But the symbol itself is provided by something. I can see its definition in
Immunix's glibc/stackguard patch. Do you have glibc compiled with it as
well?
The patch I'm talking about is
http://download.immunix.org/ImmunixOS/7.0/i386/extras/glibc-2.2-StackGuard.patch
(easy to point to but outdated)
There is a new version of it in
http://download.immunix.org/ImmunixOS/7+-beta/SRPMS/glibc-2.2-12_imnx_19.src.rpm
