Is it a processor? Or an OS? > Or what? go32v2 is a so-called dos extender: It allows 32-bit programs to run on plain DOS. It was written by D.J. Delorie (http://www.delorie.com) Since FPC is a 32 bit compiler, it relies on the services of such an extender.

The best way to go about this is not to use the graph unit. The graph unit is provided for TP compatibility, but modern-day GUI systems do not work with the same paradigm. I suggest you look into using GTK or so. It's relatively cross-platform as well, and is quite well supported by FPC.
