Cross-Compiler gcc 3.1 & MacOSX

[Edoardo Franzi <edoardo dot franzi at ukos dot ch>]

Gentlemen,
I would like to use gcc compilers to create a cross-compiler for 68k
targets. I have tried the following procedure without success. Can someone
help me?

Thanks
   Edo.


I have the following packages inside a commun folder (Gcc) in my workspace:
gcc-3.1
binutils-2.12.1
newlib-1.10.0

1. I build the binutils: result OK
mkdir -p builds/m68k/binutils-2.12.1

cd builds/m68k/binutils-2.12.1
../../../binutils-2.12.1/configure --target=m68k-rtems \
    --prefix=/usr/local/cross/m68k

make
make install

2. I added the path (according to the previous --prefix): result OK
setenv PATH 
~/bin/powerpc-apple-darwin:/Users/edo/bin:/usr/local/bin:/usr/bin:/bin:/usr/
local/sbin:/usr/sbin:/sbin:/usr/local/cross/m68k/bin

3. I build the compiler
cd gcc-3.1
ln -s ../newlib-1.10.0/newlib .
ln -s ../newlib-1.10.0/libgloss .
cd ..

cd builds/m68k
mkdir gcc-3.1
cd gcc-3.1
../../../gcc-3.1/configure --target=m68k-rtems \
    --prefix=/usr/local/cross/m68k --with-newlib \
    --with-gnu-as --with-gnu-ld

THESE STEPS TERMINATE CORRECTLY, BUT ...

make

... WORKS FOR A MOMENT AND IT TERMINATES UNSUCCESSFULLY WITH THE FOLLOWING
MESSAGE:

Any ideas to procede withou errors?
