Hello
How can i be sure that somebody have OpenGL installed on his/her linux?
In example: an requiring library that evry opengl implentation has.
Thanx Hylke

I have found that If i can use glxgears , and the frame rates indicate that the 3d acceleration is going on than all the proper libraries are in place,,,

Also check to make sure the video card says 3d support enabled. What graphics card is it?

glxinfo will tell you if opengl is working... Tells you all the gl functions available.

But what i mean is:
I'm writing a bash script that needs to check if opengl is installed.
So how can i do that?
btw, from glxgears:
16134 frames in 5.0 seconds = 3226.800 FPS
:P

A script to grep glxinfo?

No i mean:
I've written a program that requires OpenGL, so i want to check if the user has OpenGL installed.

I thought a script that ran glxinfo and grep'ed the result might do that, by looking for key statements in the glxinfo output like Direct Rendering: yes and various glx etentions, etc...

Uhmm..
I dont really understand what you mean.
I just want to know if a user has OpenGL installed using a bash script.
Thanx Hylke
