<<Include(Kernel/Action/ObtainTheSource)>> == Obtaining the source for an Ubuntu release ==

There are a number of different ways of getting the kernel sources. The two
main ways will be documented here.

If you have installed a version of Ubuntu and you want to make changes to the
kernel that is installed on your system, use the '''apt-get''' method (described
below) to obtain the sources.

However, if you wish to get the most up to date sources for the Ubuntu release
you are running and make changes to that, use the '''git''' method (described
below) to obtain the sources.

=== apt-get ===

The source code which generated a specific binary package may be obtained using
the {{{apt-get source <package>}}} command. For example to obtain the source
for the currently running kernel you can use the command:

    {{{
apt-get source linux-image-$(uname -r)
}}}

=== git ===

All of the Ubuntu Kernel source is maintained under {{{git}}}. The source for
each release is maintained in its own git repository on {{{kernel.ubuntu.com}}}.
To obtain a local copy you can simply git clone the repository for the release
you are interested in as shown below.

    {{{
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-<release>.git
}}}

For example to obtain the maverick tree:

    {{{
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-maverick.git
}}}


== Building the kernel ==

Building the kernel is quite easy. Change your working directory to the root
of the kernel source tree and then type the following commands:

    {{{
fakeroot debian/rules clean
fakeroot debian/rules binary-generic
}}}

== See also ==

The above instructions provide a very simple recepie for obtaining the sources
and then building them. If you are going to be doing more kernel development
than simple configuration changes you may want to look at:

[[https://wiki.ubuntu.com/Kernel/Action/GitTheSource|Git the source]]

This page will describe how to easily build the kernel.

The majority of users that are interested in building their own kernel are doing so because they have installed Ubuntu on their system and they wish to make a small change to the kernel for that system. In many cases the user just wants to make a kernel configuration change.

The purpose of this page is to give that user a minimum amount of information for them to meet the goal of making a simple change to the kernel, building it and installing their kernel. It is not intended to be the definitive guide to doing Ubuntu kernel development.
