1 * WARNING: Future backward-incompatibilities!
3 - The following long-obsolete m4 macros will be removed in the
4 next major Automake version (1.13):
6 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
7 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
8 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
9 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
10 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
11 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
12 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
13 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
14 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
15 of the now-removed automatic de-ANSI-fication
18 - All the "old alias" macros in 'm4/obsolete.m4' will be removed in
19 the next major Automake version (1.13).
21 - Support for the two- and three-arguments invocation forms of the
22 AM_INIT_AUTOMAKE macro will be deprecated in the next minor version
23 of Automake (1.12.1) and removed in the next major version (1.13).
25 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
26 variable, @mkdir_p@ substitution and AM_PROG_MKDIR m4 macro will
27 all be deprecated in the next minor version of Automake (1.12.1)
28 and removed in the next major version (1.13).
30 - The '--acdir' option of aclocal is deprecated, and will probably
31 be removed in the next major Automake release (1.13). You should
32 use the options '--automake-acdir' and '--system-acdir' instead
33 (which have been introduced in Automake 1.11.2).
35 - The exact order in which the directories in the aclocal macro
36 search path are looked up is probably going to be changed in the
37 next Automake release (1.13).
41 * Obsolete features removed:
43 - Support for automatic de-ANSI-fication has been removed.
45 - The support for the "obscure" multilib feature has been removed
46 from Automake core (but remains available in the 'contrib/'
47 directory of the Automake distribution).
49 - Support for ".log -> .html" conversion and the check-html and
50 recheck-html targets has been removed from Automake core (but
51 remains available in the 'contrib/' directory of the Automake
54 - The deprecated 'lzma' compression format for distribution archives
55 has been removed, in favor of 'xz' and 'lzip'.
57 - The obsolete AM_WITH_REGEX macro has been removed.
59 - The long-deprecated options '--output-dir', '--Werror' and
60 '--Wno-error' have been removed.
62 - The chapter on the history of Automake has been moved out of the
63 reference manual, into a new dedicated Texinfo file.
67 - New 'cscope' target to build a cscope database for the source tree.
69 * Changes to Automake-generated testsuite harnesses:
71 - The new automake option 'serial-tests' has been introduced. It can
72 be used to explicitly instruct automake to use the older serial
73 testsuite harness. This is still the default at the moment, but it
74 might change in future versions.
76 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
77 and unexpected or internal error, or a failure to set up the test case
78 scenario) have their outcome reported as an 'ERROR' now. Previous
79 versions of automake reported such an outcome as a 'FAIL' (the only
80 difference with normal failures being that hard errors were counted
81 as failures even when the test originating them was listed in
84 - The testsuite summary displayed by the parallel-test harness has a
85 completely new format, that always list the numbers of passed, failed,
86 xfailed, xpassed, skipped and errored tests, even when these numbers
87 are zero (but using smart coloring when the color-tests option is in
90 - The default testsuite driver offered by the 'parallel-tests' option is
91 now implemented (partly at least) with the help of automake-provided
92 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
93 on code in the generated Makefile.in.
94 This has two noteworthy implications. The first one is that projects
95 using the 'parallel-tests' option should now either run automake with
96 the '--add-missing' option, or manually copy the 'test-driver' script
97 into their tree. The second, and more important, implication is that
98 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
99 not be used anymore to define a test runner, and the command specified
100 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
101 program or script. For example, this is still a valid usage (albeit
104 TESTS_ENVIRONMENT = \
105 if test -n '$(STRICT_TESTS)'; then \
106 maybe_errexit='-e'; \
110 LOG_COMPILER = $(SHELL) $$maybe_errexit
112 while this is not anymore:
114 TESTS_ENVIRONMENT = \
115 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
119 TESTS_ENVIRONMENT = \
120 run_with_perl_or_shell () \
122 if grep -q '^#!.*perl' $$1; then
128 LOG_COMPILER = run_with_per_or_shell
130 - The package authors can now use customary testsuite drivers within
131 the framework provided by the 'parallel-tests' testsuite harness.
132 Consistently with the existing syntax, this can be done by defining
133 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
135 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
136 to redirect/define file descriptors used by the test scripts.
138 - The parallel-tests harness generates now, in addition the '.log' files
139 holding the output produced by the test scripts, a new set of '.trs'
140 files, holding "metadata" derived by the execution of the test scripts;
141 among such metadata are the outcomes of the test cases run by a script.
143 - Initial and still experimental support for the TAP test protocol is
146 * Changes to Yacc and Lex support:
148 - C source and header files derived from non-distributed Yacc and/or
149 Lex sources are now removed by a simple "make clean" (while they were
150 previously removed only by "make maintainer-clean").
152 - Slightly backward-incompatible change, relevant only for use of Yacc
153 with C++: the extensions of the header files produced by the Yacc
154 rules are now modelled after the extension of the corresponding
155 sources. For example, yacc files named "foo.y++" and "bar.yy" will
156 produce header files named "foo.h++" and "bar.hh" respectively, where
157 they would have previously produced header files named simply "foo.h"
158 and "bar.h". This change offers better compatibility with 'bison -o'.
160 * Miscellaneous changes:
162 - Automake now prefers to quote 'like this' or "like this", rather
163 than `like this', in diagnostic message and generated Makefiles,
164 to accommodate the new GNU Coding Standards recommendations.
166 - Automake has a new option '--print-libdir' that prints the path of the
167 directory containing the Automake-provided scripts and data files.
169 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
171 - Automake can now generate silenced rules for texinfo outputs.
173 - Some auxiliary files that are automatically distributed by Automake
174 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
175 C sources) might now be listed in the DIST_COMMON variable in many
176 Makefile.in files, rather than in the top-level one.
178 - Messages of types warning or error from 'automake' and 'aclocal'
179 are now prefixed with the respective type, and presence of -Werror
182 - Automake's early configure-time sanity check now tries to avoid
183 sleeping for a second, which slowed down cached configure runs
184 noticeably. In that case, it will check back at the end of the
185 configure script to ensure that at least one second has passed, to
186 avoid time stamp issues with makefile rules rerunning autotools
189 - For programs and libraries, automake now detect EXTRA_foo_DEPENDENCIES
190 and adds them to the normal list of dependencies, but without
191 overwriting the foo_DEPENDENCIES variable, which is normally computed
194 - The warnings in the category 'extra-portability' are now enabled by
195 '-Wall'. In previous versions, one has to use '-Wextra-portability'
200 - Various minor bugfixes for recent or long-standing bugs.
202 * Bugs introduced by 1.11:
204 - The AM_COND_IF macro also works if the shell expression for the
205 conditional is no longer valid for the condition.
207 - The automake-provided parallel testsuite harness does not fail anymore
208 with BSD make used in parallel mode when there are test scripts in a
209 subdirectory, like in:
211 TESTS = sub/foo.test sub/bar.test
213 * Long-standing bugs:
215 - Automake's own build system finally have a real "installcheck" target.
217 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
218 now automatically distributed also if the directory of the auxiliary
219 files coincides with the top-level directory.
221 - Automake now detects the presence of the '-d' flag in the various
222 '*YFLAGS' variables even when their definitions involve indirections
223 through other variables, such as in:
225 AM_YFLAGS = $(foo_opts)
227 - Automake now complains if a '*YFLAGS' variable has any conditional
228 content, not only a conditional definition.
230 - Explicit enabling and/or disabling of Automake warning categories
231 through the '-W...' options now always takes precedence over the
232 implicit warning level implied by Automake strictness (foreign, gnu
233 or gnits), regardless of the order in which such strictness and
234 warning flags appear. For example, a setting like:
235 AUTOMAKE_OPTIONS = -Wall --foreign
236 will cause the warnings in category 'portability' to be enabled, even
237 if those warnings are by default disabled in 'foreign' strictness.
239 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
243 * WARNING: Future backward-incompatibilities!
245 - The obsolescent AM_WITH_REGEX macro has been deprecated, since the
246 GNU rx library has been decommissioned.
248 - The `lzma' compression format for distribution archives has been
249 deprecated in favor of `xz' and `lzip'.
251 * Miscellaneous changes:
253 - Automake's own build system is more silent by default, making use of
254 the 'silent-rules' option.
256 - The master copy of the `gnupload' script is now maintained in gnulib,
259 - The `missing' script doesn't try to wrap calls to `tar' anymore.
261 - "make dist" doesn't wrap `tar' invocations with the `missing' script
262 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
263 shouldn't be using BTW ;-) does not invoke the missing script anymore
264 to wrap tar, but simply invokes the `tar' program itself.
266 - "make dist" can now create lzip-compressed tarballs.
268 - In the Automake info documentation, the Top node and the nodes about
269 the invocation of the automake and aclocal programs have been renamed;
270 now, calling "info automake" will open the Top node, while calling
271 "info automake-invocation" and "info aclocal-invocation" will access
272 the nodes about the invocation of respectively automake and aclocal.
274 - Automake is now distributed as a gzip-compressed and an xz-compressed
275 tarball. Previously, bzip2 was used instead of xz.
277 - The last relics of Python 1.5 support have been removed from the
278 AM_PATH_PYTHON macro.
280 Bugs fixed in 1.11.3:
282 * Long-standing bugs:
284 - The "deleted header file problem" for *.am files is avoided by stub
285 rules. This allows `make' to trigger a rerun of `automake' also if
286 some previously needed `.am' file has been removed.
288 - The `silent-rules' option now generates working makefiles even
289 for the uncommon `make' implementations that do not support the
290 nested-variables extension to POSIX 2008. For such `make'
291 implementations, whether a build is silent is determined at
292 configure time, and cannot be overridden at make time with
293 `make V=0' or `make V=1'.
295 - Vala support now works better in VPATH setups.
297 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
301 * Changes to aclocal:
303 - The `--acdir' option is deprecated. Now you should use the new options
304 `--automake-acdir' and `--system-acdir' instead.
306 - The `ACLOCAL_PATH' environment variable is now interpreted as a
307 colon-separated list of additional directories to search after the
308 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
309 and before the system acdir (by default ${prefix}/share/aclocal).
311 * Miscellaneous changes:
313 - The Automake support for automatic de-ANSI-fication has been
316 - The `lzma' compression scheme and associated automake option `dist-lzma'
317 is obsoleted by `xz' and `dist-xz' due to upstream changes.
319 - You may adjust the compression options used in dist-xz and dist-bzip2.
320 The default is now merely -e for xz, but still -9 for bzip; you may
321 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
322 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
324 - The `compile' script now converts some options for MSVC for a better
325 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
327 - The py-compile script now accepts empty arguments passed to the options
328 `--destdir' and `--basedir', and complains about unrecognized options.
329 Moreover, a non-option argument or a special `--' argument terminates
332 - A developer that needs to pass specific flags to configure at "make
333 distcheck" time can now, and indeed is advised to, do so by defining
334 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
335 instead of the old DISTCHECK_CONFIGURE_FLAGS.
336 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
337 user; still, the old Makefile.am files that used to define it will
338 still continue to work as before.
340 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
341 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
342 This new macro is required for LIBRARIES and LTLIBRARIES when automake
343 is run with -Wextra-portability and -Werror.
345 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
346 file generated by automake-provided rules by defining the special make
347 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
349 - The `install-info' rule can now be instructed not to create/update
350 the `${infodir}/dir' file, by exporting the new environment variable
351 `AM_UPDATE_INFO_DIR' to the value "no".
353 Bugs fixed in 1.11.2:
355 * Bugs introduced by 1.11.2:
357 - Automake now correctly recognizes the prefix/primary combination
358 `pkglibexec_SCRIPTS' as valid.
360 * Bugs introduced by 1.11:
362 - The parallel-tests driver no longer produces erroneous results with
363 Tru64/OSF 5.1 sh upon unreadable log files.
365 - The `parallel-tests' test driver does not report spurious successes
366 when used with concurrent FreeBSD make (e.g., "make check -j3").
368 - When the parallel-tests driver is in use, automake now explicitly
369 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
370 instead of issuing confusing and apparently unrelated error messages
371 (e.g., "non-POSIX variable name", "bad characters in variable name",
372 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
373 silently producing broken `Makefile.in' files.
375 - The `silent-rules' option now truly silences all compile rules, even
376 when dependency tracking is disabled. Also, when `silent-rules' is
377 not used, `make' output no longer contains spurious backslash-only
378 lines, thus once again matching what Automake did before 1.11.
380 - The AM_COND_IF macro also works if the shell expression for the
381 conditional is no longer valid for the condition.
383 * Long-standing bugs:
385 - The order of Yacc and Lex flags is fixed to be consistent with other
386 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
387 $(LFLAGS), so that the user variables override the developer variables.
389 - "make distcheck" now correctly complains also when "make uninstall"
390 leaves one and only one file installed in $(prefix).
392 - A "make uninstall" issued before a "make install", or after a mere
393 "make install-data" or a mere "make install-exec" does not spuriously
396 - Automake now warns about more primary/directory invalid combinations,
397 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
399 - Rules generated by Automake now try harder to not change any files when
400 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
401 Yacc source files and the rule to update config.h.
403 - Several scripts and the parallel-tests testsuite driver now exit with
404 the right exit status upon receiving a signal.
406 - A per-Makefile.am setting of -Werror does not erroneously carry over
407 to the handling of other Makefile.am files.
409 - The code for automatic dependency tracking works around a Solaris
410 make bug triggered by sources containing repeated slashes when the
411 `subdir-objects' option was used.
413 - The makedepend and hp depmodes now work better with VPATH builds.
415 - Java sources specified with check_JAVA are no longer compiled for
416 "make all", but only for "make check".
418 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
419 and error out if `javadir' is undefined, instead of silently producing
420 a broken Makefile.in.
422 - aclocal and automake now honour the configure-time definitions of
423 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
425 - The `install-info' recipe no longer tries to guess whether the
426 `install-info' program is from Debian or from GNU, and adaptively
427 change its behaviour; this has proven to be frail and easy to
430 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
432 Bugs fixed in 1.11.1:
434 - Lots of minor bugfixes.
436 * Bugs introduced by 1.11:
438 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
439 trailing white space in the test list (`TESTS = foo $(EMPTY)').
441 * Long standing bugs:
443 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
444 even if the `--prefix' argument pointed outside of a system directory.
445 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
446 `get_python_lib' function if it points outside the configured prefix,
447 unless the `--prefix' argument was either `/usr' or below `/System'.
449 - The testsuite does not try to change the mode of `ltmain.sh' files from
450 a Libtool installation (symlinked to test directories) any more.
452 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
453 tools are preferred in a cross-compile setup.
455 - The distribution is tarred up with mode 755 now by the `dist*' targets.
456 This fixes a race condition where untrusted users could modify files
457 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
458 build directory was world-searchable. This is CVE-2009-4029.
460 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
464 * Version requirements:
466 - Autoconf 2.62 or greater is required.
468 * Changes to aclocal:
470 - The autoconf version check implemented by aclocal in aclocal.m4
471 (and new in Automake 1.10) is degraded to a warning. This helps
472 in the common case where the Autoconf versions used are compatible.
474 * Changes to automake:
476 - The automake program can run multiple threads for creating most
477 Makefile.in files concurrently, if at least Perl 5.7.2 is available
478 with interpreter-based threads enabled. Set the environment variable
479 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
480 enable this experimental feature.
482 * Changes to Libtool support:
484 - Libtool generic flags are now passed to the install and uninstall
487 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
488 config.lt is removed correctly now.
492 - subdir-object mode works now with Fortran (F77, FC, preprocessed
493 Fortran, and Ratfor).
495 - For files with extension .f90, .f95, .f03, or .f08, the flag
496 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
498 - Files with extension .sx are also treated as preprocessed assembler.
500 - The default source file extension (.c) can be overridden with
501 AM_DEFAULT_SOURCE_EXT now.
503 - Python 3.0 is supported now, Python releases prior to 2.0 are no
506 - AM_PATH_PYTHON honors python's idea about the site directory.
508 - There is initial support for the Vala programming language, when using
511 * Miscellaneous changes:
513 - Automake development is done in a git repository on Savannah now, see
515 http://git.sv.gnu.org/gitweb/?p=automake.git
517 A read-only CVS mirror is provided at
519 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
520 checkout -d automake HEAD
522 - "make dist" can now create xz-compressed tarballs,
523 as well as (deprecated?) lzma-compressed tarballs.
525 - `automake --add-missing' will by default install the GPLv3 file as
526 COPYING if it is missing. It will also warn that the license file
527 should be added to source control. Note that Automake will never
528 overwrite an existing COPYING file, even when the `--force-missing'
531 - The manual is now distributed under the terms of the GNU FDL 1.3.
533 - Automake ships and installs man pages for automake and aclocal now.
535 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
537 - install-sh supports -C, which does not update the installed file
538 (and its time stamps) if the contents did not change.
540 - The `gnupload' script has been revamped.
542 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
544 - The targets `install' and `uninstall' are more efficient now, in that
545 for example multiple files from one Automake variable such as
546 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
547 invocation if they do not have to be renamed.
549 Both install and uninstall may sometimes enter (`cd' into) the target
550 installation directory now, when no build-local scripts are used.
552 Both install and uninstall do not fail anymore but do nothing if an
553 installation directory variable like `bindir' is set to the empty string.
555 For built-in rules, `make install' now fails reliably if installation
556 of a file failed. Conversely, `make uninstall' even succeeds when
557 issued multiple times.
559 These changes may need some adjustments from users: For example,
560 some `install' programs refuse to install multiple copies of the
561 same file in one invocation, so you may need to remove duplicate
562 entries from file lists.
564 Also, within one set of files, say, nobase_data_DATA, the order of
565 installation may be changed, or even unstable among different hosts,
566 due to the use of associative arrays in awk. The increased use of
567 awk matches a similar move in Autoconf to provide for better scaling.
569 Further, most undocumented per-rule install command variables such as
570 binSCRIPT_INSTALL have been removed because they are not needed any
571 more. Packages which use them should be using the appropriate one of
572 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
573 counterpart, depending on the type of files and the need for automatic
574 target directory creation.
576 - The "deleted header file problem" for *.m4 files is avoided by
577 stub rules. This allows `make' to trigger a rerun of `aclocal'
578 also if some previously needed macro file has been removed.
580 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
581 an otherwise up to date tree.
583 - The `color-tests' option causes colored test result output on terminals.
585 - The `parallel-tests' option enables a new test driver that allows for
586 parallel test execution, inter-test dependencies, lazy test execution
587 for unit-testing, re-testing only failed tests, and formatted result output
588 as RST (reStructuredText) and HTML. Enabling this option may require some
589 changes to your test suite setup; see the manual for details.
591 - The `silent-rules' option enables Linux kernel-style silent build output.
592 This option requires the widely supported but non-POSIX `make' feature
593 of recursive variable expansion, so do not use it if your package needs
594 to build with `make' implementations that do not support it.
596 To enable less verbose build output, the developer has to use the Automake
597 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
598 macro. The user may then set the default verbosity by passing the
599 `--enable-silent-rules' option to `configure'. At `make' run time, this
600 default may be overridden using `make V=0' for less verbose, and `make V=1'
601 for backward-compatible verbose output.
603 - New prefix `notrans_' for manpages which should not be transformed
604 by --program-transform.
606 - New macro AM_COND_IF for conditional evaluation and conditional
609 - For AC_CONFIG_LINKS, if source and destination are equal, do not
610 remove the file in a non-VPATH build. Such setups work with Autoconf
613 - AM_MAINTAINER_MODE now allows for an optional argument specifying
616 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
617 useful especially for multi-line values.
619 - Automake's early configure-time sanity check now diagnoses an
620 unsafe absolute source directory name and makes configure fail.
622 - The Automake macros and rules cope better with whitespace in the
623 current directory name, as long as the relative path to `configure'
624 does not contain whitespace. To this end, the values of `$(MISSING)'
625 and `$(install_sh)' may contain suitable quoting, and their expansion
626 might need `eval'uation if used outside of a makefile. These
627 undocumented variables may be used in several documented macros such
628 as $(AUTOCONF) or $(MAKEINFO).
632 * Long-standing bugs:
634 - Fix aix dependency tracking for libtool objects.
636 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
637 unnecessary use of the `compile' script.
639 - For nobase_*_LTLIBRARIES with nonempty directory components, the
640 correct `-rpath' argument is used now.
642 - `config.status --file=Makefile depfiles' now also works with the
643 extra quoting used internally by Autoconf 2.62 and newer
644 (it used to work only without the `--file=' bit).
646 - The `missing' script works better with versioned tool names.
648 - Semantics for `missing help2man' have been revamped:
650 Previously, if `help2man' was not present, `missing help2man' would have
651 the following semantics: if some man page was out of date but present, then
652 a warning would be printed, but the exit status was 0. If the man page was
653 not present at all, then `missing' would create a replacement man page
654 containing an error message, and exit with a status of 2. This does not play
655 well with `make': the next run will see this particular man page as being up
656 to date, and will only error out on the next generated man page, if any;
657 repeat until all pages are done. This was not desirable.
659 These are the new semantics: if some man page is not present, and help2man
660 is not either, then `missing' will warn and generate the replacement page
661 containing the error message, but exit successfully. However, `make dist'
662 will ensure that no such bogus man pages are packaged into a tarball.
664 - Targets provided by automake behave better with `make -n', in that they
665 take care not to create files.
667 - `config.status Makefile... depfiles' works fine again in the presence of
668 disabled dependency tracking.
670 - The default no-op recursive rules for these targets also work with BSD make
671 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
673 - `make distcheck' works also when both a directory and some file below it
674 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
676 - Texinfo dvi, ps, pdf, and html output files are not removed upon
677 `make mostlyclean' any more; only the LaTeX by-products are.
679 - Renamed objects also work with the `subdir-objects' option and
680 source file languages which Automake does not know itself.
682 - `automake' now correctly complains about variable assignments which are
683 preceded by a comment, extend over multiple lines with backslash-escaped
684 newlines, and end in a comment sign. Previous versions would silently
685 and wrongly ignore such assignments completely.
687 * Bugs introduced by 1.10:
689 - Fix output of dummy dependency files in presence of post-processed
690 Makefile.in's again, but also cope with long lines.
692 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
693 that have been declared as programs in the same Makefile.
694 This is for consistency with the analogous change to TESTS in 1.10.
696 - Fix order of standard includes to again be `-I. -I$(srcdir)',
697 followed by directories containing config headers.
699 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
703 * Version requirements:
705 - Autoconf 2.60 or greater is required.
707 - Perl 5.6 or greater is required.
709 * Changes to aclocal:
711 - aclocal now also supports -Wmumble and -Wno-mumble options.
713 - `dirlist' entries (for the aclocal search path) may use shell
714 wildcards such as `*', `?', or `[...]'.
716 - aclocal supports an --install option that will cause system-wide
717 third-party macros to be installed in the local directory
718 specified with the first -I flag. This option also uses #serial
719 lines in M4 files to upgrade local macros.
721 The new aclocal options --dry-run and --diff help to review changes
722 before they are installed.
724 - aclocal now outputs an autoconf version check in aclocal.m4 in
725 projects using automake.
727 For a few years, automake and aclocal have been calling autoconf
728 (or its underlying engine autom4te) to accurately retrieve the
729 data they need from configure.ac and its siblings. Doing so can
730 only work if all autotools use the same version of autoconf. For
731 instance a Makefile.in generated by automake for one version of
732 autoconf may stop working if configure is regenerated with another
733 version of autoconf, and vice versa.
735 This new version check ensures that the whole build system has
736 been generated using the same autoconf version.
738 * Support for new Autoconf macros:
740 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
742 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
743 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
744 in different directories. However, only one instance of such a
745 library objects directory is supported.
747 * Change to Libtool support:
749 - Libtool generic flags (those that go before the --mode=MODE option)
750 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
752 * Yacc and Lex changes:
754 - The rebuild rules for distributed Yacc and Lex output will avoid
755 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
758 - ylwrap is now always used for lex and yacc source files,
759 regardless of whether there is more than one source per directory.
763 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
764 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
765 tracking, unlike non-preprocessed assembler (*.s).
767 - subdir-object mode works now with Assembler. Automake assumes
768 that the compiler understands `-c -o'.
770 - Preprocessed assembler (*.S) compilation now also honors
771 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
773 - Improved support for Objective C:
774 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
775 - A new section of the manual documents the support.
777 - New support for Unified Parallel C:
778 - AM_PROG_UPC looks for a UPC compiler.
779 - A new section of the manual documents the support.
781 - Per-target flags are now correctly handled in link rules.
783 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
784 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
785 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
786 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
788 The fix for compiler flags (i.e., using maude_CFLAGS instead of
789 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
790 is expected to work (and actually works during compilation).
792 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
793 "in addition to" breaks backward compatibility with older versions.
794 If your package used both variables, as in
796 AM_LDFLAGS = common flags
798 a_LDFLAGS = more flags
801 and assumed *_LDFLAGS would sum up, you should rewrite it as
803 AM_LDFLAGS = common flags
805 a_LDFLAGS = $(AM_LDFLAGS) more flags
808 This new behavior of *_LDFLAGS is more coherent with other
809 per-target variables, and the way *_LDFLAGS variables were
810 considered internally.
812 * New installation targets:
814 - New targets mandated by GNU Coding Standards:
819 By default they will only install Texinfo manuals.
820 You can customize them with *-local variants:
826 - The undocumented recursive target `uninstall-info' no longer exists.
827 (`uninstall' is in charge of removing all possible documentation
828 flavors, including optional formats such as dvi, ps, or info even
829 when `no-installinfo' is used.)
831 * Miscellaneous changes:
833 - Automake no longer complains if input files for AC_CONFIG_FILES
834 are specified using shell variables.
836 - clean, distribution, or rebuild rules are normally disabled for
837 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
838 AC_CONFIG_LINK specified using shell variables. However, if these
839 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
840 be able to output rules anyway.
841 (See the Automake documentation for AC_CONFIG_FILES.)
843 - $(EXEEXT) is automatically appended to filenames of TESTS
844 that have been declared as programs in the same Makefile.
845 This is mostly useful when some check_PROGRAMS are listed in TESTS.
847 - `-Wportability' has finally been turned on by default for `gnu' and
848 `gnits' strictness. This means, automake will complain about %-rules
849 or $(GNU Make functions) unless you switch to `foreign' strictness or
850 use `-Wno-portability'.
852 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
853 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
854 $(mkdir_p) variable is still defined (to the same value as
855 $(MKDIR_P)) but should be considered obsolete. If you are using
856 $(mkdir_p) in some of your rules, please plan to update them to
857 $(MKDIR_P) at some point.
859 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
860 They still work in this release, but may be withdrawn in a future one.
862 - Inline compilation rules for gcc3-style dependency tracking are
865 - Automake installs a "Hello World!" example package in $(docdir).
866 This example is used throughout the new "Autotools Introduction"
867 chapter of the manual.
869 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
873 * Makefile.in bloat reduction:
875 - Inference rules are used to compile sources in subdirectories when
876 the `subdir-objects' option is used and no per-target flags are
877 used. This should reduce the size of some projects a lot, because
878 Automake used to output an explicit rule for each such object in
881 - Automake no longer outputs three rules (.o, .obj, .lo) for each
882 object that must be built with explicit rules. It just outputs
883 the rules required to build the kind of object considered: either
884 the two .o and .obj rules for usual objects, or the .lo rule for
887 * Change to Libtool support:
889 - Libtool tags are used with libtool versions that support them.
890 (I.e., with Libtool 1.5 or greater.)
892 - Automake is now able to handle setups where a libtool library is
893 conditionally installed in different directories, as in
896 lib_LTLIBRARIES = liba.la
898 pkglib_LTLIBRARIES = liba.la
900 liba_la_SOURCES = ...
902 * Changes to aclocal:
904 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
905 really evaluated, before it decides to include them in aclocal.m4.
906 This solves nasty problems with conditional redefinitions of
907 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
908 *.m4 files to be included in any project using these macros.
909 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
910 most famous instance of this bug.)
912 - Do not complain about missing conditionally AC_REQUIREd macros
913 that are not actually used. In 1.8.x aclocal would correctly
914 determine which of these macros were really needed (and include
915 only these in the package); unfortunately it would also require
916 all of them to be present in order to run. This created
917 situations were aclocal would not work on a tarball distributing
918 all the macros it uses. For instance running aclocal on a project
919 containing only the subset of the Gettext macros in use by the
920 project did not work, because gettext conditionally requires other
923 * Portability improvements:
925 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
926 tar-pax. The new option filename-length-max=99 helps diagnosing
927 filenames that are too long for tar-v7. (PR/414)
929 - Variables aumented with `+=' are now automatically flattened (i.e.,
930 trailing backslashes removed) and then wrapped around 80 colummns
931 (adding trailing backslashes). In previous versions, a long series
937 would result in a single-line definition of VAR that could possibly
938 exceed the maximum line length of some make implementations.
940 Non-augmented variables are still output as they are defined in
945 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
946 Works the same as the old Fortran 77 implementation; just replace
947 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
948 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
950 - Support for conditional _LISP.
952 - Support for conditional -hook and -local rules (PR/428).
954 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
956 - Automake will not write any Makefile.ins after the first error it
957 encounters. The previous Makefile.ins (if any) will be left in
958 place. (Warnings will not prevent output, but remember they can
959 be turned into errors with -Werror.)
961 - The restriction that SUBDIRS must contain direct children is gone.
964 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
965 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
967 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
971 * Long-standing bugs:
973 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
974 so that `make distclean' and `make maintainer-clean' can work.
976 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
978 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
980 - Polish diagnostic when no input file is found.
982 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
986 * Long-standing bugs:
988 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
989 overridden by the user.
991 - Honor PATH_SEPARATOR in various places of the Automake package, for
994 - Adjust dependency tracking mode detection to ICC 8.0's new output.
997 - Fix install-sh so it can install the `mv' binary... using `mv'.
999 - Fix tru64 dependency tracking for libtool objects.
1001 - Work around Exuberant Ctags when creating a TAGS files in a directory
1002 without files to scan but with subdirectories to include.
1004 * Bugs introduced by 1.8:
1006 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1007 not defined in the same conditions as the _LDADD that uses it.
1009 - Do not warn when JAVAROOT is overridden, this is legitimate.
1011 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1013 Bugs fixed in 1.8.3:
1015 * Long-standing bugs:
1017 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1018 or any of the other *dir variables contain a space.
1020 Please note that Automake does not and cannot support spaces in
1021 filenames that are involved during the build. This change affects
1022 only installation paths, so that `make install' does not bomb out
1023 in packages configured with
1024 ./configure --prefix '/c/Program Files'
1026 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1027 POSIXLY_CORRECT is set.
1029 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1030 since Autoconf 2.54, which defines LIBOBJS itself.
1032 - Fix a potential (but unlikely) race condition in parallel elisp
1033 builds. (Introduced in 1.7.3.)
1035 - Do not assume that users override _DEPENDENCIES in all conditions
1036 where Automake will try to define them.
1038 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1039 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1042 This fix also affects the $(mkdir_p) variable defined since
1043 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1044 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1046 - Secure temporary directory creation in `make distcheck'. (PR/413)
1048 - Do not generate two build rules for `parser.h' when the
1049 parser appears in two different conditionals.
1051 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1052 checking. Usually ./configure will not pick this shell; so this
1053 fix only helps cases where the shell is forced to /bin/sh.
1055 * Bugs introduced by 1.8:
1057 - In some situations (hand-written `m4_include's), aclocal would
1058 call the `File::Spec->rel2abs' method, which was only introduced
1059 in Perl 5.6. This new version reestablish support Perl 5.005.
1061 It is likely that the next major Automake releases will require at
1062 least Perl 5.6. Consider upgrading your development environment
1063 if you are still using the five-year-old Perl 5.005.
1065 - Automake would sometimes fail to define rules for targets listed
1066 in variables defined in multiple conditions. For instance on
1072 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1073 `b.$(OBJEXT): b.c' rule.
1075 * New sections in manual:
1077 - Third-Party Makefiles: how to interface third party Makefiles.
1078 - Upgrading: upgrading packages to newer Automake versions.
1079 - Multiple Outputs: handling tools that produce many outputs.
1081 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1085 * A (well known) portability bug slipped in the changes made to
1086 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1087 install anything on Tru64.
1089 * Fix install rules for conditionally built python files. (This never
1092 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1096 * Bugs introduced by 1.8:
1098 - Fix Config.pm import error with old Perl versions (at least
1099 5.005_03). One symptom is that aclocal could not find its macro
1102 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1103 created by `make install' are always world readable, even if the
1104 installer happens to have an overly restrictive umask (e.g. 077).
1105 This was a mistake and has been reverted. There are at least two
1106 reasons why we must not use `-m 0755':
1107 - it causes special bits like SGID to be ignored,
1108 - it may be too restrictive (some setups expect 775 directories).
1110 - Fix aclocal to honor definitions located in files which have been
1111 m4_included manually. aclocal 1.8 had been updated to check
1112 m4_included files for new requirements, but forgot that these
1113 m4_included files can also provide new definitions.
1115 Note that if you have such a setup, we recommend you get rid of
1116 it. In the past, there was a reason to m4_include files manually:
1117 aclocal used to duplicate entire M4 files into aclocal.m4, even
1118 files that were distributed. Some packages were therefore
1119 m4_including the distributed file directly, and playing some
1120 tricks to ensure aclocal would not copy that file to aclocal.m4,
1121 in order to limit the amount of duplication. Since aclocal 1.8.x
1122 will precisely output m4_includes for local M4 files, we recommend
1123 that you clean up your setup, removing all manual m4_includes and
1124 letting aclocal output them.
1126 - Output detailed menus in the Info version if the Automake manual,
1127 so that Emacs can locate the indexes.
1129 - configure.ac and configure were listed twice in DIST_COMMON (an
1130 internal variable where Automake lists configury files to
1131 distribute). This was harmless, but unaesthetic.
1133 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1134 This was an issue only in the Automake package itself, not in
1137 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1138 DEST:SRC. This was wrong, as some packages do
1139 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1142 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1143 argument. This caused two kinds of failures:
1144 - Rules installing data in a conditionally defined directory
1145 failed when that directory was undefined. In this case no
1146 argument was supplied.
1147 - `make installdirs' failed, because several directories were
1148 passed to $(mkdir_p). This was an issue only on platform
1149 were $(mkdir_p) is implemented with `install-sh -d'.
1150 $(mkdir_p) as been changed to accept 0 or more arguments, as
1153 * Long-standing bugs:
1155 - Fix an unexpected diagnostic occurring when users attempt
1156 to override some internal variables that Automake appends to.
1158 - aclocal now scans configure.ac for macro definitions (PR/319).
1160 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1161 distributes files which are outside itself (this usually occurs
1162 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1163 from a parent package), then `make distcheck' fails due to an
1164 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1165 (tests/subpkg2.test failure)
1167 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1168 In a VPATH-build configuration, `make install' would install
1169 nobase_ files to wrong locations.
1171 - Fix a Perl `uninitialized value' diagnostic occurring when
1172 automake complains that a Texinfo file does not have a
1173 @setfilename statement.
1175 - Erase config.status.lineno during `make distclean'. This file
1176 can be created by config.status. Automake already knew about
1177 configure.lineno, but forgot config.status.lineno.
1179 - Distribute all files, even those which are built and installed
1180 conditionally. This change affects files listed in conditionally
1181 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1182 as well as those listed in conditionally defined dist_*_DATA,
1183 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1185 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1186 doesn't conform to POSIX.
1188 - Normalize help strings for configure variables and options added
1193 - Check for python2.4 in AM_PATH_PYTHON.
1195 * Spurious failures in test suite:
1197 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1198 tests/ltconv.test: fix failures with CVS Libtool.
1199 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1200 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1201 fix failures with old Texinfo versions.
1203 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1209 - The NEWS file is more verbose.
1213 - Autoconf 2.58 or greater is required.
1217 - Default source file names in the absence of a _SOURCES declaration
1218 are made by removing any target extension before appending `.c', so
1219 to make the libtool module `foo.la' from `foo.c', you only need to
1222 lib_LTLIBRARIES = foo.la
1223 foo_la_LDFLAGS = -module
1225 For backward compatibility, foo_la.c will be used instead of
1226 foo.c if this file exists or is the explicit target of a rule.
1227 However -Wobsolete will warn about this deprecated naming.
1229 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1230 of being hard-coded in each $(AR) invocation, so they can be
1231 substituted from configure.ac. This has been requested by people
1232 dealing with non-POSIX ar implementations.
1234 - New warning option: -Woverride. This will warn about any user
1235 target or variable definitions which override Automake
1238 - Texinfo rules back up and restore info files when makeinfo fails.
1240 - Texinfo rules now support the `html' target.
1241 Running this requires Texinfo 4.0 or greater.
1243 `html' is a new recursive target, so if your package mixes
1244 hand-crafted `Makefile.in's with Automake-generated
1245 `Makefile.in's, you should adjust the former to support (or
1246 ignore) this target so that `make html' recurses successfully. If
1247 you had a custom `html' rule in your `Makefile.am', it's better to
1248 rename it as `html-local', otherwise your rule will override
1249 Automake's new rule (you can check that by running `automake
1250 -Woverride') and that will stop the recursion to subdirectories.
1252 Last but not least, this `html' rule is declared PHONY, even when
1253 overridden. Fortunately, it appears that few packages use a
1254 non-PHONY `html' rule.
1256 - Any file which is m4_included from configure.ac will appear as a
1257 configure and Makefile.in dependency, and will be automatically
1260 - The rules for rebuilding Makefiles and Makefile.ins will now
1261 rebuild all Makefiles and all Makefile.ins at once when one of
1262 configure's dependencies has changed. This is considerably faster
1263 than previous implementations, where config.status and automake
1264 were run separately in each directory (this still happens when you
1265 change a Makefile.am locally, without touching configure.ac or
1266 friends). Doing this also solves a longstanding issue: these
1267 rebuild rules failed to work when adding new directories to the
1268 tree, forcing you to run automake manually.
1270 - For similar reasons, the rules to rebuild configure,
1271 config.status, and aclocal.m4 are now defined in all directories.
1272 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1273 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1274 should better define them in all directories. This is easily done
1275 using an AC_SUBST (make sure you prefix these dependencies with
1276 $(top_srcdir) since this variable will appear at different
1277 levels of the build tree).
1279 - aclocal will now use `m4_include' instead of copying local m4
1280 files into aclocal.m4. (Local m4 files are those you ship with
1281 your project, other files will be copied as usual.)
1283 Because m4_included files are automatically distributed, it means
1284 for most projects there is no point in EXTRA_DISTing the list of
1285 m4 files which are used. (You can probably get rid of
1286 m4/Makefile.am if you had one.)
1288 - aclocal will avoid touching aclocal.m4 when possible, so that
1289 Autom4te's cache isn't needlessly invalidated. This behavior can
1290 be switched off with the new `--force' option.
1292 - aclocal now uses Autoconf's --trace to detect macros which are
1293 actually used and will no longer include unused macros simply
1294 because they where mentioned. This was often the case for macros
1295 called conditionally.
1297 - New options no-dist and no-dist-gzip.
1299 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1300 py-compile, and ylwrap, now all understand --version and --help.
1302 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1303 links as part of the distclean target and including source files in
1306 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1307 argument. The latter can be used to override the default behavior
1308 (which is to abort).
1310 - Automake will exit with $? = 63 on version mismatch. (So does
1311 Autoconf 2.58) missing knows this, and in this case it will
1312 emulate the tools as if they were absent. Because older versions
1313 of Automake and Autoconf did not use this exit code, this change
1314 will only be useful in projects generated with future versions of
1317 - When using AC_CONFIG_FILES with multiple input files, Automake
1318 generates the first ".in" input file for which a ".am" exists.
1319 (Former versions would try to use only the first input file.)
1321 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1322 idiom to disable byte-compilation of lisp_LISP files, it is
1323 recommended that you switch to using lisp_DATA. Note that
1324 this is not strictly equivalent: lisp_DATA will install elisp
1325 files even if emacs is not installed, while *_LISP do not
1326 install anything unless emacs is found.
1328 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1329 available. This selection is achieved through the Makefile
1330 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1331 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1332 `$(install_sh) -m 0755 -d'.
1336 - Because `mkdir -p' is available on most platforms, and we can use
1337 `install-sh -d' when it is not, the use of the mkinstalldirs
1338 script is being phased out. `automake --add-missing' no longer
1339 installs it, and if you remove mkinstalldirs from your package,
1340 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1342 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1343 gettextize and autopoint will install it when needed. Automake
1344 will continue to define the $(mkinstalldirs) and to distribute
1345 mkinstalldirs when this script is in the source tree.
1347 - AM_PROG_CC_STDC is now empty. The content of this macro was
1348 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1349 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1350 renaming should be safe, even if you have to support several,
1351 versions of Automake, because AC_PROG_CC defines this variable
1352 since Autoconf 2.54.)
1354 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1355 variable to override the aclocal.m4 dependencies computed
1356 (inaccurately) by older versions of Automake. Because Automake
1357 now tracks configure's m4 dependencies accurately (see m4_include
1358 above), the use of ACLOCAL_M4_SOURCES should be considered
1359 obsolete and will be flagged as such when running `automake
1364 - Defining programs conditionally using Automake conditionals no
1365 longer leads to a combinatorial explosion. The following
1366 construct used to be troublesome when used with dozens of
1381 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1383 - Due to implementation constraints, previous versions of Automake
1384 proscribed multiple conditional definitions of some variables
1394 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1395 This restriction has been lifted, and these variables now
1396 support multiple conditional definitions as do other variables.
1398 - Cleanup the definitions of $(distdir) and $(top_distdir).
1399 $(top_distdir) now points to the root of the distribution
1400 directory created during `make dist', as it did in Automake 1.4,
1401 not to the root of the build tree as it did in intervening
1402 versions. Furthermore these two variables are now only defined in
1403 the top level Makefile, and passed to sub-directories when running
1406 - The --no-force option now correctly checks the Makefile.in's
1407 dependencies before deciding not to update it.
1409 - Do not assume that make files are called Makefile in cleaning rules.
1411 - Update .info files in the source tree, not in the build tree. This
1412 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1413 used to update these files in the build tree (previous versions did
1414 it in the source tree too), and it caused several problems, varying
1415 from mere annoyance to portability issues.
1417 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1418 when --add-missing and --force-missing are used. For backward
1419 compatibility --add-missing will continue to install COPYING (in
1420 `gnu' strictness) when none of these three files exist, but this
1421 use is deprecated: you should better choose a license yourself and
1422 install it once for all in your source tree (and in your code
1425 - Fix ylwrap so that it does not overwrite header files that haven't
1426 changed, as the inline rule already does.
1428 - User-defined rules override automake-defined rules for the same
1429 targets, even when rules do not have commands. This is not new
1430 (and was documented), however some of the automake-generated
1431 rules have escaped this principle in former Automake versions.
1432 Rules for the following targets are affected by this fix:
1434 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1435 info, info-am, install-data-am, install-exec-am, install-info,
1436 install-info-am, install-man, installcheck-am, maintainer-clean,
1437 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1438 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1440 Practically it means that an attempt to supplement the dependencies
1441 of some target, as in
1443 clean: my-clean-rule
1445 will now *silently override* the automake definition of the
1446 rule for this target. Running `automake -Woverride' will diagnose
1447 all such overriding definitions.
1449 It should be noted that almost all these targets support a *-local
1450 variant that is meant to supplement the automake-defined rule
1451 (See node `Extending' in the manual). The above rule should
1454 clean-local: my-clean-rule
1456 These *-local targets have been documented since at least
1457 Automake 1.2, so you should not fear the change if you have
1458 to support multiple automake versions.
1462 - The Automake manual is now distributed under the terms of the GNU FDL.
1464 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1466 - core dumps are no longer removed by the cleaning rules. There are
1467 at least three reasons for this:
1468 1. These files should not be created by any build step,
1469 so their removal do not fit any of the cleaning rules.
1470 Actually, they may be precious to the developer.
1471 2. If such file is created during a build, then it's clearly a
1472 bug Automake should not hide. Not removing the file will
1473 cause `make distcheck' to complain about its presence.
1474 3. Operating systems have different naming conventions for
1475 core dump files. A core file on one system might be a
1476 completely legitimate data file on another system.
1478 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1479 defined by Automake. This means that any definition in the
1480 environment will be used, unless overridden in the Makefile.am or
1481 on the command line. The old behavior, where these variables were
1482 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1483 AC_ARG_VARing each variable from configure.ac.
1485 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1486 documented. (The is not a new feature, these variables have
1487 been there since at least Automake 1.4.)
1489 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1492 * Fix install-strip to work with nobase_ binaries.
1493 * Fix renaming of #line directives in ylwrap.
1494 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1496 Bugs fixed in 1.7.8:
1497 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1498 * Fix detection of Debian's install-info, broken since version 1.5.
1499 (Debian bug #213524).
1500 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1501 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1503 Bugs fixed in 1.7.7:
1504 * The implementation of automake's --no-force option is unreliable,
1505 so this option is ignored in this version. A real fix will appear in
1506 Automake 1.8. (Debian Bug #206299)
1507 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1508 argument is given. (PR/399)
1509 * Do not warn about leading `_' in variable names, even with -Wportability.
1510 * Support user redefinitions of TEXINFO_TEX.
1511 * depcomp: support AIX Compiler version 6.
1512 * Fix missing rebuilds during `make dist' with BSD make.
1513 (Could produce tarballs containing out-of-date files.)
1514 * Resurrect multilib support.
1515 * Noteworthy manual updates:
1516 - Extending aclocal: how to write m4 macros that won't trigger warnings
1518 - A Shared Library: Rewrite and split into subsections.
1520 Bugs fixed in 1.7.6:
1521 * Fix depcomp's icc mode for ICC 7.1.
1522 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1523 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1524 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1525 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1526 * Remove Latin-1 characters from elisp-comp.
1527 * Update the manual's @dircategory to match the Free Software Directory.
1529 Bugs fixed in 1.7.5:
1530 * Update install-sh's license to remove an advertising clause.
1531 (Debian bug #191717)
1532 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1533 that caused invalid Makefile.ins to be generated.
1534 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1535 * New FAQ entry: renamed objects.
1537 Bugs fixed in 1.7.4:
1538 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1539 the Emacs implementation)
1540 * Fix output of aclocal.m4 dependencies in subdirectories.
1541 * Use `mv -f' instead of `mv' in fastdep rules.
1542 * Upgrade mdate-sh to work on OS/2.
1543 * Don't byte-compile elisp files when ELCFILES is set empty.

1550 * `make install' will build `BUILT_SOURCES' first.
1551 * Minor documentation fixes.
1553 Bugs fixed in 1.7.3:
1554 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1555 * Query distutils for `pythondir' and `pythonexecdir', instead of
1556 using an hardcoded path. This should allow builds on 64-bit
1557 distributions that usually use lib64/ instead of lib/.
1558 * AM_PATH_PYTHON will also search for python2.3.
1559 * elisp files are now built all at once instead of one by one. Besides
1560 incurring a speed-up, this is required to support interdependent elisp files.
1561 * Support for DJGPP:
1562 - `make distcheck' will now work in `_inst/' and `_build' instead
1563 of `=inst/' and `=build/'
1564 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1565 - install/uninstall `*.i[0-9][0-9]'-style info files
1566 - more changes that affect only the Automake package (not its output)
1567 * Fix some incompatibilities with upcoming perl-5.10.
1568 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1569 PACKAGE and VERSION.
1571 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1572 is troublesome with gcc and Solaris compilers. (PR/385)
1573 - makedepend mode: work with Libtool. (PR/385 too)
1575 * better support for unusual gettext setups, such as multiple po/ directories
1577 - Flag missing po/ and intl/ directories as warnings, not errors.
1578 - Disable these warnings if po/ does not exist.
1579 * Noteworthy manual updates:
1581 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1583 - Document `AM_YFLAGS = -d'. (PR/382)
1585 Bugs fixed in 1.7.2:
1586 * Fix installation and uninstallation of Info files built in subdirectories.
1587 * Do not run `./configure --with-included-gettext' during `make distcheck'
1588 if AM_GNU_GETTEXT([external]) is used.
1589 * Correctly uninstall renamed man pages.
1590 * Do not strip escaped newline in variables defined in one condition
1591 and augmented in another condition.
1592 * Fix ansi2knr rules for LIBOBJS sources.
1593 * Clean all known Texinfo index files, not only those which appear to
1594 be used, because we cannot know which indexes are used in included files.
1595 (PR/375, Debian Bug #168671)
1596 * Honor only the first @setfilename seen in a Texinfo file.
1597 * Treat "required file X not found" diagnostics as errors (exit status 1).
1598 * Don't complain that a required file is not found when it is a Makefile
1600 * Don't use single suffix inference rules when building `.info'-less
1601 Info files, for the sake of Solaris make.
1602 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1603 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1604 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1605 * Fix building of deansified files from subdirectories. (PR/370)
1606 * Add missing `fi' in the .c->.obj rules.
1607 * Improve install-sh to work even when names contain spaces or certain
1608 (but not all) shell metachars.
1609 * Fix the following spurious failures in the test suite:
1610 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1611 * Noteworthy manual updates:
1612 - Augment the section about BUILT_SOURCES.
1613 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1615 Bugs fixed in 1.7.1:
1616 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1618 * Aclocal should now recognize macro names containing parentheses, e.g.
1619 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1620 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1622 * Install Python files even if they were built. (PR/369)
1623 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1624 version might not be defined in the latter. (PR/358)
1625 * Reorder arguments passed to a couple of commands, so things works
1626 when POSIXLY_CORRECT=1.
1627 * Fix a regex that can cause Perl to segfault on large input.
1629 * Fix distribution of packages that have some sources defined conditionally,
1630 as in the `Conditional compilation using Automake conditionals' example
1632 * Fix spurious test suite failures on IRIX.
1633 * Don't report a required variable as undefined if it has been
1634 defined conditionally for the "right" conditions.
1635 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1636 `make distcheck' fails.
1637 * Fix distribution of included Makefile fragment, so we don't create
1638 spurious directories in the distribution. (PR/366)
1639 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1642 * Autoconf 2.54 is required.
1643 * `aclocal' and `automake' will no longer warn about obsolete
1644 configure macros. This is done by `autoconf -Wobsolete'.
1645 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1646 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1647 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1648 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1649 `configure.ac' for you.
1650 * Support for per-program and per-library `_CPPFLAGS'.
1651 * New `ctags' target (builds CTAGS files).
1652 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1653 (see `automake --help' or the manual for a list of them).
1654 * Honor the WARNINGS environment variable.
1655 * Omit the call to depcomp when using gcc3: call the compiler directly.
1656 * A new option, std-options, tests that programs support --help and --version
1657 when `make installcheck' is run. This is enabled by --gnits.
1658 * Texinfo rules now support the `ps' and `pdf' targets.
1659 * Info files are now created in the build directory, not the source directory.
1660 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1662 * `make distcheck' will enforce DESTDIR support by attempting
1664 * `+=' can be used in conditionals, even if the augmented variable
1665 was defined for another condition.
1666 * Makefile fragments (inserted with `include') are always distributed.
1667 * Use Autoconf's --trace interface to inspect configure.ac and get
1668 a more accurate view of it.
1669 * Add support for extending aclocal's default macro search path
1670 using a `dirlist' file within the aclocal directory.
1671 * automake --output-dir is deprecated.
1672 * The part of the distcheck target that checks whether uninstall actually
1673 removes all installed files has been moved in a separate target,
1674 distuninstallcheck, so it can be overridden easily.
1678 * Support for AM_INIT_GETTEXT([external])
1679 * Bug fixes, including:
1680 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1681 - nobase_ programs and scripts honor --program-transform correctly.
1682 - Erase configure.lineno during `make distclean'.
1683 - Erase YACC and LEX outputs during `make maintainer-clean'.
1686 * Many bug fixes, including:
1687 - Requiring the current version works.
1688 - Fix "$@" portability issues (for Zsh).
1689 - Fix output of dummy dependency files in presence of post-processed
1691 - Don't compute dependencies in background to avoid races with libtool.
1692 - Fix handling of _OBJECTS variables for targets sharing source variables.
1693 - Check dependency mode for Java when AM_PROG_GCJ is used.
1696 * automake --output-dir is deprecated
1697 * Many bug fixes, including:
1698 - Don't choke on AM_LDFLAGS definitions.
1699 - Clean libtool objects from subdirectories.
1700 - Allow configure variables with reserved suffix and unknown prefix
1701 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1702 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1705 * Autoconf 2.52 is required.
1706 * automake no longer run libtoolize.
1707 This is the job of autoreconf (from GNU Autoconf).
1708 * `dist' generates all the archive flavors, as did `dist-all'.
1709 * `dist-gzip' generates the Gzip tar file only.
1710 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1711 explosion. Makefile.in's keep a reasonable size.
1712 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1713 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1715 * `#line' of Lex and Yacc files are properly set.
1716 * EXTRA_DIST can contain generated directories.
1717 * Support for dot-less extensions in suffix rules.
1718 * The part of the distcheck target that checks whether distclean actually
1719 cleans all built files has been moved in a separate target, distcleancheck,
1720 so it can be overridden easily.
1721 * `make distcheck' will pass additional options defined in
1722 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1723 * Fixed CDPATH portability problems, in particular for MacOS X.
1724 * Fixed handling of nobase_ targets.
1725 * Fixed support of implicit rules leading to .lo objects.
1726 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1727 * Added uninstall-hook target
1728 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1729 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1730 (Note that "pkgname" is not "tarname", see the manual for details.)
1731 It is also possible to pass a list of global Automake options as
1732 first argument to this new form of AM_INIT_AUTOMAKE.
1733 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1734 to be a real assembler.
1735 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1736 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1737 * aclocal and automake are also installed with the version number
1738 appended, and some of the install directory names have changed.
1739 This lets you have multiple versions installed simultaneously.
1740 * Support for parsers and lexers in subdirectories.
1743 * Support for `configure.ac'.
1744 * Support for `else COND', `endif COND' and negated conditions `!COND'.
1745 * `make dist-all' is much faster.
1746 * Allows '@' AC_SUBSTs in macro names.
1747 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
1748 * User-side dependency tracking. Developers no longer need GNU make
1750 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
1751 * Most files are correctly handled if they appear in subdirs
1752 For instance, a _DATA file can appear in a subdir
1753 * GNU tar is no longer required for `make dist'
1754 * Added support for `dist_' and `nodist_' prefixes
1755 * Added support for `nobase_' prefix
1756 * Compiled Java support
1757 * Support for per-executable and per-library compilation flags
1761 * Added support for the Fortran 77 programming language.
1762 * Re-indexed the Automake Texinfo manual.
1763 * Added `AM_FOOFLAGS' variable for each compiler invocation;
1764 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
1765 * Support for latest autoconf, including support for objext
1766 * Can now put `.' in SUBDIRS to control build order
1767 * `include' command and `+=' support for macro assignment
1768 * Dependency tracking no long susceptible to deleted header file problem
1769 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
1774 * Better Cygwin32 support
1775 * Support for suffix rules with _SOURCES variables
1776 * New options `readme-alpha' and `check-news'; Gnits mode sets these
1777 * @LEXLIB@ no longer required when lex source seen
1778 Lex support in `missing', and new lex macro. Update your missing script.
1779 * Built-in support for assembly
1780 * aclocal gives error if `AM_' macro not found
1781 * Passed YFLAGS, not YACCFLAGS, to yacc
1782 * AM_PROG_CC_STDC does not have to come before AC_PROG_CPP
1783 * Dependencies computed as a side effect of compilation
