Trouble building gcc 1.8.1 cross complier...

["Don Post" <post@blaze-net.com>]

Howdy,

I have had no luck trying to build a m68k cross compiler hosted
either on a Sparc running Solaris 2.6 or my Intel box running Linux
Redhat 5.0 distribution.

The native compiler on both systems has been upgraded to version 1.8.1.

Here are the versions of what I plan on using:

    binutils 1.9.1
    gcc 1.8.1
    newlib 1.8.1
    rtems 3.6.0

I have followed the crossgcc-FAQ (version 0.8.1) and I have the following
directory structure:

/homes/post/binutils/binutils/binmake
                           ../binutils-2.9.1

/homes/post/binutils/binutils/gccmake
                           ../gcc-1.8.1

/homes/post/m68k


I configured and built successfully binutils using the following commands
from the /homes/post/binutils/binmake directory:





 ../binutils-2.9.1/configure --target=m68k-coff --prefix=/homes/post/m68k -v
     make all install

After that completed successfully, I then attempted to build the cross gcc
compiler. When I build it using:





 ../binutils-2.9.1/configure --target=m68k-coff --prefix=/homes/post/m68k -v
     make all install

is get the following error:

------------------
touch objc-headers
./xgcc -B./ -dumpspecs > tmp-specs
mv tmp-specs specs
if [ -f libgcc2.ready ] ; then \
        true; \
else \
        touch libgcc2.ready; \
fi
echo "" > tmp-runtime
echo "/* This file is automatically generated */" >objc/runtime-info.h

If I build instead using:

 make LANGUAGES="c c++"

the build fails with:

Any ideas what I could be doing wrong??
