Makefile.framework

# --------------------------------------------------------------------------------------------------
# Makefile used to build the Legato application framework.
#
# This Makefile is intended to run as part of a larger build system.  The following variables
# must be set by that system:
#
# - TARGET = e.g., localhost, ar7, wp85, raspi, etc.
# - CC = path to the appropriate C compiler for the target.
# - STRIP = path to the appropriate debug symbol stripper for the target.
# - READELF = path to the appropriate ELF file info extractor for the target.
# - OBJCOPY = path to the appropriate object file copier/translator utility for the target.
#
# Other variables that can be set:
#
# - LEGATO_ROOT = directory under which the Legato AF sources can be found. Defaults to $(CURDIR).
# - BUILD_DIR = directory under which the build artifacts and outputs should be placed.
#               Defaults to $(LEGATO_ROOT)/build/$(TARGET).
# - LEGATO_SYSROOT = directory in which the build tool chain's system files can be found.
