With MacOS, try with the laster makeFile i pushed:
make clean
make -j profile-build ARCH=apple-silicon COMP=clang LTO=yes
Same prob on Mac :-(

All other engines e.g. Brainlearn, Stockfish, coechess and so on can be compiled here on Mac without any problems / errors or warnings.
In the file engine.cpp edit the function search_clear() to this:

Code: Select all

void Engine::search_clear() {
    wait_for_search_finished();

    MCTS.clear();  //mcts
    tt.clear(threads);
    threads.clear();

    // @TODO wont work with multiple instances
    Tablebases::init(options["SyzygyPath"]);  // Free mapped files
}
Try compiling again.

I built with the 14.2.0, but with the fixed makeFile and an update to the latest 15.1.0 gcc version (the latest stable version also on linux), it works perfectly on windows and also on linux:
msys2 and mingw.
No need to eliminate the part
//for wdl use begin
if (!WDLModel::is_initialized())
{
WDLModel::init();
}
//for wdl use end

To me it looks sufficient to compute the WDL array once at startup.
No need to recompute it every time a new game is started.
YMMV of course.

Edit: It also works around a warning I got with gcc/g++ 12.2.0

Anyway, the proposed modif is correct: the WDLModel is also initialized in the main method. So, it's unnecessary in search_clear.
Done.

Thank you.

btw. compiling on windows is buggy too.

But this is normal with every new release from you.
MacOS version:

Thanks for the new version!
With this one I'm for the first time able to show statistically relevant positive difference in using MCTS- mode, at least for a certain suite of positions with a certain setting and hardware- TC. With the suite of 256 positions, I already pasted now and then, at Talkchess latest here

viewtopic.php?p=980708#p980708

, which is on github now too

https://github.com/amchess/ShashChess/wiki/Battery-2025

, I had 2 more runs with 6 threads (5 concurrencies) of the 16x3,5GHz- CPU, MultiPV=4, 30"/pos., compared MCTS true with 1 thread out of the 6 to MCTS false:

These two runs differ in 11/256 solutions (end of table), considering the time -indices too,
that makes a difference of 14 ElotStatTS (Frank Schubert)- Elo at an error bar of 3, regards
