That is causing the above error. libgcc_s is backward compatible, so it is quite likely that it would work if you simply deleted the gcc 3.3.6 libgcc_s.so, so that both gcc 3.3.6 binaries and current binaries picked up the new libgcc_s.so. > I am very confused because if I switch to GCC4.1.0 that comes with > Fedora Core 5, there are no such errors.

I would guess that it is because the Fedora Core 5 gcc includes some patches which are part of gcc 4.2 rather than gcc 4.1.1. I'm just guessing, though. If you run "gcc --version" I expect it will say that it includes some Red Hat patches. Ian
