Tobias Burnus <burnus at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |burnus at gcc dot gnu.org --- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> --- Created attachment 49313 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49313&action=edit configure.ac patch I think there is an ordering problem in the top configure.ac: *-*-freebsd*) if test "x$with_gmp" = x && test "x$with_gmp_dir" = x \ && test -f /usr/local/include/gmp.h; then with_gmp=/usr/local fi ;; and later: if test "x$with_gmp$with_gmp_include$with_gmp_lib" = x && test -d ${srcdir}/gmp; then Thus, the in-tree-build check fails if with_gmp is set. Can you try the attached patch? I currently do not have a BSD system at hand.
