Hello,
1. I am getting the same error "*Xlib: extension "GLX" missing on display
":0.0".*" with '*glxinfo*'. I will try to fix this issue.
2. Meanwhile, is there a way test the code without 'OpenGL' support? I
tried "*cmake ../brlcad-code -DBRLCAD_ENABLE_OPENGL=OFF*" but it is not
helping.
Regards
Shailesh
