Boost.Build_ is a text-based system for developing, testing, and
installing software.  To use it, you'll need an executable called
``bjam``.

.. |precompiled-bjam| replace:: download a pre-built ``bjam`` executable


.. _precompiled-bjam: http://sourceforge.net/project/showfiles.php?group_id=7586&package_id=72941

.. _Boost.Build: ../../tools/build/index.html
.. _Boost.Jam: ../../tools/build/v2/engine/index.html
.. _Boost.Build documentation: Boost.Build_

Get ``bjam``
............

``bjam`` is the |command-line tool| that drives the Boost Build
system.  To build Boost binaries, you'll invoke ``bjam`` from the
Boost root.  

We suggest you |precompiled-bjam|_ for your platform.
Alternatively, you can build ``bjam`` yourself using `these
instructions`__.

__ `building bjam`_

Move the ``bjam`` executable into a directory in your PATH.  You can
see the list of directories in your PATH, separated by |pathsep|\ s,
by typing “\ |path|\ ” at the command prompt.

.. _toolset:
.. _toolset-name:

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 bjam`_, 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 ``bjam``
...............

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

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

.. parsed-literal::

  bjam **--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`__.
