1 * WARNING: Future backward-incompatibilities!
3 - The '--acdir' option of aclocal is deprecated, and will probably
4 be removed in the next major Automake release (1.13). You should
5 use the options '--automake-acdir' and '--system-acdir' instead
6 (which have been introduced in Automake 1.11.2).
8 - The exact order in which the directories in the aclocal macro
9 search path are looked up is probably going to be changed in the
10 next Automake release (1.13).
14 * Obsolete features removed:
16 - Support for automatic de-ANSI-fication has been removed.
18 - The support for the "obscure" multilib feature has been removed
19 from Automake core (but remains available in the 'contrib/'
20 directory of the Automake distribution).
22 - Support for ".log -> .html" conversion and the check-html and
23 recheck-html targets has been removed from Automake core (but
24 remains available in the 'contrib/' directory of the Automake
27 - The deprecated 'lzma' compression format for distribution archives
28 has been removed, in favor of 'xz' and 'lzip'.
30 - The obsolete AM_WITH_REGEX macro has been removed.
32 - The long-deprecated options '--output-dir', '--Werror' and
33 '--Wno-error' have been removed.
35 - The chapter on the history of Automake has been moved out of the
36 reference manual, into a new dedicated Texinfo file.
40 - New 'cscope' target to build a cscope database for the source tree.
42 * Changes to Automake-generated testsuite harnesses:
44 - The new automake option 'serial-tests' has been introduced. It can
45 be used to explicitly instruct automake to use the older serial
46 testsuite harness. This is still the default at the moment, but it
47 might change in future versions.
49 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
50 and unexpected or internal error, or a failure to set up the test case
51 scenario) have their outcome reported as an 'ERROR' now. Previous
52 versions of automake reported such an outcome as a 'FAIL' (the only
53 difference with normal failures being that hard errors were counted
54 as failures even when the test originating them was listed in
57 - The testsuite summary displayed by the parallel-test harness has a
58 completely new format, that always list the numbers of passed, failed,
59 xfailed, xpassed, skipped and errored tests, even when these numbers
60 are zero (but using smart coloring when the color-tests option is in
63 - The default testsuite driver offered by the 'parallel-tests' option is
64 now implemented (partly at least) with the help of automake-provided
65 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
66 on code in the generated Makefile.in.
67 This has two noteworthy implications. The first one is that projects
68 using the 'parallel-tests' option should now either run automake with
69 the '--add-missing' option, or manually copy the 'test-driver' script
70 into their tree. The second, and more important, implication is that
71 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
72 not be used anymore to define a test runner, and the command specified
73 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
74 program or script. For example, this is still a valid usage (albeit
78 if test -n '$(STRICT_TESTS)'; then \
83 LOG_COMPILER = $(SHELL) $$maybe_errexit
85 while this is not anymore:
88 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
93 run_with_perl_or_shell () \
95 if grep -q '^#!.*perl' $$1; then
101 LOG_COMPILER = run_with_per_or_shell
103 - The package authors can now use customary testsuite drivers within
104 the framework provided by the 'parallel-tests' testsuite harness.
105 Consistently with the existing syntax, this can be done by defining
106 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
108 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
109 to redirect/define file descriptors used by the test scripts.
111 - The parallel-tests harness generates now, in addition the '.log' files
112 holding the output produced by the test scripts, a new set of '.trs'
113 files, holding "metadata" derived by the execution of the test scripts;
114 among such metadata are the outcomes of the test cases run by a script.
116 - Initial and still experimental support for the TAP test protocol is
119 * Changes to Yacc and Lex support:
121 - C source and header files derived from non-distributed Yacc and/or
122 Lex sources are now removed by a simple "make clean" (while they were
123 previously removed only by "make maintainer-clean").
125 - Slightly backward-incompatible change, relevant only for use of Yacc
126 with C++: the extensions of the header files produced by the Yacc
127 rules are now modelled after the extension of the corresponding
128 sources. For example, yacc files named "foo.y++" and "bar.yy" will
129 produce header files named "foo.h++" and "bar.hh" respectively, where
130 they would have previously produced header files named simply "foo.h"
131 and "bar.h". This change offers better compatibility with 'bison -o'.
133 * Miscellaneous changes:
135 - Automake has a new option '--print-libdir' that prints the path of the
136 directory containing the Automake-provided scripts and data files.
138 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
140 - Automake can now generate silenced rules for texinfo outputs.
142 - Some auxiliary files that are automatically distributed by Automake
143 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
144 C sources) might now be listed in the DIST_COMMON variable in many
145 Makefile.in files, rather than in the top-level one.
147 - Messages of types warning or error from 'automake' and 'aclocal'
148 are now prefixed with the respective type, and presence of -Werror
151 - Automake's early configure-time sanity check now tries to avoid
152 sleeping for a second, which slowed down cached configure runs
153 noticeably. In that case, it will check back at the end of the
154 configure script to ensure that at least one second has passed, to
155 avoid time stamp issues with makefile rules rerunning autotools
158 - For programs and libraries, automake now detect EXTRA_foo_DEPENDENCIES
159 and adds them to the normal list of dependencies, but without
160 overwriting the foo_DEPENDENCIES variable, which is normally computed
163 - The warnings in the category 'extra-portability' are now enabled by
164 '-Wall'. In previous versions, one has to use '-Wextra-portability'
169 - Various minor bugfixes for recent or long-standing bugs.
171 * Bugs introduced by 1.11:
173 - The AM_COND_IF macro also works if the shell expression for the
174 conditional is no longer valid for the condition.
176 - The automake-provided parallel testsuite harness does not fail anymore
177 with BSD make used in parallel mode when there are test scripts in a
178 subdirectory, like in:
180 TESTS = sub/foo.test sub/bar.test
182 * Long-standing bugs:
184 - Automake's own build system finally have a real "installcheck" target.
186 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
187 now automatically distributed also if the directory of the auxiliary
188 files coincides with the top-level directory.
190 - Automake now detects the presence of the '-d' flag in the various
191 '*YFLAGS' variables even when their definitions involve indirections
192 through other variables, such as in:
194 AM_YFLAGS = $(foo_opts)
196 - Automake now complains if a '*YFLAGS' variable has any conditional
197 content, not only a conditional definition.
199 - Explicit enabling and/or disabling of Automake warning categories
200 through the '-W...' options now always takes precedence over the
201 implicit warning level implied by Automake strictness (foreign, gnu
202 or gnits), regardless of the order in which such strictness and
203 warning flags appear. For example, a setting like:
204 AUTOMAKE_OPTIONS = -Wall --foreign
205 will cause the warnings in category 'portability' to be enabled, even
206 if those warnings are by default disabled in 'foreign' strictness.
208 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
212 * WARNING: Future backward-incompatibilities!
214 - The obsolescent AM_WITH_REGEX macro has been deprecated, since the
215 GNU rx library has been decommissioned.
217 - The `lzma' compression format for distribution archives has been
218 deprecated in favor of `xz' and `lzip'.
220 * Miscellaneous changes:
222 - Automake's own build system is more silent by default, making use of
223 the 'silent-rules' option.
225 - The master copy of the `gnupload' script is now maintained in gnulib,
228 - The `missing' script doesn't try to wrap calls to `tar' anymore.
230 - "make dist" doesn't wrap `tar' invocations with the `missing' script
231 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
232 shouldn't be using BTW ;-) does not invoke the missing script anymore
233 to wrap tar, but simply invokes the `tar' program itself.
235 - "make dist" can now create lzip-compressed tarballs.
237 - In the Automake info documentation, the Top node and the nodes about
238 the invocation of the automake and aclocal programs have been renamed;
239 now, calling "info automake" will open the Top node, while calling
240 "info automake-invocation" and "info aclocal-invocation" will access
241 the nodes about the invocation of respectively automake and aclocal.
243 - Automake is now distributed as a gzip-compressed and an xz-compressed
244 tarball. Previously, bzip2 was used instead of xz.
246 - The last relics of Python 1.5 support have been removed from the
247 AM_PATH_PYTHON macro.
249 Bugs fixed in 1.11.3:
251 * Long-standing bugs:
253 - The "deleted header file problem" for *.am files is avoided by stub
254 rules. This allows `make' to trigger a rerun of `automake' also if
255 some previously needed `.am' file has been removed.
257 - The `silent-rules' option now generates working makefiles even
258 for the uncommon `make' implementations that do not support the
259 nested-variables extension to POSIX 2008. For such `make'
260 implementations, whether a build is silent is determined at
261 configure time, and cannot be overridden at make time with
262 `make V=0' or `make V=1'.
264 - Vala support now works better in VPATH setups.
266 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
270 * Changes to aclocal:
272 - The `--acdir' option is deprecated. Now you should use the new options
273 `--automake-acdir' and `--system-acdir' instead.
275 - The `ACLOCAL_PATH' environment variable is now interpreted as a
276 colon-separated list of additional directories to search after the
277 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
278 and before the system acdir (by default ${prefix}/share/aclocal).
280 * Miscellaneous changes:
282 - The Automake support for automatic de-ANSI-fication has been
285 - The `lzma' compression scheme and associated automake option `dist-lzma'
286 is obsoleted by `xz' and `dist-xz' due to upstream changes.
288 - You may adjust the compression options used in dist-xz and dist-bzip2.
289 The default is now merely -e for xz, but still -9 for bzip; you may
290 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
291 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
293 - The `compile' script now converts some options for MSVC for a better
294 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
296 - The py-compile script now accepts empty arguments passed to the options
297 `--destdir' and `--basedir', and complains about unrecognized options.
298 Moreover, a non-option argument or a special `--' argument terminates
301 - A developer that needs to pass specific flags to configure at "make
302 distcheck" time can now, and indeed is advised to, do so by defining
303 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
304 instead of the old DISTCHECK_CONFIGURE_FLAGS.
305 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
306 user; still, the old Makefile.am files that used to define it will
307 still continue to work as before.
309 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
310 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
311 This new macro is required for LIBRARIES and LTLIBRARIES when automake
312 is run with -Wextra-portability and -Werror.
314 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
315 file generated by automake-provided rules by defining the special make
316 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
318 - The `install-info' rule can now be instructed not to create/update
319 the `${infodir}/dir' file, by exporting the new environment variable
320 `AM_UPDATE_INFO_DIR' to the value "no".
322 Bugs fixed in 1.11.2:
324 * Bugs introduced by 1.11.2:
326 - Automake now correctly recognizes the prefix/primary combination
327 `pkglibexec_SCRIPTS' as valid.
329 * Bugs introduced by 1.11:
331 - The parallel-tests driver no longer produces erroneous results with
332 Tru64/OSF 5.1 sh upon unreadable log files.
334 - The `parallel-tests' test driver does not report spurious successes
335 when used with concurrent FreeBSD make (e.g., "make check -j3").
337 - When the parallel-tests driver is in use, automake now explicitly
338 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
339 instead of issuing confusing and apparently unrelated error messages
340 (e.g., "non-POSIX variable name", "bad characters in variable name",
341 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
342 silently producing broken `Makefile.in' files.
344 - The `silent-rules' option now truly silences all compile rules, even
345 when dependency tracking is disabled. Also, when `silent-rules' is
346 not used, `make' output no longer contains spurious backslash-only
347 lines, thus once again matching what Automake did before 1.11.
349 - The AM_COND_IF macro also works if the shell expression for the
350 conditional is no longer valid for the condition.
352 * Long-standing bugs:
354 - The order of Yacc and Lex flags is fixed to be consistent with other
355 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
356 $(LFLAGS), so that the user variables override the developer variables.
358 - "make distcheck" now correctly complains also when "make uninstall"
359 leaves one and only one file installed in $(prefix).
361 - A "make uninstall" issued before a "make install", or after a mere
362 "make install-data" or a mere "make install-exec" does not spuriously
365 - Automake now warns about more primary/directory invalid combinations,
366 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
368 - Rules generated by Automake now try harder to not change any files when
369 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
370 Yacc source files and the rule to update config.h.
372 - Several scripts and the parallel-tests testsuite driver now exit with
373 the right exit status upon receiving a signal.
375 - A per-Makefile.am setting of -Werror does not erroneously carry over
376 to the handling of other Makefile.am files.
378 - The code for automatic dependency tracking works around a Solaris
379 make bug triggered by sources containing repeated slashes when the
380 `subdir-objects' option was used.
382 - The makedepend and hp depmodes now work better with VPATH builds.
384 - Java sources specified with check_JAVA are no longer compiled for
385 "make all", but only for "make check".
387 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
388 and error out if `javadir' is undefined, instead of silently producing
389 a broken Makefile.in.
391 - aclocal and automake now honour the configure-time definitions of
392 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
394 - The `install-info' recipe no longer tries to guess whether the
395 `install-info' program is from Debian or from GNU, and adaptively
396 change its behaviour; this has proven to be frail and easy to
399 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
401 Bugs fixed in 1.11.1:
403 - Lots of minor bugfixes.
405 * Bugs introduced by 1.11:
407 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
408 trailing white space in the test list (`TESTS = foo $(EMPTY)').
410 * Long standing bugs:
412 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
413 even if the `--prefix' argument pointed outside of a system directory.
414 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
415 `get_python_lib' function if it points outside the configured prefix,
416 unless the `--prefix' argument was either `/usr' or below `/System'.
418 - The testsuite does not try to change the mode of `ltmain.sh' files from
419 a Libtool installation (symlinked to test directories) any more.
421 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
422 tools are preferred in a cross-compile setup.
424 - The distribution is tarred up with mode 755 now by the `dist*' targets.
425 This fixes a race condition where untrusted users could modify files
426 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
427 build directory was world-searchable. This is CVE-2009-4029.
429 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
433 * Version requirements:
435 - Autoconf 2.62 or greater is required.
437 * Changes to aclocal:
439 - The autoconf version check implemented by aclocal in aclocal.m4
440 (and new in Automake 1.10) is degraded to a warning. This helps
441 in the common case where the Autoconf versions used are compatible.
443 * Changes to automake:
445 - The automake program can run multiple threads for creating most
446 Makefile.in files concurrently, if at least Perl 5.7.2 is available
447 with interpreter-based threads enabled. Set the environment variable
448 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
449 enable this experimental feature.
451 * Changes to Libtool support:
453 - Libtool generic flags are now passed to the install and uninstall
456 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
457 config.lt is removed correctly now.
461 - subdir-object mode works now with Fortran (F77, FC, preprocessed
462 Fortran, and Ratfor).
464 - For files with extension .f90, .f95, .f03, or .f08, the flag
465 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
467 - Files with extension .sx are also treated as preprocessed assembler.
469 - The default source file extension (.c) can be overridden with
470 AM_DEFAULT_SOURCE_EXT now.
472 - Python 3.0 is supported now, Python releases prior to 2.0 are no
475 - AM_PATH_PYTHON honors python's idea about the site directory.
477 - There is initial support for the Vala programming language, when using
480 * Miscellaneous changes:
482 - Automake development is done in a git repository on Savannah now, see
484 http://git.sv.gnu.org/gitweb/?p=automake.git
486 A read-only CVS mirror is provided at
488 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
489 checkout -d automake HEAD
491 - "make dist" can now create xz-compressed tarballs,
492 as well as (deprecated?) lzma-compressed tarballs.
494 - `automake --add-missing' will by default install the GPLv3 file as
495 COPYING if it is missing. It will also warn that the license file
496 should be added to source control. Note that Automake will never
497 overwrite an existing COPYING file, even when the `--force-missing'
500 - The manual is now distributed under the terms of the GNU FDL 1.3.
502 - Automake ships and installs man pages for automake and aclocal now.
504 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
506 - install-sh supports -C, which does not update the installed file
507 (and its time stamps) if the contents did not change.
509 - The `gnupload' script has been revamped.
511 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
513 - The targets `install' and `uninstall' are more efficient now, in that
514 for example multiple files from one Automake variable such as
515 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
516 invocation if they do not have to be renamed.
518 Both install and uninstall may sometimes enter (`cd' into) the target
519 installation directory now, when no build-local scripts are used.
521 Both install and uninstall do not fail anymore but do nothing if an
522 installation directory variable like `bindir' is set to the empty string.
524 For built-in rules, `make install' now fails reliably if installation
525 of a file failed. Conversely, `make uninstall' even succeeds when
526 issued multiple times.
528 These changes may need some adjustments from users: For example,
529 some `install' programs refuse to install multiple copies of the
530 same file in one invocation, so you may need to remove duplicate
531 entries from file lists.
533 Also, within one set of files, say, nobase_data_DATA, the order of
534 installation may be changed, or even unstable among different hosts,
535 due to the use of associative arrays in awk. The increased use of
536 awk matches a similar move in Autoconf to provide for better scaling.
538 Further, most undocumented per-rule install command variables such as
539 binSCRIPT_INSTALL have been removed because they are not needed any
540 more. Packages which use them should be using the appropriate one of
541 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
542 counterpart, depending on the type of files and the need for automatic
543 target directory creation.
545 - The "deleted header file problem" for *.m4 files is avoided by
546 stub rules. This allows `make' to trigger a rerun of `aclocal'
547 also if some previously needed macro file has been removed.
549 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
550 an otherwise up to date tree.
552 - The `color-tests' option causes colored test result output on terminals.
554 - The `parallel-tests' option enables a new test driver that allows for
555 parallel test execution, inter-test dependencies, lazy test execution
556 for unit-testing, re-testing only failed tests, and formatted result output
557 as RST (reStructuredText) and HTML. Enabling this option may require some
558 changes to your test suite setup; see the manual for details.
560 - The `silent-rules' option enables Linux kernel-style silent build output.
561 This option requires the widely supported but non-POSIX `make' feature
562 of recursive variable expansion, so do not use it if your package needs
563 to build with `make' implementations that do not support it.
565 To enable less verbose build output, the developer has to use the Automake
566 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
567 macro. The user may then set the default verbosity by passing the
568 `--enable-silent-rules' option to `configure'. At `make' run time, this
569 default may be overridden using `make V=0' for less verbose, and `make V=1'
570 for backward-compatible verbose output.
572 - New prefix `notrans_' for manpages which should not be transformed
573 by --program-transform.
575 - New macro AM_COND_IF for conditional evaluation and conditional
578 - For AC_CONFIG_LINKS, if source and destination are equal, do not
579 remove the file in a non-VPATH build. Such setups work with Autoconf
582 - AM_MAINTAINER_MODE now allows for an optional argument specifying
585 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
586 useful especially for multi-line values.
588 - Automake's early configure-time sanity check now diagnoses an
589 unsafe absolute source directory name and makes configure fail.
591 - The Automake macros and rules cope better with whitespace in the
592 current directory name, as long as the relative path to `configure'
593 does not contain whitespace. To this end, the values of `$(MISSING)'
594 and `$(install_sh)' may contain suitable quoting, and their expansion
595 might need `eval'uation if used outside of a makefile. These
596 undocumented variables may be used in several documented macros such
597 as $(AUTOCONF) or $(MAKEINFO).
601 * Long-standing bugs:
603 - Fix aix dependency tracking for libtool objects.
605 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
606 unnecessary use of the `compile' script.
608 - For nobase_*_LTLIBRARIES with nonempty directory components, the
609 correct `-rpath' argument is used now.
611 - `config.status --file=Makefile depfiles' now also works with the
612 extra quoting used internally by Autoconf 2.62 and newer
613 (it used to work only without the `--file=' bit).
615 - The `missing' script works better with versioned tool names.
617 - Semantics for `missing help2man' have been revamped:
619 Previously, if `help2man' was not present, `missing help2man' would have
620 the following semantics: if some man page was out of date but present, then
621 a warning would be printed, but the exit status was 0. If the man page was
622 not present at all, then `missing' would create a replacement man page
623 containing an error message, and exit with a status of 2. This does not play
624 well with `make': the next run will see this particular man page as being up
625 to date, and will only error out on the next generated man page, if any;
626 repeat until all pages are done. This was not desirable.
628 These are the new semantics: if some man page is not present, and help2man
629 is not either, then `missing' will warn and generate the replacement page
630 containing the error message, but exit successfully. However, `make dist'
631 will ensure that no such bogus man pages are packaged into a tarball.
633 - Targets provided by automake behave better with `make -n', in that they
634 take care not to create files.
636 - `config.status Makefile... depfiles' works fine again in the presence of
637 disabled dependency tracking.
639 - The default no-op recursive rules for these targets also work with BSD make
640 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
642 - `make distcheck' works also when both a directory and some file below it
643 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
645 - Texinfo dvi, ps, pdf, and html output files are not removed upon
646 `make mostlyclean' any more; only the LaTeX by-products are.
648 - Renamed objects also work with the `subdir-objects' option and
649 source file languages which Automake does not know itself.
651 - `automake' now correctly complains about variable assignments which are
652 preceded by a comment, extend over multiple lines with backslash-escaped
653 newlines, and end in a comment sign. Previous versions would silently
654 and wrongly ignore such assignments completely.
656 * Bugs introduced by 1.10:
658 - Fix output of dummy dependency files in presence of post-processed
659 Makefile.in's again, but also cope with long lines.
661 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
662 that have been declared as programs in the same Makefile.
663 This is for consistency with the analogous change to TESTS in 1.10.
665 - Fix order of standard includes to again be `-I. -I$(srcdir)',
666 followed by directories containing config headers.
668 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
672 * Version requirements:
674 - Autoconf 2.60 or greater is required.
676 - Perl 5.6 or greater is required.
678 * Changes to aclocal:
680 - aclocal now also supports -Wmumble and -Wno-mumble options.
682 - `dirlist' entries (for the aclocal search path) may use shell
683 wildcards such as `*', `?', or `[...]'.
685 - aclocal supports an --install option that will cause system-wide
686 third-party macros to be installed in the local directory
687 specified with the first -I flag. This option also uses #serial
688 lines in M4 files to upgrade local macros.
690 The new aclocal options --dry-run and --diff help to review changes
691 before they are installed.
693 - aclocal now outputs an autoconf version check in aclocal.m4 in
694 projects using automake.
696 For a few years, automake and aclocal have been calling autoconf
697 (or its underlying engine autom4te) to accurately retrieve the
698 data they need from configure.ac and its siblings. Doing so can
699 only work if all autotools use the same version of autoconf. For
700 instance a Makefile.in generated by automake for one version of
701 autoconf may stop working if configure is regenerated with another
702 version of autoconf, and vice versa.
704 This new version check ensures that the whole build system has
705 been generated using the same autoconf version.
707 * Support for new Autoconf macros:
709 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
711 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
712 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
713 in different directories. However, only one instance of such a
714 library objects directory is supported.
716 * Change to Libtool support:
718 - Libtool generic flags (those that go before the --mode=MODE option)
719 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
721 * Yacc and Lex changes:
723 - The rebuild rules for distributed Yacc and Lex output will avoid
724 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
727 - ylwrap is now always used for lex and yacc source files,
728 regardless of whether there is more than one source per directory.
732 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
733 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
734 tracking, unlike non-preprocessed assembler (*.s).
736 - subdir-object mode works now with Assembler. Automake assumes
737 that the compiler understands `-c -o'.
739 - Preprocessed assembler (*.S) compilation now also honors
740 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
742 - Improved support for Objective C:
743 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
744 - A new section of the manual documents the support.
746 - New support for Unified Parallel C:
747 - AM_PROG_UPC looks for a UPC compiler.
748 - A new section of the manual documents the support.
750 - Per-target flags are now correctly handled in link rules.
752 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
753 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
754 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
755 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
757 The fix for compiler flags (i.e., using maude_CFLAGS instead of
758 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
759 is expected to work (and actually works during compilation).
761 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
762 "in addition to" breaks backward compatibility with older versions.
763 If your package used both variables, as in
765 AM_LDFLAGS = common flags
767 a_LDFLAGS = more flags
770 and assumed *_LDFLAGS would sum up, you should rewrite it as
772 AM_LDFLAGS = common flags
774 a_LDFLAGS = $(AM_LDFLAGS) more flags
777 This new behavior of *_LDFLAGS is more coherent with other
778 per-target variables, and the way *_LDFLAGS variables were
779 considered internally.
781 * New installation targets:
783 - New targets mandated by GNU Coding Standards:
788 By default they will only install Texinfo manuals.
789 You can customize them with *-local variants:
795 - The undocumented recursive target `uninstall-info' no longer exists.
796 (`uninstall' is in charge of removing all possible documentation
797 flavors, including optional formats such as dvi, ps, or info even
798 when `no-installinfo' is used.)
800 * Miscellaneous changes:
802 - Automake no longer complains if input files for AC_CONFIG_FILES
803 are specified using shell variables.
805 - clean, distribution, or rebuild rules are normally disabled for
806 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
807 AC_CONFIG_LINK specified using shell variables. However, if these
808 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
809 be able to output rules anyway.
810 (See the Automake documentation for AC_CONFIG_FILES.)
812 - $(EXEEXT) is automatically appended to filenames of TESTS
813 that have been declared as programs in the same Makefile.
814 This is mostly useful when some check_PROGRAMS are listed in TESTS.
816 - `-Wportability' has finally been turned on by default for `gnu' and
817 `gnits' strictness. This means, automake will complain about %-rules
818 or $(GNU Make functions) unless you switch to `foreign' strictness or
819 use `-Wno-portability'.
821 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
822 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
823 $(mkdir_p) variable is still defined (to the same value as
824 $(MKDIR_P)) but should be considered obsolete. If you are using
825 $(mkdir_p) in some of your rules, please plan to update them to
826 $(MKDIR_P) at some point.
828 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
829 They still work in this release, but may be withdrawn in a future one.
831 - Inline compilation rules for gcc3-style dependency tracking are
834 - Automake installs a "Hello World!" example package in $(docdir).
835 This example is used throughout the new "Autotools Introduction"
836 chapter of the manual.
838 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
842 * Makefile.in bloat reduction:
844 - Inference rules are used to compile sources in subdirectories when
845 the `subdir-objects' option is used and no per-target flags are
846 used. This should reduce the size of some projects a lot, because
847 Automake used to output an explicit rule for each such object in
850 - Automake no longer outputs three rules (.o, .obj, .lo) for each
851 object that must be built with explicit rules. It just outputs
852 the rules required to build the kind of object considered: either
853 the two .o and .obj rules for usual objects, or the .lo rule for
856 * Change to Libtool support:
858 - Libtool tags are used with libtool versions that support them.
859 (I.e., with Libtool 1.5 or greater.)
861 - Automake is now able to handle setups where a libtool library is
862 conditionally installed in different directories, as in
865 lib_LTLIBRARIES = liba.la
867 pkglib_LTLIBRARIES = liba.la
869 liba_la_SOURCES = ...
871 * Changes to aclocal:
873 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
874 really evaluated, before it decides to include them in aclocal.m4.
875 This solves nasty problems with conditional redefinitions of
876 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
877 *.m4 files to be included in any project using these macros.
878 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
879 most famous instance of this bug.)
881 - Do not complain about missing conditionally AC_REQUIREd macros
882 that are not actually used. In 1.8.x aclocal would correctly
883 determine which of these macros were really needed (and include
884 only these in the package); unfortunately it would also require
885 all of them to be present in order to run. This created
886 situations were aclocal would not work on a tarball distributing
887 all the macros it uses. For instance running aclocal on a project
888 containing only the subset of the Gettext macros in use by the
889 project did not work, because gettext conditionally requires other
892 * Portability improvements:
894 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
895 tar-pax. The new option filename-length-max=99 helps diagnosing
896 filenames that are too long for tar-v7. (PR/414)
898 - Variables aumented with `+=' are now automatically flattened (i.e.,
899 trailing backslashes removed) and then wrapped around 80 colummns
900 (adding trailing backslashes). In previous versions, a long series
906 would result in a single-line definition of VAR that could possibly
907 exceed the maximum line length of some make implementations.
909 Non-augmented variables are still output as they are defined in
914 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
915 Works the same as the old Fortran 77 implementation; just replace
916 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
917 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
919 - Support for conditional _LISP.
921 - Support for conditional -hook and -local rules (PR/428).
923 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
925 - Automake will not write any Makefile.ins after the first error it
926 encounters. The previous Makefile.ins (if any) will be left in
927 place. (Warnings will not prevent output, but remember they can
928 be turned into errors with -Werror.)
930 - The restriction that SUBDIRS must contain direct children is gone.
933 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
934 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
936 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
940 * Long-standing bugs:
942 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
943 so that `make distclean' and `make maintainer-clean' can work.
945 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
947 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
949 - Polish diagnostic when no input file is found.
951 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
955 * Long-standing bugs:
957 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
958 overridden by the user.
960 - Honor PATH_SEPARATOR in various places of the Automake package, for
963 - Adjust dependency tracking mode detection to ICC 8.0's new output.
966 - Fix install-sh so it can install the `mv' binary... using `mv'.
968 - Fix tru64 dependency tracking for libtool objects.
970 - Work around Exuberant Ctags when creating a TAGS files in a directory
971 without files to scan but with subdirectories to include.
973 * Bugs introduced by 1.8:
975 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
976 not defined in the same conditions as the _LDADD that uses it.
978 - Do not warn when JAVAROOT is overridden, this is legitimate.
980 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
984 * Long-standing bugs:
986 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
987 or any of the other *dir variables contain a space.
989 Please note that Automake does not and cannot support spaces in
990 filenames that are involved during the build. This change affects
991 only installation paths, so that `make install' does not bomb out
992 in packages configured with
993 ./configure --prefix '/c/Program Files'
995 - Fix the depfiles output so it works with GNU sed (<4.1) even when
996 POSIXLY_CORRECT is set.
998 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
999 since Autoconf 2.54, which defines LIBOBJS itself.
1001 - Fix a potential (but unlikely) race condition in parallel elisp
1002 builds. (Introduced in 1.7.3.)
1004 - Do not assume that users override _DEPENDENCIES in all conditions
1005 where Automake will try to define them.
1007 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1008 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1011 This fix also affects the $(mkdir_p) variable defined since
1012 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1013 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1015 - Secure temporary directory creation in `make distcheck'. (PR/413)
1017 - Do not generate two build rules for `parser.h' when the
1018 parser appears in two different conditionals.
1020 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1021 checking. Usually ./configure will not pick this shell; so this
1022 fix only helps cases where the shell is forced to /bin/sh.
1024 * Bugs introduced by 1.8:
1026 - In some situations (hand-written `m4_include's), aclocal would
1027 call the `File::Spec->rel2abs' method, which was only introduced
1028 in Perl 5.6. This new version reestablish support Perl 5.005.
1030 It is likely that the next major Automake releases will require at
1031 least Perl 5.6. Consider upgrading your development environment
1032 if you are still using the five-year-old Perl 5.005.
1034 - Automake would sometimes fail to define rules for targets listed
1035 in variables defined in multiple conditions. For instance on
1041 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1042 `b.$(OBJEXT): b.c' rule.
1044 * New sections in manual:
1046 - Third-Party Makefiles: how to interface third party Makefiles.
1047 - Upgrading: upgrading packages to newer Automake versions.
1048 - Multiple Outputs: handling tools that produce many outputs.
1050 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1054 * A (well known) portability bug slipped in the changes made to
1055 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1056 install anything on Tru64.
1058 * Fix install rules for conditionally built python files. (This never
1061 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1065 * Bugs introduced by 1.8:
1067 - Fix Config.pm import error with old Perl versions (at least
1068 5.005_03). One symptom is that aclocal could not find its macro
1071 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1072 created by `make install' are always world readable, even if the
1073 installer happens to have an overly restrictive umask (e.g. 077).
1074 This was a mistake and has been reverted. There are at least two
1075 reasons why we must not use `-m 0755':
1076 - it causes special bits like SGID to be ignored,
1077 - it may be too restrictive (some setups expect 775 directories).
1079 - Fix aclocal to honor definitions located in files which have been
1080 m4_included manually. aclocal 1.8 had been updated to check
1081 m4_included files for new requirements, but forgot that these
1082 m4_included files can also provide new definitions.
1084 Note that if you have such a setup, we recommend you get rid of
1085 it. In the past, there was a reason to m4_include files manually:
1086 aclocal used to duplicate entire M4 files into aclocal.m4, even
1087 files that were distributed. Some packages were therefore
1088 m4_including the distributed file directly, and playing some
1089 tricks to ensure aclocal would not copy that file to aclocal.m4,
1090 in order to limit the amount of duplication. Since aclocal 1.8.x
1091 will precisely output m4_includes for local M4 files, we recommend
1092 that you clean up your setup, removing all manual m4_includes and
1093 letting aclocal output them.
1095 - Output detailed menus in the Info version if the Automake manual,
1096 so that Emacs can locate the indexes.
1098 - configure.ac and configure were listed twice in DIST_COMMON (an
1099 internal variable where Automake lists configury files to
1100 distribute). This was harmless, but unaesthetic.
1102 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1103 This was an issue only in the Automake package itself, not in
1106 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1107 DEST:SRC. This was wrong, as some packages do
1108 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1111 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1112 argument. This caused two kinds of failures:
1113 - Rules installing data in a conditionally defined directory
1114 failed when that directory was undefined. In this case no
1115 argument was supplied.
1116 - `make installdirs' failed, because several directories were
1117 passed to $(mkdir_p). This was an issue only on platform
1118 were $(mkdir_p) is implemented with `install-sh -d'.
1119 $(mkdir_p) as been changed to accept 0 or more arguments, as
1122 * Long-standing bugs:
1124 - Fix an unexpected diagnostic occurring when users attempt
1125 to override some internal variables that Automake appends to.
1127 - aclocal now scans configure.ac for macro definitions (PR/319).
1129 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1130 distributes files which are outside itself (this usually occurs
1131 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1132 from a parent package), then `make distcheck' fails due to an
1133 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1134 (tests/subpkg2.test failure)
1136 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1137 In a VPATH-build configuration, `make install' would install
1138 nobase_ files to wrong locations.
1140 - Fix a Perl `uninitialized value' diagnostic occurring when
1141 automake complains that a Texinfo file does not have a
1142 @setfilename statement.
1144 - Erase config.status.lineno during `make distclean'. This file
1145 can be created by config.status. Automake already knew about
1146 configure.lineno, but forgot config.status.lineno.
1148 - Distribute all files, even those which are built and installed
1149 conditionally. This change affects files listed in conditionally
1150 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1151 as well as those listed in conditionally defined dist_*_DATA,
1152 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1154 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1155 doesn't conform to POSIX.
1157 - Normalize help strings for configure variables and options added
1162 - Check for python2.4 in AM_PATH_PYTHON.
1164 * Spurious failures in test suite:
1166 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1167 tests/ltconv.test: fix failures with CVS Libtool.
1168 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1169 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1170 fix failures with old Texinfo versions.
1172 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1178 - The NEWS file is more verbose.
1182 - Autoconf 2.58 or greater is required.
1186 - Default source file names in the absence of a _SOURCES declaration
1187 are made by removing any target extension before appending `.c', so
1188 to make the libtool module `foo.la' from `foo.c', you only need to
1191 lib_LTLIBRARIES = foo.la
1192 foo_la_LDFLAGS = -module
1194 For backward compatibility, foo_la.c will be used instead of
1195 foo.c if this file exists or is the explicit target of a rule.
1196 However -Wobsolete will warn about this deprecated naming.
1198 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1199 of being hard-coded in each $(AR) invocation, so they can be
1200 substituted from configure.ac. This has been requested by people
1201 dealing with non-POSIX ar implementations.
1203 - New warning option: -Woverride. This will warn about any user
1204 target or variable definitions which override Automake
1207 - Texinfo rules back up and restore info files when makeinfo fails.
1209 - Texinfo rules now support the `html' target.
1210 Running this requires Texinfo 4.0 or greater.
1212 `html' is a new recursive target, so if your package mixes
1213 hand-crafted `Makefile.in's with Automake-generated
1214 `Makefile.in's, you should adjust the former to support (or
1215 ignore) this target so that `make html' recurses successfully. If
1216 you had a custom `html' rule in your `Makefile.am', it's better to
1217 rename it as `html-local', otherwise your rule will override
1218 Automake's new rule (you can check that by running `automake
1219 -Woverride') and that will stop the recursion to subdirectories.
1221 Last but not least, this `html' rule is declared PHONY, even when
1222 overridden. Fortunately, it appears that few packages use a
1223 non-PHONY `html' rule.
1225 - Any file which is m4_included from configure.ac will appear as a
1226 configure and Makefile.in dependency, and will be automatically
1229 - The rules for rebuilding Makefiles and Makefile.ins will now
1230 rebuild all Makefiles and all Makefile.ins at once when one of
1231 configure's dependencies has changed. This is considerably faster
1232 than previous implementations, where config.status and automake
1233 were run separately in each directory (this still happens when you
1234 change a Makefile.am locally, without touching configure.ac or
1235 friends). Doing this also solves a longstanding issue: these
1236 rebuild rules failed to work when adding new directories to the
1237 tree, forcing you to run automake manually.
1239 - For similar reasons, the rules to rebuild configure,
1240 config.status, and aclocal.m4 are now defined in all directories.
1241 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1242 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1243 should better define them in all directories. This is easily done
1244 using an AC_SUBST (make sure you prefix these dependencies with
1245 $(top_srcdir) since this variable will appear at different
1246 levels of the build tree).
1248 - aclocal will now use `m4_include' instead of copying local m4
1249 files into aclocal.m4. (Local m4 files are those you ship with
1250 your project, other files will be copied as usual.)
1252 Because m4_included files are automatically distributed, it means
1253 for most projects there is no point in EXTRA_DISTing the list of
1254 m4 files which are used. (You can probably get rid of
1255 m4/Makefile.am if you had one.)
1257 - aclocal will avoid touching aclocal.m4 when possible, so that
1258 Autom4te's cache isn't needlessly invalidated. This behavior can
1259 be switched off with the new `--force' option.
1261 - aclocal now uses Autoconf's --trace to detect macros which are
1262 actually used and will no longer include unused macros simply
1263 because they where mentioned. This was often the case for macros
1264 called conditionally.
1266 - New options no-dist and no-dist-gzip.
1268 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1269 py-compile, and ylwrap, now all understand --version and --help.
1271 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1272 links as part of the distclean target and including source files in
1275 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1276 argument. The latter can be used to override the default behavior
1277 (which is to abort).
1279 - Automake will exit with $? = 63 on version mismatch. (So does
1280 Autoconf 2.58) missing knows this, and in this case it will
1281 emulate the tools as if they were absent. Because older versions
1282 of Automake and Autoconf did not use this exit code, this change
1283 will only be useful in projects generated with future versions of
1286 - When using AC_CONFIG_FILES with multiple input files, Automake
1287 generates the first ".in" input file for which a ".am" exists.
1288 (Former versions would try to use only the first input file.)
1290 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1291 idiom to disable byte-compilation of lisp_LISP files, it is
1292 recommended that you switch to using lisp_DATA. Note that
1293 this is not strictly equivalent: lisp_DATA will install elisp
1294 files even if emacs is not installed, while *_LISP do not
1295 install anything unless emacs is found.
1297 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1298 available. This selection is achieved through the Makefile
1299 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1300 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1301 `$(install_sh) -m 0755 -d'.
1305 - Because `mkdir -p' is available on most platforms, and we can use
1306 `install-sh -d' when it is not, the use of the mkinstalldirs
1307 script is being phased out. `automake --add-missing' no longer
1308 installs it, and if you remove mkinstalldirs from your package,
1309 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1311 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1312 gettextize and autopoint will install it when needed. Automake
1313 will continue to define the $(mkinstalldirs) and to distribute
1314 mkinstalldirs when this script is in the source tree.
1316 - AM_PROG_CC_STDC is now empty. The content of this macro was
1317 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1318 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1319 renaming should be safe, even if you have to support several,
1320 versions of Automake, because AC_PROG_CC defines this variable
1321 since Autoconf 2.54.)
1323 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1324 variable to override the aclocal.m4 dependencies computed
1325 (inaccurately) by older versions of Automake. Because Automake
1326 now tracks configure's m4 dependencies accurately (see m4_include
1327 above), the use of ACLOCAL_M4_SOURCES should be considered
1328 obsolete and will be flagged as such when running `automake
1333 - Defining programs conditionally using Automake conditionals no
1334 longer leads to a combinatorial explosion. The following
1335 construct used to be troublesome when used with dozens of
1350 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1352 - Due to implementation constraints, previous versions of Automake
1353 proscribed multiple conditional definitions of some variables
1363 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1364 This restriction has been lifted, and these variables now
1365 support multiple conditional definitions as do other variables.
1367 - Cleanup the definitions of $(distdir) and $(top_distdir).
1368 $(top_distdir) now points to the root of the distribution
1369 directory created during `make dist', as it did in Automake 1.4,
1370 not to the root of the build tree as it did in intervening
1371 versions. Furthermore these two variables are now only defined in
1372 the top level Makefile, and passed to sub-directories when running
1375 - The --no-force option now correctly checks the Makefile.in's
1376 dependencies before deciding not to update it.
1378 - Do not assume that make files are called Makefile in cleaning rules.
1380 - Update .info files in the source tree, not in the build tree. This
1381 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1382 used to update these files in the build tree (previous versions did
1383 it in the source tree too), and it caused several problems, varying
1384 from mere annoyance to portability issues.
1386 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1387 when --add-missing and --force-missing are used. For backward
1388 compatibility --add-missing will continue to install COPYING (in
1389 `gnu' strictness) when none of these three files exist, but this
1390 use is deprecated: you should better choose a license yourself and
1391 install it once for all in your source tree (and in your code
1394 - Fix ylwrap so that it does not overwrite header files that haven't
1395 changed, as the inline rule already does.
1397 - User-defined rules override automake-defined rules for the same
1398 targets, even when rules do not have commands. This is not new
1399 (and was documented), however some of the automake-generated
1400 rules have escaped this principle in former Automake versions.
1401 Rules for the following targets are affected by this fix:
1403 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1404 info, info-am, install-data-am, install-exec-am, install-info,
1405 install-info-am, install-man, installcheck-am, maintainer-clean,
1406 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1407 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1409 Practically it means that an attempt to supplement the dependencies
1410 of some target, as in
1412 clean: my-clean-rule
1414 will now *silently override* the automake definition of the
1415 rule for this target. Running `automake -Woverride' will diagnose
1416 all such overriding definitions.
1418 It should be noted that almost all these targets support a *-local
1419 variant that is meant to supplement the automake-defined rule
1420 (See node `Extending' in the manual). The above rule should
1423 clean-local: my-clean-rule
1425 These *-local targets have been documented since at least
1426 Automake 1.2, so you should not fear the change if you have
1427 to support multiple automake versions.
1431 - The Automake manual is now distributed under the terms of the GNU FDL.
1433 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1435 - core dumps are no longer removed by the cleaning rules. There are
1436 at least three reasons for this:
1437 1. These files should not be created by any build step,
1438 so their removal do not fit any of the cleaning rules.
1439 Actually, they may be precious to the developer.
1440 2. If such file is created during a build, then it's clearly a
1441 bug Automake should not hide. Not removing the file will
1442 cause `make distcheck' to complain about its presence.
1443 3. Operating systems have different naming conventions for
1444 core dump files. A core file on one system might be a
1445 completely legitimate data file on another system.
1447 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1448 defined by Automake. This means that any definition in the
1449 environment will be used, unless overridden in the Makefile.am or
1450 on the command line. The old behavior, where these variables were
1451 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1452 AC_ARG_VARing each variable from configure.ac.
1454 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1455 documented. (The is not a new feature, these variables have
1456 been there since at least Automake 1.4.)
1458 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1461 * Fix install-strip to work with nobase_ binaries.
1462 * Fix renaming of #line directives in ylwrap.
1463 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1465 Bugs fixed in 1.7.8:
1466 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1467 * Fix detection of Debian's install-info, broken since version 1.5.
1468 (Debian bug #213524).
1469 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1470 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1472 Bugs fixed in 1.7.7:
1473 * The implementation of automake's --no-force option is unreliable,
1474 so this option is ignored in this version. A real fix will appear in
1475 Automake 1.8. (Debian Bug #206299)
1476 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1477 argument is given. (PR/399)
1478 * Do not warn about leading `_' in variable names, even with -Wportability.
1479 * Support user redefinitions of TEXINFO_TEX.
1480 * depcomp: support AIX Compiler version 6.
1481 * Fix missing rebuilds during `make dist' with BSD make.
1482 (Could produce tarballs containing out-of-date files.)
1483 * Resurrect multilib support.
1484 * Noteworthy manual updates:
1485 - Extending aclocal: how to write m4 macros that won't trigger warnings
1487 - A Shared Library: Rewrite and split into subsections.
1489 Bugs fixed in 1.7.6:
1490 * Fix depcomp's icc mode for ICC 7.1.
1491 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1492 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1493 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1494 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1495 * Remove Latin-1 characters from elisp-comp.
1496 * Update the manual's @dircategory to match the Free Software Directory.
1498 Bugs fixed in 1.7.5:
1499 * Update install-sh's license to remove an advertising clause.
1500 (Debian bug #191717)
1501 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1502 that caused invalid Makefile.ins to be generated.
1503 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1504 * New FAQ entry: renamed objects.
1506 Bugs fixed in 1.7.4:
1507 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1508 the Emacs implementation)
1509 * Fix output of aclocal.m4 dependencies in subdirectories.
1510 * Use `mv -f' instead of `mv' in fastdep rules.
1511 * Upgrade mdate-sh to work on OS/2.
1512 * Don't byte-compile elisp files when ELCFILES is set empty.

1519 * `make install' will build `BUILT_SOURCES' first.
1520 * Minor documentation fixes.
1522 Bugs fixed in 1.7.3:
1523 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1524 * Query distutils for `pythondir' and `pythonexecdir', instead of
1525 using an hardcoded path. This should allow builds on 64-bit
1526 distributions that usually use lib64/ instead of lib/.
1527 * AM_PATH_PYTHON will also search for python2.3.
1528 * elisp files are now built all at once instead of one by one. Besides
1529 incurring a speed-up, this is required to support interdependent elisp files.
1530 * Support for DJGPP:
1531 - `make distcheck' will now work in `_inst/' and `_build' instead
1532 of `=inst/' and `=build/'
1533 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1534 - install/uninstall `*.i[0-9][0-9]'-style info files
1535 - more changes that affect only the Automake package (not its output)
1536 * Fix some incompatibilities with upcoming perl-5.10.
1537 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1538 PACKAGE and VERSION.
1540 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1541 is troublesome with gcc and Solaris compilers. (PR/385)
1542 - makedepend mode: work with Libtool. (PR/385 too)
1544 * better support for unusual gettext setups, such as multiple po/ directories
1546 - Flag missing po/ and intl/ directories as warnings, not errors.
1547 - Disable these warnings if po/ does not exist.
1548 * Noteworthy manual updates:
1550 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1552 - Document `AM_YFLAGS = -d'. (PR/382)
1554 Bugs fixed in 1.7.2:
1555 * Fix installation and uninstallation of Info files built in subdirectories.
1556 * Do not run `./configure --with-included-gettext' during `make distcheck'
1557 if AM_GNU_GETTEXT([external]) is used.
1558 * Correctly uninstall renamed man pages.
1559 * Do not strip escaped newline in variables defined in one condition
1560 and augmented in another condition.
1561 * Fix ansi2knr rules for LIBOBJS sources.
1562 * Clean all known Texinfo index files, not only those which appear to
1563 be used, because we cannot know which indexes are used in included files.
1564 (PR/375, Debian Bug #168671)
1565 * Honor only the first @setfilename seen in a Texinfo file.
1566 * Treat "required file X not found" diagnostics as errors (exit status 1).
1567 * Don't complain that a required file is not found when it is a Makefile
1569 * Don't use single suffix inference rules when building `.info'-less
1570 Info files, for the sake of Solaris make.
1571 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1572 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1573 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1574 * Fix building of deansified files from subdirectories. (PR/370)
1575 * Add missing `fi' in the .c->.obj rules.
1576 * Improve install-sh to work even when names contain spaces or certain
1577 (but not all) shell metachars.
1578 * Fix the following spurious failures in the test suite:
1579 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1580 * Noteworthy manual updates:
1581 - Augment the section about BUILT_SOURCES.
1582 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1584 Bugs fixed in 1.7.1:
1585 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1587 * Aclocal should now recognize macro names containing parentheses, e.g.
1588 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1589 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1591 * Install Python files even if they were built. (PR/369)
1592 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1593 version might not be defined in the latter. (PR/358)
1594 * Reorder arguments passed to a couple of commands, so things works
1595 when POSIXLY_CORRECT=1.
1596 * Fix a regex that can cause Perl to segfault on large input.
1598 * Fix distribution of packages that have some sources defined conditionally,
1599 as in the `Conditional compilation using Automake conditionals' example
1601 * Fix spurious test suite failures on IRIX.
1602 * Don't report a required variable as undefined if it has been
1603 defined conditionally for the "right" conditions.
1604 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1605 `make distcheck' fails.
1606 * Fix distribution of included Makefile fragment, so we don't create
1607 spurious directories in the distribution. (PR/366)
1608 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1611 * Autoconf 2.54 is required.
1612 * `aclocal' and `automake' will no longer warn about obsolete
1613 configure macros. This is done by `autoconf -Wobsolete'.
1614 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1615 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1616 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1617 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1618 `configure.ac' for you.
1619 * Support for per-program and per-library `_CPPFLAGS'.
1620 * New `ctags' target (builds CTAGS files).
1621 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1622 (see `automake --help' or the manual for a list of them).
1623 * Honor the WARNINGS environment variable.
1624 * Omit the call to depcomp when using gcc3: call the compiler directly.
1625 * A new option, std-options, tests that programs support --help and --version
1626 when `make installcheck' is run. This is enabled by --gnits.
1627 * Texinfo rules now support the `ps' and `pdf' targets.
1628 * Info files are now created in the build directory, not the source directory.
1629 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1631 * `make distcheck' will enforce DESTDIR support by attempting
1633 * `+=' can be used in conditionals, even if the augmented variable
1634 was defined for another condition.
1635 * Makefile fragments (inserted with `include') are always distributed.
1636 * Use Autoconf's --trace interface to inspect configure.ac and get
1637 a more accurate view of it.
1638 * Add support for extending aclocal's default macro search path
1639 using a `dirlist' file within the aclocal directory.
1640 * automake --output-dir is deprecated.
1641 * The part of the distcheck target that checks whether uninstall actually
1642 removes all installed files has been moved in a separate target,
1643 distuninstallcheck, so it can be overridden easily.
1647 * Support for AM_INIT_GETTEXT([external])
1648 * Bug fixes, including:
1649 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1650 - nobase_ programs and scripts honor --program-transform correctly.
1651 - Erase configure.lineno during `make distclean'.
1652 - Erase YACC and LEX outputs during `make maintainer-clean'.
1655 * Many bug fixes, including:
1656 - Requiring the current version works.
1657 - Fix "$@" portability issues (for Zsh).
1658 - Fix output of dummy dependency files in presence of post-processed
1660 - Don't compute dependencies in background to avoid races with libtool.
1661 - Fix handling of _OBJECTS variables for targets sharing source variables.
1662 - Check dependency mode for Java when AM_PROG_GCJ is used.
1665 * automake --output-dir is deprecated
1666 * Many bug fixes, including:
1667 - Don't choke on AM_LDFLAGS definitions.
1668 - Clean libtool objects from subdirectories.
1669 - Allow configure variables with reserved suffix and unknown prefix
1670 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1671 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1674 * Autoconf 2.52 is required.
1675 * automake no longer run libtoolize.
1676 This is the job of autoreconf (from GNU Autoconf).
1677 * `dist' generates all the archive flavors, as did `dist-all'.
1678 * `dist-gzip' generates the Gzip tar file only.
1679 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1680 explosion. Makefile.in's keep a reasonable size.
1681 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1682 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1684 * `#line' of Lex and Yacc files are properly set.
1685 * EXTRA_DIST can contain generated directories.
1686 * Support for dot-less extensions in suffix rules.
1687 * The part of the distcheck target that checks whether distclean actually
1688 cleans all built files has been moved in a separate target, distcleancheck,
1689 so it can be overridden easily.
1690 * `make distcheck' will pass additional options defined in
1691 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1692 * Fixed CDPATH portability problems, in particular for MacOS X.
1693 * Fixed handling of nobase_ targets.
1694 * Fixed support of implicit rules leading to .lo objects.
1695 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1696 * Added uninstall-hook target
1697 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1698 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1699 (Note that "pkgname" is not "tarname", see the manual for details.)
1700 It is also possible to pass a list of global Automake options as
1701 first argument to this new form of AM_INIT_AUTOMAKE.
1702 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1703 to be a real assembler.
1704 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1705 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1706 * aclocal and automake are also installed with the version number
1707 appended, and some of the install directory names have changed.
1708 This lets you have multiple versions installed simultaneously.
1709 * Support for parsers and lexers in subdirectories.
1712 * Support for `configure.ac'.
1713 * Support for `else COND', `endif COND' and negated conditions `!COND'.
1714 * `make dist-all' is much faster.
1715 * Allows '@' AC_SUBSTs in macro names.
1716 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
1717 * User-side dependency tracking. Developers no longer need GNU make
1719 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
1720 * Most files are correctly handled if they appear in subdirs
1721 For instance, a _DATA file can appear in a subdir
1722 * GNU tar is no longer required for `make dist'
1723 * Added support for `dist_' and `nodist_' prefixes
1724 * Added support for `nobase_' prefix

1726 * Support for per-executable and per-library compilation flags
1730 * Added support for the Fortran 77 programming language.
1731 * Re-indexed the Automake Texinfo manual.
1732 * Added `AM_FOOFLAGS' variable for each compiler invocation;
1733 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
1734 * Support for latest autoconf, including support for objext
1735 * Can now put `.' in SUBDIRS to control build order
1736 * `include' command and `+=' support for macro assignment
1737 * Dependency tracking no long susceptible to deleted header file problem
1738 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
1743 * Better Cygwin32 support
1744 * Support for suffix rules with _SOURCES variables
1745 * New options `readme-alpha' and `check-news'; Gnits mode sets these
1746 * @LEXLIB@ no longer required when lex source seen
1747 Lex support in `missing', and new lex macro. Update your missing script.
1748 * Built-in support for assembly
1749 * aclocal gives error if `AM_' macro not found

1760 * Added no-installinfo option
1761 * Added Emacs Lisp support
1762 * Added --no-force option
1763 * Included `aclocal' program
1764 * Automake will now generate rules to regenerate aclocal.m4, if appropriate
1765 * Now uses `AM_' macro names everywhere
1766 * ansi2knr option can have directory prefix (eg `../lib/ansi2knr')
1767 ansi2knr now works correctly on K&R sources
1768 * Better C++, yacc, lex support
1769 * Will compute _DEPENDENCIES variables automatically if not supplied
1770 * Will interpolate $(...) and ${...} when examining contents of a variable
1771 * .deps files now in build directory, not source directory; dependency
1772 handling generally rewritten
1773 * DATA, MANS and BUILT_SOURCES no longer included in distribution
1774 * can now put config.h into a subdir
1775 * Added dist-all target
1776 * Support for install-info program (see texinfo 3.9)
1777 * Support for "yacc -d"
1778 * configure substitutions are automatically discovered and included
1779 in generated Makefile.in
1780 * Special --cygnus mode
