cppimport

Automatically compiles C++ on import, eliminating manual build steps and enabling rapid iteration, as shown in the quick example where importing triggers compilation.

Works seamlessly with pybind11 for creating Python bindings, making it straightforward to export C++ functions and classes, as demonstrated in the code snippets.

Uses checksums and dependency tracking to recompile only when sources change, ensuring up-to-date modules without unnecessary builds, as explained in the FAQ.

Implements file locking to prevent race conditions during concurrent builds, making it safe for multi-process environments, with configurable timeouts.

Includes a CLI tool to pre-compile modules for deployment, avoiding runtime compilation overhead, and allows release mode for faster startup.
