OK, I've gotten not much feedback, whch is depressing, but I'll try again.
My goal: build a cross-gcc for ppc->i386
The steps below work fine on a i386 box, but fail when I try to duplicate
them on a ppc iMac.
# configure/build binutils
cd binutils-2.13.2.1
./configure --prefix=/home/jeff/crosscomp --target=i386-linux
--host=powerpc-linux
make
make install
mkdir /home/crosscomp/include
cd /home/crosscomp/include
cp -ai /usr/include/* .
rm -rf asm
rm -rf linux
cp -ai /usr/src/linux/include/i386-asm asm
cp -ai /usr/src/linux/include/linux .
# configure/build bootstrap gcc
export TPATH=$PATH
export PATH=/home/jeff/crosscomp/bin:$PATH
cd gcc-3.2.2
./configure --prefix=/home/jeff/crosscomp \
--host=powerpc-linux --target=i386-linux \
--with-headers=/home/jeff/crosscomp/include \
--disable-shared --disable-nls --enable-languages=c
make
make install
export PATH=$TPATH
export AR=/home/jeff/crosscomp/i386-linux/bin/ar
export CC=/home/jeff/crosscomp/i386-linux/bin/gcc
export RANLIB=/home/jeff/crosscomp/i386-linux/bin/ranlib
#configure/build glibc
mkdir /home/jeff/build-glibc
cd /home/jeff/build-glibc
/home/jeff/glibc-2.3.1/configure --prefix=/home/jeff/crosscomp \
--host=i386-linux --build=powerpc-linux --enable-add-ons \
--with-headers=/home/jeff/crosscomp/include \
--with-libs=/home/jeff/crosscomp/lib --enable-shared --disable-nls \
--enable-threads=posix
make
make install
export AR=
export CC=
export RANLIB=
# configure/build full gcc
export PATH=/home/jeff/crosscomp/bin:$PATH
sudo rm -rf gcc-3.2.2
tar xvfz crosssrc/gcc-3.2.2.tar.gz
cd gcc-3.2.2
./configure --host=powerpc-linux \
--build=powerpc-linux --target=i386-linux \
--prefix=/home/jeff/crosscomp \
--with-headers=/home/jeff/crosscomp/include \
--with-libs=/home/jeff/crosscomp/lib --enable-shared --disable-nls \
--enable-add-ons --enable-threads=posix --enable-languages=c,c++
make
make install
This final step (which works on a i386 box) fails on the ppc
