Xcode编译器找不到C ++ 11包括 [英] Xcode compiler cannot find C++ 11 includes

问题描述

我在Visual Studio 2012中开发了一些类，它们大量使用C ++ 11特性，并且使用了新的std特性，如线程和互斥。原因是平台无关。试图将代码移植到OSX Xcode编译器5.0无法打开以下包括：

I developed some classes in Visual Studio 2012 which make heavy use of C++11 features and also uses new std features like threads and mutex. The reason was to be platform independent. Trying to port the code to OSX the Xcode compiler 5.0 cannot open following includes:

#include <chrono>
#include <thread>
#include <functional>
#include <mutex> 

我已经将构建设置切换到C ++ 11并搜索usr / include路径include 。

I already switch the build settings to C++11 and searched the usr/include path for the includes. Please do not suggest boost as I try to eliminate it from my projects.

推荐答案

您需要两个 - std = c ++ 11 和 -stdlib = libc ++ ：

$ cat cpptest.cpp
#include <chrono>
#include <thread>
#include <functional>
#include <mutex>

int main() {
    return 0;
}

$ clang -o cpptest -std=c++11 -stdlib=libc++ cpptest.cpp
$ echo $?
0
