docker build fails - librespot package version issue?

[mwild1]

Thanks for the project! I've been using it happily for years, practically daily :)

Unfortunately it broke recently, so I decided it was time to update. However I'm having difficulty getting the new version to build. I had some local modifications, but I just tried a clean clone of the repo and that also fails.

Building the latest revision on 2024-12-23, commit e31a64f, it fails to build:

What's the recommended solution here?

It looks like librespot has been updated in alpine, so I submitted a PR to bump the package version in the dockerfile, which appears to fix the build.

Unfortunately it doesn't appear to fix my playback issue, which seems to match snapcast/snapcast#1186 which is apparently fixed in snapcast v0.27.0 (librespot-snapserver is currently on 0.26.0).

I'm not sure how to upgrade snapcast to a newer version... attempting to increase the version gives me similar errors to the one that I opened this issue about, although I see 0.29.0 seems to be available in alpine. Any ideas?

Okay, bumping the overall alpine version was the answer here. I eventually got everything working on alpine 3.21, so we can finally enjoy some festive music. I hope you can too! 🙂
