Chess Engine/frontend

[pungipungi]

I wondered if anyone uses a chess engine under gpe. So far I didn't find any hint  ...

After two weeks setting up my bitbake/compile environment and getting the first gpe program compiled, I've seen that also the fltk lib is available.

For personal tests I did a little port of my old agenda frontend  and recompiled gnuchess for the zaurus.

Beware the colours are much nicer on the zaurus ....

If there is any interest I will publish the sources ....

How simple is the compile? Put together a .bb file for it and add it to OE,

It's based on the fltk-lib as provided by the 3.5.3 development tree.

The GUI is very simple. It's only one simple make file, one source code file,  a header file , some pixmaps ...

The only pitty is that I'm not used to writing bb files. I've tried one very simple for gnuchess (without patches) and it seems to work. I will try to write another one for the frontend soon ...

By the way, in older versions there was a gnuchess package available. But I can't find a bb file. Is this caused by switching to oe?

At the moment I've transfered an ipkg to my webpage. It includes an extra set of X libraries since my production for 3.5.3 complains for a missing symbol when using it with the standard X11 lib delivered with 3.5.3.
I haven't checked yet if my X11 libs can be used with all the other gpe and X11 stuff delivered with 3.5.3.

In older versions of what? OpenZaurus? If you mean that gnuchess was available before OE was used, then perhaps it simply a case of no-one having added it. There are a couple of chess programs in there already - phalanx and knights, though it looks like both are for Opie.

Hmm, this is an fltk error I assume? I think this is because 3.5.3 uses diet-x11 by default. I ran into this problem when I was messing about with Giac. If you specify that you want to use the full-fat version of the X11 libs then this will go away. A more long term solution is to see what fltk needs the full-fat libs for and see if it can be patched to remove the requirement and allow it to use diet-x11.

Yes openzaurus but don't know which version ...
knights is definitive a qt application.
phalanx defines as section opie/libs but I'm not sure if it is really a qt application since it's also used as chess engine for knights (which acts as frontend).

Uuups ... good point I have to check which libraries fltk-chess uses at the moment ...
(at least I was glad to have a running bitbake based building environment after struggling around two weeks with to less memory, wrong bitbake versions, missing archives, .... )

Good news concerning bb files. I've managed to make a very raw dirty version for gnuchess and another for my fltk-chess frontend. So I'm on the way ...

[pungipungi]

I've placed 2 archives and the bb files for gnuchess and the fltk-chess frontend on my Webpage.

Not sure if the bb files are already correct. They worked in my local configuration (with archives loaded to ~/sources). Maybe somebody can try it .....


I edited your post as the URL was wrong - Lardman
Thanks ...

You were right. I've changed fltk a bit to make it run also with the diet-X11 libs. Therefore I've eliminated the XOpenIM call which is not part of diet-x11. But it works nevertheless ...
I've placed the result (based on koen's feed on)

Have they been added in? (not at uni so I can't look at my dev machine atm)

If not, and you're happy to maintain them, create a bug on the bug-tracker and set the type as 'enhancement' and give an explanantion of what you're providing & attach the .bbs

I changed the .bbs a bit and put them at http://dominion.kabel.utwente.nl/koen/OE/

Do you have a patch for fltk? I think that would be a good addition to the fltk in OE
