15<p>
16 The <code class="filename">LIC_FILES_CHKSUM</code>
17 variable contains checksums of the license text in the
18 source code for the recipe.
19 Following is an example of how to specify
20 <code class="filename">LIC_FILES_CHKSUM</code>:
21 </p>
22<pre class="literallayout">
23 LIC_FILES_CHKSUM = "file://COPYING;md5=xxxx \
24 file://licfile1.txt;beginline=5;endline=29;md5=yyyy \
25 file://licfile2.txt;endline=50;md5=zzzz \
26 ..."
27 </pre>
28<p>
29 </p>
30<div class="note" title="Notes" style="margin-left: 0.5in; margin-right: 0.5in;">
31<h3 class="title">Notes</h3>
32<div class="itemizedlist"><ul class="itemizedlist" type="disc">
33<li class="listitem"><p>
34 When using "beginline" and "endline", realize
35 that line numbering begins with one and not
36 zero.
37 Also, the included lines are inclusive (i.e.
38 lines five through and including 29 in the
39 previous example for
40 <code class="filename">licfile1.txt</code>).
41 </p></li>
42<li class="listitem"><p>
43 When a license check fails, the selected license
44 text is included as part of the QA message.
45 Using this output, you can determine the exact
46 start and finish for the needed license text.
47 </p></li>
48</ul></div>
49</div>
50<p>
51 </p>

53 The build system uses the
54 <a class="link" href="../ref-manual/var-S.html" target="_self"><code class="filename">S</code></a>
55 variable as the default directory when searching files
56 listed in <code class="filename">LIC_FILES_CHKSUM</code>.
57 The previous example employs the default directory.
58 </p>
59<p>
60 Consider this next example:
61 </p>
62<pre class="literallayout">
63 LIC_FILES_CHKSUM = "file://src/ls.c;beginline=5;endline=16;\
64 md5=bb14ed3c4cda583abc85401304b5cd4e"
65 LIC_FILES_CHKSUM = "file://${WORKDIR}/license.html;md5=5c94767cedb5d6987c902ac850ded2c6"
66 </pre>
67<p>
68 </p>
69<p>
70 The first line locates a file in
71 <code class="filename">${S}/src/ls.c</code> and isolates lines five
72 through 16 as license text.
73 The second line refers to a file in
74 <a class="link" href="../ref-manual/var-WORKDIR.html" target="_self"><code class="filename">WORKDIR</code></a>.
75 </p>
76<p>
77 Note that <code class="filename">LIC_FILES_CHKSUM</code> variable is
78 mandatory for all recipes, unless the
79 <code class="filename">LICENSE</code> variable is set to "CLOSED".
