ismod一个模块时出错

wcw

我的hello如下：
#include <linux/kernel.h>
#include <linux/module.h>
#if CONFIG_MODVERSIONS==1
#define MODVERSIONS
#include <linux/modversions.h>
#endif
int init_module()
{  
printk("<1>hello world !\n");
    printk("<1>I have runing in a kernel mod! \n");
    return 0;
}
void cleanup_module()
{  
printk("<1>I will shut down myself in kernel mod!\n");
}
然后gcc -O2 -DMODULE -D__KERNEL__ -I/usr/src/linux-2.6.15/include -c hello.c （少了-O2还不行）
接着insmod -f hello.o时显示：
[root@localhost device]# insmod -f hello.o
insmod: error inserting 'hello.o': -1 Invalid module format
不知是什么错误?

@fei

The <filename.o> was the old module format for kernel 2.4 and older versions. 2.6 kernel uses new format for modules. Each moodule is ended with .ko .

Have a look of your hello directory, see if there is a file called hello.ko . This is the module you should insert.
