       <application>SWIG</application> (Simplified Wrapper and Interface
       Generator) is a compiler that integrates <application>C</application>

       <application>Perl</application>, <application>Python</application>,
       <application>Tcl</application>, <application>Ruby</application>,

       <application>Common Lisp</application>, and

       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>

<!-- Spaces are significant in <screen> sections -->
<screen><userinput>./configure --prefix=/usr                      \
            --without-clisp                    \
            --without-maximum-compile-warnings &amp;&amp;
make</userinput></screen>

    <para>
      To test the results, issue:
      <command>make -k check TCL_INCLUDE= GOGCC=true</command>. The (un)setting
      of the two variables <envar>GOGCC</envar> and <envar>TCL_INCLUDE</envar>
      is necessary, since they are 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. If you have both <xref linkend="python2"/> and
      <xref linkend="python3"/> installed, the Python-3 tests are not run.
      You can run tests for Python-3 by issuing
      <command>PY3=1 make check-python-examples</command> followed by
      <command>PY3=1 make check-python-test-suite</command>.  According to
      <application>SWIG</application>'s documentation, the failure of some
      tests should not be considered harmful.

  <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. We use it for <application>Clisp</application>, because the
      SWIG implementation is very incomplete and a lot of tests fail.
