Most Boost libraries are **header-only**: they consist *entirely  of header files* containing templates and inline functions, and  require no separately-compiled library binaries or special  treatment when linking... .. _separate: The only Boost libraries that *must* be built separately are:* Boost.Filesystem_* Boost.IOStreams_* Boost.ProgramOptions_* Boost.Python_ (see the `Boost.Python build documentation`__  before building and installing it)* Boost.Regex_* Boost.Serialization_* Boost.Signals_* Boost.Thread_* Boost.Wave___ ../../libs/python/doc/building.htmlA few libraries have optional separately-compiled binaries:* Boost.DateTime_ has a binary component that is only needed if  you're using its ``to_string``\ /\ ``from_string`` or serialization  features, or if you're targeting Visual C++ 6.x or Borland.* Boost.Graph_ also has a binary component that is only needed if  you intend to `parse GraphViz files`__.* Boost.Test_ can be used in “header-only” or “separately compiled”  mode, although **separate compilation is recommended for serious  use**.__ ../../libs/graph/doc/read_graphviz.html
