Ai posteri, se gli altri suggerimenti non risolvono il problema, ho ottenuto questo errore prima perché accidentalmente ho fatto #include "MyFile.cpp "invece di #include" MyFile.h ". Cambiarlo in .h ha risolto il mio problema. Vale la pena controllare le modifiche più recenti per vedere se l'hai fatto per sbaglio. –
