我在我的代码中发现了一个错误，它阻止我将结果输出到终端。我让程序在 linux 中按需要运行（输出目录）；但是，当我在 OSX 上编译它时，终端在执行pProgram.parent_path().string();.

我在 OSX 中缺少什么会阻止 Boost 1.54 正确运行，我该怎么做才能让它正确执行？谢谢你。

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!

临qmake文件
