First write driver

For the first time, write the driver-general Linux technology-Linux programming and kernel information. For details, refer to the following. The first time I learned the write driver, I tried to write a driver according to linuxdevicedriver3.

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 ");
}

Can a device driver write such a. c file? (I really don't know. I didn't even mention such a complete driver example ),????
Then execute:
Gcc-O2-DMODULE-d1_kenel _-c test. c

Error:
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

Why? Why can't gcc find the lib file? I have installed linux-headers-
