刚开始学习linux下的驱动开发，书上的例子编译不了，大家帮忙看看

xiaobaiwen

这是《linux程序设计》第三版 18章的第一个例子
源码是这个：

/*
*    Hello world module.
*/
#include <linux/module.h>

#if defined(CONFIG_SMP)
#define __SMP__
#endif

#if defined(CONFIG_MODVERSIONS)
#define MODVERSIONS
#include <linux/modversions.h>
#endif

#include <linux/kernel.h>

int init_module(void)
{
    printk(KERN_DEBUG "Hello, kernel!\n");
    return 0;
}

void cleanup_module(void)
{
    printk(KERN_DEBUG "Good-bye, kernel!\n");
}

编译语句是：$ gcc -D__KERNEL__ -I/usr/src/linux/include -DMODULE -Wall -O2 -c hello.c -o hello.o

我的系统是openSUSE 11.0 一开始好像系统没有安装源码，提示一些头文件找不到
后来我从光盘中把源码装入，又有了如下的错误，
我在网上找了一下，好像有同样的问题，不过好像没有被解决，
大家帮帮忙，看看应该如何解决，
这么多错误提示，我一点头绪都没有！！！

错误提示：
$ gcc -D__KERNEL__ -I/usr/src/linux/include -DMODULE -Wall -O2 -c hello.c -o hello.o

怀疑楼主的kernel是2.6的
参考一下ldd3，写个Makefile编译吧
T-bagwell 发表于 2009-04-08 17:15

呵呵，我也遇到过，2.6模块编译方法变了

yel617

hello.c

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

MODULE_LICENSE("Dual BSD/GPL");

static int hello_init(void)
{
    printk(KERN_ALERT "Hello, Techshine !\n");
    return 0;
}

static void hello_exit(void)
{
    printk(KERN_ALERT "Goodbye, Techshine ! \n");
}

module_init(hello_init);
module_exit(hello_exit);

Makefile

MVTOOL_PREFIX = /usr/local/arm/3.4.1/bin/arm-linux-  
KERNEL_DIR = /home/sys/linux-2.6.20
MAKE_ENV = ARCH=arm     CROSS_COMPILE=$(MVTOOL_PREFIX)

#TARGET = hello.ko
obj-m += hello.o

all:
     make -C $(KERNEL_DIR) M=`pwd` $(MAKE_ENV) modules
# cp hello.ko /home/pr/hello

clean:
     -rm -rf *.o *mod* *.ko .cmem* .tmp*



参考下这个看看

meijusan123

大概 问题 有多情况的。
第一 你要看 是不是内核版本问题，不同版本 内核的结构体和api有所差别。
第二 你这是嵌入式还是普通linux内核驱动。
第三 最好是写个makfile来编译代码。
第四 就是看看 你的/usr/src/kernels下有没相关kernel编译使用的header文件啦。

avcodec

我现在在2.6内核下编译驱动程序也出现这个问题了。是linxu程序设计(第三版)的那个例子。那位老大来说几句。

T-bagwell

呵呵
主要是有人挖坟啊

dreamice

这么老的东西，也拿来搞，呵呵

T-bagwell

怀疑楼主的kernel是2.6的
参考一下ldd3，写个Makefile编译吧

Godbach

你用的什么内核版本，2.6下的编译方法改变了。建议看LDD3
