Hi,
I googled and googled, but I didn't find a solution.
I am trying to build a crosscompiler for ppc. I am using gcc 3.1. I had a look at \
this http://www.kegel.com/xgcc3/ page.

I configured the last cvs like this:
CFLAGS=" -O2 " CPPFLAGS=" -O2 " CC=/opt/gcc-3.1-ppc-cross/bin/powerpc-linux-gcc \
AR=/opt/gcc-3.1-ppc-cross/bin/powerpc-linux-ar \
RANLIB=/opt/gcc-3.1-ppc-cross/bin/powerpc-linux-ranlib \
/usr/src/glibc-cvs/libc/configure --host=powerpc-linux --enable-add-ons=linuxthreads \
--with-headers=/usr/src/kegel.com/linux/include/ --prefix=/opt/gcc-3.1-ppc-cross \
--without-fp make

What CPU types can one specify through the --with-cpu= parmeter?

Here's the error output message:
