Cross compiling requires a Python interpreter for the build platform. The version of the build Python must match the version of the cross compiled host Python.\n\nconfigure for building on BUILD, usually guessed by config.guess.\n\ncross-compile to build programs to run on HOST (target platform)\n\npath to build python binary for cross compiling\n\nAn environment variable that points to a file with configure overrides.\n\nBounded code example (external data; do not execute automatically):\n```ini\n# config.site-aarch64\nac_cv_buggy_getaddrinfo=no\nac_cv_file__dev_ptmx=yes\nac_cv_file__dev_ptc=no\n```\n\nProgram to run CPython for the host platform for cross-compilation.\n\nCONFIG_SITE=config.site-aarch64 ../configure \\ --build=x86_64-pc-linux-gnu \\ --host=aarch64-unknown-linux-gnu \\ --with-build-python=../x86_64/python\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
