Unfortunately, my code generates a lot of errors when compiled with GCC on OS 4.1 due to differences in the Development settings. I.A. can't help me because he doesn't know much about OS 4.1.
Now I'm not sure if my Development environment isn't installed correctly on my OS 4.1.
In emulation mode, installing an SDK on OS 4.1 is almost impossible—the emulator always freezes.
I think I've managed to compile an OS3 version; I'm testing it right now. We can talk about it in Italian on Amigapage, and before I publish it, I'll send you a copy via PM for you to test.
I don't think so; there's probably something missing from my OS 4.1. In any case, the OS 3 version I created seems to work with: AMiGA OS 3.1, OS 3.9, OS 3.2, OS 4.1, and AROS 68k
