<h3 class="subsection">D.8.4 Additional <code>harminv</code> notes</h3>

<p>The <code>harminv</code> library interface requires the <code>harminv</code> and
<code>lapack</code> libraries to be installed on the host system, and also
requires standard complex number support from the system&rsquo;s C library.
</p>
<p>The author&rsquo;s installation of <code>avram</code> has been compiled against
the Debian <code>harminv</code> development library package, which at this
writing is unmaintained and is missing the necessary header file
&lsquo;<tt>harminv-int.h</tt>&rsquo;, without which compilation of files including
&lsquo;<tt>harminv.h</tt>&rsquo; fails. Some headers from &lsquo;<tt>harminv.h</tt>&rsquo; have been
copied directly into &lsquo;<tt>avram-x.x.x/src/harminv.c</tt>&rsquo; under the
<code>avram</code> source tree to avoid this dependence, so that
<code>avram</code> will compile correctly on a Debian system. These may need
to be updated if necessary to track the <code>harminv</code> source.
