Error with kyotocabinet member function.

I had error at make step: In file included from kcdbext.cc:16:0:

Thanks for any help on the issue.

It looks like an issue with kyotocabinet when ussing gcc 6/7: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=811627

One possible workaround would be to include that patch from here: http://pkgs.fedoraproject.org/cgit/rpms/kyotocabinet.git/commit/?h=f24&id=988ed3a17b1a5ba659c4f3758b5a262859b0e4e1
