This guide will help you when you see debian-Compile-Kernel-Module. To develop a kernel module, you need the source code and headers of a working kernel. If you are trying to distribute Linux, you already have it. Otherwise, you can get the corresponding kernel source at kenel.org. To mount the linux-header package on Debian or Ubuntu Linux, run this command even as root.
I’m trying to create a Debian kernel module on 9.SetI am using the required packages with
sudo install build-essential linux-headers-4 apt-get.9.I get 0-5-amd64but the following error when trying to compile the module:
> domake -C /lib/modules/4.9.0-5-amd64/build ModuleMake[1]: m=/home/sven/tmp/kernel enter website directory '/lib/modules/4.9.0-5-amd64/build'make[1]: No *** rules for target "modules".

/lib/modules/4.9.0-5-amd64/buildcatalog. .Actually .this .directory is .empty….Probably a newbie question, but do people know how to fix this?The required sources for the kernel module code are also required, as the corresponding makefiles are listed below.

There are two reasons for this choice. First of all, it can improve memory usage because kernel code, even if never used, doesn’t need memory for anything (and never “goes down” to swap because that’s the specific RAM it uses), which can degrade overall system performance. A kernel, locally released, can also limit the risk of security issues since, I would say, only part of the kernel code is compiled and executed.

A kernel-related recompilation is also required if you want to take advantage of some features that are only available as patches (and not documented in the standard kernel release).
No wonderIt’s great that Debian handles the kernel as a superior package that traditional kernels don’t come and compile. Since the actual kernel is still under the control of the appropriate packaging system, it can then be deployed to multiple computers without any problems or removed. Moreover, the scripts associated with the packages improve the interaction with the bootloader and, of course, with the initrd generator.
the original versions of Linux all contain what is needed to build the Debian package bundled with the kernel. But you should still install the build-essential installer to make sure you have the necessary tools to build the Debian package. In addition, the configuration kernel step requires the Libncurses5-dev package. Finally, all fakeroot packages allow you to create any Debian packages without admin rights.
8.10.1.Introduction And Prerequisites
Like everything useful on a Debian machine, the available Linux kernel sources come in a package. To get them, just install the linux-source-version package. The Through apt look ^linux-source command lists the differentnew versions of the kernel created by Debian. The latest version is available in an unstable distribution: you can restore it without much risk if (especially your own APT is set up according to HOA guidelines 6.2.6, Multiple “working with distributions”). Note that the source code included in most of these packages does not exactly match what appears to be published by Linus Torvalds and the developers in the currently released kernel; Like all distributions, Debian applies a number of patches that may (or may not) end up in the exact original version of Linux. These changes ensure that fixes/features/drivers are carried over from newer kernels, versions of interesting features that have not yet been (fully) merged into the Linux tree, and sometimes even Debian-specific changes.
The rest of this section is about version 4.19 of the Linux kernel, but the examples can of course be adapted to the specific version of the desired kernel.
We have the entire linux-source-4.19 package installed. This is /usr/src/linux-source-4.19.tar.xz, a compressed archive of your current kernel sources. you needo Extract these files to a new directory (not just around /usr/src/, since no special permissions are needed to compile the Linux kernel): ~/kernel/< Code > became / appropriate.cd mkdir
$~/kernel; tar ~/kernel$ -xaf /usr/src/linux-source-4.19.tar.xz
8.10.2. Next Get All Sources
The step is to customize the kernel to suit your needs. What exactly you do depends on your goals.
When recompiling the most recent kernel version (perhaps with an additional patch), the configuration should remain as close as possible to the one proposed by Debian. In this case, instead of configuring a lot from scratch, just notify the /boot/config-version file (the version is the one currently most used by the kernel, found with uname -r command) fix the a.config file on the submitting sites, which contains the kernel sources.
$ cp /boot/config-4.19.0-5-amd64 ~/kernel/linux-source-4.19/.config
If you do not need to change any of your personal settings, you can stop here and skip to section 8.10.Please compile the package". For example, if you need to change it to solve it or help set everything up from scratch, you need to use it to tune your kernel. There are various dedicated interfaces in the kernel localization directory that can be used by chanting the make target command, where indeed target is one of the values described below.
make menuconfig and compiles to run a text-based user interface (this obviously requires the libncurses5-dev package) that allows you to navigate through the available hierarchical structure. Pressing the space Important changes the value of the selected procedure, and the Enter key confirms the button selected by scrolling the bottom of the Tour; the selection screen opens the selected submenu; Exit closes each of our current screens and moves up the Help Here hierarchy; displays more detailed information about the role of the option being used. You can use the arrow keys to move through the list of options and buttons. To exit, select the program, Exit Setup in the main menu, after which the program will save the changes made; you get used to it,you when satisfied with your own decisions.
