不同的IDE產生0錯誤與28錯誤

Question

我試圖從Eclipse移到視覺工作室，因爲我已經被告知它對新手來說更容易中間，我同意我的最初印象。我正在嘗試重建類的經典TicTacToe生成只是作爲測試文件，以獲得IDE的感覺，我在Visual Studio中收到28個錯誤和1個警告，相比之下沒有錯誤和1個警告在Eclipse中...代碼是一模一樣。我完全困惑。

要明確它在Eclipse中編譯和運行，同時在Visual Studio中收到28個錯誤。

這是怎麼發生的？

用Visual C++，當precompiled headers被啓用（它們通常是通過默認，名爲stdafx.h）你的PCH必須包括在每個轉換單元中第一報頭。如果你忘記包含PCH，你會得到一個合理的C1010錯誤告訴你;然而，不幸的是，沒有明智的診斷輸出來告訴你爲什麼當你僅僅以錯誤的順序包含頭文件時失敗。

更改您的訂單類實現TU包括使stdafx.hTicTacToe.h，才能將。有關VC++上下文中預編譯頭文件的更多信息，請參見here。
