ACKNOWLEDGEMENT
Many thanks to John R. Dunning <jrd@STONY-BROOK.SCRC.Symbolics.COM>
who did the Gnu port, and provided us with all the library sources
etc. All i did was to apply diffs to newer versions, and the configuration
to make the cross compiler fly. Thanks JRD.

This is the README file for the GNU cross development system for atari.

	- Choose a home directory where the cross development system
	  will go. In all subsequent references to this home directory
	  we call it CROSSDIR.

	- Create the subdirectories
		mkdir CROSSDIR/bin CROSSDIR/lib CROSSDIR/include

	- Copy all the '*.h' files that came with the Atari Gnu 1.23
	  distribution into CROSSDIR/include.
	  (remember to use ascii mode to transfer, if you are uploading
	   these files from the atari)
	  (note: included in this distribution is an updated `osbind.h')

	- Copy the files crt0.o and gnu.olb from the Atari distribution
	  into CROSSDIR/lib. (remember to use binary mode to transfer,
	  if you are uploading these files from the atari). Note that
	  once you have made the cross-compiler you can generate these
	  files using the cross-compiler, and copy them to CROSSDIR/lib.
	  I have included cross-compiled versions of these files in
	  the subdirectory `bin-<version>'.

	- the subdirectories are (also see below for more details)
		cross-gas-<version>
		cross-gcc-<version>
		cross-util

	- in each subdirectory there is a file called `XREADME' that
	  contains instructions to compile and install files from that
	  subdirectory.

	- in each subdirectory there is a makefile called `Makefile'
	 that will make the files required. Follow directions in the
	 XREADME file and then type `make install' to make and install
	 files.

	- the subdirectories in this distribution are

	bin-1.30/ atari st executables for gcc v 1.30 and gnu.olb


	cross-gas-1.25/  source for the cross compiler/assembler
			 the same source is used to compile the atari st
	cross-gcc-1.30/  version, once the cross compiler is made.


	gcc-diff-1.28/
	gcc-diff-1.29/ diff files from the corresponding Gnu GCC distribution.
	gcc-diff-1.30/

	cross-lib/     source for the libraries.

	cross-util/    source for the utilities

	gnublurb.txt  jrd blurb.

	- building a new version given a subdirectory
		gcc-diff-<version>

	  - from the corresponding Gnu version copy the files
		cccp.c  combine.c  gcc.c  stddef.h  symout.c toplev.c
	    into a subdirectory cross-gcc-<version>

	  - apply the diffs using larry walls patch
		patch < diff-<version>
		       the file `diff-<version>' is in the gcc-diff-<version>
		       subdirectory.

	  - copy the files
		Makefile Makefile.st XREADME config-atari.h readme.st
		tm-atari.h
	    from gcc-diff-<version> into cross-gcc-<version>.

	  - read XREADME and follow the instructions there to edit
	    the appropriate files.

	  - make the following links
		ln -s config-atari.h config.h
		ln -s tm-atari.h tm.h

	  - link the rest of the files from the Gnu distribution into
	    the cross-gcc-<version> subdirectory. I use the following
	    from tcsh/csh

		foreach i ( <gnu-dist-directory>/* )
		  ln -s $i
		end
            it will give errors for files already existing in the
	    cross-gcc-<version> subdirectory, but will not override
	    them.

	  - make the following (additional) links (if they already exist
	    delete them and make new ones)
		ln -s m68k.md md
		ln -s output-m68k aux-output.c

	  - to make the cross-compiler hit
		make -f Makefile
		make -f Makefile install

	  - once the cross-compiler is made, to make the atari st executables
	    hit
		make -f Makefile.st
