https://svn.boost.org/trac10/ticket/5934 <p> In version_1_47_0 and the current head (Revision 74542), <code>boost/math/tools/tuple.hpp</code> includes at line 34 the C++11 header <code>&lt;tuple&gt;</code>, rather than the TR1 header <code>&lt;tr1/tuple&gt;</code>: </p> <pre class="wiki">#elif defined(BOOST_HAS_TR1_TUPLE) #include &lt;tuple&gt; namespace boost{ namespace math{ using ::std::tr1::tuple; // [6.1.3.2] Tuple creation functions using ::std::tr1::ignore; using ::std::tr1::make_tuple; using ::std::tr1::tie; using ::std::tr1::get; // [6.1.3.3] Tuple helper classes using ::std::tr1::tuple_size; using ::std::tr1::tuple_element; }} #elif ... </pre><p> With gcc 4.4.3, without <code>std=c++0x</code> or <code>std=gnu++0x</code> specified, this produces a compatibility warning; other compilers/versions are likely to fail to find the header. </p> <p> Changing the line to: </p> <pre class="wiki">#include &lt;tr1/tuple&gt; </pre><p> makes the compilation (and my unit tests) successful. </p> <p> Cheers! </p> <p> David Oliver. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/5934 Trac 1.4.3 John Maddock Mon, 10 Oct 2011 12:08:11 GMT https://svn.boost.org/trac10/ticket/5934#comment:2 https://svn.boost.org/trac10/ticket/5934#comment:2 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> (In <a class="changeset" href="https://svn.boost.org/trac10/changeset/74891" title="GCC workaround when using TR1 tuple.
