi2dvi' script, by explicitly passing
216 it the '--clean' option to ensure stray auxiliary files are not
217 left to clutter the build directory.
219 - Automake can now generate silenced rules for texinfo outputs.
221 - Some auxiliary files that are automatically distributed by Automake
222 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
223 C sources) might now be listed in the DIST_COMMON variable in many
224 Makefile.in files, rather than in the top-level one.
226 - Messages of types warning or error from 'automake' and 'aclocal'
227 are now prefixed with the respective type, and presence of -Werror
230 - Automake's early configure-time sanity check now tries to avoid
231 sleeping for a second, which slowed down cached configure runs
232 noticeably. In that case, it will check back at the end of the
233 configure script to ensure that at least one second has passed, to
234 avoid time stamp issues with makefile rules rerunning autotools
237 - The warnings in the category 'extra-portability' are now enabled by
238 '-Wall'. In previous versions, one has to use '-Wextra-portability'
243 - Various minor bugfixes for recent or long-standing bugs.
245 * Bugs introduced by 1.11:
247 - The AM_COND_IF macro also works if the shell expression for the
248 conditional is no longer valid for the condition.
250 - The automake-provided parallel testsuite harness does not fail anymore
251 with BSD make used in parallel mode when there are test scripts in a
252 subdirectory, like in:
254 TESTS = sub/foo.test sub/bar.test
256 * Long-standing bugs:
258 - Automake's own build system finally have a real "installcheck" target.
260 - Vala-related cleanup rules are now more complete, and work better in
263 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
264 now automatically distributed also if the directory of the auxiliary
265 files coincides with the top-level directory.
267 - Automake now detects the presence of the '-d' flag in the various
268 '*YFLAGS' variables even when their definitions involve indirections
269 through other variables, such as in:
271 AM_YFLAGS = $(foo_opts)
273 - Automake now complains if a '*YFLAGS' variable has any conditional
274 content, not only a conditional definition.
276 - Explicit enabling and/or disabling of Automake warning categories
277 through the '-W...' options now always takes precedence over the
278 implicit warning level implied by Automake strictness (foreign, gnu
279 or gnits), regardless of the order in which such strictness and
280 warning flags appear. For example, a setting like:
281 AUTOMAKE_OPTIONS = -Wall --foreign
282 will cause the warnings in category 'portability' to be enabled, even
283 if those warnings are by default disabled in 'foreign' strictness.
285 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
287 Bugs fixed in 1.11.5:
289 * Bugs introduced by 1.11.3:
291 - Vala files with '.vapi' extension are now recognized and handled
292 correctly again. See automake bug#11222.
294 - Vala support work again for projects that contain some program
295 built from '.vala' (and possibly '.c') sources and some other
296 program built from '.c' sources *only*. See automake bug#11229.
298 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
302 * Miscellaneous changes:
304 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
305 symbol index) modifiers as well as the "s" action, as the symbol index
306 is created unconditionally by Microsoft lib. Also, the "q" (quick)
307 action is now a synonym for "r" (replace). Also, the script has been
308 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
310 - When the 'compile' script is used to wrap MSVC, it now accepts an
311 optional space between the -I, -L and -l options and their respective
312 arguments, for better POSIX compliance.
314 - There is an initial, experimental support for automatic dependency
315 tracking with tcc (the Tiny C Compiler). Its associated depmode is
316 currently recognized as "icc" (but this and other details are likely
317 to change in future versions).
319 - Automatic dependency tracking now works also with the IBM XL C/C++
320 compilers, thanks to the new new depmode 'xlc'.
322 Bugs fixed in 1.11.4:
324 * Bugs introduced by 1.11.2:
326 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
327 don't cause spurious failures upon "make install" anymore.
329 - The user can now instruct the 'uninstall-info' rule not to update
330 the '${infodir}/dir' file by exporting the environment variable
331 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
332 with how the 'install-info' rule operates since automake 1.11.2.
334 * Long-standing bugs:
336 - It is now possible for a foo_SOURCES variable to hold Vala sources
337 together with C header files, as well as with sources and headers for
338 other supported languages (e.g., C++). Previously, only mixing C and
339 Vala sources was supported.
341 - If "aclocal --install" is used, and the first directory specified with
342 '-I' is non-existent, aclocal will now create it before trying to copy
345 - An empty declaration of a "foo_PRIMARY" don't cause anymore the
346 generated install rules to create an empty $(foodir) directory;
347 for example, if Makefile.am contains something like:
351 pkglibexec_SCRIPTS += bar.sh
354 the $(pkglibexec) directory will not be created upon "make install".
356 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
360 * Miscellaneous changes:
362 - Automake's own build system is more silent by default, making use of
363 the 'silent-rules' option.
365 - The master copy of the `gnupload' script is now maintained in gnulib,
368 - The `missing' script doesn't try to wrap calls to `tar' anymore.
370 - "make dist" doesn't wrap `tar' invocations with the `missing' script
371 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
372 shouldn't be using BTW ;-) does not invoke the missing script anymore
373 to wrap tar, but simply invokes the `tar' program itself.
375 - "make dist" can now create lzip-compressed tarballs.
377 - In the Automake info documentation, the Top node and the nodes about
378 the invocation of the automake and aclocal programs have been renamed;
379 now, calling "info automake" will open the Top node, while calling
380 "info automake-invocation" and "info aclocal-invocation" will access
381 the nodes about the invocation of respectively automake and aclocal.
383 - Automake is now distributed as a gzip-compressed and an xz-compressed
384 tarball. Previously, bzip2 was used instead of xz.
386 - The last relics of Python 1.5 support have been removed from the
387 AM_PATH_PYTHON macro.
389 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
390 and adds them to the normal list of dependencies, but without
391 overwriting the foo_DEPENDENCIES variable, which is normally computed
394 Bugs fixed in 1.11.3:
396 * Bugs introduced by 1.11.2:
398 - Automake now correctly recognizes the prefix/primary combination
399 `pkglibexec_SCRIPTS' as valid.
401 - The parallel-tests harness doesn't trip anymore on sed implementations
402 with stricter limits on the length of input lines (problem seen at
405 * Long-standing bugs:
407 - The "deleted header file problem" for *.am files is avoided by stub
408 rules. This allows `make' to trigger a rerun of `automake' also if
409 some previously needed `.am' file has been removed.
411 - The `silent-rules' option now generates working makefiles even
412 for the uncommon `make' implementations that do not support the
413 nested-variables extension to POSIX 2008. For such `make'
414 implementations, whether a build is silent is determined at
415 configure time, and cannot be overridden at make time with
416 `make V=0' or `make V=1'.
418 - Vala support now works better in VPATH setups.
420 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
424 * Changes to aclocal:
426 - The `--acdir' option is deprecated. Now you should use the new options
427 `--automake-acdir' and `--system-acdir' instead.
429 - The `ACLOCAL_PATH' environment variable is now interpreted as a
430 colon-separated list of additional directories to search after the
431 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
432 and before the system acdir (by default ${prefix}/share/aclocal).
434 * Miscellaneous changes:
436 - The Automake support for automatic de-ANSI-fication has been
437 deprecated. It will probably be removed in the next major Automake
440 - The `lzma' compression scheme and associated automake option `dist-lzma'
441 is obsoleted by `xz' and `dist-xz' due to upstream changes.
443 - You may adjust the compression options used in dist-xz and dist-bzip2.
444 The default is now merely -e for xz, but still -9 for bzip; you may
445 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
446 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
448 - The `compile' script now converts some options for MSVC for a better
449 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
451 - The py-compile script now accepts empty arguments passed to the options
452 `--destdir' and `--basedir', and complains about unrecognized options.
453 Moreover, a non-option argument or a special `--' argument terminates
456 - A developer that needs to pass specific flags to configure at "make
457 distcheck" time can now, and indeed is advised to, do so by defining
458 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
459 instead of the old DISTCHECK_CONFIGURE_FLAGS.
460 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
461 user; still, the old Makefile.am files that used to define it will
462 still continue to work as before.
464 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
465 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
466 This new macro is required for LIBRARIES and LTLIBRARIES when automake
467 is run with -Wextra-portability and -Werror.
469 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
470 file generated by automake-provided rules by defining the special make
471 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
473 - The `install-info' rule can now be instructed not to create/update
474 the `${infodir}/dir' file, by exporting the new environment variable
475 `AM_UPDATE_INFO_DIR' to the value "no".
477 Bugs fixed in 1.11.2:
479 * Bugs introduced by 1.11:
481 - The parallel-tests driver no longer produces erroneous results with
482 Tru64/OSF 5.1 sh upon unreadable log files.
484 - The `parallel-tests' test driver does not report spurious successes
485 when used with concurrent FreeBSD make (e.g., "make check -j3").
487 - When the parallel-tests driver is in use, automake now explicitly
488 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
489 instead of issuing confusing and apparently unrelated error messages
490 (e.g., "non-POSIX variable name", "bad characters in variable name",
491 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
492 silently producing broken `Makefile.in' files.
494 - The `silent-rules' option now truly silences all compile rules, even
495 when dependency tracking is disabled. Also, when `silent-rules' is
496 not used, `make' output no longer contains spurious backslash-only
497 lines, thus once again matching what Automake did before 1.11.
499 - The AM_COND_IF macro also works if the shell expression for the
500 conditional is no longer valid for the condition.
502 * Long-standing bugs:
504 - The order of Yacc and Lex flags is fixed to be consistent with other
505 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
506 $(LFLAGS), so that the user variables override the developer variables.
508 - "make distcheck" now correctly complains also when "make uninstall"
509 leaves one and only one file installed in $(prefix).
511 - A "make uninstall" issued before a "make install", or after a mere
512 "make install-data" or a mere "make install-exec" does not spuriously
515 - Automake now warns about more primary/directory invalid combinations,
516 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
518 - Rules generated by Automake now try harder to not change any files when
519 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
520 Yacc source files and the rule to update config.h.
522 - Several scripts and the parallel-tests testsuite driver now exit with
523 the right exit status upon receiving a signal.
525 - A per-Makefile.am setting of -Werror does not erroneously carry over
526 to the handling of other Makefile.am files.
528 - The code for automatic dependency tracking works around a Solaris
529 make bug triggered by sources containing repeated slashes when the
530 `subdir-objects' option was used.
532 - The makedepend and hp depmodes now work better with VPATH builds.
534 - Java sources specified with check_JAVA are no longer compiled for
535 "make all", but only for "make check".
537 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
538 and error out if `javadir' is undefined, instead of silently producing
539 a broken Makefile.in.
541 - aclocal and automake now honour the configure-time definitions of
542 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
544 - The `install-info' recipe no longer tries to guess whether the
545 `install-info' program is from Debian or from GNU, and adaptively
546 change its behaviour; this has proven to be frail and easy to
549 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
551 Bugs fixed in 1.11.1:
553 - Lots of minor bugfixes.
555 * Bugs introduced by 1.11:
557 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
558 trailing white space in the test list (`TESTS = foo $(EMPTY)').
560 * Long standing bugs:
562 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
563 even if the `--prefix' argument pointed outside of a system directory.
564 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
565 `get_python_lib' function if it points outside the configured prefix,
566 unless the `--prefix' argument was either `/usr' or below `/System'.
568 - The testsuite does not try to change the mode of `ltmain.sh' files from
569 a Libtool installation (symlinked to test directories) any more.
571 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
572 tools are preferred in a cross-compile setup.
574 - The distribution is tarred up with mode 755 now by the `dist*' targets.
575 This fixes a race condition where untrusted users could modify files
576 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
577 build directory was world-searchable. This is CVE-2009-4029.
579 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
583 * Version requirements:
585 - Autoconf 2.62 or greater is required.
587 * Changes to aclocal:
589 - The autoconf version check implemented by aclocal in aclocal.m4
590 (and new in Automake 1.10) is degraded to a warning. This helps
591 in the common case where the Autoconf versions used are compatible.
593 * Changes to automake:
595 - The automake program can run multiple threads for creating most
596 Makefile.in files concurrently, if at least Perl 5.7.2 is available
597 with interpreter-based threads enabled. Set the environment variable
598 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
599 enable this experimental feature.
601 * Changes to Libtool support:
603 - Libtool generic flags are now passed to the install and uninstall
606 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
607 config.lt is removed correctly now.
611 - subdir-object mode works now with Fortran (F77, FC, preprocessed
612 Fortran, and Ratfor).
614 - For files with extension .f90, .f95, .f03, or .f08, the flag
615 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
617 - Files with extension .sx are also treated as preprocessed assembler.
619 - The default source file extension (.c) can be overridden with
620 AM_DEFAULT_SOURCE_EXT now.
622 - Python 3.0 is supported now, Python releases prior to 2.0 are no
625 - AM_PATH_PYTHON honors python's idea about the site directory.
627 - There is initial support for the Vala programming language, when using
630 * Miscellaneous changes:
632 - Automake development is done in a git repository on Savannah now, see
634 http://git.sv.gnu.org/gitweb/?p=automake.git
636 A read-only CVS mirror is provided at
638 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
639 checkout -d automake HEAD
641 - "make dist" can now create xz-compressed tarballs,
642 as well as (deprecated?) lzma-compressed tarballs.
644 - `automake --add-missing' will by default install the GPLv3 file as
645 COPYING if it is missing. It will also warn that the license file
646 should be added to source control. Note that Automake will never
647 overwrite an existing COPYING file, even when the `--force-missing'
650 - The manual is now distributed under the terms of the GNU FDL 1.3.
652 - Automake ships and installs man pages for automake and aclocal now.
654 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
656 - install-sh supports -C, which does not update the installed file
657 (and its time stamps) if the contents did not change.
659 - The `gnupload' script has been revamped.
661 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
663 - The targets `install' and `uninstall' are more efficient now, in that
664 for example multiple files from one Automake variable such as
665 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
666 invocation if they do not have to be renamed.
668 Both install and uninstall may sometimes enter (`cd' into) the target
669 installation directory now, when no build-local scripts are used.
671 Both install and uninstall do not fail anymore but do nothing if an
672 installation directory variable like `bindir' is set to the empty string.
674 For built-in rules, `make install' now fails reliably if installation
675 of a file failed. Conversely, `make uninstall' even succeeds when
676 issued multiple times.
678 These changes may need some adjustments from users: For example,
679 some `install' programs refuse to install multiple copies of the
680 same file in one invocation, so you may need to remove duplicate
681 entries from file lists.
683 Also, within one set of files, say, nobase_data_DATA, the order of
684 installation may be changed, or even unstable among different hosts,
685 due to the use of associative arrays in awk. The increased use of
686 awk matches a similar move in Autoconf to provide for better scaling.
688 Further, most undocumented per-rule install command variables such as
689 binSCRIPT_INSTALL have been removed because they are not needed any
690 more. Packages which use them should be using the appropriate one of
691 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
692 counterpart, depending on the type of files and the need for automatic
693 target directory creation.
695 - The "deleted header file problem" for *.m4 files is avoided by
696 stub rules. This allows `make' to trigger a rerun of `aclocal'
697 also if some previously needed macro file has been removed.
699 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
700 an otherwise up to date tree.
702 - The `color-tests' option causes colored test result output on terminals.
704 - The `parallel-tests' option enables a new test driver that allows for
705 parallel test execution, inter-test dependencies, lazy test execution
706 for unit-testing, re-testing only failed tests, and formatted result output
707 as RST (reStructuredText) and HTML. Enabling this option may require some
708 changes to your test suite setup; see the manual for details.
710 - The `silent-rules' option enables Linux kernel-style silent build output.
711 This option requires the widely supported but non-POSIX `make' feature
712 of recursive variable expansion, so do not use it if your package needs
713 to build with `make' implementations that do not support it.
715 To enable less verbose build output, the developer has to use the Automake
716 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
717 macro. The user may then set the default verbosity by passing the
718 `--enable-silent-rules' option to `configure'. At `make' run time, this
719 default may be overridden using `make V=0' for less verbose, and `make V=1'
720 for backward-compatible verbose output.
722 - New prefix `notrans_' for manpages which should not be transformed
723 by --program-transform.
725 - New macro AM_COND_IF for conditional evaluation and conditional
728 - For AC_CONFIG_LINKS, if source and destination are equal, do not
729 remove the file in a non-VPATH build. Such setups work with Autoconf
732 - AM_MAINTAINER_MODE now allows for an optional argument specifying
735 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
736 useful especially for multi-line values.
738 - Automake's early configure-time sanity check now diagnoses an
739 unsafe absolute source directory name and makes configure fail.
741 - The Automake macros and rules cope better with whitespace in the
742 current directory name, as long as the relative path to `configure'
743 does not contain whitespace. To this end, the values of `$(MISSING)'
744 and `$(install_sh)' may contain suitable quoting, and their expansion
745 might need `eval'uation if used outside of a makefile. These
746 undocumented variables may be used in several documented macros such
747 as $(AUTOCONF) or $(MAKEINFO).
751 * Long-standing bugs:
753 - Fix aix dependency tracking for libtool objects.
755 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
756 unnecessary use of the `compile' script.
758 - For nobase_*_LTLIBRARIES with nonempty directory components, the
759 correct `-rpath' argument is used now.
761 - `config.status --file=Makefile depfiles' now also works with the
762 extra quoting used internally by Autoconf 2.62 and newer
763 (it used to work only without the `--file=' bit).
765 - The `missing' script works better with versioned tool names.
767 - Semantics for `missing help2man' have been revamped:
769 Previously, if `help2man' was not present, `missing help2man' would have
770 the following semantics: if some man page was out of date but present, then
771 a warning would be printed, but the exit status was 0. If the man page was
772 not present at all, then `missing' would create a replacement man page
773 containing an error message, and exit with a status of 2. This does not play
774 well with `make': the next run will see this particular man page as being up
775 to date, and will only error out on the next generated man page, if any;
776 repeat until all pages are done. This was not desirable.
778 These are the new semantics: if some man page is not present, and help2man
779 is not either, then `missing' will warn and generate the replacement page
780 containing the error message, but exit successfully. However, `make dist'
781 will ensure that no such bogus man pages are packaged into a tarball.
783 - Targets provided by automake behave better with `make -n', in that they
784 take care not to create files.
786 - `config.status Makefile... depfiles' works fine again in the presence of
787 disabled dependency tracking.
789 - The default no-op recursive rules for these targets also work with BSD make
790 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
792 - `make distcheck' works also when both a directory and some file below it
793 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
795 - Texinfo dvi, ps, pdf, and html output files are not removed upon
796 `make mostlyclean' any more; only the LaTeX by-products are.
798 - Renamed objects also work with the `subdir-objects' option and
799 source file languages which Automake does not know itself.
801 - `automake' now correctly complains about variable assignments which are
802 preceded by a comment, extend over multiple lines with backslash-escaped
803 newlines, and end in a comment sign. Previous versions would silently
804 and wrongly ignore such assignments completely.
806 * Bugs introduced by 1.10:
808 - Fix output of dummy dependency files in presence of post-processed
809 Makefile.in's again, but also cope with long lines.
811 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
812 that have been declared as programs in the same Makefile.
813 This is for consistency with the analogous change to TESTS in 1.10.
815 - Fix order of standard includes to again be `-I. -I$(srcdir)',
816 followed by directories containing config headers.
818 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
822 * Version requirements:
824 - Autoconf 2.60 or greater is required.
826 - Perl 5.6 or greater is required.
828 * Changes to aclocal:
830 - aclocal now also supports -Wmumble and -Wno-mumble options.
832 - `dirlist' entries (for the aclocal search path) may use shell
833 wildcards such as `*', `?', or `[...]'.
835 - aclocal supports an --install option that will cause system-wide
836 third-party macros to be installed in the local directory
837 specified with the first -I flag. This option also uses #serial
838 lines in M4 files to upgrade local macros.
840 The new aclocal options --dry-run and --diff help to review changes
841 before they are installed.
843 - aclocal now outputs an autoconf version check in aclocal.m4 in
844 projects using automake.
846 For a few years, automake and aclocal have been calling autoconf
847 (or its underlying engine autom4te) to accurately retrieve the
848 data they need from configure.ac and its siblings. Doing so can
849 only work if all autotools use the same version of autoconf. For
850 instance a Makefile.in generated by automake for one version of
851 autoconf may stop working if configure is regenerated with another
852 version of autoconf, and vice versa.
854 This new version check ensures that the whole build system has
855 been generated using the same autoconf version.
857 * Support for new Autoconf macros:
859 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
861 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
862 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
863 in different directories. However, only one instance of such a
864 library objects directory is supported.
866 * Change to Libtool support:
868 - Libtool generic flags (those that go before the --mode=MODE option)
869 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
871 * Yacc and Lex changes:
873 - The rebuild rules for distributed Yacc and Lex output will avoid
874 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
877 - ylwrap is now always used for lex and yacc source files,
878 regardless of whether there is more than one source per directory.
882 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
883 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
884 tracking, unlike non-preprocessed assembler (*.s).
886 - subdir-object mode works now with Assembler. Automake assumes
887 that the compiler understands `-c -o'.
889 - Preprocessed assembler (*.S) compilation now also honors
890 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
892 - Improved support for Objective C:
893 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
894 - A new section of the manual documents the support.
896 - New support for Unified Parallel C:
897 - AM_PROG_UPC looks for a UPC compiler.
898 - A new section of the manual documents the support.
900 - Per-target flags are now correctly handled in link rules.
902 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
903 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
904 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
905 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
907 The fix for compiler flags (i.e., using maude_CFLAGS instead of
908 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
909 is expected to work (and actually works during compilation).
911 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
912 "in addition to" breaks backward compatibility with older versions.
913 If your package used both variables, as in
915 AM_LDFLAGS = common flags
917 a_LDFLAGS = more flags
920 and assumed *_LDFLAGS would sum up, you should rewrite it as
922 AM_LDFLAGS = common flags
924 a_LDFLAGS = $(AM_LDFLAGS) more flags
927 This new behavior of *_LDFLAGS is more coherent with other
928 per-target variables, and the way *_LDFLAGS variables were
929 considered internally.
931 * New installation targets:
933 - New targets mandated by GNU Coding Standards:
938 By default they will only install Texinfo manuals.
939 You can customize them with *-local variants:
945 - The undocumented recursive target `uninstall-info' no longer exists.
946 (`uninstall' is in charge of removing all possible documentation
947 flavors, including optional formats such as dvi, ps, or info even
948 when `no-installinfo' is used.)
950 * Miscellaneous changes:
952 - Automake no longer complains if input files for AC_CONFIG_FILES
953 are specified using shell variables.
955 - clean, distribution, or rebuild rules are normally disabled for
956 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
957 AC_CONFIG_LINK specified using shell variables. However, if these
958 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
959 be able to output rules anyway.
960 (See the Automake documentation for AC_CONFIG_FILES.)
962 - $(EXEEXT) is automatically appended to filenames of TESTS
963 that have been declared as programs in the same Makefile.
964 This is mostly useful when some check_PROGRAMS are listed in TESTS.
966 - `-Wportability' has finally been turned on by default for `gnu' and
967 `gnits' strictness. This means, automake will complain about %-rules
968 or $(GNU Make functions) unless you switch to `foreign' strictness or
969 use `-Wno-portability'.
971 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
972 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
973 $(mkdir_p) variable is still defined (to the same value as
974 $(MKDIR_P)) but should be considered obsolete. If you are using
975 $(mkdir_p) in some of your rules, please plan to update them to
976 $(MKDIR_P) at some point.
978 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
979 They still work in this release, but may be withdrawn in a future one.
981 - Inline compilation rules for gcc3-style dependency tracking are
984 - Automake installs a "Hello World!" example package in $(docdir).
985 This example is used throughout the new "Autotools Introduction"
986 chapter of the manual.
988 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
992 * Makefile.in bloat reduction:
994 - Inference rules are used to compile sources in subdirectories when
995 the `subdir-objects' option is used and no per-target flags are
996 used. This should reduce the size of some projects a lot, because
997 Automake used to output an explicit rule for each such object in
1000 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1001 object that must be built with explicit rules. It just outputs
1002 the rules required to build the kind of object considered: either
1003 the two .o and .obj rules for usual objects, or the .lo rule for
1006 * Change to Libtool support:
1008 - Libtool tags are used with libtool versions that support them.
1009 (I.e., with Libtool 1.5 or greater.)
1011 - Automake is now able to handle setups where a libtool library is
1012 conditionally installed in different directories, as in
1015 lib_LTLIBRARIES = liba.la
1017 pkglib_LTLIBRARIES = liba.la
1019 liba_la_SOURCES = ...
1021 * Changes to aclocal:
1023 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1024 really evaluated, before it decides to include them in aclocal.m4.
1025 This solves nasty problems with conditional redefinitions of
1026 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1027 *.m4 files to be included in any project using these macros.
1028 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1029 most famous instance of this bug.)
1031 - Do not complain about missing conditionally AC_REQUIREd macros
1032 that are not actually used. In 1.8.x aclocal would correctly
1033 determine which of these macros were really needed (and include
1034 only these in the package); unfortunately it would also require
1035 all of them to be present in order to run. This created
1036 situations were aclocal would not work on a tarball distributing
1037 all the macros it uses. For instance running aclocal on a project
1038 containing only the subset of the Gettext macros in use by the
1039 project did not work, because gettext conditionally requires other
1042 * Portability improvements:
1044 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1045 tar-pax. The new option filename-length-max=99 helps diagnosing
1046 filenames that are too long for tar-v7. (PR/414)
1048 - Variables aumented with `+=' are now automatically flattened (i.e.,
1049 trailing backslashes removed) and then wrapped around 80 colummns
1050 (adding trailing backslashes). In previous versions, a long series
1056 would result in a single-line definition of VAR that could possibly
1057 exceed the maximum line length of some make implementations.
1059 Non-augmented variables are still output as they are defined in
1064 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1065 Works the same as the old Fortran 77 implementation; just replace
1066 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1067 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1069 - Support for conditional _LISP.
1071 - Support for conditional -hook and -local rules (PR/428).
1073 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1075 - Automake will not write any Makefile.ins after the first error it
1076 encounters. The previous Makefile.ins (if any) will be left in
1077 place. (Warnings will not prevent output, but remember they can
1078 be turned into errors with -Werror.)
1080 - The restriction that SUBDIRS must contain direct children is gone.
1083 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1084 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1086 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1088 Bugs fixed in 1.8.5:
1090 * Long-standing bugs:
1092 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1093 so that `make distclean' and `make maintainer-clean' can work.
1095 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1097 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1099 - Polish diagnostic when no input file is found.
1101 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1103 Bugs fixed in 1.8.4:
1105 * Long-standing bugs:
1107 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1108 overridden by the user.
1110 - Honor PATH_SEPARATOR in various places of the Automake package, for
1113 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1116 - Fix install-sh so it can install the `mv' binary... using `mv'.
1118 - Fix tru64 dependency tracking for libtool objects.
1120 - Work around Exuberant Ctags when creating a TAGS files in a directory
1121 without files to scan but with subdirectories to include.
1123 * Bugs introduced by 1.8:
1125 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1126 not defined in the same conditions as the _LDADD that uses it.
1128 - Do not warn when JAVAROOT is overridden, this is legitimate.
1130 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1132 Bugs fixed in 1.8.3:
1134 * Long-standing bugs:
1136 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1137 or any of the other *dir variables contain a space.
1139 Please note that Automake does not and cannot support spaces in
1140 filenames that are involved during the build. This change affects
1141 only installation paths, so that `make install' does not bomb out
1142 in packages configured with
1143 ./configure --prefix '/c/Program Files'
1145 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1146 POSIXLY_CORRECT is set.
1148 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1149 since Autoconf 2.54, which defines LIBOBJS itself.
1151 - Fix a potential (but unlikely) race condition in parallel elisp
1152 builds. (Introduced in 1.7.3.)
1154 - Do not assume that users override _DEPENDENCIES in all conditions
1155 where Automake will try to define them.
1157 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1158 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1161 This fix also affects the $(mkdir_p) variable defined since
1162 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1163 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1165 - Secure temporary directory creation in `make distcheck'. (PR/413)
1167 - Do not generate two build rules for `parser.h' when the
1168 parser appears in two different conditionals.
1170 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1171 checking. Usually ./configure will not pick this shell; so this
1172 fix only helps cases where the shell is forced to /bin/sh.
1174 * Bugs introduced by 1.8:
1176 - In some situations (hand-written `m4_include's), aclocal would
1177 call the `File::Spec->rel2abs' method, which was only introduced
1178 in Perl 5.6. This new version reestablish support Perl 5.005.
1180 It is likely that the next major Automake releases will require at
1181 least Perl 5.6. Consider upgrading your development environment
1182 if you are still using the five-year-old Perl 5.005.
1184 - Automake would sometimes fail to define rules for targets listed
1185 in variables defined in multiple conditions. For instance on
1191 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1192 `b.$(OBJEXT): b.c' rule.
1194 * New sections in manual:
1196 - Third-Party Makefiles: how to interface third party Makefiles.
1197 - Upgrading: upgrading packages to newer Automake versions.
1198 - Multiple Outputs: handling tools that produce many outputs.
1200 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1204 * A (well known) portability bug slipped in the changes made to
1205 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1206 install anything on Tru64.
1208 * Fix install rules for conditionally built python files. (This never
1211 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1215 * Bugs introduced by 1.8:
1217 - Fix Config.pm import error with old Perl versions (at least
1218 5.005_03). One symptom is that aclocal could not find its macro
1221 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1222 created by `make install' are always world readable, even if the
1223 installer happens to have an overly restrictive umask (e.g. 077).
1224 This was a mistake and has been reverted. There are at least two
1225 reasons why we must not use `-m 0755':
1226 - it causes special bits like SGID to be ignored,
1227 - it may be too restrictive (some setups expect 775 directories).
1229 - Fix aclocal to honor definitions located in files which have been
1230 m4_included manually. aclocal 1.8 had been updated to check
1231 m4_included files for new requirements, but forgot that these
1232 m4_included files can also provide new definitions.
1234 Note that if you have such a setup, we recommend you get rid of
1235 it. In the past, there was a reason to m4_include files manually:
1236 aclocal used to duplicate entire M4 files into aclocal.m4, even
1237 files that were distributed. Some packages were therefore
1238 m4_including the distributed file directly, and playing some
1239 tricks to ensure aclocal would not copy that file to aclocal.m4,
1240 in order to limit the amount of duplication. Since aclocal 1.8.x
1241 will precisely output m4_includes for local M4 files, we recommend
1242 that you clean up your setup, removing all manual m4_includes and
1243 letting aclocal output them.
1245 - Output detailed menus in the Info version if the Automake manual,
1246 so that Emacs can locate the indexes.
1248 - configure.ac and configure were listed twice in DIST_COMMON (an
1249 internal variable where Automake lists configury files to
1250 distribute). This was harmless, but unaesthetic.
1252 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1253 This was an issue only in the Automake package itself, not in
1256 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1257 DEST:SRC. This was wrong, as some packages do
1258 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1261 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1262 argument. This caused two kinds of failures:
1263 - Rules installing data in a conditionally defined directory
1264 failed when that directory was undefined. In this case no
1265 argument was supplied.
1266 - `make installdirs' failed, because several directories were
1267 passed to $(mkdir_p). This was an issue only on platform
1268 were $(mkdir_p) is implemented with `install-sh -d'.
1269 $(mkdir_p) as been changed to accept 0 or more arguments, as
1272 * Long-standing bugs:
1274 - Fix an unexpected diagnostic occurring when users attempt
1275 to override some internal variables that Automake appends to.
1277 - aclocal now scans configure.ac for macro definitions (PR/319).
1279 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1280 distributes files which are outside itself (this usually occurs
1281 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1282 from a parent package), then `make distcheck' fails due to an
1283 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1284 (tests/subpkg2.test failure)
1286 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1287 In a VPATH-build configuration, `make install' would install
1288 nobase_ files to wrong locations.
1290 - Fix a Perl `uninitialized value' diagnostic occurring when
1291 automake complains that a Texinfo file does not have a
1292 @setfilename statement.
1294 - Erase config.status.lineno during `make distclean'. This file
1295 can be created by config.status. Automake already knew about
1296 configure.lineno, but forgot config.status.lineno.
1298 - Distribute all files, even those which are built and installed
1299 conditionally. This change affects files listed in conditionally
1300 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1301 as well as those listed in conditionally defined dist_*_DATA,
1302 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1304 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1305 doesn't conform to POSIX.
1307 - Normalize help strings for configure variables and options added
1312 - Check for python2.4 in AM_PATH_PYTHON.
1314 * Spurious failures in test suite:
1316 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1317 tests/ltconv.test: fix failures with CVS Libtool.
1318 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1319 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1320 fix failures with old Texinfo versions.
1322 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1328 - The NEWS file is more verbose.
1332 - Autoconf 2.58 or greater is required.
1336 - Default source file names in the absence of a _SOURCES declaration
1337 are made by removing any target extension before appending `.c', so
1338 to make the libtool module `foo.la' from `foo.c', you only need to
1341 lib_LTLIBRARIES = foo.la
1342 foo_la_LDFLAGS = -module
1344 For backward compatibility, foo_la.c will be used instead of
1345 foo.c if this file exists or is the explicit target of a rule.
1346 However -Wobsolete will warn about this deprecated naming.
1348 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1349 of being hard-coded in each $(AR) invocation, so they can be
1350 substituted from configure.ac. This has been requested by people
1351 dealing with non-POSIX ar implementations.
1353 - New warning option: -Woverride. This will warn about any user
1354 target or variable definitions which override Automake
1357 - Texinfo rules back up and restore info files when makeinfo fails.
1359 - Texinfo rules now support the `html' target.
1360 Running this requires Texinfo 4.0 or greater.
1362 `html' is a new recursive target, so if your package mixes
1363 hand-crafted `Makefile.in's with Automake-generated
1364 `Makefile.in's, you should adjust the former to support (or
1365 ignore) this target so that `make html' recurses successfully. If
1366 you had a custom `html' rule in your `Makefile.am', it's better to
1367 rename it as `html-local', otherwise your rule will override
1368 Automake's new rule (you can check that by running `automake
1369 -Woverride') and that will stop the recursion to subdirectories.
1371 Last but not least, this `html' rule is declared PHONY, even when
1372 overridden. Fortunately, it appears that few packages use a
1373 non-PHONY `html' rule.
1375 - Any file which is m4_included from configure.ac will appear as a
1376 configure and Makefile.in dependency, and will be automatically
1379 - The rules for rebuilding Makefiles and Makefile.ins will now
1380 rebuild all Makefiles and all Makefile.ins at once when one of
1381 configure's dependencies has changed. This is considerably faster
1382 than previous implementations, where config.status and automake
1383 were run separately in each directory (this still happens when you
1384 change a Makefile.am locally, without touching configure.ac or
1385 friends). Doing this also solves a longstanding issue: these
1386 rebuild rules failed to work when adding new directories to the
1387 tree, forcing you to run automake manually.
1389 - For similar reasons, the rules to rebuild configure,
1390 config.status, and aclocal.m4 are now defined in all directories.
1391 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1392 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1393 should better define them in all directories. This is easily done
1394 using an AC_SUBST (make sure you prefix these dependencies with
1395 $(top_srcdir) since this variable will appear at different
1396 levels of the build tree).
1398 - aclocal will now use `m4_include' instead of copying local m4
1399 files into aclocal.m4. (Local m4 files are those you ship with
1400 your project, other files will be copied as usual.)
1402 Because m4_included files are automatically distributed, it means
1403 for most projects there is no point in EXTRA_DISTing the list of
1404 m4 files which are used. (You can probably get rid of
1405 m4/Makefile.am if you had one.)
1407 - aclocal will avoid touching aclocal.m4 when possible, so that
1408 Autom4te's cache isn't needlessly invalidated. This behavior can
1409 be switched off with the new `--force' option.
1411 - aclocal now uses Autoconf's --trace to detect macros which are
1412 actually used and will no longer include unused macros simply
1413 because they where mentioned. This was often the case for macros
1414 called conditionally.
1416 - New options no-dist and no-dist-gzip.
1418 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1419 py-compile, and ylwrap, now all understand --version and --help.
1421 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1422 links as part of the distclean target and including source files in
1425 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1426 argument. The latter can be used to override the default behavior
1427 (which is to abort).
1429 - Automake will exit with $? = 63 on version mismatch. (So does
1430 Autoconf 2.58) missing knows this, and in this case it will
1431 emulate the tools as if they were absent. Because older versions
1432 of Automake and Autoconf did not use this exit code, this change
1433 will only be useful in projects generated with future versions of
1436 - When using AC_CONFIG_FILES with multiple input files, Automake
1437 generates the first ".in" input file for which a ".am" exists.
1438 (Former versions would try to use only the first input file.)
1440 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1441 idiom to disable byte-compilation of lisp_LISP files, it is
1442 recommended that you switch to using lisp_DATA. Note that
1443 this is not strictly equivalent: lisp_DATA will install elisp
1444 files even if emacs is not installed, while *_LISP do not
1445 install anything unless emacs is found.
1447 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1448 available. This selection is achieved through the Makefile
1449 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1450 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1451 `$(install_sh) -m 0755 -d'.
1455 - Because `mkdir -p' is available on most platforms, and we can use
1456 `install-sh -d' when it is not, the use of the mkinstalldirs
1457 script is being phased out. `automake --add-missing' no longer
1458 installs it, and if you remove mkinstalldirs from your package,
1459 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1461 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1462 gettextize and autopoint will install it when needed. Automake
1463 will continue to define the $(mkinstalldirs) and to distribute
1464 mkinstalldirs when this script is in the source tree.
1466 - AM_PROG_CC_STDC is now empty. The content of this macro was
1467 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1468 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1469 renaming should be safe, even if you have to support several,
1470 versions of Automake, because AC_PROG_CC defines this variable
1471 since Autoconf 2.54.)
1473 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1474 variable to override the aclocal.m4 dependencies computed
1475 (inaccurately) by older versions of Automake. Because Automake
1476 now tracks configure's m4 dependencies accurately (see m4_include
1477 above), the use of ACLOCAL_M4_SOURCES should be considered
1478 obsolete and will be flagged as such when running `automake
1483 - Defining programs conditionally using Automake conditionals no
1484 longer leads to a combinatorial explosion. The following
1485 construct used to be troublesome when used with dozens of
1500 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1502 - Due to implementation constraints, previous versions of Automake
1503 proscribed multiple conditional definitions of some variables
1513 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1514 This restriction has been lifted, and these variables now
1515 support multiple conditional definitions as do other variables.
1517 - Cleanup the definitions of $(distdir) and $(top_distdir).
1518 $(top_distdir) now points to the root of the distribution
1519 directory created during `make dist', as it did in Automake 1.4,
1520 not to the root of the build tree as it did in intervening
1521 versions. Furthermore these two variables are now only defined in
1522 the top level Makefile, and passed to sub-directories when running
1525 - The --no-force option now correctly checks the Makefile.in's
1526 dependencies before deciding not to update it.
1528 - Do not assume that make files are called Makefile in cleaning rules.
1530 - Update .info files in the source tree, not in the build tree. This
1531 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1532 used to update these files in the build tree (previous versions did
1533 it in the source tree too), and it caused several problems, varying
1534 from mere annoyance to portability issues.
1536 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1537 when --add-missing and --force-missing are used. For backward
1538 compatibility --add-missing will continue to install COPYING (in
1539 `gnu' strictness) when none of these three files exist, but this
1540 use is deprecated: you should better choose a license yourself and
1541 install it once for all in your source tree (and in your code
1544 - Fix ylwrap so that it does not overwrite header files that haven't
1545 changed, as the inline rule already does.
1547 - User-defined rules override automake-defined rules for the same
1548 targets, even when rules do not have commands. This is not new
1549 (and was documented), however some of the automake-generated
1550 rules have escaped this principle in former Automake versions.
1551 Rules for the following targets are affected by this fix:
1553 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1554 info, info-am, install-data-am, install-exec-am, install-info,
1555 install-info-am, install-man, installcheck-am, maintainer-clean,
1556 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1557 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1559 Practically it means that an attempt to supplement the dependencies
1560 of some target, as in
1562 clean: my-clean-rule
1564 will now *silently override* the automake definition of the
1565 rule for this target. Running `automake -Woverride' will diagnose
1566 all such overriding definitions.
1568 It should be noted that almost all these targets support a *-local
1569 variant that is meant to supplement the automake-defined rule
1570 (See node `Extending' in the manual). The above rule should
1573 clean-local: my-clean-rule
1575 These *-local targets have been documented since at least
1576 Automake 1.2, so you should not fear the change if you have
1577 to support multiple automake versions.
1581 - The Automake manual is now distributed under the terms of the GNU FDL.
1583 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1585 - core dumps are no longer removed by the cleaning rules. There are
1586 at least three reasons for this:
1587 1. These files should not be created by any build step,
1588 so their removal do not fit any of the cleaning rules.
1589 Actually, they may be precious to the developer.
1590 2. If such file is created during a build, then it's clearly a
1591 bug Automake should not hide. Not removing the file will
1592 cause `make distcheck' to complain about its presence.
1593 3. Operating systems have different naming conventions for
1594 core dump files. A core file on one system might be a
1595 completely legitimate data file on another system.
1597 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1598 defined by Automake. This means that any definition in the
1599 environment will be used, unless overridden in the Makefile.am or
1600 on the command line. The old behavior, where these variables were
1601 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1602 AC_ARG_VARing each variable from configure.ac.
1604 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1605 documented. (The is not a new feature, these variables have
1606 been there since at least Automake 1.4.)
1608 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1610 Bugs fixed in 1.7.9:
1611 * Fix install-strip to work with nobase_ binaries.
1612 * Fix renaming of #line directives in ylwrap.
1613 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1615 Bugs fixed in 1.7.8:
1616 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1617 * Fix detection of Debian's install-info, broken since version 1.5.
1618 (Debian bug #213524).
1619 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1620 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1622 Bugs fixed in 1.7.7:
1623 * The implementation of automake's --no-force option is unreliable,
1624 so this option is ignored in this version. A real fix will appear in
1625 Automake 1.8. (Debian Bug #206299)
1626 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1627 argument is given. (PR/399)
1628 * Do not warn about leading `_' in variable names, even with -Wportability.
1629 * Support user redefinitions of TEXINFO_TEX.
1630 * depcomp: support AIX Compiler version 6.
1631 * Fix missing rebuilds during `make dist' with BSD make.
1632 (Could produce tarballs containing out-of-date files.)
1633 * Resurrect multilib support.
1634 * Noteworthy manual updates:
1635 - Extending aclocal: how to write m4 macros that won't trigger warnings
1637 - A Shared Library: Rewrite and split into subsections.
1639 Bugs fixed in 1.7.6:
1640 * Fix depcomp's icc mode for ICC 7.1.
1641 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1642 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1643 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1644 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1645 * Remove Latin-1 characters from elisp-comp.
1646 * Update the manual's @dircategory to match the Free Software Directory.
1648 Bugs fixed in 1.7.5:
1649 * Update install-sh's license to remove an advertising clause.
1650 (Debian bug #191717)
1651 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1652 that caused invalid Makefile.ins to be generated.
1653 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1654 * New FAQ entry: renamed objects.
1656 Bugs fixed in 1.7.4:
1657 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1658 the Emacs implementation)
1659 * Fix output of aclocal.m4 dependencies in subdirectories.
1660 * Use `mv -f' instead of `mv' in fastdep rules.
1661 * Upgrade mdate-sh to work on OS/2.
1662 * Don't byte-compile elisp files when ELCFILES is set empty.

1669 * `make install' will build `BUILT_SOURCES' first.
1670 * Minor documentation fixes.
1672 Bugs fixed in 1.7.3:
1673 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1674 * Query distutils for `pythondir' and `pythonexecdir', instead of
1675 using an hardcoded path. This should allow builds on 64-bit
1676 distributions that usually use lib64/ instead of lib/.
1677 * AM_PATH_PYTHON will also search for python2.3.
1678 * elisp files are now built all at once instead of one by one. Besides
1679 incurring a speed-up, this is required to support interdependent elisp files.
1680 * Support for DJGPP:
1681 - `make distcheck' will now work in `_inst/' and `_build' instead
1682 of `=inst/' and `=build/'
1683 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1684 - install/uninstall `*.i[0-9][0-9]'-style info files
1685 - more changes that affect only the Automake package (not its output)
1686 * Fix some incompatibilities with upcoming perl-5.10.
1687 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1688 PACKAGE and VERSION.
1690 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1691 is troublesome with gcc and Solaris compilers. (PR/385)
1692 - makedepend mode: work with Libtool. (PR/385 too)
1694 * better support for unusual gettext setups, such as multiple po/ directories
1696 - Flag missing po/ and intl/ directories as warnings, not errors.
1697 - Disable these warnings if po/ does not exist.
1698 * Noteworthy manual updates:
1700 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1702 - Document `AM_YFLAGS = -d'. (PR/382)
1704 Bugs fixed in 1.7.2:
1705 * Fix installation and uninstallation of Info files built in subdirectories.
1706 * Do not run `./configure --with-included-gettext' during `make distcheck'
1707 if AM_GNU_GETTEXT([external]) is used.
1708 * Correctly uninstall renamed man pages.
1709 * Do not strip escaped newline in variables defined in one condition
1710 and augmented in another condition.
1711 * Fix ansi2knr rules for LIBOBJS sources.
1712 * Clean all known Texinfo index files, not only those which appear to
1713 be used, because we cannot know which indexes are used in included files.
1714 (PR/375, Debian Bug #168671)
1715 * Honor only the first @setfilename seen in a Texinfo file.
1716 * Treat "required file X not found" diagnostics as errors (exit status 1).
1717 * Don't complain that a required file is not found when it is a Makefile
1719 * Don't use single suffix inference rules when building `.info'-less
1720 Info files, for the sake of Solaris make.
1721 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1722 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1723 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1724 * Fix building of deansified files from subdirectories. (PR/370)
1725 * Add missing `fi' in the .c->.obj rules.
1726 * Improve install-sh to work even when names contain spaces or certain
1727 (but not all) shell metachars.
1728 * Fix the following spurious failures in the test suite:
1729 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1730 * Noteworthy manual updates:
1731 - Augment the section about BUILT_SOURCES.
1732 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1734 Bugs fixed in 1.7.1:
1735 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1737 * Aclocal should now recognize macro names containing parentheses, e.g.
1738 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1739 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1741 * Install Python files even if they were built. (PR/369)
1742 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1743 version might not be defined in the latter. (PR/358)
1744 * Reorder arguments passed to a couple of commands, so things works
1745 when POSIXLY_CORRECT=1.
1746 * Fix a regex that can cause Perl to segfault on large input.
1748 * Fix distribution of packages that have some sources defined conditionally,
1749 as in the `Conditional compilation using Automake conditionals' example
1751 * Fix spurious test suite failures on IRIX.
1752 * Don't report a required variable as undefined if it has been
1753 defined conditionally for the "right" conditions.
1754 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1755 `make distcheck' fails.
1756 * Fix distribution of included Makefile fragment, so we don't create
1757 spurious directories in the distribution. (PR/366)
1758 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1761 * Autoconf 2.54 is required.
1762 * `aclocal' and `automake' will no longer warn about obsolete
1763 configure macros. This is done by `autoconf -Wobsolete'.
1764 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1765 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1766 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1767 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1768 `configure.ac' for you.
1769 * Support for per-program and per-library `_CPPFLAGS'.
1770 * New `ctags' target (builds CTAGS files).
1771 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1772 (see `automake --help' or the manual for a list of them).
1773 * Honor the WARNINGS environment variable.
1774 * Omit the call to depcomp when using gcc3: call the compiler directly.
1775 * A new option, std-options, tests that programs support --help and --version
1776 when `make installcheck' is run. This is enabled by --gnits.
1777 * Texinfo rules now support the `ps' and `pdf' targets.
1778 * Info files are now created in the build directory, not the source directory.
1779 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1781 * `make distcheck' will enforce DESTDIR support by attempting
1783 * `+=' can be used in conditionals, even if the augmented variable
1784 was defined for another condition.
1785 * Makefile fragments (inserted with `include') are always distributed.
1786 * Use Autoconf's --trace interface to inspect configure.ac and get
1787 a more accurate view of it.
1788 * Add support for extending aclocal's default macro search path
1789 using a `dirlist' file within the aclocal directory.
1790 * automake --output-dir is deprecated.
1791 * The part of the distcheck target that checks whether uninstall actually
1792 removes all installed files has been moved in a separate target,
1793 distuninstallcheck, so it can be overridden easily.
1797 * Support for AM_INIT_GETTEXT([external])
1798 * Bug fixes, including:
1799 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1800 - nobase_ programs and scripts honor --program-transform correctly.
1801 - Erase configure.lineno during `make distclean'.
1802 - Erase YACC and LEX outputs during `make maintainer-clean'.
1805 * Many bug fixes, including:
1806 - Requiring the current version works.
1807 - Fix "$@" portability issues (for Zsh).
1808 - Fix output of dummy dependency files in presence of post-processed
1810 - Don't compute dependencies in background to avoid races with libtool.
1811 - Fix handling of _OBJECTS variables for targets sharing source variables.
1812 - Check dependency mode for Java when AM_PROG_GCJ is used.

1816 * Many bug fixes, including:
1817 - Don't choke on AM_LDFLAGS definitions.
1818 - Clean libtool objects from subdirectories.
1819 - Allow configure variables with reserved suffix and unknown prefix
1820 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1821 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1824 * Autoconf 2.52 is required.

1849 (Note that "pkgname" is not "tarname", see the manual for details.)
1850 It is also possible to pass a list of global Automake options as
1851 first argument to this new form of AM_INIT_AUTOMAKE.
1852 * Compiler-based assembler is now called `CCAS'; people expected `AS'
