Cc: various GNU mailing lists Subject: Autoconf 2.60 released We're happy to announce the release of Autoconf 2.60. Please grab it from one of the gnu.org mirror sites. The important changes since 2.59 are listed below. Two of these changes require special attention: * Some directory variables have been added, and others adjusted to changes in the GNU Coding Standards. If your package expands '$datadir', '$infodir', or '$mandir' anywhere, you need to check your package, and possibly adjust it accordingly. The nodes 'Changed Directory Variables' and 'Defining Directories' in the manual have more information; be sure to read them. * AC_PROG_CC and AC_PROG_CXX no longer arrange for an 'exit' function declaration. If you use this in your macros, you need to ensure that such a declaration is in place for C99 and C++ checks, or change the tests to 'return' from 'main' instead.

NEWS * Major changes in Autoconf 2.60 Released 2006-06-23, by Ralf Wildenhues. ** Autoconf no longer depends on whether m4wrap is FIFO (as Posix requires) or LIFO (as in GNU M4 1.4.x). GNU M4 2.0 is expected to conform to Posix here, so m4wrap/m4_wrap users should no longer depend on LIFO behavior. ** Provide a way to turn off warnings about the changed directory variables. * Major changes in Autoconf 2.59d Released 2006-06-05, by Ralf Wildenhues. ** GNU make now recommended for VPATH builds INSTALL now suggests VPATH builds (e.g., "sh ../srcdir/configure") only if you use GNU make. In practice, other 'make' implementations have too many subtle incompatibilities in their support for VPATH. Many packages (including Autoconf itself) are portable to other 'make' implementations, but some packages are not, and recommending GNU make keeps the installation instructions simpler. ** Even more safety checks for the new Directory variables: Warn about suspicious `${datarootdir}' found in config files output. ** AC_TRY_COMMAND, AC_TRY_EVAL, ac_config_guess, ac_config_sub, ac_configure These never-documented macros and variables have been marked with comments saying that they may be removed in a future release, because their use can lead to unintended code being executed. If you need functionality that only these macros or variables currently supply, please write bug-autoconf AT gnu DOT org. ** AC_SUBST, AC_DEFINE Literal arguments to these are passed to m4_pattern_allow now. ** AC_PROG_CC_STDC Passing 'ac_cv_prog_cc_stdc=no' to 'configure' now sets ac_cv_prog_cc_c99 and ac_cv_prog_cc_c89 to 'no' as well, for backward compatibility with obsolete K&R tests in the Automake test suite. ** AC_PROG_CXX_C_O New macro. ** AC_PROG_MKDIR_P New macro. ** AS_MKDIR_P Now more robust with special characters in file names, or when multiple processes create the same directory at the same time. ** Obsolescent macros The documentation now says that the following macros are obsolescent: they test for problems that are so old that they are no longer of practical importance on current systems. AC_C_BACKSLASH_A AC_FUNC_MEMCMP AC_HEADER_DIRENT AC_C_CONST AC_FUNC_SELECT_ARGTYPES AC_HEADER_STAT AC_C_PROTOTYPES AC_FUNC_SETPGRP AC_HEADER_STDC AC_C_STRINGIZE AC_FUNC_SETVBUF_REVERSED AC_HEADER_SYS_WAIT AC_C_VOLATILE AC_FUNC_STAT AC_HEADER_TIME AC_FUNC_CLOSEDIR_VOID AC_FUNC_STRFTIME AC_ISC_POSIX AC_FUNC_GETPGRP AC_FUNC_UTIME_NULL AC_PROG_GCC_TRADITIONAL AC_FUNC_LSTAT AC_FUNC_VPRINTF AC_STRUCT_TM New programs need not use these macros. We have no current plans to remove them. ** autoreconf For compatibility with future Libtool 2.0, autoreconf will invoke libtoolize with the option `--ltdl' now, if LT_CONFIG_LTDL_DIR is used. * Major changes in Autoconf 2.59c Released 2006-04-12, by Ralf Wildenhues. ** The configure command now redirects standard input from /dev/null, to help avoid problems with subsidiary commands that might mistakenly read standard input. AS_ORIGINAL_STDIN_FD points to the original standard input before this redirection, if you really want configure to read from standard input. ** Directory variables adjusted to recent changes in the GNU Coding Standards. The following directory variables are new: datarootdir read-only architecture-independent data root [PREFIX/share] localedir locale-specific message catalogs [DATAROOTDIR/locale] docdir documentation root [DATAROOTDIR/doc/PACKAGE] htmldir html documentation [DOCDIR] dvidir dvi documentation [DOCDIR] pdfdir pdf documentation [DOCDIR] psdir ps documentation [DOCDIR] The following variables have new default values: datadir read-only architecture-independent data [DATAROOTDIR] infodir info documentation [DATAROOTDIR/info] mandir man documentation [DATAROOTDIR/man] This means that if you use any of `@datadir@', `@infodir@', or `@mandir@' in a file, you will have to ensure `${datarootdir}' is defined in this file. As a temporary measure, if any of those are found but no mention of `datarootdir', the substitutions will be replaced with values that do not contain `${datarootdir}', and a warning will be issued. ** @top_builddir@ is now a dir name: it is always nonempty and doesn't have a trailing slash. Similar change will be made to ac_top_builddir in a future release; the old style value, which matches (../)*, is (and will continue to be) available as ac_top_build_prefix. ** AC_C_TYPEOF New macro to check for support of 'typeof' syntax a la GNU C. ** AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_HEADERS_ONCE New "once-only" variants of commonly-used macros, to make 'configure' smaller and faster in common cases. ** AC_FUNC_STRTOLD New macro to check for strtold with C99 semantics. ** AC_HEADER_ASSERT New macro that lets builder disable assertions at 'configure'-time. ** AC_PATH_X Now checks for X11/Xlib.h and XrmInitialize (X proper) rather than X11/Intrinsic.h and XtMalloc (Xt). ** AC_PRESERVE_HELP_ORDER New macro that causes `configure' to display help strings for AC_ARG_ENABLE and AC_ARG_WITH arguments in one region, in the order defined. The default behavior is to group options of each classes separately. ** AC_PROG_CC, AC_PROG_CXX No longer automatically arrange to declare the 'exit' function of C, when a C++ compiler is used. Standard Autoconf macros no longer use 'exit', so this is no longer an issue for them. If you use C++, and want to call 'exit', you'll have to arrange for its declaration yourself. But we now suggest you return from 'main' instead. ** AC_PROG_CC_C89, AC_PROG_CC_C99 New macros for ISO C99 support. AC_PROG_CC_C89 and AC_PROG_CC_C99 check for ANSI C89 and ISO C99 support respectively. ** AC_PROG_CC_STDC Has been unobsoleted, and will check if the compiler supports ISO C99, falling back to ANSI C89 if not. ac_cv_prog_cc_stdc is retained for backwards compatibility, assuming the value of ac_cv_prog_cc_c99 or ac_cv_prog_cc_c89 (whichever is valid, in that order). ** AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE New macros for checking commonly-used members of struct dirent. ** AC_SUBST The substituted value can now contain newlines. ** AC_SUBST_FILE The substitution now occurs only when @variable@ is on a line by itself, optionally surrounded by spaces and tabs. The whole line is replaced. ** AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER New macros to check for long double, and whether it is wider than double. The old macro AC_C_TYPE_LONG_DOUBLE has been marked as obsolete; applications should switch to the new macro. ** AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T, AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT, AC_TYPE_SSIZE_T, AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT New macros to check for C99 and POSIX types. ** AC_USE_SYSTEM_EXTENSIONS New macro to enable extensions to Posix. ** AH_HEADER New macro which is defined to the name of the first declared config header or undefined if no config headers have been declared yet. ** AS_HELP_STRING The macro correctly handles quadrigraphs now. ** AS_BOURNE_COMPATIBLE, AS_SHELL_SANITIZE, AS_CASE These macros are new or published now. ** AT_COPYRIGHT New macro for copyright notices in testsuite files. ** ALLOCA, LIBOBJS, LTLIBOBJS Object names added to these variables are now prefixed with `${LIBOBJDIR}', as in `${LIBOBJDIR}alloca.o'. LIBOBJDIR is meant to be defined from `Makefile.in' in case the object files lie in a different directory. The LIBOBJDIR feature is experimental. ** autoreconf Supports --no-recursive now. ** New macros to support Erlang/OTP. New macros for configuring paths to Erlang tools and libraries: AC_ERLANG_PATH_ERLC, AC_ERLANG_NEED_ERLC, AC_ERLANG_PATH_ERL, AC_ERLANG_NEED_ERL, AC_ERLANG_CHECK_LIB, AC_ERLANG_SUBST_ROOT_DIR, AC_ERLANG_SUBST_LIB_DIR. New macros for configuring installation of Erlang libraries: AC_ERLANG_SUBST_INSTALL_LIB_DIR, AC_ERLANG_SUBST_INSTALL_LIB_SUBDIR. ** The manual now mentions Gnulib more prominently. ** New macros to support Objective C. AC_PROG_OBJC, AC_PROG_OBJCPP. * Major changes in Autoconf 2.59b Released 2004-08-20, by Paul Eggert. ** AC_CHECK_ALIGNOF New macro that computes the default alignment of a type. ** AC_CHECK_TOOL, AC_PATH_TOOL, AC_CHECK_TOOLS When cross-compiling, these macros will give a warning if the tool is not prefixed. In the future, unprefixed cross tools will not be detected; please consult the info documentation for information about the reason of this change. ** AC_CHECK_TARGET_TOOL, AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOLS New macros that detect programs whose name is prefixed with the target type, if the build type and target type are different. ** AC_REQUIRE_AUX_FILE New trace macro that declares expected auxiliary files. ** AC_PROG_GREP New macro that tests for a grep program that accepts as a long a line as possible. ** AC_PROG_EGREP, AC_PROG_FGREP These macros now require AC_PROG_GREP, and try EGREP="$GREP -E" and FGREP="$GREP -F" respectively if possible, or else run a path search for a program that accepts as long a line as possible. ** AC_PROG_SED New macro that tests for a sed program that truncates as few characters as possible. Here is a link to the ChangeLog entries since 2.59: http://savannah.gnu.org/cgi-bin/viewcvs/autoconf/autoconf/ChangeLog.diff?r1= 1.2305&r2=1.2975&diff_format=u Configured, made (make), and made install into /usr/local/bin sucessfully under Cygwin. Unfortunately, the other versions of autoconf on Cygwin's setup.exe make a symlink to the latest autoconf in /usr/bin (/bin), and autoconf-2.60 does not. Therefore, this shell script will do everything I have just specified: echo 'I am getting autoconf-2.60 sources now.' cd /usr/src wget ftp://ftp.gnu.org/gnu/autoconf/autoconf-2.60.tar.bz2 tar xjvf autoconf-2.60.tar.bz2 cd autoconf-2.60 rm ../bin/autoconf rm ../bin/autoheader rm ../bin/autom4te rm ../bin/autoreconf rm ../bin/autoscan rm ../bin/autoupdate echo 'Now configuring for make. I am now going to run configure with a /usr prefix.' echo 'After this I am going to build autoconf-2.60.' ./configure --prefix='/usr'; make make install echo 'I am creating links to your newly compiled and installed autoconf-2.60.' cd ../bin link autoconf autoconf-2.60 link autoheader autoheader-2.60 link autom4te autom4te-2.60 link autoreconf autoreconf-2.60 link autoscan autoscan-2.60 link autoupdate autoupdate-2.60 echo 'Autoconf-2.60 has been set up and is ready to use. :-)' Note that make install's default behaviour is to install into /usr/local. Since we want to make autoconf-2.60 accessible to all users (if there is more than one user), and that setup.exe's older autoconf versions install into /usr, then we must set a prefix. Upload?
