Re: [Boost-users] Problem with boost::program_options

It looks like the problem is that you didn't specify a boost_po::value for -i.

    _generic_options.add_options()
        ("input-file,i",boost_po::value<std::string>(), "specify input file")
        ("ops", boost_po::value< std::vector< std::string > >(),
            "specify operators " )
        ;
