2 # gnu Makefile to build linux/Windows module for ipfw+dummynet.
4 # The defaults are set to build without modifications on PlanetLab
5 # and possibly 2.6 versions.
6 # On Windows, we use gnu-make and MSC
8 # Some variables need to have specific names, because they are used
9 # by the build infrastructure on Linux and OpenWrt. They are:
11 # ccflags-y additional $(CC) flags
12 # M used by Kbuild, we must set it to `pwd`
13 # obj-m list of .o modules to build
14 # $(MOD)-y for each $MOD in obj-m, the list of objects
15 # obj-y same as above, for openwrt
16 # O_TARGET the link target, for openwrt
17 # EXTRA_CFLAGS as the name says... in openwrt
18 # EXTRA_CFLAGS is used in 2.6.22 module kernel compilation too
19 # KERNELPATH the path to the kernel sources or headers
21 # Not sure about this (the name might be reserved)
22 # ipfw-cflags our flags for building the module
24 # Other variables are only private and can be renamed. They include:
26 # VER linux version we are building for (2.4 2.6 or openwrt)
30 $(warning including dummynet/Makefile)
32 # lets default for 2.6 for planetlab builds
35 #--- General values for all types of build ---
36 # obj-m is the target module
39 #-- the list of source files. IPFW_SRCS is our own name.
