Ok, so what you basically do is go to Microsoft Store which is in a start menu under the letter M obviously.

You probably already have an account if you got Windows installed, but if not, it will ask you to register, it's simple - just provide any email and password.

There just type Ubuntu in search bar and install Ubuntu app in one (or maybe two) click(s)

What will happen is you will have compact distribution of Ubuntu installed in Windows, it's a standard feature there nowadays. There's also Debian and it already has Gambas in repo, but it doesn't work, qt5 dependency is broken.

Now, when Ubuntu is installed, you will have Ubuntu app icon in Start menu, wich is basically a bash shell chrooted to Programm Files directory where your Ubuntu infrastructure is installed. When it would be first run it'll ask you to enable Windows Subsystem For Linux (WSL) and tell you exactly how to do it, also one click more or less.

Everything else is just installing Gambas (or anything else) in Ubuntu, so you add a PPA, then "apt-get update" then "apt install gambas3" and you are ready to go, console Gambas apps will now work if you run them from this bash console or by typing "wls <programm>.gambas" in windows cmd or anywhere else in Windows, even from .bat or .cmd file, or another program capable of "shell" operator.

Gambas in Ubuntu (at lease in Windows' repository) seems to be linked to QT4, and GTK3 is also there by default, so you can create and run those types of apps. And, as I've already said, you can run cli apps without any additional moves.

To run any graphical Linux program in Windows 10 you need an X server. Just google, download and install Xming, it's free and easy to install. There's also an X server in Microsoft Store but it's 50 bucks so no thanks.

When XMing is installed what I do is run a configurator that creates an Xlaunch file. So I tell it to not create a root window, just to be ready to serve apps without authentication, and then i put this xlauch file in Autorun in Start menu

So now you can either specify DISPLAY=:0 in bash cli and run any program from now on, or just create a basic windows shortcut with a line that I already provided before.

For example I have a app icon for Gambas on my desktop. The command it executes on double click is:

C:\Windows\System32\wsl.exe DISPLAY=:0 LANG=ru_RU.UTF-8 gambas3

it sets DISPLAY environment to work with Xmin and it sets my native locale, so I can see Gambas IDE in my native language.

That's it. Any software then written in gambas is run from such shortcuts with the same scheme: C:\Windows\System32\wsl.exe DISPLAY=:0 LANG=ru_RU.UTF-8 myprogramm.gambas

BTW the very same way you can ran, say, Firefox, or Chrome, or any other Linux version of graphical software that you install with apt in your pseudo Ubuntu. It works in Windows 10 just like that.

RedHat's Cygwin did this for years, but now Windows 10 just officially supports Linux binaries through WSL, so no need for any additional software. If you want to, say, run Apache or any other Linux non-graphical software - you don't even need Xming? just install Ubuntu, apt install your app and you are good to go. Even sshd works, but you have to remember that Windows 10 also has it's own SSH, so you have to disable it first.

Oh, and keep in mind that you can't mount anything and /dev is just empty, but your Windows drives are already in /mnt, so you still see all your Windows infrastructure and you can run Windows software from inside of this Linux chroot if you will

Did you manage to create a shortcut to start Gambas directly from Win Desktop with VcXsrv, as described in your post with Xming?

I wonder what this means for gambas applications?
