# Toolchain buildscript
# This script requires TWO command-line parameters: the number of threads for make and the
# directory under which all tools are going to be installed.

# Before running the script, the following packages need to be installed in your distro:
# (These are Ubuntu package names, if you don't use Ubuntu, look for equivalents)
#
# build-essential, automake, autoconf, m4, flex, bison, texinfo

THREADS="-j $1" # DON'T CHANGE
BUILD_HOME=$2   # DON'T CHANGE


# if you want less messages from compilation in your output, use SILENT_BUILD=1
SILENT_BUILD=

# use the GCC target name for the desired architecture here, i.e, "avr", "mips-elf", etc.
TARGET=

# You should probably use the most recent stable versions... but sometimes you need
# a bit more research...
