Since it just installs target packages, which causes this issue -- that really is the problem. If someone WANTS ldconfig, this could fail for them (without a message explaining "why"). If someone doesn't want ldconfig, it's not really all that obvious how to disable it. I suspect in my own distributions I need to just unconditionally set the DISTRO_FEATURES_BACKFILL_CONSIDERED line. --Mark -- _______________________________________________ Openembedded-core mailing list [email protected] http://lists.openembedded.org/mailman/listinfo/openembedded-core
