MSYS2 в Windows 10 с Glade (сбой gtk_entry_get_text: утверждение 'GTK_IS_ENTRY (entry)')

К сожалению, я новичок в программировании на C, и у меня много проблем с совместимостью внешних библиотек между Linux и Windows.

Я пытаюсь научиться использовать GTK 3, использовать Glade для созданияинтерфейс и geany, чтобы написать код в GCC

Я ищу решение в Интернете в течение 4 дней, но я не понимаю, как его решить: ниже приведена ошибка, которая появляется, когда "Нажата кнопка «ОК».

Пожалуйста, наберитесь терпения, я не знаю, кого сейчас спросить. Спасибо за вашу помощь. 

(test:1644): Gtk-CRITICAL **: 11:47:31.588: gtk_entry_get_text: assertion 'GTK_IS_ENTRY (entry)' failed

Код, написанный в GCC через Geany 

#include <stdio.h>
#include <gtk/gtk.h>
#include <gmodule.h>

int main(int argc, char *argv[])
{
    GtkBuilder      *builder; 
    GtkWidget       *window;


    gtk_init(&argc, &argv);

    builder = gtk_builder_new();
    gtk_builder_add_from_file (builder, "test.glade", NULL);

    window = GTK_WIDGET(gtk_builder_get_object(builder, "TestWin"));



    gtk_builder_connect_signals(builder, NULL);

    g_object_unref(builder);

    gtk_widget_show(window);                
    gtk_main();

    return 0;
}


// I have to put (extern "C" G_MODULE_EXPORT ) because without  give Could not find signal handler 'on_ok_button_clicked'.  Did you compile with -rdynamic?

extern "C" G_MODULE_EXPORT void on_ok_button_clicked(GtkButton *msgbox_ok, GtkEntry *origin, GtkEntry *target, gpointer user_data)
{



        const gchar *OriginText;
        const gchar *TargetText;

        OriginText = gtk_entry_get_text (GTK_ENTRY (origin)); // gtk_entry_get_text: assertion 'GTK_IS_ENTRY (entry)' failed

        TargetText = OriginText;

        void gtk_entry_set_text (GtkEntry *target, const gchar *TargetText); //Give no action like no command exist




}
extern "C" G_MODULE_EXPORT void on_cancel_button_clicked(GtkButton *cancel_button, gpointer user_data)
{
    gtk_main_quit();
}
extern "C" G_MODULE_EXPORT void on_TestWin_destroy(GtkWidget *TestWin, gpointer user_data)
{

        gtk_main_quit();
}
