#!/bin/sh

# This is my script for building a complete MinGW cross-compiler toolchain
# that runs under Linux to produce executables that run under Windows.  It
# probably works (or can easily be adapted to work) under any unix system.
#
# It is based in large part on Sam Lantinga's script, which in turn was
# based partly on Ray Kelm's script, which in turn was built on
# Mo Dejong's script for doing the same, but with some added fixes.
#
# My changes:
#       1. Adapted the script to the new packaging of MinGW GCC, which is
#          currently split into core and auxiliary components.
#       2. The script now determines the GCC and BINUTILS directory name
#          directly from the tar file contents.  This gets around common
#          problems due to the directory names not always following the
#          expected patterns.
#       3. Grouped together and simplified the macros that users need to
#          define.
#       4. Made optional components truly optional -- leave the
#          corresponding archive names blank and they will be ignored.
#       5. Included an option to purge the installation directory before
#          installing the current cross-compiler.
#
# NOTE: If you choose a destination directory for the installation (set
# in the macro PREFIX) for which you do not have write access, you will
# need to run this script with root (or equivalent) privileges.
