Hey Ali, I'm interested in trying out the udoo. After October I should have some time to work on getting gem running on it. I think any advances on the udoo should translate to the Pi and vice versa.

hello friends, i'm very keen to try GEM/openGL on a Udoo board (http://udoo.org) which DOES support OpenGL. if anyone is up for trying it i can provide you with a board to try on. should be a load of fun :)

I'm curious to know if this works as well.
Judging from the short readme, do the following on the RPI commandline (not tested).
Long story short, you install git & cmake, then get the glshim source from gihub and build it. After that, you need to add the path to the built library files (.so) in the glshim folder so the system knows to look there and load that GL instead of the main system GL in /usr/lib.
The main issue with the RPI is that it doesn't support old school GL, only GLES, so the intermediate mode commands etc don't work. glshim appears to be a wrapper that adds the functionality on ES. It may be a little slower, depending on how they've built it, but it should work ...
#####
cd ~/ mkdir src cd src
sudo apt-get install git-core cmake
git clone https://github.com/lunixbochs/glshim.git cd glshim cmake . -DBCMHOST=1; make GL
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/src/glshim/src/libGL.so.1"
~/.bash_profile
#####
... now logout and login try GEM
If that doesn't work / has problems, then as the readme says, you might need his patched version of glu, sooo:
#####
cd ~/src git clone git@github.com:lunixbochs/glues.git git checkout glu cmake . make
#####
Then edit the LD_LIBRARY_PATH in ~/.bash_profile and add the location of the compiled glues (not sure, there's no info in either repo readme):
#####
leafpad ~/.bash_profile
#####
Find this line (was added earlier):
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/src/glshim/src/libGL.so.1
and add a new search path to the glues lib location you just built to it. As I said before, you'll have to find the .so lib files you built in the glues folder to knwo which path to add:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/src/glshim/src/libGL.so.1:$HOME/src/glues/PATH/TO/LIB/SOS
Good luck.

Thanks dreamer,
I'll see if I can get that to work. Git confuses the hell out of me but the install instructions look pretty clear. Have you tried this? If so does GEM just work once glshim is installed?
cheers

Perhaps have a look at glshim: https://github.com/lunixbochs/glshim
Not all GEM functions are working yet, but anyone porting to GL ES could start there.
