GCC 15.2.0 appears to have several stability issues, especially in the Mingw environment on Windows. Here is a summary of the situation:

Known Issues with GCC 15.2.0 on Windows
LTO (Link Time Optimization) Problems:

Optimization during linking is unstable.

Generates unpredictable "undefined reference" errors.

Particularly problematic for complex projects such as chess engines.

Linker Regressions:

Less tolerant handling of symbols.

Issues with inter-translation unit optimizations.

Windows API Compatibility:

Problems with some system libraries.

Difficulties with full static linking.

MinGW-w64 Specific Issues:

The Windows implementation is always a step behind the Linux version.

Greater challenges in maintaining compatibility.

Recommendations
Continue to Use GCC 14.2.0:

Compiling on Mac does not work.

ld: symbol(s) not found for architecture arm64
clang++: error: linker command failed with exit code 1 (use -v to see invocation)

In that case, make sure to include the complete error log.

Thank you.

I will not create a github account to help you with your buggy engines.

Thank you.

btw. compiling on windows is buggy too.

But this is normal with every new release from you.

I fixed the makeFile to also work with mingw 15.1.0, the latest stable one.
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.

See if the src folder contains (besides the WDL* folder) some WDL*.c and WDL*.h. Delete those files (or move them somewhere else) and try to build again. It should go well. I solved this problem on Linux, but the issue was the same.

Thx for your help ... but on Mac it does not work. Itried your setup.

With his older Shash dev versions he send me about 35 different versions to fix his own code to run on Mac.

He is a try and error coder.
