Problema a compilare classi in qt

[murabio]

Ogni volta che creo una classe mi ritornano 4 link error, ad esempio:

1>AddressBook.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall AddressBook::metaObject(void)const " (?metaObject@AddressBook@@UBEPBUQMetaObject@@XZ)
1>AddressBook.obj : error LNK2001: unresolved external symbol "public: virtual void * __thiscall AddressBook::qt_metacast(char const *)" (?qt_metacast@AddressBook@@UAEPAXPBD@Z)
1>AddressBook.obj : error LNK2001: unresolved external symbol "public: virtual int __thiscall AddressBook::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@AddressBook@@UAEHW4Call@QMetaObject@@HPAPAX@Z)
1>AddressBook.obj : error LNK2001: unresolved external symbol "public: static struct QMetaObject const AddressBook::staticMetaObject" (?staticMetaObject@AddressBook@@2UQMetaObject@@B)
1>C:\Users\FABIO2\Documents\Visual Studio 2010\Projects\media_player_1\Debug\media_player_1.exe : fatal error LNK1120: 4 unresolved externals

Qualcuno sa il perchè?

I think you may have forgotten to include QAxContainer.lib in your Additional Dependencies in your link properties of the project.
