Can't get slskd to run on osmc/rpi4

[MitraMai]

Hello! I have 2 rpi4, one running raspberry pi OS, and one running OSMC. Raspberry Pi Os is the latest one, Debian Bullseye, while OSMC is still at Buster. For some reason I get slskd to (the downloaded binaries, the slskd-0.15.5-linux-arm.zip ) run on Raspberry Pi OS, but not on OSMC. On OSMC, using the binaries from slskd-0.16.0-linux-arm.zip, arm I get osmc@Rubicon:~/System/slskd$ ls config etc LICENSE slskd wwwroot osmc@Rubicon:~/System/slskd$ ./slskd Bussfel That is "bus error" in swedish. Using the binaries from slskd-0.16.0-linux-arm64.zip I get: osmc@Rubicon:~/System/slskd$ ls config etc LICENSE slskd wwwroot osmc@Rubicon:~/System/slskd$ ./slskd bash: ./slskd: Filen eller katalogen finns inte Which means "File or folder not found".

I've tested with both version 0.15 and 0.16. Is there I way I can debug this? I'm unable to find any flag for more a verbose output. From the OSMC forum I found this regarding OSMC on RPI4:

The kernel will be 64-bit Userland is armhf (32-bit)

I think I have some gaps in my understanding of bit-ness on arm platforms, so while I'm generally quick to point the finger at 32bit-anything, I'm not sure that's fair. A "bus error" sounds consistent with an inability to address memory and thus an incompatibility somewhere between 32/64 bit-ness, though.

The "file or folder not found" error sounds similar to errors I would get when trying to work with Alpine Linux and musl-libc. I used to build musl binaries, the latest of which can be found here: https://github.com/slskd/slskd/releases/download/0.9.6/slskd-0.9.6-linux-musl-x64.zip

Please give that a shot and report back when you get a minute.

Thank you for your answer! I tried both the arm and the arm64 versions. The arm64 version does not work. But the arm-version starts. But then I can't get slskd to run since it complains about: Invalid configuration: System.FormatException: Could not parse the YAML file. But that's another problem. So I guess you're right in your hunch the musl-libc. So, is there a way to include musl-libc in the newest versions or am I to use version 0.9.6 if I want to use slskd on OSMC? I could always use my other PI but I prefer the OSMC-one since I already setup external HDD etc on it.

Starting with the 0.16.1 release, linux-musl-x64 binaries will be included. This release will be out about 30 minutes from this post.

I wouldn't worry about errors with the older version, the yaml file has changed a lot since then. Once the release is out, download the latest binaries and see how they work for you.

Hello again! Nah, can't get it to work. Still getting "bus error" when using the arm-version, and "file or folder not found" when trying the arm64-version. I guess it is due to the fact that OSMC uses 32-but userland. What that means in practice I can only guess. But I assume that to get slskd to work on OSMC, OSMC has to ship with musl-binaries (?) or that OSMC has to be 64-bit in all aspects, not just the kernel. But anyway, thanks for your help. It's been very kind of you!

I can't recreate the exact scenario because I don't yet own a Raspberry Pi 4 (I could try with an RPI3 but it's a hassle and nobody has complained about RPI3 issues so I'm not sure it would be worthwhile)

I did update the build to include more binaries, and will update it again once .NET 7 is available to add the new x86 and armv6 options.

The latest release is here: https://github.com/slskd/slskd/releases/tag/0.16.2 and if you aren't tired of messing with this, you might try linux-muscl-arm.

I do generally think this is being caused by some weirdness with OSMC; I can run both the linux-arm binaries and the armv7 Docker image on my Raspberry Pi 2 running 32 bit Raspbian OS.

Just tried the new binaries. Not working :( Not musl-arm nor musl-arm4. I'm getting the same error as before, but now on both binaries:

osmc@Rubicon:~/System/slskd$ ls config etc LICENSE slskd slskd-0.16.2-linux-musl-arm64.zip wwwroot osmc@Rubicon:~/System/slskd$ chmod +x slskd osmc@Rubicon:~/System/slskd$ ./slskd bash: ./slskd: Filen eller katalogen finns inte

osmc@Rubicon:~/System/slskd$ chmod +x slskd osmc@Rubicon:~/System/slskd$ ./slskd bash: ./slskd: Filen eller katalogen finns inte 127 osmc@Rubicon:~/System/slskd$ ls config etc LICENSE slskd slskd-0.16.2-linux-musl-arm.zip wwwroot (File or folder not found)

I agree with you that it's probably something weird with OSMC. I'm gonna ask at the forum and get back here if I get any answers. Again, thanks for trying to help me out!

I'll leave this issue open; please report back if you figure out what the issue is.
