[GEM-dev] videoKINECT plugin for pix_video

Tue Mar 22 15:59:39 CET 2011

hi!

it's compiling against gem 0.92.3 and Pd-extended now but i have this 
problem:

load_object: Symbol "pix_freenect_setup" not found

it's working fine under linux so i don't really know where the problem 
is... maybe you find it or you don't have the same problem...?
