Your call to glClearColor () has only 3 arguments but you need to also supply the alpha argument so you need one more 0.0 or whatever you want to pass. Also, you have a syntax error on the "return0" statement. You probably don't want to be using Dev++ and glut either as both are quite old. The free Visual Studio Express C++ from Microsoft or minimalist gcc for Windows along with Code::Blocks or Eclipse is a better choice. Use freeglut instead of glut. Another thing, why not try learning modern OpenGL 3/4 instead of the old classic OpenGL? Unless you're planning on working with legacy code I really don't see why you would want to learn it. But if you are learning it, then just go to the [url="http://nehe.gamedev.net"]NeHe[/url] website--it will answer almost all your questions.
