我正尝试从 Eclipse 转移到 visual studio，因为有人告诉我新手更容易进入中级，我同意我的初步印象。我正在尝试重建一个经典的 TicTacToe 版本，就像一个测试文件一样，以感受 IDE，我在 Visual Studio 中收到 28 个错误和 1 个警告，而在 Eclipse 中没有错误和 1 个警告......代码是一模一样。我完全糊涂了。
需要明确的是，它在 Eclipse 中编译和运行，同时在 Visual Studio 中收到 28 个错误。
为什么会这样？

最佳答案
使用 Visual C++，当 precompiled headers已启用(通常默认情况下，名为 stdafx.h)您的 PCH 必须是每个翻译单元中包含的 第一个 header 。如果您忘记完全包括 PCH，您会得到一个合理的 C1010错误地告诉你；然而，不幸的是，当您只是以错误的顺序包含 header 时，没有明智的诊断输出可以告诉您为什么事情会失败。
更改包含在类实现 TU 中的顺序，以便 stdafx.h 包含在 TicTacToe.h 之前。更多关于 VC++ 上下文中的预编译头文件的阅读可以在 here 中找到。 .
