(process:5746): GLib-GObject-CRITICAL **: gtype.c:2708: You forgot to call g_type_init() - Fedora 16

[Phong Cao <phngcv gmail com>]

Hello everybody,

I am trying to develop a small music manager using GStreamermm & Gtkmm called Dingo. It uses Gst::Discoverer to read media files' metadata & inserts them into Gtk::TreeView and also saves those metadata information in an SQLite3 database. The program was compiled. However, when I ran it, I got these errors:

[phongcao@dhcp-vlan16-114 dingo]$ ./main

(process:6115): GLib-GObject-CRITICAL **: gtype.c:2708: You forgot to call g_type_init()

(process:6115): GLib-GObject-CRITICAL **: gtype.c:2708: You forgot to call g_type_init()

(process:6115): GLib-GObject-CRITICAL **: g_type_interface_add_prerequisite: assertion `G_TYPE_IS_INTERFACE (interface_type)' failed

(process:6115): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed

(process:6115): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed

This is the backtrace in GDB. I am using Fedora 16 x86_64 with gtkmm-3.0:

I am not sure what is going on with my program. I already called Gtk::Main kit(argc, argv) & Gst::init(argc, argv) in my "main" function. Please notice that all the files are compiled but this problem was produced at run-time. I have been stuck with this problem for several days.

Attached with this email is the source code of this program. I hope you guys can download & compile it in your computer to see if it works. Just type "make" and everything will be compiled... I wonder if there are even errors in my Makefile.

Thank you for reading my message! Have a good week!
