<h3 class="subsection">1.6.6 Configuration Related Errors</h3>

<p>The source code distribution of <code>avram</code> incorporates a flexible
configuration script allowing it to be installed on a variety of
platforms. Not all platforms allow support for all features. It is also
anticipated that new features may be added to <code>avram</code> from time to
time. Some problems may therefore occur due to features not being
supported at your site for either of these reasons. The following error
messages are relevant to these situations.
</p>
<dl compact="compact">
<dt> <code>unsupported hook</code></dt>
<dd><a name="index-unsupported-hook-1"></a>
<p>If it&rsquo;s not simply due to an application programming error
(<a href="Application-Programming-Errors.html#Application-Programming-Errors">Application Programming Errors</a>) this message may be the result of
trying to use an application that requires a newer version of
<code>avram</code> than the one installed, even though applications should
avoid this problem by checking the version number at run time. If this
is the reason, the solution would be to install the latest version.
</p></dd>
<dt> <code><var>application-name</var>: I need avram linked with <var>foo</var>, <var>bar</var> and <var>baz</var>.</code></dt>
<dd><a name="index-I-need-avram-linked-with"></a>
<p>A message of the this form indicates that a new installation may be
needed. At this writing (11/11/1), <code>avram</code> may report this message
with respect to <code>libexpect5.32</code>, <code>tcl8.3</code>, and <code>libutil</code>
if any of the &lsquo;<samp>-i</samp>&rsquo;, &lsquo;<samp>-t</samp>&rsquo;, or &lsquo;<samp>-s</samp>&rsquo; options is used on a
system where not all of these libraries were detected when <code>avram</code>
was installed from a source distribution. (See <a href="Parameter-Mode-Options.html#Parameter-Mode-Options">Parameter Mode Options</a>.)
Because <code>avram</code> is useful even without interactive applications,
these libraries are not considered absolute prerequisites by the
configuration script.
</p></dd>
<dt> <code>avram: can't emulate version <var>version</var></code></dt>
<dd><a name="index-can_0027t-emulate-version"></a>
<a name="index-emulation-command-line-option-1"></a>
<a name="index-versions"></a>
<a name="index-backward-compatibility"></a>
<p>The &lsquo;<samp>--emulation=<var>version</var></samp>&rsquo; option obviously won&rsquo;t work if
the requested version is newer than the installed version, or if it is
not a valid version number (<a href="General-Options.html#General-Options">General Options</a>). When that happens,
this message is printed instead and <code>avram</code> terminates.
</p></dd>
<dt> <code>avram: multiple version specifications</code></dt>
<dd><a name="index-multiple-version-specifications"></a>
<p>The &lsquo;<samp>--emulation=<var>version</var></samp>&rsquo; option can be used at most once
on a command line. This message is printed if it is used more than
once. If you only typed it once and got this message, check your aliases
and wrapper scripts before reporting a bug.
</p></dd>
<dt> <code>avram: unrecognized option: <var>option-name</var></code></dt>
<dd><a name="index-unrecognized-option"></a>
<p>may mean that a command line option has been misspelled, or may be another
sign of an obsolete version of <code>avram</code>. This message will be followed
by a usage summary similar to that of the &lsquo;<samp>--help</samp>&rsquo; option.
(<a href="General-Options.html#General-Options">General Options</a>).
</p></dd>
<dt> <code><var>application-name</var>: warning: search paths not supported</code></dt>
<dd><a name="index-search-paths"></a>
<a name="index-paths"></a>
<a name="index-environment-2"></a>
<a name="index-AVMINPUTS-1"></a>
<a name="index-search-paths-not-supported"></a>
<a name="index-argz_002eh"></a>
<p>If the &lsquo;<tt>argz.h</tt>&rsquo; header file was not detected during configuration,
<code>avram</code> will not be able to support search paths in the
<code>AVMINPUTS</code> environment variable (<a href="Environment.html#Environment">Environment</a>). This message
is a warning that the environment variable is being ignored. If the
warning is followed by an i/o error
(<a href="i_002fo-Errors.html#i_002fo-Errors">i/o Errors</a>), the latter may be due to a file being in a path that
was not searched for this reason. A workaround is to specify the full
path names of all input files outside the current working directory. If
you don&rsquo;t need search paths, you can get rid of this message by
undefining <code>AVMINPUTS</code>.
