no, glut should not be needed. how did it complain?
i'm sorry i didn't note the error and now I've forgotten! it was missing a GL/?.h
anyway, I finally compiled it but when I try to load it in pd i get this error in pd console:
undefined symbol: _ZN12pix_contrast18processYUV_AltivecER11imageStruct
... Altivec ?!?! (i'm on i686)
what am I doing wrong?
