WebOS Chess (real Chess)

[rboatright]

In the homebrew app feed, you will soon find Mathias Eck's new WebOS Chess. This is in no way related to the previous javascript chess engines. It's a real binary chess app running either the StockFish or Glaurung chess engines with a javascript user interface.

http://www.precentral.net/homebrew-apps/advanced-chess

Source code is on the Webos-Internals git repository.

Support and questions here.





YOU MUST INSTALL THE PDK for advanced chess to run.

The libraries are not yet built into the OS.

Advanced Chess is a chess app by Mathias Eck. It is currently using the Stockfish or Glaurung chess engines, and has a compressed opening book. This is in no way related to the other javascript "Pre Chess" app. It's a real binary chess engine with a javascript user interface. Source code can be found on the webos-internals git site. This app requires an advanced installer (Preware or WebOS Quick Install ) It will not run if you use the SDK installer, since the "post install" scripts do not get run.

0.0.7 now drops the download size to less than 0.5 meg.

If you want to download the 10 meg opening book, you can do so from the prefs page.

YOU MUST INSTALL THE PDK for advanced chess to run.

The libraries are not yet built into the OS.

NOTE

A future release of webOS (something after 1.4.1) will have the PDK stuff already installed.

However, PDK beta testers have learned that the future version of webos changes the names of the functions one calls in the PDK.

Therefore, when that webOS update comes out, we will have to (quickly) post a new version of Chess for the new version of the PDK files.

This version will break until you update.

Nothing we can do to avoid that. If you choose to wait I will understand.

This sounds great - but I am having trouble:

I've installed via preware, but I can't get beyond the first move: I make my move, and then - nothing.

The settings are default - pre plays black, 4 sec move time.

Have I missed something obvious?

You MUST install the pdk for advanced chess to run as of May 2010. The current version of webOS does not have the PDK libraries in it yet.

So, for now, you must install the PDK or the engine won't start.

To run PDK apps it is necessary to install the PDK libaries.For that you have to enable developer-mode download the PalmPDK.exe and start the pdk-device-install.bat script.

(Hopefully the libaries will part of the 1.4.5 WebOS).

After this, the start of prechess should launch to plugins:

I was wondering... Would I have to then remove this pdk library before an update. Will there b difficulty settings? Trainers?

Would I have to then remove this pdk library before an update

I had no problems by the update from 1.4.0 to 1.4.1.

Will there b difficulty settings? Trainers?

At the moment there are only time per move settings.
And i think that on the 2 second option the ELO is
still about 1800 ELO and the real thinking time is lower then
0.5 seconds.
To have e weaker opponent i will integrate later fruit and toga-engine.

Trainers are not planed yet.

Mathias

Any screenshots of the new chess engine?

So you have to doctor to 1.4.0 to install the PDK?

So you have to doctor to 1.4.0 to install the PDK?

The script "pdk-device-install.bat" included in the PalmPDK.exe
will work also with 1.4.1.

The coming 1.4.5 will have the libaries out of the box.
The version will jump to 0.1.0 and will not backward
compatible.

Mathias

What about the Mac? Can't run .exe or .bat apps.

[rboatright]

The pdk comes with mac install instructions.

Visit the site linked above.

Screenshots are on the listing of the app at http://www.precentral.net/homebrew-apps/advanced-chess

Thanks. But I already tried to follow those instructions and got this, even though I'm running webOS 1.4.1.1 (xxx means my specific prompt info):


xxx:bin xxx$ ./pdk-device-install install


Found connected device: Palm Pre

ERROR: Only devices with Palm webOS 1.4.0 are supported!

Run Updates app on device to update to Palm webOS 1.4.0, or
go to http://www.palm.com/rom to get webOS Doctor 1.4.0.

[rboatright]

How very odd. That shouldn't have happened.

[freibauer]

ERROR: Only devices with Palm webOS 1.4.0 are supported!

Inside the pdk-device-install script there
is a hardcoded comparison with the string

== "Palm webOS 1.4."

you can modify this to "1.4.1.1"
On my device the installed PDK-Libaries are
working fine with version 1.4.1. .

oops. double post

[lawtalkinguy]

I downloaded and installed the PDK onto my desktop. Now, how do I load it up on the pre? Is there a step by step for those of us who are not programmers?

[freibauer]

Installation description :

PDK - Preparing the Device for Development - Palm Developer Center

- Enable Developer Mode
- Install "Open SSH" + "Open SSH Server" via preware
- Check ssh with putty (usb-connected,localhost,10022)
- Execute: "pdk-device-install.bat install"

[Pulp]

- Enable Developer Mode
- Attach USB-cable
- Execute: "pdk-device-install.bat install"
works aswell

I'm very much afraid this is a stupid question, but I'm obviously missing something here: where do I find the PalmPDK.exe file? I thought it might be included with the chess pkg, but I don't see it, and I've searched PreCentral to no avail.
