I've posted this problem already on another thread, but I think it was probably the wrong one
(and it was too old) so I post again.
I tried to compile Stellarium, an application that needs opengl and sdl.
I used the cross-compiling sdk for rc11 and the program compiled fine.
However, when I try to run it on the my C750 I get the message:
sdl: Couldn't set 640x480 video mode (X11 driver not configured with OpenGL), retrying with stencil size 0
sdl: Couldn't set 640x480 video mode: X11 driver not configured with OpenGL!
(the message is the same for resolution 320x240).
glxinfo however reports that openGL is enabled and glxgears runs (although at a mere 17 fps).
I have also the "mesa3d" package installed.
You can find the ipk I made at stellarium_0.7.1_armv5tel.ipk if you want to have a try at it (it is a little heavy, 16MB, i didn't strip the constellation art and stuff...)
I would be really grateful for any help. Stellarium is a really cool "desktop planetarium" app, with a very beautiful rendition of the night sky (as seen from any point on earth).
Thanks for any pointers,
