Thanks for the tip on the src files James,
So, I was able to compile Gem.pd_darwin with one caveat...my Gem.pd_darwin is 12.6MB whereas the G4 distribution is 17.9MB. Obviously, something went wrong here. For grins, I tried to run PD/GEM with the version I compiled. PD loaded, I saw the console window and then it quit without saying anything not even about GEM. I thent tried it with the G4 distro from iem and everything was normal. At this point, I have no idea what went wrong. I have all of the files/frameworks etc. The last thing I was having problems with was trying to get Xcode to find libftgl.a. I gave the project a path to this file in the resource path settings and it compiled.
I did do one thing that I wasn't sure about. I made an errant click in the xcode project, but I wasn't sure what exactly I did. I ended up getting some erorrs that I hadn't seen before and unchecked gemextwin.cpp and gemextwin.h from the project since they included /Base/GemOutput.h.
During compilation I had 41 warnings which looked mostly harmless to me from tube.h, pix_texture.cpp, pix_halftone.cpp, model_loader.cpp, GemPixUtil.cpp, and pix_videoDarwin.cpp.
Maybe someone has come across this situation before? Any suggestions?
best, wes
