<span id="Kernel-1"></span><h3 class="section">1.4 Kernel</h3>
<p>Kernel isn’t managed under the main repositories, even though you could package
one for your personal use. Here is an <a href="https://github.com/cemkeylan/kiss-repository/tree/master/personal/linux">example kernel package</a>,
which you will need to reconfigure for your specific setup if you want to make
use of it.
</p>
<span id="Obtaining-the-kernel-sources"></span><h4 class="subsection">1.4.1 Obtaining the kernel sources</h4>
<p>You can visit the https://kernel.org website to choose a kernel that you want
to install. Though only the latest stable and longterm (LTS) versions are
supported.
</p>
<div class="example">
<pre class="example">Download the kernel and extract it
$ wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.7.6.tar.xz
$ tar xf linux-5.7.6.tar.xz
Change directory into the kernel sources
$ cd linux-5.7.6
</pre></div>
<span id="Installing-dependencies"></span><h4 class="subsection">1.4.2 Installing dependencies</h4>
<p>In order to compile the kernel you will need to install some dependencies. You
will need <code>libelf</code> to compile the kernel. If you want to configure using the menu
interface you will also need <code>ncurses</code>.
</p>
<div class="example">
<pre class="example">The package manager asks to install if you are building more than one package,
so no need to run 'cpt i ...'
$ cpt b libelf ncurses
</pre></div>
<p>In the vanilla kernel sources, you need perl to compile the kernel, but it can
be easily patched out. You will need to apply the following patch. Patch was
written by <a href="https://github.com/E5ten">E5ten</a>. You will need to obtain and
apply the patch in the kernel source directory.
</p>
<div class="example">
<pre class="example">$ wget https://dl.carbslinux.org/distfiles/kernel-no-perl.patch
$ patch -p1 < kernel-no-perl.patch
</pre></div>
<span id="Compiling-the-kernel"></span><h4 class="subsection">1.4.3 Compiling the kernel</h4>
<p>Next step is configuring and building the kernel. You can check Gentoo’s <a href="https://wiki.gentoo.org/wiki/Kernel/Configuration">kernel configuration guide</a>
to learn more about the matter. Overall, Gentoo Wiki is a good place to learn
about configuration according to your hardware. The following will assume a
monolithic kernel.
</p>
<div class="example">
<pre class="example">$ make menuconfig
$ make
$ install -Dm755 $(make -s image_name) /boot/vmlinuz-linux
</pre></div>
