Installing clippy

[idubrov]

Is there any way I can install rust-src component on top of this image (which is required by clippy)?

This image doesn't include rustup (with which you can do rustup component add rust-src) and I cannot quite figure out what exactly I need to do to emulate rustup comuonent add rust-src.

Oh, interesting, didn't know clippy required this now.

I think you need to grab the corresponding nightly source tarball and extract it somewhere (similar to old racer setup).
Clippy install seems to require SYSROOT=/path/to/rustc/sysroot cargo install clippy without rustup.

Ok, I was completely wrong about rust-src. The real cause was that clippy would be installed for musl target, which lacks librustc.

The correct way to install clippy on top of this image is:

CARGO_BUILD_TARGET=x86_64-unknown-linux-gnu cargo install clippy

Ah, thanks for the update. I'll make a note of it in the README for future people :-)
