<h2 class="chapter">18 Selecting the Target System</h2>

<p>You can specify two aspects of the target system to the <small>GNU</small>
binary file utilities, each in several ways:
</p>
<ul>
<li> the target

</li><li> the architecture
</li></ul>

<p>In the following summaries, the lists of ways to specify values are in
order of decreasing precedence.  The ways listed first override those
listed later.
</p>
<p>The commands to list valid values only list the values for which the
programs you are running were configured.  If they were configured with
<samp>--enable-targets=all</samp>, the commands list most of the available
values, but a few are left out; not all targets can be configured in at
once because some of them can only be configured <em>native</em> (on hosts
with the same type as the target system).
