someone tell me i must recompile the gcc with libunwind enabled, so i copy the intel-icc9-libs(include libunwind) to /usr/lib, and type
#rpmbuild --rebuild gcc-3.4.6-8.src.rpm
#rpmbuild --rebuild glibc-2.3.4-2.36.src.rpm
but after these work done, i disassemble the libc and found it still use the old call style(int 80)
so it seems that the gcc source of redhat didn't use the libunwind
any idea ? thanks in advance !!
