linux / init.h：没有这样的文件或目录 [英] linux/init.h: No such file or direcotry
问题描述
#include< linux / init.h>
#include< linux / module.h>
#include< linux / kernel.h>
我浏览了周围，并尝试了其他路径，这些文件在浏览类似问题时应该是这样的，但迄今没有任何工作。最奇怪的是我已经使用这个模块了我被提供了启动器代码，这在顶部（我没有改变任何东西），它没有给我这个错误。虽然，显然后面的代码是不同的，但这似乎是目前最大的问题。
完整的代码如下：
#include< usr / unclude / linux / init.h>
#include< usr / include / linux / module.h>
#include< usr / include / linux / kernel.h>
/ *加载模块时调用此函数。 * /
int simple_init（void）
{
printk（KERN_INFOLoading Module\\\
）;
static LIST_HEAD（birthday_list）
struct birthday {
int day;
int month;
int year;
struct list_head列表;
};
struct birthday * ptr，* next;
struct birthday * bob;
struct birthday * judy;
struct birthday * josh;
struct birthday * lana;
struct birthday * jan;
bob = kmalloc（sizeof（* bob），GFP_KERNEL）;
bob - >天= 17;
bob - >月= 1;
bob - >年= 1990年
INIT_LIST_HEAD（& bob - > list）;
...
list_add_tail（bob - > list，& birthday_list）;
list_add_tail（judy - > list，& birthday_list）;
list_add_tail（josh - > list，& birthday_list）;
list_add_tail（lana - > list，& birthday_list）;
list_add_tail（jan - > list，& birthday_list）;
struct birthday * ptr;
list_for_each_entry（ptr，& birthday_list，list）{
kprintf（'％d /％d /％d \\\
'，ptr - > month，ptr - 日，ptr - >年）;
}
list_for_each_entry_safe（ptr，& birthday_list，list）{
list_del（& ptr-> list） ;
kfree（ptr）;
}
返回0;
}
/ *当该模块被删除时，此函数被调用。 * /
void simple_exit（void）{

我想你必须先安装像linux-headers - [内核版本]由apt-get然后您必须创建Makefile如下：
ifneq（$（KERNELRELEASE），）
＃从内核构建系统调用
lifo-objs：= main.o
obj-m：= lifo.o
else
KERNELDIR？= / lib / modules / $（shell uname -r）/ build
PWD：= $（shell pwd）
modules：
echo $（MAKE）-C $（KERNELDIR）M = $（PWD）LDDINC = $（PWD）/../包括模块
$（MAKE）-C $（KERNELDIR）M = $（PWD）LDDINC = $（PWD）/../包含模块
endif
clean：
rm -rf * .o *〜core .depend * .mod.o。*。cmd * .ko * .mod.c \
.tmp_versions * .markers * .symvers modules.order
depend .depend dep：
$（CC）$（CFLAGS）-M * .c> .depend
ifeq（.depend，$（通配符.depend））
包含.depend
endif
将上述Makefile中的KERNELDIR变量设置为适当的内核版本，默认情况下使用您运行的内核。如果您使用此Makefile，则需要将包含更改为以下格式：
#include< linux / init.h>
#include< linux / module.h>
#include< linux / kernel.h>
我认为内核模块开发使用标准内核从 Linus Torvalds git 更好。对于一些简单的内核模块，请参阅此。
I'm trying to build a kernel module for a class of mine and I'm getting a wall of errors, but at the top of said wall is the infamous 'No such file or directory' error. It seems to be the root of the problem. This not only seems to affect init.h, but also module.h and kernel.h. The first three lines of the program go as follows:
#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
I've looked around and tried other paths for where these files ought to be when browsing similar issues, but nothing has worked thus far. The strangest part is that I used this module already; I was provided starter code that had this at the top (I didn't change anything) and it didn't give me that error. Although, obviously the code after is different, but this seems to be the biggest problem at the moment.
The full code is as follows:
#include <usr/unclude/linux/init.h>
#include <usr/include/linux/module.h>
#include <usr/include/linux/kernel.h>
/* This function is called when the module is loaded. */
int simple_init(void)
{
printk(KERN_INFO "Loading Module\n");
static LIST_HEAD(birthday_list)
struct birthday{
int day;
int month;
int year;
struct list_head list;
};
struct birthday *ptr, *next;
struct birthday *bob;
struct birthday *judy;
struct birthday *josh;
struct birthday *lana;
struct birthday *jan;
bob = kmalloc(sizeof(*bob), GFP_KERNEL);
bob -> day = 17;
bob -> month = 1;
bob -> year = 1990;
INIT_LIST_HEAD(&bob -> list);
...
list_add_tail(bob -> list, &birthday_list);
list_add_tail(judy -> list, &birthday_list);
list_add_tail(josh -> list, &birthday_list);
list_add_tail(lana -> list, &birthday_list);
list_add_tail(jan -> list, &birthday_list);
struct birthday *ptr;
list_for_each_entry(ptr, &birthday_list, list){
kprintf('%d/%d/%d \n', ptr -> month, ptr -> day, ptr -> year);
}
list_for_each_entry_safe(ptr, &birthday_list, list){
list_del(&ptr->list);
kfree(ptr);
}
return 0;
}
/* This function is called when the module is removed. */
void simple_exit(void) {
printk(KERN_INFO "Removing Module\n");
}
/* Macros for registering module entry and exit points. */
module_init( simple_init );
module_exit( simple_exit );

I think you must first install something like linux-headers-[kernel version] by apt-get then you must create Makefile as following :
ifneq ($(KERNELRELEASE),)
# call from kernel build system
lifo-objs := main.o
obj-m := lifo.o
else
KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
modules:
echo $(MAKE) -C $(KERNELDIR) M=$(PWD) LDDINC=$(PWD)/../include modules
$(MAKE) -C $(KERNELDIR) M=$(PWD) LDDINC=$(PWD)/../include modules
endif
clean:
rm -rf *.o *~ core .depend *.mod.o .*.cmd *.ko *.mod.c \
.tmp_versions *.markers *.symvers modules.order
depend .depend dep:
$(CC) $(CFLAGS) -M *.c > .depend
ifeq (.depend,$(wildcard .depend))
include .depend
endif
set KERNELDIR variable in above Makefile to your appropriate kernel version, by default it use your running kernel. If you use this Makefile you need to change your include to following format:
#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
I think for kernel module developing use standard kernel from Linus Torvalds git is better. For some simple kernel module see this.
