【Backup】编译可加载内核模块的Makefile

obj-m := test.o

KERNELBUILD := /lib/modules/`uname -r`/build

default:

@echo "  BUILD kmod"

@make -C $(KERNELBUILD) M=$(shell pwd) modules

clean:

@echo "  CLEAN kmod"

@rm -rf *.o Module.markers  modules.order

@rm -rf .depend .*.cmd *.ko *.mod.c .tmp_versions *.symvers .*.d

one example:

#include

#include

#include

MODULE_LICENSE("Dual BSD/GPL");

static int __init mod_entry_func(void)

{

        printk("hello world! is init ");

return 0;

}

static void __exit mod_exit_func(void)

{

printk("Hello world is exit\n");

return ;

}

module_init (mod_entry_func);

module_exit (mod_exit_func);

编译：make

加载：insmode test.ko

卸载：rmmode test

用printk输出的信息不显示在终端，若要查看，输入：

dmesg
