I am currently working on a project where I am sonifying weather data and intend to use GEM for a visual aspect to go with the sound. The project is fully automated on a Raspberry Pi 2.
After looking around the net, I saw that Raspbian Jessie (the build I'm currently using) had implemented an experimental OpenGL. However, when I go to enable it, I cannot find the option. Without detecting OpenGL headers, the Pi will not install GEM.
Has anyone gotten GEM running on Raspbian on the Pi?
