Meaning of GLib-GIO-CRITICAL assertion error

glib, runtime-error, ubuntu

Solution

I had the same problem as I have just started on the same tutorial. Replace:

    Gtk::ApplicationWindow window;

with

    GTK::Window window;

If you read the description of the code in the tutorial the latter is actually the code that is discussed. Making this change made the program work for me.

Problem

I successfully compiled the following program simple.cc: ``` #include <gtkmm.h> int main (int argc, char *argv[]) { Glib::RefPtr<Gtk::Application> app = Gtk::Application::create(argc, argv, "org.gtkmm.examples.base"); Gtk::ApplicationWindow window; return app->run(window); } ``` using the following command: ``` g++ simple.cc -o simple `pkg-config gtkmm-3.0 --cflags --libs` ``` Which gave me the executable simple, but when I tried to run it, I got the following error: ``` (simple:2964): GLib-GIO-CRITICAL **: g_application_list_actions: assertion `application->priv->is_registered' failed Segmentation fault (core dumped) ``` As far as I can tell, I have the latest and greatest GLib packages. I'm running Ubuntu 12.04 LTS.
