编译一个最简单的驱动程序,出现了太多错误,不知所措,求救!
编译一个最简单的驱动程序,出现了太多错误,不知所措,求救!--------------------------------------------------------------------------------
在一本书上原抄了一个类似helloworld的驱动程序,TestDrive.c
shell下执行以下命令进行编译: gcc -O2 -DMODULE -D__KERNEL__ -c TestDriver.C
出现了这么多错误(比较长,请耐心点帮我看看,谢谢)

***************************************************************
我的头文件是这样的:
****************以下是TestDriver.c程序的开头部分**********************
/*TestDriver.c*/
/*一个简单的字符设备驱动实例*/
#define __NO_VERSION__
#include <linux/modules.h>
#include <linux/version.h>
char kernel_version [] = UTS_RELEASE;
#define KERNEL
#include <linux/types.h>
#include <linux/fs.h>
#include <linux/mm.h>
#include <linux/errno.h>
#include <asm/segment.h>
****************************************************************
从出错信息中可以看到,/usr/include/linux/下面有很多.h文件都有错误,可是那都是系统自带的阿,我绝对没有改过,我装的是redhat9.0系统,内核版本是2.4.20-8
后面还有一些出错信息比如printk/register_chrdev/MOD_INC_USE_COUNT........没有定义,但我看了很多
驱动的例子,也特意包含了他们的所有头文件阿,
这只是一个最简单的例子,就有这么多问题,我要完成编写一个芯片可用驱动的任务痛苦+没有信心中...
谁能帮我指点一下,到底该怎么解决这么多错误?
谢谢! 你用的内核版本是2.4的还是2.6的??
如果2.4的kernel 那么linux/modules.h本来就不存在!!
ls /usr/include/`uname -r`/include/linux/modules.h
没有那个文件或目录
2.4的只有<linux/module.h>
另外头文件最好用GCC的 -I 选项指定! 应该有-I/usr/src/linux-*.*.*/include
