Detailing the build directory
The build directory is a central information and artifact source for every Poky user. Its main directories are as follows:
conf: This contains the configuration files we use to control Poky and BitBake. We first used this directory in Chapter 2, Baking Our Poky-Based System. It stores configuration files, such asbuild/conf/local.confandbuild/conf/bblayers.conf.downloads: This stores all the downloaded artifacts. It works as a download cache. We talked about it in detail in Chapter 5, Grasping the BitBake Tool.sstate-cache: This contains the snapshots of the packaged data. It is a cache mainly used to speed up the future build process, as it is used as a cache for the building process. This folder is detailed in Chapter 7, Assimilating Packaging Support.tmp: This is the temporary build directory and the main focus of this chapter.
