Tracking image, package, and SDK contents


The easiest way to ensure we have the image, packages, and SDK, along with the expected contents, is to use the Build History mechanism. Its contents may change in unexpected ways when we change a recipe.

When a recipe is updated for a new version or has its code changed, it may influence the contents put in the generated packages and, as consequence, in the image or SDK.

As Poky deals with a huge amount of recipes, and our images or SDKs frequently have tens or hundreds of packages included, it may be quite difficult to track the package contents. The Poky tool responsible to help us in this task is the Build History.

The Build History, as we can guess from its name, keeps the history of contents of several artifacts built during the Poky use. It can track package, image, and SDK building.

To enable the Build History in our system, we need to add the following lines of code in our local.conf file:

INHERIT += "buildhistory" 
BUILDHISTORY_COMMIT = "1"...
