A given target may be 48supported for multiple architectures (see <a href="Architecture-Selection.html#Architecture-Selection">Architecture Selection</a>). 49A target selection may also have variations for different operating 50systems or architectures. 51 52 <p>The command to list valid target values is ‘<samp><span class="samp">objdump -i</span></samp>’ 53(the first column of output contains the relevant information). 54 55 <p>Some sample values are: ‘<samp><span class="samp">a.out-hp300bsd</span></samp>’, ‘<samp><span class="samp">ecoff-littlemips</span></samp>’, 56‘<samp><span class="samp">a.out-sunos-big</span></samp>’. 57 58 <p>You can also specify a target using a configuration triplet. This is 59the same sort of name that is passed to <samp><span class="file">configure</span></samp> to specify a 60target. When you use a configuration triplet as an argument, it must be 61fully canonicalized. You can see the canonical version of a triplet by 62running the shell script <samp><span class="file">config.sub</span></samp> which is included with the 63sources. 64 65 <p>Some sample configuration triplets are: ‘<samp><span class="samp">m68k-hp-bsd</span></samp>’, 66‘<samp><span class="samp">mips-dec-ultrix</span></samp>’, ‘<samp><span class="samp">sparc-sun-sunos</span></samp>’. 67 68<h4 class="subheading"><samp><span class="command">objdump</span></samp> Target</h4> 69 70<p>Ways to specify: 71 72 <ol type=1 start=1> 73<li>command line option: <samp><span class="option">-b</span></samp> or <samp><span class="option">--target</span></samp> 74 75 <li>environment variable <code>GNUTARGET</code> 76 77 <li>deduced from the input file 78 </ol> 79 80<h4 class="subheading"><samp><span class="command">objcopy</span></samp> and <samp><span class="command">strip</span></samp> Input Target</h4> 81 82<p>Ways to specify: 83 84 <ol type=1 start=1> 85<li>command line options: <samp><span class="option">-I</span></samp> or <samp><span class="option">--input-target</span></samp>, or <samp><span class="option">-F</span></samp> or <samp><span class="option">--target</span></samp> 86 87 <li>environment variable <code>GNUTARGET</code> 88 89 <li>deduced from the input file 90 </ol> 91 92<h4 class="subheading"><samp><span class="command">objcopy</span></samp> and <samp><span class="command">strip</span></samp> Output Target</h4> 93 94<p>Ways to specify: 95 96 <ol type=1 start=1> 97<li>command line options: <samp><span class="option">-O</span></samp> or <samp><span class="option">--output-target</span></samp>, or <samp><span class="option">-F</span></samp> or <samp><span class="option">--target</span></samp> 98 99 <li>the input target (see “<samp><span class="command">objcopy</span></samp> and <samp><span class="command">strip</span></samp> Input Target” above) 100 101 <li>environment variable <code>GNUTARGET</code> 102 103 <li>deduced from the input file 104 </ol> 105 106<h4 class="subheading"><samp><span class="command">nm</span></samp>, <samp><span class="command">size</span></samp>, and <samp><span class="command">strings</span></samp> Target</h4> 107 108<p>Ways to specify: 109 110 <ol type=1 start=1> 111<li>command line option: <samp><span class="option">--target</span></samp> 112 113 <li>environment variable <code>GNUTARGET</code> 114 115 <li>deduced from the input file 116 </ol> 117 118 </body></html> 119 120
