Re: [Boost-users] [program_options] How do I read a vector of strings?

Hello,

I have been using program_options for a while and it works great. However, I don't know how to make a program which behaves like this:

programname -blah abc -blah def -blah ghi

In my code I would read the option blah as a vector of strings, like:

po::options_description desc("Configuration"); desc.add_options() ("blah", po::value(), "the location of the blah device") ; po::store(po::parse_config_file(config_file, desc), vm); po::notify(vm);

etc.

When I try to compile the code under MSVC++ 7.0 I get this error (among others):

error C2947: expecting '>' to terminate template-argument-list, found '>>'

Is it possible for me to do what I am trying to with the program_options library?

Thanks, -Matt

Instead of 'po::value()', use 'po::value()' - i.e. put a space between the '>' characters. The C++ compiler is seeing '>>' as the right bit-shift operator, not two '>' characters closing the template argument lists. Stuart Dootson
