  58. <h3 class="subsection">1.6.6 Configuration Related Errors</h3>
  59. <p>The source code distribution of <code>avram</code> incorporates a flexible
  60. configuration script allowing it to be installed on a variety of
  61. platforms. Not all platforms allow support for all features. It is also
  62. anticipated that new features may be added to <code>avram</code> from time to
  63. time. Some problems may therefore occur due to features not being
  64. supported at your site for either of these reasons. The following error
  65. messages are relevant to these situations.
  66. </p>
  67. <dl compact="compact">
  68. <dt> <code>unsupported hook</code></dt>
  69. <dd><a name="index-unsupported-hook-1"></a>
  70. <p>If it&rsquo;s not simply due to an application programming error
  71. (<a href="Application-Programming-Errors.html#Application-Programming-Errors">Application Programming Errors</a>) this message may be the result of
  72. trying to use an application that requires a newer version of
  73. <code>avram</code> than the one installed, even though applications should
  74. avoid this problem by checking the version number at run time. If this
  75. is the reason, the solution would be to install the latest version.
  76. </p></dd>
  77. <dt> <code><var>application-name</var>: I need avram linked with <var>foo</var>, <var>bar</var> and <var>baz</var>.</code></dt>
  78. <dd><a name="index-I-need-avram-linked-with"></a>
  79. <p>A message of the this form indicates that a new installation may be
  80. needed. At this writing (11/11/1), <code>avram</code> may report this message
  81. with respect to <code>libexpect5.32</code>, <code>tcl8.3</code>, and <code>libutil</code>
  82. 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
  83. system where not all of these libraries were detected when <code>avram</code>
  84. was installed from a source distribution. (See <a href="Parameter-Mode-Options.html#Parameter-Mode-Options">Parameter Mode Options</a>.)
  85. Because <code>avram</code> is useful even without interactive applications,
  86. these libraries are not considered absolute prerequisites by the
  87. configuration script.
  88. </p></dd>
  89. <dt> <code>avram: can't emulate version <var>version</var></code></dt>
  90. <dd><a name="index-can_0027t-emulate-version"></a>
  91. <a name="index-emulation-command-line-option-1"></a>
  92. <a name="index-versions"></a>
  93. <a name="index-backward-compatibility"></a>
  94. <p>The &lsquo;<samp>--emulation=<var>version</var></samp>&rsquo; option obviously won&rsquo;t work if
  95. the requested version is newer than the installed version, or if it is
  96. not a valid version number (<a href="General-Options.html#General-Options">General Options</a>). When that happens,
  97. this message is printed instead and <code>avram</code> terminates.
  98. </p></dd>
  99. <dt> <code>avram: multiple version specifications</code></dt>
  100. <dd><a name="index-multiple-version-specifications"></a>
  101. <p>The &lsquo;<samp>--emulation=<var>version</var></samp>&rsquo; option can be used at most once
  102. on a command line. This message is printed if it is used more than
  103. once. If you only typed it once and got this message, check your aliases
  104. and wrapper scripts before reporting a bug.
  105. </p></dd>
  106. <dt> <code>avram: unrecognized option: <var>option-name</var></code></dt>
  107. <dd><a name="index-unrecognized-option"></a>
  108. <p>may mean that a command line option has been misspelled, or may be another
  109. sign of an obsolete version of <code>avram</code>. This message will be followed
  110. by a usage summary similar to that of the &lsquo;<samp>--help</samp>&rsquo; option.
  111. (<a href="General-Options.html#General-Options">General Options</a>).
  112. </p></dd>
  113. <dt> <code><var>application-name</var>: warning: search paths not supported</code></dt>
  114. <dd><a name="index-search-paths"></a>
  115. <a name="index-paths"></a>
  116. <a name="index-environment-2"></a>
  117. <a name="index-AVMINPUTS-1"></a>
  118. <a name="index-search-paths-not-supported"></a>
  119. <a name="index-argz_002eh"></a>
  120. <p>If the &lsquo;<tt>argz.h</tt>&rsquo; header file was not detected during configuration,
  121. <code>avram</code> will not be able to support search paths in the
  122. <code>AVMINPUTS</code> environment variable (<a href="Environment.html#Environment">Environment</a>). This message
  123. is a warning that the environment variable is being ignored. If the
  124. warning is followed by an i/o error
  125. (<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
  126. was not searched for this reason. A workaround is to specify the full
  127. path names of all input files outside the current working directory. If
  128. you don&rsquo;t need search paths, you can get rid of this message by
  129. undefining <code>AVMINPUTS</code>.
