5 - automake now generates silenced rules for texinfo outputs.
7 - The deprecated options `--output-dir', `--Werror' and `--Wno-error'
10 - The obsolete AM_WITH_REGEX macro has been removed.
14 - The `--acdir' option is deprecated. Now you should use the new options
15 `--automake-acdir' and `--system-acdir' instead.
17 - The `ACLOCAL_PATH' environment variable is now interpreted as a
18 colon-separated list of additional directories to search after the
19 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
20 and before the system acdir (by default ${prefix}/share/aclocal).
22 - The exact order in which the directories in the aclocal macro
23 search path are looked up is probably going to be changed in the
24 next Automake release (1.12).
28 - New `cscope' target to build a cscope database for the source tree.
30 * Changes to Automake-generated testsuite harnesses:
32 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
33 and unexpected or internal error, or a failure to set up the test case
34 scenario) have their outcome reported as an 'ERROR' now. Previous
35 versions of automake reported such an outcome as a 'FAIL' (the only
36 difference with normal failures being that hard errors were counted
37 as failures even when the test originating them was listed in
40 - The testsuite summary displayed by the parallel-test harness has a
41 completely new format, that always list the numbers of passed, failed,
42 xfailed, xpassed, skipped and errored tests, even when these numbers
43 are zero (but using smart coloring when the color-tests option is in
46 - The default testsuite driver offered by the 'parallel-tests' option is
47 now implemented (partly at least) with the help of automake-provided
48 auxiliary scripts (e.g., `test-driver'), instead of relying entirely
49 on code in the generated Makefile.in.
50 This has two noteworthy implications. The first one is that projects
51 using the `parallel-tests' option should now either run automake with
52 the `--add-missing' option, or manually copy the `test-driver' script
53 into their tree. The second, and more important, implication is that
54 now, when the `parallel-tests' option is in use, TESTS_ENVIRONMENT can
55 not be used anymore to define a test runner, and the command specified
56 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
57 program or script. For example, this is still a valid usage (albeit
61 if test -n '$(STRICT_TESTS)'; then \
66 LOG_COMPILER = $(SHELL) $$maybe_errexit
68 while this is not anymore:
71 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
76 run_with_perl_or_shell () \
78 if grep -q '^#!.*perl' $$1; then
84 LOG_COMPILER = run_with_per_or_shell
86 - The package authors can now use customary testsuite drivers within
87 the framework provided by the 'parallel-tests' testsuite harness.
88 Consistently with the existing syntax, this can be done by defining
89 special makefile variables `LOG_DRIVER' and `<ext>_LOG_DRIVER'.
91 - A new developer-reserved variable `AM_TESTS_FD_REDIRECT' can be used
92 to redirect/define file descriptors used by the test scripts.
94 - The parallel-tests harness generates now, in addition the `.log' files
95 holding the output produced by the test scripts, a new set of `.trs'
96 files, holding "metadata" derived by the execution of the test scripts;
97 among such metadata are the outcomes of the test cases run by a script.
99 - Initial and still experimental support for the TAP test protocol is
102 * Changes related to distribution tarballs:
104 - The `dist' and `dist-all' targets now can run compressors in parallel.
106 - Automake is now distributed as a gzip-compressed and an xz-compressed
107 tarball. Previously, bzip2 was used instead of xz.
109 - The last relics of Python 1.5 support have been removed from the
110 AM_PATH_PYTHON macro.
112 - The `lzma' compression scheme and associated automake option `dist-lzma'
113 is obsoleted by `xz' and `dist-xz' due to upstream changes.
115 - "make dist" can now create lzip-compressed tarballs.
117 - You may adjust the compression options used in dist-xz and dist-bzip2.
118 The default is now merely -e for xz, but still -9 for bzip; you may
119 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
120 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
122 - Some auxiliary files that are automatically distributed by Automake
123 (e.g., `install-sh', or the `depcomp' script for packages compiling
124 C sources) might now be listed in the DIST_COMMON variable in many
125 Makefile.in files, rather than in the top-level one.
127 * Miscellaneous changes:
129 - Messages of types warning or error from `automake' and `aclocal' are now
130 prefixed with the respective type, and presence of -Werror is noted.
132 - The `compile' script now converts some options for MSVC for a better
133 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
135 - Automake's early configure-time sanity check now tries to avoid sleeping
136 for a second, which slowed down cached configure runs noticeably. In that
137 case, it will check back at the end of the configure script to ensure that
138 at least one second has passed, to avoid time stamp issues with makefile
139 rules rerunning autotools programs.
141 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES and
142 adds them to the normal list of dependencies, but without overwriting the
143 foo_DEPENDENCIES variable, which is normally computed by automake.
145 - C source and header files derived from non-distributed Yacc sources are
146 now removed by "make clean", not only by "make maintainer-clean".
148 - The `compile' script now converts some options for MSVC for a better
149 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
151 - The py-compile script now accepts empty arguments passed to the options
152 `--destdir' and `--basedir', and complains about unrecognized options.
153 Moreover, a non-option argument or a special `--' argument terminates
156 - A developer that needs to pass specific flags to configure at "make
157 distcheck" time can now, and indeed is advised to, do so by defining
158 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
159 instead of the old DISTCHECK_CONFIGURE_FLAGS.
160 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
161 user; still, the old Makefile.am files that used to define it will
162 still continue to work as before.
164 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
165 'ar-lib' auxiliary script if the found archiver is Microsoft lib. This
166 new macro is required for LIBRARIES and LTLIBRARIES when automake is
167 run with -Wextra-portability (or -Wall) and -Werror.
169 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
170 file generated by automake-provided rules by defining the special make
171 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
173 - The `install-info' rule can now be instructed not to create/update
174 the `${infodir}/dir' file, by exporting the new environment variable
175 `AM_UPDATE_INFO_DIR' to the value "no".
177 - Support for automatic de-ANSI-fication has been removed.
181 - Lots of minor bugfixes.
183 * Bugs introduced by 1.11:
185 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
186 trailing white space in the test list (`TESTS = foo $(EMPTY)'), and
187 does not report spurious successes when used with concurrent FreeBSD
188 make (e.g., "make check -j3").
190 - When the parallel-tests driver is in use, automake now explicitly
191 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
192 instead of issuing confusing and apparently unrelated error messages
193 (e.g., "non-POSIX variable name", "bad characters in variable name",
194 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
195 silently producing broken `Makefile.in' files.
197 - The `silent-rules' option now truly silences all compile rules, even
198 when dependency tracking is disabled. Also, when `silent-rules' is
199 not used, `make' output no longer contains spurious backslash-only
200 lines, thus once again matching what Automake did before 1.11.
202 - The AM_COND_IF macro also works if the shell expression for the conditional
203 is no longer valid for the condition.
205 * Long-standing bugs:
207 - Automake's own build system finally have a real "installcheck" target.
209 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
210 now automatically distributed also if the directory of the auxiliary
211 files coincides with the top-level directory.
213 - The "deleted header file problem" for *.am files is avoided by stub
214 rules. This allows `make' to trigger a rerun of `automake' also if
215 some previously needed `.am' file has been removed.
217 - "make distcheck" now correctly complains also when "make uninstall"
218 leaves one and only one file installed in $(prefix).
220 - A "make uninstall" issued before a "make install", or after a mere
221 "make install-data" or a mere "make install-exec" does not spuriously
224 - Automake now warns about more primary/directory invalid combinations,
225 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
227 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
228 even if the `--prefix' argument pointed outside of a system directory.
229 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
230 `get_python_lib' function if it points outside the configured prefix,
231 unless the `--prefix' argument was either `/usr' or below `/System'.
233 - The testsuite does not try to change the mode of `ltmain.sh' files from
234 a Libtool installation (symlinked to test directories) any more.
236 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
237 tools are preferred in a cross-compile setup.
239 - The distribution is tarred up with mode 755 now by the `dist*' targets.
240 This fixes a race condition where untrusted users could modify files
241 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
242 build directory was world-searchable. This is CVE-2009-4029.
244 - Several scripts and the parallel-tests testsuite driver now exit with
245 the right exit status upon receiving a signal.
247 - A per-Makefile.am setting of -Werror does not erroneously carry over
248 to the handling of other Makefile.am files.
250 - The order of Yacc and Lex flags is now consistent with that of other
251 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
252 $(LFLAGS), so that the user variables override the developer variables.
254 - Rules generated by Automake now try harder not to change any files when
255 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
256 Yacc source files and the rule to update config.h.
258 - The code for automatic dependency tracking works around a Solaris
259 make bug triggered by sources containing repeated slashes when the
260 `subdir-objects' option was used.
262 - Automake now detects the presence of the `-d' flag in the various
263 `*YFLAGS' variables even when their definitions involve indirections
264 through other variables, such as in:
266 AM_YFLAGS = $(foo_opts)
268 - Automake now complains if a `*YFLAGS' variable has any conditional
269 content, not only a conditional definition.
271 - Explicit enabling and/or disabling of Automake warning categories
272 through the `-W...' options now always takes precedence over the
273 implicit warning level implied by Automake strictness (foreign, gnu
274 or gnits), regardless of the order in which such strictness and
275 warning flags appear. For example, a setting like:
276 AUTOMAKE_OPTIONS = -Wall --foreign
277 will cause the warnings in category `portability' to be enabled, even
278 if those warnings are by default disabled in `foreign' strictness.
280 - The parallel-tests driver no longer produces erroneous results with
281 Tru64/OSF 5.1 sh upon unreadable log files.
283 - The makedepend and hp depmodes now work better with VPATH builds.
285 - Java sources specified with check_JAVA are no longer compiled for
286 "make all", but only for "make check".
288 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
289 and error out if `javadir' is undefined, instead of silently producing
290 a broken Makefile.in.
292 - aclocal and automake now honour the configure-time definitions of
293 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
295 - The `install-info' recipe no longer tries to guess whether the
296 `install-info' program is from Debian or from GNU, and adaptively
297 change its behaviour; this has proven to be frail and easy to
302 * Version requirements:
304 - Autoconf 2.62 or greater is required.
306 * Changes to aclocal:
308 - The autoconf version check implemented by aclocal in aclocal.m4
309 (and new in Automake 1.10) is degraded to a warning. This helps
310 in the common case where the Autoconf versions used are compatible.
312 * Changes to automake:
314 - The automake program can run multiple threads for creating most
315 Makefile.in files concurrently, if at least Perl 5.7.2 is available
316 with interpreter-based threads enabled. Set the environment variable
317 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
318 enable this experimental feature.
320 * Changes to Libtool support:
322 - Libtool generic flags are now passed to the install and uninstall
325 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
326 config.lt is removed correctly now.
330 - subdir-object mode works now with Fortran (F77, FC, preprocessed
331 Fortran, and Ratfor).
333 - For files with extension .f90, .f95, .f03, or .f08, the flag
334 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
336 - Files with extension .sx are also treated as preprocessed assembler.
338 - The default source file extension (.c) can be overridden with
339 AM_DEFAULT_SOURCE_EXT now.
341 - Python 3.0 is supported now, Python releases prior to 2.0 are no
344 - AM_PATH_PYTHON honors python's idea about the site directory.
346 - There is initial support for the Vala programming language, when using
349 * Miscellaneous changes:
351 - Automake development is done in a git repository on Savannah now, see
353 http://git.sv.gnu.org/gitweb/?p=automake.git
355 A read-only CVS mirror is provided at
357 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
358 checkout -d automake HEAD
360 - "make dist" can now create xz-compressed tarballs,
361 as well as (deprecated?) lzma-compressed tarballs.
363 - `automake --add-missing' will by default install the GPLv3 file as
364 COPYING if it is missing. It will also warn that the license file
365 should be added to source control. Note that Automake will never
366 overwrite an existing COPYING file, even when the `--force-missing'
369 - The manual is now distributed under the terms of the GNU FDL 1.3.
371 - Automake ships and installs man pages for automake and aclocal now.
373 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
375 - install-sh supports -C, which does not update the installed file
376 (and its time stamps) if the contents did not change.
378 - The `gnupload' script has been revamped.
380 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
382 - The targets `install' and `uninstall' are more efficient now, in that
383 for example multiple files from one Automake variable such as
384 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
385 invocation if they do not have to be renamed.
387 Both install and uninstall may sometimes enter (`cd' into) the target
388 installation directory now, when no build-local scripts are used.
390 Both install and uninstall do not fail anymore but do nothing if an
391 installation directory variable like `bindir' is set to the empty string.
393 For built-in rules, `make install' now fails reliably if installation
394 of a file failed. Conversely, `make uninstall' even succeeds when
395 issued multiple times.
397 These changes may need some adjustments from users: For example,
398 some `install' programs refuse to install multiple copies of the
399 same file in one invocation, so you may need to remove duplicate
400 entries from file lists.
402 Also, within one set of files, say, nobase_data_DATA, the order of
403 installation may be changed, or even unstable among different hosts,
404 due to the use of associative arrays in awk. The increased use of
405 awk matches a similar move in Autoconf to provide for better scaling.
407 Further, most undocumented per-rule install command variables such as
408 binSCRIPT_INSTALL have been removed because they are not needed any
409 more. Packages which use them should be using the appropriate one of
410 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
411 counterpart, depending on the type of files and the need for automatic
412 target directory creation.
414 - The "deleted header file problem" for *.m4 files is avoided by
415 stub rules. This allows `make' to trigger a rerun of `aclocal'
416 also if some previously needed macro file has been removed.
418 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
419 an otherwise up to date tree.
421 - The `color-tests' option causes colored test result output on terminals.
423 - The `parallel-tests' option enables a new test driver that allows for
424 parallel test execution, inter-test dependencies, lazy test execution
425 for unit-testing, re-testing only failed tests, and formatted result output
426 as RST (reStructuredText) and HTML. Enabling this option may require some
427 changes to your test suite setup; see the manual for details.
429 - The `silent-rules' option enables Linux kernel-style silent build output.
430 This option requires the widely supported but non-POSIX `make' feature
431 of recursive variable expansion, so do not use it if your package needs
432 to build with `make' implementations that do not support it.
434 To enable less verbose build output, the developer has to use the Automake
435 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
436 macro. The user may then set the default verbosity by passing the
437 `--enable-silent-rules' option to `configure'. At `make' run time, this
438 default may be overridden using `make V=0' for less verbose, and `make V=1'
439 for backward-compatible verbose output.
441 - New prefix `notrans_' for manpages which should not be transformed
442 by --program-transform.
444 - New macro AM_COND_IF for conditional evaluation and conditional
447 - For AC_CONFIG_LINKS, if source and destination are equal, do not
448 remove the file in a non-VPATH build. Such setups work with Autoconf
451 - AM_MAINTAINER_MODE now allows for an optional argument specifying
454 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
455 useful especially for multi-line values.
457 - Automake's early configure-time sanity check now diagnoses an
458 unsafe absolute source directory name and makes configure fail.
460 - The Automake macros and rules cope better with whitespace in the
461 current directory name, as long as the relative path to `configure'
462 does not contain whitespace. To this end, the values of `$(MISSING)'
463 and `$(install_sh)' may contain suitable quoting, and their expansion
464 might need `eval'uation if used outside of a makefile. These
465 undocumented variables may be used in several documented macros such
466 as $(AUTOCONF) or $(MAKEINFO).
470 * Long-standing bugs:
472 - Fix aix dependency tracking for libtool objects.
474 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
475 unnecessary use of the `compile' script.
477 - For nobase_*_LTLIBRARIES with nonempty directory components, the
478 correct `-rpath' argument is used now.
480 - `config.status --file=Makefile depfiles' now also works with the
481 extra quoting used internally by Autoconf 2.62 and newer
482 (it used to work only without the `--file=' bit).
484 - The `missing' script works better with versioned tool names.
486 - Semantics for `missing help2man' have been revamped:
488 Previously, if `help2man' was not present, `missing help2man' would have
489 the following semantics: if some man page was out of date but present, then
490 a warning would be printed, but the exit status was 0. If the man page was
491 not present at all, then `missing' would create a replacement man page
492 containing an error message, and exit with a status of 2. This does not play
493 well with `make': the next run will see this particular man page as being up
494 to date, and will only error out on the next generated man page, if any;
495 repeat until all pages are done. This was not desirable.
497 These are the new semantics: if some man page is not present, and help2man
498 is not either, then `missing' will warn and generate the replacement page
499 containing the error message, but exit successfully. However, `make dist'
500 will ensure that no such bogus man pages are packaged into a tarball.
502 - Targets provided by automake behave better with `make -n', in that they
503 take care not to create files.
505 - `config.status Makefile... depfiles' works fine again in the presence of
506 disabled dependency tracking.
508 - The default no-op recursive rules for these targets also work with BSD make
509 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
511 - `make distcheck' works also when both a directory and some file below it
512 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
514 - Texinfo dvi, ps, pdf, and html output files are not removed upon
515 `make mostlyclean' any more; only the LaTeX by-products are.
517 - Renamed objects also work with the `subdir-objects' option and
518 source file languages which Automake does not know itself.
520 - `automake' now correctly complains about variable assignments which are
521 preceded by a comment, extend over multiple lines with backslash-escaped
522 newlines, and end in a comment sign. Previous versions would silently
523 and wrongly ignore such assignments completely.
525 * Bugs introduced by 1.10:
527 - Fix output of dummy dependency files in presence of post-processed
528 Makefile.in's again, but also cope with long lines.
530 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
531 that have been declared as programs in the same Makefile.
532 This is for consistency with the analogous change to TESTS in 1.10.
534 - Fix order of standard includes to again be `-I. -I$(srcdir)',
535 followed by directories containing config headers.
539 * Version requirements:
541 - Autoconf 2.60 or greater is required.
543 - Perl 5.6 or greater is required.
545 * Changes to aclocal:
547 - aclocal now also supports -Wmumble and -Wno-mumble options.
549 - `dirlist' entries (for the aclocal search path) may use shell
550 wildcards such as `*', `?', or `[...]'.
552 - aclocal supports an --install option that will cause system-wide
553 third-party macros to be installed in the local directory
554 specified with the first -I flag. This option also uses #serial
555 lines in M4 files to upgrade local macros.
557 The new aclocal options --dry-run and --diff help to review changes
558 before they are installed.
560 - aclocal now outputs an autoconf version check in aclocal.m4 in
561 projects using automake.
563 For a few years, automake and aclocal have been calling autoconf
564 (or its underlying engine autom4te) to accurately retrieve the
565 data they need from configure.ac and its siblings. Doing so can
566 only work if all autotools use the same version of autoconf. For
567 instance a Makefile.in generated by automake for one version of
568 autoconf may stop working if configure is regenerated with another
569 version of autoconf, and vice versa.
571 This new version check ensures that the whole build system has
572 been generated using the same autoconf version.
574 * Support for new Autoconf macros:
576 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
578 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
579 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
580 in different directories. However, only one instance of such a
581 library objects directory is supported.
583 * Change to Libtool support:
585 - Libtool generic flags (those that go before the --mode=MODE option)
586 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
588 * Yacc and Lex changes:
590 - The rebuild rules for distributed Yacc and Lex output will avoid
591 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
594 - ylwrap is now always used for lex and yacc source files,
595 regardless of whether there is more than one source per directory.
599 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
600 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
601 tracking, unlike non-preprocessed assembler (*.s).
603 - subdir-object mode works now with Assembler. Automake assumes
604 that the compiler understands `-c -o'.
606 - Preprocessed assembler (*.S) compilation now also honors
607 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
609 - Improved support for Objective C:
610 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
611 - A new section of the manual documents the support.
613 - New support for Unified Parallel C:
614 - AM_PROG_UPC looks for a UPC compiler.
615 - A new section of the manual documents the support.
617 - Per-target flags are now correctly handled in link rules.
619 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
620 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
621 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
622 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
624 The fix for compiler flags (i.e., using maude_CFLAGS instead of
625 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
626 is expected to work (and actually works during compilation).
628 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
629 "in addition to" breaks backward compatibility with older versions.
630 If your package used both variables, as in
632 AM_LDFLAGS = common flags
634 a_LDFLAGS = more flags
637 and assumed *_LDFLAGS would sum up, you should rewrite it as
639 AM_LDFLAGS = common flags
641 a_LDFLAGS = $(AM_LDFLAGS) more flags
644 This new behavior of *_LDFLAGS is more coherent with other
645 per-target variables, and the way *_LDFLAGS variables were
646 considered internally.
648 * New installation targets:
650 - New targets mandated by GNU Coding Standards:
655 By default they will only install Texinfo manuals.
656 You can customize them with *-local variants:
662 - The undocumented recursive target `uninstall-info' no longer exists.
663 (`uninstall' is in charge of removing all possible documentation
664 flavors, including optional formats such as dvi, ps, or info even
665 when `no-installinfo' is used.)
667 * Miscellaneous changes:
669 - Automake no longer complains if input files for AC_CONFIG_FILES
670 are specified using shell variables.
672 - clean, distribution, or rebuild rules are normally disabled for
673 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
674 AC_CONFIG_LINK specified using shell variables. However, if these
675 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
676 be able to output rules anyway.
677 (See the Automake documentation for AC_CONFIG_FILES.)
679 - $(EXEEXT) is automatically appended to filenames of TESTS
680 that have been declared as programs in the same Makefile.
681 This is mostly useful when some check_PROGRAMS are listed in TESTS.
683 - `-Wportability' has finally been turned on by default for `gnu' and
684 `gnits' strictness. This means, automake will complain about %-rules
685 or $(GNU Make functions) unless you switch to `foreign' strictness or
686 use `-Wno-portability'.
688 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
689 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
690 $(mkdir_p) variable is still defined (to the same value as
691 $(MKDIR_P)) but should be considered obsolete. If you are using
692 $(mkdir_p) in some of your rules, please plan to update them to
693 $(MKDIR_P) at some point.
695 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
696 They still work in this release, but may be withdrawn in a future one.
698 - Inline compilation rules for gcc3-style dependency tracking are
701 - Automake installs a "Hello World!" example package in $(docdir).
702 This example is used throughout the new "Autotools Introduction"
703 chapter of the manual.
707 * Makefile.in bloat reduction:
709 - Inference rules are used to compile sources in subdirectories when
710 the `subdir-objects' option is used and no per-target flags are
711 used. This should reduce the size of some projects a lot, because
712 Automake used to output an explicit rule for each such object in
715 - Automake no longer outputs three rules (.o, .obj, .lo) for each
716 object that must be built with explicit rules. It just outputs
717 the rules required to build the kind of object considered: either
718 the two .o and .obj rules for usual objects, or the .lo rule for
721 * Change to Libtool support:
723 - Libtool tags are used with libtool versions that support them.
724 (I.e., with Libtool 1.5 or greater.)
726 - Automake is now able to handle setups where a libtool library is
727 conditionally installed in different directories, as in
730 lib_LTLIBRARIES = liba.la
732 pkglib_LTLIBRARIES = liba.la
734 liba_la_SOURCES = ...
736 * Changes to aclocal:
738 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
739 really evaluated, before it decides to include them in aclocal.m4.
740 This solves nasty problems with conditional redefinitions of
741 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
742 *.m4 files to be included in any project using these macros.
743 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
744 most famous instance of this bug.)
746 - Do not complain about missing conditionally AC_REQUIREd macros
747 that are not actually used. In 1.8.x aclocal would correctly
748 determine which of these macros were really needed (and include
749 only these in the package); unfortunately it would also require
750 all of them to be present in order to run. This created
751 situations were aclocal would not work on a tarball distributing
752 all the macros it uses. For instance running aclocal on a project
753 containing only the subset of the Gettext macros in use by the
754 project did not work, because gettext conditionally requires other
757 * Portability improvements:
759 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
760 tar-pax. The new option filename-length-max=99 helps diagnosing
761 filenames that are too long for tar-v7. (PR/414)
763 - Variables aumented with `+=' are now automatically flattened (i.e.,
764 trailing backslashes removed) and then wrapped around 80 colummns
765 (adding trailing backslashes). In previous versions, a long series
771 would result in a single-line definition of VAR that could possibly
772 exceed the maximum line length of some make implementations.
774 Non-augmented variables are still output as they are defined in
779 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
780 Works the same as the old Fortran 77 implementation; just replace
781 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
782 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
784 - Support for conditional _LISP.
786 - Support for conditional -hook and -local rules (PR/428).
788 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
790 - Automake will not write any Makefile.ins after the first error it
791 encounters. The previous Makefile.ins (if any) will be left in
792 place. (Warnings will not prevent output, but remember they can
793 be turned into errors with -Werror.)
795 - The restriction that SUBDIRS must contain direct children is gone.
798 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
799 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
803 * Long-standing bugs:
805 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
806 so that `make distclean' and `make maintainer-clean' can work.
808 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
810 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
812 - Polish diagnostic when no input file is found.
816 * Long-standing bugs:
818 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
819 overridden by the user.
821 - Honor PATH_SEPARATOR in various places of the Automake package, for
824 - Adjust dependency tracking mode detection to ICC 8.0's new output.
827 - Fix install-sh so it can install the `mv' binary... using `mv'.
829 - Fix tru64 dependency tracking for libtool objects.
831 - Work around Exuberant Ctags when creating a TAGS files in a directory
832 without files to scan but with subdirectories to include.
834 * Bugs introduced by 1.8:
836 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
837 not defined in the same conditions as the _LDADD that uses it.
839 - Do not warn when JAVAROOT is overridden, this is legitimate.
843 * Long-standing bugs:
845 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
846 or any of the other *dir variables contain a space.
848 Please note that Automake does not and cannot support spaces in
849 filenames that are involved during the build. This change affects
850 only installation paths, so that `make install' does not bomb out
851 in packages configured with
852 ./configure --prefix '/c/Program Files'
854 - Fix the depfiles output so it works with GNU sed (<4.1) even when
855 POSIXLY_CORRECT is set.
857 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
858 since Autoconf 2.54, which defines LIBOBJS itself.
860 - Fix a potential (but unlikely) race condition in parallel elisp
861 builds. (Introduced in 1.7.3.)
863 - Do not assume that users override _DEPENDENCIES in all conditions
864 where Automake will try to define them.
866 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
867 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
870 This fix also affects the $(mkdir_p) variable defined since
871 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
872 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
874 - Secure temporary directory creation in `make distcheck'. (PR/413)
876 - Do not generate two build rules for `parser.h' when the
877 parser appears in two different conditionals.
879 - Work around a Solaris 8 /bin/sh bug in the test for dependency
880 checking. Usually ./configure will not pick this shell; so this
881 fix only helps cases where the shell is forced to /bin/sh.
883 * Bugs introduced by 1.8:
885 - In some situations (hand-written `m4_include's), aclocal would
886 call the `File::Spec->rel2abs' method, which was only introduced
887 in Perl 5.6. This new version reestablish support Perl 5.005.
889 It is likely that the next major Automake releases will require at
890 least Perl 5.6. Consider upgrading your development environment
891 if you are still using the five-year-old Perl 5.005.
893 - Automake would sometimes fail to define rules for targets listed
894 in variables defined in multiple conditions. For instance on
900 it would define only the `a.$(OBJEXT): a.c' rule and omit the
901 `b.$(OBJEXT): b.c' rule.
903 * New sections in manual:
905 - Third-Party Makefiles: how to interface third party Makefiles.
906 - Upgrading: upgrading packages to newer Automake versions.
907 - Multiple Outputs: handling tools that produce many outputs.
911 * A (well known) portability bug slipped in the changes made to
912 install-sh in Automake 1.8.1. The broken install-sh would refuse to
913 install anything on Tru64.
915 * Fix install rules for conditionally built python files. (This never
920 * Bugs introduced by 1.8:
922 - Fix Config.pm import error with old Perl versions (at least
923 5.005_03). One symptom is that aclocal could not find its macro
926 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
927 created by `make install' are always world readable, even if the
928 installer happens to have an overly restrictive umask (e.g. 077).
929 This was a mistake and has been reverted. There are at least two
930 reasons why we must not use `-m 0755':
931 - it causes special bits like SGID to be ignored,
932 - it may be too restrictive (some setups expect 775 directories).
934 - Fix aclocal to honor definitions located in files which have been
935 m4_included manually. aclocal 1.8 had been updated to check
936 m4_included files for new requirements, but forgot that these
937 m4_included files can also provide new definitions.
939 Note that if you have such a setup, we recommend you get rid of
940 it. In the past, there was a reason to m4_include files manually:
941 aclocal used to duplicate entire M4 files into aclocal.m4, even
942 files that were distributed. Some packages were therefore
943 m4_including the distributed file directly, and playing some
944 tricks to ensure aclocal would not copy that file to aclocal.m4,
945 in order to limit the amount of duplication. Since aclocal 1.8.x
946 will precisely output m4_includes for local M4 files, we recommend
947 that you clean up your setup, removing all manual m4_includes and
948 letting aclocal output them.
950 - Output detailed menus in the Info version if the Automake manual,
951 so that Emacs can locate the indexes.
953 - configure.ac and configure were listed twice in DIST_COMMON (an
954 internal variable where Automake lists configury files to
955 distribute). This was harmless, but unaesthetic.
957 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
958 This was an issue only in the Automake package itself, not in
961 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
962 DEST:SRC. This was wrong, as some packages do
963 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
966 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
967 argument. This caused two kinds of failures:
968 - Rules installing data in a conditionally defined directory
969 failed when that directory was undefined. In this case no
970 argument was supplied.
971 - `make installdirs' failed, because several directories were
972 passed to $(mkdir_p). This was an issue only on platform
973 were $(mkdir_p) is implemented with `install-sh -d'.
974 $(mkdir_p) as been changed to accept 0 or more arguments, as
977 * Long-standing bugs:
979 - Fix an unexpected diagnostic occurring when users attempt
980 to override some internal variables that Automake appends to.
982 - aclocal now scans configure.ac for macro definitions (PR/319).
984 - Fix a portability issue with OSF1/Tru64 Make. If a directory
985 distributes files which are outside itself (this usually occurs
986 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
987 from a parent package), then `make distcheck' fails due to an
988 optimization performed by OSF1/Tru64 Make in its VPATH handling.
989 (tests/subpkg2.test failure)
991 - Fix another portability issue with Sun and OSF1/Tru64 Make.
992 In a VPATH-build configuration, `make install' would install
993 nobase_ files to wrong locations.
995 - Fix a Perl `uninitialized value' diagnostic occurring when
996 automake complains that a Texinfo file does not have a
997 @setfilename statement.
999 - Erase config.status.lineno during `make distclean'. This file
1000 can be created by config.status. Automake already knew about
1001 configure.lineno, but forgot config.status.lineno.
1003 - Distribute all files, even those which are built and installed
1004 conditionally. This change affects files listed in conditionally
1005 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1006 as well as those listed in conditionally defined dist_*_DATA,
1007 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1009 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1010 doesn't conform to POSIX.
1012 - Normalize help strings for configure variables and options added
1017 - Check for python2.4 in AM_PATH_PYTHON.
1019 * Spurious failures in test suite:
1021 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1022 tests/ltconv.test: fix failures with CVS Libtool.
1023 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1024 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1025 fix failures with old Texinfo versions.
1031 - The NEWS file is more verbose.
1035 - Autoconf 2.58 or greater is required.
1039 - Default source file names in the absence of a _SOURCES declaration
1040 are made by removing any target extension before appending `.c', so
1041 to make the libtool module `foo.la' from `foo.c', you only need to
1044 lib_LTLIBRARIES = foo.la
1045 foo_la_LDFLAGS = -module
1047 For backward compatibility, foo_la.c will be used instead of
1048 foo.c if this file exists or is the explicit target of a rule.
1049 However -Wobsolete will warn about this deprecated naming.
1051 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1052 of being hard-coded in each $(AR) invocation, so they can be
1053 substituted from configure.ac. This has been requested by people
1054 dealing with non-POSIX ar implementations.
1056 - New warning option: -Woverride. This will warn about any user
1057 target or variable definitions which override Automake
1060 - Texinfo rules back up and restore info files when makeinfo fails.
1062 - Texinfo rules now support the `html' target.
1063 Running this requires Texinfo 4.0 or greater.
1065 `html' is a new recursive target, so if your package mixes
1066 hand-crafted `Makefile.in's with Automake-generated
1067 `Makefile.in's, you should adjust the former to support (or
1068 ignore) this target so that `make html' recurses successfully. If
1069 you had a custom `html' rule in your `Makefile.am', it's better to
1070 rename it as `html-local', otherwise your rule will override
1071 Automake's new rule (you can check that by running `automake
1072 -Woverride') and that will stop the recursion to subdirectories.
1074 Last but not least, this `html' rule is declared PHONY, even when
1075 overridden. Fortunately, it appears that few packages use a
1076 non-PHONY `html' rule.
1078 - Any file which is m4_included from configure.ac will appear as a
1079 configure and Makefile.in dependency, and will be automatically
1082 - The rules for rebuilding Makefiles and Makefile.ins will now
1083 rebuild all Makefiles and all Makefile.ins at once when one of
1084 configure's dependencies has changed. This is considerably faster
1085 than previous implementations, where config.status and automake
1086 were run separately in each directory (this still happens when you
1087 change a Makefile.am locally, without touching configure.ac or
1088 friends). Doing this also solves a longstanding issue: these
1089 rebuild rules failed to work when adding new directories to the
1090 tree, forcing you to run automake manually.
1092 - For similar reasons, the rules to rebuild configure,
1093 config.status, and aclocal.m4 are now defined in all directories.
1094 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1095 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1096 should better define them in all directories. This is easily done
1097 using an AC_SUBST (make sure you prefix these dependencies with
1098 $(top_srcdir) since this variable will appear at different
1099 levels of the build tree).
1101 - aclocal will now use `m4_include' instead of copying local m4
1102 files into aclocal.m4. (Local m4 files are those you ship with
1103 your project, other files will be copied as usual.)
1105 Because m4_included files are automatically distributed, it means
1106 for most projects there is no point in EXTRA_DISTing the list of
1107 m4 files which are used. (You can probably get rid of
1108 m4/Makefile.am if you had one.)
1110 - aclocal will avoid touching aclocal.m4 when possible, so that
1111 Autom4te's cache isn't needlessly invalidated. This behavior can
1112 be switched off with the new `--force' option.
1114 - aclocal now uses Autoconf's --trace to detect macros which are
1115 actually used and will no longer include unused macros simply
1116 because they where mentioned. This was often the case for macros
1117 called conditionally.
1119 - New options no-dist and no-dist-gzip.
1121 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1122 py-compile, and ylwrap, now all understand --version and --help.
1124 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1125 links as part of the distclean target and including source files in
1128 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1129 argument. The latter can be used to override the default behavior
1130 (which is to abort).
1132 - Automake will exit with $? = 63 on version mismatch. (So does
1133 Autoconf 2.58) missing knows this, and in this case it will
1134 emulate the tools as if they were absent. Because older versions
1135 of Automake and Autoconf did not use this exit code, this change
1136 will only be useful in projects generated with future versions of
1139 - When using AC_CONFIG_FILES with multiple input files, Automake
1140 generates the first ".in" input file for which a ".am" exists.
1141 (Former versions would try to use only the first input file.)
1143 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1144 idiom to disable byte-compilation of lisp_LISP files, it is
1145 recommended that you switch to using lisp_DATA. Note that
1146 this is not strictly equivalent: lisp_DATA will install elisp
1147 files even if emacs is not installed, while *_LISP do not
1148 install anything unless emacs is found.
1150 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1151 available. This selection is achieved through the Makefile
1152 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1153 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1154 `$(install_sh) -m 0755 -d'.
1158 - Because `mkdir -p' is available on most platforms, and we can use
1159 `install-sh -d' when it is not, the use of the mkinstalldirs
1160 script is being phased out. `automake --add-missing' no longer
1161 installs it, and if you remove mkinstalldirs from your package,
1162 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1164 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1165 gettextize and autopoint will install it when needed. Automake
1166 will continue to define the $(mkinstalldirs) and to distribute
1167 mkinstalldirs when this script is in the source tree.
1169 - AM_PROG_CC_STDC is now empty. The content of this macro was
1170 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1171 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1172 renaming should be safe, even if you have to support several,
1173 versions of Automake, because AC_PROG_CC defines this variable
1174 since Autoconf 2.54.)
1176 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1177 variable to override the aclocal.m4 dependencies computed
1178 (inaccurately) by older versions of Automake. Because Automake
1179 now tracks configure's m4 dependencies accurately (see m4_include
1180 above), the use of ACLOCAL_M4_SOURCES should be considered
1181 obsolete and will be flagged as such when running `automake
1186 - Defining programs conditionally using Automake conditionals no
1187 longer leads to a combinatorial explosion. The following
1188 construct used to be troublesome when used with dozens of
1203 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1205 - Due to implementation constraints, previous versions of Automake
1206 proscribed multiple conditional definitions of some variables
1216 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1217 This restriction has been lifted, and these variables now
1218 support multiple conditional definitions as do other variables.
1220 - Cleanup the definitions of $(distdir) and $(top_distdir).
1221 $(top_distdir) now points to the root of the distribution
1222 directory created during `make dist', as it did in Automake 1.4,
1223 not to the root of the build tree as it did in intervening
1224 versions. Furthermore these two variables are now only defined in
1225 the top level Makefile, and passed to sub-directories when running
1228 - The --no-force option now correctly checks the Makefile.in's
1229 dependencies before deciding not to update it.
1231 - Do not assume that make files are called Makefile in cleaning rules.
1233 - Update .info files in the source tree, not in the build tree. This
1234 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1235 used to update these files in the build tree (previous versions did
1236 it in the source tree too), and it caused several problems, varying
1237 from mere annoyance to portability issues.
1239 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1240 when --add-missing and --force-missing are used. For backward
1241 compatibility --add-missing will continue to install COPYING (in
1242 `gnu' strictness) when none of these three files exist, but this
1243 use is deprecated: you should better choose a license yourself and
1244 install it once for all in your source tree (and in your code
1247 - Fix ylwrap so that it does not overwrite header files that haven't
1248 changed, as the inline rule already does.
1250 - User-defined rules override automake-defined rules for the same
1251 targets, even when rules do not have commands. This is not new
1252 (and was documented), however some of the automake-generated
1253 rules have escaped this principle in former Automake versions.
1254 Rules for the following targets are affected by this fix:
1256 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1257 info, info-am, install-data-am, install-exec-am, install-info,
1258 install-info-am, install-man, installcheck-am, maintainer-clean,
1259 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1260 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1262 Practically it means that an attempt to supplement the dependencies
1263 of some target, as in
1265 clean: my-clean-rule
1267 will now *silently override* the automake definition of the
1268 rule for this target. Running `automake -Woverride' will diagnose
1269 all such overriding definitions.
1271 It should be noted that almost all these targets support a *-local
1272 variant that is meant to supplement the automake-defined rule
1273 (See node `Extending' in the manual). The above rule should
1276 clean-local: my-clean-rule
1278 These *-local targets have been documented since at least
1279 Automake 1.2, so you should not fear the change if you have
1280 to support multiple automake versions.
1284 - The Automake manual is now distributed under the terms of the GNU FDL.
1286 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1288 - core dumps are no longer removed by the cleaning rules. There are
1289 at least three reasons for this:
1290 1. These files should not be created by any build step,
1291 so their removal do not fit any of the cleaning rules.
1292 Actually, they may be precious to the developer.
1293 2. If such file is created during a build, then it's clearly a
1294 bug Automake should not hide. Not removing the file will
1295 cause `make distcheck' to complain about its presence.
1296 3. Operating systems have different naming conventions for
1297 core dump files. A core file on one system might be a
1298 completely legitimate data file on another system.
1300 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1301 defined by Automake. This means that any definition in the
1302 environment will be used, unless overridden in the Makefile.am or
1303 on the command line. The old behavior, where these variables were
1304 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1305 AC_ARG_VARing each variable from configure.ac.
1307 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1308 documented. (The is not a new feature, these variables have
1309 been there since at least Automake 1.4.)
1311 Bugs fixed in 1.7.9:
1312 * Fix install-strip to work with nobase_ binaries.
1313 * Fix renaming of #line directives in ylwrap.
1314 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)

1317 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1318 * Fix detection of Debian's install-info, broken since version 1.5.
1319 (Debian bug #213524).
1320 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1321 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1323 Bugs fixed in 1.7.7:
1324 * The implementation of automake's --no-force option is unreliable,
1325 so this option is ignored in this version. A real fix will appear in
1326 Automake 1.8. (Debian Bug #206299)
1327 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1328 argument is given. (PR/399)
1329 * Do not warn about leading `_' in variable names, even with -Wportability.
1330 * Support user redefinitions of TEXINFO_TEX.
1331 * depcomp: support AIX Compiler version 6.
1332 * Fix missing rebuilds during `make dist' with BSD make.
1333 (Could produce tarballs containing out-of-date files.)
1334 * Resurrect multilib support.
1335 * Noteworthy manual updates:
1336 - Extending aclocal: how to write m4 macros that won't trigger warnings
1338 - A Shared Library: Rewrite and split into subsections.
1340 Bugs fixed in 1.7.6:
1341 * Fix depcomp's icc mode for ICC 7.1.
1342 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1343 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1344 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1345 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1346 * Remove Latin-1 characters from elisp-comp.
1347 * Update the manual's @dircategory to match the Free Software Directory.
1349 Bugs fixed in 1.7.5:
1350 * Update install-sh's license to remove an advertising clause.
1351 (Debian bug #191717)
1352 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1353 that caused invalid Makefile.ins to be generated.
1354 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1355 * New FAQ entry: renamed objects.
1357 Bugs fixed in 1.7.4:
1358 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1359 the Emacs implementation)
1360 * Fix output of aclocal.m4 dependencies in subdirectories.
1361 * Use `mv -f' instead of `mv' in fastdep rules.
1362 * Upgrade mdate-sh to work on OS/2.
1363 * Don't byte-compile elisp files when ELCFILES is set empty.

1370 * `make install' will build `BUILT_SOURCES' first.
1371 * Minor documentation fixes.
1373 Bugs fixed in 1.7.3:
1374 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1375 * Query distutils for `pythondir' and `pythonexecdir', instead of
1376 using an hardcoded path. This should allow builds on 64-bit
1377 distributions that usually use lib64/ instead of lib/.
1378 * AM_PATH_PYTHON will also search for python2.3.
1379 * elisp files are now built all at once instead of one by one. Besides
1380 incurring a speed-up, this is required to support interdependent elisp files.
1381 * Support for DJGPP:
1382 - `make distcheck' will now work in `_inst/' and `_build' instead
1383 of `=inst/' and `=build/'
1384 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1385 - install/uninstall `*.i[0-9][0-9]'-style info files
1386 - more changes that affect only the Automake package (not its output)
1387 * Fix some incompatibilities with upcoming perl-5.10.
1388 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1389 PACKAGE and VERSION.
1391 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1392 is troublesome with gcc and Solaris compilers. (PR/385)
1393 - makedepend mode: work with Libtool. (PR/385 too)
1395 * better support for unusual gettext setups, such as multiple po/ directories
1397 - Flag missing po/ and intl/ directories as warnings, not errors.
1398 - Disable these warnings if po/ does not exist.
1399 * Noteworthy manual updates:
1401 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1403 - Document `AM_YFLAGS = -d'. (PR/382)
1405 Bugs fixed in 1.7.2:
1406 * Fix installation and uninstallation of Info files built in subdirectories.
1407 * Do not run `./configure --with-included-gettext' during `make distcheck'
1408 if AM_GNU_GETTEXT([external]) is used.
1409 * Correctly uninstall renamed man pages.
1410 * Do not strip escaped newline in variables defined in one condition
1411 and augmented in another condition.
1412 * Fix ansi2knr rules for LIBOBJS sources.
1413 * Clean all known Texinfo index files, not only those which appear to
1414 be used, because we cannot know wich indexes are used in included files.
1415 (PR/375, Debian Bug #168671)
1416 * Honor only the first @setfilename seen in a Texinfo file.
1417 * Treat "required file X not found" diagnostics as errors (exit status 1).
1418 * Don't complain that a required file is not found when it is a Makefile
1420 * Don't use single suffix inference rules when building `.info'-less
1421 Info files, for the sake of Solaris make.
1422 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1423 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1424 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1425 * Fix building of deansified files from subdirectories. (PR/370)
1426 * Add missing `fi' in the .c->.obj rules.
1427 * Improve install-sh to work even when names contain spaces or certain
1428 (but not all) shell metachars.
1429 * Fix the following spurious failures in the test suite:
1430 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1431 * Noteworthy manual updates:
1432 - Augment the section about BUILT_SOURCES.
1433 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1435 Bugs fixed in 1.7.1:
1436 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1438 * Aclocal should now recognize macro names containing parentheses, e.g.
1439 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1440 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1442 * Install Python files even if they were built. (PR/369)
1443 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1444 version might not be defined in the latter. (PR/358)
1445 * Reorder arguments passed to a couple of commands, so things works
1446 when POSIXLY_CORRECT=1.
1447 * Fix a regex that can cause Perl to segfault on large input.
1449 * Fix distribution of packages that have some sources defined conditionally,
1450 as in the `Conditional compilation using Automake conditionals' example
1452 * Fix spurious test suite failures on IRIX.
1453 * Don't report a required variable as undefined if it has been
1454 defined conditionally for the "right" conditions.
1455 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1456 `make distcheck' fails.
1457 * Fix distribution of included Makefile fragment, so we don't create
1458 spurious directories in the distribution. (PR/366)
1459 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1462 * Autoconf 2.54 is required.
1463 * `aclocal' and `automake' will no longer warn about obsolete
1464 configure macros. This is done by `autoconf -Wobsolete'.
1465 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1466 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1467 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1468 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1469 `configure.ac' for you.
1470 * Support for per-program and per-library `_CPPFLAGS'.
1471 * New `ctags' target (builds CTAGS files).
1472 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1473 (see `automake --help' or the manual for a list of them).
1474 * Honor the WARNINGS environment variable.
1475 * Omit the call to depcomp when using gcc3: call the compiler directly.
1476 * A new option, std-options, tests that programs support --help and --version
1477 when `make installcheck' is run. This is enabled by --gnits.
1478 * Texinfo rules now support the `ps' and `pdf' targets.
1479 * Info files are now created in the build directory, not the source directory.
1480 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1482 * `make distcheck' will enforce DESTDIR support by attempting
1484 * `+=' can be used in conditionals, even if the augmented variable
1485 was defined for another condition.
1486 * Makefile fragments (inserted with `include') are always distributed.
1487 * Use Autoconf's --trace interface to inspect configure.ac and get
1488 a more accurate view of it.
1489 * Add support for extending aclocal's default macro search path
1490 using a `dirlist' file within the aclocal directory.
1491 * automake --output-dir is deprecated.
1492 * The part of the distcheck target that checks whether uninstall actually
1493 removes all installed files has been moved in a separate target,
1494 distuninstallcheck, so it can be overridden easily.
1498 * Support for AM_INIT_GETTEXT([external])
1499 * Bug fixes, including:
1500 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1501 - nobase_ programs and scripts honor --program-transform correctly.
1502 - Erase configure.lineno during `make distclean'.
1503 - Erase YACC and LEX outputs during `make maintainer-clean'.
1506 * Many bug fixes, including:
1507 - Requiring the current version works.

1518 - Don't choke on AM_LDFLAGS definitions.
1519 - Clean libtool objects from subdirectories.
1520 - Allow configure variables with reserved suffix and unknown prefix
1521 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1522 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1525 * Autoconf 2.52 is required.
1526 * automake no longer run libtoolize.
1527 This is the job of autoreconf (from GNU Autoconf).
1528 * `dist' generates all the archive flavors, as did `dist-all'.
1529 * `dist-gzip' generates the Gzip tar file only.
1530 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1531 explosion. Makefile.in's keep a reasonable size.
1532 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1533 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1535 * `#line' of Lex and Yacc files are properly set.
1536 * EXTRA_DIST can contain generated directories.
1537 * Support for dot-less extensions in suffix rules.
1538 * The part of the distcheck target that checks whether distclean actually
1539 cleans all built files has been moved in a separate target, distcleancheck,
1540 so it can be overridden easily.
1541 * `make distcheck' will pass additional options defined in
1542 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1543 * Fixed CDPATH portability problems, in particular for MacOS X.
1544 * Fixed handling of nobase_ targets.
1545 * Fixed support of implicit rules leading to .lo objects.
1546 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1547 * Added uninstall-hook target
1548 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1549 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1550 (Note that "pkgname" is not "tarname", see the manual for details.)
1551 It is also possible to pass a list of global Automake options as
1552 first argument to this new form of AM_INIT_AUTOMAKE.
1553 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1554 to be a real assembler.
1555 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1556 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1557 * aclocal and automake are also installed with the version number
