Detailing the build directory
The build directory is a central information and artifact source for every Poky user. Its main directories are the following:
conf: This has the configuration files we use to control Poky and BitBake. The first use of this directory was 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 can be seen as the download cache and has been detailed in Chapter 4, Grasping the BitBake Tool.sstate-cache: This has the packaged data snapshots. It is a cache mainly used to speed up the build process. This folder is detailed in Chapter 6, Assimilating Packaging Support.tmp: This is the temporary build directory and the main focus of this chapter.
