急：一个linux字符驱动的编译问题,关于file_operations

一个简单的字符设备程序，大致如下
#include <linux/fs.h>
#include <linux/module.h>
#include <linux/kernel.h>

struct file_operations test_fops = {
read :read_test;
write write_test;
open:open_test;
release:realse_test;
};
static int read_test(struct inode *node,struct file *file,char *buf,int count)
static int write_test(struct inode *inode,struct file *file,const char *buf,int count)；

static int open_test(struct inode *inode,struct file *file )；

void init_module()
{
}
void clean_module()
{

}



什么也没做，编译用 gcc -DMODULE -D_KERNEL_ test.c

老是说storage of test_fops size isn\'t known ,
我在我rh9 的/usr/include/linux/fs.h里没找到file_operations 的定义，在/usr/src/linux-2.4.8-20/include/linux/fs.h里有file_operations 的定义，但我如果指出库文件路径/usr/src/linux-2.4.8-20/include,就由很多和多的fs.h里的错误出来，
问题比较低级，但我不知道为什么，大家救救我吧

代码
# define __NO_VERSION__
# include <linux/module.h>
# include <linux/fs.h>
# include <linux/kernel.h>

struct file_operations test_fops= {
 read : read_test,
 write: write_test,
 open: open_test,
 release: release_test,
 };
unsigned int test_major = 0;

static int read_test(struct inode *node,struct file *file,

char *buf,int count)

{


int left;

if (verify_area(VERIFY_WRITE,buf,count) == -EFAULT )

return -EFAULT;

for(left = count ; left > 0 ; left--)

{

__put_user(1,buf,1);

buf++;

}


return count;

}



static int write_test(struct inode *inode,struct file *file,const char *buf,int count)

{

return count;

}



static int open_test(struct inode *inode,struct file *file )

{

 return 0;

}


static void release_test(struct inode *inode,struct file *file )
{
;
}


 

int init_module(void)

{

int result;
prinrtk(\"<1>hello world\");

result = register_chrdev(0, \"test\", &test_fops);

if (result < 0) {

printk(\"test: can\'t get major number \");

return result;

}

if (test_major == 0) test_major = result;

return 0;

}



void cleanup_module(void)

{

prinrtk(\"<1>bye bye\");

   unregister_chrdev(test_major, \"test\");

}



错误：

我在我rh9 的/usr/include/linux/fs.h里没找到file_operations 的定义，在/usr/src/linux-2.4.8-20/include/linux/fs.h里有file_operations 的定义，但我如果指出库文件路径/usr/src/linux-2.4.8-20/include,就由很多和多的fs.h里的错误出来.

报警信息:

我用了-I/usr/src/linux-2.4.20-8/include\\ ,为什么n file included from /usr/include/linux/fs.h:23,好奇怪.

我刚开始时也出现过此错误，我把usr/include下的linux链接文件重新链接产生新的，再编译时就没有这些错误了。

这位大哥，您是用的自己编译的内核吧？
如果是这样，您需要制定头文件路径到新内核。或者修改/usr/inlucde/linux，使其链接到新内核。

谢谢大家，这个问题解决了，主要是我的makefile文件写的格式不对
，并没有执行-I/后的路径，而继续采用默认路径的问题。就是TAB键出了问题。
