编译错误：无法打开预编译的header.pch-没有这样的文件或目录

Question

我最近购买了Bjarne Stroustrup撰写的文章“编程：使用C ++的原理和实践”，并且一直在关注它。我目前停留在早期项目中，我需要输出一些文本字符串。在Windows 10 Lenovo Yoga 2 Pro笔记本电脑上使用Visual Studio Community 2015更新1，我尝试编译该项目，但遇到了以下错误：

“无法打开预编译的头文件：Debug \ Finding the Upstairs Bathroom.pch'：没有此类文件或目录”。该项目的名称恰当地命名为“ Finding the Upstairs Bathroom.cpp”。这是代码：

// I have the headers "stdafx.h" as well as this specific header lib 
// Bjarne Stroustrup created and which I had linked
// called "../../std_lib_facilities.h", which contains the standard C++ lib functions.

(#) define _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS 1

int main()`// Main function`

{  
    cout << "Take the key out of your right pants pocket\n"; // Outputs string of text

    cout << "Unlock the front door of the house\n";

    cout << "Open the front door and step inside\n";

    cout << "Lock the front door using the key\n";

    cout << "Move up the stairs, taking them two at a time\n";

    cout << "Walk to the second door on the left and face it directly\n";

    cout << "Using the door handle, turn it and push the door forward\n";

    cout << "Enter the bathroom while leaving the door open behind you\n";

    keep_window_open();

    return 0;
}

如果有人能够弄清楚我的错误，我将不胜感激。

Answer 1

确保 StdAfx.cpp>右键单击>属性（与 +enter 不同）具有'Precompiled Header'='Create /Yc'

其余的 .cpp 文件应该有'Precompiled Header'='Use /Yu'

Answer 2

有两种解决方案：

• 重建整个项目。这应该（重新）创建预编译的头文件（或Build/Clean Solution首先选择）。

• 关闭预编译的头文件。Project settings / C/C++ / Precompiled headers / Not Using Precompiled Headers。
