I'm curious if you purposely left out the numpy part in the solution? include_dirs=[numpy.get_include()]

@lasofivec, thanks for your feedback!

No, that was not intentional - I change the post.

In that case, from my experience the wrapping solution won't work. Or at least I didn't find a way of wrapping the numpy.get_include() in a clever way. Seems to me like using a newer version of setuptools is the only working solution (or explicit installing it, like in your last code snippet)

not a super clever way, but a way :

class WhateverExt(Extension): def init(self, *args, *kwargs): self._include = [] super().init(args, **kwargs)

@property
def include_dirs(self):
    # defer import of numpy
    import numpy
    return self._include + [numpy.get_include()]

@include_dirs.setter
def include_dirs(self, dirs):
    self._include = dirs

ext_modules = [ WhateverExt( name="stuff.stuff", sources=["src/stuff/stuff.pyx"], )]

@jacboi What version of setuptools did you use ?
