We decided a few years ago to no longer make ipv6 support in packages optional, i.e. always assume it is there. Note that even if the kernel is built without IPv6 support, it is possible to run executables in it that are built with IPv6 support - but obviously no IPv6 connection will ever be made. So you can just unconditionally enable IPv6 support in nfs-utils. Except, apparently, nfs-utils requires libtirpc for IPv6 support, as witnessed by this commit: commit e23be36ab3a110787917db59618d9f5280457938 Author: Peter Korsgaard <jacmet@sunsite.dk> Date: Wed Apr 25 22:29:34 2012 nfs-utils: fix build with ipv6 after 2a10c9 (pass --enable-ipv6 to autotargets configure) IPv6 support needs the TIRPC library, which we don't have in Buildroot, so forcibly disable IPv6 support. Now, that's a commit from 6 years ago, so the situation may have changed. Therefore, please try if it is possible to build and run nfs-utils *without* libtirpc and *with* --enable-ipv6. If that works, just enable ipv6 unconditionally. If it doesn't work, add the --enable/disable-ipv6 to the existing libtirpc condition in nfs-utils.mk. In that case, please also make a note in the commit message that native RPC is being deprecated so libtirpc (and therefore IPv6) will be enabled unconditionally in the future. I'm taking this one. Patch submitted: https://patchwork.ozlabs.org/patch/1145462/ (In reply to Carlos Santos from comment #3) Patch updated: https://patchwork.ozlabs.org/patch/1145827/ Discussing the subject in the mailing list it was decided to keep libtirpc optional so I submitted a second patch that builds nfs-utils with IPv6 enabled if libtirpc is selected: https://patchwork.ozlabs.org/patch/1159968/ Fixed by https://git.buildroot.org/buildroot/commit/?id=749334cb36ea5c0a0fd745dada43122f88a3144c. Thanks a lot Carlos for your work on this issue! |
