I wonder if the implementation of the libraries or settings package is not well defined.
I used:
sudo dnf groupinstall "Development Tools" "Development Libraries"
I got this error after watching a video tutorial about Vala and GTK+ on ubuntu where this error does not appear.
This is error:
[catafest@localhost ~]$ valac test.vala --pkg gtk+-3.0
[catafest@localhost ~]$ ./test
(test:11980): GLib-GObject-CRITICAL **: 15:53:25.638: g_value_set_boxed: assertion 'G_VALUE_HOLDS_BOXED (value)' failed
[catafest@localhost ~]$
I used this source code:
GNU nano 6.4 test.vala
using Gtk;
namespace Test {
int main(string[] args) {
Gtk.init(ref args);
// #define G_VALUE_HOLDS_BOXED 1;
//Value g_value_set_boxed = Value (0);
var window = new Gtk.Window();
//window.title = "This is a Vala test";
window.set_title("This is a new title");
window.border_width = 10;
window.window_position = Gtk.WindowPosition.CENTER;
window.set_default_size(350,80);
window.destroy.connect(Gtk.main_quit);
window.show_all();
Gtk.main();
return 0;
}
}
