Boost Program Options链接错误

Question

我在链接-lboost_program_options时遇到问题。我甚至不能编译最小示例first.cpp。

这里是CPP：

#include <boost/program_options.hpp> 
namespace po = boost::program_options; 

#include <iostream> 
#include <iterator> 
using namespace std; 

int main(int ac, char* av[]) 
{ 
    try { 

     po::options_description desc("Allowed options"); 
     desc.add_options() 
      ("help", "produce help message") 
      ("compression", po::value<double>(), "set compression level") 
     ; 

     po::variables_map vm;  
     po::store(po::parse_command_line(ac, av, desc), vm); 
     po::notify(vm);  

     if (vm.count("help")) { 
      cout << desc << "\n"; 
      return 0; 
     } 

     if (vm.count("compression")) { 
      cout << "Compression level was set to " 
       << vm["compression"].as<double>() << ".\n"; 
     } else { 
      cout << "Compression level was not set.\n"; 
     } 
    } 
    catch(exception& e) { 
     cerr << "error: " << e.what() << "\n"; 
     return 1; 
    } 
    catch(...) { 
     cerr << "Exception of unknown type!\n"; 
    } 

    return 0; 
} 

这里是我的输出：

我该如何解决这个问题？

我使用Ubuntu 16.04，英特尔（R）酷睿（TM）i5-6400 CPU @ 2.70GHz

我发现我以前g++-4.8，似乎我升压的版本（1.54.0）要求更高版本。在我切换到g++-5后，它正常编译。
