Does anyone know how I can cross-compile software for a 1999 iMac G3 with a PowerPC processor? Are there resources on how to develop for this CPU and is there any community around it?

@dr_robotBones Retro68 is a gcc-based cross compiler not only for 68k-, but also PowerPC-based Macs running classic MacOS:

IMHO, this is one of the best options if you want to develop on a modern system.

I have heard of this before, I'll have to learn how it works.
