I've just gotten a MacBook; it's not my primary Jitter machine, but I'm trying to see what I can get working on it. I'm having a lot of trouble running shaders, and I suspect this may not be the capabilities of the machine so much as shader instructions that require some tweaks.
Easily reproduced, for instance: the 42jSlab-compositeDV example doesn't seem to work at all:
jit.gl.pbuffer: error binding texture: GL Error: Invalid operation
error: jit.gl.texture: unable to create texture!
I have a similar shader of my own returning these errors:
error: -- START GLSL INFO LOG: fp ---
ERROR: 0.17: 'output': Reserved word.
ERROR 0:17: 'output': syntax error parse error
ERROR: Parser found no code to compile in source strings.
... I can provide that shader code if interested; it's just based on the 4waymix example.
Suggestions? Workarounds for compatibility? (Maybe switching to software execution?)
