GNU/Linux openSUSE Build Kernel from Source Code Guide

Hi! The Tutorial shows you Step-by-step How to Download, Build and Install a Custom New Vanilla Kernel from Source Code on openSUSE 42.x-Leap/15.x-Leap/Tumbleweed GNU/Linux Desktop.

Especially relevant: this openSUSE Kernel Setup make use of the original Linux Kernel Source Code.

Again this tutorial make it the Easy Way and so is intended especially for Beginners.

Important to know how this Setup does Not change your existing System and so in any case you will be able to startup with the current Kernel from the GRUB Splash Screen.

For further advanced Kernel Configuration instructions you may see the Linux Kernel Documentation.

Finally, for a Non Bootable System before see: How to chroot on openSUSE GNU/Linux Tutorial.

   And Reboot:

   sudo reboot

   Then play:

   sudo zypper in -t pattern devel_basis

   And again:

   sudo zypper in bc openssl openssl-devel dwarves rpm-build libelf-devel elfutils-libelf-devel

   In case you are prompted confirm the setup with “1”.

2. 2. Making Target Directory

   Now make the Target Folder
   With:

   Downloading Linux Kernel for openSUSE
   Grab the tar.xz or tar.gz Archive from the List.
   If uncertain about what is a safe choice then opt for the latest Longterm release.

4. 4. Extracting Linux Kernel Archive

   Then Extract Linux Kernel into the target Directory
   First, access it:

   cd ~/kernel

   Then to untar the downloaded Kernel Source into the current Folder run:

   tar -xafv ~/Downloads/linux*.tar.xz

   Or in case of a tar.gz Archive use instead:

   tar -xvzf ~/Downloads/linux*.tar.gz
