# PERSONALIZATON :

# You probably want to change this:

export HOST_CC="gcc" # default: gcc
export CPU_COUNT="4"
export LANGS="c,c++" # default: c,c++ but fortran should also work

# ----------------------------------------

# GLOBAL EXPORTS :

export HOST_KERNEL=`uname -s | tr '[:upper:]' '[:lower:]'` # should be lowercase, default: linux
export HOST_PLATFORM=`uname -i`
export HOST_MACHINE=`uname -m`
export OUTPUT_FOLDER="/opt/qnx800" # default: /opt/qnx800
export TARGET_FOLDER="$OUTPUT_FOLDER/target" # default: /opt/qnx800/target
export HOST_FOLDER="$OUTPUT_FOLDER/host" # default: /opt/qnx800/host
export TARGET_ABI="arm-unknown-nto-qnx8.0.0eabi" # default: arm-unknown-nto-qnx8.0.0eabi
export HOST_OS="$HOST_MACHINE-$HOST_PLATFORM-$HOST_KERNEL-gnu" # default: i686-pc-linux-gnu
export PREFIX="$HOST_FOLDER/$HOST_KERNEL/$HOST_MACHINE/usr"
export BUGURL="https://github.com/extrowerk/bb10-toolchain/"

# ----------------------------------------

# ENVIRONMENT :
