    <para>
       <application>SWIG</application> (Simplified Wrapper and Interface
       Generator) is a compiler that integrates <application>C</application>
       and <application>C++</application> with languages including
       <application>Perl</application>,
       <application>Python</application>,
       <application>Tcl</application>,

       <application>SWIG</application> can

       s-expressions and <application>XML</application>.

       <application>SWIG</application> reads annotated
       <application>C/C++</application> header files and creates wrapper
       code (glue code) in order to make the corresponding
       <application>C/C++</application> libraries available to the listed
       languages, or to extend <application>C/C++</application> programs
       with a scripting language.

    <title>Installation of SWIG</title>

    <para>
      Install <application>SWIG</application> by running the following
      commands:
    </para>

<screen><userinput>./configure --prefix=/usr                      \
            --without-javascript               \
            --without-maximum-compile-warnings &amp;&amp;
make</userinput></screen>

    <para>
      To test the results, issue: <command>PY3=1 make TCL_INCLUDE= -k check</command>.
      The unsetting of the variable <envar>TCL_INCLUDE</envar> is
      necessary since it is not correctly set by
      <emphasis>configure</emphasis>. The tests are only executed for the
      languages installed on your machine, so the disk space and SBU values
      given for the tests may vary, and should be considered as mere orders of
      magnitude. According to
      <application>SWIG</application>'s documentation, the failure of some
      tests should not be considered harmful. The go tests are buggy and may
      generate a lot of meaningless output.
    </para>

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

<screen role="root"><userinput>make install &amp;&amp;

  </sect2>

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

    <para>
      <parameter>--without-maximum-compile-warnings</parameter>: disables
      compiler ansi conformance enforcement, which triggers errors in
      the <application>Lua</application> headers (starting with Lua 5.3).
    </para>

    <para>
      <option>--without-&lt;language&gt;</option>: allows disabling the
      building of tests and examples for &lt;language&gt;, but all the
      languages capabilities of <application>SWIG</application> are always
      built. This switch is used for <application>JavaScript</application>
      because the SWIG implementation is incomplete and a lot of tests fail
      due to API changes in Node-20.
