Hmmm, perhaps your dev environment is missing GLUT and OpenGL ‘frameworks’, or you are missing some config like a path.
Typically on other platforms you download these libs and/or install them with a driver or SDK and then include the header files and link to them and it just works.
I’m not familiar enough with Mac to help you with this ‘framework’ malarkey though. I expect OpenGL is there by default but perhaps not GLUT. So if you can’t find GLUT don’t assume you have a problem. You could use AGL etc. for your platfform specific interface given that GLUT tends to be non core functionality (again I don’t know whether it ships & installs with the dev environment by default, but I’d look for OpenGL and AGL first).
Try Apple’s developer articles, here’s one on OpenGL:
