[Boost-users] How to choose which library version to choose?

I have downloaded and built the Boost library, as according to these instructions: http://theseekersquill.wordpress.com/2010/08/24/howto-boost-mingw/ 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. 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?!
