1 # From: @(#)bsd.prog.mk 5.26 (Berkeley) 6/25/91
4 # The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
10 # CLEANFILES Additional files to remove for the clean and cleandir targets.
12 # DISTRIBUTION Name of distribution. [bin]
14 # KMOD The name of the kernel module to build.
16 # KMODDIR Base path for kernel modules (see kld(4)). [/boot/kernel]
18 # KMODOWN KLD owner. [${BINOWN}]
20 # KMODGRP KLD group. [${BINGRP}]
22 # KMODMODE KLD mode. [${BINMODE}]
24 # LINKS The list of KLD links; should be full pathnames, the
25 # linked-to file coming first, followed by the linked
26 # file. The files are hard-linked. For example, to link
27 # /modules/master and /modules/meister, use:
29 # LINKS= /modules/master /modules/meister
31 # KMODLOAD Command to load a kernel module [/sbin/kldload]
33 # KMODUNLOAD Command to unload a kernel module [/sbin/kldunload]
35 # NOMAN KLD does not have a manual page if set.
37 # PROG The name of the kernel module to build.
38 # If not supplied, ${KMOD}.o is used.
40 # SRCS List of source files
42 # SUBDIR A list of subdirectories that should be built as well.
43 # Each of the targets will execute the same target in the
46 # SYMLINKS Same as LINKS, except it creates symlinks and the
47 # linked-to pathname may be relative.
49 # DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)
51 # MFILES Optionally a list of interfaces used by the module.
52 # This file contains a default list of interfaces.
57 # This is a variant of install, which will
58 # put the stuff into the right "distribution".
61 # install the program and its manual pages; if the Makefile
62 # does not itself define the target install, the targets
63 # beforeinstall and afterinstall may also be used to cause
64 # actions immediately before and after the install target
73 # bsd.obj.mk: clean, cleandir and obj
74 # bsd.dep.mk: cleandepend, depend and tags
75 # bsd.man.mk: maninstall
