have a problem compiling C program with GLUT

[ilia_kr]

I wrote some program for my CG class using GLUT in Microsoft Visual Studio 6.0. It works on Windows but doesn't want to work on linux. I have GLUT installed on Mandriva2009, yet GCC gives me errors:

 

$ gcc ex2.c

It seems like the compiler (gcc) doesn't know where to look for some gl and glut functions even though i've included 'glut.h' header.

 

I'll be glad to get some help on it.
