      <application>Boost</application> provides a set of free peer-reviewed
      portable C++ source libraries. It includes libraries for linear algebra,

      First, fix a bug with the header files path, when Python3 is used:
    </para>

<screen><userinput>sed -e '/using python/ s@;@: /usr/include/python${PYTHON_VERSION/3*/${PYTHON_VERSION}m} ;@' \
    -i bootstrap.sh</userinput></screen>
-->
    <para>
      This package can be built with several jobs running in parallel. In
      the instructions below, <parameter>&lt;N&gt;</parameter> stands for the
      number of jobs. Install <application>Boost</application> by running the
      following commands:
    </para>


<screen><userinput>./bootstrap.sh --prefix=/usr &amp;&amp;
./b2 stage -j<replaceable>&lt;N&gt;</replaceable> threading=multi link=shared</userinput></screen>

    <para>
      To run the Boost.Build's regression test, <xref linkend="python2"/>
      is required.
      Run the tests with: issue <command>pushd tools/build/test; 
      python3 test_all.py; popd</command>. 
      All 152 tests should pass.
    </para>

    <para>
      To run every library's regression tests, issue <command>pushd status;
      ../b2; popd</command>.  A few tests may fail. They take a very long time
      (over 119 SBU at -j4) and use a very large amount of disk space
      (46 GB). You should use the <parameter>-jN</parameter> switch to
      speed them up.
    </para>

  <sect2 role="commands">
    <title>Command Explanations</title>

    <para>
      <parameter>threading=multi</parameter>: This parameter ensures that
      <application>Boost</application> is built with multithreading support.
    </para>

    <para>
      <parameter>link=shared</parameter>: This parameter ensures that only
      shared libraries are created, except for libboost_exception and
      libboost_test_exec_monitor which are created as static. Most people
      will not need the static libraries, and most programs using
      <application>Boost</application> only use the headers. Omit
      this parameter if you do need static libraries.
    </para>

    <para>
      <parameter>ln -svf detail/sha1.hpp ...</parameter>: The
      <filename>uuid/sha1.hpp</filename> used to be a regular header, but by
      boost_1_66_0 it had been changed to load the similar
      <filename>detail/sha1.hpp</filename> header, with a message that it had
      been deprecated. It has now been removed, but not every package which uses
      it has been changed. An example is one of the libraries downloaded as a
      git version by libreoffice. The symlink enables this and similar packages
      to build.
    </para>

    <para>
       <option>-jN</option>: This switch may be added to the
       <command>b2</command> command lines, to run up to N processes in
       parallel.
    </para>

    <para>
      <option>--with-python=python3</option>: Add this switch to the <command>
      bootstrap</command> command, if you want Boost
      to use Python3 instead of Python2.  Using Python3 is known to cause the
      installation to fail on some systems.
