linux 2.6下编译最简单的hello.ko驱动

1.下载kernel源码 http://www.kernel.org/
2.配置内核
luther@gliethttp:~/work/kernel/linux-2.6.22.14$ make oldconfig
luther@gliethttp:~/work/kernel/linux-2.6.22.14$ make prepare
luther@gliethttp:~/work/kernel/linux-2.6.22.14$ make scripts 否则提示：MODPOST 1 modules /bin/sh: scripts/mod/modpost: not found
3.写测试程序hello.c
//luther@gliethttp:~/work/kernel/module_drivers/hello$ vim hello.c
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/init.h>

static int init_hello_4(void)
{
   printk(KERN_ALERT "Hello, world 4 ");
   return 0;
}

static void cleanup_hello_4(void)
{
   printk(KERN_ALERT "Goodbye, world 4 ");
}

module_init(init_hello_4);
module_exit(cleanup_hello_4);
