linux/module.h：No such file or director
linux/mm.h：No such file or directory
linux/error.h：No such file or directory
linux/config.h：No such file or directory
asm/segment.h：No such file or directory
为什么会出现这样的错误？
不是说建立内核树就可以了吗
我是第一次开始学写驱动，请大家帮帮忙，多多赐教阿
还有，我试着按照 linuxdevicedriver3 里说的写的一个驱动
#include<linux/module.h>
#include<linux/kernel.h>
#include<linux/version.h>
#include<linux/types.h>
#include<linux/fs.h>
#include<linux/mm.h>
#include<linux/error.h>
#include<linux/config.h>
#include<asm/segment.h>
unsigned int test_major = 0;
static int read_test(struct inode *inode,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 void release_test(struct inode *inode,struct file *file,){
MOD_DEC_USE_COUNT;
}
struct file_operations test_fops = {
NULL,
read_test,
write_test,
NULL,
NULL,
NULL,
NULL,
open_test,
release_test,
NULL,
};
int init_module(void){
int result;
result = regster_chrdev(0,"test",&test_fops);
if(result < 0){
printk(KERN_INFO "test:can't get major number!\n");
return result;
}
if(test_major == 0)test_major = result;
return 0;
}
void cleanup_module(void){
unregister_chrdev(test_major,"test");
}
只要这样一个.c文件就可以了吗？
大家帮帮忙呵
急：gcc为什么找不到库文件？在线等
