As I have mentioned, the major advantage and available feature of the Yocto Project environment is represented by the fact that a Yocto Project build does not use the host available packages, but builds and uses its own packages. This is done to make sure that a change in the host environment does not influence its available packages and that builds are made to generate a custom Linux system. A toolchain is one of the components because almost all packages that are constituents of a Linux distribution need the usage of toolchain components.
The first step for the Yocto Project is to identify the exact sources and packages that will be combined to generate the toolchain that will be used by later built packages, such as U-Boot bootloader, kernel, BusyBox and others. In this book, the sources that will be discussed are the ones available inside the dizzy branch, the latest poky 12.0 version, and the Yocto Project version 1.7. The sources can be gathered using the...
