# 2012-02-04 kimballr - modified for latest FSF directory and
#            sourceforge patch file name changes
# 2012-03-13 kimballr - added patches
#
# download, build and install GCC toolchain for MSP430
#
# prerequisites
# - bash
# - wget, GNU patch, GNU make
# - things needed to build binutils, GCC and GDB
#
# For Ubuntu/Debian that means:
# $ apt-get install build-essential; apt-get build-dep gcc
#
# environment
# - PREFIX - set to directory where toolchain is to be installed in
#            (defaults to /opt/mspgcc, I like $HOME/opt/mspgcc)
#
# make a build directory $HOME/mspgcc
# cd $HOME/mspgcc;
# mv dowloaded/thissript.sh into $HOME/mspgcc
# chmod +x ./build-mspgcc.sh
# PREFIX=$HOME/opt/mspgcc ./build-mspgcc.sh
# export PATH=$HOME/opt/mspgcc/bin:$PATH
# mspgcc-430 -mmcu=msp430g2553 sample.c

set -e # bail out if anything fails
#set -x # uncomment to show line by line execution very verbose
