singleton déjà défini dans singleton.obj
bonjour,
J'essaye de créer un singleton mais j'ai les erreurs suivantes :
Citation:
cSpectatorController.obj : error LNK2005: "private: static class cApplication * cApplication::_singleton" (?_singleton@cApplication@@0PAV1@A) déjà défini(e) dans cApplication.obj
main.obj : error LNK2005: "private: static class cApplication * cApplication::_singleton" (?_singleton@cApplication@@0PAV1@A) déjà défini(e) dans cApplication.obj
voici le code de mon singleton :

Il me semble pourtant avoir respecté scrupuleusement les indications des différents tutos que j'ai trouvé, mais rien n'y fait.
