驱动书写-包含<linux/malloc.h>等头文件时时候报错~~

jkh

内核 linux-2.4.20-8

操作系统:redhat9 linux-2.4.20-8是redhat自带的


在包含<linux/malloc.h>等头文件时时候报错一大堆:

这时要编译的 文件first.c)

-------------------------------------------------------
#include<linux/module.h>
#include<linux/kernel.h>
#include<linux/malloc.h>

#include<linux/fs.h>/*
#include<linux/errno.h>
#include<linux/types.h>
#include<linux/proc_fs.h>
#include<linux/fcntl.h>
#include<asm/system.h>*/
-------------------------------------

用下面的 语句编译:
[root@jkh kernel]# gcc -o ceshi.o -DMODULE  -D__KERNEL__   -O -W -c first.c -I/usr/src/linux/include
[注:/usr/src/linux 为指向 /usr/src/linux-2.4.20-8的符号链接]
报错如下:

这个是否是版本依靠问题?该如何解决?

今天把redhat的内核由 2.4.20-8 升级到了 2.4.32 并在编译内核时取消了 版本依赖
include头文件时依旧报错如下:

cc.c 的文件内容为:


------------------------------------------------------------------------
/*cc.c*/
#define __NO_VERSION__

#include<linux/module.h>
------------------------------------------------------------------------



我是菜鸟........刚学驱动书写,查了不少的资料,觉得不是版本依赖 引发的问题,是否是我的gcc版本不兼容(我的gcc是renhat自带安装上去的)?
但如果是 gcc 版本问题的话,为何在2.4.20-8内核下也存在问题?并且在2.4.20-8内核 include<linux/module.h>这句不会出问题,<linux/fs.h>才报错了.
(注:在2.4.20-8内核下我已经成功编译了hello.o)

还是其他问题??
实在想不出解决问题的思路.人门难,难于上青天~各位高手如能指点一二~不胜感激.

希望和各位有兴趣的朋友共同学习
