Hi Reinhard,

You wanted to run Glaurung as an FRC engine. I have now created a special version with FRC code. This is just a 15 minute hack, and the code is entirely untested (except that the code compiles without errors). Because I don't run Windows, I have no FRC compatible GUI to test it in. Therefore I am not sure how well it plays, or if it works at all.

If you (or anybody else) still want to give it a try, you can download it from this link. Of course there is no Windows binary, but I think the code should compile without changes with the most common Windows C compilers.

Have fun.

Executable compiled with MinGW (probably not very fast):

Tord,

thank you for this! I have made a compile myself witch MS Visual Studio 2003, which succeeded with some warnings. a first test underlined its abilities to perform Fischer castlings.

I've compiled a fast 'Glaurung 024 FRC' build but I'm having
difficulties uploading to my server.

I've sent the file to Alex Schmidt > http://www.uciengines.de/index.html
so hopefully it should be available there very soon.

Hi Jim,

I ended up using Reinhard's executable (Microsoft compiler) instead, but I stole the nice logo above and included it in the download package at my home page. I hope it's OK.

Once again, thanks for your help!

Tord

Sure Tord, that's fine.
I thought the FRC version needed a
different logo.

I've removed my Glaurung download links as
they're on your homepage now.

regards,
Jim.

Depending on the to be analyzed position the compilations could have different performance. It would be interesting to find out, what is performing best in average. My VStudio compilation from some minutes ago is working very well.

They could. In the case of Glaurung FRC, positions before and after castling could perhaps be very different in this respect. I make and unmake castling moves in a very inefficient way. My make_move and unmake_move functions assume that a piece can never move to a square occupied by another piece of the same colour. This is not a problem in normal chess, but it is a problem in FRC. I have handled this in the most simple and inefficient possible way: Whenever a castling move is made or unmade, I recompute my piece lists from scratch. This is probably a rather slow operation.

OK, thanks for sending it to me. I have now updated the Glaurung download again with the new executable. Of course, there is no need to download again for those of you who are not interested in FRC.

Hi Jim

That logo sure looks familiar.

Hi Dave,

Just a classic design, done by some other guy
I can't remember who updated for Glaurung.

Sorry for not giving credit Dave, I wasn't claiming it
was mine. I made an attempt at a logo but it wasn't half
as good as yours.

regards,
Jim.

Hi Jim

No problem. You just saved me some work.
