[Vala] Define constant at compile time

[Andrea Corbellini <corbellini andrea gmail com>]

Hi all,

I'm new to Vala and I'd like to have some help to solve a small but
frustrating problem. Basically, I have a Gtk.UIManager that I want to
initialize in this way:

  var ui_manager = new Gtk.UIManager();
  ui_manager.add_ui_from_file(UI_FILE);

I want to specify the constant UI_FILE at compile time, but I don't know
how to do that. In C I would write something like that:

  #ifndef UI_FILE
  #define UI_FILE "default-path.xml"
  #endif

and then I would call gcc with the option -DUI_FILE="something". I've
tried to use the -D option of the Vala compiler, but it doesn't seem to
work as I expect. Any ideas?

Many thanks,
Andrea
