Hello everyone, I'm trying to install and use zita-jacktools, but unfortunately I don't get it to work. https://media.ccc.de/v/lac2018-46-jacktools_realtime_audio_processors_as_py… I managed to compile it and install it. According to http://linux-audio.4202.n7.nabble.com/zita-jacktools-available-now-td106280…, I needed also to compile zita-convolver 4.0.0 first, which I did, and which also went well. I've done the following: 1. download and unpack: - zita-audiotools - zita-jacktools - zita-jclient - zita-convolver 4.0 2. make and install zita-jclient and zita-convolver: - go to source, them make, then sudo make install 3. install zita-audiotools and zita-jacktools: - go to folder, then python3 setup.py build - then install with sudo python3 setup.py install Now I can import jacktools in Python without errors. But if I try to use it OR to run an example file (e.g. tobspect.py like in the ccc video), I get the following error: ImportError: libzita-jclient.so.0: cannot open shared object file: No such file or directory In the nabble thread, a user said that zita-jclient is installed to /usr/local/lib64, but zita-jacktools only included /usr/lib as the library path. So I copied libzita-convolver and libzita-jclient from /usr/local/lib64 to /usr/lib, but I still get the same error message. Does someone have any hint? I'm developing a open source Python application, where I really need fast and rock solid interpolation for the mixer faders, so I'd really love to use JackGainctl for this.... Here the full error message: File "/media/sda7/Programming/Python/jacktooltest/main.py", line 3, in <module>     from jacktools import jackkmeter   File "/usr/local/lib/python3.6/dist-packages/jacktools/jackkmeter.py", line 22, in <module>     from jacktools.jackclient import JackClient   File "/usr/local/lib/python3.6/dist-packages/jacktools/jackclient.py", line 21, in <module>     from jacktools import jackclient_ext ImportError: libzita-jclient.so.0: cannot open shared object file: No such file or directory Thank you for any help! All the best, Vince
