[boost] Boost bit_integer library

hi! I am trying to use the boost::big_integer library. I include the line #include "boost/big_integer.hpp" in a toy program (as I have with the others) but it generated hundreds of lines of linker-error messages. I have boost (path) set up properly and have dumped the relevant files / folders into the boost and libs folders accordingly.... what am I doing wrong? Thanks for your help in advance Matt
