Makefile.am

# Makefile.am is used with REX compiler such that libaccparser.la is built and linked into librose lib.
# accparser is a submodule of REX under folder src/frontend/SageIII and the source files of accparser are built into libaccparser.la, which then be added to libsage3.la which is added to librose.so.

# This file is not needed to build the standalone accparser.

# There is a bug in Antlr 4 on Linux. It can't recognize -o arguments that specify the output folder. The generated files are always at the same location as .g4 inputs.
# Thus, we copy the g4 files to the build folder first and then generate outputs there.
