<h3 class="section">18.7 GDB Data Files</h3>

<a name="index-prefix-for-data-files"></a>
<p><small>GDB</small> will sometimes read an auxiliary data file.  These files
are kept in a directory known as the <em>data directory</em>.
</p>
<p>You can set the data directory&rsquo;s name, and view the name <small>GDB</small>
is currently using.
</p>
<dl compact="compact">
<dd><a name="index-set-data_002ddirectory"></a>
</dd>
<dt><code>set data-directory <var>directory</var></code></dt>
<dd><p>Set the directory which <small>GDB</small> searches for auxiliary data files
to <var>directory</var>.
</p>
<a name="index-show-data_002ddirectory"></a>
</dd>
<dt><code>show data-directory</code></dt>
<dd><p>Show the directory <small>GDB</small> searches for auxiliary data files.
</p></dd>
</dl>

<a name="index-default-data-directory"></a>
<a name="index-_002d_002dwith_002dgdb_002ddatadir"></a>
<p>You can set the default data directory by using the configure-time
&lsquo;<samp>--with-gdb-datadir</samp>&rsquo; option.  If the data directory is inside
<small>GDB</small>&rsquo;s configured binary prefix (set with &lsquo;<samp>--prefix</samp>&rsquo; or
&lsquo;<samp>--exec-prefix</samp>&rsquo;), then the default data directory will be updated
automatically if the installed <small>GDB</small> is moved to a new
location.
</p>
<p>The data directory may also be specified with the
<code>--data-directory</code> command line option.
See <a href="Mode-Options.html#Mode-Options">Mode Options</a>.
