解决方法；
我看的方法是从网上看到的看到的。呵呵
1）先把我实验正确的方法贴出：The file include/linux/config.h has been removedfrom 2.6.18 kernel. So remember this if you build your favoritemodule against the new 2.6.19 kernel and you get an error。 Thatsbecause there is no more include/linux/config.h file in 2.6.19.This is from the Changelog:

sh: Kill off remaining config.h references.

A few of these managed to sneak back in, get rid of them once
and for all.

解决方法：
The reason I posted this is for people who have the kernel sourcesinstalled and are trying to build a module against the sources andare getting the error I mentioned. You wouldn't be trying to builda module for the 2.6.19 kernel unless you had the sourcesinstalled.

Actually there is not much to the file:

Code:

#ifndef _LINUX_CONFIG_H
 
#define _LINUX_CONFIG_H
 

 
#include <linux/autoconf.h>
 
 
 
#endif

So if you have problems you could probably just add to code here toyour module.c file.



我也就是和上面的一样，但是程序还是不认上面的补丁程序；所以，我亲自手动把所有包含config.h的源文件改成autoconf.h。这样就没有出错了。但是还有人说2.6.23后没有了autoconf.h了。那就需要再先看看下面的方法有用没?

2)well the .h files are not from the main kernel package ,they arefrom the devel package(unless you built it yourself)

if kernel-devel(or -source depending on distro) isn't installedthere wouldn't be any useful includes
