GNU Backgammon for MacOS X

GNU Backgammon (or gnubg for short) is a Free Software Backgammon playing program, licensed under the GNU Public License (GPL).

GNU Backgammon for MacOS X is a full binary version of gnubg, built for MacOS X, and available for download from this website.

Requirements

To install and run GNU Backgammon for MacOS X on your computer, you'll need the following:Note: in a few words: an "X11R6 server" is a graphical user interface system widely used in the UNIX world in which gnubg has been developed -- you could say that X11R6 is to UNIX what Aqua is to MacOS X; by the way, there is no connection between the X in "MacOS X" and the X in "X11R6" :-)

Both XDarwin and Apple's X11 run as standalone applications in the MacOS X environment, mixing Aqua and X11 windows on the same Mac desktop; and both are available as free downloads; if you don't have any X11R6 server installed and running, you will still be able to use GNU Backgammon for MacOS X, but you will get no graphical interface, only text representations of the board and a text command line to input your moves in a terminal window.

How to install GNU Backgammon for MacOS X

Installing GNU Backgammon for MacOS X on your Mac is a three-step process:

Step 1: download and install an X11 server

If you are already running an X11 server, go directly to Step 2 below. Otherwise, download and install one of the following X11R6 servers:
Note: Unless you're already familiar with working in an X11R6 environment, I would recommend your using Apple's X11 rather than XDarwin, as keyboard shortcuts, user windows manipulations and mouse buttons handling are more "Mac-wise" in Apple's X11 than in XDarwin.
Note: You won't be able to use gnubg with XDarwin if you're running Mac OS X 10.3 "Panther"; in that case, use Apple's X11 -- it's included on the Mac OS X 10.3 install CD's.

Step 2: download and install the shared libraries that GNU Backgammon for MacOS X needs

First, download the disk image file below, named sw.dmg, which contains the shared libraries that gnubg needs to run:Note: To prevent your browser from opening the above link in your browser window, trying dragging the link onto your Finder desktop or ctrl-clicking the link and choose "Download link to disk..."

Then, in the Finder, locate the sw.dmg file you have just downloaded and double-click it: it will launch the Disk Copy application and mount the sw volume on your Finder desktop (it will appear as a hard disk).

This volume is the shared libraries folder, that you must copy to the top-level of your Macintosh HD (ie, to /sw, for the UNIX-savvy): to do that, drag the sw volume onto you Macintosh HD while holding down the alt key.

Note: When copying the sw volume to your hard disk, please hold down the alt/option key while dragging the sw icon (a big green plus sign will appear next to your mouse pointer); otherwise, the Finder will create a mere alias to the volume instead of copying its actual contents.

Once copied onto your hard disk, you can unmount the sw volume by dragging it to the Finder Trash (which will then change to an "eject arrow" icon).

Note: Previous users of gnubg for Mac OS X 10.2 upgrading to Mac OS X 10.3: you can't use the previous libraries (the sw folder) as they were built for 10.2 and are incompatible with 10.3; please download the new libraries built for 10.3 and replace your current sw folder with the new one

Step 3: download and install GNU Backgammon for MacOS X

You can choose between four different versions of gnubg for MacOS X:

The most up-to-date version of gnubg for MacOS X 10.3 "Panther"

You will need the gnubg for MacOS X application, its neural net weights (version 0.14) and bearoff databases.

First, download the disk image file below, named gnubg.dmg; then double-click it: it will launch the Disk Utility application and mount the gnubg volume on your Finder desktop; this volume is the gnubg for MacOS X application folder, that you can copy wherever you like onto your Macintosh HD, most preferably in your Applications folder. Once copied onto your hard disk, you can unmount the gnubg volume by dragging it to the Finder Trash (which will then change to an "eject arrow" icon).

Note: When copying the gnubg volume to your hard disk, hold down the alt/option key while dragging the gnubg icon; otherwise, the Finder will create a mere alias to the volume instead of copying its actual contents.

Then, dowload the two ZIP files below, named Weights-0.14.zip and Bearoff.zip; if necessary, double-click them to uncompress them; you will get two folders: Weights-0.14 and Bearoff. These folders contain the neural net weights (two files named gnubg.wd and gnubg.weights) and the bearoff databases (two other files named gnubg_os0.bd and gnubg_ts0.bd); you must copy these files into the gnubg folder you have just created in your Applications folder, on your hard disk.Note: To prevent your browser from opening the above links in your browser window, trying dragging the links onto your Finder desktop or ctrl-clicking the links and choose "Download link to disk..."


The most up-to-date version of gnubg for MacOS X 10.2 "Jaguar"

You will need the gnubg for MacOS X application, its neural net weights (version 0.14) and bearoff databases.

First, download the disk image file below, named gnubg.dmg; then double-click it: it will launch the Disk Copy application and mount the gnubg volume on your Finder desktop; this volume is the gnubg for MacOS X application folder, that you can copy wherever you like onto your Macintosh HD, most preferably in your Applications folder. Once copied onto your hard disk, you can unmount the gnubg volume by dragging it to the Finder Trash (which will then change to an "eject arrow" icon).

The multi-processing version of gnubg for MacOS X 10.2 "Jaguar"

You will need the gnubg for MacOS X application, its neural net weights (version 0.13) and bearoff databases.

This version allows you to take advantage of bi-processor machines to perform rollouts (symmetrical multi-processing, or SMP). It also allows you to connect slave gnubg's to your master gnubg to help compute rollouts faster (distributed processing). Refer to the multi-processing quickstart page to set up multi-processing. As this is a brand new feature, don't hesitate to write to me at gnubgosx@noos.fr if you need help to set up such configurations.

Please note that this version is based on a different development branch than the up-to-date version above, so it lacks many of its most recent features; it also uses the older v0.13 neural net weights.

First, download the zip file below, named gnubg.zip; if necessary, double-click it to uncompress it: you will get a folder named gnubg; this folder is the gnubg for MacOS Xapplication folder, that you can copy wherever you like onto your Macintosh HD, most preferably in your Applications folder.
  • The gnubg for MacOS X 10.2 application zip file: gnubg-multi.zip (1.5 MB) [multi-processing]
Then, dowload the last two zip files below, named weights-0.13.zip and Bearoff.zip; if necessary, double-click them to uncompress them; you will get two folders: Weights-0.13 and Bearoff. These folders contain the neural net weights (two files named gnubg.wd and gnubg.weights) and the bearoff databases (two other files named gnubg_os0.bd and gnubg_ts0.bd); you must copy these files into the gnubg folder you have just created in your Applications folder, on your hard disk.Note: To prevent your browser from opening the above link in your browser window, trying dragging the link onto your Finder desktop or ctrl-clicking the link and choose "Download link to disk..."


The "legacy" version of gnubg for MacOS X 10.2 "Jaguar"

This version was the first released on 09-Apr-2003. It is packed as a single disk image that contains the application, its neural net weights and bearoff databases alltogether. However, it is based on the v0.13 neural nets and lacks several features compared to the above versions (documentation, sound, one-side analysis, temperature map, etc). You should use one of the versions above.

Download the disk image below, named gnubgosx.dmg; then double-clicking it: it will launch the Disk Copy application and mount the gnubgosx volume on your Finder desktop; this volume is the application folder, that you can copy wherever you like onto your Macintosh HD, most preferably in your Applications folder. This folder contains the GNU Backgammon for MacOS X application and its data files (help files, bearoff databases, neural net weights, etc). Once copied onto your hard disk, you can unmount the gnubgsox volume by dragging it to the Finder Trash (which will then change to an "eject arrow" icon).
  • The legacy gnubg for MacOS X 10.2 application, weights and databases disk image: gnubgosx.dmg (9 MB)
Note: To prevent your browser from opening the above link in your browser window, trying dragging the link onto your Finder desktop or ctrl-clicking the link and choose "Download link to disk..."

Note: When copying the gnubgosx volume to your hard disk, hold down the alt key while dragging the gnubgosx icon; otherwise, the Finder will create a mere alias to the volume instead of copying its actual contents.


Note: The application folder gnubg can be installed either in the /Applications directory (the Applications folder that stands at the top level of your Macintosh HD, making it available to all users who have physical access to your Mac), or in your private ~/Applications directory (the Applications folder that stands in your "Home" folder)

Running GNU Backgammon for MacOS X

Once you have installed both an X11R6 server and GNU Backgammon for MacOS X, you can run GNU Backgammon for MacOS X by:
  1. Start your X11R6 server;
  2. Once your X11R6 server is running, in one of its Terminal windows (by default, Apple's X11 opens one such window at startup, and XDarwin opens three), do the following:
    1. If you have installed gnubg in your private Applications folder, type "cd Applications/gnubg" to get into GNU Backgammon for MacOS X's folder, and then type "./gnubg" to run it;
    2. If you have installed gnubg in the global, top-level Applications folder, type "cd /Applications/gnubg" to get into GNU Backgammon for MacOS X's folder, and type "./gnubg" to run it;

Note: Be careful when typing those commands, case matters with MacOS X; so "Applications" is not the same folder as "applications"...
Hint:
Note to previous users: since some version of Mac OS X 10.3.x or X11, you have to add the extra "-w" in the shortcut command line -- read below

To avoid the above running procedure's cumbersome step 2, you can create a quick launch shortcut in Apple's X11 by following the steps below:
  1. In X11, select the Applications -> Customize menu;
  2. In the "X11 Application Menu" window that pops up, click the "Add Item" button;
  3. In the newly created empty entry to the left, type in "gnubg" in the left column, and in the right column type the commands (separated by semi-colons) you would have typed to run GNU Backgammon for MacOS X from the Terminal window; that is:

    cd ~/Applications/gnubg;./gnubg -w

    if you installed gnubg in your private Applications folder, or: cd /Applications/gnubg;./gnubg -w
    if you installed it in the global (top-level) Applications folder.
    Please note the required extra "-w" argument after "./gnubg"
You will then be able to launch GNU Backgammon for MacOS X by merely selecting the "gnubg" item in X11's Applications menu.

Really great code. Great teaching tool, but can be problematic to install. The choice of /sw for libraries is an unfortunate one as it means that there will inevitably be some conflicts with fink (fink.sourceforge.net). This may be there to allow fink users to skip the step of installing the sw image, but I had the following errors:
dyld: ./gnubg can't open library: /sw/lib/libgdkglext-x11-1.0.0.dylib (No such file or directory, errno = 2)
Trace/BPT trap
and
dyld: ./gnubg can't open library: /sw/lib/libgdkglext-x11-1.0.0.dylib (No such file or directory, errno = 2)
Trace/BPT trap
(Actually, I just redefined the links).

This process could be made simple for less capable folks by just putting the /sw directory inside gnubg and using that path. Likewise, I don't understand why the other two folders have to be downloaded separately. It seems that the build process could put these files in the right places in the distribution easy enough.

WARNING WARNING WARNING!

The library /sw installation process TOTALLY fucks
up fink. If you have used fink in the past, and follow
the instructions, a whole bunch of things will no
longer work (plus, gnubg won't work either).

It's totally nuts to distribute the libraries this way.
As the above poster says, put them under the app
somewhere.

second the library libGL.1.2.dylib in /usr/X11R6/lib/ although is the same version as 10.3.9 it is NOT the same library!
so just back up libGL.1.2.dylib and replace it with the osx 10.3.9 version and roberts your mothers brother!
ive done this and it works but is a bit slow to load.
if u have problems with fonts in 10.4 x11 try "sudo fc-cache"

although gnubg is excelent the installation is pretty crap maybe the designers could speak to a mac user first? :)

Here are a few responses to comments that were made:

- Joseph C. Slater and ScrewedUser : true, I should have added a warning to fink users; that'll be done!

- Joseph C. Slater: I have split gnubg into separate downloads (libs, program, and data) because at the time I did that, my ISP offered me very little storage space and I couldn't afford to build several "full" versions of gnubg;

- Slarty and all Tiger users: I've just got Tiger last week, will take a little time to figure what's wrong;

- Keith Hedger and Mac developers: any help welcome! how do I build a Mac program to use fink libs that do not sit in the sw folder? do I have to rebuild all the fink distribution that I intend to use with gnubg into the gnubg folder? fink libs are very difficult to move, because many static paths are built into their code at compile time or stored in config files... again, any help on this topic would be welcome!

el127: X11 is not installed by default, but available as an option from the install CD/DVD;

Olivier:

My sincere thanks to you for providing us such a powerful program for free. Any minor complaints I have with its clunky user interaction are FAR outweighed by my appreciation of its abilities.

I recently upgraded to Tiger and am saddened that I can no longer run gnubg. I hope you can find the time to modify it soon.

Keith Hedger has graciously provided us a workaround for now but I must admit I am not smart enough to follow his directions -- I am not computer-savvy in the slightest and despite his clarifications to me in a private e-mail (thanks Keith) I am still not confident I understand the process sufficiently to carry it out without goofing up something crucial, so I'll just have to wait, I guess.

Again, my sincerest thanks to you (and to Keith).

Given that gnubg has not been updated for Tiger, my work-around has been to maintain OSX 10.3.9 (Panther) on an external hard drive solely to run gnubg. Switching back and forth is still a minor nuisance, and I hope Olivier will find a way to create a Tiger-compatible version. At the very least, he should let us know whether this is likely to happen and, if so, in what time frame.

Okay, happiness for Mac users:

All hail Michael Petch (with Pierre Vaiu getting
lighting-fire-under-butt credit). Michael has re-posted the files for
10.3, and created new 10.4 files. For 10.4, extract this:

http://www2.capp-sysware.co...

...and put it in the root directory of your system's hard drive.

Extract this:

http://www2.capp-sysware.co...

...to wherever (e.g., the Applications folder). Then run X11, select

"Customize Menu..." from the Applications menu, and Add an item. The
Menu Name can be whatever you like, the Command should be the full path
to the gnubg.x11 file from the second download. Don't forget to escape
any spaces with a backslash, e.g. "Macintosh\
HD/Applications/gnubg-0.14.3-tiger/gnubg.x11" Then you can select the
command you just created from the Applications menu and GNU Backgammon
should start up.

10.3 is nearly the same, but has three downloads:

http://www2.capp-sysware.co...
http://www2.capp-sysware.co...
http://www2.capp-sysware.co...

The three files from that third download go in the gnubg-0.14.3-tiger

much faster response than commenting here.

I am beginning to simplify the Mac OS/X install process. I have combined the multiple downloads into one package (DMG). The single download should work.

The prerquisite before using the new Gnubg for Tiger is that you have to install X11 server (It is NOT installed by default unless you select it during installation). You can always install it from the Install CD's after the fact through custom installation. Please see:

http://docs.info.apple.com/...

With the X11 server installed, simply download the latest version from this directory (I will try to update these every month or so).

http://www2.capp-sysware.co...

The latest copy can be found as Gnubg.dmg . Download the file, open the dmg, drag the Gnubg application wherever you wish (Applications folder is always a good choice), and it may also be added to the Dock)

As of April 24th this is new. If you have problems or concerns please contact me at mpetch@capp-sysware.com. As well if you are graphically inclined and can come up with a set of Icons that would look better than the ones I am using - feel free to send send me better ones (They must not be someone elses copyrighted material and will be distributed under the GPL)

Just installed mdpetch's pkg for 10.4 on my Imac g5 2.1G running 10.4.2. with no glitches. While I used to be a unix geek, and occasionally use a terminal, this is the first time I've installed X11 on a mac. Nice not to even have to reboot.

The only slightly weird thing was realizing that gnubg isn't treated as a separate app by the finder GUI, it's a window within X11. I was expect it to work more like Classic apps.

Nice Work Mike, thanks! This is a real service to mac backgammon players. I'd put off installing gnubg because I didn't have time for fiddling, but now it just works.

Howdy All,

Over the past couple month I have been busy with work, and a side project
and I hadn't been able to get back to the umber one Nagging Issue regarding
MAC OS/X on Intel boxes. I have received a tonne of emails (not all I could
respond to) and I'll publish my comments here and at GnuBG.

As many became painfully aware those nice new Shiny Intel mac's do not run
my GnuBG build. The short story is that when I built the 10.4.X binaries I
did not create a universal binary (The equivalent of 2 Executables in one
package - 1 for PowerPC and one for Intel). Because of this OS/X on Intel
tries to run GnuBG via Rosetta (The PPC->Intel instruction converter).

As would happen (Murphy) Gnubg/Rosetta and Xwindows do not play nice.
Xwindows will crash right away when Gnubg is launched. If you run the binary
from the command line you'll find the culprit in the text.

At the time I built the original 10.4.X binary I considered trying my shot
at a Universal Binary. Unfortunately FINK (The collection of open source
libraries and header files) were still not in an acceptable state for INTEL
builds. That apparently is not the case now.

I also have access to an Intel Mac for test purposes. Within the coming
weeks I hope to rebuild a Universal Binary (Intel/PPC builds) to run on
10.4.X. It is generally very easy to build GnuBG with proper Fink libraries
installed. The complex part (and not so automated) is the Fink Relocation
issue (Many who know what this is - I did away with the fixed usage of the
hardcoded /sw directory that is standard practice to many peoples delight).
I have to go through this process again and make sure it works for Intel
builds, and that it works in a Universal Binary.

I'll let everyone know my progress on this.

I can't download the files:
1) The shared libraries disk image: sw.dmg (4.5 MB) For Mac OS X 10.3 "Panther"
2) The gnubg for MacOS X 10.3 application disk image: gnubg.dmg (4.4 MB)
Can Anyone send them via mail?
Thanks

I've long enjoyed Gnubg on my Windows XP machine, but now I have an iMac Intel Duo running OSX10.4. I downloaded the MacOSX version from this site but it refuses to run (The icon appears briefly in the dock and then closes) Is this because the version on your site is not for the Inte Duo?
Thanks

I tried mdpetch's package posted 04/25/06, but it didn't launch. `Gnubg' appears for half a second on the menu line and disappears. I have the iBook G4 with OS 10.4.7 and Apple's X11 server (1.1.3 - XFree86 4.4.0).

Thanks to Michael for making the game available for Tiger. It installed very easily, and runs fine. I didn't have much luck changing the preferences, but I got on well with the game itself - so far, I haven't had much luck winning!

Good news for all Intel Mac users:

Why don't you check out my public's iDisk folder:
Finder --> Go --> iDisk --> Other User's Public Folder --> joerg.picard

Double click on gnubg.dmg and wait a good while until the image is downloaded and mounted. After that , simply drag gnubg into your Application folder in Finder.

This is still a test, so please drop me an email (my iDisk name @mac.com) in tell me whether all features work or not.

Have fun and may the dice be with you.

jpicard,
The program seems to work well. Thanks for your efforts. However, it tends to run slow. The windows version runs about 2.3 times faster. Any way to fix this?

I don't have a PC and therefore can't compare speed. I will have to get with developers of gnubg to find out what could cause this. I've tried a couple of different compiler switches, but that didn't help.

Thankyou for producing the Intel version. So far, works fine on my Macbook.
On the point about speed, one of the things I like about gnubg is that the response speed isn't instantaneous and so it feels more like playing with a real opponent. On that score, I'd say that the Intel version is slightly too fast, and would feel more realistic with a slight lag in it, so you see the computer player's dice, and then there's a gap before the pieces move.

jpicard,
By the way, my speed comparison was done between OSX and Windows running BootCamp, both on the same machine.

Again, thank you.

Dru,
I second your opinion about playing speed, and if GNUBG plays too fast you can slow it down using the options menu. However, when you're trying to do analysis or rollouts you want all the speed you can get.

So close!!!!!

On 10.3, I downloaded the files from the 04/25 post and copied to hard drive. When I double click on gnubg, I see the GNU! But...

1) After it initializes, I get a dialog box saying no neural net weights were found. I extracted the weights files from the tar file in the Panther folder of that link posted on 04/25 (had to go up to parent directory to get to Panther), and put the files directly in the gnubg folder. But the tar file only had 3 files, not four as described. gnubg.wd was the one missing.

2) When I click OK, it then makes a quick sound and then disappears when trying to render the board.

Any ideas? Thanks!

Okay ... I just bought a MacBook Pro and I downloaded jpicard's disc image from his public folder and ...

it all seems to work.

Thanks. However, I've never "recorded" any of my matches at FIBS so I don't know if I'll figure that part out but gnubg seems to launch in the X11 environment just fine.

I have no doubt that GNU Backgammon 2-ply would show a positive result if given enough time vs. any human player in match play.
