How can I build a C++ program in python?

Question

I am using Anaconda. I want to build a source code from github: https://github.com/mmolero/pypoisson

When I use the following command in the terminal, it gives the following error: Command: python setup.py build

Error:

Not only for this source code but also for other code fails to build. It should be noted that I installed visual 2015, visual 2017, GCC compiler in my PC. The operating system is Windows 10.

Different source code needs different types of compiler, How can I solve this issue?

Answer 1

The critical section of that output is fatal error C1189: #error: OpenMP is required. At a guess, I'd say that this means that you need to have OpenMP available, and you don't. There's another SO thread on installing OpenMP on Windows, which includes some pretty recent answers.
