Hi all

I have some trouble with the serialization of objects in C++ using boost. Since there was some strange behaviour in the code, I tried to serialize and deserialize a sample object isolated trying two versions:

deSerialize(Packet p1, Packet p2){    // Version 1 using
      stringstreams

          std::ostringstream *serialized = new std::ostringstream[2];

   
      serialized[0]=std::ostringstream(std::ios_base::binary);

   
      serialized[1]=std::ostringstream(std::ios_base::binary);

boost::archive::text_oarchive oa(serialized[0]);

oa << p1;

boost::archive::text_oarchive oa2(serialized[1]);

oa2 << p2;

std::string s1, s2;

s1 = serialized[0].str();

s2 = serialized[1].str();

     //deserialize

          CCNDataPkt newPacket;

          std::istringstream inputStream(s2, std::ios_base::binary);

          boost::archive::text_iarchive ia(inputStream);

    ia >> newPacket; // throws boost::archive::archive_exception: invalid signature.

and

deSerialize(Packet p1, Packet p2){    // Version 2 using
      ofstreams

std::ofstream
      of("deleteme",std::ios_base::binary);

boost::archive::binary_oarchive oa(of);

oa << p1;

    std::ifstream ifstr("deleteme",
      std::ios_base::binary);

CCNDataPkt newp;

boost::archive::binary_iarchive ia(ifstr);

    ia >> newp;    // boost::archive::archive_exception: invalid signature.

However, both variants returned an invalid signature exception even though I haven't changed anything on the serialized data. Does anyone know what is wrong in either of the examples above? The methods for serializing the custom object 'Packet' are implemented according to the boost serialization tutorial (non-intrusive version splitted)

Any hints are very much appreciated - TIA!

Cheers,
Alex
