Question

我正在linux下构建一个示例内核模块。模块源是“在内核树之外”。我从git获得了内核源代码树。但是配置内核需要时间。所以此刻我只是想针对我的发行版提供的内核头文件构建模块。

我的Makefile：

KVERSION=$(shell uname -r)
   PWD := $(shell pwd)
   all:
           make -C /lib/modules/$(KVERSION)/build/  M=$(PWD) modules
   clean:
           make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean


   $(info Building with KERNELRELEASE = ${KERNELRELEASE})
  obj-m := hello.o

但是停止报告我找不到等，这意味着找不到标题。

但文件在那里：

 $ls /lib/modules/$(uname -r)/build
 $arch  block  crypto  drivers  firmware  fs  include  init  ipc  kernel  lib  Makefile             Makefile.common  mm  Module.symvers  net  samples  scripts  security  sound  System.map  tools  usr  virt

我猜这是一个微不足道的问题。但我仍然无法找到解决方案。

提前致谢。

编辑：错误：

我认为你打算这样做

#include <linux/module.h>

而不是

#include <linux/modules.h>

构建“源外树”内核模块
