I've transferred my Delphi game so that it compiles under Free Pascal. I then changed the settings so that I could compile a Linux version. The problem I am seeing is with the "genmath.inc" file. As it compiles Free Pascal stops with the message "Program generated a RTE 33 at address xyz. Save your sources and restart the IDE." I ok the error and it then says "The IDE generated an internal error and will now be closed." I have Lazarus installed and this is where Free Pascal is grabbing the units and include files from. Anyone got any ideas or had a problem with the "genmath.inc" file ?
