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

_one_cffi.abi3.so setuptools-40.6.2.dist-info
pip wheel

ffi = cffi.FFI()

ffi.set_source("_one_cffi",

)
if __name__ == '__main__':
