Install Boost.Build
...................

Boost.Build_ is a text-based system for developing, testing, and
installing software. First, you'll need to build and
install it. To do this:

1. Go to the directory ``tools``\ |/|\ ``build``\ |/|\ ``v2``\ |/|.
2. Run |bootstrap|
3. Run ``b2 install --prefix=``\ *PREFIX* where *PREFIX* is
   the directory where you want Boost.Build to be installed
4. Add *PREFIX*\ |/|\ ``bin`` to your PATH environment variable.

Identify Your Toolset
.....................

First, find the toolset corresponding to your compiler in the
following table (an up-to-date list is always available `in the
Boost.Build documentation`__).

__ http://www.boost.org/boost-build2/doc/html/bbv2/reference/tools.html

.. Note:: If you previously chose a toolset for the purposes of
  `building b2`_, you should assume it won't work and instead
  choose newly from the table below.

__ Boost.Build_

If you have multiple versions of a particular compiler installed,
you can append the version number to the toolset name, preceded by
a hyphen, e.g. ``intel-9.0`` or
``borland-5.4.3``. |windows-version-name-caveat|


.. _build directory:
.. _build-directory:

Select a Build Directory
........................

Boost.Build_ will place all intermediate files it generates while
building into the **build directory**.  If your Boost root
directory is writable, this step isn't strictly necessary: by
default Boost.Build will create a ``bin.v2/`` subdirectory for that
purpose in your current working directory.

Invoke ``b2``
...............

.. |build-directory| replace:: *build-directory*
.. |toolset-name| replace:: *toolset-name*

Change your current directory to the Boost root directory and
invoke ``b2`` as follows:

.. parsed-literal::

  b2 **--build-dir=**\ |build-directory|_ **toolset=**\ |toolset-name|_ |build-type-complete| stage

For a complete description of these and other invocation options,
please see the `Boost.Build documentation`__.
