Linux port of newer versions of TogaII

Hi ,
I ported Toga 14b5c and Toga 142JD back to linux
. See
http://emis.uhasselt.be/~webby/Toga/
I think these sources will still compile under windows. Perhaps someone can verify this.
The porting was not hard. The windows thread api and the posix thread api are more
or less equivalent.
Regards,
Michel

Hey thanks! They compile fine on Mac OS X.
How do you set the number of threads? They seem to default to 2.

There is a line
const int NumberThreads = 2;
in search.h.
You can change it.

Could you stick your build of 1.4 for the Mac somewhere public? The last version for the Mac made available was 1.2b2a.

If you do please take the latest version from
http://alpha.uhasselt.be/Research/Algeb ... _versions/
I found a bug in the book handling code in the MP versions of Toga. This bug is
also present in the Windows versions but apparently went unnoticed.

I can probably do that. Although it would be nicer if someone like Tord who has the Intel compiler did it. I'll post up something later today anyway. You want 32 or 64 bits? and how many threads? And do you have a preference for some version?

Now that I've had time to work with it a bit, it seems that although these compile, they crash after a few moves when playing. I'll look into it a bit more...

I have heard from someone else who had the same problem. Sadly he couldn't supply any details and I don't have access to a Mac.
I am curious what "crashing" means. Whether the engine hangs or just sends incorrect information to the GUI?
Does the crash also happen if you execute the UCI commands directly in the terminal?
Does the crash also happen if the number of threads is 1?
Did you take the latest version from from
http://alpha.uhasselt.be/Research/Algeb ... _versions/? There was a bug in which is some cases Toga would report a1a1 as a move making polyglot unhappy for example. It happens only on a MP version using its own book.

the engine terminates. Tried with threads =1 and it does not crash. It appears to be happening while thinking about the second non-book move of the game. And yes I'm using the latest patch.
