| 15 | <p> | ||
| 16 | The <code class="filename">LIC_FILES_CHKSUM</code> | ||
| 17 | variable contains checksums of the license text in the source code for the recipe. | ||
| 18 | Following is an example of how to specify <code class="filename">LIC_FILES_CHKSUM</code>: | ||
| 19 | </p> | ||
| 20 | <pre class="literallayout"> | ||
| 21 | LIC_FILES_CHKSUM = "file://COPYING;md5=xxxx \ | ||
| 22 | file://licfile1.txt;beginline=5;endline=29;md5=yyyy \ | ||
| 23 | file://licfile2.txt;endline=50;md5=zzzz \ | ||
| 24 | ..." | ||
| 25 | </pre> | ||
| 26 | <p> | ||
| 27 | </p> | ||
| 28 | <p> | ||
| 29 | The build system uses the | ||
| 30 | <code class="filename"><a class="link" href="ref-variables-glos.html#var-S" title="S">S</a></code> variable as the | ||
| 31 | default directory used when searching files listed in | ||
| 32 | <code class="filename">LIC_FILES_CHKSUM</code>. | ||
| 33 | The previous example employs the default directory. | ||
| 34 | </p> | ||
| 35 | <p> | ||
| 36 | You can also use relative paths as shown in the following example: | ||
| 37 | </p> | ||
| 38 | <pre class="literallayout"> | ||
| 39 | LIC_FILES_CHKSUM = "file://src/ls.c;startline=5;endline=16;\ | ||
| 40 | md5=bb14ed3c4cda583abc85401304b5cd4e" | ||
| 41 | LIC_FILES_CHKSUM = "file://../license.html;md5=5c94767cedb5d6987c902ac850ded2c6" | ||
| 42 | </pre> | ||
| 43 | <p> | ||
| 44 | </p> | ||
| 45 | <p> | ||
| 46 | In this example, the first line locates a file in | ||
| 47 | <code class="filename">${S}/src/ls.c</code>. | ||
| 48 | The second line refers to a file in | ||
| 49 | <code class="filename"><a class="link" href="ref-variables-glos.html#var-WORKDIR" title="WORKDIR">WORKDIR</a></code>, which is the parent | ||
| 50 | of <code class="filename"><a class="link" href="ref-variables-glos.html#var-S" title="S">S</a></code>. | ||
| 51 | </p> | ||
| 52 | <p> | ||
| 53 | Note that this variable is mandatory for all recipes, unless the | ||
| 54 | <code class="filename">LICENSE</code> variable is set to "CLOSED". | ||
| 55 | </p> | ||
