内核模块的问题

panzhenjie

/*hello.c*/
#define MODULE
#include<linux/module.h>

int init_module(void)
{
        printk("Hello, world\n");
        return 0;
}

void cleanup_module(void)
{
        printk("Goodbye cruel world\n");
}
然后
gcc -c hello.c
然后
insmod ./hello.o
./hello.o: kernel-module version mismatch
        ./hello.o was compiled for kernel version 2.4.20
        while this kernel is version 2.4.20-8.
这个要怎么办阿?

模块不是这样编译的

mozilla

gcc -c test.c -D__KERNEL__ -include /usr/src/linux/include/linux/modversions.h -I/usr/src/linux/include

我在自己的机器上用了
[root@localhost code]# gcc -c hello.c -D__KERNEL__ -include /usr/src/linux-2.4.20-8/include/linux/modversions.h -I/usr/src/linux-2.4.20-8/include

[root@localhost code]# insmod hello.o
Warning: loading hello.o will taint the kernel: no license
  See http://www.tux.org/lkml/#export-tainted for information about tainted modules
Module hello loaded, with warnings
终于能加载这个模块了,当然rmmod hello也是成功的,然而却没有预料中hello , world的输出,这是怎么回事阿?

在终端下看不到,在控制台下就能看到了.

抱歉，什么是控制台啊？要怎么打开控制台？
