newbie : cross compiler for powerpc from linux i686 RH7.2


Hi gurus

sorry for this question ( you must have seen it many times ).. but even after going thru the CrossGCC and lists i am having problems getting a cross compiled gcc for powerpc from a linux Red hat 7.2 host..

I dont get any compilation errors during the build steps ( i  have given the steps in the end of this mail ) : 
but when i try to compile a simple printf hello program 
i get a LOT of errors :

-----------------------------------


I think i am screwing up something with the libraries, but anyways here is what i have done..

TOOLS used : 

binutils-2.13.90.0.4.tar  , gcc-2.95.3.tar , newlib-1.9.0.tar 
( planning to use gdb-5.2.1.tar later ) 

Host Details :
Linux  mvtest 2.4.7-10enterprise #1 SMP  i686 unknown
Red Hat 7.2 

target=powerpc-eabi
prefix=/usr/vmore/gnutools/cross-gcc/target


Steps : 

cd /usr/vmore/gnutools/cross-gcc
mkdir src build target test 
cd /usr/vmore/gnutools/cross-gcc/src 
tar -xvf ../../download/binutils-2*  gcc* newlib*

1. Compiling bintuils 
   cd /usr/vmore/gnutools/cross-gcc/build
  ../../src/binutils*/configure --target=$target --prefix=$prefix -v
  make all install 

 	 No compilation errors 

2. Compiling gcc    ( removed libf2c from gcc*/src and linked ln -s ../newlib* newlib in gcc*/src )
   cd /usr/vmore/gnutools/cross-gcc/build
  ../../src/binutils*/configure --target=$target --prefix=$prefix --with-newlib --with-header=/usr/vmore/gnutools/cross-gcc/src/newlib-1.9.0/newlib/libc/include -v
  make cross LANGUAGES="c c++"
make install

	No compilation errors 

3. Test code compilation 

   Added $prefix in my PATH
  A test c program with a single printf in it, 
    powerpc-eabi-gcc hello.c 

   LOT OF ERRORS ..

pls advice 

thanks 
vishwas
