[Boost-users] [interprocess] warning C4251: need dll-interface

I've defined a class to use within shared memory, and I've decorated it with a Windows _declspec(export) to expose it from a DLL. When I compiled with VC 2008, I got this warning: Warning C4251: class 'boost::interprocess::vector' needs to have dll-interface to be used by clients of 'MyClass' I searched boost user archives for any discussion of this, and in the context of boost.signals I've seen someone comment to simply disable the warning with: #pragma warning (disable: 4251) Std::list talkers; #pragma warning (default: 4151) Does this also apply to boost.interprocess? Is it really safe to ignore this warning and continue to use the interprocess code from within a DLL? Brent Arias
