ACKNOWLEDGEMENT
Many thanks to John R. Dunning <[email protected]>
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

'nuff said, have fun,
