Re: Problems with GLUT application

the trace of functions called is like:

glutInit(&argc, argv)
glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_DEPTH)
glutInitWindowSize
glutInitWindowPos
glutCreateWindow

glutDisplayFunc
glutReshapeFunc

... after this the first "real" gl functions are called:

glPixelStorei(GL_PACK_ALIGNMENT,1)
glDepthFunc(GL_LESS)

 When running the program it crashes at the first gl-call.
(glPixelStorei, or when commented out glPixelStorei at glDepthFunc....)

It's not legal to make GL calls before you have an OpenGL context. On Linux and Windows they'll silently fail, on the Mac you'll crash.

In GLUT's case, that means that you must call glutCreateWindow or glutEnterGameMode before making any GL calls.
