--- Comment #2 from Anton Shterenlikht <mexas at bristol dot ac.uk> 2011-09-25 20:24:24 UTC --- Gerald has provided a fix for the _Unwind_FindTableEntry FreeBSD ia64 issue (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45650). With this fix, 4.7 on ia64 FreeBSD now gives the same error: checking for ia64-portbld-freebsd9.0-gcc... /usr/ports/lang/gcc47/work/build/./gcc/xgcc -B/usr/ports /lang/gcc47/work/build/./gcc/ -B/usr/local/ia64-portbld-freebsd9.0/bin/ -B/usr/local/ia64-portbld-fr eebsd9.0/lib/ -isystem /usr/local/ia64-portbld-freebsd9.0/include -isystem /usr/local/ia64-portbld-f reebsd9.0/sys-include checking for suffix of object files... configure: error: in `/usr/ports/lang/gcc47/work/build/ia64-p ortbld-freebsd9.0/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. gmake[2]: *** [configure-stage2-target-libgcc] Error 1 gmake[2]: Leaving directory `/usr/ports/lang/gcc47/work/build'
