Hi Davidm
Thank you for your answer.
I removed -Werror and let it run again. Same result as before. You are
probably right with your saying that the 2.95.3 toolchain is a bit old.
I have the feeling the the option --end-group used in the script is the
cause of the problem. Hence it seems, I need a more recent toolchain.
The problem is now: Were to get it? I googled for "m68k-elf-tools" and
was lucky to find a hit. But when downloading from there
(www.uclinux.org/pub/uClinux/m68k-elf-tools) the file I get then is
m68k-uclinux-tools-20061214.sh. The name of this file confuses me,
because it tells me the toolchain would be ok to build applications that
run under uClinux. However, uClinux itself does not run under uClinux?
Does'nt it? I really am confused and I can find nowhere a more recent
m68k-elf-toolchain.
Regards Bob
