New chess engine: Texel

[petero2]

Correct VC++ 2012 beta does not support XP. See http://connect.microsoft.com/VisualStud ... ils/690617

There is supposedly a way around that, see http://tedwvc.wordpress.com/2012/03/11/ ... indows-xp/. It seems a bit complicated though.

Congrats and thanks Peter

I've tested texel under xubuntu 11-10 64bit with ScidVSpc. The texel32 seems to work fine but the texel62 returns an error (but it could be due to have a one bit old version).

Thanks for the info. I don't know what is wrong with the directory permissions. If it is the same user that created the directory and that tries to write to it I think rwx------ should be ok.

It is very strange.

Impressive work as always Peter!

You are a genius programmer. I hope one day I can be as competent as you are...

Thanks very much for the new engine release Peter.

Thanks a lot Jim.

It works perfectly on the systems I tested on (windows/linux/android), although I don't have Windows XP so I can not test that.

Your windows executables are about 15% faster than my windows executables, which means that the windows executables are now about as fast as the linux executables. Very nice.

Thanks again.

You're welcome.

It is possible to successfully compile the source with an older, unsupported version of GCC is you use the Boost libraries to handle the c++0x stuff.

Thanks, Jim. Though, I suppose one day I will have to upgrade from XP.

Ok, Peter- I fell for the joke. When everyone is thru laughing, you can tell me where in hell this engine came from really.
