I have a configure.ac which calls: AC_CHECK_SIZEOF(int) This fails on a machine (a FreeBSD 6.1-RELEASE / Itanium) with: checking size of int... configure: error: cannot compute sizeof (int) And config.log contains: configure:22234: cc -o conftest -g -O2 -I/house/bortz/include -L/house/bortz/lib conftest.c -lpopt -lm >&5 configure:22237: $? = 0 configure:22243: ./conftest /libexec/ld-elf.so.1: Shared object "libpopt.so.0" not found, required by "conftest" [libpopt.so.0 is in /house/bortz/lib] Indeed, I need popt so I passed --with-popt=$HOME to configure. The code compiled through libtool seems fine with it but autoconf's tests like SIZEOF does not go through libtool and are not executable unless I manually set LD_LIBRARY_PATH, which is inconvenient. Any idea? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
