Apple Mach-O連接器（Id）錯誤！不知道該怎麼辦

首先我知道這個問題已經在互聯網上發佈了很多次，但每次人們似乎給出不同的解決方案，我嘗試了幾個，沒有爲我工作。Apple Mach-O連接器（Id）錯誤！不知道該怎麼辦

所以當我建立我的應用程序我得到這個錯誤：

很多人似乎說，它是與丟失的庫或包含一種特殊的方式一個文件！

注意我用的Box2D的，所以C和C++混合並將文件的擴展名是.mm

這有什麼好做

你已經在這兩個pauseMenu定義的變量屏幕寬度缺少庫和mainMenu。它只應在其中之一中定義。

謝謝，這工作，但後來當我使用這些變量，它說，他們是不確定的！我想如何使用這些變量？ – ahoura

讓我們看看代碼 - 而且很多人似乎認爲它與缺少的庫或包含一個特殊的文件有關！似乎無關你的問題 – Mark

以及代碼很長，但我宣佈2 varars：'int screenWidth = 480; int screenHeight = 320;'在這兩個文件中，只是用它們在屏幕上放置東西，但如果代碼真的需要，那麼我可以把它放在 – ahoura
