Error in compiling cython extension on Python 3.6.4 on Windows 8 using MS Visual Stud - goldenmean - Jun 3, 2019
I have a setup.py file as below:
Code
#from distutils.core import setup
from setuptools import setup, find_packages, Extension, Command
from Cython.Build import cythonize
setup(
ext_modules = cythonize("cyt_hello_world.pyx")
)And a simple print as below in file cyt_hello_world.pyx
Code
print("Cython Hello World!")I compile this cython extension on Windows using below command
python setup.py build_ext --inplace
Whether I use distutils or setuptools in the setup.py file above, both give errors as below.
Error seen, If I use distutils
F:\PythonCode>python setup.py build_ext --inplace running build_ext building 'cyt_hello_world' extension
error: Unable to find vcvarsall.bat
If I use setuptools, below is the error
F:\PythonCode>python setup.py build_ext --inplace running build_ext building 'cyt_hello_world' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools":
I have Microsoft Visual Studio installed at path : C:\Program Files (x86)\Microsoft Visual Studio 12.0
I can see file vcvarsall.bat in MSVisual Studio 12.0 installation folder C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC
How can i point to this *.bat and resolve these errors if i use distutils OR
How can i fix the errors: "Microsoft Visual C++ 14.0 is required", if any different installation needed?
Can someone give any inputs?
NOTE: I have tried setting set VS90COMNTOOLS=%VS120COMNTOOLS% but no success, same error of vcvarsall.bat . I have also added C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC to my windows PATH variable, but no success.
