Ok. Here's the problem. I am trying to get a pre-compiled version (no source available) of SGI Performer 2.4 working under Gentoo. Gentoo is a new 1.4_rc3 install using gcc 3.2.2. When compiling my application, which uses Performer libraries, I get the following erros:
| Code: | /usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.2/../../../libpf_ogl.so: undefined reference to `__pure_virtual'

I have traced to problem to the fact that neither libgcc, nor libstdc++ contain these symbols. I tried a work-around https://forums.gentoo.org/viewtopic.php?t=35008&postdays=0&postorder=asc&start=25 that was used for mozilla and the same problem. This work-around only worked for a couple of the symbols, namely __pure_virtual and the builtin_ bunch. I am attempting to migrate from Redhat to Gentoo on my work machine, and I found that if I use the Redhat libgcc and libstdc++ (2.95) libraries, then the build is successful (I have not tried running it yet as I am currently under Redhat.) I don't know that this is necessarily a Gentoo problem, but I don't know enough about gcc and glibc to know the difference. Perhaps some one can bring some light to the subject.
Thanks,

Could you try installing lib-compat?

Thanks for the reply. I finally figured out that is what I needed.
