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

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

[revati kadekar]

Hi,
I am newbie to this GNU stuff and also relatively
very raw for UNIX environments, so please bear with
me.
 
I am trying to build the cross compiler for a
embedded system based on powerPC850/860 on a LINUX 7.0
host which has 2.96 GCC native compiler.
 
I have followed the cross GCC FAQ and downloaded all
the right files but still the GCC and newlib builds
fail.I have looked in archives but could not find
answer to my problem.
 
I have downloaded binutils-2.10, GCC-2.95.2,
newlib-1.8.2 and GDB5.0 and have populated them in
build-binutils, build-gcc,build-newlib and build-gdb
directories.
 
 I have specified for target=powerpc-unknown-eabi and
host as i686LINUX.
I have chosen prefix as prefix=/usr/newppc/bin and
have exported this path in PATH.
 
I can build binutils without any problem. But newlib
and GCC failed as shown below.I have tried to build
GCC before newlib as indicated in crossGCC faq. I am
attaching only the tail portion of error log.
GCC builds fine upto a portion and fails for 'as'.
No complaints for headers as seen by some users.But
somehow looks for -mppc instead of
powerpc-unknown-eabi.
We have to use 'newlib' instead of 'glibc' in our
environment for the backward compatibility.
What I am doing wrong ? Please I have to finish this
before Monday, so any help will be really
appreciated.
 
Thanks a bunch,
 RKad

This is covered in the crossgcc FAQ. gcc cannot find the powerpc assembler.
The simplest solution is to use the same --prefix argument when configuring
both binutils and gcc.
