You can compile Kawa from the source distribution. Alternatively, you can install the pre-compiled binary distribution.
You can get Kawa sources and binaries from the Kawa ftp site ftp://ftp.gnu.org/pub/gnu/kawa/, or from a mirror site.
The latest release of the Kawa source code is ftp://ftp.gnu.org/pub/gnu/kawa/kawa-1.8.tar.gz. The same sources are available as a zip file ftp://ftp.gnu.org/pub/gnu/kawa/kawa-1.8-src.zip.
A ready-to-run .jar archive of the pre-compiled classes is in
ftp://ftp.gnu.org/pub/gnu/kawa/kawa-1.8.jar.
Kawa was recently changed to use Subversion (svn) instead of CVS.
The Kawa sources are managed using a Subversion (svn) repository. If you want the very latest version grab an svn client, and then check out the source using this command:
svn -q checkout svn://sourceware.org/svn/kawa/trunk kawa
If you're beyond a firewall or HTTP proxy, you can edit
http-proxy-host and http-proxy-port
in ~/.subversion/servers as described
here,.
and then do:
svn -q checkout http://sourceware.org/svn/kawa/trunk kawa
Once you have it checked out, you can keep it up-to-date with svn update.
You can also browse the svn archive via viewvc.
