如何在M1 Mac上用gcc-11修复链接器错误

Question

在M1 Mac上，我安装了gcc：

$ brew install gcc
$ brew link gcc

我想要openmp和C++ 11。但是当我试图编译更简单的hello world时：

#include <iostream>

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

我收到链接错误：

Undefined symbols for architecture arm64:
  "__ZNSolsEPFRSoS_E", referenced from:
      _main in cckQ2KfV.o
  "__ZNSt8ios_base4InitC1Ev", referenced from:
      __Z41__static_initialization_and_destruction_0ii in cckQ2KfV.o
  "__ZNSt8ios_base4InitD1Ev", referenced from:

      _main in cckQ2KfV.o
ld: symbol(s) not found for architecture arm64
collect2: error: ld returned 1 exit status

我怎么才能解决这个问题？
