hello world。编译错误

[21lyw]

高手指点一下吧，找了好多帖子也没解决

return 0;
}

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

module_init(hello_init);
module_exit(hello_exit);

LDD3上的makefile。2.6内核的编译有点奇怪，我也遇到过类似的问题，编译出了一堆LINUX自带的文件的错误。用LDD3的编译文件就OK了。你试试看。

看了你的错误，不太清楚原因，但我可以给你一个解决的思路。
1、正确的编译内核树。
2、严格区分2.4版本与2.6版本。
3、正确配置环境变量。
我就是这么做的，基本没有遇到问题就成功了，没有遇到你的现象。
