Title Body

I get a compiler warning, that I don't understand in that context. When I compile the "Child.cpp" from the following code. (Don't wonder: I stripped off my class declarations to the bare minimum, so the content will not make much sense, but you will see the problem quicker). I get the warning with Visual Studio 2003 and Visual Studio 2008 on the highest warning level. The code AbstractClass.h: #include <iostream> template<typename T> class AbstractClass { public: virtual void Cancel(); // { std::cout << "Abstract Cancel" << std::endl; }; virtual void Process() = 0; }; // Outside definition. If I comment out this and take the inline // definition like above (currently commented out), I don't get // a compiler warning. template<typename T> void AbstractClass<T>::Cancel() { std::cout << "Abstract Cancel" << std::endl; } Child.h: #include "AbstractClass.h" class Child : public AbstractClass<int> { public: virtual void Process(); }; Child.cpp: #include "Child.h" #include <iostream> void Child::Process() { std::cout << "Process" << std::endl; } The warning The class "Child" is derived from "AbstractClass". In "AbstractClass" there's the public method "AbstractClass::Cancel()". If I define the method outside of the class body (like in the code you see), I get the compiler warning... AbstractClass.h(7) : warning C4505: 'AbstractClass::Cancel' : unreferenced local function has been removed with [T=int] </blockquot
