My system is Ubuntu Lucid 64 (LTS)
I installed all J addons via pacman, right from the start!
When I try to run something like:
load '~addons/demos/opengl/simple/gldemos.ijs' or
load '~addons/demos/opengl/demo/gldemo.ijs'
the GTK windows open properly, but nothing is rendered, the message
returned is:
cannot alloc opengl context
locate libGLU gives:
/usr/lib/libGLU.so.1
/usr/lib/libGLU.so.1.3.070701
/usr/lib/mesa/libGL.so.1
/usr/lib/mesa/libGL.so.1.2
/usr/lib/nvidia-173/libGL.so
/usr/lib/nvidia-173/libGL.so.1
/usr/lib/nvidia-173/libGL.so.173.14.22
/usr/lib/nvidia-173/libGLcore.so.1
/usr/lib/nvidia-173/libGLcore.so.173.14.22
/usr/lib32/libGL.so
/usr/lib32/libGLU.so
/usr/lib32/libGLU.so.1
/usr/lib32/libGLU.so.1.3.070701
/usr/lib32/mesa/libGL.so.1
/usr/lib32/mesa/libGL.so.1.2
/usr/lib32/nvidia-173/libGL.so
/usr/lib32/nvidia-173/libGL.so.1
/usr/lib32/nvidia-173/libGL.so.173.14.22
/usr/lib32/nvidia-173/libGLcore.so.1
/usr/lib32/nvidia-173/libGLcore.so.173.14.22
So it's all there, I wonder if there is some library conflict, since there
are so many versions.
I mean, how does the system resolve which one it should be using?
