How do I update my compiler to use C++11 features?

I tried to get myself into C++ and purchased the book "Programming - Principles and Practice Using C++" by Bjarne Stroustrup.

When I tried to get compile the following source code:

#include "std_lib_facilities.h"
int main(){
    cout<<"Hello, World!\n";
    keep_window_open();
    return 0;
}

I am getting following compile error:

I get it that my compiler is not using C++11 feature, but I do not know how I can update the compiler. I should let know that I am using a MacOSX (10.10 Yosemite) and tried to compile with xCode and textmate. I even tried to follow this tutorial(https://wiki.helsinki.fi/display/HUGG/Installing+the+GNU+compilers+on+Mac+OS+X), but it did not helped. (At least when I tried to compile with text mate)

I hope you are able to help me. :(

Solution

  • What you need to do is open the project settings -> Build Settings and set C++ Language Dialect to C++11 and the C++ Standard Library to libc++ (LLVM C++ standard library with C++11 support).
