Unable to compile the simplest of kernel modules

[thejdev]

I'm running x86_64 gutsy on an AMD 64 bit dual core machine (1 GB RAM,200 GB SATA HDD) but I dont have an internet connection . I've installed the build-essential packages for gcc,g++ and libc6-dev that come along with the live cd and have installed the kernel headers package for kernel 2.6.22-14 that comes as a .deb package on the ubuntu website .
I tried to compile a simple hello world kernel module (see below) :


//hello.c in root folder

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

#if CONFIG_MODVERSIONS == 1
#define MODVERSIONS
#include <linux/modversions.h>
#endif

int init_module()
{
printk("\n\nHello world \n\n");
return(0);
}

void cleanup_module()
{printk("\n\nBye\n\n");}

Whoa someone's unhappy !

I'm not allowed an internet connection on my comp as I live in a hostel , so could someone please direct me how to get the build essential package for kernel headers through windows . I've been trying for over a week now , unsuccessfully

Hello,

Take a look at this module example.
http://ubuntuforums.org/showthread.php?p=3486457#post3486457

Note that "/lib/modules/$(uname -r)/build" is normally a symbolic link to /usr/src/linux-headers....

$ ls -l /lib/modules/$(uname -r)/build
lrwxrwxrwx 1 root root 40 2007-10-10 10:47 /lib/modules/2.6.22-14-generic/build -> /usr/src/linux-headers-2.6.22-14-generic

Study also the guides under "Driver and module programming" of this guide. (http://www.futuredesktop.net/kernel.html)
---- ---- ---- ---- ---- ---- ---- ----

Downloading packages for your offline system.

As you already know, you will need at least these components. (The examples are taken from my 32 bits Ubuntu)
$ apt-cache search linux-headers-$(uname -r)
linux-headers-2.6.22-14-generic - Linux kernel headers for version 2.6.22 on x86/x86_64

$ apt-cache search build-essential
build-essential - informational list of build-essential packages
---

Browse to http://packages.ubuntu.com/ and search for the package names.

Download the (.deb) packages for your system (is it a 64-bits Gutsy?)
Important: Take also all depending packages ! Eg. the "build-essential" pack has these dependencies.... (http://packages.ubuntu.com/gutsy/devel/build-essential), Ok?

Use the "dpkg -i" command to install the packages on your offline system.
$ sudo dpkg -i *deb

Maybe some of the packages lay on the installation CD too. I do not know.

Merry Christmas

So its not possible to compile a kernel module directly using the gcc command ..... I never knew .... Thanks a lot ...
