Original GitHub issue: https://github.com/librespot-org/librespot/issues/678

I'm using Ubuntu 20.04 and I'm unable to compile librespot with the following command: sudo cargo build --release. If you need any more info please let me know.

error: could not compile protobuf.

Works fine for me. Did you try it several times or just once? You're log has a strange formatting, but it seems as if it was simply killed.

Edit: Maybe the OOM killer? Do you have enough RAM?

I have tried it several times over the past few weeks.

Thank you for your suggestion. I only have 1 GB ram, however, the library has been compiled a couple of months ago with the same amount of ram. I tried disabling the overcommit of OOM, but this results in multiple errors, I couldn't even get to the library folder.

okay so I've tried it once again and for some reason, protobuf compiled correctly but now it got an error on librespot-protocol.

Is this a RAM issue or could it be something else?

I really think it's a RAM issue.

You said yourself that you don't have much RAM.
The error does not occur deterministically.
The rust process is killed with SIGKILL and that's exactly what a OOM killer would do.
protobuf and librespot-protocol belong to the more resource-intensive crates while compiling, so it makes sense that it aborts there.

You could try to google for tricks to compile rust programs with little memory, or if you don't find anything, ask on users.rust-lang.org

1GB is enough to compile even with all features. Surely this is not a librespot bug.

I believe I have encountered this before when I used to use a RPi 2 as a connect receiver. I'd suggest either cross compiling or a swap file of 2G or so, though this won't be great for the SD card if that's what you're running it off. Anyway, closing as this isn't a librespot bug from what I can tell.
