Hi, Actually, I'm only a boost user not a developer. The boost version that I have is 1.33.1. Unfortunately, I can't install the newest cvs version. Can you point to me if there is any workaround to solve this problem? Thanks, Peng On 1/24/07, Sohail Somani <s.somani@fincad.com> wrote:

Well maybe as of a few days ago, but yes. Anyway, you should try to debug it.

Hi,

Are you talking about CVS described at http://www.boost.org/more/getting_started.html#CVS

The boost in CVS should make the following code work, right?

Thanks, Peng

This works for me in CVS.

Hi,

I got the following error for the program list below. Where program_options considers "help" and "help_abc" as ambiguous?

$ ./main --help terminate called after throwing an instance of 'boost::program_options::ambiguous_option' what(): ambiguous option help Aborted

Thanks, Peng

#include <boost/program_options.hpp> namespace po = boost::program_options;

int main(int ac, char* av[]) { po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("help_abc", po::value<int>(), "set compression level") ;

po::variables_map vm; po::store(po::parse_command_line(ac, av, desc), vm); po::notify(vm);

return 0; }
