Re: [Boost-users] Serialization of pointers with custom allocators

      Looking at this I might make one more small adjustment:

try something like the following:

class _IplImage {
public:
   friend boost::serialization::access;
   int roi, width, height, depth, nChannels;
   int imageSize;
   int * imageData;
   template<class Archive>
   void save(Archive & ar, const unsigned int version) const {
       ar << roi << width << height << depth << nChannels;
       ar << imageSize;
       ar << boost::serialization::binary_object(imageData,
   imageSize); }
   template<class Archive>
   void load(Archive & ar, const unsigned int version){
       ar >> roi >> width >> height >> depth >> nChannels;
       ar >> imageSize;
         imageData = CreateImageData(roi, width, height, depth, nChannels, 
imageSize);
       ar >> boost::serialization::binary_object(imageData,
   imageSize); }
   BOOST_SERIALIZATION_SPLIT_MEMBER()
};
main(int argc, char *argv[]){
   const _IplImage i;
   {
       std::ofstream os("test");
       boost::archive::text_oarchive oa(os);
       oa << i;
   }
   _IplImage new_i;
   {
       std::ifstream is("test");
       boost::archive::text_iarchive ia(is);
       ia >> new_i;
   }
   // compare the new and old images
}
This compiles w/o issue on my system.
