linux内核模块的小问题

[wang12zhe]

一个hello.c的小程序
#include <linux/init.h>
#include <linux/module.h>

MODULE_LICENSE("GPL");

int hello_init()
{
printk(KERN_WARNING"Hello World %d!\n",year);
return 0;
}

void hello_exit()
{
printk("Hello Exit!\n");
}
module_init(hello_init);
module_exit(hello_exit);




makefile如下：
obj-m : = hello.c
全部是模仿一本书的例子。执行命令：
make -C /usr/src/linux-headers-2.6.38-8 M=$(pwd)modules

出现如下错误：
a123@a123-virtual-machine:~/lx/linux_shebeiqudong$ make -C /usr/src/linux-headers-2.6.38-8 M=$(pwd)modules
make: Entering directory `/usr/src/linux-headers-2.6.38-8'
ERROR: Kernel configuration is invalid.
include/generated/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.

求解，不胜感激

ERROR: Kernel configuration is invalid.
内核配置无效，
include/generated/autoconf.h or include/config/auto.conf are missing.
上面的文件没有
最好先配置编译一下内核，似乎这个内核的一些文件是在编译过程中生成的。
