Re: [Boost-users] [program options] count problem

This call I use works for me: po::command_line_parser(argc, ppargv).options(desc).run() Don't know if there is an important difference here, or if what you call is just a wrapper around it, but see if that works for you. Best, Dee On Sat, Feb 2, 2013 at 9:14 PM, Olivier Tournaire wrote:

Oups. Made à mistake ... However the issue is still there:

{ for(unsigned int i=0;i

cout << desc << endl; return 1; }

Hi all,

I am having troubles with program options. I try to test if at least some of the available options are passed on the command line, but fail for some reason using count("option_name"). Here is my code:

int main(int argc, char** argv) { string hierarchy; vector<string> files, directories; double vertical_shift; bool show_progress, single_file, single_dir; int target_EPSG, nb_threads;

po::options_description desc("Allowed options"); desc.add_options() ("help ,h" , "Produce help message") ("hierarchy ", po::value<string>(&hierarchy) , "process a hierarchy) ("file ", po::value(&files) , "process the specified files") ("directory ", po::value(&directories) , "process the specified directories");

po::variables_map vm; try { po::store(po::parse_command_line(argc, argv, desc), vm);

if (vm.count("help")) { cout << desc << "\n"; return 1; }

po::notify(vm); } catch (const po::error &e) { cerr << "Exception caught ! --> " << e.what() << endl; cout << desc << endl; return 1; }

if (vm.count("hierarchy")) { path input_path(hierarchy); // DO STUFF } else if (vm.count("files")) { for(unsigned int i=0;i

I always fall in the "else". What am I doing wrong?

For instance with this command line : ./acute_coordinates_transform --hierarchy ~/work/data/

À other question: is there à way to specify that 1 of the 3 options is required (and only 1)?

Hope you cloud help.

Regards,

Olivier
