c - 简单的Make文件错误

Question

我正在尝试创建一个简单的 make 文件并使用它来构建一个简单的 c 程序。环境是在virtual box中，使用最新版本的ubuntu。我已经下载了 ubuntu 的 linux 头文件，但仍然收到错误。

你好.c

#include <linux/init.h>
#include <linux/module.h>

static int hello_init(void) {
    printk(KERN_ALERT "TEST: Hello world, this is soliducode\n");
    return 0;
}

static void hello_exit(void) {
    printk(KERN_ALERT "TEST: Good byte, from soliduscode");
}

module_init(hello_init);
module_exit(hello_exit);

生成文件

obj-m += Hello.o

KDIR = /usr/src/linux-headers-4.2.0-16-generic

all: 
    $(MAKE) -C $(KDIR) SUBSIRS=$ modules

clean:
    rm -rf *.o *.ko *.mod.* *.symvers *.order

错误

您的内核配置似乎无效。

有文档说明如何在 Ubuntu 上构建自己的内核，例如 https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
