2009-12-10 Stepan Kasal <skasal@redhat.com> The change of implementation of AC_REQUIRE in 2.64 caused a regression in the arts project. This can be fixed by shuffling some macro calls. I suppose that most of this patch will not be needed with a future release of Autoconf. But the last chunk of this patch is a real bug in this source and should go upstream. --- arts-1.5.10/admin/acinclude.m4.in 2008-08-20 18:07:05.000000000 +0200 +++ arts-1.5.10/admin/acinclude.m4.in 2009-12-09 17:30:57.000000000 +0100 @@ -3081,8 +3081,18 @@ fi ]) +AC_DEFUN([AC_CHECK_COMPILERS_CC], +[ + dnl this prevents stupid AC_PROG_CC to add "-g" to the default CFLAGS + CFLAGS=" $CFLAGS" + AC_PROG_CC + CXXFLAGS=" $CXXFLAGS" + AC_PROG_CXX +]) + AC_DEFUN([AC_CHECK_COMPILERS], [ + AC_REQUIRE([AC_CHECK_COMPILERS_CC]) AC_ARG_ENABLE(debug, AC_HELP_STRING([--enable-debug=ARG],[enables debug symbols (yes|no|full) [default=no]]), [ @@ -3141,11 +3151,6 @@ [kde_use_profiling="no"] ) - dnl this prevents stupid AC_PROG_CC to add "-g" to the default CFLAGS - CFLAGS=" $CFLAGS" - - AC_PROG_CC - AC_PROG_CPP if test "$GCC" = "yes"; then @@ -3174,10 +3179,6 @@ LDFLAGS="" fi - CXXFLAGS=" $CXXFLAGS" - - AC_PROG_CXX - KDE_CHECK_FOR_BAD_COMPILER if test "$GXX" = "yes" || test "$CXX" = "KCC"; then @@ -3503,8 +3504,8 @@ AC_REQUIRE([AC_LIBTOOL_DLOPEN]) AC_REQUIRE([KDE_CHECK_LIB64]) -AC_OBJEXT -AC_EXEEXT +AC_REQUIRE([AC_OBJEXT]) +AC_REQUIRE([AC_EXEEXT]) AM_PROG_LIBTOOL AC_LIBTOOL_CXX
