https://svn.boost.org/trac10/ticket/749 <pre class="wiki">http://boost.org/doc/html/program_options/ howto.html#id2716386 There are two typos in the second (last) code block in "Allowing Unknown Options". 1. The function name collect_arguments should read collect_unrecognized. 2. The first parameter refers to parsed_options field name "option" rather than "options". So the following block vector&lt;string&gt; to_pass_further = collect_arguments(parsed.option, include_positional); should read as follows vector&lt;string&gt; to_pass_further = collect_unrecognized(parsed.options, include_positional); </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/749 Trac 1.4.3 Vladimir Prus Thu, 28 Jun 2007 06:54:25 GMT https://svn.boost.org/trac10/ticket/749#comment:1 https://svn.boost.org/trac10/ticket/749#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">assigned</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> <span class="trac-field-old">None</span> → <span class="trac-field-new">fixed</span> </li> <li><strong>severity</strong> → <span class="trac-field-new">Cosmetic</span> </li> </ul> <p> Fixed in CVS HEAD. </p> Ticket
