Boost C++ Libraries: Ticket #9269: boost.exception unqualified enable_if/disable_if causing name clash with boost.test enable_if/disable_if https://svn.boost.org/trac10/ticket/9269 <p> boost/exception/to_string.hpp and boost/exception/info.hpp both use enable_if/disable_if unqualified. This caused ambiguous symbols as boost/test/tree/decorator.hpp defines its own versions: boost::unit_test::decorator::disable_if/enable_if. </p> <p> There also is a related ticket for boost.test: <a class="ext-link" href="https://svn.boost.org/trac/boost/ticket/8679"><span class="icon">​</span>https://svn.boost.org/trac/boost/ticket/8679</a> </p> <p> I would recommend adding boost:: at the beginning. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9269 Trac 1.4.3
