1# From: @(#)bsd.prog.mk 5.26 (Berkeley) 6/25/91 2# $FreeBSD$ 3# 4# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device 5# drivers (KLD's). 6# 7# 8# +++ variables +++ 9# 10# CLEANFILES Additional files to remove for the clean and cleandir targets. 11# 12# DISTRIBUTION Name of distribution. [bin] 13# 14# KMOD The name of the kernel module to build. 15# 16# KMODDIR Base path for kernel modules (see kld(4)). [/boot/kernel] 17# 18# KMODOWN KLD owner. [${BINOWN}] 19# 20# KMODGRP KLD group. [${BINGRP}] 21# 22# KMODMODE KLD mode. [${BINMODE}] 23# 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: 28# 29# LINKS= /modules/master /modules/meister 30# 31# KMODLOAD Command to load a kernel module [/sbin/kldload] 32# 33# KMODUNLOAD Command to unload a kernel module [/sbin/kldunload] 34# 35# PROG The name of the kernel module to build. 36# If not supplied, ${KMOD}.o is used. 37# 38# SRCS List of source files 39# 40# SUBDIR A list of subdirectories that should be built as well. 41# Each of the targets will execute the same target in the 42# subdirectories. 43# 44# SYMLINKS Same as LINKS, except it creates symlinks and the 45# linked-to pathname may be relative. 46# 47# DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk) 48# 49# MFILES Optionally a list of interfaces used by the module. 50# This file contains a default list of interfaces. 51# 52# EXPORT_SYMS A list of symbols that should be exported from the module, 53# or the name of a file containing a list of symbols, or YES 54# to export all symbols. If not defined, no symbols are 55# exported. 56# 57# +++ targets +++ 58# 59# distribute: 60# This is a variant of install, which will 61# put the stuff into the right "distribution". 62# 63# install: 64# install the kernel module; if the Makefile 65# does not itself define the target install, the targets 66# beforeinstall and afterinstall may also be used to cause 67# actions immediately before and after the install target 68# is executed. 69# 70# load: 71# Load KLD. 72# 73# unload: 74# Unload KLD. 75# 76# bsd.obj.mk: clean, cleandir and obj 77# bsd.dep.mk: cleandepend, depend and tags 78# 79 80AWK?= awk 81KMODLOAD?= /sbin/kldload 82KMODUNLOAD?= /sbin/kldunload 83OBJCOPY?= objcopy 84 85TARGET_ARCH?= ${MACHINE_ARCH} 86 87.if !target(__initialized__) 88__initialized__: 89.if exists(${.CURDIR}/../Makefile.inc) 90.include "${.CURDIR}/../Makefile.inc" 91.endif 92.endif 93 94.SUFFIXES: .out .o .c .cc .cxx .C .y .l .s .S 95 96CFLAGS+= ${COPTS} -D_KERNEL ${CWARNFLAGS} 97CFLAGS+= -DKLD_MODULE 98 99# Don't use any standard or source-relative include directories. 100# Since -nostdinc will annull any previous -I paths, we repeat all 101# such paths after -nostdinc.
