The idea behind external/opencv was that all packages needing a very decent opencv version depend on this package rather than the one from the os packing system. But at the moment external/opencv defined in rock/source.yml is even older than the one shipped with Ubuntu 12.04 being the oldest ubuntu version we support.</span></font></span></div><div><br></div><div><span style="background-color: rgb(255, 255, 255); color: rgb(51, 51, 51); font-family: arial, 'lucida grandriale', 'lucida sans unicode', tahom, sans-serif; line-height: 18px;">Alex</span></div><div><br></div><br><blockquote type="cite"><br>-- <br> --<br> Matthias Goldhoorn<br> Unterwasserrobotik<br> Standort Bremen:<br> DFKI GmbH<br> Robotics Innovation Center<br> Robert-Hooke-Straße 5<br> 28359 Bremen, Germany<br> Phone: +49 (0)421 218-64100<br> Fax: +49 (0)421 218-64150<br> E-Mail: <a href="mailto:robotik@dfki.de">robotik@dfki.de</a><br> Weitere Informationen: <a href="http://www.dfki.de/robotik">http://www.dfki.de/robotik</a><br> -----------------------------------------------------------------------<br> Deutsches Forschungszentrum fuer Kuenstliche Intelligenz GmbH<br> Firmensitz: Trippstadter Straße 122, D-67663 Kaiserslautern<br> Geschaeftsfuehrung: Prof. Dr. Dr. h.c. mult.
