MC68000 cross compiler

[Kim Jørgensen <KIJ at infocom dot dk>]

Hi.

I'm trying to build a cross compiler on a Red Hat 6.1 (i686) system for a
custom MC68000 board (with a custom kernel). I didn't know what target to
compile for, so I chose m68k-coff. Can anybody tell me what coff means?

I'm using: Binutils-2.9.1, Gcc-2.95.2 and Newlib-1.8.2. I compiled and
installed the cross compiler using one-tree-1.6.sh and build-cross.sh
described in the CrossGCC FAQ. 

I didn't have any problems compiling or installing the cross compiler, but I
can't link compiled c programs. I tried to compile and link this simple test
program:

int main()
{
    unsigned int x, y;

    for(x=1; x<10; x++) y = 100 / x;

    return 0;
}

First I did a "m68k-coff-gcc -c -mc68000 test.c".
Then I did a "m68k-coff-ld test.o", I got these error messages:

test.o(.text+0x6):test.c: undefined reference to `__main'
test.o(.text+0x24):test.c: undefined reference to `__udivsi3'

When I tried to compile the test program for the 68020 I didn't get the last
error message (`__udivsi3'). Do I have to do anything special when making a
cross compiler for the 68000?


Hope you can help me out here!
