Understanding the sysroot directories
The sysroot
directory plays a critical role in the Yocto Project. It creates an individual and isolated environment for each recipe. This environment, set for each recipe, is essential to ensure reproducibility and avoid contamination with the host machine’s packages.
After we build the procps
recipe, version 3.3.17
, we get two sets of sysroot
directories – recipes-sysroot
and recipes-sysroot-native
.
Inside each sysroot
set, there is a sub-directory called sysroot-provides
. This directory lists the packages installed on each respective sysroot
. Following is the recipe-sysroot
directory:

The recipe-sysroot-native
directory includes the build dependencies used on the host system during the build process. It encompasses the compiler, linker, tools, and more. At the same time, the recipe-sysroot
