You must link glut32.lib and glaux.lib to your compiler.
there two methods to do this.

  1. link the libraries in the compiler setting
  2. write this #pragma(lib,“glaux.lib”);
    and #pragma(lib,“glut32.lib”);

you must also link opengl32.lib and glu32.lib

Yeaaa!! For a complete description, click in “Project” “Settings”.

After a new Screen appear, click in “Link”, and in the label “Object Library/Modules” add the text “opengl32.lib glu32.lib glaux.lib”

Your code must compile without errors now!

Fernando: he is using the Free compiler tools - they don’t have any IDE

Fernando, what you described sounds very much like MSVC. gordon9728 said he was using Borland’s compiler.

And bondi, did you foget a “comment” between “#pragma” and “(”?

#pragma comment(lib, “blah.lib”)

Here’s a tutorial page for you to check out:
http://home.clara.net/paulyg/ogl.htm

It comes with a tutorial on how to use the OpenGL API with Borland Command Prompt tools. What I think is wrong is you need a later version of gl.h, which you can also download from here.
