c++ - 如何让easyloggingpp在macosx上工作？

Question

我正在尝试在 MacOSx 上使用 easyloggingpp ( https://github.com/easylogging/easyloggingpp ) 和 clion 中的 clang。仅包含 easyloggingc++.h 文件不起作用，我收到以下错误。

似乎缺少一些符号，但实际上，easyloggingpp只有一个头文件，所以我不确定缺少什么。

Undefined symbols for architecture x86_64:
  "el::base::utils::s_currentHost", referenced from:
      el::base::LogFormat::updateFormatSpec() in main.cpp.o

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

MWE：

#include "easylogging++.h"

int main()
{
     LOG(INFO)<<"Message";
}
