I've answered this before; I'll append the relevant private message
below [after my .Sig].  

BTW, Chris, have you finished your how-to on setting up a cross
compiler, yet?

Why don't you just ask Archie?  (For `patch', use GNU `patch',
available from every GNU archive, or `patch' from XC which comes with
X11R6.)

Hi Egbert Jan!

Chris Herborth <herborth@53iss6.waterloo.ncr.com> once mentioned that
he was creating a How-To document on setting up a cross compiler
environment.  You might want to get in contact with him -- perhaps he's
finished it already.

For a start, go to your favourite atari archive (atari.archive.umich.edu
has all the stuff) into the ~atari/Gnustuff/Tos directory (or whatever
is appropriate).  There you'll find (almost) everything you need to set up
the cross environment:

update*.zoo:  Grab the latest few of these.  These are patches from
  <bammi@cadence.com> (the main activist in porting GNU stuff to the ST)
  against earlier versions of tools (see below) and against the
  latest original GCC distribution from the FSF.  (You need to be familiar
  with `patch' and `diff' to make use of these.)

gas*.zoo:  The GNU assembler, portet to the ST

util*.zoo:  Binary utilities you'll need (`ar', `ld')

Wrt the C library you have two choices:  The GCC-TOS library and the
MiNT library.  I recommend getting the latter (mntlib*.zoo, mntinc*.zoo).

Now get the latest GCC distribution from some GNU software repository
(e.g., prep.ai.mit.edu:/pub/gnu/gcc-2.5.8.tar.gz) and unpack it.

Here's a roadmap on what to do next:

o decite on where to put the cross compiler.  I use ~/atari/cross-gcc.
  (This is the path you'll have to edit manually into the Makefiles of
  the respective packages.)  In this example, the cross compiler binaries
  will be put into ~/atari/cross-gcc/bin, the libraries into
  ~/atari/cross-gcc/lib, the includes into ~/atari/cross-gcc/include and,
  if you want, the libg++ includes into ~/atari/cross-gcc/g++-inc.

o unpack gas*.zoo;  vi Makefile.dec;  make -f Makefile.cross

o unpack util*.zoo;  vi Makefile.dec;  make -f Makefile.dec

o unpack update36.zoo;  cd gcc-255
  Read the README.TOS and follow the instrucutions in there.  They tell
  you how to patch the original GCC (the gcc-255 patches apply fine on
  the top of gcc-2.5.8)
  vi Makefile.cross;  make -f Makefile.cross

o unpack mntinc*.zoo into your cross directory

o You're now ready to build the C library with your cross environment:
  unpack mntlib*.zoo;  vi Makefile;  make

You're done.  If you want, you can build ST versions of the Assembler/
Utilities/Compiler with the respective Makefile.st supplied, or go on
with other stuff like libg++ (also on atari.archive.umich.edu).

Sorry but I don't have the time to go into more detail now.
Hope that helps, anyway.

Good luck!

Michael
