Compile standalone and plugins in Debian Linux stretch. #13

Closed ritsch closed 4 years ago

ritsch commented 7 years ago

Hello,

Last month I managed to compile ambix both on Debian stable and used it in a concert quite well. (not extensivly testing) but binaural-decoder, decoder and also encoder with GUI on testing (see script I used on various machines) using jack. (also decoder as vst does not work, but standalone)

Debian Strech:

Switch back to c++ gnu version 5, since 6 is now didnt compile
libeigen downgrade

Now I compiled again: (after a git pull) now it compiles also using gcc-6, good,but

standalone programs does not have the right number of jack channels, always 12 ?
lv2 fails to initiate on loading
vst crashes

What was the change ? only the juce library update Any hints ?

Appendix: FYI, script to build ambix on debian::

Found the error for wrong jack channel numbers: have to apply the patch in JUCE now manually before Build, since patch Hunk #3 is rejected.

Is this correct ?

Hi @ritsch , thanks for your feedback!

The last commits included an update to the new version of JUCE, yes. I did not do a proper crosscheck whether things still work under Linux with the new JUCE version.

Regarding the standalone version you are correct, I did not update the jack patch. I did this now and the standalone version works fine.

Regarding LV2 and VST I guess things might be more complicated. I quickly tried the VST versions with Ardour5 and the GUI seems to crash Ardour. However, with Carla they work...

Did you find out something already?

ritsch commented 7 years ago

Thanks for fast response.

I will do tests on linux next week for a project using ardour5 but first 'lv2_jack_host' and report.

Is the jack pacth needed or should I try to get same behaviour without patching JUCE ?

kronihias commented 7 years ago

patching juce_linux_JackAudio.cpp is needed, otherwise the standalone versions have a wrong input/output channel count. (JUCE will only create the number of physical input/output channels of the soundcard, which makes no sense for JACK.)

I did raise this in the forum long time ago: https://forum.juce.com/t/jackaudioiodevice-input-output-channel-count/10384
