问题描述

编辑



我找到 http://llvm.org/docs/GettingStartedVS.html


因此，clang无法解析C ++标准库包含
与Visual Studio，也不是Windows平台SDK的部分。


因此，如果不支持C ++

p>我从 http://llvm.org/builds/ 安装了clang可视工作室工具链。
使用VS2013，当编译任何c ++头时，我得到几个错误。
例如：

  #include< memory> 
 
 int main（）
 {
 return 0; 
}

这些错误似乎与microsoft的c ++ 14实现有关。
在Visual Studio 2012中不会发生。
在VS2013中切换到工具链 LLVM-vs2012 也可以工作



VS2013 + LLVM-vs2013的错误：

在命令行上运行 clang -v 输出

  clang版本3.4（195641）
目标：i686-pc-win32 
线程模型：posix

任何人都可以重现此错误？如果是，我将在 http://llvm.org/bugs/ 创建错误报告。

Edit

i found http://llvm.org/docs/GettingStartedVS.html

Because of this, clang cannot parse the C++ standard library included with Visual Studio, nor parts of the Windows Platform SDK.

So, if C++ is not supported with Visual Studio headers, should i still write a bug report?

Q:

I installed the clang visual studio toolchain from http://llvm.org/builds/. Using VS2013, i get several errors when compiling any c++ header. For example:

#include <memory>

int main()
{
    return 0;
}

These errors seem to be related to microsofts c++14 implementation. This does NOT occur in Visual Studio 2012. Switching to the Toolchain LLVM-vs2012 in VS2013 also works

running clang -v on the command line outputs

clang version 3.4 (195641)
Target: i686-pc-win32
Thread model: posix

Can any of you reproduce this error? If yes, i would create a bugreport at http://llvm.org/bugs/.
