install error when compiling tesselate.h

[Ummon]

After running ./buildg3d all, I get the following errors:

What do I need to do to fix this?

I think we saw these errors a long time ago. What version of GCC are you using?

corey

[Ummon]

i686-apple-darwin8-gcc-4.0.1

It is what I had on my Mac OS 10.4 installation. I have the latest
(for 10.4) XCode 2.5, so wouldn't the gcc also be up to date?

[Morgan McGuire]

I think OS X 10.4 had broken OpenGL/GLU headers that used an incorrect definition of gluTessCallback.  You can patch yours to work by just casting the argument on that line to what it wants in the G3D sources.  We removed the patch because there was no easy way to detect 10.4 vs. 10.5 with a #ifdef and our OS X developers had moved to 10.5.
