I think I see the real problem now. The OP is using GCC 3.4.3, which does not have this patch: http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02353.html That patch was added in GCC 4.0. It changes GCC to use the SHT_AMD64_UNWIND section type for the .eh_frame section on x86_64 Solaris. I think the effect is that version of GCC before 4.0 do not properly support Solaris 10. Ian
