# Makefile for nulib2 stuff (should work with non-GNU make).
#
# You can use:
# 	make (builds nulib2 and checks for libnufx.a)
# 	make shared (builds nulib2 and checks for libnufx.so)
#
# This will try to link against the library in $(NUFXSRCDIR) first, then
# look for a copy in the standard system install location (usually
# /usr/local/lib).
#
# Note that this really wants to find $(NUFXLIB) for dependency checking.
# If you're building against a copy in /usr/local/lib, just put a '#' in
# front of the "NUFXLIB" line below.
#

# set this to where the NuFX library and ".h" file live
