Re: x86 redhat ppc-32-elf gcc build failure

Hello,Vermeulen Jan:
   Thanks for your help.the link is valuable for me.
   I  solved the problem following it's instruction.
   The problem is that I missed some parameter in configure gcc process.After I
added the --with-headers=dir and --with-newlib parameter.It runs good.
below is my operation:
cd /home/foo
target=ppc-32-elf
prefix=/bar
i=$prefix/bin
cd build-binutils
../binutils-2.9.1/configure --target=$target --prefix=$prefix -v
make all install
# Configure, build and install gcc
cd ../build-gcc
../gcc-2.8.1/configure --target=$target --prefix=$prefix
--with-headers=/home/foo/newlib-1.8.1/newlib/libc/include --with-newlib -v
make all install

# Configure, build and install newlib
cd ../build-newlib
../newlib-1.8.1/configure --target=$target --prefix=$prefix -v
make all install \
        CC_FOR_TARGET=$i/gcc \
        AS_FOR_TARGET=$i/${target}-as \
        LD_FOR_TARGET=$i/${target}-ld \
        AR_FOR_TARGET=$i/${target}-ar \
        RANLIB_FOR_TARGET=$i/${target}-ranlib
