I am writing a program that will use the array container of the C++

  • 0

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>

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$

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?

EDIT:

I have found the location of array on my computer

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

knowing that, what should I do?

    <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
