<h3 class="section">17.1 Target Selection</h3>
<p>A <dfn>target</dfn> is an object file format. A given target may be
supported for multiple architectures (see <a href="Architecture-Selection.html#Architecture-Selection">Architecture Selection</a>).
A target selection may also have variations for different operating
systems or architectures.
<p>The command to list valid target values is <span class="samp">objdump -i</span>
(the first column of output contains the relevant information).
<p>Some sample values are: <span class="samp">a.out-hp300bsd</span>, <span class="samp">ecoff-littlemips</span>,
<span class="samp">a.out-sunos-big</span>.
<p>You can also specify a target using a configuration triplet. This is
the same sort of name that is passed to <span class="file">configure</span> to specify a
target. When you use a configuration triplet as an argument, it must be
fully canonicalized. You can see the canonical version of a triplet by
running the shell script <span class="file">config.sub</span> which is included with the
sources.
<p>Some sample configuration triplets are: <span class="samp">m68k-hp-bsd</span>,
<span class="samp">mips-dec-ultrix</span>, <span class="samp">sparc-sun-sunos</span>.
