# Description:
#     Rules for running BEAM on C/C++/ASM files.
##
##  NOTE,   export BUILD_VERBOSE=1 to expose the BEAM invocation for debug.
##          (export -n BUILD_VERBOSE to turn it back off)
##
##  collect "real" BEAM errors into the *.beam files
##  push parser errors to the *.parser files
##  push stats (for debug) to *.stats files.

##  Run beam_configure for the C++ and C compilers.
##  This outputs the config files to ./obj/beam, you have to copy them
##  to the correct location.
##  This only needs to be done when something in the build environment changes.
##  See https://w3.eda.ibm.com/beam/beam_configure.html for documentation.
