I tried building a project with scikit-build 0.17.1 using python -m build which builds in a virtual environment in mingw on windows. It fails while configuring cmake. Here is the relevant output.

-- Configuring incomplete, errors occurred!

The error Could NOT find Python3 (missing: Python3_LIBRARIES Development.Module) is caused by -DPython3_LIBRARY:PATH=libpython3.10.a which is not a full path.

I did some debugging and it looks like the problem is related to this old TODO:

scikit-build/skbuild/cmaker.py

Line 605 in 84c7e4c

# TODO(opadron): what happens if we don't find a libpython?

Most code paths in CMaker.get_python_library() check that the library path actually exists. But since the library is not found in a virtual environment, we end up with the default value from _guess_python_library() falling through.

To reproduce, run the following in a virtualenv.

from skbuild.cmaker import CMaker

print(CMaker.get_python_library("3.10"))

There is some relevant discussion about why virtualenvs don't have a copy of the library at python/cpython#87500

So, it seems like in a virtualenv, get_python_library() should always return None.

@dlech
fix: Don't set Python_LIBRARY when using venv
32dcf8d 
If scikit-build is running in a virtual environment, then the path to
libpython is not available. The virtual environment does not copy this
file and it overrides sysconfig variables so we can no longer find the
original location of the library.

Fixes: scikit-build#940

I found #119 which indicates that using distutils.sysconfig was added to work around the issue of the library not being present in virtualenvs. Since distutils is slated to be removed in Python 3.12, I think we will need to come up with a different solution here.

As a source for some ideas, here is a dump of pprint(sysconfig.get_config_vars()) from my mingw virtualenv. We can see that most paths have been replaced with C:/Users/extra/source/repos/scikit-build/.venv/... but there are a few variables like installed_base and prefix that are set to C:/msys64/clangarm64 that could perhaps be used to find the location of the library file.

fix: validate value before returning library path
586852b 
In CMaker._guess_python_library(), there is a path where python_library
can be set to a file name without a path. For example, this happens
when using a venv in a MinGW envronment on Windows. This gets passed
to CMake via Python_LIBRARY which causes CMake to fail.

To fix it, we validate that the path exists on disk before returning
the value or return None if it does not exist.

Fixes: scikit-build#940

I finally found a change that fixes finding the libaray: dlech@e04ae41

But then CMake finds the wrong compiler (MSVC instead of clang or gcc from MSYS) and the build fails anyway. So maybe trying to build in an isolated environment with build in an MSYS2 shell is just not a good idea.

Does it work with scikit-build-core? Also, could you remind me what sys.platform returns, and if it's win32, how you can detect mingw?

sys.platform is 'win32'.

sysconfig.get_platform() is 'mingw_aarch64'.

Testing for the existence of the MSYSTEM environment variable can be used to detect running in MSYS2.

@dlech since 3245109 is causing regressions for opencv-python build, and it seems the actual fix is #944, perhaps the former was not actually needed?

No, it is not critical and could be reverted to fix opencv if we don't want to spend time trying to dig into it more.

Would it make sense to return "" instead of None? I think this would fix the "regression" (though, longer term, opencv should check to see if a python library was found before working with the string). On non-Windows systems, there's no point to having the Python library; it's only needed on Windows and linking to it is actually a bad idea. It's also not available on the manylinux images to stop users from linking to it and save space.

FYI, this function is typed str | None, even before this change, so mypy should not have allowed this error to happen.
