The lack of C toolchain management yields some errors when trying to cross compile between OSX and linux (both directions). See https://github.com/rust-lang-nursery/rustup.rs/issues/462 and https://github.com/rust-lang-nursery/rustup.rs/issues/463 Been able to cross compile between these systems using rustup, anyone ?

https://github.com/rust-lang-nursery/rustup.rs is the repo. The setup tool and the tool itself are the same binary. The rustup install is basically copying rustup-init.exe to `~/.cargo/bin/rustup.exe`.

Yeah the README has it wrong. https://github.com/rust-lang-nursery/rustup.rs/blob/master/R...

Yes. I might as well take the time to elaborate on the history here. In the beginning, there was rustup. And it was good. Then, Rust matured, and we started the release channels. Now there wasn't just "Rust 0.9", there was Rust stable, beta, 1.0, 1.1... so many versions. rustup.sh wasn't really built to handle that. And so, multirust was born. mutlirust was/is a bash-based shell script that wraps up rustup and gives you the ability to manage multiple installs of Rust. And fun things like "this project uses rust stable, but this project uses Rust 1.1" and "please update every Rust I have installed". Stuff like that. But it was a bash script. Nobody knew that this whole Bash in Windows thing was happening. And we already have a perfectly good, general purpose programming language that runs on all the platforms Rust supports: Rust! So the mu

ltirust-rs project was begun, to re-write multirust in Rust. Once that started to become closer to being finished, we took a step back, looked holistically at all of this, and thought "If we started from scratch, what would we do?" https://public.etherpad-mozilla.org/p/rustup-new-experience And so, "rustup" was born. It's pretty much multirust.rs, but without trying to mimic the old multirust itself. There's still lots of stuff to do before it's ready to become the default way you manage rust installations: https://internals.rust-lang.org/t/beta-testing-rustup-rs/331... and https://github.com/rust-lang-nursery/rustup.rs/issues?q=is%3... And of course, many people will want to use their system package manager too. Choice is good. They also play together. But that's for another post, this one is already getting long. You can find rustup here: https://www.rustup.rs/
