We're pleased to announce the release of Automake 1.11.
Automake is a tool for automatically generating `Makefile.in's
suitable for use with Autoconf, compliant with the GNU Makefile
standards, and portable to various make implementations.
This release contains a bunch of new features and a bunch of bug fixes
over previous versions. Highlights over 1.10, in no particular order:
Optional Linux kernel style less verbose compile rules, faster rules for
(un)install, support for parallel tests, colored tests output, improved
Fortran and initial Vala support, threaded automake execution, lzma/xz
compressed tarballs, man pages which are not transformed, non-".c"
default sources, better AM_MAINTAINER_MODE, man pages for aclocal and
automake. See the NEWS excerpt below for more details, and a couple of
things to note when upgrading.
The important changes of 1.11 over the last test release, 1.10b, are
documented here:
<http://git.savannah.gnu.org/cgit/automake.git/tree/NEWS?id=7fa2890c4ec91ae20589eee67eef0be9bcbe159b>
Further, the test release was released using GPLv3+, but the 1.11
release uses GPLv2+. Automake will again move to GPLv3+ once the
Exception has been rewritten to use the new GPL Exception language.
A big thanks to all people who have been testing pre-release, reporting
bugs, contributing code, suggesting enhancements, and answering user
questions on the mailing lists!

New in 1.11:
* Version requirements:
- Autoconf 2.62 or greater is required.
* Changes to aclocal:
- The autoconf version check implemented by aclocal in aclocal.m4
(and new in Automake 1.10) is degraded to a warning. This helps
in the common case where the Autoconf versions used are compatible.
* Changes to automake:
- The automake program can run multiple threads for creating most
Makefile.in files concurrently, if at least Perl 5.7.2 is available
with interpreter-based threads enabled. Set the environment variable
AUTOMAKE_JOBS to the maximum number of threads to use, in order to
enable this experimental feature.
* Changes to Libtool support:
- Libtool generic flags are now passed to the install and uninstall
modes as well.
- distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
config.lt is removed correctly now.
* Languages changes:
- subdir-object mode works now with Fortran (F77, FC, preprocessed
Fortran, and Ratfor).
- For files with extension .f90, .f95, .f03, or .f08, the flag
$(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
- Files with extension .sx are also treated as preprocessed assembler.
- The default source file extension (.c) can be overridden with
AM_DEFAULT_SOURCE_EXT now.
- Python 3.0 is supported now, Python releases prior to 2.0 are no
longer supported.
- AM_PATH_PYTHON honors python's idea about the site directory.
- There is initial support for the Vala programming language, when using
Vala 0.7.0 or later.
* Miscellaneous changes:
- Automake development is done in a git repository on Savannah now, see
http://git.sv.gnu.org/gitweb/?p=automake.git
A read-only CVS mirror is provided at
cvs -d :pserver:anonymous at pserver.git.sv.gnu.org:/automake.git \
checkout -d automake HEAD
- "make dist" can now create xz-compressed tarballs,
as well as (deprecated?) lzma-compressed tarballs.
- `automake --add-missing' will by default install the GPLv3 file as
COPYING if it is missing. It will also warn that the license file
should be added to source control. Note that Automake will never
overwrite an existing COPYING file, even when the `--force-missing'
option is used.
- The manual is now distributed under the terms of the GNU FDL 1.3.
- Automake ships and installs man pages for automake and aclocal now.
- New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
- install-sh supports -C, which does not update the installed file
(and its time stamps) if the contents did not change.
- The `gnupload' script has been revamped.
- The `depcomp' and `compile' scripts now work with MSVC under MSYS.
- The targets `install' and `uninstall' are more efficient now, in that
for example multiple files from one Automake variable such as
`bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
invocation if they do not have to be renamed.
Both install and uninstall may sometimes enter (`cd' into) the target
installation directory now, when no build-local scripts are used.
Both install and uninstall do not fail anymore but do nothing if an
installation directory variable like `bindir' is set to the empty string.
For built-in rules, `make install' now fails reliably if installation
of a file failed. Conversely, `make uninstall' even succeeds when
issued multiple times.
These changes may need some adjustments from users: For example,
some `install' programs refuse to install multiple copies of the
same file in one invocation, so you may need to remove duplicate
entries from file lists.
Also, within one set of files, say, nobase_data_DATA, the order of
installation may be changed, or even unstable among different hosts,
due to the use of associative arrays in awk. The increased use of
awk matches a similar move in Autoconf to provide for better scaling.
Further, most undocumented per-rule install command variables such as
binSCRIPT_INSTALL have been removed because they are not needed any
more. Packages which use them should be using the appropriate one of
INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
counterpart, depending on the type of files and the need for automatic
target directory creation.
- The "deleted header file problem" for *.m4 files is avoided by
stub rules. This allows `make' to trigger a rerun of `aclocal'
also if some previously needed macro file has been removed.
- Rebuild rules now also work for a removed `subdir/Makefile.in' in
an otherwise up to date tree.
- The `color-tests' option causes colored test result output on terminals.
- The `parallel-tests' option enables a new test driver that allows for
parallel test execution, inter-test dependencies, lazy test execution
for unit-testing, re-testing only failed tests, and formatted result output
as RST (reStructuredText) and HTML. Enabling this option may require some
changes to your test suite setup; see the manual for details.
- The `silent-rules' option enables Linux kernel-style silent build output.
This option requires the widely supported but non-POSIX `make' feature
of recursive variable expansion, so do not use it if your package needs
to build with `make' implementations that do not support it.
To enable less verbose build output, the developer has to use the Automake
option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
macro. The user may then set the default verbosity by passing the
`--enable-silent-rules' option to `configure'. At `make' run time, this
default may be overridden using `make V=0' for less verbose, and `make V=1'
for backward-compatible verbose output.
- New prefix `notrans_' for manpages which should not be transformed
by --program-transform.
- New macro AM_COND_IF for conditional evaluation and conditional
config files.
- For AC_CONFIG_LINKS, if source and destination are equal, do not
remove the file in a non-VPATH build. Such setups work with Autoconf
2.62 or newer.
- AM_MAINTAINER_MODE now allows for an optional argument specifying
the default setting.
- AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
useful especially for multi-line values.
- Automake's early configure-time sanity check now diagnoses an
unsafe absolute source directory name and makes configure fail.
- The Automake macros and rules cope better with whitespace in the
current directory name, as long as the relative path to `configure'
does not contain whitespace. To this end, the values of `$(MISSING)'
and `$(install_sh)' may contain suitable quoting, and their expansion
might need `eval'uation if used outside of a makefile. These
undocumented variables may be used in several documented macros such
as $(AUTOCONF) or $(MAKEINFO).
Bugs fixed in 1.11:
* Long standing bugs:
- Fix aix dependency tracking for libtool objects.
- Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
unnecessary use of the `compile' script.
- For nobase_*_LTLIBRARIES with nonempty directory components, the
correct `-rpath' argument is used now.
- `config.status --file=Makefile depfiles' now also works with the
extra quoting used internally by Autoconf 2.62 and newer
(it used to work only without the `--file=' bit).
- The `missing' script works better with versioned tool names.
- Semantics for `missing help2man' have been revamped:
Previously, if `help2man' was not present, `missing help2man' would have
the following semantics: if some man page was out of date but present, then
a warning would be printed, but the exit status was 0. If the man page was
not present at all, then `missing' would create a replacement man page
containing an error message, and exit with a status of 2. This does not play
well with `make': the next run will see this particular man page as being up
to date, and will only error out on the next generated man page, if any;
repeat until all pages are done. This was not desirable.
These are the new semantics: if some man page is not present, and help2man
is not either, then `missing' will warn and generate the replacement page
containing the error message, but exit successfully. However, `make dist'
will ensure that no such bogus man pages are packaged into a tarball.
- Targets provided by automake behave better with `make -n', in that they
take care not to create files.
- `config.status Makefile... depfiles' works fine again in the presence of
disabled dependency tracking.
- The default no-op recursive rules for these targets also work with BSD make
now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
- `make distcheck' works also when both a directory and some file below it
have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
- Texinfo dvi, ps, pdf, and html output files are not removed upon
`make mostlyclean' any more; only the LaTeX by-products are.
- Renamed objects also work with the `subdir-objects' option and
source file languages which Automake does not know itself.
- `automake' now correctly complains about variable assignments which are
preceded by a comment, extend over multiple lines with backslash-escaped
newlines, and end in a comment sign. Previous versions would silently
and wrongly ignore such assignments completely.
* Bugs introduced by 1.10:
- Fix output of dummy dependency files in presence of post-processed
Makefile.in's again, but also cope with long lines.
- $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
that have been declared as programs in the same Makefile.
This is for consistency with the analogous change to TESTS in 1.10.
- Fix order of standard includes to again be `-I. -I$(srcdir)',
followed by directories containing config headers.
