Hi; When using boost with visual c++ 2005, I'm getting the following two error: c:\program files\microsoft visual studio 8\vc\include\intrin.h(198) : error C2373: '_InterlockedExchange' : redefinition; different type modifiers c:\program files\boost\boost\detail\interlocked.hpp(60) : see declaration of '_InterlockedExchange'

Has anyone got any ideas what is causing this?

interlocked.hpp(60) for me is: extern "C" long __cdecl _InterlockedExchange( long volatile *, long); intrin.h(198) is: __MACHINEI(long _InterlockedExchange(long volatile *, long)) where __MACHINEI(X) is defined as X; so the two declarations should be the same except for the __cdecl. Are you overriding the default calling convention? _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users __________ Information from ESET NOD32 Antivirus, version of virus signature database 3896 (20090228) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 3896 (20090228) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
