...one of the most highly regarded and expertly designed C++ library projects in the world. Herb Sutter and Andrei Alexandrescu , C++ Coding Standards

Boost.Thread is configured following the conventions used to build libraries with separate source code . Boost.Thread will import/export the code only if the user has specifically asked for it, by defining either BOOST_ALL_DYN_LINK if they want all boost libraries to be dynamically linked, or BOOST_THREAD_DYN_LINK if they want just this one to be dynamically liked. The definition of these macros determines whether BOOST_THREAD_USE_DLL is defined. If BOOST_THREAD_USE_DLL is not defined, the library will define BOOST_THREAD_USE_DLL or BOOST_THREAD_USE_LIB depending on whether the platform. On non windows platforms BOOST_THREAD_USE_LIB is defined if is not defined. In windows platforms, BOOST_THREAD_USE_LIB is defined if BOOST_THREAD_USE_DLL and the compiler supports auto-tss cleanup with Boost.Threads (for the time been Msvc and Intel) The source code compiled when building the library defines a macros BOOST_THREAD_SOURCE that is used to import or export it. The user must not define this macro in any case. Boost.Thread depends on some non header-only libraries. Boost.System: This dependency is mandatory and you will need to link with the library. Boost.Chrono: This dependency is optional (see below how to configure) and you will need to link with the library if you use some of the time related interfaces. Boost.DateTime: This dependency is mandatory, but even if Boost.DateTime is a non header-only library Boost.Thread uses only parts that are header-only, so in principle you should not need to link with the library. It seems that there are some IDE (as e.g. Visual Studio) that deduce the libraries that a program needs to link to inspecting the sources. Such IDE could force to link to Boost.DateTime and/or Boost.Chrono. As the single mandatory dependency is to Boost.System, the following
bjam toolset=msvc-11.0 --build-type=complete --with-thread
      will install only boost_thread and boost_system.
      Users of such IDE should force the Boost.Chrono and Boost.DateTime build using
bjam toolset=msvc-11.0 --build-type=complete --with-thread --with-chrono --with-date_time
      The following section describes all the macros used to configure Boost.Thread.

Table 38.1. Default Values for Configurable Features

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. Boost.Thread uses by default an internal move semantic implementation. Since version 3.0.0 you can use the move emulation emulation provided by Boost.Move. When BOOST_THREAD_VERSION==2 define BOOST_THREAD_USES_MOVE if you want to use Boost.Move interface. When BOOST_THREAD_VERSION>=3 define BOOST_THREAD_DONT_USE_MOVE if you don't want to use Boost.Move interface. The Boost.DateTime time related functions introduced in Boost 1.35.0, using the
Boost.Date_Time library are deprecated. These include (but are not limited to): boost::this_thread::sleep() timed_join() timed_wait() timed_lock() When BOOST_THREAD_VERSION<=3 && defined BOOST_THREAD_PLATFORM_PTHREAD define BOOST_THREAD_DONT_USE_DATETIME if you don't want to use Boost.DateTime related interfaces. When BOOST_THREAD_VERSION>3 && defined BOOST_THREAD_PLATFORM_PTHREAD define BOOST_THREAD_USES_DATETIME if you want to use Boost.DateTime related interfaces. Define BOOST_THREAD_USES_ATOMIC if you want to use Boost.Atomic. Define BOOST_THREAD_DONT_USE_ATOMIC if you don't want to use Boost.Atomic or if it is not supported in your platform. When BOOST_THREAD_PROVIDES_THREAD_EQ is defined Boost.Thread provides these deprecated feature. Use instead boost::thread::id::operator== boost::thread::id::operator!= When BOOST_THREAD_VERSION>=4 define BOOST_THREAD_PROVIDES_THREAD_EQ if you want this feature. When BOOST_THREAD_VERSION<4 define BOOST_THREAD_DONT_PROVIDE_THREAD_EQ if you don't want this feature. boost::condition is deprecated. When BOOST_THREAD_PROVIDES_CONDITION is defined Boost.Thread provides this deprecated feature. Use instead boost::condition_variable_any. When BOOST_THREAD_VERSION>3 define BOOST_THREAD_PROVIDES_CONDITION if you want this feature. When BOOST_THREAD_VERSION<=3 define BOOST_THREAD_DONT_PROVIDE_CONDITION if you don't want this feature. When BOOST_THREAD_PROVIDES_NESTED_LOCKS is defined Boost.Thread provides these deprecated feature. Use instead * boost::unique_lock<boost::mutex>, * boost::unique_lock<boost::mutex> with the try_to_lock_t constructor, * boost::unique_lock<boost::timed_mutex> * boost::unique_lock<boost::timed_mutex> with the try_to_lock_t constructor * boost::unique_lock<boost::timed_mutex> * boost::unique_lock<boost::recursive_mutex>, * boost::unique_lock<boost::recursive_mutex> with the try_to_lock_t constructor, * boost::unique_lock<boost::recursive_timed_mutex> * boost::unique_lock<boost::recursive_timed_mutex> with the try_to_lock_t constructor * boost::unique_lock<boost::recursive_timed_mutex> When BOOST_THREAD_VERSION>=4 define BOOST_THREAD_PROVIDES_NESTED_LOCKS if you want these features. When BOOST_THREAD_VERSION<4 define BOOST_THREAD_DONT_PROVIDE_NESTED_LOCKS if you don't want thes features. Boost.Thread uses by default a thread::id on Posix based on the pthread type (BOOST_THREAD_PROVIDES_BASIC_THREAD_ID). For backward compatibility and also for compilers that don't work well with this modification the user can define BOOST_THREAD_DONT_PROVIDE_BASIC_THREAD_ID. Define BOOST_THREAD_DONT_PROVIDE_BASIC_THREAD_ID if you don't want these features. The shared mutex implementation on Windows platform provides currently less functionality than the generic one that is used for PTheads based platforms. In order to have access to these functions, the user needs to define BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN to use the generic implementation, that while could be less efficient, provides all the functions. When BOOST_THREAD_VERSION==2 define BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN if you want these features. When BOOST_THREAD_VERSION>=3 define BOOST_THREAD_DONT_PROVIDE_GENERIC_SHARED_MUTEX_ON_WIN if you don't want these features. Boost.Threads includes in version 3 the Shared Locking Upwards Conversion as defined in Shared Locking. These conversions need to be used carefully to avoid deadlock or livelock. The user need to define explicitly BOOST_THREAD_PROVIDES_SHARED_MUTEX_UPWARDS_CONVERSIONS to get these upwards conversions. When BOOST_THREAD_VERSION==2 define BOOST_THREAD_PROVIDES_SHARED_MUTEX_UPWARDS_CONVERSIONS if you want these features. When BOOST_THREAD_VERSION>=3 define BOOST_THREAD_DONT_PROVIDE_SHARED_MUTEX_UPWARDS_CONVERSION if you don't want these features. In Shared Locking the lock conversions are explicit. As this explicit conversion breaks the lock interfaces, it is provided only if the BOOST_THREAD_PROVIDES_EXPLICIT_LOCK_CONVERSION is defined. When BOOST_THREAD_VERSION==2 define BOOST_THREAD_PROVIDES_EXPLICIT_LOCK_CONVERSION if you want these features. When BOOST_THREAD_VERSION==3 define BOOST_THREAD_DONT_PROVIDE_EXPLICIT_LOCK_CONVERSION if you don't want these features. C++11 uses std::future. Versions of Boost.Thread previous to version 3.0.0 uses boost:unique_future. Since version 3.0.0 boost::future replaces boost::unique_future when BOOST_THREAD_PROVIDES_FUTURE is defined. The documentation doesn't contains anymore however boost::unique_future. When BOOST_THREAD_VERSION==2 define BOOST_THREAD_PROVIDES_FUTURE if you want to use boost::future. When BOOST_THREAD_VERSION>=3 define BOOST_THREAD_DONT_PROVIDE_FUTURE if you want to use boost::unique_future. C++11 promise initialize the associated state at construction time. Versions of Boost.Thread previous to version 3.0.0 initialize it lazily at any point in time in which this associated state is needed. Since version 3.0.0 this difference in behavior can be configured. When BOOST_THREAD_PROVIDES_PROMISE_LAZY is defined the backward compatible behavior is provided. When BOOST_THREAD_VERSION==2 define BOOST_THREAD_DONT_PROVIDE_PROMISE_LAZY if you want to use boost::future. When BOOST_THREAD_VERSION>=3 define BOOST_THREAD_PROVIDES_PROMISE_LAZY if you want to use boost::unique_future. // ... template <class R, class Alloc> struct uses_allocator<promise<R>,Alloc>: true_type {}; where
struct allocator_arg_t { };
constexpr allocator_arg_t allocator_arg = allocator_arg_t();
template <class T, class Alloc> struct uses_allocator;
          Since version 3.0.0 Boost.Thread implements this constructor using the
          following interface
namespace boost
  typedef container::allocator_arg_t allocator_arg_t;
  constexpr allocator_arg_t allocator_arg = {};
  namespace container
    template <class R, class Alloc>
    struct uses_allocator<promise<R>,Alloc>: true_type {};
  template <class T, class Alloc>
  struct uses_allocator : public container::uses_allocator<T, Alloc> {};
          which introduces a dependency on Boost.Container. This feature is provided
          only if BOOST_THREAD_PROVIDES_FUTURE_CTOR_ALLOCATORS
          is defined.
          When BOOST_THREAD_VERSION==2 define
          BOOST_THREAD_PROVIDES_FUTURE_CTOR_ALLOCATORS
           if you want these features. When BOOST_THREAD_VERSION>=3 define
          BOOST_THREAD_DONT_PROVIDE_FUTURE_CTOR_ALLOCATORS
           if you don't want these features.
          C++11 has a different semantic for the thread destructor and the move assignment.
          Instead of detaching the thread, calls to terminate() if the thread was
          joinable. When BOOST_THREAD_PROVIDES_THREAD_DESTRUCTOR_CALLS_TERMINATE_IF_JOINABLE
          and BOOST_THREAD_PROVIDES_THREAD_MOVE_ASSIGN_CALLS_TERMINATE_IF_JOINABLE
          is defined Boost.Thread provides the C++ semantic.
          When BOOST_THREAD_VERSION==2 define
          BOOST_THREAD_PROVIDES_THREAD_DESTRUCTOR_CALLS_TERMINATE_IF_JOINABLE
           if you want these features. When BOOST_THREAD_VERSION>=3 define
          BOOST_THREAD_DONT_PROVIDE_THREAD_DESTRUCTOR_CALLS_TERMINATE_IF_JOINABLE
           if you don't want these features.
          When BOOST_THREAD_VERSION==2 define
          BOOST_THREAD_PROVIDES_THREAD_MOVE_ASSIGN_CALLS_TERMINATE_IF_JOINABLE
           if you want these features. When BOOST_THREAD_VERSION>=3 define
          BOOST_THREAD_DONT_PROVIDE_THREAD_MOVE_ASSIGN_CALLS_TERMINATE_IF_JOINABLE
           if you don't want these features.
          C++11 defines a default constructor for once_flag. When BOOST_THREAD_PROVIDES_ONCE_CXX11
           is defined Boost.Thread provides this C++ semantics. In this case,
          the previous aggregate syntax is not supported.
boost::once_flag once = BOOST_ONCE_INIT;
          You should now just do
boost::once_flag once;
          When BOOST_THREAD_VERSION==2 define
          BOOST_THREAD_PROVIDES_ONCE_CXX11
          if you want these features. When BOOST_THREAD_VERSION>=3 define
          BOOST_THREAD_DONT_PROVIDE_ONCE_CXX11
          if you don't want these features.
          C++11 packaged task class has a Signature template parameter. When BOOST_THREAD_PROVIDES_SIGNATURE_PACKAGED_TASK
           is defined Boost.Thread provides this C++ feature.
          When BOOST_THREAD_VERSION<4 define
          BOOST_THREAD_PROVIDES_SIGNATURE_PACKAGED_TASK
          if you want this feature. When BOOST_THREAD_VERSION>=4 define
          BOOST_THREAD_DONT_PROVIDE_SIGNATURE_PACKAGED_TASK
          if you don't want this feature.
          C++11 thread constructor accept a variable number of rvalue arguments has.
          When BOOST_THREAD_PROVIDES_VARIADIC_THREAD
           is defined Boost.Thread provides this C++ feature if the following
          are not defined
              BOOST_NO_SFINAE_EXPR
              BOOST_NO_CXX11_VARIADIC_TEMPLATES
              BOOST_NO_CXX11_DECLTYPE
              BOOST_NO_CXX11_DECLTYPE_N3276
              BOOST_NO_CXX11_RVALUE_REFERENCES
              BOOST_NO_CXX11_TRAILING_RESULT_TYPES
              BOOST_NO_CXX11_RVALUE_REFERENCES
              BOOST_NO_CXX11_HDR_TUPLE
          When BOOST_THREAD_VERSION>4 define
          BOOST_THREAD_DONT_PROVIDE_VARIADIC_THREAD
           if you don't want this feature.
          C++11 future<>::get() invalidates the future once its value has been
          obtained. When BOOST_THREAD_PROVIDES_FUTURE_INVALID_AFTER_GET
           is defined Boost.Thread provides this C++ feature.
          When BOOST_THREAD_VERSION<4 define
          BOOST_THREAD_PROVIDES_FUTURE_INVALID_AFTER_GET
          if you want this feature. When BOOST_THREAD_VERSION>=4 define
          BOOST_THREAD_DONT_PROVIDE_FUTURE_INVALID_AFTER_GET
          if you don't want this feature.
          Thread interruption, while useful, makes any interruption point less efficient
          than if the thread were not interruptible.
          When BOOST_THREAD_PROVIDES_INTERRUPTIONS
          is defined Boost.Thread provides interruptions. When BOOST_THREAD_DONT_PROVIDE_INTERRUPTIONS
          is defined Boost.Thread don't provide interruption.
          Boost.Thread defines BOOST_THREAD_PROVIDES_INTERRUPTIONS if neither BOOST_THREAD_PROVIDES_INTERRUPTIONS
          nor BOOST_THREAD_DONT_PROVIDE_INTERRUPTIONS are defined, so that there
          is no compatibility break.
          BOOST_THREAD_VERSION defines
          the Boost.Thread version. The default version is 2. In this case the following
          breaking or extending macros are defined if the opposite is not requested:
              BOOST_THREAD_PROVIDES_PROMISE_LAZY
          The user can request the version 3 by defining BOOST_THREAD_VERSION
          to 3. In this case the following breaking or extending macros are defined
          if the opposite is not requested:
              Breaking change BOOST_THREAD_PROVIDES_EXPLICIT_LOCK_CONVERSION
              Conformity & Breaking change BOOST_THREAD_PROVIDES_FUTURE
              Uniformity BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN

          The user can request the version 4 by defining BOOST_THREAD_VERSION
          to 4. In this case the following breaking or extending macros are defined
          if the opposite is not requested:
              Conformity & Breaking change BOOST_THREAD_PROVIDES_SIGNATURE_PACKAGED_TASK
