sorry, the previus message is eronneous. the right code is #include <iostream> #include #include #include #include <fstream> class A { public: A(){} private: //Serialization tasks friend class boost::serialization::access; template<class Archive> void serialize(Archive & , const unsigned int ) { } }; int main() { std::vector<A> eig; std::cout <> eig; } std::cout <:

Hello

While i was trying to run the folowing code:

#include "FaceBase.h" int main() {  FaceBase< EigMemberProps > F(std::string("facebase.archive"));   return 0; }

I get the error message :

/.../boost/serialization/singleton.hpp:124: static T& boost::serialization::singleton<T>::get_instance() [with T = boost::archive::detail::iserializer >, std::allocator > > > >]: Assertion `! detail::singleton_wrapper<T>::m_is_destroyed' failed.

But the strangest it that this happen before the first instruction (the FaceBase constructor is not call). However, if i retrive the text_oarchive and text_iarchive calls in constructor and destructors, it works fine....

do you have any clue about this error ?

Thanks.
