Boost
C++ Libraries
...one of the most highly
regarded and expertly designed C++ library projects in the
world.

This version of Boost is under active development. You are currently in the master branch. The current version is 1.91.0.
You shouldn't need to do anything special to configure Boost.Regex for use with your compiler - the Boost.Config subsystem should already take care of it, if you do have problems (or you are using a particularly obscure compiler or platform) then Boost.Config has a configure script that you can run.
