error: Could not compile syntex_syntax about librespot HOT 26 CLOSED

I had this exact error once.
I think this is what helped.

From memory is was due to a versioning issue.

Let me know if you need more help.

Thank you for the reply I will try to update rustup and check it if it helps.

from librespot.

Hello,

I need help, I can't find how to downgrade rust. I'm using rustup.

from librespot.

Hey @lionas89,

Just wondering why you are downgrading rust?

I've just complied it on the latest to check and also made Travis do it again to confirm.

Can you share more of the errors you are getting. (If they are very ling use a gist or pastebin)

Hello,

Thank you for the response.

In the link you provided, one user message was:

But then I had to brew switch rust 1.1.0 backwards because bad cargo is in the homebrew rust 1.2.0 package: Homebrew/legacy-homebrew#42992

Sure I can:

Ah I see what's happened, from what I've seen the latest release is fine.

What operating system are you using?
Have you tried running "rustup update"?

from librespot.

Here is information:
https://pastebin.com/XGcdVvQy

root@chip:~# rustup update
info: syncing channel updates for 'stable-armv7-unknown-linux-gnueabihf'
info: checking for self-updates

stable-armv7-unknown-linux-gnueabihf unchanged - rustc 1.23.0 (766bd11c8 2018-01-01)

I followed steps in this tutorial:
https://bbs.nextthing.co/t/howto-chip-or-chip-pro-as-spotify-connect-radio/17621

from librespot.

And you got the same error after the update?
Have you tried from a fresh install?
And did you run:
sudo apt-get update
sudo apt-get upgrade
to get it all up to date?
I presume you are running CHIP Operating System?

(Note: I don'r have a CHIP to help you but am looking at buying one. Also I think the above commands are correct from the documentation.)

from librespot.

Yes,
here is the output:
https://pastebin.com/pcdKPTt1

I think I'm faced the low memory issue. Is there a way to compile on PC and transfer it to CHIP?

from librespot.

Sorry for the long wait for a reply!

I'm looking at your logs now

from librespot.

Hello,

Thank you. I'm waiting for your response. :)

from librespot.

Just to confirm you have tried a complete reinstall of CHIP OS and install of rust using rustup?

from librespot.

Also I'll try cross compiling it for you later tonight, it's not ideal but it would be a short cut.

Many thanks

Yes, I have tried fresh CHI and install using rustup. I followed @brat steps. Tried his compiled version of @brat, but I got an error:

Thank you very much for help. 👍

from librespot.

Try running it without the username and password so just

./librespot --name "CHIP"

from librespot.

Same issue. This appears when I try to connect with remote device to play song.

from librespot.

OK I'm running a cross compiling job now and will upload the version that may work for you.

And as you saw I have commented asking if brad had any success with this fork.

Try that it may work, though I won't get our hopes up.

from librespot.

It is working at the moment. I can control it on my phone and it's what I need. Thank you very much. If I will face any issue I will let you know. Honestly, BIG THANK YOU!!! 🥇

from librespot.

No problem :) That's good to hear! Not quite sure what caused your issue but Glad you have it sorted.

I'll close this for now. Let me know if you have any other issues.

from librespot.

This seems to be exactly the problem I'm stuck with. Wanted to give the cross-compiled download a few posts up a try, but it doesn't seem to be available anymore. Not sure it would be the right platform anyway, though, I'm on a raspberry B+, not sure if that matches the CHIP.

While compiling the syntex_syntax, kswapd takes over all processing power at a certain moment, processor load goes up to 30+, and at some point the build process fails.

P.S. the reason I'm trying to compile my own librespot on the raspberry B+ is that the precompiled one I'm using now results in the following error shortly after starting it:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: WireError("invalid value for enum: 13")', /checkout/src/libcore/result.rs:859

P.P.S. I realise I'm replying to a closed issue, but since it seems to match the issue I'm having, I thought this would be better than opening a new issue. My apologies if that's not the desired way.

from librespot.

Just as a nice easy solution have you had a look at Raspotify?
It is basically a wrapper for librespot and will save you compiling it yourself?

If you want to try the version above (I'm not sure it would work) The link changed and can now be found here.

Let me know how it goes!

from librespot.

The precompiled librespot is clearly not matching my architecture, it segfaults upon startup. Raspotify, I had not heard of that, but that sounds very promising, I'll be sure to take a look at that! Thanks for pointing me there!

from librespot.

Let me know if you have any more issues and I can cross compile one for the pi but Raspotify should sort you out.

from librespot.

Raspotify sorts me out, 98%. Now I'm stuck with an alsa issue, probably some other sound-related process preventing raspotify/librespot from accessing the device.

Mar 04 12:58:09 max2play librespot[3045]: ERROR:librespot_playback::audio_backend::alsa: Alsa error PCM open -16
Mar 04 12:58:09 max2play librespot[3045]: ERROR:librespot_playback::player: Could not start audio: Alsa error: PCM open failed

But now I'm diverting quite a bit from the original issue posted here, and I hope with some more searching on the internet and trying out I can figure this out... So, thanks for the help, issue closed for me.

Raspotify was an excellent suggestion, thanks for that!

Edit: got it working at last. Note to self: if you kill other processes that claim alsa, make sure there's no automatic restart for these processes in place... ;)

@crushert good to hear!
