New chess engine: Texel

[fern]

I have played just a game and it seems to me that in similar positions which I know very well this programs of yours behave very very differently. It is really surprising.
I will try next time to save a game for you to see.

Texel x64 was compiled with VC++ 2012 beta, and I am not sure if an EXE created with this compiler will run under XP. I get a similar message when I create an EXE in VC++ 2010 and try run it under Windows 2000.

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.

[petero2]

Yes, C++11 contains some nice features, but as this thread shows, compiler support is still a substantial problem.

[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).

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...

JA builds available.

Windows/Linux/Android 64/32

Should work on all systems.

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.
