Tim,Thank you! It's almost working again as before. Only I was also using positional options (boost::program_options::positional_options_description) in addition to the normal options. So filling the variable map looked like this: /boost::program_options::variables_map vm;// //boost::program_options::store(boost::program_options::command_line_parse r(argc, argv).options(allOptionDescriptions)*.positional(positionalOptionsDescript ion)*.run(), vm);/You don't need that. Simply access the "hpx:positional" command line option (of type vector<string>) which will give you all positional arguments. I added a new example demonstrating this here: https://github.com/STEllAR-GROUP/hpx/blob/master/examples/quickstart/command _line_handling.cpp. HTH Regards Hartmut --------------- http://boost-spirit.com http://stellar.cct.lsu.eduIs it also possible to forward a positional options description?
