Clang：无法找到C ++ 11标题 [英] Clang : Failed to find C++11 headers

问题描述

我试图建立所有的例子在Crow库中与铛3.6和我可以看到CC / CXX已被发现正确使用铛3.6。它使用cmake，我不是很熟悉。

I am trying to build all the examples in the Crow library with clang 3.6 and I can see the CC/CXX has been found properly by using clang 3.6. It uses cmake which I am not quite familiar with.

但它没有找到C ++ 11标题。

However it failed to find C++11 headers.

错误如下：

未来的档案找不到

'future' file not found

似乎libstdc ++没有正确指定，或者有些人认为它需要自己编译libstdc ++。

It seems that the libstdc++ is not specified properly, or some people reckon it needs to build the clang libstdc++ myself.

任何人都可以散发一些光这将是非常感激。

Anyone can shed some light on this will be much appreciated.

推荐答案

所以基于前面的注释，问题是，你不启用C ++ 11

So based on the previous comment the issue is that you don't enable the C++ 11 mode in Clang.

在引用的问题，问题只是你不向Clang（或将来的GCC）寻找C ++头。

As in referenced question, the issue is simply that you do not say to Clang (or in future for GCC) to look for C++ headers.

Clang的命令行是gcc兼容的，因此您必须通过followinf命令行开关启用C ++ 11支持

"Clang's command line is gcc-compatible so you have to enable C++11 support via the followinf command-line switch"

-std=c++11

如果在这之后你所需要做的就是编写你的C ++ 11代码。如果你使用Makefile，你应该添加到你的CXX参数命令行切换到Clang。

If after this you all you have to do is to write your C++ 11 code. If you use Makefiles you should add to your CXX arguments the command line switch to Clang.
