Używanie klanga z libC++ i C++ 11 z linii poleceń z mac os x

Question

Mam problem z uzyskaniem nawet prostego świata hello do kompilacji z clangiem jeśli włączę C++ 11 i libC++. Na przykład poniższy kod

#include <iostream> 

int main() 
{ 
    std::cout << "Hello, World!" << std::endl; 
    return 0; 
} 

daje następujące wyjście z kompilacji gdy uruchomię clang++ -std=c++11 -stdlib=libc++ main.cpp

kod zostanie skompilowany w porządku, jeśli mogę użyć Xcode i ustawić opcje dla libC++ i C++ 11 wsparcie.

Dziękuję za wszelkie odpowiedzi

Twoje narzędzia wiersza polecenia są nieaktualne. Clang 4.0 dostarczany z Xcode 4.4. Chcesz Clang 4.1, który jest dostarczany z Xcode 4.5. Po zainstalowaniu Xcode, możesz przejść do okna Preferencje, wybrać okienko Pobieranie i zakładkę Komponenty, a tam jest wpis "Narzędzia wiersza poleceń". Po prawej stronie pojawi się przycisk "Install".
