binutils compiled and installed fine. (seperatley, due to HD space limitations)

However, egcs still won't compile.

After building and installing the binutils, I entered the egcs-bin
directory I created, did a '../egcs-1.1.2/configure --target=ppc-linux
--with-cpu=603e --with-headers=/usr/include', 'make clean' and 'make cross'
and got this:

Well, I just extracted the libraries out of the ppc libc6-dev 2.1.1-12.3
debian package, and pointed the configure script at them. They were copied
into the appropriate place etc and it looks as though all went well.

I did a 'make cross' and it died at the same spot with the same error. Fudge.

Should I obtain and add the c++ libs and try again, or am I dealing with a
different problem?

I certainly hope the configuration script isn't trying to compile something
with the cross-gcc and then run it to see if it works, as doing so wouldn't
be terribly productive.

TIA - Tony

You need to provide target libraries (ie libc) so that the target configure

You should almost never specify the host.  Let configure guess.

xgcc is using the wrong as.  This may be a gcc Makefile bug that I have
seen before.  It works best if you do a one tree build with binutils in
the gcc tree.  See http://www.objsw.com/CrossGCC/ for details.

can do.

last time I let it guess, it thought I was running _on_ ppc-linux, likely
because of the earlier option.

I'd like to do that, but my budget doesn't include much HD space. I assumed
from it's documentation that the debian binutils-multiarch package included
a version of as/ar/ld and whatnot that is capable of handling files for all
the architectures. I should probably double-check that, as it would be easy
to leave out as.

I'll see if I can free up some HD space and install the binutils tree.

Thanks - Tony
