11启用clang编译失败

本文介绍了使用c ++ 11启用clang编译失败的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

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

Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

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
