# Makefile for miniupnpd (MiniUPnP daemon)
#
# This Makefile should work for *BSD and SunOS/Solaris.
# On Mac OS X, use "bsdmake" to build.
# This Makefile is NOT compatible with GNU Make.
# Linux users, please use Makefile.linux :
#  make -f Makefile.linux
#
# options can be passed to genconfig.sh through CONFIG_OPTIONS :
# $ CONFIG_OPTIONS="--ipv6 --igd2" make
