After making the change to libgcc/config.host that is also described in comment #5 I get the same. libc indeed does feature _Unwind_FindTableEntry() as I can easily verify with the following program: void _Unwind_FindTableEntry(); int main() { _Unwind_FindTableEntry(); } Just, why do we then get this link failure? Adding -v I see that /lib/libc.so.7 is explicitly part of the collect2 invocation. -- gerald at pfeifer dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2010-09-07 23:19:36 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40959
