https://svn.boost.org/trac10/ticket/5828 <p> Hi, </p> <p> I am trying to compile my old code in new OS ( HP-UX 11.31 Itanium version ) with combination of aCC compiler. We are using boost 1.31.0 version. We are facing the boost error during compilation. But the same error is not happening in old server. Can you please help us to fix this issue ? </p> <p> "/opt/app/q1app2c4/boost-1.47.0/boost/any.hpp", line 125: error <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/2070" title="#2070: Tasks: Clean up tools list in web site doc section.

I can't tell you why the type is incomplete, but my best guess is that your code is incorrect and it happened to work with the old compiler because of the order in which it instantiated templates. </p> Ticket
