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
●
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.
