BOOST libraries in multithreading-aware mode

Because you did not specify how you have built, and on what platform, I’ll explain the whole story. Both on Linux and Windows, Boost.Thread library is built in MT mode. On Windows, by default, you get -mt suffix for it. On Linux, by default in 1.42, you get no suffix. The reason you get no suffix on Linux is that pretty much no other library uses such convention, and it’s much less important on Linux anyway.

Does this clarify things?

There is an option to put “-mt” suffix back (bjam --layout=tagged)

--layout=<layout>     Determines whether to choose library names
                      and header locations such that multiple
                      versions of Boost or multiple compilers can
                      be used on the same system.

                          versioned - Names of boost binaries
                          include the Boost version number, name and
                          version of the compiler and encoded build
                          properties.  Boost headers are installed in a
                          subdirectory of <HDRDIR> whose name contains
                          the Boost version number.

                          tagged -- Names of boost binaries include the
                          encoded build properties such as variant and
                          threading, but do not including compiler name
                          and version, or Boost version. This option is
                          useful if you build several variants of Boost,
                          using the same compiler.

                          system - Binaries names do not include the
                          Boost version number or the name and version
                          number of the compiler.  Boost headers are
                          installed directly into <HDRDIR>.  This option
                          is intended for system integrators who are
                          building distribution packages.

                      The default value is 'versioned' on Windows, and
                      'system' on Unix.
