We are pleased to announce the GNU Automake 1.15.1 maintenance release. This much-needed, bug-fixing release comes after a year and a half of stalling and inactivity in the Automake development. The main motivation for this release is to remove some warnings that were appearing due to the deprecation of features in Perl and gzip latest versions.
See below for the detailed list of changes since the previous version, as summarized by the NEWS file. Download here: ftp://ftp.gnu.org/gnu/automake/automake-1.15.1.tar.gz ftp://ftp.gnu.org/gnu/automake/automake-1.15.1.tar.xz Please report bugs and problems to <bug-autom...@gnu.org>, and send general comments and feedback to <automake@gnu.org>. Thanks to everyone who has reported problems, contributed patches, and helped testing Automake! -*-*-*- * WARNING: Future backward-incompatibilities! - Makefile recipes generated by Automake 2.0 will expect to use an 'rm' program that doesn't complain when called without any non-option argument if the '-f' option is given (so that commands like "rm -f" and "rm -rf" will act as a no-op, instead of raising usage errors). This behavior of 'rm' is very widespread in the wild, and it will be required in the next POSIX version: <http://austingroupbugs.net/view.php?id=542> Accordingly, AM_INIT_AUTOMAKE now expands some shell code that checks that the default 'rm' program in PATH satisfies this requirement, aborting the configure process if this is not the case. For the moment, it's still possible to force the configuration process to succeed even with a broken 'rm', that that will no longer be the case for Automake 2.0. - Automake 2.0 will require Autoconf 2.70 or later (which is still unreleased at the moment of writing, but is planned to be released before Automake 2.0 is). - Automake 2.0 will drop support for the long-deprecated 'configure.in' name for the Autoconf input file. You are advised to start using the recommended name 'configure.ac' instead, ASAP. - The ACLOCAL_AMFLAGS special make variable will be fully deprecated in Automake 2.0: it will raise warnings in the "obsolete" category (but still no hard error of course, for compatibilities with the many, many packages that still relies on that variable). You are advised to start relying on the new Automake support for AC_CONFIG_MACRO_DIRS instead (which was introduced in Automake 1.13). - Automake 2.0 will remove support for automatic dependency tracking with the SGI C/C++ compilers on IRIX. The SGI depmode has been reported broken "in the wild" already, and we don't think investing time in debugging and fixing is worthwhile, especially considering that SGI has last updated those compilers in 2006, and retired support for them in December 2013: <http://www.sgi.com/services/support/irix_mips_support.html> - Automake 2.0 will remove support for MS-DOS and Windows 95/98/ME (support for them was offered by relying on the DJGPP project). Note however that both Cygwin and MSYS/MinGW on modern Windows versions will continue to be fully supported. - Automake-provided scripts and makefile recipes might (finally!) start assuming a POSIX shell in Automake 2.0. There still is no certainty about this though: we'd first like to wait and see whether future Autoconf versions will be enhanced to guarantee that such a shell is always found and provided by the checks in ./configure. - Starting from Automake 2.0, third-party m4 files located in the system-wide aclocal directory, as well as in any directory listed in the ACLOCAL_PATH environment variable, will take precedence over "built-in" Automake macros. For example (assuming Automake is installed in the /usr/local hierarchy), a definition of the AM_PROG_VALAC macro found in '/usr/local/share/aclocal/my-vala.m4' should take precedence over the same-named automake-provided macro (defined in '/usr/local/share/aclocal-2.0/vala.m4'). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.15.1: * Bugs fixed: - The code has been adapted to remove a warning present since Perl 5.22 stating that "Unescaped left brace in regex is deprecated". This warning has become an hard error in Perl 5.26 (bug#22372). - The generated Makefiles do not rely on the obsolescent GZIP environment variable which was used for passing arguments to 'gzip'. Compatibility with old versions has been preserved. (bug#20132) * Miscellaneous changes: - Support the Windows version of the Intel C Compiler (icl) in the 'compile' script in the same way the (compatible) Microsoft C Compiler is supported. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
