multirust fails on Raspbian

[MaxDesiatov]

multirust output:

pi:~ $ curl -sf https://raw.githubusercontent.com/brson/multirust/master/blastoff.sh | sh

Welcome to Rust.

This script will download, build, and install multirust as root, then
configure multirust with the most common options. It may prompt for
your password for installation via 'sudo'.

You may run /usr/local/lib/rustlib/uninstall.sh to uninstall multirust.

Ready? (y/N) y

blastoff: installing stable toolchain
multirust: installing toolchain 'stable'
rustup: gpg available. signatures will be verified
rustup: downloading manifest for 'stable'
rustup: couldn't find remote installer for 'arm-unknown-linux-gnueabihf' in manifest
blastoff: failed to install stable toolchain. if this appears to be a network problem retry with `multirust default stable`

[brson]

Huh. I don't see the error in this log. Do you?

[brson]

Do the manual installation instructions work? IOW is it just blastoff.sh that's broken?

[andrewtj]

Had a quick play on my pi:

% multirust update nightly
multirust: installing toolchain 'nightly'
rustup: gpg available. signatures will be verified
rustup: downloading manifest for 'nightly'
/tmp/multirust/usr/bin/rustup.sh: 1007: /tmp/multirust/usr/bin/rustup.sh: CFG_CPUTYPE: parameter not set

That would have been set based on uname -m which reports armv6l. Is that supported?

[MaxDesiatov]

sorry about incomplete log, I've updated it with the full report, error line is rustup: couldn't find remote installer for 'arm-unknown-linux-gnueabihf' in manifest

[brson]

Ah! OK. That makes sense. rustup/multirust download binaries from the official distribution channels, and we don't publish bins for arm-unknown-linux-gnueabihf. @alexcrichton @edunham and I are working on expanding our hardware support, and we may be able to make this platform available before too long.

In the meantime, you can use multirust to manage locally-built toolchains, though it may not provide much value.
