Kevan:
I wish you luck. I've had to give up on GPC because it fails to compile on MacOS. I think this neglect means that GPC is going to go defunct on all platforms. In contrast, the community of the Free Pascal Compiler (FPC) is alive but I still can't compile there. I can offer you translation to C: https://alum.mit.edu/www/toms/pascalp2c.html Unfortunately it does not do syntax checking and so can produce bad binaries. I currently use FPC to check syntax and if that works, then translate and compile in C.
