You need to download the C++ Boost libraries and link them with your compiler. Latest download and documentation of it can be found here http://www.boost.org/users/history/version_1_61_0.html - Afaik Trinity wiki should go throuhgt his as well, perhaps they don't? It may be a lot of text and sound tricky but it's easy installing, give it a shot and you'll have it within an hour or two (compiling it takes some time).
