There is two different objectives in this. Per-recipe staging and per-package build-time dependencies. While I assume per-recipe staging will be doable to build on top of sstate, per-package build-time dependencies is not really related to sstate, but is mostly a meta-data issue (man-hours wise), while also requiring changes to tbe BitBake cooker. The final thing that I have found while solving the above issues, is how simple (KISS!) all this can be addressed when going from per-recipe build-time dependencies to per-package. And I really think that we need more KISS in OE ;-) /Esben _______________________________________________ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
