I am trying to follow this tutorial to be abe to use C code in python. http://dfm.io/posts/python-c-extensions/
here is the gist https://gist.github.com/GreenJoey/b08528d6abe62da70f28f73c39c0efd0
when I try to compile it using python setup.py build_ext --inplace it fails with this error message:

looks like it cannot find unresolved external symbol PyInit__chi2 but the method is defined. see https://gist.github.com/GreenJoey/b08528d6abe62da70f28f73c39c0efd0#file-_chi2-c-L33
I understand that it is a linking error, but I only import "Python.h" once so I do not understand why it cannot find the method.
In my case this error was due to a mismatch between the module name I provided in setup.py and the module name used in the PYBIND11_MODULE() macro in my cpp bindings file (first argument to the macro).
I found the soultion here https://gist.github.com/douglas-larocca/099bf7460d853abb7c17
PyInit has to be marked with PyMODINIT_FUNC
PyMODINIT_FUNC PyInit__chi2(void)

ERROR: Failed building wheel for cx_freeze
Failed to build cx_freeze
ERROR: Could not build wheels for cx_freeze, which is required to install pyproject.toml-based projects
I tried Auto Fixing build tools, reinstalling pip, add sdk to path and I installed all the modules even if they are useless.
I don't have much experience with python but had to run some setup for rebuilding a tool we wrote in python and encountered the same issue.
This setup was also relying on cx_Freeze. I think there is a bug possibly in newer version of MSVC or cx_Freeze itself - no idea.
I worked around by installing this package individually directly from the source, running:
pip install --upgrade git+https://github.com/anthony-tuininga/cx_Freeze.git#main
I re-run the setup afterwards and it worked. The downside is that in the future I would need to manually upgrade this package rather than relying on it being restored auto-magically during rebuilding but at least it's fixed now for me.
Good luck, hope it works for you too.
Edit: This is a known issue, there is an open bug you can subscribe to follow progress updates:
https://github.com/marcelotduarte/cx_Freeze/issues/1662
To install the latest development build [1] compatible with Python 3.11:

I try to build the wheel package with Cython in my project.
My command:
python setup.py bdist_wheel
It could build success with Python3.6, but fail with Python3.7 and Python3.8.
They have the same os environment variables and they have installed the same package dependency.
By comparing two kinds of output, I found that they use different msvc compiler.
Python3.6 works with msvc2019, the full compile command of Cython:

Why they have different setting of building process?

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?
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.
I'm trying to build qpython (the kdb python interface) for python 3.6.3 (Anaconda) running on windows 7.
After downloading and unpacking qPython-qPython-1.2.2.zip
Executing "python setup.py build_ext --inplace"
gives...
running build_ext
building 'qpython.fastutils' extension

Which looks like setup is simply not setting the paths up correctly for the compiler.
A look in the qpython directory below shows fastutils.c sitting there waiting to be compiled.
This kind of thing seems to be a regular problem when trying to build python extensions on windows.
Any help / suggestions greatly appreciated.
