I would love to use Hawkeye as an opponent for my Stockfish-Testwork, because Stockfish needs more strong opponents. But therefore I need a x64 popcount Windows-compile...but I couldnt find one.

Feel free - somebody surely has one. If I get one , I will add it to the Github and let you know. Nothing but Mac here.

How's version 1.02 performing?

[Dann Corbit]

I made a version here:
https://www.dropbox.com/s/aq2g71f4s6dfg ... er.7z?dl=0
Not sure how good it is (I ended up using the makefile called 'Makefile' in src folder after a little fiddling).

I had to make a few obvious changes, but one that I am not absolutely sure of is here (no killpg call for windows):

Code: Select all

#ifdef WINDOWS
        for &#40;i = 1; i < PrN; i++) &#123;
            TerminateProcess&#40;ChildPr&#91;i&#93;, 0&#41;;
            CloseHandle&#40;ChildPr&#91;i&#93;);
        &#125;
#endif
        exit&#40;0&#41;;
        int pid;
#ifndef WINDOWS
        killpg&#40;getpgid&#40;pid&#41;, SIGTERM&#41;; // Falling on your own blade should be taken care of by exit&#40;0&#41; in Windows
#endif
    &#125; else if (!memcmp&#40;mstring, "epd", 3&#41;) &#123;
        ptr = mstring + 4;
        value = atoi&#40;ptr&#41;;
        epd_test&#40;"op.epd", value&#41;;
    &#125;
&#125;

We already killed the child processes just above, so the exit(0) should get rid of the calling process. I assume the current executable is the caller.

[MikeB]

Thanks Dann - what you are looking is a hack to ensure the process is killed when it needs to get killed when running in a tournament mode ( large number of automated games either under xBoard or Bob's command line tool)

The engine without that hack may keep running after the game is over . I have seen this numberous times under xBoard or under Bob's command line tool. It is only those engines that share a common genealogy and it is only a problem in the Mac. The hack ensures the engine is killed when it is supposed to.

There is nothing worse than completing a tournament and seeing 20 instances of an engine running in the background when the tournament is over.

[Graham Banks]

I've had an email request to ask whether or not you can provide a compile for older computers.

I've had an email request to ask whether or not you can provide a compile for older computers.

Hopefully somebody can if they see this.

[Jamal Bubker]

Thank you Michael B for releasing this new improvement of Gull.

Great job !

[Jamal Bubker]

Thanks Dann for compiling a windows version of Hawkeye

Your windows compilation work and also Daniel Jose and Jose M Velasco are a precious gift to Windows Environment's Users like me !
