c++ - 使用启用了 c++11 的 clang 进行编译失败

Question

具有以下test.cpp:

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

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

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

要使 clang(或 gcc)在 C++11 模式下工作可以做什么？

Answer 1

clang 适用于 C。对于 C++，请使用 clang++。

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