使用c ++ 11启用clang编译失败 [英] Compiling with clang with c++11 enabled fails

问题描述

有以下 test.cpp ：

#include <iostream>
int main() {
        int a{};
        std::cout << "TEST" << std::endl;
}

使用最新的GCC（4.8.0） g ++ test.cpp -std = c ++ 11 （gcc也失败），文件编译。尝试使用最新的clang

When build with the latest GCC (4.8.0) g++ test.cpp -std=c++11 (gcc also fails), the file compiles. Trying to compile with the latest clang

clang version 3.4 (trunk 182322)
Target: x86_64-apple-darwin12.3.0
Thread model: posix

构建失败：

clang test.cpp -std=c++11

clang （或 gcc ）可以在C + +11模式？

What can be done for clang (or gcc) to work in C++11 mode?

推荐答案

clang 使用 clang ++ 。

clang++ test.cpp -std=c++11
