Testing Legato based Apps on localhost

Hello all,

I want to test a simple helloworld app on localhost without touching the real mangOH yellow Hardware,

local host is my laptop with WSL and Ubuntu 20.04, I am using legato as a plug in to VS Code

Can anyone help me.
I am following attached post but getting this issue

abharati@fsdclient0598:~/myWorkspace$ make localhost
make: *** No rule to make target ‘localhost’. Stop.
abharati@fsdclient0598:~/myWorkspace$

also mkapp and mksys does not work for me, why

Suggest you testing the application directly in mangoh board

Not sure if there is still maintenance on the localhost target

so is it not possible to run the legato framework apps on laptop ?
also is it not possible to create a legato app binary file for my local laptop by any other method?

Note - I dont want to change the legato specifc libarries and dependencies just to cross compile the app for my laptop.

I have no experience in using localhost, you can see whether there is relevant thread in this forum or mangoh forum
