# Compile ref C++ files, to check them for validity
#
# By default, each file is compiled with three different sets of values of F
# Prime guards: 
# - Default values as found in fprime/config/FpConfig.h
# - All guards turned on
# - All guards turned off (except FW_PORT_SERIALIZATION for components
#   containing serial ports)
#
# If this script is run with the --all flag, each file is compiled with all
# possible combinations of values of F Prime guards with these exceptions:
# - FW_AMPCS_COMPATIBLE and FW_CMD_CHECK_RESIDUAL remain set to the default
#   values found in fprime/config/FpConfig.h
# - FW_SERIALIZABLE_TO_STRING and FW_ARRAY_TO_STRING always have the same value
# - FW_PORT_SERIALIZATION is always on for components containing serial ports
