C++/CX

Question

#ifndef GAMESCREEN_H
#define GAMESCREEN_H

#include "Screen.h"

ref class GameScreen sealed : public Screen
{
public:
	GameScreen();
	~GameScreen();

public:
	virtual void Initialize() override;
	virtual void Update(float timeTotal, float timeDelta) override;
	virtual void Render() override;
};

#endif










#ifndef SCREEN_H
#define SCREEN_H

#include "DirectXBase.h"

ref class Screen : DirectXBase
{

public:
	virtual void Initialize();
	virtual void Update(float timeTotal, float timeDelta);
	virtual void Render() override;
};

#endif

This is more of a C++ components extension question, but it's related to DirectX so I'll ask it here. I'm still having some trouble working with C++/CX and declaring ref classes. I'm getting some constructor-related linker errors from the GameScreen class. Any help?

Error 3 error LNK2019: unresolved external symbol "private: __cdecl GameScreen::~GameScreen(void)" (??1GameScreen@@A$AAA@XZ) referenced in function

Error 4 error LNK2001: unresolved external symbol "private: __cdecl GameScreen::~GameScreen(void)" (??1GameScreen@@A$AAA@XZ) C:\Users\Jeffery\Documents\Visual Studio 2012\Projects\SSS Engine\SSS Engine\Game.obj"public: virtual void __cdecl GameScreen::[Platform::IDisposable]::<Dispose>(void)" (?<Dispose>@?QIDisposable@Platform@@GameScreen@@U$AAAXXZ) C:\Users\Jeffery\Documents\Visual Studio 2012\Projects\SSS Engine\SSS Engine\System.obj

Answer 1

Hello,

I cannot reproduce your issue on my site. Would you please provide us the whole codes to reproduce this issue,

You can upload your project to skydriver
http://skydrive.live.com/

It is not necessary that you send out the whole of your project. We just need a simplest sample to reproduce the problem. You can remove any confidential information or business details from it.

Best regards,
Jesse

It was extremely simple, just no implementation of the constructor.  Thanks, anyway.
