Errori del compilatore dopo l'aggiornamento a Opencv 2.4.5 su iOS. C'è una soluzione rapida a questi problemi?

Question

Dopo aver aggiornato la versione openCV su un progetto iOS esistente, ottengo i seguenti problemi. Ho provato a giocare con la versione del compilatore e alcune altre impostazioni, ma non ho trovato una soluzione.

Grazie.

Answer 1

mi è stato accidentalmente incluso il file eseguibile OpenCV Unix al posto del quadro (nei quadri legati e le librerie sezione). Dovevo anche includere il file libC++. Dylib come menzionato in this answer.
