https://svn.boost.org/trac10/ticket/4267 <p> validation_error constructor signature was changed from </p> <p> validation_error(const std::string &amp;); </p> <p> in boost 1.41.0 </p> <p> to </p> <p> validation_error(kind_t, const std::string &amp; = "", const std::string &amp; = ""); </p> <p> in boost 1.42.0+ </p> <p> validation_error isn't backward compatible now. This way "Custom Validators" section in html-documentations has an wrong example that uses 'validation_error(const std::string &amp;)' signature. And there aren't any examples to use new version of validation_error. </p> <p> <a href="http://www.boost.org/doc/libs/1_43_0/doc/html/program_options/howto.html#id1421830">http://www.boost.org/doc/libs/1_43_0/doc/html/program_options/howto.html#id1421830</a> </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/4267 Trac 1.4.3 Marshall Clow Sun, 05 Dec 2010 20:13:17 GMT https://svn.boost.org/trac10/ticket/4267#comment:1 https://svn.boost.org/trac10/ticket/4267#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">duplicate</span> </li> </ul> <p> This is a duplicate of <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/3992" title="#3992: Bugs: Example in documentation for program_options doesn't compile (closed: fixed)">#3992</a>. </p> Ticket
