[yocto] Where should I append Yocto bitbake task to create work folder symlink ?

[Woronicz, Bartosz ( NSN - PL/Wroclaw)]

Whoa,

That's great! However I modified it, so the link will be relative

The problem is that it works until you have sstate cache empty, because 
after that it doesn't fetch and unpack when already have it in

do_latest_link() {
	if [ -n "${WORKDIR}" ]; then
		linkname="$(basename $(dirname ${WORKDIR}))/latest"
		rm -f $linkname
		ln -s ${WORKDIR} $linkname
	fi
}
addtask latest_link after do_unpack


Kind regards,
