3 years ago Doing cd ./interfaces/python/ && python setup.py build_ext --inplace works on my Mac (OSX 11.0.1, Anaconda 4.10.1, Python 3.8.2).
My suspicion is that your GCC does not find the correct header files. Maybe you have multiple GCC installations (some homebrew packages ship one, Anaconda Cython might have one, ...).
Please try the following (see stackoverflow and Cython Tutorial):
helloWorld.pyx:
print("Hello world")setup.py:
from distutils.core import setup
from Cython.Build import cythonize
setup(
ext_modules = cythonize("helloWorld.pyx")
)Run on command line:
python setup.py build_ext --inplaceDoes this compile?

On Python 3.7, Mac OSX 10.14, I run into the following problem when trying to install the Python interface, in each way outline in the README.rst file:
Any insight into the problem would be greatly appreciated.
Thanks!
