Thank you, George and Krzysztof. The reason I asked about this is that I’m getting an error when trying to implement serialize into my class, and I thought this was due to the serialize template only being in one of the serialization libraries, thinking they all had different functions. The error I get is:
 
C:/boost_1_54_0/boost/serialization/access.hpp:118: undefined reference to `void boinc::work::Sudoku::serialize<boost::archive::binary_oarchive>(boost::archive::binary_oarchive&, unsigned int)'
 
Googling the error, I found this link:
 
http://stackoverflow.com/questions/9795888/boost-serialization-using-separate-h-and-cpp-files
 
Which mentions putting the definition into the header, which I’ve tried, but I still get the same error. So given the following code, can anyone tell me what I’m doing wrong?
 
#ifndef SUDOKU_HPP_
#define SUDOKU_HPP_
 
#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>
 
namespace boinc {
    class Sudoku {
        friend class boost::serialization::access;
 
        private:
            template<class Archive> void serialize(Archive &ar, const unsigned int version) {
                ...
            }
        };
    }
}
#endif
 
I have been following the serialization tutorial here:
 
http://www.boost.org/doc/libs/1_54_0/libs/serialization/doc/tutorial.html
 
And I don’t see any difference between my code and the code in the documentation, besides the archive inclusions.

Subject: Re: [Boost-users] How to choose which library version to choose?
 
2013/10/9 Michael Kragh Pedersen <m_kragh_pedersen@hotmail.com>
I have downloaded and built the Boost library, as according to these instructions:
 
 
I need to use the serialization library, so I looked at the stage\lib folder, only to 16 different library files! Some are named mt, some sd, some s or d, and some a combination thereof, all this following libboost_serialization-mgw48. Some are dll files and some are a files.
 
Those are different variants of the same library; you should choose one variant, and link to that variant only.
 
-mt means multithreading
-s means static (I think)
-d means debug
-sd probably means static debug
 
I tried using –lboost_serialization, as I have seen this mentioned on a lot of forums, but Eclipse says it can’t find that library. So how on Earth am I supposed to figure out which of the many files to link to?!
 
If you want the static single-threading non-debug version, you probably need something like -lboost_serialization-s-mgw48 -LX:\path\to\boost\libs
 
HTH,
Kris
