The forward reference is actually in wl_message, like this: (define-cstruct _wl_message ((name _string/utf-8) (signature _string/utf-8) (types (_cpointer 'wl_interface)))) (define-cstruct _wl_interface ((name _string/utf-8) (version _int) (method_count _int) (methods _wl_message-pointer) (event_count _int) (events _wl_message-pointer))) I ended up just inlining (_cpointer 'wl_interface) for the forward reference. This ends up creating two (_cpointer 'wl_interface) ctypes, but it's no problem, correct? I don't think it is possible to "reference 'wl_interface-pointer' directly" as you suggest in this case because of the "cannot reference an identifier before its definition" error. -- Anthony Carrico
