Build Cython Extensions

概要

This skill offers a comprehensive framework for managing the complexities of Cython extension modules, particularly when dealing with legacy codebases or breaking changes in core libraries. It provides structured phases for pre-build analysis, systematic type replacement (especially for NumPy 2.0 deprecations), and robust installation procedures. Whether you are troubleshooting compilation failures, migrating to Python 3.x, or ensuring clean builds in global environments, this resource ensures high-performance C-extensions are correctly compiled and verified through proactive identification of common pitfalls and rigorous testing patterns.
