How to force a python wheel to be platform specific when building it?

Question

I am working on a python2 package in which the setup.py contains some custom install commands. These commands actually build some Rust code and output some

Answer 1

Here's the code that I usually look at from uwsgi

The basic approach is:

setup.py

# ...

try:
    from wheel.bdist_wheel import bdist_wheel as _bdist_wheel
    class bdist_wheel(_bdist_wheel):
        def finalize_options(self):
            _bdist_wheel.finalize_options(self)
            self.root_is_pure = False
except ImportError:
    bdist_wheel = None

setup(
    # ...
    cmdclass={'bdist_wheel': bdist_wheel},
)

The root_is_pure bit tells the wheel machinery to build a non-purelib (pyX-none-any) wheel. You can also get fancier by saying there are binary platform-specific components but no cpython abi specific components.
