Seems like the bug was inactive during sometime so I just fork the repository and update to the latest current version of libczmq, 2.2.0. * http://anonscm.debian.org/cgit/users/jrivero-guest/czmq.git Let me know if there is any error and if someone is interested in sponsor the upload. Thanks. -- Jose Luis Rivero <jrivero@osrfoundation.org>
