Undefined symbol ‘IA__gdk_drag_context_get_device’

Question

I get those two errors when trying to compile GTK+:

../../gdk/gdkaliasdef.c:1142: error: ‘gdk_drag_context_get_device’ aliased to undefined symbol ‘IA__gdk_drag_context_get_device’
../../gdk/gdkaliasdef.c:1145: error: ‘gdk_drag_context_set_device’ aliased to undefined symbol ‘IA__gdk_drag_context_set_device’

those lines are:

#undef gdk_drag_context_get_device 
extern __typeof (gdk_drag_context_get_device) gdk_drag_context_get_device __attribute((alias("IA__gdk_drag_context_get_device"), visibility("default")));

#undef gdk_drag_context_set_device 
extern __typeof (gdk_drag_context_set_device) gdk_drag_context_set_device __attribute((alias("IA__gdk_drag_context_set_device"), visibility("default")));

... in gdkaliasdef.c.

How can I fix it?

Thanks
