Building StarGen

I've built StarGen so that it can compiled and run on both Macintosh and Unix systems. It can probably built on other systems such as Windows, especially those that run GNU C. The next two sections describe how to build StarGen on Unix systems, including Mac OS X, and on the Classic Mac OS.

Building StarGen on Unix

On systems with the GNU developer tools, building StarGen should be a simple matter. Simply cd to the directory where the sources were unpacked, and use the make command. Once you have created the stargen executable, you may freely move it anywhere. I keep mine in my private bin directory.
% make stargen
cc -c -O -g -W -Wall -Wno-long-double stargen.c
cc -c -O -g -W -Wall -Wno-long-double accrete.c
cc -c -O -g -W -Wall -Wno-long-double display.c
cc -c -O -g -W -Wall -Wno-long-double Dumas.c
Dumas.c: In function `dumasDumpHoard':
Dumas.c:746: warning: subscript has type `char'

Building StarGen on the Macintosh

The Macintosh versions of StarGen were created using Metrowerks Code Warrior.
