https://svn.boost.org/trac10/ticket/7366 <p> When trying to build release version (debug version builds successfully) of our library with boost 1.49 I get the following warning: </p> <p> 1&gt;d:\sb\EventEngine_trunk\outputs\intermediates\include\boost/program_options/variables_map.hpp(148) : warning C4275: non dll-interface class 'std::_Container_base_aux' used as base for dll-interface class 'std::_Container_base_aux_alloc_real&lt;_Alloc&gt;' 1&gt; with 1&gt; [ 1&gt; _Alloc=std::allocator&lt;std::pair&lt;const std::string,boost::program_options::variable_value&gt;&gt; 1&gt; ] 1&gt; d:\Software\VS2008\VC\include\xutility(377) : see declaration of 'std::_Container_base_aux' </p> <p> Our software has treat warnings as errors enabled so I have to resort to disabling that compiler warning in order to build. Are there any plans to address this? </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/7366 Trac 1.4.3
