This guide describes how to compile your own kernel for Ubuntu. He will demonstrate both the orthodox “build with” process and the “make install” process with rationale, as well as the Debian alternative using “make-dpkg”. This is the descriptive version of this guide, see Compiling the Linux Kernel on Ubuntu 12.04 LTS for a quick overview. In each case, we start by installing a set of people dependencies:

sudo apt-get install git-core libncurses5 libncurses5-dev libelf-dev asciidoc binutils-dev linux-source qt3-dev-tools libqt3-mt-dev libncurses5 libncurses5-dev fakeroot build-essential kexec-tools failed kernel package makedumpfile kernel-wedge

Note: qt3-dev-tools and libqt3-mt-dev are required if you plan to “take full advantage of xconfig”, and libncurses5 and libncurses5-dev if customers plan to use menuconfig”. Then copy the kernel sources and wget:

wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.2.17.tar.bz2

tar -xjvf linux-3.2.17.tar.bz2 cd linux-3.2.17/

Customers are now in the upper right directory of the source tree i ra. The kernel runs in a default configuration based on the one provided by the people who mapped the kernel source distribution. It will include support for almost everything as it is designed to be used by caudillos and it is huge. In this form, it takes several minutes to compile and a little time to download. So, before a kernel can be designed, it must be configured. If you want to reuse any type of configuration from a running kernel, start by copying the current configuration stored in /boot:

cp -vi -r` /boot/config -`uname .config

Parse the user’s .config file with make in addition to the oldconfig flag. • Although the new options are almost always available in the kernel tree, you may still be prompted to choose whether or not to enable them. If you’re unsure, accept the defaults.

Create old configuration

Starting with kernel 2.6.32, the upgrade options now allow you to compile only those modules that you can actually use on your system. When prompted, doMake your selections as described above, otherwise press Enter to see the defaults.

How do I find my kernel source code?

The text source that generated the verbose binary package can usually be obtained using the apt-get source command. For example, to get a working kernel source, you can use the following command in full: apt-get place linux-image-unsigned-$(uname -r)

Create localmodconfig

The second step is to customize the kernel to suit your needs. You will most likely configure your build to work with ncurses using the menuconfig flag:

Create menu configuration

Is the Ubuntu kernel open source?

Ubuntu Linux kernels are open reference and can be downloaded but built. For each Linux kernel plan they support, the Ubuntu kernel developers maintain a series of fixes until those individual fixes are shipped upstream. They also support specific configuration.

Create xconfig

If you wish, you will be presented with a series of menus from which you can select the options you wish to add. For most places, you have three options: (blank) exit; (M) compile it, even if it’s a module, loaded only when the functionality might be needed; (*) compile it monolithically into the kernel, so it will most likely be there when most of the kernel is first loaded.

There are several things you can do that require reconfiguration:

Reduce typical kernel size by eliminating unnecessary gadgets. Is it useful for further kernel development? A small kernel takes much less time to compile and/or less time to load. In addition, there will probably beMore memory is available, resulting in fewer page breaks and faster compilation.

Save the web design required to use the components installed on your system. To do this without using almost everything possible, you need to know what device is installed on your system. There are many ways to find out.

Before we go too far, use the “General Menu Configuration” options, then the “Local Version” and “Automatically Add Version Info” options to add a suffix to the best basename so you can separate it from “vanilla” . – The core can distinguish. You can change the group version string for different configurations that you are also trying to distinguish in this company.

Assuming you have a running Linux program with a running kernel, there are a few other places where you can see what devices you have and what drivers are working.

Check the system log file, /var/log/messages, or use the person command, dmesg, to view messages printed by device drivers.when these types of products appear.

Use the lspci -vv command to get a list of hardware devices using the PCI bus.

Use the lsub -vv command to document hardware devices using USB.

Use the lsmod command to see which kernel modules are in use.

Look in /proc/modules for another representation of the modules used in .

Check /proc/devices to see which devices are recognized by the system.

Check /proc/cpuinfo to see what processor you have.

Open the event computers and read the labels on the components, I would say.

See hardware documentation for each system. If you know your motherboard, you should be able to refer to a manual that will tell you about the built-in peripherals.

Using currently available information and common sense, acquire a reasonable set of kernel system options together. Read the online help descriptions along the way (at least for almost all higher level trial options) to familiarize yourself with the choice of drivers and software components.Codes for the Linux kernel. p>
