[Jprogramming] OpenGL on Linux

[bill lam]

You must use a very old version of J602 base library, please update
base library from pacman first.

The opengl (or simple opengl?) demo requires osmesa in linux j602,
so I guess you still have to install that package, try in your shell

$ sudo aptitude search libosmesa

to obtain the actual package name, and install it if there is no
conflict.
