https://svn.boost.org/trac10/ticket/771 <pre class="wiki">Hi, We use the boost version 1.33.1 , which is compiled with STLport. We get the annoyed compilation warning on the spirit/utility/impl/chset/range_run.ipp: &gt; more t.cpp #include "boost/spirit/utility/distinct.hpp" &gt; g++ -I&lt;path_to_STLport&gt;/5.0.1/stlport - I&lt;path_to_boost&gt;/1.33.1_with_stlport_5.0.1/include -c t.cpp /p/dt/cad/i386_linux26/STLport/5.0.1/stlport/stl/_algo base.h: In function `const _Tp&amp; stlp_std::min(const _Tp&amp;, const _Tp&amp;) [with _Tp = wchar_t]': /p/dt/cad/i386_linux26/boost/1.33.1_with_stlport_5.0.1 /include/boost/spirit/utility/impl/chset/range_run.ipp :69: instantiated from `void boost::spirit::utility::impl::range&lt;CharT&gt;::merge (const boost::spirit::utility::impl::range&lt;CharT&gt;&amp;) [with CharT = wchar_t]' /p/dt/cad/i386_linux26/boost/1.33.1_with_stlport_5.0.1 /include/boost/spirit/utility/impl/chset/range_run.ipp :109: instantiated from `void boost::spirit::utility::impl::range_run&lt;CharT&gt;::merge (typename stlp_std::vector&lt;boost::spirit::utility::impl::range&lt;C harT&gt;, stlp_std::allocator&lt;boost::spirit::utility::impl::rang e&lt;CharT&gt; &gt; &gt;::iterator, const boost::spirit::utility::impl::range&lt;CharT&gt;&amp;) [with CharT = wchar_t]' /p/dt/cad/i386_linux26/boost/1.33.1_with_stlport_5.0.1 /include/boost/spirit/utility/impl/chset/range_run.ipp :137: instantiated from `void boost::spirit::utility::impl::range_run&lt;CharT&gt;::set (const boost::spirit::utility::impl::range&lt;CharT&gt;&amp;) [with CharT = wchar_t]' /p/dt/cad/i386_linux26/boost/1.33.1_with_stlport_5.0.1 /include/boost/spirit/utility/impl/chset/basic_chset.i pp:49: instantiated from `void boost::spirit::basic_chset&lt;CharT&gt;::set(CharT) [with CharT = wchar_t]' /p/dt/cad/i386_linux26/boost/1.33.1_with_stlport_5.0.1 /include/boost/spirit/utility/impl/chset.ipp:117: instantiated from `boost::spirit::chset&lt;CharT&gt;::chset (CharT) [with CharT = wchar_t]' /p/dt/cad/i386_linux26/boost/1.33.1_with_stlport_5.0.1 /include/boost/spirit/utility/chset.hpp:132: instantiated from here /p/dt/cad/i386_linux26/STLport/5.0.1/stlport/stl/_algo base.h:121: warning: returning reference to temporary Is it possible to avoid or to suppress this warning?

The error seems to point to their header files. Anyway, The proper forum to post the problem to is Spirit's mailing list: https://lists.sourceforge.net/lists/listinfo/spirit-general I am closing this for now. If you have follow up questions, please post to the list. </pre> Ticket
