Hi Richard (Or anyone else who knows the procedure)
Once I download Critter how do I get it up and running? I have Rybka 4, Shredder, and Chessmaster 10 on my computer.
Thanks Allan

Eclipse CDT is very powerful. The Eclipse interface can be intimidating at first, but is in no way inferior to MS VisualStudio once you get used to it. Plus, it's cross-platform and cross-language.

QtCreator is the way if you only care about C++ and don't want to learn Eclipse.

Regarding the multithreading crashes on Linux: I suppose you are aware that POSIX condition variables have very different semantics from WinAPI event objects. They can also wakeup spuriously, so you need to guard against that.

Hi Richard. Would it be possible to recompile the gtb32.dll and gtb64.dll files to use the latest Gaviota tablebase probing code (version 0.4)? There's a bug in previous versions of the code to do with en passant captures, that causes problems in positions like this:

[D]8/7p/6p1/6P1/5K1k/8/8/8 b - -

When using tablebases, Critter wants to play 1... h5?

Yes, that was the point of separating TB access code into dlls. After updating them to v0.4, the fix will work for both Critter 0.90 and Critter 1.00 without touching the executables.

Updated package will be available in 2-3 days.

Excellent, thank you Richard.

Thanks,

It is amazing how much better free software support is than paid software sunpport!
