WSL Overlay (Running Gentoo on Windows Kernel)

gentoo-wsl's Introduction

You can use Gentoo on Windows Kernel

Installation

install/enable WSL on Windows (Using Programs and Features)
download stage3 https://www.gentoo.org/downloads/
use https://github.com/RoliSoft/WSL-Distribution-Switcher and target stage3 tarball (for example run following from console C:\Python3\Python install.py stage3-amd64-20170413.tar.bz2)
set root as default login by running lxrun /setdefaultuser root from windows powershell
after login export TERM=xterm and add it to .bashrc
switch to no-multilib profile eselect profile set default/linux/amd64/13.0/no-multilib
put sys-apps/portage -ipc into /etc/portage/profile/package.use.force it doesn't work well with ipc

Resolved

bug with nlink on perl: microsoft/WSL#186

Suggestions

Add an exception for windows antivirus or disable them during emerge processes

gentoo-wsl's Issues

Fixing emerge glibc

sys-libs/glibc won't compile without mounting /dev/pts with gid=5

The easiest solution I found is to emerge it with USE="suid", then the emerge pre-check process doesn't look for this to be mounted.

Fixing bad `ld` symlink

Just thought I'd leave some notes on my experiences following your instructions here:

I had problems with the symlink for ld, which prevented me from merging anything that required compiling. in /usr/x86_64-pc-linux-gnu/binutils-bin/2.25.1/ I found:

lrwxr-xr-x 1 root root 52 Jan 19 03:59 ld -> ./usr/x86_64-pc-linux-gnu/binutils-bin/2.25.1/ld.bfd

which was clearly bogus but nearly correct. I replaced it with

lrwxrwxrwx 1 root root 6 Jan 27 01:26 ld -> ld.bfd

which seems to have restored functionality.

The Portage patch PR50 also seems to no longer be required, I think it's been included now.
Also, I believe you should be able to use the no-multilib stage3 from the start if you want. It has the same ld issue.

Fixing login as root

If you just installed Gentoo on WSL you probably can't login as root by executing 'su' as your password will always fail.
An easy trick is to run 'lxrun /setdefaultuser root' on your cmd or powershell before opening your gentoo bash. After, you should delete the user you created on ubuntu on WSL and create it again using your gentoo bash in order to be able to login as the regular user. Then 'su' will run successfully accepting your password.

glibc-2.25-r9 for WSL

Attached file is a archive of glibc-2.25-r9 ebuild for WSL.
glibc-2.25-r9_ebuild.zip

Gentoo's glibc is glibc-2.25-r9 now but it had facilities that WSL does not support yet.
You might use glibc-2.23-r4 with masking new glibc but version 2.23 have another problems;

it could not be built by new binutils-2.29.1-r1 without another glibc patch, so you should mask new binutils too
compiling some guile modules makes BSOD on glibc-2.23-r4 -- I found this while comiling gnutls but guile itself, guile-2.0.14-r3 on gentoo or guile-2.0.11-r1 on funtoo, also makes BSOD.

So, it could be better to upgrade glibc with "Revert linux spawni.c simplify error reporting" patch.

Fixing "syntax error near unexpected token `newline'"

If while opening your bash you get an error message like "syntax error near unexpected token `newline'", this is because now your gentoo bash reads the .bashrc file originally from ubuntu. Check the line that is complaining by editing or commenting it, or create a new gentoo-based .bashrc file and you won't see the message anymore. Below I copy-pasted a working .bashrc file for gentoo.

# /etc/bash/bashrc
#
# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output.  So make sure this doesn't display
# anything or bad things will happen !


# Test for an interactive shell.  There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.
if [[ $- != *i* ]] ; then
        # Shell is non-interactive.  Be done now!
        return

Tips for emacs

USE flags for emacs

Emacs works well unless using gtk3 and dbus. I have no idea why gtk3 making problem but it is.
So, it's my woking USE flags;

SUNJOONG-DESKTOP ~ # emerge -pv emacs
[ebuild   R    ] app-editors/emacs-24.5-r3:24::gentoo  USE="X gfile gtk inotify libxml2 png ssl svg toolkit-scroll-bars xft xpm zlib -Xaw3d -acl -alsa (-aqua) -athena -dbus -games -gconf -gif -gpm -gsettings -gtk3 -gzip-el -hesiod -imagemagick -jpeg -kerberos -livecd -m17n-lib -motif -pax_kernel (-selinux) -sound -source -tiff -wide-int" 0 KiB

bash.exe shortcut

There is a shortcut of bash.exe named "Bash on Ubuntu on Windows" in your Start Menu like
"C:\Users\sunjoong\AppData\Roaming\Microsoft\Windows\Start Menu\Programs" directory.
You know, sunjoong is my user name, so do with your username in your case.
Change the shortcut name to "Bash on Gentoo on Windows" for looking good.

~~The target attribute of that shortcut is~~
~~C:\Windows\System32\bash.exe ~~~

~~Append "-l" option like this;~~
~~C:\Windows\System32\bash.exe ~ -l~~

~~Then, ~/.bash_profile file will work.~~

UPDATE: I heard bash.exe will launch bash login shell starting 16184, microsoft/WSL#2067 (comment) ; so you might not need to append -l option after then.

~/.bash_profile

~~This is my ~/.bash_profile;~~
~~SUNJOONG-DESKTOP ~ # cat ~/.bash_profile~~
~~# This file is sourced by bash for login shells. The following line~~
~~# runs your .bashrc and is recommended by the bash info pages.~~
~~if [[ -f ~/.bashrc ]] ; then~~
~~. ~/.bashrc~~
fi

~~/mnt/c/Windows/System32/tasklist.exe /fi 'imagename eq vcxsrv.exe' ~~
~~2> /dev/null ~~
~~| grep 'No tasks are running' > /dev/null~~
~~if [ $? -eq 0 ]; then~~
~~/mnt/c/Program\ Files/VcXsrv/vcxsrv.exe ~~
~~:0 -multiwindow -clipboard -wgl &> /dev/null &disown~~
fi
~~export DISPLAY=:0~~
~~SUNJOONG-DESKTOP ~ #~~

~~I had installed VcXsrv Windows X Server.~~
~~My ~/.bash_profile check whether X server be running and run X server if not running.~~

runemacs.exe

~~I'm using a modified runnig emacs wrapper. This is a source - runemacsWSL.zip.~~
~~This is a compiled binary - runemacs.zip. It acts like "bash.exe -l -c emacs".~~
~~So, I can run emacs by mouse double-clicking with this wrapper and ~/.bash_profile.~~

Microsoft Edge as emacs browse-url-browser-function

This is a part of my emacs init file;

(defun browse-url-edge (url &optional new-window)
  (shell-command
   (concat "/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe "
           "start microsoft-edge:'\\\"" url "\\\"'")))

(custom-set-variables
 '(browse-url-browser-function 'browse-url-edge)
 '(inhibit-startup-screen t))

(setq default-directory "/mnt/c/Users/sunjoong/Desktop")

You could notice browse-url-edge function and browse-url-browser-function .
That makes set external web brower to Microsoft Edge.
The inhibit-startup-screen and default-directory make emacs looking other windows program.
You know, sunjoong is my user name, so do with your username in your case.

More simple method to aviod ipc lock error

Before I found your installation howto, I managed to install gentoo.
Just for an information...

Install Ubuntu
In Windows PowerShell;

PS C:\Users\sunjoong> lxrun /install /y
PS C:\Users\sunjoong>

Extract Gentoo stage3 tarball
Run Bash on Ubuntu on Windows.

root@SUNJOONG-DESKTOP:~# mkdir --mode=755 /rootfs
root@SUNJOONG-DESKTOP:~# cd /rootfs
root@SUNJOONG-DESKTOP:/rootfs# wget http://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3-amd64/stage3-amd64-20170413.tar.bz2
root@SUNJOONG-DESKTOP:/rootfs# tar xvjpf stage3-amd64-20170413.tar.bz2
root@SUNJOONG-DESKTOP:/rootfs# echo 'USE_EXPAND_HIDDEN="ABI_X86"' >> /rootfs/etc/portage/make.conf
root@SUNJOONG-DESKTOP:/rootfs# echo 'MULTILIB_ABIS="amd64"' >> /rootfs/etc/portage/make.conf
root@SUNJOONG-DESKTOP:/rootfs# echo 'FEATURES="-parallel-fetch"' >> /rootfs/etc/portage/make.conf
root@SUNJOONG-DESKTOP:/rootfs# echo 'sys-libs/glibc suid' > /rootfs/etc/portage/package.use/glibc
root@SUNJOONG-DESKTOP:/rootfs# rm ~/.bashrc ~/.profile
root@SUNJOONG-DESKTOP:/rootfs# cp -a /rootfs/etc/skel/.bash* ~
root@SUNJOONG-DESKTOP:/rootfs# rm stage3-amd64-20170406.tar.bz2
root@SUNJOONG-DESKTOP:/rootfs# exit

Replace rootfs to Gentoo
In Windows PowerShell;

PS C:\Users\sunjoong> cd ${env:LOCALAPPDATA}/lxss
PS C:\Users\sunjoong\AppData\Local\lxss> move rootfs rootfs.old
PS C:\Users\sunjoong\AppData\Local\lxss> move rootfs.old\rootfs rootfs
PS C:\Users\sunjoong\AppData\Local\lxss> del -recurse rootfs.old
PS C:\Users\sunjoong\AppData\Local\lxss>

Update Gentoo
Now, you got Gentoo.
Run Bash on Ubuntu on Windows but the linux system is Gentoo.

SUNJOONG-DESKTOP ~ # emerge --sync
SUNJOONG-DESKTOP ~ # emerge -uND @world
SUNJOONG-DESKTOP ~ #

Add default user

SUNJOONG-DESKTOP ~ # emerge sudo
SUNJOONG-DESKTOP ~ # groupadd -g 1000 sunjoong
SUNJOONG-DESKTOP ~ # useradd -u 1000 -g 1000 sunjoong
SUNJOONG-DESKTOP ~ # passwd sunjoong
SUNJOONG-DESKTOP ~ # echo 'sunjoong ALL=(ALL) ALL' >> /etc/sudoers
SUNJOONG-DESKTOP ~ # exit

And in Windows PowerShell;

PS C:\Users\sunjoong\AppData\Local\lxss> lxrun /setdefaultuser sunjoong
PS C:\Users\sunjoong\AppData\Local\lxss> exit

You know, sunjoong is my username so you may change it,
and stage3 tarball filename was that of 2017-04-13.

Your howto said to edit AbstractEbuildProcess.py file,
but that matches 'FEATURES="-parallel-fetch"' of mine.
