You can see debug output from BitBake by using the <code class="filename">-D</code> option.
|
||
The debug output gives more information about what BitBake
|
||
is doing and the reason behind it.
|
||
Each <code class="filename">-D</code> option you use increases the logging level.
|
||
The most common usage is <code class="filename">-DDD</code>.
|
||
</p>
|
||
<p>
|
||
The output from <code class="filename">bitbake -DDD -v targetname</code> can reveal why
|
||
BitBake chose a certain version of a package or why BitBake
|
||
picked a certain provider.
|
||
This command could also help you in a situation where you think BitBake did something
|
||
unexpected.
