GtkD undefined reference

Question

My code:

import gtk.MainWindow;
import gtk.Main;

void main(string[] args)
{
    Main.init(args);
    auto win=new MainWindow("Hello World");
    win.setDefaultSize(200,100);
    win.showAll();
    Main.run();
}

When I try to compile with DMD (or gdc), I get the errors:

dmd ./test.d -L-L/usr/local/include/d/gtkd-2/lib
test.o:(.data+0x10): undefined reference to `_D3gtk10MainWindow12__ModuleInfoZ'

I have spent the last two days trying to compile this simple hello world app and have looked at multiple websites, including this one. I have tried the linking tricks that others have proposed but without success. I have GtkD and gtk+ both installed (I have used gtk with C, so I know that part is working correctly) It does not seem to matter if I use dmd or gdc (currently using dmd as I found more online solutions for that compiler).

I should also say that regular, non-gui D code compiles fine. It is when I attempt to use GtkD that this occurs.

I found the answer. It is:

gdc ./test.d -Wall pkg-config --cflags --libs gtkd-2 -I/usr/include/d/gtkd-2 -L/usr/local/lib -lpq
