Now comes the easier part, compiling the KallistiOS
Operating System which Dan Potter wrote for the Dreamcast.
(libdream is no longer supported and KOS now offers half-way
compatible API's)
- Visit Dan
Potters DCDEV or the KOS
Sourceforge page and download the latest KOS sources
- Copy the tarball into your Cygwin tree and unpack it
tar zxf kos-1.1.5.tar.gz
- Make a small change to the kos-1.1.5/utils/genromfs/genromfs.c
sourcecode.
(this is not needed anymore from 1.1.7 on and if you
use CVS-KOS)
Just add the following line at the top of the source:
#define _WIN32
- Now copy the file kos-1.1.x/doc/environ-dc.sh.sample
to kos-1.1.x/ and change the file to reflect your
install patch for the KOS sources
- Run this shell-script with
. ./environ-dc.sh
(the single dot in front is extremely important since
otherwise the environment variables will be cleared after
the script finishes)
- Now type
make
and everything should compile, including the examples.
GETTING CVS-KOS:
In order to get the KallistiOS sources from the CVS repository
just open up a Bash-Shell, browse to where you want
your KOS to reside and execute the following two commands:
cvs -d:pserver:anonymous@cvs.cadcdev.sourceforge.net:/cvsroot/cadcdev
login
cvs -z3 -d:pserver:anonymous@cvs.cadcdev.sourceforge.net:/cvsroot/cadcdev
co kos
(NOTE: You have to have CVS installed
from the Cygwin Installer in order to use it. If the Bash
does not find CVS install the corresponding Cygwin package)
All the notes for the release versions of KOS also apply
to CVS ! But you have to make one additional change to the
Makefile in the KOS root directory.
Just comment out the following line (by adding a #
in front of it):
cp lib-release/libm.a lib/
(This is needed because the binary KOS released come
with a precomiled libm. If you followed my tutorials you
already compiled your own when compiling newlib !!!)
HINT:
Now would be a good time to add the following line to your
.BASHRC (which can be found in your cygwin home
directory, normally /home/username .If this file
does not exist yet just create it or alternatively put the
line in /etc/profile) to be able to use KOS whenever
you start your Cygwin shell.
. ./kos-1.1.3/environ-dc.sh
(The single dot in front of the command is essential
since otherwise the EXPORTS will only be valid within the
shellscript)
You are now ready to write your own programs/demos/games
for the Dreamcast.
