Can't be that the unresolved references are from the code I want to add to
BrickOS, because I also tried to compile just the BrickOS-files (without the
code I want to add) and the same errors appeared.

I looked for some of those references and all of them are defined as extern in
some header-files. So they must be declared in an assembler-file , isn't it? And
by the way, I searched the whole directory - even the header files - so those
unresolved references are defined nowhere in the whole BrickOS-folder.
Where can I get some information how to define these macros?
I also examined the make-files. I am not really good in reading make-files, but
I think there was nothing which could help.

| Hi Rudolf, (...) No. Some _are_ defined in .h-files. And the register sets come via h8300.rcx to boot/brickOS.lds. Is it possible that your compiler chain treats leading underscores different.
