    If you see an Ubuntu error while compiling kernel modules on your PC, you need to check out these repair tips.

    If you are not picky, you can install malware on the appropriate PC - Ubuntu.

    Linux System Operations, including Ubuntu, uses modules to enhance the new System Operations feature. If you run a small business in your branch in addition to Ubuntu desktops, chances are you don’t have an IT team installing such modules. If you understand the simple steps of compiling source code and then adding modules to the Ubuntu kernel, you should be able to easily run modules on your current workstations.

    In the search bar, click Ubuntu, dash and wide Terminal. Click the terminal icon to open that command terminal.

    Enter each of the following commands to determine your own kernel version, then write down the version:

    Download the base module code and change to its directory. If the help code is in / home / bob / source / module, the “module” number is the name of the module, then enter the following command to navigate to that directory:

    Just create a Makefile for the module by typing the following basic command:

    Enter the attached text in the Makefile, where “module” is the name of your course, then press Ctrl-X to exit the text editor:

    Insert a module from the kernel with the following hint, where “module.ko” is an extended module:

    Most end users interested in building their own kernel do this because Ubuntu is installed on their entire system and want to make small changes to their ownthe kernel for this system. In many of our cases, the user just wants to change the kernel configuration.

    The motivation for this page is to provide this user with a minimum of information so that he can usually achieve the goal of simply replacing the kernel, building and installing its kernel. This should never be a definitive guide to the Ubuntu development kernel.

    Create Environment

    If you have not yet built a real kernel on your system, some packages are usually required to build successfully. You can install it with:

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

    Unfortunately, the above does not install all useful dependencies. The current version of Disco Goofy requires slightly more of the following packages.

    •  sudo apt-get install libncurses-dev gawk fold bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev liliberty-dev autoconf 

    If you are traveling to become git, install the site via:

    •  sudo apt-get install git 

    compile kernel modules ubuntu

    The Beyond command requires your system to have the correct deb-src lines in /etc/apt/sources.list . For example, on Disco Dingo you should have

    Getting The Source Code For The Ubuntu Version

    Modify the makefile to replace each occurrence of helloWorld and therefore kernelRead with the adventure names you want to create.Compile the themes by running make on the list where the modules are located.Now become superuser by clicking.

    There are several ways to view the kernel sources. The most important torque paths are documented here.

    If most people have some version of Ubuntu installed and want to make changes to a kernel that is almost certainly installed on your system, use one of our apt-get methods (detailed below) to get the sources.

    However, if you think you are getting the most out of the main data sources for the Ubuntu model you are using and deviating from them, use the Git secrets (detailed below) to get the basics. Source


    The code that generates a specific new binary package can be ordered using the command apt-get source . For example, to get the source code for most working kernels, you can use the command:

     apt-get present linux-image-unsigned - $ (uname -r) 


    All Ubuntu kernel ingestion is handled under git . The source for each version is stored in its own Git repository, which reports at.

    •  git duplicates git: //  .git 
    •  git clone git: // git 

    Change Configuration

    This step can be skipped if no configuration changes are required. The assembly process uses a design assembled in various subconfiguration files. The easiest way to help you change something here is to hurry:

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

    This will use the current configuration for each supported architecture / option and phone menu configuration to change the file configuration. Chmod is necessary because IT loses the executable bits of these scripts due to the way the source package is created.

    To make your neck core “newer” than it isAn arty Ubuntu kernel that you rely on, consider adding a local translation modifier. Before compiling, add something like “+ test1” to the end of the first version number in the debian the.master / changelog directory. This will help you identify your kernel while it is running so that it also appears in uname -a . Please note that the re-released Ubuntu kernel will be newer than your kernel (pending regeneration), so be careful when upgrading. NOTE: do not try to use as config_localversion, this important _ will break compilation.

    Building The Main Kernel

    Building the kernel is very simple. Change the working directory to the root cause from the kernel source, then enter the following commands:

    •  LANG = C fakeroot debian / clean rules# build faster:LANG = C fakeroot debian / rules binary headers binary-generic binary-perarch# If you need Linux tools or a low latency kernel, use roaming instead:LANG = C fakeroot debian / binary rules 

    If the installation is successful, a set will be created in the directory above the new build root directory.From three or more binaries of the .deb package. An example of building a kernel with the plan “4.8.0-17.19” on an amd64 system, several of these (or four) .deb .packages. will be produced:.

    • 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

    On subsequent startup, you will also find an additional Linux package, which you should also install if available.

    Testing A New Kernel

    Install all three packages (on your home build system or on a variable target system) using dpkg -i, but also restart: dpkg

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

    Debug Symbols

    It is sometimes useful in the market to have well-designed debug symbols. Two more steps are required. The first pkg-config-dbgsym must be installed. Second, when binary targets * are met, owners should add skipdbg = false.

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