Hi,
I have a few questions about Boost.ProgramOptions pertaining to parsing
an argv that is of wchar_t data type. The first thing that isn't clear
from the examples is whether it's possible at all. The second thing
that isn't clear is how to do it and store string values in std::wstring
variables.
Here are the specifics:
1) How do you use program_options with an argv argument that is a
wchar_t data type?
Like this?
variables_map vm;
store(parse_command_line(argc, argv, desc), vm);
but then the question is how do you store any of the command line values
in wstring variables?
Like this?
options_description desc("allowed options");
desc.add_options()
// First parameter describes option name/short name
// The second is parameter to option
// The third is description
("help,h", "print usage message")
("validate,v", value(&strFile), "validate xml file");
// strFile is a wstring
Well that doesn't work.
2) I am getting 3 link errors when trying the above:
