本文介绍了一个用于嵌入式Linux环境下驱动开发的简单Makefile配置示例，详细展示了如何使用交叉编译工具链进行模块编译，并提供了编译、清理等操作的脚本命令。

#################################################################
# file name: Makefile
# A simple Makefile for driver
# by Late Lee at www.latelee.org
# based on LDD3 and other guys works
# copyleft @ 2010
#

#################################################################
### nothing, just for fun
OFFSET=\x1b[21G   # 21 col
COLOR1=\x1b[0;32m # green
COLOR2=\x1b[1;35m #
COLOR3=\x1b[1;31m # red
RESET=\x1b[0m

 
CLEAN_BEGIN=@echo -e "$(OFFSET)$(COLOR2)Cleaning up ...$(RESET)"
CLEAN_END=@echo -e "$(OFFSET)$(COLOR2)[Done.]$(RESET)"

 

MAKE_BEGIN=@echo -ne "$(OFFSET)$(COLOR1)Compiling ...$(RESET)"
MAKE_DONE="$(OFFSET)$(COLOR1)[Job done!]$(RESET)";
MAKE_ERR="$(OFFSET)$(COLOR3)[Oops! Error occurred]$(RESET)";

### nothing end here

 

CROSS_COMPILE=mipsel-linux-
CC := $(CROSS_COMPILE)gcc
LD := $(CROSS_COMPILE)ld

 

######### DEBUG部分

#DEBUG = y

ifeq ($(DEBUG), y)
	DEBFLAGS = -O -g
else
	DEBFLAGS = -O1

endif

 

# sth wrong here, don’t know why

#EXTRA_CFLAGS += $(DEBFLAGS) -I$(LDDINCDIR)

 

#########驱动模块名称以及源文件部分
# module name here
MODULE = attr
# obj-m = module
# obj-y = into kernel
# foo.o -> foo.ko

ifneq ($(KERNELRELEASE), )
	obj-m := $(MODULE).o
# 驱动源代码文件，.o形式
# your obj file(s) here
	$(MODULE)-objs := sysdemo.o
else
	KERNELDIR ?= /home/xiaoge/sdb1/ralink/MT7620/RT288x_SDK/source/linux-2.6.36.x
	PWD := $(shell pwd)
##########真正编译部分，添加了if语句
all:
	$(MAKE_BEGIN)
	@echo
	@if \
	$(MAKE) -C $(KERNELDIR) M=$(PWD) modules;\
	then echo -e $(MAKE_DONE)\
	else \
	echo -e \
	$(MAKE_ERR)\
	exit 1; \
	fi
endif

#####这个clean把生成的杂七杂八文件都删除，可用ls –al查看
clean:
	$(CLEAN_BEGIN)
	rm -rf *.cmd *.o *.ko *.mod.c *.symvers *.order *.markers .tmp_versions .*.cmd *~
	$(CLEAN_END)

########伪目标部分
install:
	@echo -e "$(COLOR3)                   Note:"
	@echo -e "To install or not install,that is a question.$(RESET)"
modules:
	@echo -e "$(COLOR3)Do not need to do this.$(RESET)"
modules_install:
	@echo -e "$(COLOR3)Do not need to do this.$(RESET)"
.PHONY: all clean install modules modules_install
############# Makefile end here
