Rustup: Can't install rustup (Void Linux-musl)

[lynxcs]

Hello,
I'm not sure if I'm just dumb or if it's an issue, apologies if it's the former.
I'm trying to install rustup on void linux (musl based). During the curl / sh thing on the website it just complains about not finding rustup-init (somewhere in /tmp/random_letters_here/rustup-init directory).
So then I tried compiling from source but it always fails because of a missing dependency (openSSL).
I tried cargo update and cargo clean with no luck. Maybe it doesn't compile because void linux uses LibreSSL. I don't know.
Anyways I'd really appreciate it if someone would help me with this.

Update: I managed to build it (maybe I confused that part with building rust?) but now the executables in ~/.cargo/bin/ don't work.

The script also doesn't work for me (alpine linux, also musl) with the same error.

Turns out that the rustup-init binary is linked to glibc, so it will fail:

paradoxspiral@misaki> ld rustup-init

…

Providing a rustup-init that is linked against musl, and detecting that in the script would be awesome!

Hey, I have the same issue. Would love a musl linked rustup-init! Is there something that can be done on our part?

Cheers!

I just encountered the same issue trying to install Rust in a CI environment. The image I'm working with is built on alpine linux which doesn't use glibc, hence the cryptic "not found" error message when the OS tries to load rustup-init into memory.

For what it's worth, Void appears to feature a "rustup" package in its repository:

https://www.voidlinux.eu/packages/

Could we backport this into rustup's official downloads?

[rosstimson]

There is indeed a rustup package for Void Linux, however when you are using the musl version of Void it is as good as useless as you cannot install a toolchain. Unless I'm missing something -- I'm new to Void and Rust. I ended up uninstalling rustup and fell back to the void packaged rust and cargo.

[mcandre]

I'm grateful for Void offering rust and cargo for musl in the main xbps repository, however for my purposes I actually need rust nightly, so that I can continue using clippy to analyze my code.

I have the same issue, using alpine here.

rpi [~]$ curl https://sh.rustup.rs -sSf | sh
info: downloading installer
sh: /tmp/tmp.gEbhdG/rustup-init: not found

same issue for me. Is there any update on this?

Dup of #1053.

We've added musl as a build target for rustup in June.
