Hi Joel, Kai and all,
Thank you for your response - I appreciate the great willingness of many
people who are going out of their way to help me.
I will try to respond to the questions below:
> Ok, First to clarify. (My assumptions)
>
> hello.map is failed build map on unix system
> hell1.map is successful map from windows tools system
> rm_rom.ld is linker script used for both builds
The above are correct assumptions.
> ll is working windows script for windows tools
ll is LL.BAT which calls ld and then objcopy.
> ?? script on unix
It is called 'compile.sh' and is a small script of my making to mimic the
steps that are taken on the windows system.
> Comments

I actually noticed that this morning. If I run the following ld command on
unix:
# m68k-coff-ld -v -o hello.cof -T rm_rom.ld -M > hello.map
I get the following:
rm_crt0.o:rm_crt0.S:149: undefined reference to `main'
./libc.a(exit.o)(.text+0x52):exit.c: undefined reference to `_exit'
./libc.a(sbrkr.o)(.text+0x12):sbrkr.c: undefined reference to `sbrk'
In the meantime, I have copied the entire "../mcpu32" directory from the
windows machine to a unix directory, and with the following command:
m68k-coff-ld -v -o hello.cof -L/hfs/mcpu32 -T rm_rom.ld -M > hello.map
I get the following:
rm_crt0.o:rm_crt0.S:149: undefined reference to `main'
So, there must be something else in that directory that is influencing the
link. Also, it should be noted that I can compile hello.c successfully in
unix - it is just that the resulting S-record file does not run on the
board. I wonder if this is related to the incorrect __vector*_defaults
mentioned below.
Please note that I also copied the rm_crt0.o file from the windows side, as
well. In the map file from the above command, which is enclosed as an
attachment, I'm still getting the problem with the __vector*_defaults that
Joel pointed out. Is there a reason for that? I am also enclosing the
rm_crt0.S file if there might be a hint in that.

Things are different with the use of the entire mcpu32 directory from
windows, there is just the one undefined reference - to 'main' coming from
rm_crt0.o. Any suggestions for fixing that?
Another thing that bothers me is what seems to be a big difference reflected
in the .map files from the unix compile (hello.map) and the windows compile
(hell1.map). In hell1.map, many many different archive members are included
while far fewer are shown in hello.map - is this because the link for
hello.map was aborted due to the problem finding 'main'?
> 4. Your rm_crt0.o are not the same! notice the differences for your
> __vector*_defaults in the two
Well, I brought the rm_crt0.S file over from windows and compiled it to
produce the rm_crt0.o. Is there something I should inspect in it to see why
this happens?
As mentioned above, I also brought over the rm_crt0.o file from windows, and
it still produces the same problem with the __vector*_defaults. I don't
quite know where to turn at this point...
