"/usr/include/math.h", line 215: Error: The name exception is ambiguous, exception and std::exception. ".../boost/exception/exception.hpp", line 140: Error: The name exception is ambiguous, exception and std::exception. </p> <p> and actually it produces similar error messages for small test like this: </p> <blockquote> <p> namespace boost { </p> <blockquote> <p> class exception; </p> </blockquote> <p> } using namespace boost; #include &lt;algorithm&gt; </p> </blockquote> <p> or like this: </p> <blockquote> <p> class exception; using namespace std; #include &lt;algorithm&gt; </p> </blockquote> <p> Note that in the original boost harness "class exception;" can be found inside: boost/exception/exception.hpp </p> <ol start="2"><li>Cause of the failure. </li></ol><p> This is a C++ vs Unix or Boost vs Unix issue. </p> <p> Standard Unix requires "struct exception" in the global namespace when &lt;math.h&gt; is included. This conflicts with std::exception or boost::exception, but only when there are using-declarations or using-directives that bring std::exception or boost::exception into the global namespace. </p> <p> When &lt;math.h&gt; is included, user code must avoid all of the following at file scope (in the global namespace): using namespace std; using namespace boost; using std::exception; using boost::exception; </p> <ol start="3"><li>Possible Solution. </li></ol><ul><li>Remove line: </li></ul><blockquote> <blockquote> <p> using namespace std; </p> </blockquote> </blockquote> <ul><li>Replace all 'cout' invocations with 'std::cout' </li></ul> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/10975 Trac 1.4.3 Sergey.Sprogis@… Fri, 30 Jan 2015 20:33:45 GMT https://svn.boost.org/trac10/ticket/10975#comment:1 https://svn.boost.org/trac10/ticket/10975#comment:1 <ul> <li><strong>owner</strong> changed from <span class="trac-author">René Rivera</span> to <span class="trac-author">Joel de Guzman</span> </li> <li><strong>component</strong> <span class="trac-field-old">Regression Testing</span> → <span class="trac-field-new">spirit</span> </li> </ul> <p> In addition to fixe inside match_tests.cpp described in original filings, 15 more tests from spirit/classic/test directory listed below should be similarly modified.
