Undeclared GTK_OBJECT during g++ compilation - g++

Question

I get errors during compilation of a GTK+ application saying I have undeclared functions/definitions (I believe GTK_OBJECT might be a definition in a header file). This is my code (main.c):
#include <gtk/gtk.h>
static gint delete_event_cb(GtkWidget* w, GdkEventAny* e, gpointer data);
int main(int argc, char *argv[]) {
//Create widgets
GtkWidget *window;
gtk_init(&argc, &argv);
//Initialize widgets
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
//Configure widgets
gtk_window_set_title(GTK_WINDOW(window), "Hello World");
//Display widgets
gtk_widget_show(window);
//Set up signals
gtk_signal_connect(GTK_OBJECT(window), "delete_event", GTK_SIGNAL_FUNC(delete_event_cb), NULL);
gtk_main();
return 0;
}
static gint delete_event_cb(GtkWidget* w, GdkEventAny* e, gpointer data) {
gtk_main_quit();
turn FALSE;
}
I am using the following command in bash:
g++ `pkg-config --libs --cflags gtk+-3.0` main.c -o binary
I do have the developer version of gtk+ 3.0 installed. Any help is greatly appreciated.
Edit: This is the error message I get:
main.c: In function ‘int main(int, char**)’:

I solved it by myself, but it was difficult to find out how. I gave the wrong order of arguments to g++ and missed an argument as well. This is the bash command that worked for me:
g++ `pkg-config --libs --cflags gtk+-3.0` main.c -o binary `pkg-config --libs gtk+-3.0`
