I am working on a project that needs to compile on several platforms (Linux, MacOS X, and CygWin on windows). I''m having a great deal of trouble compiling it on MacOS X. It keeps returning that it can not find any of the opengl function''s that I am calling. I''m assuming my makefile is screwed up, is there an example of a MacOS X makefile, that works, somewhere? thanks in advance Altp.
