  obj-m:= hello.o#模块名称是hello.c

  obj-m := hello.o # Module Name is hello.c

  KDIR:=/lib/modules/$(shell uname -r)/build

  KDIR := /lib/modules/$(shell uname -r)/build

  全部:$(MAKE)-C $(KDIR)M = $(PWD)个模块

  all: $(MAKE) -C $(KDIR) M=$(PWD) modules

  clean:$(MAKE)-C $(KDIR)M = $(PWD)clean $(RM)Module.markers modules.order

不能保证头文件始终位于/usr/src目录中，但可以肯定地位于/lib/modules目录中.

its not guaranteed that headers file will always be located in /usr/src directory, but it will surely be located in /lib/modules directory.

• 确保系统具有最新的头文件

找出要显示的头文件 运行`

to find out which header files to be present run `

uname -r

uname -r

在终端上，输出将类似于

on terminal, output will be like

3.5.0-17-generic

运行安装头文件

sudo apt-get install linux-headers-$(uname -r)
