Code snippet is below...basically I have 2 options I want to process "host,s" & "help,h". I would like to process options like this: for host: --host, -host, -s for help: --help, -help, -h Maybe I setup the opt_style variable wrong or is this correct behavior? I'm using boost 1.33.1 when i run the program:

po.exe -host localhost -h *** Command line processing error: ambiguous option h

thanks for any help, -Santosh ====================================================== #include <iostream> #include <string> #include "boost/program_options.hpp" using namespace std; namespace po = boost::program_options; int main(int, char *[]) { po::variables_map vm; po::options_description desc("Options"); try { string strHostname; desc.add_options() ("host,s", po::value<string>(&strHostname), "") ("help,h", "Show this help message"); po::options_description cmdline_options; cmdline_options.add(desc); int opt_style = (po::command_line_style::unix_style | po::command_line_style::allow_long_disguise | po::command_line_style::allow_slash_for_short); po::store(po::parse_command_line(argc, argv, cmdline_options, opt_style), vm); po::notify(vm); cout << "host: " << strHostname << endl; if( vm.count("help") ) cout << "help is true" << endl; } catch(exception &e) { cout << endl << "*** Command line processing error: " << e.what() << endl; } return 0; } __________________________________________________ Do You Yahoo!?
