Re: [Boost-users] Persisting __int64 (or long long) with boost::serialization?

The code as posted looks solid to me. This might be trivial, but Checked that the code is actually included in the place where the serialization is instatiated ? Have you tried replacing your typedefs with __int64 ? (thus removing the typedefs) Or maybe use the STRONG_TYPEDEF macro that comes with serialization lib (undocumented i think).

Thanks Steve, I tried that but I'm still getting no joy ...

Could it be that unsigned __int64 is not a class, but an integral data type?

I have two typedefs of unsigned __int64 type: TimeCode and FileSize. I'm assuming the compiler is smart enough to infer the difference.

I've changed my source according to the docs:

namespace boost { namespace serialization {

template<class Archive> void save(Archive & ar, const unsigned __int64& big, unsigned int version) { ar & sizeof(big); ar.save_binary(&big, sizeof(big)); }

template<class Archive> void load(Archive & ar, unsigned __int64& big, unsigned int version) { size_t size = sizeof(big); ar.load_binary(&big, size); }

} };

BOOST_SERIALIZATION_SPLIT_FREE(unsigned __int64)

And it still complains with VideoStorage.cpp 1>c:\src\storagetest\storagetest\videostorage.h(66) : error C2679: binary '&' : no operator found which takes a right-hand operand of type
