##
## Autotools build wrapper.
## Kieran Bingham
## August 2014
##
## Configures and builds under build-<arch>
##
## Cross compilation can be supported by defining
## ARCH=<target arch>
## CROSS=<cross prefix of toolchain on path>
##
##
## Some very useful advice used here from http://mad-scientist.net/make/multi-arch.html
##
# Disable all implicit build targets
.SUFFIXES:
#ARCH?=armv7
ARCH?=$(shell uname -m)
BUILD_DIR=build-$(ARCH)
SOURCE_DIR=$(CURDIR)
export CC=${CROSS}gcc
export LD=${CROSS}gcc
export CXX=${CROSS}c++
export ARCH
export PATH
export DESTDIR
# No make directory output from this wrapper
MAKE:=$(MAKE) --no-print-directory
.PHONY: all
all: $(BUILD_DIR)/Makefile
