dbus_connection_setup_with_g_main()的有关问题

dbus_connection_setup_with_g_main()的问题
Hi, 

I meet a build error says: 'dbus_connection_setup_with_g_main' was not declared in this scope. 

I have included the following headfiles, and used the gcc option: `pkg-config --cflags --libs dbus-glib-1` 

#include <glib.h> 
#include <dbus/dbus.h> 
#include <dbus/dbus-glib.h> 

But, some other APIs in the same code can be found by gcc, such as:dbus_bus_add_match(), dbus_connection_add_filter(), g_main_loop_new() and g_main_loop_run() 

Any suggestion? Thank you very much!
