→Building the software components with Yocto
== Building the software components with Yocto ==
The build process creates an entire Linux distribution from source. The build process can be summarized as follows:
* Make sure that all the prerequisites are met
* Initialize the build environment, as described in the following sections
* Optionally ensure the conf/local.conf configuration file, which is found in the Build Directory, is set up how you want it. This file defines many aspects of the build environment including the target machine architecture through the MACHINE variable, the development machine's processor use through the BB_NUMBER_THREADS and PARALLEL_MAKE variables, and a centralized tarball download directory through the DL_DIR variable.
* Build the image using the bitbake command. If you want information on BitBake, see the BitBake User Manual.
N.B. Since the DIVELK virtual machine is already configured to match all the requirements for using the Yocto build system, developers who wants to quickly build a Yocto image can directly go to section [[Software_Manual_(Diva)#Building the Yocto image]].
