<h3 class="section">18.1 Target Selection</h3>
|
|
<p>A <em>target</em> 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>
|
<p>The command to list valid target values is ‘<samp>objdump -i</samp>’
|
(the first column of output contains the relevant information).
|
</p>
|
<p>Some sample values are: ‘<samp>a.out-hp300bsd</samp>’, ‘<samp>ecoff-littlemips</samp>’,
|
‘<samp>a.out-sunos-big</samp>’.
|
</p>
|
<p>You can also specify a target using a configuration triplet. This is
|
the same sort of name that is passed to <samp>configure</samp> 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 <samp>config.sub</samp> which is included with the
|
sources.
|
</p>
|
<p>Some sample configuration triplets are: ‘<samp>m68k-hp-bsd</samp>’,
|
‘<samp>mips-dec-ultrix</samp>’, ‘<samp>sparc-sun-sunos</samp>’.
