[Boost-users] [Serialization] Compile error in load_wrapper

Subject: [Boost-users] [Serialization] Compile error in load_wrapper

Hi,  I am having trouble serializing a class.  Actually, I am having
trouble compiling the class as below.  The actual archiving is behind an
interface (hence the Save and Load methods) which may work (once I get
this sorted, I'm going to look at the export traits), but the error
points to me not declaring the is_wrapper properly.

 

My class:

 

BOOST_CLASS_IS_WRAPPER(Frame);

 

class Frame

{

...

 

// Serialize interface

uint32 Save( uint8* pStream )

{

    ostrstream os( (char*)pStream, STREAM_SIZE );

    boost::archive::text_oarchive oa(os);

    oa << this;

    return os.pcount();

}

void Load( uint8* pStream )

{

    istrstream is( (char*)pStream, STREAM_SIZE );

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

    ia >> this;

}

 

friend class boost::serialization::access;

template< class Archive >

void serialize( Archive& ar, const unsigned int version )

{

    string strObjectType = "IFrame";

    ar << strObjectType.length() << strObjectType;

    ar << m_lMaxFrameLength << m_lDataLength << m_uiTimeStamp;

    ar << boost::serialization::make_binary_object( (void*)(this + 1),
m_lMaxFrameLength );

}

 

My error:

 

W:\NewFramework\Boost\boost/archive/detail/iserializer.hpp(541) : error
