[Boost-users] [serialization] : compile problem

20 Aug 2011

      Hi All,
I am trying to compile this code to test boost serialization, however
I am getting this error

 Error 5 error C2664: 'boost::mpl::assertion_failed' : cannot convert
parameter 1 from 'boost::mpl::failed
************boost::serialization::is_wrapper<T>::* ***********' to
'boost::mpl::assert<false>::type' c:\program files
(x86)\boost\boost_1_46_1\boost\archive\basic_xml_oarchive.hpp 92

I am using boost 1.46.1, visual studio c++ 2010 express.

Any help will be appreciated.

Thanks,
Kaz
