Re: --target=powerpc-unknown-elf, binutils-2.15?

Hi,

thanks for your hint.  Sorry, i mistyped it in this mail, but
i gave the same options to binutils and gcc.

I configured binutils:

# This directory was configured as follows,
# on host schleim:
#
# ../binutils-2.15/configure  --target=powerpc-unknown-elf \
# --prefix=/opt/powerpc-unknown-elf

With this little script i try to build gcc-core (The binutils for ppc are
in the PATH):

#! /bin/bash

[ -d bgcc ] && rm -rf bgcc
mkdir bgcc
cd bgcc
../gcc-3.4.1/configure \
--target=powerpc-unknown-elf \
--prefix=/opt/powerpc-linux


Still, i get this message:

Thanks for any hints,
