Hello, I'm running Ubuntu 19.04,
I would like to see a working gtkD example on my system finally.

However it seems it is not that simple as just:

• sudo snap install --classic dmd
• apt-get install libgtkd-3-dev
• And running some examples from
  http://www.dsource.org/projects/gtkd/wiki/CodeExamples
• rdmd hello.d

What I'm missing and how should I setup for the examples to run correctly?

Right now I'm getting

vaidas@vaidas-SATELLITE-L855:~$ rdmd hello.d 
hello.d(1): Error: module `MainWindow` is in file 'gtk/MainWindow.d' which cannot be read
import path[0] = .
