Template problem

[might]

class CAnyBaseClass
{
public:
CAnyBaseClass();
~CAnyBaseClass();
};

// Definitions ...

template<class BASE>
class CMyClass : public BASE
{
public:
CMyClass();
~CMyClass();
};

// Definitions etc...


...

CMyClass<CAnyBaseClass>* pMyClass = new CMyClass<CAnyBaseClass>;

causes LNK2019 linker error.

I don`t know what to do!
Please, help !

prolly your defintions there which you haven't posted

[might]

With definitions I mean definitions of constructor and destructor

CAnyBaseClass::CAnyBaseClass()
{
}

CAnyBaseClass::~CAnyBaseClass()
{
}

and

CMyClass::CMyClass()
{
}

CMyClass::~CMyClass()
{
}

I have just written them only to avoid compiler error, so I haven`t written any specific code inside them.

I tried to put the defintions in the header file of the class, and that avoided the error. But when they were in the .cpp file, linker gives error.

[kedaman]

don't forget that CAnyBaseClass is a template class, the function definitions are thus templates as well

ALL template code goes in headers, always. Since the template code is only compiled when it is used in your program, if you put it in a source file, it wont be found when the compiler tries to compile it. It will compile, since the prototype exists, but the implementation is not there.

Thanks a lot!
