Hey everyone, I cannot compile librespot with JackAudio backend.
I'm compiling on a Raspberry Pi 1st Generation (arm).
I also tried to cross compile for it today on a x86 machine with the docker file provided.

Steps to reproduce:
execute cargo build --no-default-features --release --features --jackaudio-backend on a ARMv6 Machine
Expected Result:
librespot does compile without error
Actual Result:
Compilation of librespot-playback v0.1.0 fails.
When running verbose, I'm getting this log:

Seems like this issue got introduced with this commit.
I have just manually undone this commit and compilation worked for me (I don't have experience with rust though so I do not know the clean way to resolve this issue)

@SirJson commented on GitHub (May 13, 2018):

Have you tried removing that semicolon see if the JACK backend still works? Looks like a typo to me because that semicolon prevents returning the value pcm_to_f32 calculates.

... unfortunately I don't have JACK on my system installed to verify this myself but the code would at least compile.

Sorry I meant to reply to this, I agree with @SirJson: remove that semicolon.

@SirJson Unfortunately it does not work for me.
As soon as I'm trying to connect to the Raspberry Pi the jackaudio backend tries to connect to the jack server which is clearly running on my system.

Here the full log from journalctl:

Indeed /tmp/jack-109/default/jack_0 does not exist on my machine.
The jack server is running at socket /tmp/jack-1000/default/jack_0.

According to the log messages the error has to be somewhere below here.

Edit: This is using jackd1

@StopMotionCuber commented on GitHub (May 14, 2018):

I replaced jackd1 with jackd2 and journalctl has different error messages for the jackd calls.
I'm not sure if this is relevant but I thought that additional information would be nice for someone debugging this.
