Boost.Build will place the Boost binaries in the ``stage``\ |/|
subdirectory of your `build directory`_.

.. Note:: ``bjam`` is case-sensitive; it is important that all the
   parts shown in **bold** type above be entirely lower-case.

For a description of other options you can pass when invoking
``bjam``, type::

  bjam --help

In particular, to limit the amount of time spent building, you may
be interested in:

* reviewing the list of library names with ``--show-libraries``
* limiting which libraries get built with the ``--with-``\
  *library-name* or ``--without-``\ *library-name* options
* choosing a specific build variant by adding ``release`` or
  ``debug`` to the command line.

Expected Build Output
---------------------

During the process of building Boost libraries, you can expect to
see some messages printed on the console.  These may include

* Notices about Boost library configuration—for example, the Regex
  library outputs a message about ICU when built without Unicode
  support, and the Python library may be skipped without error (but
  with a notice) if you don't have Python installed.

* Messages from the build tool that report the number of targets
  that were built or skipped.  Don't be surprised if those numbers
  don't make any sense to you; there are many targets per library.

* Build action messages describing what the tool is doing, which
  look something like:

  .. parsed-literal::

    *toolset-name*.c++ *long*\ /\ *path*\ /\ *to*\ /\ *file*\ /\ *being*\ /\ *built*

* Compiler warnings.

In Case of Build Errors
-----------------------

The only error messages you see when building Boost—if any—should
be related to the IOStreams library's support of zip and bzip2
formats as described here__.  Install the relevant development
packages for libz and libbz2 if you need those features.  Other
errors when building Boost libraries are cause for concern.

If it seems like the build system can't find your compiler and/or
linker, consider setting up a ``user-config.jam`` file as described
in the `Boost.Build documentation`_.  If that isn't your problem or
the ``user-config.jam`` file doesn't work for you, please address
questions about configuring Boost for your compiler to the
`Boost.Build mailing list`_.
