ldd3的第一个例子无法正确编译

fennyk

新手请问:
// test.c

#include <linux/init.h>

#include <linux/module.h>

MODULE_LICENSE("Dual BSD/GPL");



static int hello_init(void)

{

        printk(KERN_ALERT "Hello, world\n");

        return 0;

}



static void hello_exit(void)

{

        printk(KERN_ALERT "Goodbye, cruel world\n");

}



module_init(hello_init);

module_exit(hello_exit);


提示如下:

操作系统是Debian Linux,内核2.6.19.
请问如何解决编译问题?

12013396

请将第2章读完再来提问，谢谢。

BTW,请把目光从p16移到p17,你就会看到内核模块不是直接用gcc编译的了。
