3 * WARNING: Future backward-incompatibilities!
5 - Starting from the next major Automake version (1.13), the parallel
6 testsuite harness (previously only enabled by the 'parallel-tests'
7 option) will become the default one; the older serial testsuite
8 harness will still be available through the use of the 'serial-tests'
11 - The following long-obsolete m4 macros will be removed in the
12 next major Automake version (1.13):
14 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
15 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
16 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
17 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
18 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
19 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
20 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
21 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
22 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
23 of the now-removed automatic de-ANSI-fication
26 - All the "old alias" macros in 'm4/obsolete.m4' will be removed in
27 the next major Automake version (1.13).
29 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option)
30 will be deprecated in the next minor version of Automake (1.12.1) and
31 removed in the next major version (1.13).
33 - Support for the two- and three-arguments invocation forms of the
34 AM_INIT_AUTOMAKE macro will be deprecated in the next minor version
35 of Automake (1.12.1) and removed in the next major version (1.13).
37 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
38 variable, @mkdir_p@ substitution and AM_PROG_MKDIR m4 macro will
39 all be deprecated in the next minor version of Automake (1.12.1)
40 and removed in the next major version (1.13).
42 - The '--acdir' option of aclocal is deprecated, and will probably
43 be removed in the next major Automake release (1.13). You should
44 use the options '--automake-acdir' and '--system-acdir' instead
45 (which have been introduced in Automake 1.11.2).
47 - The exact order in which the directories in the aclocal macro
48 search path are looked up is probably going to be changed in the
49 next Automake release (1.13).
51 * Obsolete features removed:
53 - The never documented nor truly used script 'acinstall' has been
56 - Support for automatic de-ANSI-fication has been removed.
58 - The support for the "obscure" multilib feature has been removed
59 from Automake core (but remains available in the 'contrib/'
60 directory of the Automake distribution).
62 - Support for ".log -> .html" conversion and the check-html and
63 recheck-html targets has been removed from Automake core (but
64 remains available in the 'contrib/' directory of the Automake
67 - The deprecated 'lzma' compression format for distribution archives
68 has been removed, in favor of 'xz' and 'lzip'.
70 - The obsolete AM_WITH_REGEX macro has been removed.
72 - The long-deprecated options '--output-dir', '--Werror' and
73 '--Wno-error' have been removed.
75 - The chapter on the history of Automake has been moved out of the
76 reference manual, into a new dedicated Texinfo file.
80 - New 'cscope' target to build a cscope database for the source tree.
82 * Changes to Automake-generated testsuite harnesses:
84 - The new automake option 'serial-tests' has been introduced. It can
85 be used to explicitly instruct automake to use the older serial
86 testsuite harness. This is still the default at the moment, but it
87 might change in future versions.
89 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
90 and unexpected or internal error, or a failure to set up the test case
91 scenario) have their outcome reported as an 'ERROR' now. Previous
92 versions of automake reported such an outcome as a 'FAIL' (the only
93 difference with normal failures being that hard errors were counted
94 as failures even when the test originating them was listed in
97 - The testsuite summary displayed by the parallel-test harness has a
98 completely new format, that always list the numbers of passed, failed,
99 xfailed, xpassed, skipped and errored tests, even when these numbers
100 are zero (but using smart coloring when the color-tests option is in
103 - The default testsuite driver offered by the 'parallel-tests' option is
104 now implemented (partly at least) with the help of automake-provided
105 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
106 on code in the generated Makefile.in.
107 This has two noteworthy implications. The first one is that projects
108 using the 'parallel-tests' option should now either run automake with
109 the '--add-missing' option, or manually copy the 'test-driver' script
110 into their tree. The second, and more important, implication is that
111 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
112 not be used anymore to define a test runner, and the command specified
113 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
114 program or script. For example, this is still a valid usage (albeit
117 TESTS_ENVIRONMENT = \
118 if test -n '$(STRICT_TESTS)'; then \
119 maybe_errexit='-e'; \
123 LOG_COMPILER = $(SHELL) $$maybe_errexit
125 while this is not anymore:
127 TESTS_ENVIRONMENT = \
128 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
132 TESTS_ENVIRONMENT = \
133 run_with_perl_or_shell () \
135 if grep -q '^#!.*perl' $$1; then
141 LOG_COMPILER = run_with_per_or_shell
143 - The package authors can now use customary testsuite drivers within
144 the framework provided by the 'parallel-tests' testsuite harness.
145 Consistently with the existing syntax, this can be done by defining
146 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
148 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
149 to redirect/define file descriptors used by the test scripts.
151 - The parallel-tests harness generates now, in addition the '.log' files
152 holding the output produced by the test scripts, a new set of '.trs'
153 files, holding "metadata" derived by the execution of the test scripts;
154 among such metadata are the outcomes of the test cases run by a script.
156 - Initial and still experimental support for the TAP test protocol is
159 * Changes to Yacc and Lex support:
161 - C source and header files derived from non-distributed Yacc and/or
162 Lex sources are now removed by a simple "make clean" (while they were
163 previously removed only by "make maintainer-clean").
165 - Slightly backward-incompatible change, relevant only for use of Yacc
166 with C++: the extensions of the header files produced by the Yacc
167 rules are now modelled after the extension of the corresponding
168 sources. For example, yacc files named "foo.y++" and "bar.yy" will
169 produce header files named "foo.h++" and "bar.hh" respectively, where
170 they would have previously produced header files named simply "foo.h"
171 and "bar.h". This change offers better compatibility with 'bison -o'.
173 * Miscellaneous changes:
175 - Automake now prefers to quote 'like this' or "like this", rather
176 than `like this', in diagnostic message and generated Makefiles,
177 to accommodate the new GNU Coding Standards recommendations.
179 - Automake has a new option '--print-libdir' that prints the path of the
180 directory containing the Automake-provided scripts and data files.
182 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
184 - Automake can now generate silenced rules for texinfo outputs.
186 - Some auxiliary files that are automatically distributed by Automake
187 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
188 C sources) might now be listed in the DIST_COMMON variable in many
189 Makefile.in files, rather than in the top-level one.
191 - Messages of types warning or error from 'automake' and 'aclocal'
192 are now prefixed with the respective type, and presence of -Werror
195 - Automake's early configure-time sanity check now tries to avoid
196 sleeping for a second, which slowed down cached configure runs
197 noticeably. In that case, it will check back at the end of the
198 configure script to ensure that at least one second has passed, to
199 avoid time stamp issues with makefile rules rerunning autotools
202 - The warnings in the category 'extra-portability' are now enabled by
203 '-Wall'. In previous versions, one has to use '-Wextra-portability'
208 - Various minor bugfixes for recent or long-standing bugs.
210 * Bugs introduced by 1.11:
212 - The AM_COND_IF macro also works if the shell expression for the
213 conditional is no longer valid for the condition.
215 - The automake-provided parallel testsuite harness does not fail anymore
216 with BSD make used in parallel mode when there are test scripts in a
217 subdirectory, like in:
219 TESTS = sub/foo.test sub/bar.test
221 * Long-standing bugs:
223 - Automake's own build system finally have a real "installcheck" target.
225 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
226 now automatically distributed also if the directory of the auxiliary
227 files coincides with the top-level directory.
229 - Automake now detects the presence of the '-d' flag in the various
230 '*YFLAGS' variables even when their definitions involve indirections
231 through other variables, such as in:
233 AM_YFLAGS = $(foo_opts)
235 - Automake now complains if a '*YFLAGS' variable has any conditional
236 content, not only a conditional definition.
238 - Explicit enabling and/or disabling of Automake warning categories
239 through the '-W...' options now always takes precedence over the
240 implicit warning level implied by Automake strictness (foreign, gnu
241 or gnits), regardless of the order in which such strictness and
242 warning flags appear. For example, a setting like:
243 AUTOMAKE_OPTIONS = -Wall --foreign
244 will cause the warnings in category 'portability' to be enabled, even
245 if those warnings are by default disabled in 'foreign' strictness.
247 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
251 * WARNING: Future backward-incompatibilities!
253 - The support for the "obscure" multilib feature has been deprecated,
254 and will be moved out of the automake core in the next major Automake
257 - The support for ".log -> .html" conversion and the check-html and
258 recheck-html targets will be removed in the next major Automake
261 - The obsolescent AM_WITH_REGEX macro has been deprecated (since the
262 GNU rx library has been decommissioned), and will be removed in the
263 next major Automake release (1.12).
265 - The `lzma' compression format for distribution archives has been
266 deprecated in favor of `xz' and `lzip', and will be removed in the
267 next major Automake release (1.12).
269 - The `--acdir' option of aclocal is deprecated, and will probably be
270 removed in the next major Automake release (1.12).
272 - The exact order in which the directories in the aclocal macro
273 search path are looked up is probably going to be changed in the
274 next Automake release (1.12).
276 - The Automake support for automatic de-ANSI-fication will be removed
277 in the next major Automake release (1.12).
279 - Starting from the next Automake release (1.12), warnings in the
280 `extra-portability' category will be enabled by `-Wall' (right now,
281 one has to use `-Wextra-portability' explicitly).
283 * Miscellaneous changes:
285 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
286 symbol index) modifiers as well as the "s" action, as the symbol index
287 is created unconditionally by Microsoft lib. Also, the "q" (quick)
288 action is now a synonym for "r" (replace). Also, the script has been
289 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
291 - When the 'compile' script is used to wrap MSVC, it now accepts an
292 optional space between the -I, -L and -l options and their respective
293 arguments, for better POSIX compliance.
295 - There is an initial, experimental support for automatic dependency
296 tracking with tcc (the Tiny C Compiler). Its associated depmode is
297 currently recognized as "icc" (but this and other details are likely
298 to change in future versions).
300 - Automatic dependency tracking now works also with the IBM XL C/C++
301 compilers, thanks to the new new depmode 'xlc'.
303 Bugs fixed in 1.11.4:
305 * Bugs introduced by 1.11.2:
307 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
308 don't cause spurious failures upon "make install" anymore.
310 - The user can now instruct the 'uninstall-info' rule not to update
311 the '${infodir}/dir' file by exporting the environment variable
312 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
313 with how the 'install-info' rule operates since automake 1.11.2.
315 * Long-standing bugs:
317 - It is now possible for a foo_SOURCES variable to hold Vala sources
318 together with C header files, as well as with sources and headers for
319 other supported languages (e.g., C++). Previously, only mixing C and
320 Vala sources was supported.
322 - If "aclocal --install" is used, and the first directory specified with
323 '-I' is non-existent, aclocal will now create it before trying to copy
326 - An empty declaration of a "foo_PRIMARY" don't cause anymore the
327 generated install rules to create an empty $(foodir) directory;
328 for example, if Makefile.am contains something like:
332 pkglibexec_SCRIPTS += bar.sh
335 the $(pkglibexec) directory will not be created upon "make install".
337 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
341 * Miscellaneous changes:
343 - Automake's own build system is more silent by default, making use of
344 the 'silent-rules' option.
346 - The master copy of the `gnupload' script is now maintained in gnulib,
349 - The `missing' script doesn't try to wrap calls to `tar' anymore.
351 - "make dist" doesn't wrap `tar' invocations with the `missing' script
352 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
353 shouldn't be using BTW ;-) does not invoke the missing script anymore
354 to wrap tar, but simply invokes the `tar' program itself.
356 - "make dist" can now create lzip-compressed tarballs.
358 - In the Automake info documentation, the Top node and the nodes about
359 the invocation of the automake and aclocal programs have been renamed;
360 now, calling "info automake" will open the Top node, while calling
361 "info automake-invocation" and "info aclocal-invocation" will access
362 the nodes about the invocation of respectively automake and aclocal.
364 - Automake is now distributed as a gzip-compressed and an xz-compressed
365 tarball. Previously, bzip2 was used instead of xz.
367 - The last relics of Python 1.5 support have been removed from the
368 AM_PATH_PYTHON macro.
370 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
371 and adds them to the normal list of dependencies, but without
372 overwriting the foo_DEPENDENCIES variable, which is normally computed
375 Bugs fixed in 1.11.3:
377 * Bugs introduced by 1.11.2:
379 - Automake now correctly recognizes the prefix/primary combination
380 `pkglibexec_SCRIPTS' as valid.
382 - The parallel-tests harness doesn't trip anymore on sed implementations
383 with stricter limits on the length of input lines (problem seen at
386 * Long-standing bugs:
388 - The "deleted header file problem" for *.am files is avoided by stub
389 rules. This allows `make' to trigger a rerun of `automake' also if
390 some previously needed `.am' file has been removed.
392 - The `silent-rules' option now generates working makefiles even
393 for the uncommon `make' implementations that do not support the
394 nested-variables extension to POSIX 2008. For such `make'
395 implementations, whether a build is silent is determined at
396 configure time, and cannot be overridden at make time with
397 `make V=0' or `make V=1'.
399 - Vala support now works better in VPATH setups.
401 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
405 * Changes to aclocal:
407 - The `--acdir' option is deprecated. Now you should use the new options
408 `--automake-acdir' and `--system-acdir' instead.
410 - The `ACLOCAL_PATH' environment variable is now interpreted as a
411 colon-separated list of additional directories to search after the
412 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
413 and before the system acdir (by default ${prefix}/share/aclocal).
415 * Miscellaneous changes:
417 - The Automake support for automatic de-ANSI-fication has been
418 deprecated. It will probably be removed in the next major Automake
421 - The `lzma' compression scheme and associated automake option `dist-lzma'
422 is obsoleted by `xz' and `dist-xz' due to upstream changes.
424 - You may adjust the compression options used in dist-xz and dist-bzip2.
425 The default is now merely -e for xz, but still -9 for bzip; you may
426 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
427 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
429 - The `compile' script now converts some options for MSVC for a better
430 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
432 - The py-compile script now accepts empty arguments passed to the options
433 `--destdir' and `--basedir', and complains about unrecognized options.
434 Moreover, a non-option argument or a special `--' argument terminates
437 - A developer that needs to pass specific flags to configure at "make
438 distcheck" time can now, and indeed is advised to, do so by defining
439 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
440 instead of the old DISTCHECK_CONFIGURE_FLAGS.
441 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
442 user; still, the old Makefile.am files that used to define it will
443 still continue to work as before.
445 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
446 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
447 This new macro is required for LIBRARIES and LTLIBRARIES when automake
448 is run with -Wextra-portability and -Werror.
450 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
451 file generated by automake-provided rules by defining the special make
452 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
454 - The `install-info' rule can now be instructed not to create/update
455 the `${infodir}/dir' file, by exporting the new environment variable
456 `AM_UPDATE_INFO_DIR' to the value "no".
458 Bugs fixed in 1.11.2:
460 * Bugs introduced by 1.11:
462 - The parallel-tests driver no longer produces erroneous results with
463 Tru64/OSF 5.1 sh upon unreadable log files.
465 - The `parallel-tests' test driver does not report spurious successes
466 when used with concurrent FreeBSD make (e.g., "make check -j3").
468 - When the parallel-tests driver is in use, automake now explicitly
469 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
470 instead of issuing confusing and apparently unrelated error messages
471 (e.g., "non-POSIX variable name", "bad characters in variable name",
472 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
473 silently producing broken `Makefile.in' files.
475 - The `silent-rules' option now truly silences all compile rules, even
476 when dependency tracking is disabled. Also, when `silent-rules' is
477 not used, `make' output no longer contains spurious backslash-only
478 lines, thus once again matching what Automake did before 1.11.
480 - The AM_COND_IF macro also works if the shell expression for the
481 conditional is no longer valid for the condition.
483 * Long-standing bugs:
485 - The order of Yacc and Lex flags is fixed to be consistent with other
486 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
487 $(LFLAGS), so that the user variables override the developer variables.
489 - "make distcheck" now correctly complains also when "make uninstall"
490 leaves one and only one file installed in $(prefix).
492 - A "make uninstall" issued before a "make install", or after a mere
493 "make install-data" or a mere "make install-exec" does not spuriously
496 - Automake now warns about more primary/directory invalid combinations,
497 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
499 - Rules generated by Automake now try harder to not change any files when
500 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
501 Yacc source files and the rule to update config.h.
503 - Several scripts and the parallel-tests testsuite driver now exit with
504 the right exit status upon receiving a signal.
506 - A per-Makefile.am setting of -Werror does not erroneously carry over
507 to the handling of other Makefile.am files.
509 - The code for automatic dependency tracking works around a Solaris
510 make bug triggered by sources containing repeated slashes when the
511 `subdir-objects' option was used.
513 - The makedepend and hp depmodes now work better with VPATH builds.
515 - Java sources specified with check_JAVA are no longer compiled for
516 "make all", but only for "make check".
518 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
519 and error out if `javadir' is undefined, instead of silently producing
520 a broken Makefile.in.
522 - aclocal and automake now honour the configure-time definitions of
523 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
525 - The `install-info' recipe no longer tries to guess whether the
526 `install-info' program is from Debian or from GNU, and adaptively
527 change its behaviour; this has proven to be frail and easy to
530 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
532 Bugs fixed in 1.11.1:
534 - Lots of minor bugfixes.
536 * Bugs introduced by 1.11:
538 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
539 trailing white space in the test list (`TESTS = foo $(EMPTY)').
541 * Long standing bugs:
543 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
544 even if the `--prefix' argument pointed outside of a system directory.
545 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
546 `get_python_lib' function if it points outside the configured prefix,
547 unless the `--prefix' argument was either `/usr' or below `/System'.
549 - The testsuite does not try to change the mode of `ltmain.sh' files from
550 a Libtool installation (symlinked to test directories) any more.
552 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
553 tools are preferred in a cross-compile setup.
555 - The distribution is tarred up with mode 755 now by the `dist*' targets.
556 This fixes a race condition where untrusted users could modify files
557 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
558 build directory was world-searchable. This is CVE-2009-4029.
560 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
564 * Version requirements:
566 - Autoconf 2.62 or greater is required.
568 * Changes to aclocal:
570 - The autoconf version check implemented by aclocal in aclocal.m4
571 (and new in Automake 1.10) is degraded to a warning. This helps
572 in the common case where the Autoconf versions used are compatible.
574 * Changes to automake:
576 - The automake program can run multiple threads for creating most
577 Makefile.in files concurrently, if at least Perl 5.7.2 is available
578 with interpreter-based threads enabled. Set the environment variable
579 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
580 enable this experimental feature.
582 * Changes to Libtool support:
584 - Libtool generic flags are now passed to the install and uninstall
587 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
588 config.lt is removed correctly now.
592 - subdir-object mode works now with Fortran (F77, FC, preprocessed
593 Fortran, and Ratfor).
595 - For files with extension .f90, .f95, .f03, or .f08, the flag
596 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
598 - Files with extension .sx are also treated as preprocessed assembler.
600 - The default source file extension (.c) can be overridden with
601 AM_DEFAULT_SOURCE_EXT now.
603 - Python 3.0 is supported now, Python releases prior to 2.0 are no
606 - AM_PATH_PYTHON honors python's idea about the site directory.
608 - There is initial support for the Vala programming language, when using
611 * Miscellaneous changes:
613 - Automake development is done in a git repository on Savannah now, see
615 http://git.sv.gnu.org/gitweb/?p=automake.git
617 A read-only CVS mirror is provided at
619 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
620 checkout -d automake HEAD
622 - "make dist" can now create xz-compressed tarballs,
623 as well as (deprecated?) lzma-compressed tarballs.
625 - `automake --add-missing' will by default install the GPLv3 file as
626 COPYING if it is missing. It will also warn that the license file
627 should be added to source control. Note that Automake will never
628 overwrite an existing COPYING file, even when the `--force-missing'
631 - The manual is now distributed under the terms of the GNU FDL 1.3.
633 - Automake ships and installs man pages for automake and aclocal now.
635 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
637 - install-sh supports -C, which does not update the installed file
638 (and its time stamps) if the contents did not change.
640 - The `gnupload' script has been revamped.
642 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
644 - The targets `install' and `uninstall' are more efficient now, in that
645 for example multiple files from one Automake variable such as
646 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
647 invocation if they do not have to be renamed.
649 Both install and uninstall may sometimes enter (`cd' into) the target
650 installation directory now, when no build-local scripts are used.
652 Both install and uninstall do not fail anymore but do nothing if an
653 installation directory variable like `bindir' is set to the empty string.
655 For built-in rules, `make install' now fails reliably if installation
656 of a file failed. Conversely, `make uninstall' even succeeds when
657 issued multiple times.
659 These changes may need some adjustments from users: For example,
660 some `install' programs refuse to install multiple copies of the
661 same file in one invocation, so you may need to remove duplicate
662 entries from file lists.
664 Also, within one set of files, say, nobase_data_DATA, the order of
665 installation may be changed, or even unstable among different hosts,
666 due to the use of associative arrays in awk. The increased use of
667 awk matches a similar move in Autoconf to provide for better scaling.
669 Further, most undocumented per-rule install command variables such as
670 binSCRIPT_INSTALL have been removed because they are not needed any
671 more. Packages which use them should be using the appropriate one of
672 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
673 counterpart, depending on the type of files and the need for automatic
674 target directory creation.
676 - The "deleted header file problem" for *.m4 files is avoided by
677 stub rules. This allows `make' to trigger a rerun of `aclocal'
678 also if some previously needed macro file has been removed.
680 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
681 an otherwise up to date tree.
683 - The `color-tests' option causes colored test result output on terminals.
685 - The `parallel-tests' option enables a new test driver that allows for
686 parallel test execution, inter-test dependencies, lazy test execution
687 for unit-testing, re-testing only failed tests, and formatted result output
688 as RST (reStructuredText) and HTML. Enabling this option may require some
689 changes to your test suite setup; see the manual for details.
691 - The `silent-rules' option enables Linux kernel-style silent build output.
692 This option requires the widely supported but non-POSIX `make' feature
693 of recursive variable expansion, so do not use it if your package needs
694 to build with `make' implementations that do not support it.
696 To enable less verbose build output, the developer has to use the Automake
697 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
698 macro. The user may then set the default verbosity by passing the
699 `--enable-silent-rules' option to `configure'. At `make' run time, this
700 default may be overridden using `make V=0' for less verbose, and `make V=1'
701 for backward-compatible verbose output.
703 - New prefix `notrans_' for manpages which should not be transformed
704 by --program-transform.
706 - New macro AM_COND_IF for conditional evaluation and conditional
709 - For AC_CONFIG_LINKS, if source and destination are equal, do not
710 remove the file in a non-VPATH build. Such setups work with Autoconf
713 - AM_MAINTAINER_MODE now allows for an optional argument specifying
716 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
717 useful especially for multi-line values.
719 - Automake's early configure-time sanity check now diagnoses an
720 unsafe absolute source directory name and makes configure fail.
722 - The Automake macros and rules cope better with whitespace in the
723 current directory name, as long as the relative path to `configure'
724 does not contain whitespace. To this end, the values of `$(MISSING)'
725 and `$(install_sh)' may contain suitable quoting, and their expansion
726 might need `eval'uation if used outside of a makefile. These
727 undocumented variables may be used in several documented macros such
728 as $(AUTOCONF) or $(MAKEINFO).
732 * Long-standing bugs:
734 - Fix aix dependency tracking for libtool objects.
736 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
737 unnecessary use of the `compile' script.
739 - For nobase_*_LTLIBRARIES with nonempty directory components, the
740 correct `-rpath' argument is used now.
742 - `config.status --file=Makefile depfiles' now also works with the
743 extra quoting used internally by Autoconf 2.62 and newer
744 (it used to work only without the `--file=' bit).
746 - The `missing' script works better with versioned tool names.
748 - Semantics for `missing help2man' have been revamped:
750 Previously, if `help2man' was not present, `missing help2man' would have
751 the following semantics: if some man page was out of date but present, then
752 a warning would be printed, but the exit status was 0. If the man page was
753 not present at all, then `missing' would create a replacement man page
754 containing an error message, and exit with a status of 2. This does not play
755 well with `make': the next run will see this particular man page as being up
756 to date, and will only error out on the next generated man page, if any;
757 repeat until all pages are done. This was not desirable.
759 These are the new semantics: if some man page is not present, and help2man
760 is not either, then `missing' will warn and generate the replacement page
761 containing the error message, but exit successfully. However, `make dist'
762 will ensure that no such bogus man pages are packaged into a tarball.
764 - Targets provided by automake behave better with `make -n', in that they
765 take care not to create files.
767 - `config.status Makefile... depfiles' works fine again in the presence of
768 disabled dependency tracking.
770 - The default no-op recursive rules for these targets also work with BSD make
771 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
773 - `make distcheck' works also when both a directory and some file below it
774 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
776 - Texinfo dvi, ps, pdf, and html output files are not removed upon
777 `make mostlyclean' any more; only the LaTeX by-products are.
779 - Renamed objects also work with the `subdir-objects' option and
780 source file languages which Automake does not know itself.
782 - `automake' now correctly complains about variable assignments which are
783 preceded by a comment, extend over multiple lines with backslash-escaped
784 newlines, and end in a comment sign. Previous versions would silently
785 and wrongly ignore such assignments completely.
787 * Bugs introduced by 1.10:
789 - Fix output of dummy dependency files in presence of post-processed
790 Makefile.in's again, but also cope with long lines.
792 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
793 that have been declared as programs in the same Makefile.
794 This is for consistency with the analogous change to TESTS in 1.10.
796 - Fix order of standard includes to again be `-I. -I$(srcdir)',
797 followed by directories containing config headers.
799 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
803 * Version requirements:
805 - Autoconf 2.60 or greater is required.
807 - Perl 5.6 or greater is required.
809 * Changes to aclocal:
811 - aclocal now also supports -Wmumble and -Wno-mumble options.
813 - `dirlist' entries (for the aclocal search path) may use shell
814 wildcards such as `*', `?', or `[...]'.
816 - aclocal supports an --install option that will cause system-wide
817 third-party macros to be installed in the local directory
818 specified with the first -I flag. This option also uses #serial
819 lines in M4 files to upgrade local macros.
821 The new aclocal options --dry-run and --diff help to review changes
822 before they are installed.
824 - aclocal now outputs an autoconf version check in aclocal.m4 in
825 projects using automake.
827 For a few years, automake and aclocal have been calling autoconf
828 (or its underlying engine autom4te) to accurately retrieve the
829 data they need from configure.ac and its siblings. Doing so can
830 only work if all autotools use the same version of autoconf. For
831 instance a Makefile.in generated by automake for one version of
832 autoconf may stop working if configure is regenerated with another
833 version of autoconf, and vice versa.
835 This new version check ensures that the whole build system has
836 been generated using the same autoconf version.
838 * Support for new Autoconf macros:
840 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
842 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
843 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
844 in different directories. However, only one instance of such a
845 library objects directory is supported.
847 * Change to Libtool support:
849 - Libtool generic flags (those that go before the --mode=MODE option)
850 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
852 * Yacc and Lex changes:
854 - The rebuild rules for distributed Yacc and Lex output will avoid
855 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
858 - ylwrap is now always used for lex and yacc source files,
859 regardless of whether there is more than one source per directory.
863 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
864 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
865 tracking, unlike non-preprocessed assembler (*.s).
867 - subdir-object mode works now with Assembler. Automake assumes
868 that the compiler understands `-c -o'.
870 - Preprocessed assembler (*.S) compilation now also honors
871 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
873 - Improved support for Objective C:
874 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
875 - A new section of the manual documents the support.
877 - New support for Unified Parallel C:
878 - AM_PROG_UPC looks for a UPC compiler.
879 - A new section of the manual documents the support.
881 - Per-target flags are now correctly handled in link rules.
883 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
884 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
885 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
886 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
888 The fix for compiler flags (i.e., using maude_CFLAGS instead of
889 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
890 is expected to work (and actually works during compilation).
892 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
893 "in addition to" breaks backward compatibility with older versions.
894 If your package used both variables, as in
896 AM_LDFLAGS = common flags
898 a_LDFLAGS = more flags
901 and assumed *_LDFLAGS would sum up, you should rewrite it as
903 AM_LDFLAGS = common flags
905 a_LDFLAGS = $(AM_LDFLAGS) more flags
908 This new behavior of *_LDFLAGS is more coherent with other
909 per-target variables, and the way *_LDFLAGS variables were
910 considered internally.
912 * New installation targets:
914 - New targets mandated by GNU Coding Standards:
919 By default they will only install Texinfo manuals.
920 You can customize them with *-local variants:
926 - The undocumented recursive target `uninstall-info' no longer exists.
927 (`uninstall' is in charge of removing all possible documentation
928 flavors, including optional formats such as dvi, ps, or info even
929 when `no-installinfo' is used.)
931 * Miscellaneous changes:
933 - Automake no longer complains if input files for AC_CONFIG_FILES
934 are specified using shell variables.
936 - clean, distribution, or rebuild rules are normally disabled for
937 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
938 AC_CONFIG_LINK specified using shell variables. However, if these
939 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
940 be able to output rules anyway.
941 (See the Automake documentation for AC_CONFIG_FILES.)
943 - $(EXEEXT) is automatically appended to filenames of TESTS
944 that have been declared as programs in the same Makefile.
945 This is mostly useful when some check_PROGRAMS are listed in TESTS.
947 - `-Wportability' has finally been turned on by default for `gnu' and
948 `gnits' strictness. This means, automake will complain about %-rules
949 or $(GNU Make functions) unless you switch to `foreign' strictness or
950 use `-Wno-portability'.
952 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
953 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
954 $(mkdir_p) variable is still defined (to the same value as
955 $(MKDIR_P)) but should be considered obsolete. If you are using
956 $(mkdir_p) in some of your rules, please plan to update them to
957 $(MKDIR_P) at some point.
959 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
960 They still work in this release, but may be withdrawn in a future one.
962 - Inline compilation rules for gcc3-style dependency tracking are
965 - Automake installs a "Hello World!" example package in $(docdir).
966 This example is used throughout the new "Autotools Introduction"
967 chapter of the manual.
969 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
973 * Makefile.in bloat reduction:
975 - Inference rules are used to compile sources in subdirectories when
976 the `subdir-objects' option is used and no per-target flags are
977 used. This should reduce the size of some projects a lot, because
978 Automake used to output an explicit rule for each such object in
981 - Automake no longer outputs three rules (.o, .obj, .lo) for each
982 object that must be built with explicit rules. It just outputs
983 the rules required to build the kind of object considered: either
984 the two .o and .obj rules for usual objects, or the .lo rule for
987 * Change to Libtool support:
989 - Libtool tags are used with libtool versions that support them.
990 (I.e., with Libtool 1.5 or greater.)
992 - Automake is now able to handle setups where a libtool library is
993 conditionally installed in different directories, as in
996 lib_LTLIBRARIES = liba.la
998 pkglib_LTLIBRARIES = liba.la
1000 liba_la_SOURCES = ...
1002 * Changes to aclocal:
1004 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1005 really evaluated, before it decides to include them in aclocal.m4.
1006 This solves nasty problems with conditional redefinitions of
1007 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1008 *.m4 files to be included in any project using these macros.
1009 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1010 most famous instance of this bug.)
1012 - Do not complain about missing conditionally AC_REQUIREd macros
1013 that are not actually used. In 1.8.x aclocal would correctly
1014 determine which of these macros were really needed (and include
1015 only these in the package); unfortunately it would also require
1016 all of them to be present in order to run. This created
1017 situations were aclocal would not work on a tarball distributing
1018 all the macros it uses. For instance running aclocal on a project
1019 containing only the subset of the Gettext macros in use by the
1020 project did not work, because gettext conditionally requires other
1023 * Portability improvements:
1025 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1026 tar-pax. The new option filename-length-max=99 helps diagnosing
1027 filenames that are too long for tar-v7. (PR/414)
1029 - Variables aumented with `+=' are now automatically flattened (i.e.,
1030 trailing backslashes removed) and then wrapped around 80 colummns
1031 (adding trailing backslashes). In previous versions, a long series
1037 would result in a single-line definition of VAR that could possibly
1038 exceed the maximum line length of some make implementations.
1040 Non-augmented variables are still output as they are defined in
1045 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1046 Works the same as the old Fortran 77 implementation; just replace
1047 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1048 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1050 - Support for conditional _LISP.
1052 - Support for conditional -hook and -local rules (PR/428).
1054 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1056 - Automake will not write any Makefile.ins after the first error it
1057 encounters. The previous Makefile.ins (if any) will be left in
1058 place. (Warnings will not prevent output, but remember they can
1059 be turned into errors with -Werror.)
1061 - The restriction that SUBDIRS must contain direct children is gone.
1064 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1065 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1067 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1069 Bugs fixed in 1.8.5:
1071 * Long-standing bugs:
1073 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1074 so that `make distclean' and `make maintainer-clean' can work.
1076 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1078 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1080 - Polish diagnostic when no input file is found.
1082 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1084 Bugs fixed in 1.8.4:
1086 * Long-standing bugs:
1088 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1089 overridden by the user.
1091 - Honor PATH_SEPARATOR in various places of the Automake package, for
1094 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1097 - Fix install-sh so it can install the `mv' binary... using `mv'.
1099 - Fix tru64 dependency tracking for libtool objects.
1101 - Work around Exuberant Ctags when creating a TAGS files in a directory
1102 without files to scan but with subdirectories to include.
1104 * Bugs introduced by 1.8:
1106 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1107 not defined in the same conditions as the _LDADD that uses it.
1109 - Do not warn when JAVAROOT is overridden, this is legitimate.
1111 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1113 Bugs fixed in 1.8.3:
1115 * Long-standing bugs:
1117 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1118 or any of the other *dir variables contain a space.
1120 Please note that Automake does not and cannot support spaces in
1121 filenames that are involved during the build. This change affects
1122 only installation paths, so that `make install' does not bomb out
1123 in packages configured with
1124 ./configure --prefix '/c/Program Files'
1126 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1127 POSIXLY_CORRECT is set.
1129 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1130 since Autoconf 2.54, which defines LIBOBJS itself.
1132 - Fix a potential (but unlikely) race condition in parallel elisp
1133 builds. (Introduced in 1.7.3.)
1135 - Do not assume that users override _DEPENDENCIES in all conditions
1136 where Automake will try to define them.
1138 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1139 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1142 This fix also affects the $(mkdir_p) variable defined since
1143 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1144 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1146 - Secure temporary directory creation in `make distcheck'. (PR/413)
1148 - Do not generate two build rules for `parser.h' when the
1149 parser appears in two different conditionals.
1151 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1152 checking. Usually ./configure will not pick this shell; so this
1153 fix only helps cases where the shell is forced to /bin/sh.
1155 * Bugs introduced by 1.8:
1157 - In some situations (hand-written `m4_include's), aclocal would
1158 call the `File::Spec->rel2abs' method, which was only introduced
1159 in Perl 5.6. This new version reestablish support Perl 5.005.
1161 It is likely that the next major Automake releases will require at
1162 least Perl 5.6. Consider upgrading your development environment
1163 if you are still using the five-year-old Perl 5.005.
1165 - Automake would sometimes fail to define rules for targets listed
1166 in variables defined in multiple conditions. For instance on
1172 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1173 `b.$(OBJEXT): b.c' rule.
1175 * New sections in manual:
1177 - Third-Party Makefiles: how to interface third party Makefiles.
1178 - Upgrading: upgrading packages to newer Automake versions.
1179 - Multiple Outputs: handling tools that produce many outputs.
1181 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1185 * A (well known) portability bug slipped in the changes made to
1186 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1187 install anything on Tru64.
1189 * Fix install rules for conditionally built python files. (This never
1192 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1196 * Bugs introduced by 1.8:
1198 - Fix Config.pm import error with old Perl versions (at least
1199 5.005_03). One symptom is that aclocal could not find its macro
1202 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1203 created by `make install' are always world readable, even if the
1204 installer happens to have an overly restrictive umask (e.g. 077).
1205 This was a mistake and has been reverted. There are at least two
1206 reasons why we must not use `-m 0755':
1207 - it causes special bits like SGID to be ignored,
1208 - it may be too restrictive (some setups expect 775 directories).
1210 - Fix aclocal to honor definitions located in files which have been
1211 m4_included manually. aclocal 1.8 had been updated to check
1212 m4_included files for new requirements, but forgot that these
1213 m4_included files can also provide new definitions.
1215 Note that if you have such a setup, we recommend you get rid of
1216 it. In the past, there was a reason to m4_include files manually:
1217 aclocal used to duplicate entire M4 files into aclocal.m4, even
1218 files that were distributed. Some packages were therefore
1219 m4_including the distributed file directly, and playing some
1220 tricks to ensure aclocal would not copy that file to aclocal.m4,
1221 in order to limit the amount of duplication. Since aclocal 1.8.x
1222 will precisely output m4_includes for local M4 files, we recommend
1223 that you clean up your setup, removing all manual m4_includes and
1224 letting aclocal output them.
1226 - Output detailed menus in the Info version if the Automake manual,
1227 so that Emacs can locate the indexes.
1229 - configure.ac and configure were listed twice in DIST_COMMON (an
1230 internal variable where Automake lists configury files to
1231 distribute). This was harmless, but unaesthetic.
1233 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1234 This was an issue only in the Automake package itself, not in
1237 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1238 DEST:SRC. This was wrong, as some packages do
1239 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1242 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1243 argument. This caused two kinds of failures:
1244 - Rules installing data in a conditionally defined directory
1245 failed when that directory was undefined. In this case no
1246 argument was supplied.
1247 - `make installdirs' failed, because several directories were
1248 passed to $(mkdir_p). This was an issue only on platform
1249 were $(mkdir_p) is implemented with `install-sh -d'.
1250 $(mkdir_p) as been changed to accept 0 or more arguments, as
1253 * Long-standing bugs:
1255 - Fix an unexpected diagnostic occurring when users attempt
1256 to override some internal variables that Automake appends to.
1258 - aclocal now scans configure.ac for macro definitions (PR/319).
1260 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1261 distributes files which are outside itself (this usually occurs
1262 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1263 from a parent package), then `make distcheck' fails due to an
1264 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1265 (tests/subpkg2.test failure)
1267 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1268 In a VPATH-build configuration, `make install' would install
1269 nobase_ files to wrong locations.
1271 - Fix a Perl `uninitialized value' diagnostic occurring when
1272 automake complains that a Texinfo file does not have a
1273 @setfilename statement.
1275 - Erase config.status.lineno during `make distclean'. This file
1276 can be created by config.status. Automake already knew about
1277 configure.lineno, but forgot config.status.lineno.
1279 - Distribute all files, even those which are built and installed
1280 conditionally. This change affects files listed in conditionally
1281 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1282 as well as those listed in conditionally defined dist_*_DATA,
1283 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1285 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1286 doesn't conform to POSIX.
1288 - Normalize help strings for configure variables and options added
1293 - Check for python2.4 in AM_PATH_PYTHON.
1295 * Spurious failures in test suite:
1297 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1298 tests/ltconv.test: fix failures with CVS Libtool.
1299 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1300 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1301 fix failures with old Texinfo versions.
1303 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1309 - The NEWS file is more verbose.
1313 - Autoconf 2.58 or greater is required.
1317 - Default source file names in the absence of a _SOURCES declaration
1318 are made by removing any target extension before appending `.c', so
1319 to make the libtool module `foo.la' from `foo.c', you only need to
1322 lib_LTLIBRARIES = foo.la
1323 foo_la_LDFLAGS = -module
1325 For backward compatibility, foo_la.c will be used instead of
1326 foo.c if this file exists or is the explicit target of a rule.
1327 However -Wobsolete will warn about this deprecated naming.
1329 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1330 of being hard-coded in each $(AR) invocation, so they can be
1331 substituted from configure.ac. This has been requested by people
1332 dealing with non-POSIX ar implementations.
1334 - New warning option: -Woverride. This will warn about any user
1335 target or variable definitions which override Automake
1338 - Texinfo rules back up and restore info files when makeinfo fails.
1340 - Texinfo rules now support the `html' target.
1341 Running this requires Texinfo 4.0 or greater.
1343 `html' is a new recursive target, so if your package mixes
1344 hand-crafted `Makefile.in's with Automake-generated
1345 `Makefile.in's, you should adjust the former to support (or
1346 ignore) this target so that `make html' recurses successfully. If
1347 you had a custom `html' rule in your `Makefile.am', it's better to
1348 rename it as `html-local', otherwise your rule will override
1349 Automake's new rule (you can check that by running `automake
1350 -Woverride') and that will stop the recursion to subdirectories.
1352 Last but not least, this `html' rule is declared PHONY, even when
1353 overridden. Fortunately, it appears that few packages use a
1354 non-PHONY `html' rule.
1356 - Any file which is m4_included from configure.ac will appear as a
1357 configure and Makefile.in dependency, and will be automatically
1360 - The rules for rebuilding Makefiles and Makefile.ins will now
1361 rebuild all Makefiles and all Makefile.ins at once when one of
1362 configure's dependencies has changed. This is considerably faster
1363 than previous implementations, where config.status and automake
1364 were run separately in each directory (this still happens when you
1365 change a Makefile.am locally, without touching configure.ac or
1366 friends). Doing this also solves a longstanding issue: these
1367 rebuild rules failed to work when adding new directories to the
1368 tree, forcing you to run automake manually.
1370 - For similar reasons, the rules to rebuild configure,
1371 config.status, and aclocal.m4 are now defined in all directories.
1372 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1373 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1374 should better define them in all directories. This is easily done
1375 using an AC_SUBST (make sure you prefix these dependencies with
1376 $(top_srcdir) since this variable will appear at different
1377 levels of the build tree).
1379 - aclocal will now use `m4_include' instead of copying local m4
1380 files into aclocal.m4. (Local m4 files are those you ship with
1381 your project, other files will be copied as usual.)
1383 Because m4_included files are automatically distributed, it means
1384 for most projects there is no point in EXTRA_DISTing the list of
1385 m4 files which are used. (You can probably get rid of
1386 m4/Makefile.am if you had one.)
1388 - aclocal will avoid touching aclocal.m4 when possible, so that
1389 Autom4te's cache isn't needlessly invalidated. This behavior can
1390 be switched off with the new `--force' option.
1392 - aclocal now uses Autoconf's --trace to detect macros which are
1393 actually used and will no longer include unused macros simply
1394 because they where mentioned. This was often the case for macros
1395 called conditionally.
1397 - New options no-dist and no-dist-gzip.
1399 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1400 py-compile, and ylwrap, now all understand --version and --help.
1402 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1403 links as part of the distclean target and including source files in
1406 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1407 argument. The latter can be used to override the default behavior
1408 (which is to abort).
1410 - Automake will exit with $? = 63 on version mismatch. (So does
1411 Autoconf 2.58) missing knows this, and in this case it will
1412 emulate the tools as if they were absent. Because older versions
1413 of Automake and Autoconf did not use this exit code, this change
1414 will only be useful in projects generated with future versions of
1417 - When using AC_CONFIG_FILES with multiple input files, Automake
1418 generates the first ".in" input file for which a ".am" exists.
1419 (Former versions would try to use only the first input file.)
1421 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1422 idiom to disable byte-compilation of lisp_LISP files, it is
1423 recommended that you switch to using lisp_DATA. Note that
1424 this is not strictly equivalent: lisp_DATA will install elisp
1425 files even if emacs is not installed, while *_LISP do not
1426 install anything unless emacs is found.
1428 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1429 available. This selection is achieved through the Makefile
1430 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1431 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1432 `$(install_sh) -m 0755 -d'.
1436 - Because `mkdir -p' is available on most platforms, and we can use
1437 `install-sh -d' when it is not, the use of the mkinstalldirs
1438 script is being phased out. `automake --add-missing' no longer
1439 installs it, and if you remove mkinstalldirs from your package,
1440 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1442 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1443 gettextize and autopoint will install it when needed. Automake
1444 will continue to define the $(mkinstalldirs) and to distribute
1445 mkinstalldirs when this script is in the source tree.
1447 - AM_PROG_CC_STDC is now empty. The content of this macro was
1448 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1449 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1450 renaming should be safe, even if you have to support several,
1451 versions of Automake, because AC_PROG_CC defines this variable
1452 since Autoconf 2.54.)
1454 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1455 variable to override the aclocal.m4 dependencies computed
1456 (inaccurately) by older versions of Automake. Because Automake
1457 now tracks configure's m4 dependencies accurately (see m4_include
1458 above), the use of ACLOCAL_M4_SOURCES should be considered
1459 obsolete and will be flagged as such when running `automake
1464 - Defining programs conditionally using Automake conditionals no
1465 longer leads to a combinatorial explosion. The following
1466 construct used to be troublesome when used with dozens of
1481 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1483 - Due to implementation constraints, previous versions of Automake
1484 proscribed multiple conditional definitions of some variables
1494 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1495 This restriction has been lifted, and these variables now
1496 support multiple conditional definitions as do other variables.
1498 - Cleanup the definitions of $(distdir) and $(top_distdir).
1499 $(top_distdir) now points to the root of the distribution
1500 directory created during `make dist', as it did in Automake 1.4,
1501 not to the root of the build tree as it did in intervening
1502 versions. Furthermore these two variables are now only defined in
1503 the top level Makefile, and passed to sub-directories when running
1506 - The --no-force option now correctly checks the Makefile.in's
1507 dependencies before deciding not to update it.
1509 - Do not assume that make files are called Makefile in cleaning rules.
1511 - Update .info files in the source tree, not in the build tree. This
1512 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1513 used to update these files in the build tree (previous versions did
1514 it in the source tree too), and it caused several problems, varying
1515 from mere annoyance to portability issues.
1517 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1518 when --add-missing and --force-missing are used. For backward
1519 compatibility --add-missing will continue to install COPYING (in
1520 `gnu' strictness) when none of these three files exist, but this
1521 use is deprecated: you should better choose a license yourself and
1522 install it once for all in your source tree (and in your code
1525 - Fix ylwrap so that it does not overwrite header files that haven't
1526 changed, as the inline rule already does.
1528 - User-defined rules override automake-defined rules for the same
1529 targets, even when rules do not have commands. This is not new
1530 (and was documented), however some of the automake-generated
1531 rules have escaped this principle in former Automake versions.
1532 Rules for the following targets are affected by this fix:
1534 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1535 info, info-am, install-data-am, install-exec-am, install-info,
1536 install-info-am, install-man, installcheck-am, maintainer-clean,
1537 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1538 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1540 Practically it means that an attempt to supplement the dependencies
1541 of some target, as in
1543 clean: my-clean-rule
1545 will now *silently override* the automake definition of the
1546 rule for this target. Running `automake -Woverride' will diagnose
1547 all such overriding definitions.
1549 It should be noted that almost all these targets support a *-local
1550 variant that is meant to supplement the automake-defined rule
1551 (See node `Extending' in the manual). The above rule should
1554 clean-local: my-clean-rule
1556 These *-local targets have been documented since at least
1557 Automake 1.2, so you should not fear the change if you have
1558 to support multiple automake versions.
1562 - The Automake manual is now distributed under the terms of the GNU FDL.
1564 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1566 - core dumps are no longer removed by the cleaning rules. There are
1567 at least three reasons for this:
1568 1. These files should not be created by any build step,
1569 so their removal do not fit any of the cleaning rules.
1570 Actually, they may be precious to the developer.
1571 2. If such file is created during a build, then it's clearly a
1572 bug Automake should not hide. Not removing the file will
1573 cause `make distcheck' to complain about its presence.
1574 3. Operating systems have different naming conventions for
1575 core dump files. A core file on one system might be a
1576 completely legitimate data file on another system.
1578 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1579 defined by Automake. This means that any definition in the
1580 environment will be used, unless overridden in the Makefile.am or
1581 on the command line. The old behavior, where these variables were
1582 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1583 AC_ARG_VARing each variable from configure.ac.
1585 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1586 documented. (The is not a new feature, these variables have
1587 been there since at least Automake 1.4.)
1589 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1591 Bugs fixed in 1.7.9:
1592 * Fix install-strip to work with nobase_ binaries.
1593 * Fix renaming of #line directives in ylwrap.
1594 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1596 Bugs fixed in 1.7.8:
1597 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1598 * Fix detection of Debian's install-info, broken since version 1.5.
1599 (Debian bug #213524).
1600 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1601 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1603 Bugs fixed in 1.7.7:
1604 * The implementation of automake's --no-force option is unreliable,
1605 so this option is ignored in this version. A real fix will appear in
1606 Automake 1.8. (Debian Bug #206299)
1607 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1608 argument is given. (PR/399)
1609 * Do not warn about leading `_' in variable names, even with -Wportability.
1610 * Support user redefinitions of TEXINFO_TEX.
1611 * depcomp: support AIX Compiler version 6.
1612 * Fix missing rebuilds during `make dist' with BSD make.
1613 (Could produce tarballs containing out-of-date files.)
1614 * Resurrect multilib support.
1615 * Noteworthy manual updates:
1616 - Extending aclocal: how to write m4 macros that won't trigger warnings
1618 - A Shared Library: Rewrite and split into subsections.
1620 Bugs fixed in 1.7.6:
1621 * Fix depcomp's icc mode for ICC 7.1.
1622 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1623 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1624 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1625 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1626 * Remove Latin-1 characters from elisp-comp.
1627 * Update the manual's @dircategory to match the Free Software Directory.
1629 Bugs fixed in 1.7.5:
1630 * Update install-sh's license to remove an advertising clause.
1631 (Debian bug #191717)
1632 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1633 that caused invalid Makefile.ins to be generated.
1634 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1635 * New FAQ entry: renamed objects.
1637 Bugs fixed in 1.7.4:
1638 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1639 the Emacs implementation)
1640 * Fix output of aclocal.m4 dependencies in subdirectories.
1641 * Use `mv -f' instead of `mv' in fastdep rules.
1642 * Upgrade mdate-sh to work on OS/2.
1643 * Don't byte-compile elisp files when ELCFILES is set empty.

1651 * Minor documentation fixes.
1653 Bugs fixed in 1.7.3:
1654 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1655 * Query distutils for `pythondir' and `pythonexecdir', instead of
1656 using an hardcoded path. This should allow builds on 64-bit
1657 distributions that usually use lib64/ instead of lib/.
1658 * AM_PATH_PYTHON will also search for python2.3.
1659 * elisp files are now built all at once instead of one by one. Besides
1660 incurring a speed-up, this is required to support interdependent elisp files.
1661 * Support for DJGPP:
1662 - `make distcheck' will now work in `_inst/' and `_build' instead
1663 of `=inst/' and `=build/'
1664 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1665 - install/uninstall `*.i[0-9][0-9]'-style info files
1666 - more changes that affect only the Automake package (not its output)
1667 * Fix some incompatibilities with upcoming perl-5.10.
1668 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1669 PACKAGE and VERSION.
1671 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1672 is troublesome with gcc and Solaris compilers. (PR/385)
1673 - makedepend mode: work with Libtool. (PR/385 too)
1675 * better support for unusual gettext setups, such as multiple po/ directories
1677 - Flag missing po/ and intl/ directories as warnings, not errors.
1678 - Disable these warnings if po/ does not exist.
1679 * Noteworthy manual updates:
1681 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1683 - Document `AM_YFLAGS = -d'. (PR/382)
1685 Bugs fixed in 1.7.2:
1686 * Fix installation and uninstallation of Info files built in subdirectories.
1687 * Do not run `./configure --with-included-gettext' during `make distcheck'
1688 if AM_GNU_GETTEXT([external]) is used.
1689 * Correctly uninstall renamed man pages.
1690 * Do not strip escaped newline in variables defined in one condition
1691 and augmented in another condition.
1692 * Fix ansi2knr rules for LIBOBJS sources.
1693 * Clean all known Texinfo index files, not only those which appear to
1694 be used, because we cannot know which indexes are used in included files.
1695 (PR/375, Debian Bug #168671)
1696 * Honor only the first @setfilename seen in a Texinfo file.
1697 * Treat "required file X not found" diagnostics as errors (exit status 1).
1698 * Don't complain that a required file is not found when it is a Makefile
1700 * Don't use single suffix inference rules when building `.info'-less
1701 Info files, for the sake of Solaris make.
1702 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1703 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1704 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1705 * Fix building of deansified files from subdirectories. (PR/370)
1706 * Add missing `fi' in the .c->.obj rules.
1707 * Improve install-sh to work even when names contain spaces or certain
1708 (but not all) shell metachars.
1709 * Fix the following spurious failures in the test suite:
1710 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1711 * Noteworthy manual updates:
1712 - Augment the section about BUILT_SOURCES.
1713 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1715 Bugs fixed in 1.7.1:
1716 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1718 * Aclocal should now recognize macro names containing parentheses, e.g.
1719 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1720 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1722 * Install Python files even if they were built. (PR/369)
1723 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1724 version might not be defined in the latter. (PR/358)
1725 * Reorder arguments passed to a couple of commands, so things works
1726 when POSIXLY_CORRECT=1.
1727 * Fix a regex that can cause Perl to segfault on large input.
1729 * Fix distribution of packages that have some sources defined conditionally,
1730 as in the `Conditional compilation using Automake conditionals' example
1732 * Fix spurious test suite failures on IRIX.
1733 * Don't report a required variable as undefined if it has been
1734 defined conditionally for the "right" conditions.
1735 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1736 `make distcheck' fails.
1737 * Fix distribution of included Makefile fragment, so we don't create
1738 spurious directories in the distribution. (PR/366)
1739 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1742 * Autoconf 2.54 is required.
1743 * `aclocal' and `automake' will no longer warn about obsolete
1744 configure macros. This is done by `autoconf -Wobsolete'.
1745 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1746 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1747 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1748 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1749 `configure.ac' for you.
1750 * Support for per-program and per-library `_CPPFLAGS'.
1751 * New `ctags' target (builds CTAGS files).
1752 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1753 (see `automake --help' or the manual for a list of them).
1754 * Honor the WARNINGS environment variable.
1755 * Omit the call to depcomp when using gcc3: call the compiler directly.
1756 * A new option, std-options, tests that programs support --help and --version
1757 when `make installcheck' is run. This is enabled by --gnits.
1758 * Texinfo rules now support the `ps' and `pdf' targets.
1759 * Info files are now created in the build directory, not the source directory.
1760 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1762 * `make distcheck' will enforce DESTDIR support by attempting
1764 * `+=' can be used in conditionals, even if the augmented variable
1765 was defined for another condition.
1766 * Makefile fragments (inserted with `include') are always distributed.
1767 * Use Autoconf's --trace interface to inspect configure.ac and get
1768 a more accurate view of it.
1769 * Add support for extending aclocal's default macro search path
1770 using a `dirlist' file within the aclocal directory.
1771 * automake --output-dir is deprecated.
1772 * The part of the distcheck target that checks whether uninstall actually
1773 removes all installed files has been moved in a separate target,
1774 distuninstallcheck, so it can be overridden easily.
1778 * Support for AM_INIT_GETTEXT([external])
1779 * Bug fixes, including:
1780 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1781 - nobase_ programs and scripts honor --program-transform correctly.
1782 - Erase configure.lineno during `make distclean'.
1783 - Erase YACC and LEX outputs during `make maintainer-clean'.
1786 * Many bug fixes, including:
1787 - Requiring the current version works.
1788 - Fix "$@" portability issues (for Zsh).
1789 - Fix output of dummy dependency files in presence of post-processed
1791 - Don't compute dependencies in background to avoid races with libtool.
1792 - Fix handling of _OBJECTS variables for targets sharing source variables.
1793 - Check dependency mode for Java when AM_PROG_GCJ is used.
1796 * automake --output-dir is deprecated
1797 * Many bug fixes, including:
1798 - Don't choke on AM_LDFLAGS definitions.
1799 - Clean libtool objects from subdirectories.
1800 - Allow configure variables with reserved suffix and unknown prefix
1801 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1802 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1805 * Autoconf 2.52 is required.
1806 * automake no longer run libtoolize.
1807 This is the job of autoreconf (from GNU Autoconf).

1809 * `dist-gzip' generates the Gzip tar file only.
1810 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1811 explosion. Makefile.in's keep a reasonable size.

1817 * Support for dot-less extensions in suffix rules.
1818 * The part of the distcheck target that checks whether distclean actually
1819 cleans all built files has been moved in a separate target, distcleancheck,
1820 so it can be overridden easily.

1829 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1830 (Note that "pkgname" is not "tarname", see the manual for details.)
1831 It is also possible to pass a list of global Automake options as
1832 first argument to this new form of AM_INIT_AUTOMAKE.
1833 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1834 to be a real assembler.
