Welcome to Rust!
This will download and install the official compiler for the Rust programming
language, and its package manager, Cargo.
It will add the cargo, rustc, rustup and other commands to Cargo's bin
directory, located at:
/home/xxxxx/.cargo/bin
This path will then be added to your PATH environment variable by modifying the
profile file located at:
/home/xxxxx/.profile
You can uninstall at any time with rustup self uninstall and these changes will
be reverted.
Current installation options:
default host triple: x86_64-unknown-linux-gnu

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH
environment variable. Next time you log in this will be done automatically.
To configure your current shell run source $HOME/.cargo/env
2. IDEはEclipseをインストール
- Eclipse公式サイト から
Eclipse SimRel 2018‑09をダウンロード。 - インストーラーを実行し、
Eclipse IDE for Rust developersを選択してインストール。
3. プロジェクトの作成と実行
Cargo projectを作成。main.rsをRunしようとすると、Install missing rls component in Rustupと、言われるのでrlsコンポーネントをインストールします。
$ rustup component add rls-preview
main.rsをRunしたところ今度は
$ rustc main.rs error: linker `cc` not found | = note: No such file or directory (os error 2) error: aborting due to previous error
と、言われたので
$ sudo apt install build-essential
- 3度目の正直で再度
main.rsをRun
無事 Hello, world! と出力されました!!
