The number of users interested in building their own kernel achieves this because they have Ubuntu installed on their system, and please make minor kernel changes for that system. In many cases, the user is just looking for a kernel config switch.

The goal of this page is always to provide the user with as little information as possible directly to achieve the goal of developing and building a simple kernel modification and installation of the kernel. It is not intended as a guide to developing the Ubuntu kernel.

Create Environment

If you haven’t already built your method on the kernel, there are several packages that are required to build it successfully. You can install it with:

 sudo apt-get build-dep linux linux-image - $ (uname -r)

Unfortunately, not all of the functions listed above will install all required dependencies. The current version of the Goofy Disco Release requires the correct add-on packages.

 sudo apt-get is installed in libncurses-dev gawk flex bison libssl-dev openssl dkms libelf-dev libudev-dev libpci-dev liliberty-dev autoconf

If you can use Git, install it from:

```
 sudo apt-get load git 
```

The above command requires your platform to have the correct deb-src in /etc/apt/sources.list . An example of a dingo disco you must have:

 deb-src http://archive.ubuntu.com/ubuntu disco maindeb-src http://archive.ubuntu.com/ubuntu disco-updates main

Getting One Of Our Sources For The Ubuntu Version

how to compile kernel in ubuntu 11.10

There will of course be several different ways to get the kernel source. The two main routes are fully documented.

If you have the correct version of Ubuntu installed and would like to modify any kernel installed on your device, use the apt-get method (detailed below) to get the sources.

>However, just like you want to get the current global sources for the current Ubuntu version and then make changes to them, use this git method (described below) to take advantage of the sources.

Apt-get

The source code generated by a specific binary package can be obtained by requesting apt-get source . For example, to get the source code of the newly createdThe second core, you can use

 apt-get command line: linux-image-unsigned source code - $ (uname -r)

Git

All Ubuntu kernel sources are processed by git at the end. The source code for each tool is stored in its git repository at kernel.ubuntu.com . To get any local copy you can absolutely git-clone any release repository you are interested in, as described below.

 git clone git: //kernel.ubuntu.com/ubuntu/ubuntu-  .git

 git identical copy of git: //kernel.ubuntu.com/ubuntu/ubuntu-disco.git

Change Configuration

This step can be skipped if configuration changes are not normally required. The build process maintains configuration pertaining to various sub-configuration files. Probably the easiest way to change something here is to do the following:

 chmod a + x debian / ruleschmod a + x debian / scripts / *chmod a + x debian / scripts / misc / *LANG = C fakeroot debian / clean rulesLANG = C fakeroot debian / rules editconfigs # You call to iterate over all of them (Y, Exit, Y, Exit ..) or get a configuration complaint later

This will use the initial configuration for a specific archivethe texture / architecture supported when calling menuconfig to edit your own config file. Chmod is necessary because the way you build the source package will almost certainly lead to loss of executable sections in your scripts.

To keep your kernel “newer” than the current Ubuntu kernel your company is based on, consider adding a good local version modifier. At the end of the version number in most debian.master / changelog files, add one thing like “test1” before generating it. This will help determine which kernel it is running on, since it also uname -a relies on itself. Note that if a significant new kernel is released, Ubuntu will be newer than your own personal kernel (which will need to be rebuilt), so maintenance is considered necessary when upgrading. NOTE. Try not to use CONFIG_LOCALVERSION as it _fires_ the assembly.

Kernel Generation

Building the kernel is pretty straightforward. Change the working directory back to the root directory of the kernel buy tree, then enter the following commandsdy:

 LANG = C fakeroot debian / clean rules# build faster:LANG = C fakeroot debian / rules header binary binary common perarch binary# If you think you need low latency Linux tools, do the following:LANG = C fakeroot debian / binary rules

On a successful build, three .deb binary package images are created in the website directory above the build root directory. For example, when building the main kernel with version 4.8.0-17.19 on a useful AMD64 system, these three are four) (or.

 CD ...ls * .deb    linux-4.8.0-17_4.8.0-17.19_all.deb headers    linux-4.8.0-17-generic_4.8.0-17.19_amd64.deb headers    linux-image-4.8.0-17-generic_4.8.0-17.19_amd64.deb

in later versions you will also find the linux-extra- package, which the client should also install if available.

Testing The Most Important New Kernel

Install a 3pack TV (on your build system or another target system) by running dpkg -i and restarting: then

 sudo dpkg -i linux * 4.8.0-17.19 * .debsudo restart

Debug Symbols

It is sometimes useful to display debug symbols as well. Two additional steps may be required. Must be installed н the first pkg-config-dbgsym. Second, you need to set skipdbg = false when running your binary targets *.

 sudo apt-get install pkg-config-dbgsymLANG = C fakeroot debian / clean rulesLANG = C fakeroot debian / rules binaries-headers binary-common-binary-perarch skipdbg = false
