Cocos2d-x-鐺：錯誤：鏈接器命令失敗，退出代碼為1（使用-v查看調用）

Question

從《 Cocos2d-x入門指南》一書中進行教程（空中曲棍球）時，我在Cocos2d-x（2.1.5）中得到了這些消息。

我已經檢查了Xcode中的所有“ #include”，BuildPhases等，並在“編譯源代碼”（約250個文件）中執行了“驗證設置”並屏蔽了Internet，希望有人對此表示贊賞。 我尚未在.cpp文件中引用它們。

順便說一句，本書中的Cocos2d-x版本與我使用的版本不同，我檢查了圖書網站並從作者那里找到了這一點： 作者對本教程的發行版發表了評論

這是我第一次嘗試使用非Objective-C和Cocos2d-x。

GameLayer.h：

#ifndef __GAMELAYER_H__
#define __GAMELAYER_H__

#define GOAL_WIDTH 400

#include "cocos2d.h"
#include "GameSprite.h"

using namespace cocos2d;

class GameLayer : public cocos2d::CCLayer {

GameSprite  *_player1;
GameSprite  *_player2;
GameSprite  *_ball;

CCArray     *_players;
CCLabelTTF  *_player1ScoreLabel;
CCLabelTTF  *_player2ScoreLabel;

CCSize      _screenSize;

int _player1Score;
int _player2Score;

void playerScore (int player);

public:

~GameLayer();

virtual bool init();

static CCScene *scene();

CREATE_FUNC(GameLayer);

virtual void ccTouchesBegan(CCSet* pTouches, CCEvent* event);
virtual void ccTouchesMoved(CCSet* pTouches, CCEvent* event);
virtual void ccTouchesEnded(CCSet* pTouches, CCEvent* event);

void update (float dt);

};

#endif // __GAMELAYER_H__

您沒有在GameLayer.ccp中實現這些功能。 遵循本教程，它將教您如何實現它們。
