info: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:

/home/defaultuser/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory located at:

/home/defaultuser/.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

/home/defaultuser/.cargo/bin

This path will then be added to your PATH environment variable by
modifying the profile files located at:

/home/defaultuser/.profile
/home/defaultuser/.bash_profile

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.
Current installation options:

default host triple: aarch64-unknown-linux-gnu
default toolchain: stable
profile: default
modify PATH variable: yes

1. Proceed with installation (default)
2. Customize installation
3. Cancel installation

stable installed - (error reading rustc version)

Rust is installed now. Great!

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH
environment variable. Next time you log in this will be done
automatically.

To configure your current shell run source $HOME/.cargo/env
I tried this code:

rustc -V
I expected to see this happen: rustc 1.48.0 (7eac88a 2020-11-16)

Instead, this happened: error: command failed: 'cargo' error: caused by: No such file or directory (os error 2)'

Meta

There is the same in the beta or nightly versions.

rustc --version --verbose:

Hi, this is fascinating because clearly the rustup itself works, and yet the installed toolchain does not.

Could you please ensure strace is installed on your system and then do:

rustup run strace -o try-run-rustc.txt rustc --version

Attach the resulting file, and paste the output, in a new comment.

Thanks.

[corvinux]

Hi Daniel,
Yes, it is, fascinating :) I'm trying running rustup (rustc, cargo) on Sony Xperia X running Sailfish OS 3.4.0.24. Otherwise there is distribution rust installation package (rust, cargo, Version: 1.44.0+git3-1.2.3.jolla) which works just fine.

rustup run stable strace -o try-run-rustc.txt rustc --version
[error:]command failed: 'rustc'
error: caused by: No such file or directory (os error 2)
try-run-rustc.txt

[kinnison]

Next could you run ls -l .rustup/toolchains/stable*/bin/ and assuming that shows a rustc binary, try running ldd on that binary.
e.g. ldd .rustup/toolchains/stable*/bin/rustc

[corvinux]

ldd rustc
not a dynamic executable
[defaultuser@XperiaX bin]$ ls -lsah rustc
16 -rwxr-xr-x 1 defaultu defaultu 14.3K Nov 24 21:18 rustc
[defaultuser@XperiaX bin]$ file rustc
rustc: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 4.2.6, not stripped

[kinnison]

Okay, so when you posted the ldd of rustup I assumed you had a multiarch system.

The output of ldd rustc suggests you don't - and in fact despite having an aarch64 CPU you're running an armhf userland which is something we weren't expecting.

Were you expecting to run the 64 bit arm toolchain on that system, or were you hoping for an armhf toolchain?

[corvinux]

Yes, exactly that's it. SailfishOS is actually running 32bit apps in userspace. I remember now, that I also asked this question on Jolla forum https://together.jolla.com/question/192062/whan-will-sailfish-os-become-full-64-bit-os/
Also, when I've installed Rust package from SailfishOS repository
Repository : jolla

Summary : The Rust Programming Language
Description :
Rust is a systems programming language that runs blazingly fast, prevents
segfaults, and guarantees thread safety.

This package includes the Rust compiler and documentation generator.

[defaultuser@XperiaX ~]$ file /usr/bin/rustc

I wasn't thinking about toolchain, I just wanted to install rust with rustup.

I'm back on track, thank you Daniel.

rustup run strace -o try-run-rustc.txt rustc --version

After running this command i am getting this :

error: Found argument '-o' which wasn't expected, or isn't valid in this context

USAGE:

For more information try --help

please guide me towards it.
