The problem is that filesystem v3's stream extractor treats spaces as separators (which is the right thing to do IMO), so it only extracts "file"...
boost::filesystem::path p("file name"); std::cout << p;
The output is "file name".
That's not what's happening. I wasn't making a bug report for filesystem, it's a problem with the way lexical_cast uses filesystem in program_options. It's more to do with lexical_cast (which is why I asked how it deals with strings, they must have the same problem). The issue came up here: http://lists.boost.org/boost-users/2010/08/61629.php What's happening is something like: std::stringstream ss; boost::filesystem::path p ss << "file name"; ss >> p; Which just reads 'file'. But lexical_cast doesn't do that for strings, so I assume there must be a specialization somewhere. So I wanted to know if something could be added to filesystem or lexical_cast to deal with this case. Or if that's just the way it works, and program_options will have to contain a special case, which would be a pity. Daniel
