3.10.2.1. Setting Up and Running a Multiple Configuration Build

To accomplish a multiple configuration build, you must define each target's configuration separately using a parallel configuration file in the Build Directory, and you must follow a required file hierarchy. Additionally, you must enable the multiple configuration builds in your local.conf file.

Follow these steps to set up and execute multiple configuration builds:

Note

Support for multiple configuration builds in the Yocto Project 2.7 (Warrior) Release does not include Shared State (sstate) optimizations. Consequently, if a build uses the same object twice in, for example, two different TMPDIR directories, the build either loads from an existing sstate cache for that build at the start or builds the object fresh.
