Hi :) I have this problem too: http://ardour.org/node/2271 If I go back to the Suse 11.0 version before 0.116, it's 0.109, the message changes from "jackd: symbol lookup error: jackd: undefined symbol: clock_source" to "jackd: symbol lookup error: jackd: undefined symbol: _jack_get_microseconds". I tried to write with the German community (at Linux-Club Suse and Packman community) about such issues, but they aren't interested in their bugs and because they laugh about me, I'm not interested anymore to report anything to them. Everything I tried to inform about, should be wrong they say and laugh and there were a lot of bugs similar to that one, for audio and MIDI realtime applications from the standard repositories Oss, Non-Oss, Updates, Packman and VideoLAN. Also there are often versions that aren't good for professional work. I removed the jack package by YaST2 and then ... suse11:/usr/lib # rm libjack* suse11:/usr/lib64 # rm libjack* After I installed jack again, I got "jackd: error while loading shared libraries: libjackserver.so.0: cannot open shared object file: No such file or directory". Does anybody know a Suse community that is interested to solve those things? I'm fine with the Debian 64 Studio audio community. Isn't there such a friendly community for Suse (not JAD)? For some reasons I like to use Debian 64 Studio and Suse, but Suse often is a pain in the arse, because of a narrow views having community. Do I need to compile jack myself for Suse 11.0? Before I upgraded jack, I don't get any error messages. Cheers, Ralf
