https://svn.boost.org/trac10/ticket/11259 <p> I'm working on porting some code to a platform without a C++11 standard library, and wanted to use the Boost versions of shared_ptr and unique_ptr. Unfortunately code like this doesn't work: </p> <pre class="wiki">namespace mystd { using boost::shared_ptr; using boost::make_shared; using boost::movelib::unique_ptr; using boost::movelib::make_unique; } mystd::unique_ptr&lt;int&gt; load_thing() { return mystd::make_unique&lt;int&gt;(1); } mystd::shared_ptr&lt;int&gt; get_thing() { return load_thing(); } </pre><p> because there is no conversion from movelib::unique_ptr to shared_ptr. </p> <p> I'm happy to submit a patch that adds it but I'm not sure whether it's okay to add a Boost.Move dependency to Boost.<a class="missing wiki">SmartPtr</a>. And if I do that, should I also add move emulation to boost::shared_ptr? C++03 users might like the performance benefit of moving them instead of copying them. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/11259 Trac 1.4.3 Peter Dimov Sun, 03 May 2015 22:15:08 GMT
