The Autoconf team -- Akim, Alexandre, Jim, Paul, and Tom -- is happy to annonce the birth of Autoconf 2.55. Download, compile, install, torture, and enjoy!
- Why should I upgrade from 2.54? A few bug fixes, improved portability, no known incompatibility with 2.54 and 2.55, forthcoming Gettext release might require 2.55. Running `autoreconf -fv' should be enough. - Why should I upgrade from 2.13? This version is no longer maintained. It does not address recent architectures, recent compilers etc. We know that upgrading from 2.13 to 2.5x is not an easy task, especially because the Autoconf 2.13 was extremely tolerant to incorrect macro invocations, but waiting longer endangers the portability of your package and only delays the conversation to newer Autoconf versions. Worse: some maintainers now spend a significant amount of time fixing bugs in 2.13 or backporting macros from 2.55. - Where can I find it? ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.55.tar.gz (1.1 MB) ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.55.tar.bz2 (794 KB) ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.54-2.55.delta (70 KB) and soon from the mirrors listed on http://www.gnu.org/order/ftp.html. Here are the MD5 and SHA1 signatures: d3e8ad97aa69853778125177967ed573 autoconf-2.55.tar.gz 4517bb0669b949935967f31329a29c0c autoconf-2.55.tar.bz2 c991edb76acbf686bed4ce1cb7a35cc2 autoconf-2.54-2.55.xdelta 69554487aec8606a17c53db2c7c7964be7138946 autoconf-2.55.tar.gz d6d7cf9a2df8736c2930d1e6104de9c7a8ccbaff autoconf-2.55.tar.bz2 717df2957e85ad4de9c3c651a5b3eff1b01e3857 autoconf-2.54-2.55.xdelta NEWS: Release tips: Have your configure.ac checked by autoscan ("autoscan"). Try the warning options ("autoreconf -fv -Wall"). ** Documentation - AC_CHECK_HEADER, AC_CHECK_HEADERS More information on proper use. - Writing Test Programs This sections explains how to write good test sources to use with AC_COMPILE_IFELSE etc. It documents AC_LANG_PROGRAMS and so forth. - AC_FOO_IFELSE vs. AC_TRY_FOO Explains why Autoconf moves from AC_TRY_COMPILE etc. to AC_COMPILE_IFELSE and AC_LANG_PROGRAM etc. ** autoreconf - Is more robust to different Gettext installations. - Produces messages (when --verbose) to be understood by Emacs' compile mode. - Supports -W/--warnings. - -m/--make Once the GNU Build System reinstalled, run `./config.status --recheck && ./config.status && make' if possible. ** autom4te - Supports --cache, and --no-cache. - ~/.autom4te.cfg makes it possible to disable the caching mechanism (autom4te.cache). See `Customizing autom4te' in the documentation. ** Obsolete options Support for the obsoleted options -m, --macrodir, -l, --localdir is dropped in favor of the safer --include/--prepend-include scheme. ** Macros - New macros AC_COMPILER_IFELSE, AC_FUNC_MBRTOWC, AC_HEADER_STDBOOL, AC_LANG_CONFTEST, AC_LANG_SOURCE, AC_LANG_PROGRAM, AC_LANG_CALL, AC_LANG_FUNC_TRY_LINK, AC_MSG_FAILURE, AC_PREPROC_IFELSE. - Obsoleted Obsoleted macros are kept for Autoconf backward compatibility, but should be avoided in configure.ac. Running autoupdate is advised. AC_DECL_SYS_SIGLIST. ** Bug Fixes - Portability of the Autoconf package to Solaris. - Spurious warnings caused by config.status. This bug is benign, but painful: on some systems (typically FreeBSD), warnings such as: config.status: creating Makefile mv: Makefile: set owner/group (was: 1357/0): Operation not permitted could be issued. This is fixed. - Parallel Builds Simultaneous executions of config.status are possible again. - Precious variables accumulation config.status could stack several copies of the precious variables assignments. ** Plans for 2.56 - ./configure <host> The compatibility hooks with the old scheme will be completely removed. Please, advice/use `--build', `--host', and `--target' only. - AC_CHECK_HEADER, AC_CHECK_HEADERS The tests will be stricter, please make sure your invocations are valid. - shell functions Shell functions will gradually be introduced, probably starting with Autotest. If you know machines which are in use that you suspect *not* to support shell functions, please run the test suite of Autoconf 2.55 on it, and report the results to [EMAIL PROTECTED]
