    <title>Installation of Boost</title>

    <para>
      A change in this version of <application>boost</application> breaks
      the few packages which use the <application>phoenix</application>
      module when compiled with current <application>GCC</application>. In BLFS,
      that affects <xref linkend="libreoffice"/>. Fix this with the following
      command:
    </para>

<screen><userinput>sed -i '/#include.*phoenix.*tuple.hpp.*/d' \
  boost/phoenix/stl.hpp</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 --with-python=python3 &amp;&amp;
./b2 stage -j<replaceable>&lt;N&gt;</replaceable> threading=multi link=shared</userinput></screen>

    <para>
      To run Boost.Build's regression tests, issue
      <command>pushd tools/build/test; python3 test_all.py; popd</command>.
      <!--With python-3.10.x all 168 tests should pass.  With
      <xref linkend='python3'/>, 20 tests fail for undetermined reasons.-->
      <!-- This was fixed in 1.83.0 -->
    </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>

    <note>
      <para>
        Boost installs many versioned directories in /usr/lib/cmake.
        If a new version of <application>Boost</application> is installed over a
        previous version, the older cmake directories need to be
        explicitly removed.  To do this, run as the
        <systemitem class="username">root</systemitem> user:
      </para>

<screen role="root"><userinput>rm -rf /usr/lib/cmake/[Bb]oost*</userinput></screen>

      <para>
        before installing the new version.
      </para>
    </note>

    <para>
      Now, as the <systemitem class="username">root</systemitem> user:
    </para>

<!-- dev note: ./b2 - -prefix=<DESTDIR>/usr install threading=multi link=shared -->

<screen role="root"><userinput>./b2 install threading=multi link=shared</userinput></screen>

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

    <para>
      <parameter>sed -i '/#include ...</parameter>: This removes the inclusion
      of <filename>boost/phoenix/stl/tuple.hpp</filename> from this header-only
      library, allowing applications which use it to link using recent C++.
      <!-- FIXME: remove before 11.3 is we still use 1.81.0 and LO-7.4,
      this alternative is only for people working through the development book.-->
      An alternative is to edit
      <filename>/usr/include/boost/phoenix/stl.hpp</filename> if this version of
      boost has already been installed without this <command>sed</command>.
    </para>

    <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>--with-python=python3</parameter>: This switch ensures Python3
      is used if Python2 is installed.
    </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.
