powerpc-linux-gnu cross compiler can't be built

[David Ashley]

I'm trying to do
../configure --target=powerpc-linux-gnu
make

It goes for a long time, then fails with this:
mkdir libgcc
mkdir nof
mkdir libgcc/nof
if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

I'm trying to build gcc-3.2.2 as a cross compiler for ppc running on an
x86 system.

My gcc is this version:
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-112.7.1)

I've tried off and on for over a year to build gcc as a cross compiler for
ppc, and it always fails somehow. I've wanted to replace our working compiler
from Montevista's one which is way out of date.

Can anyone offer any advice?

Thanks--
Dave
