tegra doesn't have full opengl driver support?
from gl4es.

there must be code already in there to force 16bits depth, I'm pretty sure of this. Look around in the glx folder
from gl4es.

thanks, manages to get it to go a bit further overriding the depth to 16, then it was crashing on the testGLSL function in glx/hardext.c to test the verion so i bypassed that as the tegra is on version 100. it's now finishing the load of the libGL and now i'm hitting this warning
