Comment (by viboes):

 If you don't want to use the time related functions based on Boost.Chrono
 you can define BOOST_THREAD_DONT_USE_CHRONO. From Boost.Thread
 documentation:


 {{{
 Boost.Chrono

 Boost.Thread uses by default Boost.Chrono for the time related functions
 and define BOOST_THREAD_USES_CHRONO if BOOST_THREAD_DONT_USE_CHRONO is not
 defined. The user should define BOOST_THREAD_DONT_USE_CHRONO for compilers
 that don't work well with Boost.Chrono.
 }}}


 Otherwise you need to link with it, or define the macros needed to make
 Boost.Chrono header only. From Boost.Chrono documentation:


 {{{
 Building Boost.Chrono

 Boost.Chrono can be configured as a header-only library defining
 BOOST_CHRONO_HEADER_ONLY. However Boost.Chrono depends on the non header-
 only library Boost.System, so that you will need to link with
 boost_system.

 Boost.System has un undocumented feature (use of macro
 BOOST_ERROR_CODE_HEADER_ONLY) to make it header only, but it is buggy (see
 #7347 duplicate symbol while BOOST_ERROR_CODE_HEADER_ONLY is defined)

 If BOOST_CHRONO_HEADER_ONLY is not defined you need to compile it and
 build the library before use, for example using:

 bjam libs/chrono/build

 }}}
