undefined reference to 'xcb_event_get_label'

I have #included <xcb/xcb.h> and <xcb/xcb_util.h> and linked with -lxcb but I still get an

undefined reference to 'xcb_event_get_label'

I can see the function exists in the header file, and the error indicates a linker error, but what other libraries do I need to link against?
