System Information
Operating system: OSX High Sierra 10.13.6
Graphics card: Intel HD Graphics 4000

Blender Version
Broken: (2.83.3)
Worked: (unknown)

Short description of error

Blender is not showing Jack in the audio devices list.
Typing bpy.app.build_options.Jack in the python console drops False.
Jack server is properly installed prior to Blender and working fine with other applications.

Exact steps for others to reproduce the error

Under OSX High Sierra 10.13.6 install the latest version of Jack Audio from the official site (JackOSX 0.92_b3). Then install Blender 2.83.3. Although Jack is installed and properly working in other applications, Blender won't detect it and won't show it in the audio devices' list.

When building 2.90 from the source I detected the error. The file jack.h and other jack related files weren't found in the location requested by Blender's installer, because the installer was requesting them in a .../jack/ subfolder. Duplicating Jack files to a .../jack/ subfolder solved the problem. Blender built then correctly and Jack appeared in the devices' list afterwards. Timeline sync using Jack Transport is working as well.

In concrete, I duplicated the files in /Library/Frameworks/Jackmp.framework/Versions/A/Headers/ to the created subfolder /Library/Frameworks/Jackmp.framework/Versions/A/Headers**/jack/** to bypass the error. But the former is the folder where Jack installs by default under High Sierra.

@lichtwerk I don't have a Mac, so I cannot really be aware of the issue :-/

If the jack headers are indeed not in a jack subfolder on MacOS, that is an issue. I can at least confirm that on Linux and Windows the jack headers are always in a folder <somewhere>/include/jack/ and the documentation always refers to the headers with their jack/ folder. That the jack folder itself is not to be added to the include directories of a project is also confirmed by the fact, that the pkg-config for jack does not output the cflags in that way. If the official MacOS jack libraries are really shipped without the jack folder, that should be reported upstream; otherwise where did you get the library from?

There was an issue in macOS cmake library/framework finding code which got fixed in 8f2ebcf93f.
Please retry on a fresh build after updating the code.

Also having this issue and copying over files into a /jack subfolder does not fix this
Jack is not important to me and it’s stopping the whole build…

Any chances that Blender MacOS will get updated to allow building it with the latest Jack 1.9?

Blender builds successfully when locating jack.h and related files in two consecutive folders /jack and /jack/jack of the previous version 0.9. More specifically copying the files in /Library/Frameworks/Jackmp.framework/Versions/A/Headers/ to subfolders /Library/Frameworks/Jackmp.framework/Versions/A/Headers/jack and /Library/Frameworks/Jackmp.framework/Versions/A/Headers/jack/jack. After this the jack framework is detected and WITH_JACK can be made effective.

But the new Jack version for MacOS doesn't work, the service jackd clashes with itself (Blender clashes with another client running). Below a copy of the error the system console gives. If there is a workaround please let me know! I tried disabling the prelaunch of jackd agent but that comes only one step closer.

Jack a is a very powerful tool for me, it allows syncing the playhead transport with audio editing softwares and the new 1.9 version is a very neat update. Also useful for working with multiple sound cards or serving multiplatform audio workflows.

– Tests made from Catalina 10.15.7 and Blender 3.5.

This is weird. Again, I cannot test MacOS, since I don't have a Mac. At least here on Linux everything works fine with any 1.9.x version of jack (the jack2 series of releases that have version numbers 1.9.x have been out for several years already).

Maybe one of the MacOS platform maintainers (@ArtoKitula @brecht @sebbas) could look into this?

Jack has not been enabled in macOS builds for a long time, as the framework is not installed on the buildbot. I can look into enabling it somehow.

However it's not clear to me what to link against exactly to make this work for end users. When downloading version 1.9.21 from https://jackaudio.org/downloads/ or installing from homebrew, I don't get any framework installed in /Library/Frameworks/Jackmp.framework. There are headers and libraries in /usr/local and /opt/homebrew instead.

@domingo, how did you install Jack? Does 1.9 no longer include the framework and you found a leftover from an older Jack version? Or did I miss something?

@brecht as far as I can remember (I've been migrating to linux lately honestly) the steps I followed were:

Install the old JackOSX 0.9 from https://github.com/jackaudio/jackaudio.github.com/releases
Install the new Jack Audio 1.9, I think its source files (*.h) came to Brew's Cellar folder.
Replace the old 0.9 source files for the new 1.9 ones, particularly those in /Library/Frameworks/Jackmp.framework. Important was to create copies of the files in .../Jackmp.framework/jack and Jackmp.framework/jack/jack.

Thanks for the details.

@neXyon, I guess we can target jack2 only on macOS, and not support the old jackOSX?

For that we need to switch to WITH_JACK_DYNLOAD. And audaspace needs changes in plugins/jack/JackLibrary.cpp to find the library, the same 4 paths as here could be tested:
https://github.com/x42/weakjack/blob/master/weak_libjack.c#L108

Sure, anything that works is fine for me. Actually, if we use dynload, I think it would even work with the old jack since afaik they are API compatible.

Regarding installation - all I did at the time I had a Mac available was brew install jack, but not sure if that still works, since that was at least three years ago.
