I'm trying to get the first (2nd) of NeHe's OpenGL tutorials, to compile for PSP, using the PSPGL libs... Right now I will post my Code, Makefile, and compiling error. I have been unable to find a tutorial on this, so as of right now, I'm just winging it, and I hope to write some sort of documentation about this in the future so any help is much appreciated.
