BREAKING: Knocking Down The HACIENDA

GNU hackers opened the GHM by revealing the offensive HACIENDA global surveillance program for TWD, and how to knock it down with stealth TCP services! Watch it now! [more]

XBoard

XBoard is a graphical user interface for chess in all its major forms, including international chess, xiangqi (Chinese chess), shogi (Japanese chess) and Makruk, in addition to many minor variants such as Losers Chess, Crazyhouse, Chess960 and Capablanca Chess. It displays a chessboard on the screen, accepts moves made with the mouse, and loads and saves games in Portable Game Notation (PGN). It serves as a front-end for many different chess services, including:

XBoard runs on Unix and Unix-like systems that use the X Window System.

The project also includes a port to MicroSoft-Windows systems called WinBoard.

You can find the downloads for binaries and preconfigured installer packages of Winboard at the Winboard Forum, where yo can also report problems, get help from other WinBoard users or discuss feature requests. Windows builds of development versions or installers for special configuartions can be found at HGM's web page.

Development for Winboard, reporting bugs and any other requests can also be done at the same places as for XBoard (see below).

Downloading XBoard

stable version (4.7.2)

Sources of current stable version can be found on the main GNU ftp server: http://ftp.gnu.org/gnu/xboard/ (via http) and ftp://ftp.gnu.org/gnu/xboard/ (via ftp). It can also be found on one of the mirrors of ftp.gnu.org; please use a mirror if possible.

Precompiled versions are available for openSUSE and debian-sid (if you know of other distribution that package it, please let us know).

development version

We regularly do so called 'developer releases', which include the newest and the latest we are working on. If you want to help us test, or just want to use the new features, you might prefer to use those over the stable version.

At the Open Build Server we provide packages that can be installed in parallel to the normal xboard version. To do this the programs are renamed to xboardnext (latest from the v4.7.x branch in git) and xboardgit (latest version from the master branch in git). Packages are available for: Debian 6.0, Fedora 17/18, RedHat RHEL 6, opensuse 12.1/12.2/12.3/Tumbleweed/Factory, Centos 6, Arch, Ubunutu 10.04/12.04/12.10. These packages are generated automatically and are for testing purposes only. Please let us know if you have any problems related to XBoard or package dependencies.

Windows builds of development version can often be found at HGM's web page.

Furthermore we provide development versions (tagged commits in git):

How to build the development version
git version

The git repository is available on Savannah. All branches can be viewed there. The web page also provides tar-balls of all tagged versions, these tar-balls are different from the ones that you can download from the ftp-server and you will need to run ./autogen.sh on them as described below.

If you want to get a copy of the repository you can clone it using the command "git clone http://git.savannah.gnu.org/r/xboard.git". For more information on how to use git, please visit the git home page.

After cloning the git-repository or downloading and unpacking a snapshot tar-ball from the git repository, run ./autogen.sh, ./configure and then make and make install.

tar-balls (from the ftp-server)

Unpack the tar ball and do ./configure followed by make and make install.

For development sources and other information, please see the XBoard project page at savannah.gnu.org.

archive

You can also find an archive of old versions on the ftp server.

Documentation

The official manual page for XBoard is available online, as is documentation for most GNU software. This discusses every feature XBoard has in detail. You may also find this information on your local system by running info xboard or man xboard, or by looking at /usr/doc/xboard/, /usr/local/doc/xboard/, or similar directories on your system.

There now also exists an XBoard User Guide, which only presents the main features in a more pedestrian way. This would be an excellent starting point if you are a novice XBoard user. If you have prior experience with XBoard, but just want to know what new features have been added since the version you were used to, the pages in the What's New section would be the place to go.

A description of the Chess Engine Communication Protocol used by XBoard to communicate with Chess Engines can be found here.

These are screenshots taken from version 4.4.0 (click to enlarge).

Help needed

It would be great if people would like to help in the developing process. We can use all kinds of help, from people who just use the software and have a feature request (send them to developer mailing list), to people who can update/check the documentation and especially people who test development versions (send problems to the developer mailing list). Have a look at the following list in case you are interested:

Translators

We added support for different languages to XBoard and need people to translate it. The translation is handled by the translation project. You can check on the current status and how to join the translation project.

Testers

We are always looking for people who are willing to test the latest new features and give us feedback or new ideas. If you are interested, please send an email to our list at <xboard-devel@gnu.org> or just try out the program and reports bugs either to the email list or to the bug-tracker (see below for links).

GTK developer needed

We are also working on merging Winboard and XBoard back into one version using a cross platform GTK-front end. This will help us clean up the code and make things like internationalization easier. We made some progress, if you know want to help out there are still lots of things waiting to be done. Email the mailing list for more information.

EPD test-suite capability

A sort of match mode where one engine automatically does a number of 'games', (using a position file filled with EPDs as starting positions), except that each 'game' lasts only for one move, and the 'result' is then computed by XBoard depending on if this move was the correct solution specified in the EPD.

Multi-board ICS mode

Implement a slave mode where XBoard forks itself, connecting a pipe between what normally would be the ICS socket of the child, and a new output channel of the parent, so that the parent can forward board and move lists belonging to a specific game to the slave dedicated to display it.

Update the documentation

The documentation could need some updates. In our effort to merge Winboard and XBoard back together, we also want to merge the RTF file back into the XBoard texinfo file. This will take some effort though, since the two versions still differ in several areas and this would need to be highlighted. The benefit would be though that we could prepare a much better and up to date Windows documentation.

Update the webpage

The content of the webpage could be updated with screenshots from the latest version. We also have a new tutorial that could be integrated. The webpage should also be integrated with git, so that all developers have access to it.

Mailing Lists and Discussion Forums

mailing lists

XBoard has two mailing lists: <bug-xboard@gnu.org> and <xboard-devel@gnu.org>.

The main discussion list is <xboard-devel@gnu.org>, and is used to discuss most aspects of XBoard, including development and enhancement requests. Please send bug reports to <bug-xboard@gnu.org>.

Announcements about XBoard and most other GNU software are made on <info-gnu@gnu.org>.

To subscribe to these or any GNU mailing lists, please send an empty mail with a Subject: header of just subscribe to the relevant -request list. For example, to subscribe yourself to the GNU announcement list, you would send mail to <info-gnu-request@gnu.org>. Or you can use the mailing list web interface.

discussion forums

A very active forum is the WinBoard Forum (where our current main developer HGM can be found).

Reporting Bugs and Requesting New Features

If you think you found a bug, please check the bugtracker for open and already closed bugs. If you found a new bug, please, file a bug-report either via our bug-related email list or in the bugtracker.

For feature requests, please use our mailinglist: <xboard-devel@gnu.org>.

Please remember that development of XBoard, and GNU in general, is a volunteer effort, and you also can contribute. For information, please read How to help GNU.
