The example does not explain how to handle .h file.

This example does not explain how to deal with the .h file. When I package it according to the example, I find that the wheel file is normal, but the .h file is not packaged in the source code of tar.gz. The code is below.

extension_modules = [
    Pybind11Extension(
        'classicML/backend/cc/ops',
        sorted(glob('classicML/backend/cc/*.cc')),
        include_dirs=[
            '/usr/local/include/eigen3',  # /path/to/eigen3/download
        ],
        language='c++',
    )
]

When I realized this problem, I modified the source code to the following.

sorted(glob('classicML/backend/cc/*[cc.h]'))

Runpython3 setup.py sdist bdist_wheel. The .h file can be packaged into the source code, and there is a problem with generating the wheel file.😭

I just started learning to use pybind. I don’t know if this is a problem with setuptools or pybind.

Add the file to your MANIFEST.in. That controls the SDist. Don't add it to your sources, that controls the compile. I think there's a headers slot in Extension, but that's optional and has no effect on the SDist. Or the include paths IIRC.

Use pip wheel . to build wheels, or better yet use pip install build followed by python -m build to build both sdist and wheel.

I solved the problem using the method you provided. Thanks.
