c++ - Cocos2d-x-铛:错误:链接器命令失败，退出代码为1(使用-v查看调用)

从《 Cocos2d-x入门指南》一书中进行教程（空中曲棍球）时，我在Cocos2d-x（2.1.5）中得到了这些消息。

我已经检查了Xcode中的所有“ #include”，BuildPhases等，并在“编译源代码”（约250个文件）中执行了“验证设置”并屏蔽了Internet，希望有人对此表示赞赏。我尚未在.cpp文件中引用它们。

顺便说一句，这本书中的Cocos2d-x版本与我使用的版本不同，我已经检查了该书的网站，并从作者那里找到了这本书：the Authors comment on the releases for the tutorial(s)

这是我第一次尝试使用非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__

最佳答案

您没有在GameLayer.ccp中实现这些功能。遵循本教程，它将教您如何实现它们。
