Crate pyo3_build_config

Configuration used by PyO3 for conditional support of varying Python versions.

This crate exposes functionality to be called from build scripts to simplify building crates which depend on PyO3.

It used internally by the PyO3 crate’s build script to apply the same configuration.

Structs

BuildFlags

A list of python interpreter compile-time preprocessor defines.

CrossCompileConfig

Configuration needed by PyO3 to cross-compile for a target platform.

InterpreterConfig

Configuration needed by PyO3 to build for the correct Python implementation.

PythonVersion

Triple

An LLVM target “triple”. Historically such things had three fields, though they’ve added additional fields over time.

Enums

BuildFlag

PythonImplementation

Functions

add_extension_module_link_args

Adds linker arguments suitable for PyO3’s extension-module feature.

cross_compiling_from_to

Detect whether we are cross compiling and return an assembled CrossCompileConfig if so.

find_all_sysconfigdata

Finds _sysconfigdata*.py files for detected Python interpreters.

parse_sysconfigdata

Parse sysconfigdata file
