New chess engine - DoubleCheck 1.0 (Lucas Braesch)

[lucasart]

Compiled without issues and seems to work well on my Mac using Sigma Chess as GUI.

That's good news

Just ran a statistically meaningless two game match against Critter-1.2.1. Both engines had one thread, 16 MB hash and no book. Not surprisingly, Critter won 2-0.

I don't think Critter and DoubleCheck belong in the same playground. Critter is probably 1000 elo stronger than DoubleCheck

Doesn't work for me under XP 64-bits (a message about not compatibility with the SO is showed). I'm using Arena 2.0.1 ...

Could you show the error messages given by your compiler ? I'll have a look!
Unfortunately I don't have windows, so I can't really test it. I just try to write code that is as portable as possible, but w/o testing I can't be sure it *is* portable
Thank you

Yes. Thanks for the new engine.

Well, it should still beat me handily.

I get a similar message when running under Windows 7 x64 Home Edition. If I run the exe directly, the message says:

"The version of this file is not compatible with the version of Windows you're running. Check your computer system's information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software developer."

If I run it in Arena, the message is
"Unsupported 16-bit Application

The program or feature "\??\C:\Temp\DoubleCheck\DoubleCheck.exe" cannot start or run due to an incompatibility with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available."

When I look at it in my hex editor, it looks like an ELF format executable, with the characters ELF instead of MZ at the start of the file.

Did you compile it with a 64 compiler under Windows ?
The executable that I give is a Linux64 executable, so of course, it doesn't work under Windows (nothing to do with Arena)

I was looking at your compile, assuming it was a Windows one because the file name ended in .exe. Silly me.

Did I really put an .exe ? Anyway, I'll try to see how to generate a win64 executable. I know it is possible to do that with gcc under Linux
