| <h3 class="section">C.4 Specifying Names for Hosts and Targets</h3> |
| |
| <p>The specifications used for hosts and targets in the <samp><span class="file">configure</span></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: |
| |
| <pre class="smallexample"> <var>architecture</var>-<var>vendor</var>-<var>os</var> |
| </pre> |
| <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=</code><var>target</var> |
| option. The equivalent full name is ‘<samp><span class="samp">sparc-sun-sunos4</span></samp>’. |
| |
| <p>The <samp><span class="file">configure</span></samp> script accompanying <span class="sc">gdb</span> does not provide |
| any query facility to list all supported host and target names or |
| aliases. <samp><span class="file">configure</span></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: |
| |
| <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> |
| <p class="noindent"><code>config.sub</code> is also distributed in the <span class="sc">gdb</span> source |
| directory (<samp><span class="file">gdb-8.3.0.20190709-git</span></samp>, for version 8.3.0.20190709-git). |
