Thanks Lucas.

However...

I have an Intel i5 4690K (Haswell). I have tried Demolito under 3 GUI's. It does not move or analyze under Arena, it displays 'waiting for engine' under Shredder 13 then does not move. Under Fritz 15 it is OK.

From the command line: initially it seems OK but when I issue 'go depth 15' it exits. If I issue 'ucinewgame' first then 'go depth 15' it displays its analysis but comes up with the move a1d2.

Can you try this compile?

Please test the following:

Bench from command line

Code: Select all

demolito.exe search 12 1

UCI simple test

Code: Select all

Now I have tried the new compile and the original one and they seem to behave identically from the command line, just as your attached outputs show.

Previously I did not issue the position startpos command.

Thanks. So it works by hand but not in the GUI?

Seems so. And upon checking again I found that even under F15 it can analyze but does not move. Can it be the order of commands the GUI sends to the engine?

It's a compiler issue. If I build under MSYS2 with MinGW and GCC 8.2.0 I get no compiler errors, just a couple of warnings, but no bench results at the end and the resulting exec crashes. Removing "-flto" and "-m" flags and lowering "-O" to 2 did not help.

Under Cygwin and GCC 7.3.0 everything is hunky-dory, but you need cygwin1.dll to run the execs. Here are two: one will run on any CPU with SSE3 (P4/Athlon 64 or later), the POPCNT one needs a Nehalem/Phenom or later. The required Cygwin1.dll is included

Thank you so much!

Indeed a compiler issue is the only explanation left. My guess would be a libc issue actually.

The first indicator that something is broken in the mingw-w64-gcc compiler (from Arch Linux AUR) is the size of the executable. My exe were built with -static, so should be self contained, and yet they are extremely small only 70kB or so). This problem didn't happen with the Ubuntu package.

The second indication is that nothing changed in the UCI code since last time, where mingw cross compiles worked flawlessly.

In fact, the mingw packages were removed from Arch official repos and moved to AUR, precisely because they were unmaintained and broken. That will teach me to rely on unmaintained and broken software

Thanks! This one works on my old quadcore w/o popcount, but there are some interesting glitches with it.

1. It runs with 837 kn/s in the 'search 12 1' test given by Lucas, which is around 20 faster than before
2. I had no problem to do a test game/match in cutechess-cli

3. It has weird problems in WB!
a) it does not run with Polyglot at all
b) with WB2UCI it triggers 'false stalemate claims' early in the game

After enabling the WB2UCI log to see what causes this (ofc an uci program cannot make false stalemate claims),
I see that it sometimes adds 'ponder 0000' to a move, which makes WB2UCI choke and it translates this to a false stalemate claim.

10180 >second: quit

I checked the debug of the cutechess-cli game and there are 13 'ponder 0000' entries there.
Right now I don't remember the specs and if WB2UCI is non-compliant or if there is sth to fix in Demolito?

I am still trying to figure out the incompatibility with Polyglot...

After enabling the WB2UCI log to see what causes this (ofc an uci program cannot make false stalemate claims),
I see that it sometimes adds 'ponder 0000' to a move, which makes WB2UCI choke and it translates this to a false stalemate claim.

Well, it should mean UCI2WB in all cases, time for correction was already over, sorry

The polyglot problem is some mysterious I/O conflict
With a standard poyglot file, which works in all other cases for more than a decade I get this??

With inbetween between Polyglot and Demolito it works though!? (some kind of I/O redirection problem?)

Yes, Demolito won't work with Polyglot as is:

"Ponder 0000" observed when running in console mode as well. Weird. Reminds me of the "bestmove 0000" issue with Wowl that remains unsolved as Wowl's author is unable to reproduce it on his end. Could these two issues be related?

edit: just saw your post, Günther. Agreed, this could have something to do with stdout and pipes; possibly a POSIX-vs-Win32 difference.
