AM_GNU_GETTEXT([external], [need-ngettext]) AM_GNU_GETTEXT_REQUIRE_VERSION([0.19]) dnl The following kludge is needed when using autoconf 2.69. dnl Observe the following: dnl 1. Autopoint (0.19.8.1) understands the AM_GNU_GETTEXT_REQUIRE_VERSION dnl macro, but autoreconf 2.69 reports: dnl configure.ac: AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION dnl and doesn't call autopoint at all. dnl 2. On the other hand, when both macros are used, autopoint warns: dnl using AM_GNU_GETTEXT_REQUIRE_VERSION instead of AM_GNU_GETTEXT_VERSION dnl (which it actually does). dnl dnl To make both happy, the following kludge is installed, which uses the fact dnl that autoreconf 2.69 looks for /^AM_GNU_GETTEXT_VERSION/ (see line 341), dnl and autopoint, when working with the file written for autoconf 2.69, uses a dnl simple sed logic to detect the presence of either macro. The kludge below dnl easily fools that logic. When working with autoconf 2.70 and later, dnl autopoint traces the m4 output, in which m4_if expands to nothing. dnl dnl When we finally switch to 2.70, this will be removed. dnl m4_if([ AM_GNU_GETTEXT_VERSION ]) AC_CHECK_HEADERS([sys/file.h string.h locale.h getopt.h]) AC_CHECK_FUNCS([ftruncate flock lockf fsync setlocale getopt_long]) if test x$mapped_io = xyes then AC_FUNC_MMAP() AC_CHECK_FUNCS([msync]) fi AC_TYPE_OFF_T AC_CHECK_SIZEOF(off_t) AC_CHECK_MEMBERS([struct stat.st_blksize, struct stat.st_mtim, struct stat.st_mtimespec],[],[], [#include #include ]) AM_CONDITIONAL([COMPAT_OPT], [test "$want_compat" = yes]) # Check for Curses libs. for lib in ncurses curses termcap do AC_CHECK_LIB($lib, tputs, [CURSES_LIBS="-l$lib"; break]) done AC_SUBST(CURSES_LIBS) # Readline AC_ARG_WITH([readline], AS_HELP_STRING([--without-readline], [do not use readline]), [ case "${withval}" in yes) status_readline=yes ;; no) status_readline=no ;; *) AC_MSG_ERROR(bad value ${withval} for --without-readline) ;; esac],[status_readline=probe]) AC_SUBST(READLINE_LIBS) if test "$status_readline" != "no"; then dnl FIXME This should only link in the curses libraries if it's dnl really needed! saved_LIBS=$LIBS LIBS="$LIBS $CURSES_LIBS" AC_CHECK_LIB(readline, readline, [status_readline=yes], [if test "$status_readline" = "yes"; then AC_MSG_ERROR(readline requested but does not seem to be installed) else status_readline=no fi]) LIBS=$saved_LIBS if test "$status_readline" = "yes"; then AC_CHECK_HEADERS(readline/readline.h, AC_DEFINE(WITH_READLINE,1,[Enable use of readline])) READLINE_LIBS="-lreadline $CURSES_LIBS" saved_LIBS=$LIBS LIBS="$LIBS $READLINE_LIBS" AC_CHECK_FUNCS(rl_completion_matches) LIBS=$saved_LIBS fi else status_readline=no fi AM_CONDITIONAL([GDBM_COND_READLINE], [test "$status_readline" = "yes"]) # CoW crash tolerance support AC_ARG_ENABLE([crash-tolerance], AS_HELP_STRING( [--enable-crash-tolerance], [Enable crash tolerance, based on clone/copy-on-write (needs support for FICLONE)]), [status_ficlone=$enableval], [status_ficlone=probe]) if test $status_ficlone = probe; then AC_CHECK_HEADER([linux/fs.h], [AC_MSG_CHECKING([for FICLONE ioctl support]) AC_COMPILE_IFELSE([AC_LANG_PROGRAM([ #include #include ], [ioctl(0, FICLONE, 1);])], [status_ficlone=yes], [status_ficlone=no]) AC_MSG_RESULT($status_ficlone)], [status_ficlone=no]) fi if test $status_ficlone = yes; then AC_DEFINE([GDBM_FAILURE_ATOMIC], 1, [Define if support for atomic failures is enabled]) fi # Additional debugging AC_ARG_ENABLE([debug], AS_HELP_STRING([--enable-debug], [provide additional debugging information]), [status_debug=$withval], [status_debug=no]) AC_SUBST([GDBM_DEBUG_ENABLE]) if test "$status_debug" = "yes"; then GDBM_DEBUG_ENABLE=1 else GDBM_DEBUG_ENABLE=0 fi AM_CONDITIONAL([GDBM_COND_DEBUG_ENABLE], [test "$status_debug" = "yes"]) AC_SUBST(YFLAGS_DEBUG) AC_SUBST(LFLAGS_DEBUG) if test "$want_gdbmtool_debug" = yes; then YFLAGS_DEBUG=-t LFLAGS_DEBUG=-d fi AM_CONDITIONAL([COND_GDBMTOOL_DEBUG], [test "$want_gdbmtool_debug" = yes]) # Initialize the test suite.
