Boost thread are not a template only library. You need to add a -lboost_thread while linking /compiling.

Most of the libraries in boost are implemented in headers. They can simply be included like you have done. Boost thread on the other hand, is of such a nature that you need to depend on its compiled units, only the declaration of its function are readily available to you in the header. So the compiler, or more correctly the linker, which is responsible for linking your calls to the declared functions /classes need to know where to look for these symbols. By invoking the compiler with a -lboost_thread you tell it to link to the library (-l) boost thread.
