These macros have been deprecated. The quick fix for now is to just use the functions gdk_threads_enter/leave instead. They are deprecated as well, but deprecated functions don't cause the build to fail (unless you use -Werror).

thanks, applied Any idea what will be the fix? iirc, without that enter/leave, it will hang. And after looking at gtk/gtkclipboard.c, I copied that without digging the real problem further. It's a bit ugly that we have to call g_main_loop_run()..
