Erreur de typage

Bonjour,
Je rencontre des problèmes avec le code suivant, je ne comprends pas pourquoi le compilateur ne reconnaît pas les différents types alors que je les ai déclarés sur le même fichier.
Je ne vois pas de possibilité d'une boucle infinie.

J'obtient l'erreur suivante :

Code:

1
2
../src/core.h:87:*error:*ISO*C++*forbids*declaration*of*'Playbox'*with*no*type
../src/core.h:87:*error:*expected*';'*before*'*'*token

alors que j'ai bien défini la classe Playbox à la ligne 29;

De plus cela arrive pour toute les classes du fichier

Merci
