Hmmm...I must be missing something very obvious.
Trying your example, I still don't seem to be able to use -config-file, but only --config-file.
Here's my code snippet:

string strConfigFile;
po::options_description desc2;
    ( "config-file", po::value< std::string >( & strConfigFile )->default_value( "jaja" ) );
po::variables_map vm2;
po::store(po::parse_command_line(argc, argv, desc2), vm2);

And this is accepted fine:
--config-file foo

While this throws an 'unkown option -c':
-config-file foo

Any insights into what may be causing such a difference in behaviot?

No, all the args start with a single '-'.


For example, with the following code:


    po::options_description desc;


        ( "config-file", po::value< std::string >( & strConfigFile )->default_value( defaultConfigFilePath.native_file_string() ) );


I am able to call my program with a -config-file my_config_file.cfg command line.

Objet : [Boost-users] [Boost.Program_options] Is there a way to have alloptions specifiedwith a single dash instead of double?


I'm interested in switching over the command line processing of an existing tool to use program_options.
However, all of the args are of the format '-foo -bar -whatever 1' etc.
As far as I can tell from the docs it seems like by default the program_options library assumes args all start with a '--' or have single character short names that start with a single dash. Is there a way to coerce it into the behavior I'm looking for?

Thanks for any tips!
