需要帮助在Windows上正确设置CLANG

Question

I need some help to set up clang on windows properly.

I have visual studios 2015 installed. And the Windows SDK. I recently installed Clang, and ran a very basic hello world through it to make sure it's working correctly. And it gave me an error I can't make any sense out of.

Visual Studios will handle this just fine.

Here is the error output I've received from clang:

Microsoft Windows [Version 10.0.14393]

C:\Users\Leo>cd C:\Users\Leo\Desktop\Sandbox

C:\Users\Leo\Desktop\Sandbox>clang++ hello.cpp
In file include d from hello.cpp:1:

  'corecrt.h' file not found
#include <corecrt.h>
         ^
1 error generated.

C:\Users\Leo\Desktop\Sandbox>

Line 1 in hello.cpp is just:

#include <iostream>

So this error isn't making sense to me.

Answer 1

Type echo %INCLUDE% at the command prompt. To see your INCLUDE path.

Check to make sure your INCLUDE environment variable isn't set to a path that contains a Visual Studio path. Probably will need to do the same for the LIB environment variable as well.

Answer 2

I recently got it to work correctly, and compile windows applications. Including Directx11 and Directx12.

Turns out you would need to build Clang under Visual Studios after generating a Cmake project. If you wish to default to 64bit, you need to specify the 64bit version of Visual Studios.

Once it's compiled, you need to run clang-cl under the VSbuild tools.
