[HELP] ARM64 Linux release requires musl, but Raspberry Pi OS uses glibc — recommended way to run podkit?

[crwntec]

Hi!

I'm trying to use podkit as a headless iPod synchronization service on a Raspberry Pi 4.

My goal is fairly simple: I run Navidrome on the Pi, manage my music/podcasts remotely, and have the Pi automatically synchronize my iPod whenever it is placed in its USB dock. Ideally the workflow would be:

Navidrome → podkit → iPod Nano

so I can manage the library from my phone/PC and simply pick up the iPod from the dock when I want to use it.

I have an iPod nano 2nd generation, and podkit looks like an unusually good fit for this use case.

Environment

• Raspberry Pi 4
• ARM64 / aarch64
• Raspberry Pi OS / Debian-based Linux
• glibc
• Navidrome
• iPod nano 2nd generation

Problem

I tried installing the Homebrew package:

brew install jvgomg/podkit/podkit

Homebrew currently attempts to download:

podkit-linux-arm64-gnu.tar.gz

from the 0.6.0 release, but that asset doesn't appear to exist, resulting in a 404.

I then downloaded the ARM64 release asset manually:

podkit-linux-arm64.tar.gz

The binary is:

ELF 64-bit LSB executable, ARM aarch64, dynamically linked,
interpreter /lib/ld-musl-aarch64.so.1

My Raspberry Pi OS installation is glibc-based, so running it results in:

cannot execute: required file not found

ldd confirms that the musl runtime isn't available:

libc.musl-aarch64.so.1 => not found

I also checked the podkit-daemon-linux-arm64.tar.gz release, and it appears to have the same musl dependency.

Question

What is the recommended way to run podkit on an ARM64 Raspberry Pi running Debian/Raspberry Pi OS?

Would you recommend:

1. Building podkit from source against glibc;
2. Installing/running a musl environment on the Pi;
3. Running the official binary in an Alpine/musl container;
4. Something else?

Also, is the missing podkit-linux-arm64-gnu.tar.gz asset intentional, or is the Homebrew formula currently out of sync with the release assets?

I'm happy to provide any additional diagnostics or test a build if that would help.

Thanks — podkit looks like exactly the tool I've been looking for to turn a Raspberry Pi + Navidrome + docked iPod into an automated sync appliance.
