image dependencies into a task-depends.dot file:bitbake -g <image>
task-depends.dot for the package you are interested in (i.e. which packages are pulling in llvm):cat task-depends.dot | grep llvm | grep populate
Note: it is not always obvious what is the final value of any given Yocto variable, since they can be overwritten from different layers. It is therefore highly recommended to check the value with bitbake-getvar.
bitbake-getvar -r <image> <variable>
i.e. bitbake-getvar -r lmp-devel-arduino-image USERADD_GID_TABLES .
bitbakeThis is i.e. necessary when building the x8h7 kernel modules which are a dependency of meta-partner-arduino.
