Hello.

I'm making a little multitasking kernel in C for an autonomous guided
vehicle equipped with a MC68008-computer.

I use gcc-2.4.5 on a Sun 3 workstation for compiling the code
before sending it to the AGV in Motorola's S-format.

I would like to know if anyone have done the same thing, i.e. made
programs for a MC68000 on a Sun 3. 

One of my problems is, that a piece of code need to be linked with
two functions from libgcc.a : ___udivsi3 and ___umodsi3.
It works when I test it on the sun, but if I use it on the MC68008
I get an IllegalInstruction-exception. I think this means libgcc.a
contains non-MC68008-instructions, and that may be because the sun 3's
got a MC68030 inside. I have tried to compile gcc-2.5.3 after modifying
the makefile to use the -m68000 -flag for compiling. But with no succes.

If anyone has got a library for the MC68000/MC68000 that works, could
you please send me a mail?

I'm also interested in hearing from people with experience in programming
operating systems in C. I find it difficult to interface my assembly-functions
to C. An how-I-managed-to-make-an-operating-system-in-C -story would be very
interesting reading indeed.

Thanks in advance.
