Hi md,
Linking with C files works just fine. No problem with that. However I
would like to link regular FPC object files instead. Please see the
three files I attached in my first email. For some reason the linker
could not find the implemented procedure. So the question is, how to
modify the implementation unit so everything works.
Regards, Darius
