[SOLVED] Edit location of compiled files with setuptools

Edit location of compiled files with setuptools

I am using setuptools to compile a pyx file using Cython using the following code in my setup.py

from Cython.Distutils import build_ext

extensions=[Extension("filtering.filter", "filtering/filter.pyx")

setup(
   name="..",
   ........
   ext_modules=extensions,
   cmdclass={"build_ext", build_ext}
   include_dirs=[".", numpy.get_include()]
)

I want to use pip install . to install this rather than python setup.py ... When running pip install . it compiles the file correctly, but stores it in the wrong place, it stores it in filtering/ rather than my_project/filtering/

I have tried using a setup.cfg with inplace=1 and also tried build_lib=. but this does not put it in the correct place either Any help appreciated

Solution

I'm writing a package in which all the code goes inside the src directory, and this approach works fine for me.

Package structure

src
 |-- foo
 |   |-- foo.pyx
 |
 |-- setup.py
 |-- setup.cfg
 |-- (.toml, LICENSE ... )

setup.cfg

[metadata]
.
.
.
[options]
packages = find:
package_dir = src
.
.
.
[options.packages.find]
where = src

setup.py

from setuptools import setup
from setuptools.extension import Extension
from Cython.Build import cythonize

ext_modules = [
    Extension(
        name = "foo.foo.pyx",
        sources = ["src/foo/foo.pyx"]
    )
]

if __name__ == "__main__":

    setup(
        ext_modules=cythonize(ext_modules)
    )

I'm not sure if the last part of the .cfg file (where ...) is strictly necessary.
