... big snip ... finally have time to read paul's post on this so i'll go over this again, but it seems that at the very least, what's needed is, in the current reference manual, Chapter 10. Reference:Features:
http://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#ref-features there should be an explanation of COMBINED_FEATURES and how that plays into possible configuration changes. there's absolutely no mention of COMBINED_FEATURES anywhere in the reference manual except in the variable glossary: http://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#var-COMBINED_FEATURES and that explanation seems somewhat inadequate: "A set of features common between MACHINE_FEATURES and DISTRO_FEATURES. See the glossary descriptions for these variables for more information." as i mentioned, that variable is defined *very* explicitly for a *chosen* set of FEATURES in bitbake.conf: COMBINED_FEATURES = "\ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "alsa", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "bluetooth", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "ext2", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "vfat", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "irda", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "pcmcia", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "pci", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "usbgadget", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "usbhost", d)} \ ${@base_both_contain("DISTRO_FEATURES", "MACHINE_FEATURES", "wifi", d)}" COMBINED_FEATURES[vardeps] += "DISTRO_FEATURES MACHINE_FEATURES" and i think that needs to be pointed out so people (like me :-) don't get the wrong idea of what it represents. thoughts? rday -- ======================================================================== Robert P.
