# Makefile for libhubbub
#
# Toolchain is exported by top-level makefile
#
# Top-level makefile also exports the following variables:
#
# COMPONENT  Name of component
# EXPORT     Absolute path of export directory
# TOP        Absolute path of source tree root
#
# The top-level makefile requires the following targets to exist:
#
# clean      Clean source tree
# debug      Create a debug binary
# distclean  Fully clean source tree, back to pristine condition
# export     Export distributable components to ${EXPORT}
# release    Create a release binary
# setup      Perform any setup required prior to compilation
# test       Execute any test cases

# Manipulate include paths
CFLAGS += -I$(CURDIR)

# Release output
RELEASE = ${TOP}/${COMPONENT}.a

# Debug output
DEBUG = ${TOP}/${COMPONENT}-debug.a

# Objects
OBJS = hubbub parser
