I get a problem with gl/glut.h when using xcode

Since GLUT is its own framework on OS X, did you try including glut.h with the path to the GLUT framework, like the following:

#include <GLUT/glut.h>

Also, on OS X including OpenGL headers should use OpenGL instead of GL in the include path, such as the following:

#include <OpenGL/gl.h>

Glad that helped, Mark actually mentioned changing the include to use GLUT in his first response to you.

how can I know if some thing has changed in the programming language or not?

Good question

I don;t use these libraries in my normal work, I compiled that one program to see if it would work with that change and to see if there were any other problems I might have been able to help you with,

At this point the basic question of using the GLUT and OpenGL frameworks seems answered. For individual problems with specific examples from that site you will need to try to debug it or else search for an answer.

For example in the fifth program by the values X,Y an Z in the enum have been already declared in

#include <GLUT/glsmapint.h>

which is why you get that error message. If you change that enum to

enum {w = 3};

the code compiles and runs, but this isn't really a comfortable fix for this problem.

Now that you have the basics of how to write and compile using these libraries you will need to familiarize yourself with the usage in OS X.

good luck, looks like interesting work.

Here's a link to OS X specific information about using OpenGl OpenGL Information

Since the source code files have the extension .c, I'll assume they were written in C. Of course you could click the links next to the source files and check for youself.

I don't use GLUT so I won't be able to provide further assistance on using GLUT.

I don't use any C GUI libraries so I can't provide you with any advice on one to use. Most people who write Mac GUI applications use Cocoa and Objective-C.

I answered your original question. If you're looking for advice on other topics, I recommend asking a new question.

I created a command line C project, added the GLUT framework to the project copied the code from cube.c and it compiled and ran fine.

Xcode 5.1 and 10.9.2

One change to the source. the include needs to be changed from

#include <GL/glut.h>

to

#include <GLUT/glut.h>
