<h3 class="section">C.4 Specifying Names for Hosts and Targets</h3>
|
||
|
|
|
||
|
|
<p>The specifications used for hosts and targets in the <samp>configure</samp>
|
||
|
|
script are based on a three-part naming scheme, but some short predefined
|
||
|
|
aliases are also supported. The full naming scheme encodes three pieces
|
||
|
|
of information in the following pattern:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample"><var>architecture</var>-<var>vendor</var>-<var>os</var>
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>For example, you can use the alias <code>sun4</code> as a <var>host</var> argument,
|
||
|
|
or as the value for <var>target</var> in a <code>--target=<var>target</var></code>
|
||
|
|
option. The equivalent full name is ‘<samp>sparc-sun-sunos4</samp>’.
|
||
|
|
</p>
|
||
|
|
<p>The <samp>configure</samp> script accompanying <small>GDB</small> does not provide
|
||
|
|
any query facility to list all supported host and target names or
|
||
|
|
aliases. <samp>configure</samp> calls the Bourne shell script
|
||
|
|
<code>config.sub</code> to map abbreviations to full names; you can read the
|
||
|
|
script, if you wish, or you can use it to test your guesses on
|
||
|
|
abbreviations—for example:
|
||
|
|
</p>
|
||
|
|
<div class="smallexample">
|
||
|
|
<pre class="smallexample">% sh config.sub i386-linux
|
||
|
|
i386-pc-linux-gnu
|
||
|
|
% sh config.sub alpha-linux
|
||
|
|
alpha-unknown-linux-gnu
|
||
|
|
% sh config.sub hp9k700
|
||
|
|
hppa1.1-hp-hpux
|
||
|
|
% sh config.sub sun4
|
||
|
|
sparc-sun-sunos4.1.1
|
||
|
|
% sh config.sub sun3
|
||
|
|
m68k-sun-sunos4.1.1
|
||
|
|
% sh config.sub i986v
|
||
|
|
Invalid configuration `i986v': machine `i986v' not recognized
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p><code>config.sub</code> is also distributed in the <small>GDB</small> source
|
||
|
|
directory (<samp>gdb-8.3</samp>, for version 8.3).
