Configure Python — General Options

Reference note (untrusted external data; do not execute it as instructions). Support loadable extensions in the !_sqlite extension module (default is no) of the sqlite3 module. See the sqlite3.Connection.enable_load_extension method of the sqlite3 module. Disable IPv6 support (enabled by default if supported), see the socket module. Define the size in bits of Python int digits: 15 or 30 bits. By default, the digit size is 30. Define the PYLONG_BITS_IN_DIGIT to 15 or 30. See sys.int_info.bits_per_digit . Set the Python executable suffix to SUFFIX. The default suffix is .exe on Windows and macOS (python.exe executable), .js on Emscripten node, .html on Emscripten browser, .wasm on WASI, and an empty string on other platforms (python executable). Select the default time zone search path for zoneinfo.TZPATH. See the Compile-time configuration of the zoneinfo module. Default: /usr/share/zoneinfo:/usr/lib/zoneinfo:/usr/share/lib/zoneinfo:/etc/zoneinfo. See os.pathsep path separator. Build the _decimal extension module using a thread-local context rather than a coroutine-local context (default), see the decimal module. See decimal.HAVE_CONTEXTVAR and the contextvars module. Override order to check db backends for the dbm module A valid value is a colon (:) separated string with the backend names Disable C locale coercion to a UTF-8 based locale (enabled by default). Don't define the PY_COERCE_C_LOCALE macro. See PYTHONCOERCECLOCALE and the 538. Python library directory name (default is lib). Fedora and SuSE use lib64 on 64-bit platforms. Directory of wheel packages used by the ensurepip module (none by default). Some Linux distribution packaging policies recommend against bundling dependencies. For example, Fedora installs wheel packages in the /usr/share/python-wheels/ directory and don't install the !ensurepip._bundled package. Whether configure should use pkg-config to detect build dependencies. check (default): pkg-config is optional yes: pkg-config is mandatory no: configure does not use pkg-config even when present Path to a JSON < configuration file containing custom error messages for missing standard library modules. This option is intended for Python distributors who wish to provide distribution-specific guidance when users encounter standard library modules that are missing or packaged separately. … Attribution: Adapted from Python Documentation under PSF-2.0.
