I'm following this example to build a super simple "Hello World" Python module:
https://gist.github.com/ndevenish/ff771feb6817f7debfa728386110f567
I'm using CLion IDE on Windows. I get a number of linker errors and have been unable to track down the problem after spending hours on this. The g++ command that fails is:
g++.exe -O3 -DNDEBUG -shared -o hello_ext.dll hello_ext.cpp.obj -LC:/tools/mambaforge/pkgs/boost-1.80.0-py310h220cb41_1/Library/lib -LC:/tools/mambaforge/libs -lboost_python310 -lpython310 -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32
And the error output is:

(I have removed full paths from the above to make the command and output more readable.)
If I try to create a static library, it works, but of course then I cannot use it as a Python module.
I'm at my wits end as to what the issue is. Googling the specific linker errors did not provide useful answers. Can anyone help please?
