5 - automake now generates silenced rules for texinfo outputs.
7 - The deprecated options `--output-dir', `--Werror' and `--Wno-error'
12 - New `cscope' target to build a cscope database for the source tree.
14 * Changes to Automake-generated testsuite harnesses:
16 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
17 and unexpected or internal error, or a failure to set up the test case
18 scenario) have their outcome reported as an 'ERROR' now. Previous
19 versions of automake reported such an outcome as a 'FAIL' (the only
20 difference with normal failures being that hard errors were counted
21 as failures even when the test originating them was listed in
24 - The testsuite summary displayed by the parallel-test harness has a
25 completely new format, that always list the numbers of passed, failed,
26 xfailed, xpassed, skipped and errored tests, even when these numbers
27 are zero (but using smart coloring when the color-tests option is in
30 - The default testsuite driver offered by the 'parallel-tests' option is
31 now implemented (partly at least) with the help of automake-provided
32 auxiliary scripts (e.g., `test-driver'), instead of relying entirely
33 on code in the generated Makefile.in.
34 This has two noteworthy implications. The first one is that projects
35 using the `parallel-tests' option should now either run automake with
36 the `--add-missing' option, or manually copy the `test-driver' script
37 into their tree. The second, and more important, implication is that
38 now, when the `parallel-tests' option is in use, TESTS_ENVIRONMENT can
39 not be used anymore to define a test runner, and the command specified
40 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
41 program or script. For example, this is still a valid usage (albeit
45 if test -n '$(STRICT_TESTS)'; then \
50 LOG_COMPILER = $(SHELL) $$maybe_errexit
52 while this is not anymore:
55 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
60 run_with_perl_or_shell () \
62 if grep -q '^#!.*perl' $$1; then
68 LOG_COMPILER = run_with_per_or_shell
70 - The package authors can now use customary testsuite drivers within
71 the framework provided by the 'parallel-tests' testsuite harness.
72 Consistently with the existing syntax, this can be done by defining
73 special makefile variables `LOG_DRIVER' and `<ext>_LOG_DRIVER'.
75 - A new developer-reserved variable `AM_TESTS_FD_REDIRECT' can be used
76 to redirect/define file descriptors used by the test scripts.
78 - The parallel-tests harness generates now, in addition the `.log' files
79 holding the output produced by the test scripts, a new set of `.trs'
80 files, holding "metadata" derived by the execution of the test scripts;
81 among such metadata are the outcomes of the test cases run by a script.
83 - Initial and still experimental support for the TAP test protocol is
86 * WARNING: Future backward-incompatibilities!
88 - The Automake support for automatic de-ANSI-fication will be removed in
89 the next major Automake release (1.12).
91 * Miscellaneous changes:
93 - The `dist' and `dist-all' targets now can run compressors in parallel.
95 - The `lzma' compression scheme and associated automake option `dist-lzma'
96 is obsoleted by `xz' and `dist-xz' due to upstream changes.
98 - "make dist" can now create lzip-compressed tarballs.
100 - You may adjust the compression options used in dist-xz and dist-bzip2.
101 The default is still -9 for each, but you may specify a different
102 level via the XZ_OPT and BZIP2 envvars respectively. E.g.,
103 "make dist-xz XZ_OPT=-7" or "make dist-xz BZIP2=-5"
105 - Messages of types warning or error from `automake' and `aclocal' are now
106 prefixed with the respective type, and presence of -Werror is noted.
108 - The `compile' script now converts some options for MSVC for a better
109 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
111 - Automake's early configure-time sanity check now tries to avoid sleeping
112 for a second, which slowed down cached configure runs noticeably. In that
113 case, it will check back at the end of the configure script to ensure that
114 at least one second has passed, to avoid time stamp issues with makefile
115 rules rerunning autotools programs.
117 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES and
118 adds them to the normal list of dependencies, but without overwriting the
119 foo_DEPENDENCIES variable, which is normally computed by automake.
121 - C source and header files derived from non-distributed Yacc sources are
122 now removed by "make clean", not only by "make maintainer-clean".
124 - A developer that needs to pass specific flags to configure at "make
125 distcheck" time can now, and indeed he's advised to, do so by defining
126 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
127 instead of the old DISTCHECK_CONFIGURE_FLAGS.
128 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
129 user; still, the old Makefile.am files that used to define it should
130 still continue to work as before.
134 - Lots of minor bugfixes.
136 * Bugs introduced by 1.11:
138 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
139 trailing white space in the test list (`TESTS = foo $(EMPTY)'), and
140 does not report spurious successes when used with concurrent FreeBSD
141 make (e.g., "make check -j3").
143 - The `silent-rules' option now also silences all compile rules if dependency
144 tracking is disabled. Also, when `silent-rules' is not used, the output from
145 `make' does not contain spurious extra lines with only a backslash in them
146 any more; it now again matches that from pre-1.11 Automake.
148 - The `dist-xz' option now uses `xz -9' for maximum compression.
150 - The AM_COND_IF macro also works if the shell expression for the conditional
151 is no longer valid for the condition.
153 * Long standing bugs:
155 - Automake now warns about more primary/directory invalid combinations,
156 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
158 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
159 even if the `--prefix' argument pointed outside of a system directory.
160 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
161 `get_python_lib' function if it points outside the configured prefix,
162 unless the `--prefix' argument was either `/usr' or below `/System'.
164 - The testsuite does not try to change the mode of `ltmain.sh' files from
165 a Libtool installation (symlinked to test directories) any more.
167 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
168 tools are preferred in a cross-compile setup.
170 - The distribution is tarred up with mode 755 now by the `dist*' targets.
171 This fixes a race condition where untrusted users could modify files
172 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
173 build directory was world-searchable. This is CVE-2009-4029.
175 - Several scripts as well as the parallel-tests testsuite driver now
176 exit with the right exit status upon receiving a signal.
178 - A per-Makefile.am setting of -Werror does not carry over to the
179 handling of other Makefile.am files any more.
181 - The order of Yacc and Lex flags is fixed to be consistent with other
182 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
183 $(LFLAGS), so that the user variables override the developer variables.
185 - Rules generated by Automake now try harder to not change any files when
186 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
187 Yacc source files and the rule to update config.h.
189 - The code for automatic dependency tracking works around a Solaris
190 make bug triggered by sources containing repeated slashes when the
191 `subdir-objects' option was used.
193 - Automake now detects the presence of the `-d' flag in the various
194 `*YFLAGS' variables even when their definitions involve indirections
195 through other variables, such as in:
197 AM_YFLAGS = $(foo_opts)
199 - Automake now complains if a `*YFLAGS' variable has any conditional
200 content, not only a conditional definition.
202 - Explicit enabling and/or disabling of Automake warning categories
203 through the `-W...' options now always takes precedence over the
204 implicit warning level implied by Automake strictness (foreign, gnu
205 or gnits), regardless of the order in which such strictness and
206 warning flags appear. For example, a setting like:
207 AUTOMAKE_OPTIONS = -Wall --foreign
208 will cause the warnings in category `portability' to be enabled, even
209 if those warnings are by default disabled in `foreign' strictness.
211 - The parallel-tests driver now does not produce erroneous results
212 with Tru64/OSF 5.1 sh upon unreadable log files any more.
214 - The makedepend and hp depmodes now works better with VPATH builds.
216 - Java sources specified with check_JAVA are not compiled anymore upon
217 "make all", but only upon "make check".
219 - Now aclocal and automake, when they've to spawn autoconf or autom4te
220 processes, honour the configure-time definitions of AUTOCONF and
225 * Version requirements:
227 - Autoconf 2.62 or greater is required.
229 * Changes to aclocal:
231 - The autoconf version check implemented by aclocal in aclocal.m4
232 (and new in Automake 1.10) is degraded to a warning. This helps
233 in the common case where the Autoconf versions used are compatible.
235 * Changes to automake:
237 - The automake program can run multiple threads for creating most
238 Makefile.in files concurrently, if at least Perl 5.7.2 is available
239 with interpreter-based threads enabled. Set the environment variable
240 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
241 enable this experimental feature.
243 * Changes to Libtool support:
245 - Libtool generic flags are now passed to the install and uninstall
248 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
249 config.lt is removed correctly now.
253 - subdir-object mode works now with Fortran (F77, FC, preprocessed
254 Fortran, and Ratfor).
256 - For files with extension .f90, .f95, .f03, or .f08, the flag
257 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
259 - Files with extension .sx are also treated as preprocessed assembler.
261 - The default source file extension (.c) can be overridden with
262 AM_DEFAULT_SOURCE_EXT now.
264 - Python 3.0 is supported now, Python releases prior to 2.0 are no
267 - AM_PATH_PYTHON honors python's idea about the site directory.
269 - There is initial support for the Vala programming language, when using
272 * Miscellaneous changes:
274 - Automake development is done in a git repository on Savannah now, see
276 http://git.sv.gnu.org/gitweb/?p=automake.git
278 A read-only CVS mirror is provided at
280 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
281 checkout -d automake HEAD
283 - "make dist" can now create xz-compressed tarballs,
284 as well as (deprecated?) lzma-compressed tarballs.
286 - `automake --add-missing' will by default install the GPLv3 file as
287 COPYING if it is missing. It will also warn that the license file
288 should be added to source control. Note that Automake will never
289 overwrite an existing COPYING file, even when the `--force-missing'
292 - The manual is now distributed under the terms of the GNU FDL 1.3.
294 - Automake ships and installs man pages for automake and aclocal now.
296 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
298 - install-sh supports -C, which does not update the installed file
299 (and its time stamps) if the contents did not change.
301 - The `gnupload' script has been revamped.
303 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
305 - The targets `install' and `uninstall' are more efficient now, in that
306 for example multiple files from one Automake variable such as
307 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
308 invocation if they do not have to be renamed.
310 Both install and uninstall may sometimes enter (`cd' into) the target
311 installation directory now, when no build-local scripts are used.
313 Both install and uninstall do not fail anymore but do nothing if an
314 installation directory variable like `bindir' is set to the empty string.
316 For built-in rules, `make install' now fails reliably if installation
317 of a file failed. Conversely, `make uninstall' even succeeds when
318 issued multiple times.
320 These changes may need some adjustments from users: For example,
321 some `install' programs refuse to install multiple copies of the
322 same file in one invocation, so you may need to remove duplicate
323 entries from file lists.
325 Also, within one set of files, say, nobase_data_DATA, the order of
326 installation may be changed, or even unstable among different hosts,
327 due to the use of associative arrays in awk. The increased use of
328 awk matches a similar move in Autoconf to provide for better scaling.
330 Further, most undocumented per-rule install command variables such as
331 binSCRIPT_INSTALL have been removed because they are not needed any
332 more. Packages which use them should be using the appropriate one of
333 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
334 counterpart, depending on the type of files and the need for automatic
335 target directory creation.
337 - The "deleted header file problem" for *.m4 files is avoided by
338 stub rules. This allows `make' to trigger a rerun of `aclocal'
339 also if some previously needed macro file has been removed.
341 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
342 an otherwise up to date tree.
344 - The `color-tests' option causes colored test result output on terminals.
346 - The `parallel-tests' option enables a new test driver that allows for
347 parallel test execution, inter-test dependencies, lazy test execution
348 for unit-testing, re-testing only failed tests, and formatted result output
349 as RST (reStructuredText) and HTML. Enabling this option may require some
350 changes to your test suite setup; see the manual for details.
352 - The `silent-rules' option enables Linux kernel-style silent build output.
353 This option requires the widely supported but non-POSIX `make' feature
354 of recursive variable expansion, so do not use it if your package needs
355 to build with `make' implementations that do not support it.
357 To enable less verbose build output, the developer has to use the Automake
358 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
359 macro. The user may then set the default verbosity by passing the
360 `--enable-silent-rules' option to `configure'. At `make' run time, this
361 default may be overridden using `make V=0' for less verbose, and `make V=1'
362 for backward-compatible verbose output.
364 - New prefix `notrans_' for manpages which should not be transformed
365 by --program-transform.
367 - New macro AM_COND_IF for conditional evaluation and conditional
370 - For AC_CONFIG_LINKS, if source and destination are equal, do not
371 remove the file in a non-VPATH build. Such setups work with Autoconf
374 - AM_MAINTAINER_MODE now allows for an optional argument specifying
377 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
378 useful especially for multi-line values.
380 - Automake's early configure-time sanity check now diagnoses an
381 unsafe absolute source directory name and makes configure fail.
383 - The Automake macros and rules cope better with whitespace in the
384 current directory name, as long as the relative path to `configure'
385 does not contain whitespace. To this end, the values of `$(MISSING)'
386 and `$(install_sh)' may contain suitable quoting, and their expansion
387 might need `eval'uation if used outside of a makefile. These
388 undocumented variables may be used in several documented macros such
389 as $(AUTOCONF) or $(MAKEINFO).
393 * Long standing bugs:
395 - Fix aix dependency tracking for libtool objects.
397 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
398 unnecessary use of the `compile' script.
400 - For nobase_*_LTLIBRARIES with nonempty directory components, the
401 correct `-rpath' argument is used now.
403 - `config.status --file=Makefile depfiles' now also works with the
404 extra quoting used internally by Autoconf 2.62 and newer
405 (it used to work only without the `--file=' bit).
407 - The `missing' script works better with versioned tool names.
409 - Semantics for `missing help2man' have been revamped:
411 Previously, if `help2man' was not present, `missing help2man' would have
412 the following semantics: if some man page was out of date but present, then
413 a warning would be printed, but the exit status was 0. If the man page was
414 not present at all, then `missing' would create a replacement man page
415 containing an error message, and exit with a status of 2. This does not play
416 well with `make': the next run will see this particular man page as being up
417 to date, and will only error out on the next generated man page, if any;
418 repeat until all pages are done. This was not desirable.
420 These are the new semantics: if some man page is not present, and help2man
421 is not either, then `missing' will warn and generate the replacement page
422 containing the error message, but exit successfully. However, `make dist'
423 will ensure that no such bogus man pages are packaged into a tarball.
425 - Targets provided by automake behave better with `make -n', in that they
426 take care not to create files.
428 - `config.status Makefile... depfiles' works fine again in the presence of
429 disabled dependency tracking.
431 - The default no-op recursive rules for these targets also work with BSD make
432 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
434 - `make distcheck' works also when both a directory and some file below it
435 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
437 - Texinfo dvi, ps, pdf, and html output files are not removed upon
438 `make mostlyclean' any more; only the LaTeX by-products are.
440 - Renamed objects also work with the `subdir-objects' option and
441 source file languages which Automake does not know itself.
443 - `automake' now correctly complains about variable assignments which are
444 preceded by a comment, extend over multiple lines with backslash-escaped
445 newlines, and end in a comment sign. Previous versions would silently
446 and wrongly ignore such assignments completely.
448 * Bugs introduced by 1.10:
450 - Fix output of dummy dependency files in presence of post-processed
451 Makefile.in's again, but also cope with long lines.
453 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
454 that have been declared as programs in the same Makefile.
455 This is for consistency with the analogous change to TESTS in 1.10.
457 - Fix order of standard includes to again be `-I. -I$(srcdir)',
458 followed by directories containing config headers.
462 * Version requirements:
464 - Autoconf 2.60 or greater is required.
466 - Perl 5.6 or greater is required.
468 * Changes to aclocal:
470 - aclocal now also supports -Wmumble and -Wno-mumble options.
472 - `dirlist' entries (for the aclocal search path) may use shell
473 wildcards such as `*', `?', or `[...]'.
475 - aclocal supports an --install option that will cause system-wide
476 third-party macros to be installed in the local directory
477 specified with the first -I flag. This option also uses #serial
478 lines in M4 files to upgrade local macros.
480 The new aclocal options --dry-run and --diff help to review changes
481 before they are installed.
483 - aclocal now outputs an autoconf version check in aclocal.m4 in
484 projects using automake.
486 For a few years, automake and aclocal have been calling autoconf
487 (or its underlying engine autom4te) to accurately retrieve the
488 data they need from configure.ac and its siblings. Doing so can
489 only work if all autotools use the same version of autoconf. For
490 instance a Makefile.in generated by automake for one version of
491 autoconf may stop working if configure is regenerated with another
492 version of autoconf, and vice versa.
494 This new version check ensures that the whole build system has
495 been generated using the same autoconf version.
497 * Support for new Autoconf macros:
499 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
501 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
502 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
503 in different directories. However, only one instance of such a
504 library objects directory is supported.
506 * Change to Libtool support:
508 - Libtool generic flags (those that go before the --mode=MODE option)
509 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
511 * Yacc and Lex changes:
513 - The rebuild rules for distributed Yacc and Lex output will avoid
514 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
517 - ylwrap is now always used for lex and yacc source files,
518 regardless of whether there is more than one source per directory.
522 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
523 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
524 tracking, unlike non-preprocessed assembler (*.s).
526 - subdir-object mode works now with Assembler. Automake assumes
527 that the compiler understands `-c -o'.
529 - Preprocessed assembler (*.S) compilation now also honors
530 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
532 - Improved support for Objective C:
533 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
534 - A new section of the manual documents the support.
536 - New support for Unified Parallel C:
537 - AM_PROG_UPC looks for a UPC compiler.
538 - A new section of the manual documents the support.
540 - Per-target flags are now correctly handled in link rules.
542 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
543 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
544 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
545 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
547 The fix for compiler flags (i.e., using maude_CFLAGS instead of
548 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
549 is expected to work (and actually works during compilation).
551 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
552 "in addition to" breaks backward compatibility with older versions.
553 If your package used both variables, as in
555 AM_LDFLAGS = common flags
557 a_LDFLAGS = more flags
560 and assumed *_LDFLAGS would sum up, you should rewrite it as
562 AM_LDFLAGS = common flags
564 a_LDFLAGS = $(AM_LDFLAGS) more flags
567 This new behavior of *_LDFLAGS is more coherent with other
568 per-target variables, and the way *_LDFLAGS variables were
569 considered internally.
571 * New installation targets:
573 - New targets mandated by GNU Coding Standards:
578 By default they will only install Texinfo manuals.
579 You can customize them with *-local variants:
585 - The undocumented recursive target `uninstall-info' no longer exists.
586 (`uninstall' is in charge of removing all possible documentation
587 flavors, including optional formats such as dvi, ps, or info even
588 when `no-installinfo' is used.)
590 * Miscellaneous changes:
592 - Automake no longer complains if input files for AC_CONFIG_FILES
593 are specified using shell variables.
595 - clean, distribution, or rebuild rules are normally disabled for
596 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
597 AC_CONFIG_LINK specified using shell variables. However, if these
598 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
599 be able to output rules anyway.
600 (See the Automake documentation for AC_CONFIG_FILES.)
602 - $(EXEEXT) is automatically appended to filenames of TESTS
603 that have been declared as programs in the same Makefile.
604 This is mostly useful when some check_PROGRAMS are listed in TESTS.
606 - `-Wportability' has finally been turned on by default for `gnu' and
607 `gnits' strictness. This means, automake will complain about %-rules
608 or $(GNU Make functions) unless you switch to `foreign' strictness or
609 use `-Wno-portability'.
611 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
612 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
613 $(mkdir_p) variable is still defined (to the same value as
614 $(MKDIR_P)) but should be considered obsolete. If you are using
615 $(mkdir_p) in some of your rules, please plan to update them to
616 $(MKDIR_P) at some point.
618 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
619 They still work in this release, but may be withdrawn in a future one.
621 - Inline compilation rules for gcc3-style dependency tracking are
624 - Automake installs a "Hello World!" example package in $(docdir).
625 This example is used throughout the new "Autotools Introduction"
626 chapter of the manual.
630 * Makefile.in bloat reduction:
632 - Inference rules are used to compile sources in subdirectories when
633 the `subdir-objects' option is used and no per-target flags are
634 used. This should reduce the size of some projects a lot, because
635 Automake used to output an explicit rule for each such object in
638 - Automake no longer outputs three rules (.o, .obj, .lo) for each
639 object that must be built with explicit rules. It just outputs
640 the rules required to build the kind of object considered: either
641 the two .o and .obj rules for usual objects, or the .lo rule for
644 * Change to Libtool support:
646 - Libtool tags are used with libtool versions that support them.
647 (I.e., with Libtool 1.5 or greater.)
649 - Automake is now able to handle setups where a libtool library is
650 conditionally installed in different directories, as in
653 lib_LTLIBRARIES = liba.la
655 pkglib_LTLIBRARIES = liba.la
657 liba_la_SOURCES = ...
659 * Changes to aclocal:
661 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
662 really evaluated, before it decides to include them in aclocal.m4.
663 This solves nasty problems with conditional redefinitions of
664 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
665 *.m4 files to be included in any project using these macros.
666 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
667 most famous instance of this bug.)
669 - Do not complain about missing conditionally AC_REQUIREd macros
670 that are not actually used. In 1.8.x aclocal would correctly
671 determine which of these macros were really needed (and include
672 only these in the package); unfortunately it would also require
673 all of them to be present in order to run. This created
674 situations were aclocal would not work on a tarball distributing
675 all the macros it uses. For instance running aclocal on a project
676 containing only the subset of the Gettext macros in use by the
677 project did not work, because gettext conditionally requires other
680 * Portability improvements:
682 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
683 tar-pax. The new option filename-length-max=99 helps diagnosing
684 filenames that are too long for tar-v7. (PR/414)
686 - Variables aumented with `+=' are now automatically flattened (i.e.,
687 trailing backslashes removed) and then wrapped around 80 colummns
688 (adding trailing backslashes). In previous versions, a long series
694 would result in a single-line definition of VAR that could possibly
695 exceed the maximum line length of some make implementations.
697 Non-augmented variables are still output as they are defined in
702 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
703 Works the same as the old Fortran 77 implementation; just replace
704 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
705 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
707 - Support for conditional _LISP.
709 - Support for conditional -hook and -local rules (PR/428).
711 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
713 - Automake will not write any Makefile.ins after the first error it
714 encounters. The previous Makefile.ins (if any) will be left in
715 place. (Warnings will not prevent output, but remember they can
716 be turned into errors with -Werror.)
718 - The restriction that SUBDIRS must contain direct children is gone.
721 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
722 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
726 * Long standing bugs:
728 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
729 so that `make distclean' and `make maintainer-clean' can work.
731 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
733 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
735 - Polish diagnostic when no input file is found.
739 * Long standing bugs:
741 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
742 overridden by the user.
744 - Honor PATH_SEPARATOR in various places of the Automake package, for
747 - Adjust dependency tracking mode detection to ICC 8.0's new output.
750 - Fix install-sh so it can install the `mv' binary... using `mv'.
752 - Fix tru64 dependency tracking for libtool objects.
754 - Work around Exuberant Ctags when creating a TAGS files in a directory
755 without files to scan but with subdirectories to include.
757 * Bugs introduced by 1.8:
759 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
760 not defined in the same conditions as the _LDADD that uses it.
762 - Do not warn when JAVAROOT is overridden, this is legitimate.
766 * Long standing bugs:
768 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
769 or any of the other *dir variables contain a space.
771 Please note that Automake does not and cannot support spaces in
772 filenames that are involved during the build. This change affects
773 only installation paths, so that `make install' does not bomb out
774 in packages configured with
775 ./configure --prefix '/c/Program Files'
777 - Fix the depfiles output so it works with GNU sed (<4.1) even when
778 POSIXLY_CORRECT is set.
780 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
781 since Autoconf 2.54, which defines LIBOBJS itself.
783 - Fix a potential (but unlikely) race condition in parallel elisp
784 builds. (Introduced in 1.7.3.)
786 - Do not assume that users override _DEPENDENCIES in all conditions
787 where Automake will try to define them.
789 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
790 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
793 This fix also affects the $(mkdir_p) variable defined since
794 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
795 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
797 - Secure temporary directory creation in `make distcheck'. (PR/413)
799 - Do not generate two build rules for `parser.h' when the
800 parser appears in two different conditionals.
802 - Work around a Solaris 8 /bin/sh bug in the test for dependency
803 checking. Usually ./configure will not pick this shell; so this
804 fix only helps cases where the shell is forced to /bin/sh.
806 * Bugs introduced by 1.8:
808 - In some situations (hand-written `m4_include's), aclocal would
809 call the `File::Spec->rel2abs' method, which was only introduced
810 in Perl 5.6. This new version reestablish support Perl 5.005.
812 It is likely that the next major Automake releases will require at
813 least Perl 5.6. Consider upgrading your development environment
814 if you are still using the five-year-old Perl 5.005.
816 - Automake would sometimes fail to define rules for targets listed
817 in variables defined in multiple conditions. For instance on
823 it would define only the `a.$(OBJEXT): a.c' rule and omit the
824 `b.$(OBJEXT): b.c' rule.
826 * New sections in manual:
828 - Third-Party Makefiles: how to interface third party Makefiles.
829 - Upgrading: upgrading packages to newer Automake versions.
830 - Multiple Outputs: handling tools that produce many outputs.
834 * A (well known) portability bug slipped in the changes made to
835 install-sh in Automake 1.8.1. The broken install-sh would refuse to
836 install anything on Tru64.
838 * Fix install rules for conditionally built python files. (This never
843 * Bugs introduced by 1.8:
845 - Fix Config.pm import error with old Perl versions (at least
846 5.005_03). One symptom is that aclocal could not find its macro
849 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
850 created by `make install' are always world readable, even if the
851 installer happens to have an overly restrictive umask (e.g. 077).
852 This was a mistake and has been reverted. There are at least two
853 reasons why we must not use `-m 0755':
854 - it causes special bits like SGID to be ignored,
855 - it may be too restrictive (some setups expect 775 directories).
857 - Fix aclocal to honor definitions located in files which have been
858 m4_included manually. aclocal 1.8 had been updated to check
859 m4_included files for new requirements, but forgot that these
860 m4_included files can also provide new definitions.
862 Note that if you have such a setup, we recommend you get rid of
863 it. In the past, there was a reason to m4_include files manually:
864 aclocal used to duplicate entire M4 files into aclocal.m4, even
865 files that were distributed. Some packages were therefore
866 m4_including the distributed file directly, and playing some
867 tricks to ensure aclocal would not copy that file to aclocal.m4,
868 in order to limit the amount of duplication. Since aclocal 1.8.x
869 will precisely output m4_includes for local M4 files, we recommend
870 that you clean up your setup, removing all manual m4_includes and
871 letting aclocal output them.
873 - Output detailed menus in the Info version if the Automake manual,
874 so that Emacs can locate the indexes.
876 - configure.ac and configure were listed twice in DIST_COMMON (an
877 internal variable where Automake lists configury files to
878 distribute). This was harmless, but unaesthetic.
880 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
881 This was an issue only in the Automake package itself, not in
884 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
885 DEST:SRC. This was wrong, as some packages do
886 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
889 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
890 argument. This caused two kinds of failures:
891 - Rules installing data in a conditionally defined directory
892 failed when that directory was undefined. In this case no
893 argument was supplied.
894 - `make installdirs' failed, because several directories were
895 passed to $(mkdir_p). This was an issue only on platform
896 were $(mkdir_p) is implemented with `install-sh -d'.
897 $(mkdir_p) as been changed to accept 0 or more arguments, as
900 * Long-standing bugs:
902 - Fix an unexpected diagnostic occurring when users attempt
903 to override some internal variables that Automake appends to.
905 - aclocal now scans configure.ac for macro definitions (PR/319).
907 - Fix a portability issue with OSF1/Tru64 Make. If a directory
908 distributes files which are outside itself (this usually occurs
909 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
910 from a parent package), then `make distcheck' fails due to an
911 optimization performed by OSF1/Tru64 Make in its VPATH handling.
912 (tests/subpkg2.test failure)
914 - Fix another portability issue with Sun and OSF1/Tru64 Make.
915 In a VPATH-build configuration, `make install' would install
916 nobase_ files to wrong locations.
918 - Fix a Perl `uninitialized value' diagnostic occurring when
919 automake complains that a Texinfo file does not have a
920 @setfilename statement.
922 - Erase config.status.lineno during `make distclean'. This file
923 can be created by config.status. Automake already knew about
924 configure.lineno, but forgot config.status.lineno.
926 - Distribute all files, even those which are built and installed
927 conditionally. This change affects files listed in conditionally
928 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
929 as well as those listed in conditionally defined dist_*_DATA,
930 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
932 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
933 doesn't conform to POSIX.
935 - Normalize help strings for configure variables and options added
940 - Check for python2.4 in AM_PATH_PYTHON.
942 * Spurious failures in test suite:
944 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
945 tests/ltconv.test: fix failures with CVS Libtool.
946 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
947 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
948 fix failures with old Texinfo versions.
954 - The NEWS file is more verbose.
958 - Autoconf 2.58 or greater is required.
962 - Default source file names in the absence of a _SOURCES declaration
963 are made by removing any target extension before appending `.c', so
964 to make the libtool module `foo.la' from `foo.c', you only need to
967 lib_LTLIBRARIES = foo.la
968 foo_la_LDFLAGS = -module
970 For backward compatibility, foo_la.c will be used instead of
971 foo.c if this file exists or is the explicit target of a rule.
972 However -Wobsolete will warn about this deprecated naming.
974 - AR's `cru' flags are now set in a global ARFLAGS variable instead
975 of being hard-coded in each $(AR) invocation, so they can be
976 substituted from configure.ac. This has been requested by people
977 dealing with non-POSIX ar implementations.
979 - New warning option: -Woverride. This will warn about any user
980 target or variable definitions which override Automake
983 - Texinfo rules back up and restore info files when makeinfo fails.
985 - Texinfo rules now support the `html' target.
986 Running this requires Texinfo 4.0 or greater.
988 `html' is a new recursive target, so if your package mixes
989 hand-crafted `Makefile.in's with Automake-generated
990 `Makefile.in's, you should adjust the former to support (or
991 ignore) this target so that `make html' recurses successfully. If
992 you had a custom `html' rule in your `Makefile.am', it's better to
993 rename it as `html-local', otherwise your rule will override
994 Automake's new rule (you can check that by running `automake
995 -Woverride') and that will stop the recursion to subdirectories.
997 Last but not least, this `html' rule is declared PHONY, even when
998 overridden. Fortunately, it appears that few packages use a
999 non-PHONY `html' rule.
1001 - Any file which is m4_included from configure.ac will appear as a
1002 configure and Makefile.in dependency, and will be automatically
1005 - The rules for rebuilding Makefiles and Makefile.ins will now
1006 rebuild all Makefiles and all Makefile.ins at once when one of
1007 configure's dependencies has changed. This is considerably faster
1008 than previous implementations, where config.status and automake
1009 were run separately in each directory (this still happens when you
1010 change a Makefile.am locally, without touching configure.ac or
1011 friends). Doing this also solves a longstanding issue: these
1012 rebuild rules failed to work when adding new directories to the
1013 tree, forcing you to run automake manually.
1015 - For similar reasons, the rules to rebuild configure,
1016 config.status, and aclocal.m4 are now defined in all directories.
1017 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1018 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1019 should better define them in all directories. This is easily done
1020 using an AC_SUBST (make sure you prefix these dependencies with
1021 $(top_srcdir) since this variable will appear at different
1022 levels of the build tree).
1024 - aclocal will now use `m4_include' instead of copying local m4
1025 files into aclocal.m4. (Local m4 files are those you ship with
1026 your project, other files will be copied as usual.)
1028 Because m4_included files are automatically distributed, it means
1029 for most projects there is no point in EXTRA_DISTing the list of
1030 m4 files which are used. (You can probably get rid of
1031 m4/Makefile.am if you had one.)
1033 - aclocal will avoid touching aclocal.m4 when possible, so that
1034 Autom4te's cache isn't needlessly invalidated. This behavior can
1035 be switched off with the new `--force' option.
1037 - aclocal now uses Autoconf's --trace to detect macros which are
1038 actually used and will no longer include unused macros simply
1039 because they where mentioned. This was often the case for macros
1040 called conditionally.
1042 - New options no-dist and no-dist-gzip.
1044 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1045 py-compile, and ylwrap, now all understand --version and --help.
1047 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1048 links as part of the distclean target and including source files in
1051 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1052 argument. The latter can be used to override the default behavior
1053 (which is to abort).
1055 - Automake will exit with $? = 63 on version mismatch. (So does
1056 Autoconf 2.58) missing knows this, and in this case it will
1057 emulate the tools as if they were absent. Because older versions
1058 of Automake and Autoconf did not use this exit code, this change
1059 will only be useful in projects generated with future versions of
1062 - When using AC_CONFIG_FILES with multiple input files, Automake
1063 generates the first ".in" input file for which a ".am" exists.
1064 (Former versions would try to use only the first input file.)
1066 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1067 idiom to disable byte-compilation of lisp_LISP files, it is
1068 recommended that you switch to using lisp_DATA. Note that
1069 this is not strictly equivalent: lisp_DATA will install elisp
1070 files even if emacs is not installed, while *_LISP do not
1071 install anything unless emacs is found.
1073 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1074 available. This selection is achieved through the Makefile
1075 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1076 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1077 `$(install_sh) -m 0755 -d'.
1081 - Because `mkdir -p' is available on most platforms, and we can use
1082 `install-sh -d' when it is not, the use of the mkinstalldirs
1083 script is being phased out. `automake --add-missing' no longer
1084 installs it, and if you remove mkinstalldirs from your package,
1085 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1087 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1088 gettextize and autopoint will install it when needed. Automake
1089 will continue to define the $(mkinstalldirs) and to distribute
1090 mkinstalldirs when this script is in the source tree.
1092 - AM_PROG_CC_STDC is now empty. The content of this macro was
1093 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1094 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1095 renaming should be safe, even if you have to support several,
1096 versions of Automake, because AC_PROG_CC defines this variable
1097 since Autoconf 2.54.)
1099 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1100 variable to override the aclocal.m4 dependencies computed
1101 (inaccurately) by older versions of Automake. Because Automake
1102 now tracks configure's m4 dependencies accurately (see m4_include
1103 above), the use of ACLOCAL_M4_SOURCES should be considered
1104 obsolete and will be flagged as such when running `automake
1109 - Defining programs conditionally using Automake conditionals no
1110 longer leads to a combinatorial explosion. The following
1111 construct used to be troublesome when used with dozens of
1126 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1128 - Due to implementation constraints, previous versions of Automake
1129 proscribed multiple conditional definitions of some variables
1139 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1140 This restriction has been lifted, and these variables now
1141 support multiple conditional definitions as do other variables.
1143 - Cleanup the definitions of $(distdir) and $(top_distdir).
1144 $(top_distdir) now points to the root of the distribution
1145 directory created during `make dist', as it did in Automake 1.4,
1146 not to the root of the build tree as it did in intervening
1147 versions. Furthermore these two variables are now only defined in
1148 the top level Makefile, and passed to sub-directories when running
1151 - The --no-force option now correctly checks the Makefile.in's
1152 dependencies before deciding not to update it.
1154 - Do not assume that make files are called Makefile in cleaning rules.
1156 - Update .info files in the source tree, not in the build tree. This
1157 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1158 used to update these files in the build tree (previous versions did
1159 it in the source tree too), and it caused several problems, varying
1160 from mere annoyance to portability issues.
1162 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1163 when --add-missing and --force-missing are used. For backward
1164 compatibility --add-missing will continue to install COPYING (in
1165 `gnu' strictness) when none of these three files exist, but this
1166 use is deprecated: you should better choose a license yourself and
1167 install it once for all in your source tree (and in your code
1170 - Fix ylwrap so that it does not overwrite header files that haven't
1171 changed, as the inline rule already does.
1173 - User-defined rules override automake-defined rules for the same
1174 targets, even when rules do not have commands. This is not new
1175 (and was documented), however some of the automake-generated
1176 rules have escaped this principle in former Automake versions.
1177 Rules for the following targets are affected by this fix:
1179 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1180 info, info-am, install-data-am, install-exec-am, install-info,
1181 install-info-am, install-man, installcheck-am, maintainer-clean,
1182 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1183 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1185 Practically it means that an attempt to supplement the dependencies
1186 of some target, as in
1188 clean: my-clean-rule
1190 will now *silently override* the automake definition of the
1191 rule for this target. Running `automake -Woverride' will diagnose
1192 all such overriding definitions.
1194 It should be noted that almost all these targets support a *-local
1195 variant that is meant to supplement the automake-defined rule
1196 (See node `Extending' in the manual). The above rule should
1199 clean-local: my-clean-rule
1201 These *-local targets have been documented since at least
1202 Automake 1.2, so you should not fear the change if you have
1203 to support multiple automake versions.
1207 - The Automake manual is now distributed under the terms of the GNU FDL.
1209 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1211 - core dumps are no longer removed by the cleaning rules. There are
1212 at least three reasons for this:
1213 1. These files should not be created by any build step,
1214 so their removal do not fit any of the cleaning rules.
1215 Actually, they may be precious to the developer.
1216 2. If such file is created during a build, then it's clearly a
1217 bug Automake should not hide. Not removing the file will
1218 cause `make distcheck' to complain about its presence.
1219 3. Operating systems have different naming conventions for
1220 core dump files. A core file on one system might be a
1221 completely legitimate data file on another system.
1223 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1224 defined by Automake. This means that any definition in the
1225 environment will be used, unless overridden in the Makefile.am or
1226 on the command line. The old behavior, where these variables were
1227 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1228 AC_ARG_VARing each variable from configure.ac.
1230 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1231 documented. (The is not a new feature, these variables have
1232 been there since at least Automake 1.4.)
1234 Bugs fixed in 1.7.9:
1235 * Fix install-strip to work with nobase_ binaries.
1236 * Fix renaming of #line directives in ylwrap.
1237 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1239 Bugs fixed in 1.7.8:
1240 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1241 * Fix detection of Debian's install-info, broken since version 1.5.
1242 (Debian bug #213524).
1243 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1244 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1246 Bugs fixed in 1.7.7:
1247 * The implementation of automake's --no-force option is unreliable,
1248 so this option is ignored in this version. A real fix will appear in
1249 Automake 1.8. (Debian Bug #206299)
1250 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1251 argument is given. (PR/399)
1252 * Do not warn about leading `_' in variable names, even with -Wportability.
1253 * Support user redefinitions of TEXINFO_TEX.
1254 * depcomp: support AIX Compiler version 6.
1255 * Fix missing rebuilds during `make dist' with BSD make.
1256 (Could produce tarballs containing out-of-date files.)
1257 * Resurrect multilib support.
1258 * Noteworthy manual updates:
1259 - Extending aclocal: how to write m4 macros that won't trigger warnings
1261 - A Shared Library: Rewrite and split into subsections.
1263 Bugs fixed in 1.7.6:
1264 * Fix depcomp's icc mode for ICC 7.1.
1265 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1266 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1267 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1268 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1269 * Remove Latin-1 characters from elisp-comp.
1270 * Update the manual's @dircategory to match the Free Software Directory.
1272 Bugs fixed in 1.7.5:
1273 * Update install-sh's license to remove an advertising clause.
1274 (Debian bug #191717)
1275 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1276 that caused invalid Makefile.ins to be generated.
1277 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1278 * New FAQ entry: renamed objects.
1280 Bugs fixed in 1.7.4:
1281 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1282 the Emacs implementation)
1283 * Fix output of aclocal.m4 dependencies in subdirectories.
1284 * Use `mv -f' instead of `mv' in fastdep rules.
1285 * Upgrade mdate-sh to work on OS/2.

1297 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1298 * Query distutils for `pythondir' and `pythonexecdir', instead of
1299 using an hardcoded path. This should allow builds on 64-bit
1300 distributions that usually use lib64/ instead of lib/.
1301 * AM_PATH_PYTHON will also search for python2.3.
1302 * elisp files are now built all at once instead of one by one. Besides
1303 incurring a speed-up, this is required to support interdependent elisp files.
1304 * Support for DJGPP:
1305 - `make distcheck' will now work in `_inst/' and `_build' instead
1306 of `=inst/' and `=build/'
1307 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1308 - install/uninstall `*.i[0-9][0-9]'-style info files
1309 - more changes that affect only the Automake package (not its output)
1310 * Fix some incompatibilities with upcoming perl-5.10.
1311 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1312 PACKAGE and VERSION.
1314 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1315 is troublesome with gcc and Solaris compilers. (PR/385)
1316 - makedepend mode: work with Libtool. (PR/385 too)
1318 * better support for unusual gettext setups, such as multiple po/ directories
1320 - Flag missing po/ and intl/ directories as warnings, not errors.
1321 - Disable these warnings if po/ does not exist.
1322 * Noteworthy manual updates:
1324 - Document how AC_CONFIG_AUX_DIR interacts with missing files.

1329 * Fix installation and uninstallation of Info files built in subdirectories.
1330 * Do not run `./configure --with-included-gettext' during `make distcheck'
1331 if AM_GNU_GETTEXT([external]) is used.
1332 * Correctly uninstall renamed man pages.
1333 * Do not strip escaped newline in variables defined in one condition
1334 and augmented in another condition.
1335 * Fix ansi2knr rules for LIBOBJS sources.
1336 * Clean all known Texinfo index files, not only those which appear to
1337 be used, because we cannot know wich indexes are used in included files.
1338 (PR/375, Debian Bug #168671)
1339 * Honor only the first @setfilename seen in a Texinfo file.
1340 * Treat "required file X not found" diagnostics as errors (exit status 1).
1341 * Don't complain that a required file is not found when it is a Makefile
1343 * Don't use single suffix inference rules when building `.info'-less
1344 Info files, for the sake of Solaris make.
1345 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1346 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1347 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1348 * Fix building of deansified files from subdirectories. (PR/370)
1349 * Add missing `fi' in the .c->.obj rules.
1350 * Improve install-sh to work even when names contain spaces or certain
1351 (but not all) shell metachars.
1352 * Fix the following spurious failures in the test suite:
1353 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1354 * Noteworthy manual updates:
1355 - Augment the section about BUILT_SOURCES.
1356 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1358 Bugs fixed in 1.7.1:
1359 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1361 * Aclocal should now recognize macro names containing parentheses, e.g.
1362 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1363 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1365 * Install Python files even if they were built. (PR/369)
1366 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1367 version might not be defined in the latter. (PR/358)
1368 * Reorder arguments passed to a couple of commands, so things works
1369 when POSIXLY_CORRECT=1.
1370 * Fix a regex that can cause Perl to segfault on large input.
1372 * Fix distribution of packages that have some sources defined conditionally,
1373 as in the `Conditional compilation using Automake conditionals' example
1375 * Fix spurious test suite failures on IRIX.
1376 * Don't report a required variable as undefined if it has been
1377 defined conditionally for the "right" conditions.
1378 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1379 `make distcheck' fails.
1380 * Fix distribution of included Makefile fragment, so we don't create
1381 spurious directories in the distribution. (PR/366)
1382 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1385 * Autoconf 2.54 is required.
1386 * `aclocal' and `automake' will no longer warn about obsolete
1387 configure macros. This is done by `autoconf -Wobsolete'.
1388 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1389 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1390 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1391 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1392 `configure.ac' for you.
1393 * Support for per-program and per-library `_CPPFLAGS'.
1394 * New `ctags' target (builds CTAGS files).
1395 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1396 (see `automake --help' or the manual for a list of them).
1397 * Honor the WARNINGS environment variable.
1398 * Omit the call to depcomp when using gcc3: call the compiler directly.
1399 * A new option, std-options, tests that programs support --help and --version
1400 when `make installcheck' is run. This is enabled by --gnits.
1401 * Texinfo rules now support the `ps' and `pdf' targets.
1402 * Info files are now created in the build directory, not the source directory.
1403 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1405 * `make distcheck' will enforce DESTDIR support by attempting
1407 * `+=' can be used in conditionals, even if the augmented variable
1408 was defined for another condition.
1409 * Makefile fragments (inserted with `include') are always distributed.
1410 * Use Autoconf's --trace interface to inspect configure.ac and get
1411 a more accurate view of it.
1412 * Add support for extending aclocal's default macro search path
1413 using a `dirlist' file within the aclocal directory.
1414 * automake --output-dir is deprecated.
1415 * The part of the distcheck target that checks whether uninstall actually
1416 removes all installed files has been moved in a separate target,
1417 distuninstallcheck, so it can be overridden easily.
1421 * Support for AM_INIT_GETTEXT([external])
1422 * Bug fixes, including:
1423 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1424 - nobase_ programs and scripts honor --program-transform correctly.
1425 - Erase configure.lineno during `make distclean'.

1441 - Don't choke on AM_LDFLAGS definitions.
1442 - Clean libtool objects from subdirectories.
1443 - Allow configure variables with reserved suffix and unknown prefix
1444 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1445 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1448 * Autoconf 2.52 is required.
1449 * automake no longer run libtoolize.
1450 This is the job of autoreconf (from GNU Autoconf).
1451 * `dist' generates all the archive flavors, as did `dist-all'.
1452 * `dist-gzip' generates the Gzip tar file only.
1453 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1454 explosion. Makefile.in's keep a reasonable size.
1455 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1456 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1458 * `#line' of Lex and Yacc files are properly set.
1459 * EXTRA_DIST can contain generated directories.
1460 * Support for dot-less extensions in suffix rules.
1461 * The part of the distcheck target that checks whether distclean actually
1462 cleans all built files has been moved in a separate target, distcleancheck,
1463 so it can be overridden easily.
1464 * `make distcheck' will pass additional options defined in
1465 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1466 * Fixed CDPATH portability problems, in particular for MacOS X.
1467 * Fixed handling of nobase_ targets.
1468 * Fixed support of implicit rules leading to .lo objects.

1471 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1472 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1473 (Note that "pkgname" is not "tarname", see the manual for details.)
1474 It is also possible to pass a list of global Automake options as
1475 first argument to this new form of AM_INIT_AUTOMAKE.
1476 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1477 to be a real assembler.
1478 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1479 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
