SteamDraw has been AGG for >15 years so it does work.

Whenever I hear someone talking bout a port I just see someone who hasn't done even the most basic homework. AGG will compile out of the box. Well not 100% you need to create Makefile.in for MorphOS (AFAIR I just renamed the Linux one) and adapt a few include path.

Don't wander into examples area thinking you have to port the GUI toolkit found there, most can just run on the SDL backend (which is something I never really to investigated).

-> get the library to build (if really needed I could send you a copy of mine)
--> get your app to find all the includes and link to the lib
---> fix whatever other dependancies remain
