This is Nuitka-Python

This is a fork of CPython, that is called Nuitka-Python, and diverges in various ways from the original.

Our immediate goals are:

  • ☑ Windows: Add static linking (performance and lock down)
  • ☑ Windows: Reenable Windows 7 support (because why not)
  • ☑ LTO linking on Windows (performance and deployment size)
  • ☑ Automatic patches for packages built from pip
  • ☐ Support all major packages and provide upstream guidance.

Installation

Currently, you have to build Nuitka-Python from source code. It is questionable if deploying binaries makes sense, as you will have to compile from source code everything else that is installed afterwards, and the python.exe will be self-modifying with pip installs.

Use the following command in the root of a Nuitka-Python repository checkout:

build.bat -x64

This produces a portable Python installation in the output folder. It has a pip and setuptools, but not wheel out of the box. Nuitka-Python supports these all of these though, with differences to standard CPython that make it essentially always compile from source. Esp. the architecture of Nuitka-Python will be different, so binary wheels uploaded to PyPI cannot be installed, which will make it fallback to compiling from source.

The output folder can be moved freely, even to other machines. When you install via python.exe -m pip however, it will be self-modifying the python.exe to include the newly installed packages with static linking.
