It also happens on my machine (gcc 2.91.66).
The immediate and simple solution is to add an: #include "MenuBackend.h"
to the top of src/frontends/Menubar_pimpl.h
The reason for this is line 77 in the Menubar_pimpl.h file that says:
: pimpl_(p), obj_(o) { item_.reset(i); }
specifically the problem is item_.reset(i) which cannot be done without
the full knowledge of the MenuItem class which is not given without the
include directive.
