Any way to get this working with jack-audio on a windows system

[markweenwork]

I normally use linux and use jack for audio routing along with jack_mixer for general volume control - I also use jack in windows and was wondering if its possible to build jack_mixer for windows 10?

[SpotlightKid]

I honestly don't know. I don't have a Windows 10 system and I haven't tried crosss-compiling jack_mixer yet.

There are a few things that would need to be adapted in the code, e.g. signal handling and preferences saving paths.

So, volunteers needed to work on this.

[markweenwork]

thanks for the info and thanks for this tool - very useful in my opinion!!
would love to be able to have the same audio setup in windows that i currently use in linux

[markweenwork]

I managed to get this working in windows 10 -
i compiled using msys2 on windows 10

1. had to compile portaudio with asio driver enabled
2. compile the correct version of jack2
3. i could then pull in the prebuilt packages in msys2 of glib2, python-gobject, python-cairo, python-xdg
4. in the c source i had to remove some signal references as suggested by spotlightKid and had to do the same in the py files
5. could now install the same version of jack as the version i compiled against and run it
6. launch jack_mixer

spent most the weekend figuring this out - will look more into this next weekend when i have some more time and see if i can find any parts that dont work - and also look at the preferences saving paths

thanks for the pointers in the right direction spotlightkid!!!

[SpotlightKid]

Great news!

Please share your work, when you find the time!

For the preferences path I was thinking about replacing pyxdg with appdirs.

[markweenwork]

yes i intend to share everything!!
will update next weekend!

[markweenwork]

hey sorry for delay with this - had my hard disk fail last weekend and then also my backup hardisk failed while trying to recovery my main disk lol!!
ok so what I have below is instrutions on 64 bit windows to compile and run jack and jack_mixer15 from source using msys2 - I am looking to gather all dependencies together to make it easier for normal users to get this going as it is quite long winded atm

firstly the downloads needed using the versions i used are as follows

https://github.com/jackaudio/jack2-releases/releases/download/v1.9.17/jack2-win64-v1.9.17.exe
https://github.com/jackaudio/jack2/archive/refs/tags/v1.9.17.tar.gz

Thanks for that. I'll have a closer look as soon as I can.

Why do you need to build jack? Wouldn't it be enough to point meson at the jack headers?

[markweenwork]

hi
i built jack because it wasnt finding the jack libs because the jack.pc file was missing from the lib/pkgconfig folder and i didnt know how to create it - building jack created this file for me
if i had know how to create it or if i got a correct .pc file i could have avoided building jack

[SpotlightKid]

jack_mixer, now that PR #150 is merged, now uses appdir to save preferences and mixer setting files in the correct locations, which should work on windows too, so that's one step further towards windows compatibility, I hope.

[shushz]

@markweenwork, thank you so much for the Jack building instructions, they are great! FYI, the process of building portaudio with ASIO support seems to have changed somewhat, at least it didn't work out of the box, but I didn't use ASIO and too was only building jack for its jack.pc.
