Hi Kai and everyone,
Kai writes:

Thank you for pointing out the usefulness of the -verbose flag. It
definitely helped me find a 'duh' error - I had neglected to put a reference
to hello.o on the ld line - which explains why it was having trouble with
'main'.
I have rectified that and have produced an S-record file on the unix side
where I have referenced the windows libraries.
I am enclosing the resulting ld maps (using the -verbose flag) from the
windows compile (hell1.map) and the unix compile (hello.map).
I will try downloading the resulting file to the board to see if it works.
However, something that Joel pointed out yesterday is still a problem.
(There also may be other problems, but I am just now starting to learn how
to read and use a .map file!)
Here are some snippets from the .map files that show a problem with the
definition of the vector*defaults.
Here is a snippet from the map file produced under windows:

And here is the same snippet from the unix compilation:

----------------------------- clip ------------------------------
Does anyone know why there is a difference between the two links for these
vector*defaults? What controls the definition of these? I am including the
rm_crt0.S and rm_rom.ld files if they are useful in figuring this out. BTW,
the rm_crt0.o file that I have used for this compile is the one that was
used under windows - does this suggest that something else is controlling
the definition of these defaults?
Any thoughts?
