build eroot$ bitbake core-image-minimal -c fetchall FATAL: /dev/shm does not exist or is not writable This is in a default setup with the meta-darwin layer added.
meta-darwin enables us to build SDKs which run on OSX, it does not let us run bitbake on OSX unfortunately. There has been talk about making that work but it would require significant effort which we simply don't have the resources for at this time.
