...hmm, this means it's not finding the function definition in your OpenGL headers...looking at the code, it should be coming from "Base/GemBase.h", but it appears that if you aren't on __APPLE__, you have to also define -DINCLUDE_GLEXT in the the cpp flags...if that doesn't work, then either you need newer headers, or your system simply doesn't support programmable shaders yet...
I dont know. I have built gem on another fedora core machine and had only one problem that I now automatically fix: I replace the -Wl,-shared with -shared in src/Gnu/configure because -Wl,-shared doesnt do what it is supposed to, and it does stop configure from passing my GL headders.
------- Additional Comments From jakub@redhat.com 2004-03-18 05:18 ------- That is to be expected. Never use -Wl,-shared, but -shared. With -Wl,-shared, you don\'t tell the gcc driver that you are trying to build a shared library, so it throws in crt objects for executable etc., but you tell the linker to create a shared library with that. With -shared, you tell the gcc driver that you are linking a shared library and it will take care of the details (putting in correct crt files, libraries etc. and of course also passing -shared to ld).
I modified the src/openGL makefile to include -DINCLUDE_GLEXT in the C++ flags but I get a big no go.

Anything else I can try? Thanks! -thewade
