I updated xcode-select install to the latest version, which doesn't support libstdc++ anymore, therefore libraries such as 'iostream' can't be found when I run:
$ python3 setup.py build_ext --inline
Error message

I found this explanation: ld: library not found for -lstdc++.6
and this vague solution: https://forums.developer.apple.com/thread/106114
Is there a way I can append pass '-std=libc++' to the clang command?.
Setup.py file lookes like this:
from distutils.core import setup, Extension
import numpy
import os
# os.environ['CC'] = 'g++';
setup(name='pafprocess_ext', version='1.0',
ext_modules=[
Extension('_pafprocess', ['pafprocess.cpp', 'pafprocess.i'],
swig_opts=['-c++'],
depends=["pafprocess.h"],
include_dirs=[numpy.get_include(), '.'])
],
py_modules=[
"pafprocess"
]
)
