This warning did not appear with boost 1.38. </p> <pre class="wiki">#pragma once #include &lt;vector&gt; #include &lt;iostream&gt; #include &lt;boost/foreach.hpp&gt; // Compile with warning level 4: int main () { std::vector&lt;int&gt; list; // warning C4512: 'boost::detail::addr_impl_ref&lt;T&gt;' : assignment operator could not be generated BOOST_FOREACH (const int &amp; e, list) { std::cout &lt;&lt; e &lt;&lt; std::endl; } return 0; } </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/2993 Trac 1.4.3 Eric Niebler Thu, 07 May 2009 17:10:28 GMT https://svn.boost.org/trac10/ticket/2993 https://svn.boost.org/trac10/ticket/2993 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">addressof.hpp.patch</span> </li> </ul> <p> patch to eliminate noisy warning on VC++ </p> Ticket Eric Niebler Thu, 07 May 2009 17:12:35 GMT https://svn.boost.org/trac10/ticket/2993#comment:1 https://svn.boost.org/trac10/ticket/2993#comment:1 <ul> <li><strong>owner</strong> changed from <span class="trac-author">Eric Niebler</span> to <span class="trac-author">Peter Dimov</span> </li> <li><strong>component</strong> <span class="trac-field-old">foreach</span> → <span class="trac-field-new">utility</span> </li> <li><strong>summary</strong> <span class="trac-field-old">BOOST_FOREACH warning in VC9</span> → <span class="trac-field-new">addressof warning in VC9</span> </li> </ul> <p> This warning is actually coming from addressof.hpp, so I'm reassigning and attaching a very simple patch.
