Expert help required with building linux hosted crossGCC targeting MPC860


Hello,

I am trying to create a cross compiler from gcc 2.95.2 sources.
The cross compiler is to be hosted on a linux x86 (P3 450) PC but I want
it to
target an embedded system with a Motorola MPC850 (860 for all intents &
purposes).

I set up the following directories:

/usr/local/cross-gcc/src    # all source code tar -zxvf unpacked here
/usr/local/cross-gcc/target # This is the prefix dir

# The following dirs are from where I call configure and make
/usr/local/cross-gcc/build/{binutils,gcc,gdb,newlib}


Then I built binutils-2.9.5.0.24:

cd /usr/local/cross-gcc/src
target=powerpc-eabi
prefix=/usr/local/cross-gcc/target
cd /usr/local/cross-gcc/build/binutils
../../src/binutils-2.9.5.0.24/configure --target=$target
--prefix=$prefix -v
make all install

binutils built just fine.

Then I try to build gcc-2.95.2:

cd /usr/local/cross-gcc/src/gcc-2.95.2

Following the advice of an article by Bill Gatliff on www.embedded.com I
did
this:
rm -rf libf2c
ln -s ../newlib-1.8.2/newlib newlib

Then off to my build dir:
cd /usr/local/cross-gcc/build/gcc
../../src/gcc-2.95.2/configure --target=$target --prefix=$prefix
--with-newlib \
--with-headers=/usr/local/cross-gcc/src/newlib-1.8.2/newlib/libc/include
\
--with-cpu=860 -v

make cross LANGUAGES="c c++" install

It then spits out build rules an bits of shell script for about 5 to 6
minutes before stopping with the following final few lines of output:-

----------------------output ends-----------------------------
It seems like gas is called with an invalid option but I've been
wondering whether it's barfing on one of the input files with
-ppc in its name.  I don't know though, hence this email. :-)

The only thing extra that I can think to mention is that my operating
system is RedHat Linux version 6.1 and my native GCC is version 2.91.66.

I apologise for the length of this problem description but I thought
it necessary to give as complete a picture as possible in order to get
the best possible help.

I have also examined the crossGCC FAQ as well as the GCC manual &
installation instructions.  I have also search through some mail
archives but haven't found anything that has been of any help (yet).

I would really appreciate some help to get my cross compiler built.

Please send responses to jgl@one.net.au  I am using hotmail in an
attempt to bypass the mail servers spam protection.

cheers & thanks in advance,

Jeff
