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

You should definitely not do that.
/usr/local/lib and /usr/local/lib64 are for libraries that you compile
locally from source.
/usr/lib and /usr/lib64 are for libraries installed by your distro's
package manager.
Putting anything else there will may confuse the package manager
sooner or later when you do a system update.
The problem is probably that your system is not configured to use
libraries in /usr/local.
To fix this (as root)
1. Move the libraries back to their original locations under /usr/local
2. Using any text editor, Create a file
local.conf
in the directory
/etc/ld.so.conf.d
The file should contain these two lines:
/usr/local/lib
/usr/local/lib64
3. Run the command ldconfig
4. Reboot
There will be an update of jacktools very soon.
Mostly bugfixes etc. but JackGainctl will change.
The 'rate' parameter in set_gain is no longer supported.
The rate is now fixed to 600 dB/s expect for mute /unmute
which will always take 10 milliseconds.
Ciao,

Hello Fons, hello Frank,
thank you very much for help and the info. Now I got it to work! :)
But only with a very special tweaking:
I had to rename the folder "utils" to "utils2" and update the import
to
"utils2.kmeters" to get it to work.
Really weird, maybe "utils" is used somewhere else on my system?
@Fons: Could it be possible to add the installation info you gave me in
the previous mail to the Readme of jacktools? I don't know it this was
only on my system, but since I'm using LinuxMint (Ubuntu-based), this
could be an interesting information for more people.
Now it's time to dive into jacktools... great!
All the best,
Vince

Hi Vince,
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.
You likely forgot to update the shared loader's cache by running "ldconfig"
(as root). This is always necessary after installing new shared libraries.
Also, instead of copying the shared libraries from /usr/local/lib64 to /usr/lib64,
I suggest you add your /usr/local/lib64 path to the loader's search path
(perhaps by creating a new file in /etc/ld.so.conf.d/, this is slightly
dependant on your distribution).
Greetings,
Frank
