https://svn.boost.org/trac10/ticket/3378 <p> Suddenly and for no discernible reason, merely including any (I assume) boost header file produces the compiler errors below. I was including only boost/math/distributions/binomial.hpp when the problem arose. I tested #include&lt;boost/signal.hpp&gt; alone as well, producing the same errors. Nothing in my own code changed (backup copies that compiled when they were saved won't compile now). I tried rerunning the boostpro installer, but it had no effect. I'm using Visual Studio 2008. </p> <p> 1&gt;C:\Program Files\boost\boost_1_39\boost/detail/interlocked.hpp(57) : error C2373: '_InterlockedIncrement' : redefinition; different type modifiers 1&gt; c:\Program Files\Microsoft Visual Studio 9.0\VC\include\memory(993) : see declaration of '_InterlockedIncrement' 1&gt;C:\Program Files\boost\boost_1_39\boost/detail/interlocked.hpp(58) : error C2373: '_InterlockedDecrement' : redefinition; different type modifiers 1&gt; c:\Program Files\Microsoft Visual Studio 9.0\VC\include\memory(994) : see declaration of '_InterlockedDecrement' 1&gt;C:\Program Files\boost\boost_1_39\boost/detail/interlocked.hpp(59) : error C2373: '_InterlockedCompareExchange' : redefinition; different type modifiers 1&gt; c:\Program Files\Microsoft Visual Studio 9.0\VC\include\memory(995) : see declaration of '_InterlockedCompareExchange' 1&gt;C:\Program Files\boost\boost_1_39\boost/smart_ptr/detail/sp_counted_base_w32.hpp(73) : error C3861: '_InterlockedIncrement': identifier not found 1&gt;C:\Program Files\boost\boost_1_39\boost/smart_ptr/detail/sp_counted_base_w32.hpp(92) : error C2446: '==' : no conversion from 'long' to 'long (<span class="underline">clrcall *)(volatile long *,long,long)' 1&gt;C:\Program Files\boost\boost_1_39\boost/smart_ptr/detail/sp_counted_base_w32.hpp(92) : error C2040: '==' : 'long (</span>clrcall *)(volatile long *,long,long)' differs in levels of indirection from 'long' 1&gt;C:\Program Files\boost\boost_1_39\boost/smart_ptr/detail/sp_counted_base_w32.hpp(92) : error C3861: '_InterlockedCompareExchange': identifier not found 1&gt;C:\Program Files\boost\boost_1_39\boost/smart_ptr/detail/sp_counted_base_w32.hpp(100) : error C3861: '_InterlockedDecrement': identifier not found 1&gt;C:\Program Files\boost\boost_1_39\boost/smart_ptr/detail/sp_counted_base_w32.hpp(109) : error C3861: '_InterlockedIncrement': identifier not found 1&gt;C:\Program Files\boost\boost_1_39\boost/smart_ptr/detail/sp_counted_base_w32.hpp(114) : error C3861: '_InterlockedDecrement': identifier not found </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/3378 Trac 1.4.3 John Maddock Tue, 01 Sep 2009 12:05:28 GMT https://svn.boost.org/trac10/ticket/3378#comment:1 https://svn.boost.org/trac10/ticket/3378#comment:1 <ul> <li><strong>owner</strong> changed from <span class="trac-author">John Maddock</span> to <span class="trac-author">Peter Dimov</span> </li> </ul> <p> No idea, _something_ must have changed.
