[SR-Users] rtpengine key file

Hello I have build rtpengine on a Raspberry PI 3 running Jessie, but it fails on startup pi@raspberrypi:/usr/local/src/rtpengine $ rtpengine --log-level=7 --log-stderr [1486630112.767604] CRIT: Fatal error: Bad command line: Key file does not start with a group Most likely I'm missing something which is found on regular PC Linux distributions. But what? Googling the error message reveals almost nothing and nothing related to rtpengine Any hints will be appreciated. -- Med venlig hilsen / Best regards Kjeld Flarup (Christensen) M.Sc E.E, Teknisk chef Viptel ApS, Hammershusvej 16C, DK-7400 Herning Telefon: +45 46949949, Telefax: +45 46949950, http://viptel.dk
