Building a Linux kernel for WSL2 using GCC
by Simon Eigeldinger 02 Nov '20

02 Nov '20

Hi, Moved away from Clang to GCC. Sounds more standard anyway. *smile* Now you can use all Ubuntu versions to compile the kernel. Building a Linux kernel for WSL2 using GCC Last updated: 18:28 02.11.2020 Or just get it and updated versions of this documentation from here: https://www.dropbox.com/sh/nhcbxnv5zllxuof/AABbHdkf3Yd4RuEPnkBf5MMLa?dl=0 Note: Changed from Clang back to GCC because this seems to be a more standard way of doing it. Sources https://www.xyb.name/2020/03/14/build-your-kernel-for-wsl2/ https://nathanchance.dev/posts/wsl2-kernel-clang/ Howto 1. Download and install the needed tools. Use Ubuntu. $ sudo apt update $ sudo apt upgrade $ sudo apt install g++ make flex bison libssl-dev libelf-dev bc wget 2. Download the kernel source code The latest is 5.9.3 at the moment of writing. Find the latest info on https://www.kernel.org/ $ wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.9.3.tar.xz $ tar xf linux-5.9.3.tar.xz $ cd linux-5.9.3 $ wget https://raw.githubusercontent.com/microsoft/WSL2-Linux-Kernel/master/Micros… You can also use linux-next (bleeding edge code) if you want: $ wget https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/snapsho… for the kernel of 30 October 2020. Modify the dates. See the kernel website for the latest. 3. Build the kernel. An out directory (out.x86_64) can be handy to have a clean environment. $ make -j$(nproc) -s KCONFIG_CONFIG=config-wsl O=out.x86_64 distclean olddefconfig all Move the kernel to the Windows file system. I have my kernels sitting at e:\wsl\kernel. $ cp out.x86_64/arch/x86/boot/bzImage /mnt/e/wsl/kernel/linux-5.9.3 Tell WSL2 to use that kernel when booting up. Create a .wslconfig file in your user directory for example at c:\users\username. This file should contain the following: [wsl2] kernel = e:\\wsl\\kernel\\linux-5.9.3 Note that you need to use double backslashes. Then do on a cmd window. $ wsl --shutdown Then load a linux distro and type $ cat /proc/version Now you should see something like that Linux version 5.9.3-microsoft-standard (root@SimonPC) (gcc (Ubuntu 10.2.0-13ubuntu1) 10.2.0, GNU ld (GNU Binutils for Ubuntu) 2.35.1) #1 SMP Mon Nov 2 17:42:10 CET 2020 Some have noticed that the VM gets stuck starting with a custom kernel at times; if that happens, run wsl --shutdown and try reopening one of the distributions again, it will usually work after a couple of times. Enjoy.

hyper v
by Marvin Hunkin 02 Nov '20

02 Nov '20

Hi. Got the jaws 2020 august remote remote services and a trial. Now downloaded and installed. Now when I go to hyper v. and connect, with windows server 2019. Does not give me any speech, just says input capture and then caps lock on or off, and it chrashes my system. So did have a trial of a remote server from http://www.heropa.com, but cost them a lot of cash and burnt my bridges. So wondering if there a free remote computer server service, that's free, has windows server 2016 or 2019, then can then install nvda, and jaws on it. Wondering. If nvda has a remote option. Is that fee or cost money or a trial. Thanks.

Hi. Okay will go and research that. And do have jaws running, unless need the remote jaws and then either need to get a trial licence or need to then purchase. With nvda, does this process work. When I launched nvda, it was able to read the configuration dialog and the preferences. But jaws did not. Okay will see if there's an article how to forward all keystrokes to hyper vi via nvda key strokes. Thanks. Ps: my friend install virtual box, but kept crashing and powering off. My 30 day vm ware workstation trial ended, and did not want to use crack keys. And when I did research, the vm ware key is stored on the copy or a hidden folder in windows. Thanks.shadow

Hi. A sighted friend is mentoring me for my network course from http://www.upskilled.edu.au. Got windows 10, windows server 2019 and hyper v. is there a way for screen readers to read the content. Jaws , nvda , windows narrator just says input capture. Would window-eyes read this content any better. Thanks.

Evening all, Just wondering if anyone here has experience of SCCM labs. I’m doing the administrateing and configuring SCCM course this week and I’m working through the labs with colleagues.

I’ve seen the Microsoft demo labs, are they any good? grateful for any tips/advice. Thanks, Kieran. Get Outlook for iOS<https://aka.ms/o0ukef> Save Time Do It Online!

Hi All, Do any of you know of a Windows based tool that I can use to add files to a Windows Server ISO image? I know I could do this by having a USB but I need to do this with ISO in a virtual environment. Thanks, Billy
