I know this is a common title, but I don't even know what the problem is. I have been working on porting my OpenGL 1.1 app to 3.2 and I am not getting anything on the screen. I have set up all of my shaders properly, as evidenced by the fact that using a legacy profile gives me gorgeous results. It sounds like I need to set up a VAO, so I did it before I compiled shaders. Still nothing. I am getting no error messages, no crashes, freezes, or anything - just a window with a background color equal to the color I set with glClearColor. I cannot go in to too many details because I am using some Mavericks-specific code and that is under NDA, but even with non-Mavericks stuff running on Mountain Lion I am not getting anything.
Do I need to set up a VBO too? Do vertex arrays not work anymore?
In addition to answering those two questions, can somebody give me a good link to some Cocoa code (as much plain C as possible) that can help? All I can find with Google is a bunch of C++ and C# code that uses syntax I have never seen before, so I can't get much out of them.
