Bonjour,
Encore une fois, j'ai de gros problèmes lors de l'écriture de ma classe template.
Voici ma classe:
Le compilateur (g++ 4.4) me donne les erreurs suivantes:

Mon plus gros problème, c'est que je crois que ce code compile sous VS 2008.In file included from Engine/Library.cpp:25:
Engine/Library.h: In destructor ‘Library<T>::~Library()’:
Engine/Library.h:51: error: expected ‘;’ before ‘itPair’
Engine/Library.h:51: error: ‘itPair’ was not declared in this scope
Engine/Library.h: In member function ‘const T* Library<T>::get(const std::string&) const’:
Engine/Library.h:70: error: expected ‘;’ before ‘itT’
Engine/Library.h:72: error: ‘itT’ was not declared in this scope
Engine/Library.h:77: error: ‘itT’ was not declared in this scope
Engine/Library.h: In member function ‘void Library<T>::getValues(std::list<const T*, std::allocator<const T*> >*) const’:
Engine/Library.h:93: error: expected ‘;’ before ‘itItem’
Engine/Library.h:94: error: ‘itItem’ was not declared in this scope
Je souhaite vraiment avoir un code compatible avec les deux compilateurs.
Ce qui me chagrine, c'est que le compilateur indique comme quoi T n'est pas défini, pourtant le template <typename T>.
