Cross GCC for PowerPC and vxWorks

[Jim Benson <jbenson at sextans dot lowell dot edu>]

Hi,

  I am again trying to make a cross compiler for:
host=i686-pc-linux-gnu
target=powerpc-wrs-vxworks

The target is specifically a MPC750 running 
vxWorks 5.4.2 

I have tried a number of binutils versions (this part always works)
and gcc versions from gcc-2.25.3 up to gcc-4.0.2.
My configure line looke like:

 ../gcc-4.0.2/configure --target=$target --host=$host 
--with-headers=/usr/local/wind/target/h --with-cpu=604 
--program-suffix=ppc604 --prefix=$prefix --enable-languages=c,c++

The compiliation continues until:

make[3]: Entering directory

Does anyone have any suggestions on solving this problem?

A similiar problem was responed to on this list by
Dave Korn on Oct 28 2001. His recommendation was to
use gcc-2.95.3 and patches from his website:
http://www.newgcc4vxworks4ppc.cjb.net ...unfortunately
this link doesn't seem to work anymore.
 
All suggestions are greatly appreciated!

Thanks,

Jim
