#
# This script builds and installs binutils, gcc and newlib in the order
# necessary for the whole thing to work.  The present version is based
# on OsmocomBB's gnu-arm-build.2.sh script, which is in turn based on
# yet another source.  The present version has been concocted by
# Spacefalcon the Outlaw for use in the FreeCalypso project.
#
# This script needs to be invoked with two arguments:
#
# $1: the path to the directory containing the upstream binutils, gcc
#     and newlib source tarballs;
#
# $2: the path to the directory where the built toolchain should be
#     installed.
#
# Note that there isn't a single install step at the end, instead this
# script will build and install one component, then proceed to build the
# next component which depends on the previous one, etc.  For this reason
# you should create a dedicated install directory that is writable by your
# regular (non-root) uid, then run this script to populate that directory
# with the toolchain.

if [ $# != 2 ]

	echo "usage: $0 path-to-tarballs path-to-install"
