Problem compiling jack2 with opus

[asbaklm]

Hi there

I'm trying to compile jack2 on Mint / Ubuntu 14.04 with opus for netjack2 but it doesn't seem to like the opus_custom.h file and fails. jack2 builds provided --opus=no is specified.

I'm using latest opus 1.1.2. For some reason opus also doesn't install opus_custom.h in /usr/local/include/opus so this has to be copied in manually.

There aren't any Ubuntu libopus-dev packages installed on the system.

What am I doing wrong, or is netjack2 opus not working at the moment?

Hi!

Well, there are a few glitches in the build system which are on my ToDo list, but I am terribly short on time for the time being. See #176. Also #37 is relevant. You will definitely need the -dev packages to build jack2 from source anyway, but as noted in #37 you will not get the opus_custom.h header, which is needed.

In the end you will need opus built with --custom-modes, which Mint does not provide, so you will need to compile it from source.

PR #145 is also related.

I see!

Thanks a lot for the clarification about building Opus with --custom-modes.

The jack dev package I used on Ubuntu/Mint was this one. libjack-jackd2-dev:amd64

I then created and installed a dummy jackd package and put it on hold to try and prevent any accidental installations of jack packages so I didn't have both Ubuntu libraries and self-compiled ones on the system.

PR#145 was interesting to read. Many thanks again, I really appreciate your help.

So I tried it after removing previous opus build and replacing it with newly compiled versions with --custom-modes but it still doesn't seem to work.

There aren't any Ubuntu opus dev packages installed, the previous opus libraries were uninstalled.
I tried it with opus 1.1.2 and opus 1.1.1

Are you compiling with --mixed? In that case you also need to compile opus as a 32-bit library.

[asbaklm]

Yes I was using --mixed. Thank you very much, I hadn't realised.
