Hi, Roland Smith writes: > According to the manual page (1), glGetString returns 0 when an error > occurs.

Maybe the latter is the case here? > Because otherwise it should just return a pointer to a static string. As far as I can see, it is not between a glBegin and glEnd call. Is there something like an error buffer I can query to see what went wrong here? glGetError() also returns null.... Isn't there something the program should do before glGetString returns something? I mean, may I just include the printf's in a "hello world" C program and they just return the requested data? Probably not - or?
