Re: cross-compiling problems

["Stephen Biggs" <s dot biggs at softier dot com>]

Maybe try configuring by adding the option "--disable-threads" both in the binutils and gcc?  Did 
you use --with-newlib and --enable-multilib all the way through the configure stages?  I don't know 
if multilib is necessary for the sparc, but it probably wouldn't hurt... if not, leave out that 
option.

One way to try it first is to do the link below to newlib, and try a full build of gcc without the -
-disable-threads.  If that doesn't work, then rebuild binutils and gcc both with --disable-threads.

First, I built binutils. 

$ cd build-binutils
$ ../binutils-2.13/configure --prefix=/root/crosser/sparc --with-newlib --target=sparc-sun-
solaris2.5 --enable-multilib
$ make all install
$ cd ..

The way I got gcc to build was to add a symbolic link in the top level gcc directory to newlib:

$ ln -s newlib-1.10.0/newlib gcc-2.95.3/newlib

I was then able to build a full compiler without the intermediate step of making a bootstrap 
compiler.

$ cd build-gcc
$ ../gcc-2.95.3/configure --prefix=/root/crosser/sparc  --target=sparc-sun-solaris2.5 --with-newlib 
--enable-multilib
$ make all install
