Boost C++ Libraries: Ticket #10567: <boost/asio/spawn.hpp> is not inside <boost/asio.hpp> https://svn.boost.org/trac10/ticket/10567 <p> According to the document, include &lt;boost/asio.hpp&gt; should implicitly include &lt;boost/asio/spawn.hpp&gt;, but actually it is missing in asio.hpp and has to be included explicitly. I am not sure whether this is intended or not. If it is intended, then the document needs to be updated. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/10567 Trac 1.4.3
