[Pkg-dns-devel] Bug#801611: knot: duplicate definition of base32hex_encode

[Michael Tautschnig]

Package: knot
Version: 2.0.1-4
Usertags: goto-cc
Tags: upstream

During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder
and pbuilder) the build failed with the following error. Please note that we
use our research compiler tool-chain (using tools from the cbmc package), which
permits extended reporting on type inconsistencies at link time.

It seems there are two full (yet different) implementations of a function with
the same name; it is left to the linker to hopefully pick the most appropriate
one.

This is certainly an upstream issue, but as the package maintainer is part of
the upstream team and I'm not signed up to upstream's bug tracker it's hopefully
ok to report this to the Debian BTS...

Best,
Michael
