hi,
I want to experiment with npr shaders in quake and thought this project would be well suited for this task.
has anyone managed to build this with os x 4.10 and xcode 2.4? I am getting an error message: asm blocks not enabled use -fasm-block? where do I set this flag. I'm new to xcode and can't figure out where to set it. or is there another problem?
regards,
simon
