gtk+-3.10.4 bundle and gtk+3.6 or what bundle for application 1 -10

[songqing shan <shans123 hotmail com>]

Hi,


I would like to have anyone to help me.


I use MinGW+msys and gtk+-3.10.4 bundle to compile examples on the 
https://developer.gnome.org/gtk3/stable/gtk-getting-started.html.<https://developer.gnome.org/gtk3/stable/gtk-getting-started.html>
 The examples in Sections (Basics, Packing, and Building interfaces) are fine. However, following the 
instruction, I compile application 1-10, but no any application works. All errors are similar. I give 
application 1 error as follows.

../src/main.c:8:29: note: in expansion of macro 'G_APPLICATION'
   return g_application_run (G_APPLICATION (example_app_new ()), argc, argv);

I also used gtk+3.6 bundle to compile these ten examples before. The same errors occurred.  I used the codes 
both I downloaded and I input. The same errors occur.

In order to resolve above issues, I wrote my own class. I can make it, but run time error occurs


(editor.exe:2212): GLib-GObject-WARNING **: specified class size for type 'Examp
leApp' is smaller than the parent type's 'GtkApplication' class size

(editor.exe:2212): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0'
failed

(editor.exe:2212): GLib-GObject-CRITICAL **: g_object_new: assertion 'G_TYPE_IS_
OBJECT (object_type)' failed.

In addition, I used MinGW+msys and gtk+-3.6 bundle to compile another example from anther website and the 
example works fine. However, after my computer was scammed, I reinstalled MinGW+msys and gtk+-3.10.4 bundle 
and compile the same example. following warnings occur,

../src/editor.c: In function 'parameterizer_app_class_init':
../src/editor.c:652:39: warning: assignment from incompatible pointer type [-Wincompatible-pointer-types]
  G_APPLICATION_CLASS(class)->activate = parameterizer_app_activate;
                                       ^
../src/editor.c:653:35: warning: assignment from incompatible pointer type [-Wincompatible-pointer-types]
  G_APPLICATION_CLASS(class)->open = parameterizer_app_open;
                                   ^
code:

static void parameterizer_app_class_init(ParameterizerAppClass *class)

{

G_OBJECT_CLASS(class)->finalize = parameterizer_app_finalize;

G_APPLICATION_CLASS(class)->activate = parameterizer_app_activate;

G_APPLICATION_CLASS(class)->open = parameterizer_app_open;

}



If anyone can help me with these questions, I really appreciate.


Thank you in advance,


Song
