Hi ! I decided to start working with OpenGL, so I''ve installed MESA on mi Linux machine and downloaded an OpenGL tutorial, but when I tryied to run the first program of the tutorial, a message says: XLib: extension "GLX" not supported by server and after installing the Qt module for OpenGL (I guess that would be easyier) it says: XLib: extension "GLX" missing on display "0:0" can someone help? thanx!

BTW

I tryied to compile the program that comes with the tutorial I downloaded, and I compiled it with:

$cc -o uno uno.c -L/usr/X11R6/lib -lGL -lGLU -lglut

no errors, no warnings, no nothing... but when trying tu execute it:

$./uno
GLUT: Fatal Error in uno: OpenGL GLX extension not supported by display::0.0

and thats all... nothing else happens...

Did you load the GLX module for your X server?
You should have something like Load "glx" in your XF86Config file.
