# $Id: Makefile 7123 2010-07-15 14:06:40Z svn_panicucci $ # gnu Makefile to build linux/Windows module for ipfw+dummynet. # # The defaults are set to build without modifications on PlanetLab # and possibly 2.6 versions. # On Windows, we use gnu-make and MSC # Some variables need to have specific names, because they are used # by the build infrastructure on Linux and OpenWrt. They are: # # ccflags-y additional $(CC) flags # M used by Kbuild, we must set it to `pwd` # obj-m list of .o modules to build # $(MOD)-y for each $MOD in obj-m, the list of objects # obj-y same as above, for openwrt # O_TARGET the link target, for openwrt # EXTRA_CFLAGS as the name says... in openwrt # EXTRA_CFLAGS is used in 2.6.22 module kernel compilation too # KERNELPATH the path to the kernel sources or headers # # Not sure about this (the name might be reserved) # ipfw-cflags our flags for building the module # # Other variables are only private and can be renamed. They include: # # VER linux version we are building for (2.4 2.6 or openwrt) #--- UNAME:=$(shell uname) $(warning including dummynet/Makefile) # lets default for 2.6 for planetlab builds VER ?= 2.6 #--- General values for all types of build --- # obj-m is the target module obj-m := ipfw_mod.o #-- the list of source files.
