I have another problem, but I think that this is due to the SDK of MorphOS. The same error both with the cross compiler that with MorphOS. When I compile, for example, the file demo2 of MCC_THEBAR I have this error "/lib/libaboxstubs.a(GetAttr.o): In function 'GetAttr':
GetAttr.o(.text+0x6): undefined referencd to 'IntuitionBase'
GetAttr.o(.text+0x16):undefined referencd to 'IntuitionBase'
collect2: ld returned 1 exit status
