I''m just wondering if NeHe''s SDL port would work on a Mac. I''m using Windows myself, but I need to write a prog that runs on both Windows and Mac. Do I need to compile the code on Mac computer? if yes, what compiler does Mac use?

If Nehe''s code is a full SDL port(and so is yours) it should be able to run on any OS that has ogl support(linux, bsd, mac, win). What mac compiler to use I have no idea. Mac X might be able to use gcc since its based on BSD. Google it.
