具有以下test.cpp
:與C++ 11鐺編譯啓用失敗
#include <iostream>
int main() {
int a{};
std::cout << "TEST" << std::endl;
}
當構建了最新的海灣合作委員會(4.8.0)g++ test.cpp -std=c++11
(GCC也失敗),該文件編譯。試圖用最新的鐺編譯
clang version 3.4 (trunk 182322)
Target: x86_64-apple-darwin12.3.0
Thread model: posix
構建失敗:
clang test.cpp -std=c++11

有什麼可以做的clang
(或gcc
)在工作的C++ 11模式?
謝謝,現在看起來很明顯。 – Appleshell
