I wanted to try out this nifty little project: http://code.fluffytapeworm.com/projects/libglfps
Turns out it doesn’t do shit. I tried it with Darkplaces and glxgears (as shown in the website’s screenshot) and the best I could have was :
freeglut ERROR: Function called without first calling ‘glutInit
I don’t know shit about OpenGL programming but I guess that the code needs to be updated for the newer freeglut versions (Tried it on Ubuntu 13.10 x64)
