Python build CFFI in API mode with Setuptools












0















I'm trying to learn about creating a CFFI modules, and packaging them with setuptools. When I run the build script build_foo.py I get an API mode library, but when I try to pip install . I get an ABI mode library.



Creates API mode



$> python build_foo.py
$> ls
build_foo.py _one_cffi.cpython-36m-x86_64-linux-gnu.so
_one_cffi.c _one_cffi.o


Creates ABI mode



$> pip install .
$> ls env/bin/site-packages
cffi pkg_resources
cffi-1.11.5.dist-info pkg_resources-0.0.0.dist-info
_cffi_backend.cpython-36m-x86_64-linux-gnu.so __pycache__
easy_install.py pycparser
Foo-0.1.dist-info pycparser-2.19.dist-info
foopkg setuptools
_one_cffi.abi3.so setuptools-40.6.2.dist-info
pip wheel
pip-18.1.dist-info wheel-0.32.3.dist-info

build_foo.py



#!/usr/bin/env python3

ffi = cffi.FFI()

int get_one() {
return 1;
}

"""
)

if __name__ == '__main__':
ffi.compile(verbose=True)


setup.py



from setuptools import setup
setup(
name = 'Foo',
version = '0.1',
packages = ['foopkg'],
cffi_modules=["foopkg/build_foo.py:ffi"],
install_requires = ['cffi']
)
