Hello guys , I try to install Gl4ES (https://github.com/ptitSeb/gl4es) with success , in armbian Ubuntu Xenial Desktop . For GL4ES you need to "put libGL.so.1 in your LD_LIBRARY_PATH". LD_LIBRARY_PATH is "/usr/lib/arm-linux-gnueabihf" in the same path you need find "mesa" folder and rename it to ".mesa", maybe is the same for glshim.
You can run games like foobillard++ , openarena,quake ,etc .
Gl4ES is a wrapper for OpenGL 1.5, but the Hardware accelerated for chromium or firefox doesnt work.
