Error in building GCC 2.95.2 cross compiler for powerpc-unknown-eabi on LINUX 7.0

[revati kadekar]

Thanks for the earlier reply. I am using same --prefix
for building both binutils and GCC.
I didn't have the write permission on my /usr .
So I used a new prefix as /bar under my home
directory.
With that binutils passed installation but GCC is
still failing.
This is my setup:
cd /home/rkadekar
host=LINUX
target=powerpc-unknown-eabi
prefix=/bar
i=$prefix/bin
cd build-binutils
../binutils-2.10/configure --target=$target
--prefix=$prefix -v
make all install
This step passed
 
#Configure, build and install gcc
cd ../build-gcc
../gcc-2.95.2/configure --target=$target
--prefix=$prefix -v
make all

Why is it finding some include files and failing for
others ?
locate these files yielded the result shown below.
locate stdio.h
/home/rkadekar/gcc-2.95.2/libio/dbz/stdio.h
/home/rkadekar/gcc-2.95.2/libio/iostdio.h
/home/rkadekar/gcc-2.95.2/libio/stdio/stdio.h
/home/rkadekar/newlib-1.8.2/newlib/libc/include/stdio.h
/usr/include/bits/stdio.h
/usr/include/stdio.h
/usr/lib/bcc/include/stdio.h
Which one is it looking for ?
Any help is appreciated.

Thanks,
RK
