# Top-level Makefile for Python
#
# As distributed, this file is called Makefile.pre.in; it is processed
# into the real Makefile by running the script ./configure, which
# replaces things like @spam@ with values appropriate for your system.
# This means that if you edit Makefile, your changes get lost the next
# time you run the configure script. Ideally, you can do:
#
# ./configure
# make
# make test
# make install
#
# If you have a previous version of Python installed that you don't
# want to overwrite, you can use "make altinstall" instead of "make
# install". Refer to the "Installing" section in the README file for
# additional details.
#
# See also the section "Build instructions" in the README file.

# frozen modules (including importlib)
#
# Freezing is a multi step process. It works differently for standard builds
# and cross builds. Standard builds use Programs/_freeze_module and
# _bootstrap_python for freezing and deepfreezing, so users can build Python
# without an existing Python installation. Cross builds cannot execute
# compiled binaries and therefore rely on an external build Python
# interpreter. The build interpreter must have same version and same bytecode
# as the host (target) binary.
#
# Standard build process:
# 1) compile minimal core objects for Py_Compile*() and PyMarshal_Write*().
# 2) build Programs/_freeze_module binary.
# 3) create frozen module headers for importlib and getpath.
# 4) build _bootstrap_python binary.
# 5) create remaining frozen module headers with
# ``./_bootstrap_python Programs/_freeze_module.py``. The pure Python
# script is used to test the cross compile code path.
# 6) deepfreeze modules with _bootstrap_python
#
# Cross compile process:
# 1) create all frozen module headers with external build Python and
# Programs/_freeze_module.py script.
# 2) deepfreeze modules with external build Python.
#
# FROZEN_FILES_* are auto-generated by Tools/scripts/freeze_modules.py.
