Question

I’m trying to run some working C++ OpenGL code on the iPhone. So far, I managed to run an Objective-C/OpenGL ES example on the iPhone, and some Objective-C->plain C++ file (“hello world” output to the console).

But I can’t any C++ OpenGL code. The exact problem is including the OpenGL library in the C++ file:

If I use the imports for Objective-C:

#import <UIKit/UIKit.h>
#import <GLKit/GLKit.h>

it will say at all gl* calls “Use of undeclared identifier ‘gl*'”.

If I use the imports I use in only C++:

#include <OpenGL/OpenGL.h>
#include <GLUT/glut.h>

It says OpenGL/OpenGL.h file not found (which I had expected, since OpenGL is full OpenGL library, not OpenGL ES).

So how do I use this C++ file?

Already searched:

But I don’t find how to use the C++ file.

Try:-

#include <OpenGLES/AEGL.h>
