For sure ... if you've got both libraries .. but if you don't ...

What about a test after that ?

echo -n "checking for  gtk+-2.0 ... "
if pkg-config --exists  gtk+-2.0 ; then
        echo "yes"
else
        echo "no"
        AC_MSG_ERROR(gthread-2.0 not found, please install it)
fi

echo -n "checking for  gthread-2.0 ... "
if pkg-config --exists  gthread-2.0 ; then
        echo "yes"
else
        echo "no"
        AC_MSG_ERROR(gtk+-2.0 not found, please install it)
fi

int main (int argc, char **argv)
{
        gchar ** array;

        // do your stuff
        window = create_window(array);
        ....
}

GtkWidget*
create_window(gchar** array)
{
        // from here you can pass it to callbacks
}


Even better you can create an struct with all the data you need:


typedef struct _MyData {
        gchar ** array;
        ....
        ....
        ....
} MyData;

int main (int argc, char **argv)
{
        gchar ** array;
        MyData *data;

        // do your stuff
        data = g_malloc(sizeof(MyData));
        
        data->array = array;
        window = create_window(data);
        gtk_widget_show(window);

        gtk_main();
        
        // out the main loop free data
        g_free(data);
        
        ....
}

GtkWidget*
create_window(MyData *data)
{
        gchar** array;

        array = data->array;
        // from here you can pass it to callbacks
}

Hope this helps.
