Need help to install a cross compiler for powerpc

[Ian Zhang <hhzhang at yahoo dot com>]

Hi,

I am trying to build a cross compiler for powerpc on
Redhat 6.1.  I tried to follow the FAQ and did
something like this:

1. download 
binutils-2.9.1.tar.gz gcc-core-2.95.2.tar.gz
gcc-g++-2.95.2.tar.gz gdb-4.17.tar.gz
newlib-1.8.2.tar.gz

2.
My current directory is: /dn/cross/
cd /dn/cross
mkdir build-binutils build-gcc build-gdb build-newlib
mkdir install

tar xzvf binutils-2.9.1.tar.gz
tar xzvf gcc-core-2.95.2.tar.gz
tar gcc-g++-2.95.2.tar.gz

3. I try to build a cross-compiler for powerpc.
Following FAQ:

target=powerpc-eabi
prefix=/dn/cross/install

cd build-binutils
../binutils-2.9.1/configure --target=$target
--prefix=$prefix -v
make all install
cd ../build-gcc
../gcc-2.95.2/configure --target=$target
--prefix=$prefix
make all

I got the following error
stdlib.h  No such file or directory.
unistd.h  No such file or directory.

4.  After I read the mailing list.
I copied /usr/include to $prefix/$target/sub-include
I have one question:
Is /usr/include the right source for those header
file?

5. After I rerun the configure and make all, I got the
following error:
checking whether the C compiler
(/dn/cross/build-gcc/gcc/xgcc -B/dn/cross/build-
gcc/gcc/ -B/dn/cross/install/powerpc-eabi/bin/ -g -O2
) works... no

Can anyone help me with those?
Thanks,
