https://svn.boost.org/trac10/ticket/3344 <p> As mentioned in the mailing list thread @ <a class="ext-link" href="http://www.nabble.com/-1.40.0--Beta-1-release-candidate-available-td24902288.html"><span class="icon">​</span>http://www.nabble.com/-1.40.0--Beta-1-release-candidate-available-td24902288.html</a>, the signals lib fails to build as a DLL in msvc-10.0 beta 1. </p> <p> This looks like the same problem as <a class="reopened ticket" href="https://svn.boost.org/trac10/ticket/1499" title="#1499: Bugs: xxx is not a member of 'boost::signals::detail::named_slot_map_iterator (reopened)">#1499</a>. Changing the two workarounds mentioned there to test _MSC_VER &lt;= 1600 allows the lib to build. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/3344 Trac 1.4.3 Richard Webb <richard.webb@…> Tue, 10 Nov 2009 13:18:42 GMT https://svn.boost.org/trac10/ticket/3344#comment:1 https://svn.boost.org/trac10/ticket/3344#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">fixed</span> </li> </ul> <p> Looks like this has been fixed in <a class="changeset" href="https://svn.boost.org/trac10/changeset/57478" title="Signals: merging fix for VS2010 from trunk">[57478]</a> </p> Ticket
