These days I am working on porting the iGame to AmigaOS 4, compiling it with vbcc and using the latest SDKs. Although that I have it compiling without any errors, the app crashes on MUI Label() method, at line https://github.com/MrZammler/iGame/blob/master/src/iGameGUI.c#L259
I compile it with the following command
vbccppc -quiet src/funcs.c -o= /tmp/filexgdr56.scs -dontwarn=-1 -I/opt/sdk/ppc-amigaos/Include/include_h -I/opt/sdk/MUI_5.0/C/include -D__USE_INLINE__ -elf -no-regnames -no-multiple-ccs -madd -c99 -use-commons -O=1023 -I/opt/vbcc/targets/ppc-amigaos/include -D__amigaos4__
I am not sure, but if there was something missing, I guess I would get some errors on compiling. On the same environment I compiled MUI examples, like MUI-Demo, and they work just fine.
Thank you all for your help.
