Simple Make File Error

I am trying to create a simple make file and using it to build a simple c program. The environment is in virtual box using the newest version of ubuntu. I have already downloaded the linux headers for ubuntu but still getting the error.

Hello.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);

Makefile

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

Error

Solution

  • It looks like your kernel config is invalid.

    There is documentation how to build your own kernel on Ubuntu, e.g. https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
