# Not using "set -e" due to watchdog clean code below (FIXME)

# This script is invoked by the CI system to build a nerves_system_br configuration.

# The following environment variables should be set:
#  CI_DEFCONFIG_DIR - the name of the directory under configs
#  CI_DEFCONFIG     - the part of the filename that comes before _defconfig
#
# For example, to build configs/nerves_system_bbb/elixir_defconfig, the above variables
# are:
#  CI_DEFCONFIG_DIR=nerves_system_bbb
#  CI_DEFCONFIG=elixir
#

# Buildroot doesn't like LD_LIBRARY_PATH set
export LD_LIBRARY_PATH=
