As-tu essayer de simplifier le problème ? Parce que personnellement démêler l'utile et l'inutile de tout le code que tu donnes, j'ai pas vraiment envie de le faire.

J'arrive pas à suivre les inclusions de ton code (tu ne donnes pas les noms des fichiers que tu mets, c'est pas évident). Mais le problème est probablement que tu utilises la classe BoundingSphere sans avoir inclut sa définition.

Cette ligne :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

#define BVKEY REGISTER_KEY(BOUNDINGVOLUMEKEY, odfaeg::BoundingVolume, odfaeg::BoundingBox, odfaeg::BoundingSphere)

Devrait pas plutôt être :

Code :

2
#define BVKEY 
REGISTER_KEY(BOUNDINGVOLUMEKEY, odfaeg::BoundingVolume, odfaeg::BoundingBox, odfaeg::BoundingSphere)

Sur deux lignes ?

Tu as aussi des warning plutôt gênant, c'est à cause de code en cours de construction ?

Invité · 18/08/2014, 21h35

Oui le code est en cours de construction.

Avec BoundingBox il me compile sans problème même si je n'ai que la forward déclaration par contre il a besoin de la déclaration complète de la classe BoundingSphere et c'est ça que je ne comprends pas.

Sinon c'est bien une seule ligne pour la macro, car, je veux pouvoir la redéfinir dans le main avant d'inclure BoundingVolume.h pour changer la déclaration de la structure dans serialization.cpp. (Car mes fichiers sont dans une librairie)

Sinon au niveau des inclusions j'ai deux fichiers : serialization.h et serialization.cpp qui inclu serialization.h

boundingVolume.h include serialization.cpp et boundingBox et boundingSphere (qui héritent de BoundingVolume) inclue boundingVolume.h.

Je ne peux malheureusement pas faire autrement, la classe BoundingVolume à besoin de la définition de la classe Serializer et de son impélementation. (dans serialization.cpp)

Et les classes BoundingBox et BoundingSphere ont besoin de la définition de la classe BoundingVolume, donc, au niveau des include je ne peux rien changer...

Normalement la classe Serializer ne devrait pas avoir besoin de la définition complète de la classe BoundingSphere, tout comme elle n'a pas besoin de la définition complète de la classe BoundingBox.

Je dois avoir foiré quelque part au niveau des définitions et des inclusions dans les classes boundingsphere et boundingbox mais je vois pas très bien ou.

**Flob90** · 18/08/2014, 21h43

Le comportement normal est d'avoir besoin de la définition complète dans ton cas, à cause de ton typeid.

Invité · 18/08/2014, 22h14

Bon bah j'ai inclus boundingSphere.h dans boundingBox.h et maintenant ça compile, je ne comprends pas très bien pourquoi...

Et je n'ai pas la définition complète de la classe dans celle ou je fais le typeid. (Quoi que, en fin de compte, je pense bien que si mais j'ai un peu de mal à m'y retrouver dans mes include là. :/)

Invité · 25/08/2014, 16h29

Finalement j'ai trouvé la solution pour en finir avec ses problèmes de froward déclarations.

1) Je passe la classe généré par la macro template et je al fait héritée du template. (lui même)

#endif // SERIALIZATION_CPP

Ensuite, je dois recherché quel est le 1er fichier.h des classes dérivée, qui inclus le fichier de la classe de base et enfin, inclure tout les .h des autres classes dérivées dans se fichier :

#include "boundingEllipsoid.h"

Et voilà!
Maintenant le code compile sans problème!
