Cool What's the definitive way to know if GL is working or not?


At a console type the following: glxinfo | grep direct if it replies with direct rendering: Yes. Then GL _should_ be working.
-From Linux Gamers' FAQ.

Yes. If glxgears is working, then GL is working. If glxinfo reports Direct rendering: Yes, the GL is working *with* 3D acceleration.

What about GLUT. What is a definitive way of detirmining that GLUT is installed properly. And if it is installed properly, why don't some games see it and compile properly?

Thats right, and it is needed to compile opengl games and apps. It is very frustrating when I see a very cool opengl game such as Tux-a quest for herring appear to configure properly only to give the error "undefined reference to glutinitwindowposition" or something similer.

Some Glut applications seem to go ok, others don't. I don't understand why.
It is a shame because it is a very powerful toolkit for some very nice effects.

i see... well, this guy had a similar issue:

http://www.linuxquestions.org/questi...oto=nextoldest

try bumping the thread (by asking him to post what he did to get glut working right)...

from his last post, i gather it might have had something to do with library links, but i'm not sure...

Quote:
...i finally got a proper compile and the program works... i haven't got much experience in using library links in gcc...

here's a couple other threads you can look into:

i hope this helps... good luck...
