标准标头上的Visual Studio 2017错误

Question

我刚刚升级到Visual Studio 2017社区版，我在加载标准头文件时遇到问题。我从各种头文件中得到507个错误。以下是一些片段：

一些错误：

我从未遇到过Visual Studio 2015 Community Edition的这个问题。我错过了安装程序中的一些组件吗？任何帮助，将不胜感激。谢谢！

Answer 1

我通过安装Windows Universal CRT SDK组件来消除错误，这增加了对旧版Windows SDK的支持。您可以使用Visual Studio Installer安装它：

如果问题仍然存在，则应更改Visual Studio项目中的目标SDK：检查Windows SDK版本是否为10.0.15063.0。

在：项目 - >属性 - >常规 - > Windows SDK版本 - >选择10.0.15063.0。

然后将找到errno.h和其他标准文件，它将进行编译。

Answer 2

如果上述答案无法解决问题，请检查Windows SDK版本是否为10.0.15063.0。

项目 - >属性 - >常规 - > Windows SDK版本 - >选择10.0.15063.0

在此之后重建解决方案。

Answer 3

我将VS2017从15.2升级到15.8。随着版本15.8这里发生了什么：

项目 - >属性 - >常规 - > Windows SDK版本 - >选择10.0.15063.0不再适合我！我不得不将其更改为10.0.17134.0然后再次构建所有内容。升级后，没有进行此更改，我得到相同的头文件错误。

我会提交这个作为对其他答案之一的评论，但我还没有足够的声誉。

Answer 4

如果有人仍然坚持这一点，我找到的最简单的解决方案是“重新定位解决方案”。在我的例子中，该项目是由SDK 8.1构建的，升级到带有SDK 10.0.xxx的VS2017。

要重新定位解决方案：项目 - >重新定位解决方案 - >“选择已安装的SDK” - >确定

从那以后，您可以简单地构建/调试您的解决方案。希望能帮助到你
