You can find the configuration actually used in the build in TMPDIR/work/i586-poky-linux-uclibc/uclibc-0.9.32- r4.3/git/.config (directory names may vary slightly depending on your build configuration). With master, when I checked my version of that file, UCLIBC_HAS_RESOLVER_SUPPORT=y is set, so apparently this feature is getting enabled by default. However, when I did the same on edison (which uses uclibc 0.9.32 as opposed to 0.9.33) that setting is not present. Digging around I'm beginning to wonder if this option was perhaps added in uclibc 0.9.33, which if true would explain why it is not present when building uclibc in edison; but does that mean the underlying functionality was added in that version or just the option? More detective work - the dn_comp() function was indeed not in uclibc until 0.9.33; also, the reference to dn_comp() was added in the following commit to iputils: http://www.linux- ipv6.org/gitweb/gitweb.cgi?p=gitroot/iputils.git;a=commitdiff;h=ac3fe58bc1939c8ed3cf34c30f713dfe82b27ce5 So I guess you have a few options: 1) Avoid using iputils altogether - you can get very basic versions of the utilities in iputils from busybox. Looks like on the face of it nothing depends on iputils but it is pulled in via task-core-basic (which is pulled in by core-image-basic). 2) Upgrade to uclibc 0.9.33 (can be done in a separate layer on top of edison) 3) Patch iputils to remove the call to this function and any others that aren't in uclibc 0.9.32 4) Patch iputils to not build ping6 5) Build an older version of iputils Cheers, Paul -- Paul Eggleton Intel Open Source Technology Centre ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
