Re: [Boost-users] [serialization]-- (corrected) serialize binarydata to a memory buffer?

try adding 

#include <boost/serialization/string.hpp>

  I have been having some issues trying to get this relatively simple binary memory based serialization to work.
  If I use a byte type below, I get errors with not finding a matching ctor:
  If I use a char, it compiles and thows an exception in   binary_iarchive_impl.hpp at line 52: 

            this->basic_binary_iarchive<Archive>::init();

  which appears to be related to char string processing.

  can anyone help me sort this out?

  thanks
  Rich

    You can use the Boost IOstreams library to create an iostream using a  memory buffer and use that with the binary archives
