@patatetom apparently kyotocabinet fails to build with GCC 6 and above, but this bug is fixed at least in Debian and Fedora. Could you check if your distribution package of kyotocabinet is up to date?

according to the pkgbuild, I think the patch is not built in : I'm gonna get closer to the maintainer. thanks Artem.
