cargo wasix build fails: could not execute rustc

[jessbowers]

On a fresh install of Debian 11 with the latest rustup 1.26.0 following this plan:

mkdir app && cd app
cargo init
cargo install cargo-wasix
cargo wasix build

The toolchain reports that it's linked & available, but I get a ton of errors related to libc not found. Then a final "could not execute rustc"

Trying to build the toolchain from scratch, I got another error:

@theduke can you try to reproduce it?

Note that using Debian 12 does not have this issue. I think it has to do with the version of GLIBC

[Dzejkop]

I'm seeing the same issue:

OS: Ubuntu 20.04.6 LTS on Windows 10 x86_64
Kernel: 5.15.90.1-microsoft-standard-WSL2

> cargo --version
cargo 1.73.0-nightly (d78bbf4bd 2023-08-03) (but same issue happened with 1.68)

> rustc --version
rustc 1.73.0-nightly (28eb857b9 2023-08-12)

> cargo wasix --version
cargo-wasix 0.1.21

Updating to Ubuntu 22.04 resolved the issue

This is also an issue for me on Debian 11.
