BoF: Multibuild for Zephyr RTOS
Talkat Open Source Summit Europe + Embedded Linux Conference Europe 2019 · on Monday, 2019-10-28· at 18:00· Forum 6·
summary
Zephyr gains a CMake non‑recursive multibuild implemented as a West-aware build that uses add_subdirectory plus a new image switch to namespace per-image targets and properties. It ships in Nordic downstream and integrates with Segger Embedded Studio, gives one dependency graph so header/link steps parallelize and shared Kconfig/device-tree checks catch incompatibilities, but it currently forbids multiple toolchains and increases CMake complexity and maintenance burden.
