Boost :: filesystem在OSX中返回工作目录

Question

我在代码中发现了一个错误，导致我无法将结果输出到终端。我让程序在linux中运行（输出目录）;但是，当我在OSX上编译它时，终端在执行pProgram.parent_path().string();后退出报告。

我在OSX中缺少什么阻止Boost 1.54正常运行？我能做些什么让它正常执行？谢谢。

输入

#include <iostream>
#include <cstring>
#include <boost/filesystem.hpp>

int main()
{
  boost::filesystem::path pProgram( boost::filesystem::current_path() );

  std::cout << "\nhello, world - point A!\n";
  std::string workingDirectory = pProgram.parent_path().string()
  std::cout << "\nhello, world - point B!\n";

  std::cout << workingDirectory;

  return 0;
}

输出

hello, world - point A!
