Some Boost library consists of both headers and source files. These source 
files are usually compiled into a library, which you need to link with. 
 From the error message I would think that you need to link to Boost.System 
and Boost.Filesystem.

Those libraries should have been provided upon installation of Boost. If 
not, you'll need to figure out how to build them for yourself, or just 
include the corresponding sources into your project.
