<h2 class="chapter">9 Common problems</h2>
<p>This list is probably far too short. Feel free to suggest additional
questions (preferably with answers!)
<ul>
<li>Octave takes a long time to find symbols.
<p>Octave uses the <code>genpath</code> function to recursively add directories
to the list of directories searched for function files. Check the list
of directories with the <code>path</code> command. If the path list is very
long check your use of the <code>genpath</code> function.
<li>When plotting Octave occasionally gives me errors like ‘<samp><span class="samp">gnuplot> 9
0.735604 line 26317: invalid command</span></samp>’.
<p>There is a known bug in gnuplot 4.2 that can cause an off by one error
while piping data to gnuplot. It has been fixed in gnuplot 4.4.
<p>If you have obtained your copy of Octave from a distribution please file
a bug report requesting that the fix reported in the above bug report be
included.
<li>I cannot install a package. Octave complains about a missing
<code>mkoctfile</code>.
<p>Most distributions split Octave into several packages. The script
<code>mkoctfile</code> is then part of a separate package:
<ul>
<li>Debian/Ubuntu
<!-- This will work once we upload the Octave packages without a version -->
<!-- in their name to Debian. -->
<p><code>aptitude install octave-headers</code>
<li>Fedora
<p><code>yum install octave-devel</code>
</ul>
</ul>
