https://svn.boost.org/trac10/ticket/4059 <p> Boost is detecting exception support (or not) and trying to redefine BOOST_NO_EXCEPTIONS which results in a warning if BOOST_NO_EXCEPTIONS is explicitly specified as a compilation flag. </p> <p> I would argue that BOOST_NO_EXCEPTIONS (from upstream) should be observed even if exception support is available. </p> <p> Trivial patch attached. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/4059 Trac 1.4.3 nigels@… Sat, 03 Apr 2010 19:39:28 GMT https://svn.boost.org/trac10/ticket/4059 https://svn.boost.org/trac10/ticket/4059 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">boost_config_gcc.diff</span> </li> </ul> <p> Avoid redefining BOOST_NO_EXCEPTIONS </p> Ticket John Maddock Wed, 05 May 2010 17:55:18 GMT https://svn.boost.org/trac10/ticket/4059#comment:1 https://svn.boost.org/trac10/ticket/4059#comment:1 <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/61791" title="Only define BOOST_NO_EXCEPTIONS if not already defined - fixes #4059.">[61791]</a>) Only define BOOST_NO_EXCEPTIONS if not already defined - fixes <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/4059" title="#4059: Patches: config/compiler/gcc.hpp should not redefine BOOST_NO_EXCEPTIONS (closed: fixed)">#4059</a>. </p> Ticket
