C++編譯11由於未能與模板和螺紋

我想按照這個教程http://www.cplusplus.com/reference/thread/thread/C++編譯11由於未能與模板和螺紋

創建一個新線程，以下是相關的代碼，我寫

Game.cpp問題：

Game :: Game (bool isDebug, bool startNew) { 
    // ... 
    std :: thread gameThread(Game :: tick); 
} 

void Game :: tick() { 
    std :: this_thread :: sleep_for(std :: chrono :: seconds (1)); 
    funds += getIncomeRate(); 
}

Game.hpp：

#ifndef Game_hpp 
#define Game_hpp 

#include <thread> 

using namespace std; 

class Game{ 
    public: 
    // ... 
     Game (bool, bool); 
     void tick(); 
}; 

#endif /* Game_hpp */

compil過程中出現了錯誤ING表示，

我不是一般很熟悉C++和模板，我真不明白什麼是錯我的代碼。如果這是一個微不足道的問題，請提前道歉。

你想：

std::thread gameThread(&Game::tick, this); 
//     ^^^   ^^^^

既然你包裝成一個線程的方法是不static（而不是一個自由的功能），你需要給線程構造函數的類實例的引用。
