このコードで私は巨大なエラーを受け取ります

static void ParseTheCommandLine(int argc, char *argv[])
{
int count;
int seqNumber;

namespace po = boost::program_options;

std::string appName = boost::filesystem::basename(argv[0]);

po::options_description desc("Generic options");
desc.add_options()
("version,v", "print version string")
("help", "produce help message")
("sequence-number", po::value<int>(&seqNumber)->default_value(0), "sequence number")
("pem-file", po::value< vector<string> >(), "pem file")
;

po::positional_options_description p;
p.add("pem-file", -1);

po::variables_map vm;
po::store(po::command_line_parser(argc, argv).
          options(desc).positional(p).run(), vm);
po::notify(vm);

if (vm.count("pem file"))
{
    cout << "Pem files are: "
         << vm["pem-file"].as< vector<string> >() << "\n";
}

cout << "Sequence number is " << seqNumber << "\n";

exit(1);

ベクトルは実装しませんostream & operator<<(std::ostream &)。

あなたはおそらくするべきです：

cout << "Pem files are: ";
for (auto & x : vm["pem-file"].as< vector<string> >())
    cout << x << "\n";
