I think this is the right script.  If you have any problems, let me know.

I started by copying the contents of /usr/lib and /usr/include from a sun
box into a network accessible directory.  I then fixed all the links that
got messed up coping the files over and deleted any that were obviously
unneeded (erring on the side of leaving them in).  The directories that
I used were /tools/sw_build/native_SunOS/lib and
/tools/sw_build/native_SunOS/include respectively.  Then I ran the
following script:

# start script

#!/bin/sh

# Stop if errors occur along the way.
set -e

export DATE=20010720

export TARGET=sparc-sun-solaris2.7
export PREFIX=/tools/sw_build/host_Linux/$TARGET/Build-$DATE
export MACHINE=SunOS

export BINUTILS=binutils-2.10.1
export GCC=gcc-2.95.3
cd /tools/src/build/host_Linux/$TARGET

mkdir -p build_$BINUTILS
cd build_$BINUTILS
../$BINUTILS/configure --target=$TARGET --prefix=$PREFIX --disable-shared
-v |
tee config.log
make all install | tee make.log
cd ..

export PATH=$PATH:${PREFIX}/bin

mkdir -p build_$GCC
cd build_$GCC
../$GCC/configure --target=$TARGET --prefix=$PREFIX --disable-shared
--with-headers=/tools/sw_build/native_$MACHINE/include
--with-libs=/tools/sw_build/native_$MACHINE/lib --with-gnu-ld
--with-gnu-as  -v  | tee config.log
make all install | tee make.log
cd ..

# end script

Hope this is useful.  The directory structure I used is more messy than it
needs to be (political reasons) but that's the basic procedure.

I think that this should work.  I have since moved on to getting 3.0 to
work (successfully!!!) but it is more difficult because I hacked up the
source tree to fix a configure bug.


Good luck!
