Notice that split_free.hpp is for when you have split save/load *freestanding* functions, and split_member.hpp is for when you have split save/load *member* functions. I can't reproduce your error (I don't do Microsoft), but I'll guess that's it, since split_free.hpp isn't required by the code you posted, and that's where your error is coming from. You could also try running the serialization tests on your platform. at $BOOST_ROOT/libs/serialization/test. There are surely a couple of tests in there that demonstrate the technique... troy d. straszheim jason wrote:

Anyway, I am getting a

Error C2780 .\boost_1_32_0\boost\serialization\split_free.hpp(45): error C2780: 'void boost::archive::save(Archive &,const T &)' : expects 2 arguments - 3 provided

message when I use STL containers in Boost and the BOOST_SERIALIZATION_SPLIT_MEMBER() macro in my class. I have found when I don't split the serialize method into load / save methods it works fine. However, I need separate load / save methods as some of the members in my class are not serializable (they are SDL resources, and therefore uploading I need to do some other work to restore these members).

Here is a chunk of example code that fails...

class P { private: int qw;

friend class boost::serialization::access;

template<class Archive> void serialize(Archive& ar, const unsigned int version) { ar & qw; } public: P() : qw(0) {} P(int Qw) : qw(Qw) {} };

typedef std::list<P*> pList;

class Test { pList p;

friend class boost::serialization::access; BOOST_SERIALIZATION_SPLIT_MEMBER()

template<class Archive> void load(Archive& ar, const unsigned int version) { ar & p; }

template<class Archive> void save(Archive& ar, const unsigned int version) const { ar & p; }

public: Test() {} };

Using

Test t; std::ofstream ofs("frameTest"); boost::archive::text_oarchive oa(ofs); oa << t; ofs.close();

creates this error. To me it seems like this might be a library issue. However could someone point out what I am doing wrong if it is me, and if it is a lib issue, could they hint /suggest some sort of cleanish workaround. I am going to mess about and hack together a workaround by not splitting the serialize method into load/save methods in the class affected for now, however I'm sure other people on this list will be able to suggest better solutions than mine.

And yes, I am including the list.hpp file incase anyone thinks I'm not including it.

Jason.
