Hi,
I have built os mesa 6.5.3 on IBM BlueGene/L, i.e. for the compute nodes of
this super computer.
I used a slightly modifed linux-osmesa config file for that, the diff is
attached. BlueGene doesn't have shared libraries and doesn't support
multithreading. The resulting osmesa library works, it renders correct images
(what I have tested so far).
I tried to copy that file to a different name (bluegene-osmesa) but didn't get
it working. What do I have to change for that ? Is there a chance that this
might go in the official mesa sources (so I don't have to do this manually
everytime I need it) ?
Bye
Alex
