This blog post will help you if you get an error code while compiling and installing the kernel on Ubuntu. Get one of the latest kernels at kernel.org.Check the kernel.Extract the main kernel tarball.Copy your existing Linux kernel configuration file.Compile and build the Linux 5.6 kernel.Install Linux Kernel and Adventure (Drivers)Update your grub config.
What is compiling a kernel?
Yes, building a kernel from a database usually means downloading the source code. If you want to change any source code (most non-programmers usually don’t). Kernel configuration (which functions / modules / drivers to include, etc.) Compile.
Most buyers interested in building their own kernel only do so because they have Ubuntu installed on their system and want to go back to slightly modifying their kernel for that system. In many legal cases, the user just wants to get it.T customize kernel changes.
The purpose of this page is to provide this user with a minimum of related information to achieve your current goal – to easily switch to a kernel, build it with your kernel installed. It was never intended to be the final highlight in Ubuntu kernel development.
If you haven’t compiled the best kernel on your system yet, it will take many packages before you can successfully build it. You can install it at the end with:
sudo apt-get build-dep a linux systemunix linux-image - $ (uname The -r)
Unfortunately, not all of the dependencies recommended above are installed. The current version of Disco Goofy requires the following additional suggestions.
sudo apt-get install libncurses-dev gawk extend bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf
If you are going to use Git, install it from here:
sudo apt-get install git
The atop command requires the system to get the correct deb-src lines from /etc/apt/sources.list . For example, in a disco, your dingo should have:
deb-src http: // archive.ubuntu.com/ubuntu main discodeb-src http://archive.ubuntu.com/ubuntu disco-updates home
Getting The Source Code For The Ubuntu Version
How do I build and compile a Linux kernel?
Step 1: Download the source code.Step 2: extract the source code.Step 3: Install the required packages.Step 7: Configure the kernel.Step 5: Build the actual kernel.Step 6: Update the bootloader (optional)Step 7: reboot and check your kernel version.
There are several ways to get the kernel sources. The two main routes are documented here.
How do I recompile my kernel?
Load an existing stablenew version from kernel.org.Unpack.Copy the classic config (do this)Use a terminal-driven configuration tool.Compile the kernel with Clang (remove CC to compile with gcc – the standard C compiler)Install the kernel.Update rude.Start over.
In general, when we have installed Ubuntu of your choice and you want to make changes to the kernel that is permanently installed on your system, use the apt-get method (described below) to get the sources.
However, if you want to get the most up-to-date help sources for the Ubuntu exception you are using and make some changes, use the Git systems (details below) for solutions.
Should you compile your own kernel?
Compiling your own kernel allows you to make sure that you are involved in the kernel development processes, be it simple things, most of which are like providing PCI / USB device IDs for just one driver. the whole battle for kernel development.
The source code that generated a specific binary package can be called using the apt-get
apt-get base linux-image-unsigned - $ (uname -r)
The entire Ubuntu kernel base is managed via git . The source code for each version is stored in its own Git repository at kernel.ubuntu.com . To get local For replication, you can simply clone the repository for the version you are interested in often simply using git clone current as shown below.
git duplicates git: //kernel.ubuntu.com/ubuntu/ubuntu-
git clone git: //kernel.ubuntu.com/ubuntu/ubuntu-disco.git
Frequent Configuration Changes
This step can be skipped if a configuration change is not required. The build process uses a configuration made up of many types of subconfig files. The easiest way to change anything here is to work:
chmod a + x a + x debian / ruleschmod debian / scripts / *chmod a + x debian / scripts / misc / *LANGUAGE = C fakeroot debian / custom rulesLANG = C fakeroot debian / rules editconfigs # You must go through all of them (Y, Exit, Y, Exit ..) or get a configuration complaint later
This will use the current configuration for each supported architecture / flavor and the menuconfig names to edit the configuration file. Chmod is necessary because the source code from which the package is built loses the executable bits of those particular scripts.
To make the current kernel “newer” than the default Ubuntu kernel you are in the first place, consider adding a local modifier. Manually add something like “+ test1” to the end of the first version number in debian.master / changelog before creating it. This allows your kernel to be identified when it is running, as it also appears in uname -a . Note that there is a new Ubuntu kernel that is newer than your kernel (which will need to be rebuilt), so be careful when upgrading. NOTE. Don’t try to use CONFIG_LOCALVERSION, as it will _ break_ the build.
Building The Kernel
Building the kernel is pretty straightforward. Change the working directory to the kernel source tree, then enter the following commands:
LANGUAGE = C fakeroot debian / clean rules# build faster:LANGUAGE = C fakeroot debian / rules binary headers binary-common-binary-prar# if families need Linux tools or kernels, low latency is used instead:LANG = C fakeroot debian / binary rules
If the extension was successful, consider creating multiple Their .deb package binaries in the above directory to improve the root directory. For the following example kernel build with version “4.8.0-17.19” on AMD64 system, these three (or four) .deb softwares will be created:
CD ..ls * .deb Linux-headers-4.8.0-17_4.8.0-17.19_all.deb Linux-headers-4.8.0-17-generic_4.8.0-17.19_amd64.deb linux-image-4.8.0-17-generic_4.8.0-17.19_amd64.deb
When configuring versions, you will also find a reliable Linux add-on package that should also be used during installation.
Testing Different Kernels
Install all three packages (on this build system or on a specific target system) using dpkg -i later and restart your computer:
sudo dpkg -i linux * 4.8.0-17.19 * .debrestart sudo
It is sometimes useful to create such debug symbols. Two more steps are required. The first pkg-config-dbgsym package must be installed. The second time you run binary targets * you need to add ‘skipdbg = false’.
How to compile the Linux kernel?
You will need to install the following packages around Debian or Ubuntu Linux to help compile the Linux kernel: git: a fast, scalable, distributed version control program. You can get the latest resource code using the git command. False root? A tool for simulating superuser rights.
sudo apt-get buy pkg-config-dbgsymLANGUAGE = C fakeroot debian / custom rulesLANG = C fakeroot debian / rules
The instructions given here are a very important recipe for getting the sources and then creating them. If developing your kernel is about more than just configuring, here are a few things to watch out for:
