compiling issue - Ubuntu -> Eclipse

Hi All,
I just yesterday installed ubuntu on my pc (now I have dual boot with Vista - where open GL works without problem) and when I want to compile one openGL program the compiler can not find open GL. This is what I get on every openGL function (the variable is different):

Description Resource Path Location Type
‘GL_COLOR_BUFFER_BIT’ was not declared in this scope openGLtest.cpp openGLtest/src 28 C/C++ Problem

please where can I define it?

#include <GL/gl.h>

thanks for the reply but that does not work. Should I include it also in a project? (Glut have already included…)

you should make sure the path to GL directory is known. can be either hardcoded or setup in project settings (include directories).
you could test some NeHe ubuntu samples and see how they do it.

No gl.h header ?
try locate gl.h to be sure.

Maybe you need to install a dev package too, ie. freeglut comes with all .h needed for gl development, I guess for ubuntu it is called like this : freeglut3-dev
