<p>
I just extracted the tar file into ~/opt and ran pcb-rnd fine under WSL.
However this is on a WSL with *known working* X11, and it took me a bit
of work some time ago to get that X11 support working correctly...
<p>
The problem I was having at the time was that /tmp/.X11-unix wasn't being
linked to /mnt/wslg/.X11-unix as it should be. Instead it was using a
normal Linux-esque internal .X11-unix which of course doesn't work. 
<p>
What I had to do was:
<p>
1. Make sure that /etc/wsl.conf has:
<pre>
[boot]
systemd=true
</pre>
<p>
2. Create the file (or check it if it's there) /etc/tmpfiles.d/wslg.conf -
<a href="https://github.com/microsoft/WSL/issues/6999#issuecomment-2303010704">
which should have:</a>
<pre>
L+ /tmp/.X11-unix - - - - /mnt/wslg/.X11-unix
</pre>
<p>
Also, ensure that your installation is using WSL version 2 and not
version 1, or you'll be banging your head against a wall...
