Link error when building tests and examples under Windows with msys2 tool chain

[jalvesz]

Description

I'm trying to build and test stdlib on a Windows machine with msys2 tool chain, using gnu compilers (gcc/gfortran) 14.2.0-3 version.

I have a small python script to customize the cmake build as:

# build with cmake
subprocess.run("cmake -B build -G Ninja -DBUILD_TESTING=on"+
                   " -DCMAKE_MAXIMUM_RANK:String=4 "+
                   " -DCMAKE_BUILD_TYPE=Release"+
                   " -DCMAKE_Fortran_COMPILER=gfortran", 
                   shell=True, check=True) 
subprocess.run("cmake --build build -j 16",shell=True, check=True)
subprocess.run("ctest --test-dir build/test",shell=True, check=True)

I another machine where I use the tool chain from equation.com everything works, but here I get the following error when linking the hash_functions tests:

[376/695] Linking CXX executable test\hash_functions\test_hash_functions.exe

Expected Behaviour

should link, build and run

Version of stdlib

master

Platform and Architecture

Windows (mingw-64)

Additional Information

No response

If I comment out the following tests from the CMake

#add_subdirectory(hash_functions)
#add_subdirectory(hash_functions_perf)

I managed to launch all other tests.

My bad, I had to specify the three compilers as:

-DCMAKE_Fortran_COMPILER=gfortran -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++

Closing this issue as there is no issue.
