    Required guidance on building a kernel module like v4l2loopback on WSL2 and how to access...


    I have the source code of v4l2loopback kernel module that works in Ubuntu 20 in a laptop. Now I am trying to compile the same code in Ubuntu 20 but inside WSL2. For that I am using this:make -C /lib/modules/$shell uname -r/build M=$PWD modulesThe problem is that /lib/module/ is empty. So I tried getting the headers using:sudo apt search linux-headers-`uname -r`Sorting... DoneFull Text Search... DoneBut nothing get's populated in the modules folderIs there anything I need to do in order that folder contains all required modules?

    :)

    WSL2 for windows

    I have failed into installing WSL for Windows. I have read here: https://docs.microsoft.com/en-us/win.../install-win10 how to do it, and at step 4:


    1. Download the latest package:
      [COLOR=var(--text)][COLOR=var(--info-dark)] Note[/COLOR]
      If you're using an ARM64 machine, please download the ARM64 package instead. If you're not sure what kind of machine you have, open Command Prompt or PowerShell and enter: systeminfo | find "System Type".
      [/COLOR]
    2. Run the update package downloaded in the previous step. (Double-click to run - you will be prompted for elevated permissions, select ‘yes’ to approve this installation.)

    I encountered:
