warning: ‘glutInit’ is deprecated: first deprecated in OX X 10.9 (glutInit(&argc, argv))

Who can teach me ? How to find solve?

That’s not a compiler error, it’s a warning.

It basically says that glut is deprecated and should not be used in new programs.

I guess that the developers at Apple would prefere you to use their system API instead of glut.
