I have a small question : I have installed 1.4 through rustup.sh. What is the clean way to upgrade to 1.5 ? I don't think there is some kind of 'rustup.sh upgrade' Delete 1.4 & reinstall ? Or downloading rustup 1.5 will apply a clean install on the existing one ?
Run rustup.sh again, and it will Just Work. (If not, that's a bug.) If you want to have multiple versions installed at the same time, https://github.com/brson/multirust is super cool. Generally speaking, installation is something we're working on: working with Linux package maintainers, rolling rustup and multirust together and making them work well cross-platform, etc.
Never heard of programming but you still want to compile a project?
Step 1: run rustup.sh (curl -sSf https://static.rust-lang.org/rustup.sh | sh)
Step 2: clone the repo of the project or your regional equivalent
Step 3: cargo build --release (or now with the new cargo install feature, cargo install)
Step 4: Enjoy
