Instructions

Both Jazz and Sjaak are distributed under the terms of the GNU General Public Licence. Both programs should work properly on any flavour of Linux, as well as Mac OS X and Windows. I'll provide executables for as many systems as I can below, but in case these don't work I'll also include detailed descriptions for how to compile the source code.

Prerequisites

If you wish to compile the programs from source code you will need:

• A C99 compiler, such as GCC. Possible alternatives are Clang or the Intel C/C++ compiler, but these have not been tested. The Microsoft compiler does not have very good C99 support and will probably not work. In Windows, I've got it to compile using the MinGW compiler (install using the automated installer) in the past, but these days I use a cross-compiler from Linux.
• GNU Make. This probably comes with the compiler (strictly speaking, this is optional, since you could use another build system, like XCode on a Mac; see the next step)
• CMake, a cross-platform configuration tool and Makefile generator.
• Allegro 5 (optional). You don't need this unless you want to compile the native GUI for Jazz and Sjaak (disabled by default).

Compiling

Download and unpack the source archive in a location of your choice. Next, you'll need to prepare the package for compilation using CMake. It is recommended to do a so-called "out-of-source" build, so all generated files are in a separate directory, leaving the source directory clean. From a terminal, type:

$ cd <source-dir>
$ mkdir Build
$ cd Build
$ cmake ..

For <source-dir>, substitute the directory where you unpacked the source code. If you want to change some of the default options, you can do so easily with the command line program ccmake, or with the CMake GUI.

After the source has been prepared, run make to compile the program(s).

For Jazz you have the choice between the XBoard interface (xbjazz) and the UCI interface (ucijazz). The XBoard interface for Sjaak is called xsjaak, for Leonidas it is xleo.
