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

My bad ... As i'm found of comma alignement, there were spaces in the options values. "file" was "file " ... Le samedi 2 février 2013, Olivier Tournaire a écrit :

Thanks Diederick. Did not do the trick. How I can I access the variables stored in vm ?
