我在debian etch上编译一个驱动程序报错，是很简单的一个init/cleanup程序，哪位大哥帮忙看一下吧，先谢谢了。。


源程序（程序应该没有问题，就是《linux程序设计》第三版第十八章的第一个例子程序）：

#include 

#if defined(CONFIG_SMP)
#define __SMP__
#endif

#if defined(CONFIG_MODVERSIONS)
#define MODVERSIONS
#include 
#endif

#include 

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

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


编译时的命令（也是书上写的编译方法）：

gcc -D__KERNEL__ -I/usr/src/linux-headers-2.6.18-4-686/include -DMODULE -Wall -O2 -c hello.c -o hello.o


下面是gcc报的错误：

linux-headers-2.6.18-4-686、linux-source-2.6.18包我都装了。另外，我google了一下，据说光安装这些包还不行，还要config？但是具体要怎么做呢？我目前是在自学《linux程序设计》第三版，现在看到第18章设备驱动程序，这个是这章上的第一个例子，目前我暂时还没时间去研究内核的东西，只是想先把这本书看完，先有个基本的概念。。。

第一， 你的 这段代码不太对，
第二， 你的 Makefile 不对。
具体原因去 http://blog.csdn.net/pottichu/archive/2007/11/19/1892245.aspx 看看。

module_init(init_module);
module_exit(cleanup_module);

我的建议是如果打算看看驱动，就去看LDD 3
