OK So I followed the instructions listed here: http://wiki.allegro.cc/index.php?title=Install_Allegro5_From_SVN/OSX no problems with the download or install but I did get a few warnings about DUMB, PhysicsFS and some other stuff I assumed were the optional support libraries. I go to compile a test program on the Desktop and boom: Couldn't find Allegro.h. No idea whats going on I just assumed allegro would be available. I compiled with: gcc myfile.c -o myprogram `allegro-config --libs` from: http://alleg.sourceforge.net/stabledocs/en/build/macosx.html FYI I did not do the XCode install because quite frankly I don't like XCode. I'd rather do nano or TextEdit if I need to look at more than one piece of code at the same time. So all you fan boys find someone else to proselytize to. But push come to shove I'll try it out. I'll also try the other compile options as I was running late for something when I tried this so I'll give it a go later. ... wait wth is a backtick and how do I do it. But if I got that wrong why did it spit out the normal routine errors? Instead of not compiling? Honestly I'm just a newbie who would like to try out a GUI framework just to make it more fun.
