according to my reading of info nodes: (libtool) AC_PROG_LIBTOOL (automake) Flag Variables Ordering
the shell variable CFLAGS should have no value after AC_PROG_LIBTOOL. i.e., i should expect the configure.ac fragment: echo "CFLAGS: $CFLAGS" AC_PROG_LIBTOOL echo "CFLAGS: $CFLAGS" to create a configure that outputs "CFLAGS: " both before and after whatever code is generated as the expansion of AC_PROG_LIBTOOL. is my interpretation correct? presently, i see that before, CFLAGS is indeed empty, while after, it has the value "-g -O2" (compiler is gcc), using libtool 1.5.22, autoconf 2.60, automake 1.9.6. to see for yourself, try: $ mkdir /tmp/z $ cd /tmp/z $ cat > configure.ac <<EOF AC_INIT([foo],[0],[ttn]) AM_INIT_AUTOMAKE echo "CFLAGS: $CFLAGS" AC_PROG_LIBTOOL echo "CFLAGS: $CFLAGS" AC_CONFIG_FILES([Makefile]) AC_OUTPUT EOF $ touch NEWS README AUTHORS ChangeLog Makefile.am $ autoreconf -is $ ./configure i suppose the "-g -O2" is good to have *somewhere*, which would lead, presuming the observed behavior is undesirable and will be fixed in some future libtool, to the follow on question: if not CFLAGS, then where? thi _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
