| <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-7.10.1.20160210-cvs</samp>, for version 7.10.1.20160210-cvs). |
