1068,Mersenne twister disables streaming for Visual C++,s.somani@…,No-Maintainer,"boost/mersenne_twister.hpp disables the streamable concept because boost config machinery says that vc 7.1/8 cannot handle member template friends. This appears not to be the case.

To work around it, I do the following:

// This hack is necessary because boost thinks that Visual C++ still
// cannot handle member function templates
// It is needed to make mersenne_twister streamable
#include <boost/config.hpp>
#if defined(BOOST_MSVC) && defined(BOOST_NO_MEMBER_TEMPLATE_FRIENDS)
#  undef BOOST_NO_MEMBER_TEMPLATE_FRIENDS 
#  define FINCAD_BOOST_RNG_HACK
#endif

#include <boost/random/mersenne_twister.hpp>

#ifdef FINCAD_BOOST_RNG_HACK
#  define BOOST_NO_MEMBER_TEMPLATE_FRIENDS
#  undef FINCAD_BOOST_RNG_HACK
#endif

I don't know how you would fix it for the twister. It really sounds like a config machinery issue but it affects the mersenne twister code negatively.",Bugs,closed,To Be Determined,random,,Problem,fixed,,
