Visual Studio 2017 errors on standard headers

Question

I just upgraded to Visual Studio 2017 Community Edition and I have trouble loading standard header files. I get 507 errors from various header files. Here are some snippets:

Answer 1

I got the errors to go away by installing the Windows Universal CRT SDK component, which adds support for legacy Windows SDKs. You can install this using the Visual Studio Installer:

If the problem still persists, you should change the Target SDK in the Visual Studio Project : check whether the Windows SDK version is 10.0.15063.0.

In : Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0.

Then errno.h and other standard files will be found and it will compile.
