LinuxQuestions.org - Building with clang for new C++ standard

I am using the 32-bit version of Fedora 16 on an Intel system. This simple C++ program:

Code:

#include <memory>

#include <iostream>



int main()

{

        auto value = std::make_shared<int>(42);



        std::cout << "The value is " << *value << std::endl;



        return 0;

}

compiles fine using GCC with the following options:

Quote:

g++ -g -Wall -pedantic -ansi -std=c++0x -o Value Value.cpp

When I try to build using clang, I get errors. As near as I can tell clang seems to use the same command line arguments as GCC. I tried building the program using:

Code:

clang++ -g -Wall -pedantic -ansi -std=c++0x -o Value Value.cpp

and I got these errors.

What is needed to use clang for building C++ program that use features from the new C++ standard?
