Since it wants private access into the class, how would you package it as a separate header?
add "friend class boost::serialization::access;" to the class declaration.

I don't see how that works. If I add friend class boost::serialization::access; inside of the original class declaration, and then outside the class declaration: typedef boost::mt19937 rng_t; namespace boost { namespace serialization { // Serialization template<class Archive> void serialize(Archive & ar, rng &m, const unsigned int /* file_version */){ ar & serialization::make_nvp ("i", m.i); ar & serialization::make_nvp ("x", m.x); } }} This doesn't compile: /usr/local/src/boost.hg/boost/random/mersenne_twister.hpp:209: error: 'int boost::random::mersenne_twister<unsigned int, 32, 624, 397, 31, 2567483615u, 11, 7, 2636928640u, 15, 4022730752u, 18, 3346425566u>::i' is private mod/boost_rand.cc:49: error: within this context
