Changing the folder that holds the YP Reference Manual to be "ref-manual". This will help with confustion over the manual's intended purpose.

|
||
<a name="usingpoky-specifying-LIC_FILES_CHKSUM"></a>3.4.1.1. Specifying the <code class="filename">LIC_FILES_CHKSUM</code> Variable</h4></div></div></div>
|
||
<p>
|
||
The <code class="filename">LIC_FILES_CHKSUM</code>
|
||
variable contains checksums of the license text in the source code for the recipe.
|
||
Following is an example of how to specify <code class="filename">LIC_FILES_CHKSUM</code>:
|
||
</p>
|
||
<pre class="literallayout">
|
||
LIC_FILES_CHKSUM = "file://COPYING;md5=xxxx \
|
||
file://licfile1.txt;beginline=5;endline=29;md5=yyyy \
|
||
file://licfile2.txt;endline=50;md5=zzzz \
|
||
..."
|
||
</pre>
|
||
<p>
|
||
</p>
|
||
<p>
|
||
The build system uses the
|
||
<code class="filename"><a class="link" href="ref-variables-glos.html#var-S" title="S">S</a></code> variable as the
|
||
default directory used when searching files listed in
|
||
<code class="filename">LIC_FILES_CHKSUM</code>.
|
||
The previous example employs the default directory.
|
||
</p>
|
||
<p>
|
||
You can also use relative paths as shown in the following example:
|
||
</p>
|
||
<pre class="literallayout">
|
||
LIC_FILES_CHKSUM = "file://src/ls.c;startline=5;endline=16;\
|
||
md5=bb14ed3c4cda583abc85401304b5cd4e"
|
||
LIC_FILES_CHKSUM = "file://../license.html;md5=5c94767cedb5d6987c902ac850ded2c6"
|
||
</pre>
|
||
<p>
|
||
</p>
|
||
<p>
|
||
In this example, the first line locates a file in
|
||
<code class="filename">${S}/src/ls.c</code>.
|
||
The second line refers to a file in
|
||
<code class="filename"><a class="link" href="ref-variables-glos.html#var-WORKDIR" title="WORKDIR">WORKDIR</a></code>, which is the parent
|
||
of <code class="filename"><a class="link" href="ref-variables-glos.html#var-S" title="S">S</a></code>.
|
||
</p>
|
||
<p>
|
||
Note that this variable is mandatory for all recipes, unless the
|
||
<code class="filename">LICENSE</code> variable is set to "CLOSED".
