Mac build script for Sourcery CodeBench Lite Edition - http://gnuarmeclipse.livius.net/wiki/Toolchain_installation_on_OS_X

arm-cs-tools-build.sh

#!/bin/bash

# This script generates the Code Sourcery ARM EABI Toolchain on MAC OS X 10.7
#
# The main trick here is the possibility to build previous versions, required
# when maintaining older projects that no longer build with newer version.
#
# The new toolchain is installed at
# "$HOME/Developer/Cross/arm-cs-tools-$MENTOR_RELEASE-$TODAY"
#
# The implementation uses James Sneyder's Mafefile, available from
# https://github.com/jsnyder/arm-eabi-toolchain
#
# The build process also requires some special packages, that will be
# installed in a non-system folder, to avoid poluting the system
#
# There are many releases for Code Sourcery, and many releases of jsnyder's
# Makefile, so we need to identify them propely.
#
# The MENTOR_RELEASE is the internal value used by Mentor, and 
# can be obtained from the Mentor URLs
# https://sourcery.mentor.com/sgpp/lite/arm/portal/release2188
#
# Change log:
# 20140422 - since the build requires a strictly controlled environment, it is preferred to redefine the PATH; especially avoid the MacPorts /opt/local folder
# 20121030 - add 2012.03-56 e3f4013, functional on OS X 10.7.5, Xcode 4.5.1
#            switch from zip archive to git 
#
