The programming system comes in several lha archives with the needed directory structure. Simply make a directory (gccdir) and extract the archives in it. Then add to your user-startup file: assign gcc: gccdir assign glib: gcc:glib path gcc:bin add Then make a directory named gcc:amiga_include, get from Cbm the Amiga OS include files and put them in that directory. That's all folks. Davide Pasetto
