I made the same in the past with Raspberry Pi... which doesn't support OpenGL but only OpenGL ES
when you run an OpenGL app through SSH with X forwarding, the acceleration is done by SSH client, not by host
so running glxgears or Gem or whatever through ssh doesn't mean that the device your are connected to support OpenGL, unfortunately

I tried to render a rectangle once with Udoo and the Debian Wheezy image provided by Udoo from their website and it worked fine, without being full screen. I connected with ssh and XQuartz to display the GUI of Udoo, don't know if that is of any significance...

Yep, on the Udoo website :
API support for GPU Vivante GC2000 : OpenGL ES 1.1/2.0/Halti OpenCL 1.1 EP OpenVG 1.1 DirectFB 1.4 GDI/Direct2D X11/EXA DirectX 11 9.3
I can't see OpenGL.
Question : How Gem can run on Udoo if there is no API for OpenGL ? ++

Probably because it's running OpenGL ES *not* OpenGL which Gem doesn't have support for, as fas I know ...

hello,
UDOO board are advertised to be full openGL compatible. Since I've got an UDOO board with lubuntu installer, i tried to run Gem. i use Gem compiled from git.
i worked with major limitation :
- it's only in fullscreen, since opengl did not work on a window (udoo
limitation)
- pd crash when destroying the opengl context
so, it's not really usable.
cheers cyrille
