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
