digitalmars.D - Want to start a graphical Hello world.

Hi there ,  i have this code :
________________________________________________

import gtk.MainWindow, gtk.Label, gtk.Main;

class GoodbyeWorld : MainWindow {
     this() {
         super("GtkD");
         add(new Label("Goodbye World"));
         showAll();
     }
}

void main(string[] args) {
     Main.init(args);
     new GoodbyeWorld();
     Main.run();
}

________________________________________________

For this i have made a folder named GIT in the linux directory 
/usr/local/GIT
And Gitcloned in the GIT folder :
git clone https://github.com/nomad-software/x11
git clone https://github.com/nomad-software/tcltk.git
The clones are now in /usr/local/GIT/

When i start the upper code in a cmd the result is as follows :
___________________________________________________________________
$ dmd hw_graphical.d
hw_graphical.d(1): Error: module MainWindow is in file 
'gtk/MainWindow.d' which cannot be read
import path[0] = /usr/include/dmd/phobos
import path[1] = /usr/include/dmd/druntime/import


What must be done that the code make a graphical window ?

I want to make the D programming tkd module ready for GUI 
programming.
Need a step by step advice for BEGINNERS in D programming.

Any Internetlink for step by step instructions how to arrange D 
and TK would be helpful !

You need to link in and tell the compiler where to find the 
library. Tru

dmd -I/usr/local/GIT/whatever hw_graphical.d -L-lgtk

and whatever else the library does. I haven't used gtkd so I 
don't know the exact thing for it, but something like that.

Hmm, but you are using GtkD in your example... It looks like you 
compiled the wrong code.
What you actually want is GtkD from 
https://github.com/gtkd-developers/GtkD or installed from the 
Debian repositories (in case you want to use LDC) via `sudo apt 
install libgtkd-3-dev`

If you want to use GtkD and achieve a quick result, you might 
want to use the Dub package manager.
GtkD also has a few demo applications that show you how to use it 
with dub, take a look at
https://github.com/gtkd-developers/GtkD/tree/master/demos/gtk

tkd is a project different from GtkD (which your example above is 
using). For "modern" UI that integrates well with GNOME, you will 
highly likely want to use GtkD. Tcl/Tk is of course an option as 
well, but the D bindings look less complete and well maintained.
In case you want to use Tk, you will need to change your code to 
actually use it, instead of GTK+ though ;-)

I can't help with Tk, but for GTK+ a quick Google search found 
https://sites.google.com/site/gtkdtutorial/ - this tutorial is 
rather old, but it might be useful as a reference.

This experience report by Gerald Nunn might also be an 
interesting read for you:
