Can't include

Question

I\'m using Visual Studio 2010. I\'m trying to write simple Camera class in OpenGL. I need to include gl/gl.h in Camera.h
gl/gl.h is already included in main.cpp and Camera.h

Answer 1

Edit: Obviously Colin Hebert solved the problem, but as a general tip I`d like to say:

In Camera.h write

#ifndef _CAMERA_H
#define _CAMERA_H

above all other includes. And include all header files needed in your .cpp file in your .h file.

At least that`s what I think is best practice.
