MAC OSX 10.7.4，X code 4.4.1，没有＆LT;阵列GT;头文件？ [英] Mac OSX 10.7.4, Xcode 4.4.1, no <array> header file?

问题描述

我写会使用C ++标准库的容器阵列举办一些对象的程序。但是，每当我尝试包括code的下面一行在我的计划：

I am writing a program that will use the array container of the C++ Standard Library to hold some objects. However, whenever I try to include the following line of code in my program:

#include <array>

我收到以下错误在编译时：

I receive the following error at compile time:

75-143-76-177:soft jeffersonhudson$ g++ mms.cpp -o mms
mms.cpp:5:17: error: array: No such file or directory 
75-143-76-177:soft jeffersonhudson$ 

注释掉的#include让我编译就好了。当然，我可以俯瞰简单的东西？我已经安装在X code中的命令行工具，我还是我失去了一些东西？

Commenting out the #include lets me compile just fine. Surely I am overlooking something simple? I have installed the "Command Line Tools" in Xcode, am I still missing something?

编辑：

我已经找到阵列的位置，我的电脑上

I have found the location of array on my computer

/usr/clang-ide/lib/c++/v1

知道，我该怎么办？

knowing that, what should I do?

推荐答案

＆LT;阵列＆gt;的提供了C ++ 11 ，您需要提供 -std = C ++ 11 标志来启用它，并为相应的库提供 -stdlib = ++的libc 标记。但经X code提供的G ++太旧而没有为C ++ 11多的支持。你可以切换到铛？

<array> is provided in C++11, you need to provide the -std=c++11 flag to enable it, and provide the -stdlib=libc++ flag for the corresponding library. But the g++ provided by Xcode is so old which doesn't have much support for C++11. Could you switch to clang?

clang++ -std=c++11 -stdlib=libc++ mms.cpp -o mms
