Hello everybody!
I'm a newbie to vala language, I faced to a strange problem recently and
couldn't find any help in vala documentations.
In my app, I have declared a class named "Global" in a file "global.vala":
using GLib;
public class MyApp.Global : GLib.Object {
public static string dataDir = "/usr/local/share/";
}
And I have a "main.vala" file, whith this code inside:
using GLib;
using Gtk;
public class MyApp.MainWindow : Window {
static int main (string[] args) {
stdout.printf ("all data is in: " + Global.dataDir);
return 0;
}
}
Hi,
I'm really sorry, I can't help you.
But since I'm doing something similar in a software I'm writing, I'll take
the occasion and ask a little piece of advice on the list.
You are hard-coding dataDir into your application; assuming you're using
the GNU autotools, the data directory can be configured using the --prefix
option of configure. If that value is changed, the hard-coded dataDir will
not point to the right directory.
What I've done to work around the issue is to create a small utility class,
where I replace the value of prefix at build time:
public class AutotoolsSupport : GLib.Object {
public static const string DATA_DIR = "@prefix@/share/";
}
The above snippet goes in autotoolssupport.vala.in, so that a suitable
autotoolssupport.vala is generated when AC_SUBS(prefix) is called in
configure.ac.
I would like to have a cleaner way to refer to @datadir@ from inside a Vala
source file. Any suggestion?

Resistance is futile, you will be garbage collected.
