Re: crosscompiler x86->solaris2.8 problems

Hello Kai,

Thank you, thank you, I had been banging my head on the desk for days, 
success at last but not without tears.

Unfortunately, this did not work as you suspected

You are correct, I tried to find it, but have given up for the time being...

Even with verbose and 'bash -x' in configure....

I will raise one tomorrow when I have more time (promise I will)

I manually fixed it using the following (build-gcc is where I build, 
gcc-3.0.4 is where the gcc-3.0.4.tar.bz2 was untared to:

cd ~/build-gcc
../gcc-3.0.4/configure --target=sparc-sun-solaris2.8 --prefix=/sun --verbose 
--with-headers=/sun/sparc-sun-solaris2.8/originals/sys-include 
--with-libs=/sun/sparc-sun-solaris2.8/originals/lib --with-gnu-as 
--with-gnu-ld --enable-threads=solaris --enable-languages=c,c++
cd 
~/build-gcc/sparc-sun-solaris2.8/libstdc++-v3/include/sparc-sun-solaris2.8/bits
ln -sf 
~/gcc-3.0.4/libstdc++-v3/config/os/solaris/solaris2.7/bits/ctype_base.h
ln -sf 
~/gcc-3.0.4/libstdc++-v3/config/os/solaris/solaris2.7/bits/ctype_noninline.h
ln -sf 
~/gcc-3.0.4/libstdc++-v3/config/os/solaris/solaris2.7/bits/os_defines.h
cd ~/build-gcc
make all install

Many thanks for all your help,
I will produce a guide to building "crosscompiler x86->solaris2.8" from 
scratch (a blank home directory) in the next few days and post it to the 
group.

Spencer
