Rust の環境をセットアップする

[53175ddd]

• [x] Rust のインストール

  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
  source "$HOME/.cargo/env"

• [x] クロスコンパイラのインストール

  rustup target add thumbv6m-none-eabi

• [x] ユーティリティのインストール

  cargo install flip-link elf2uf2-rs probe-run

[53175ddd]

rustup done

[53175ddd]

クロスコンパイラ導入 done

cc 入れろと言われたので実行 多分ユーティリティインストール前にやったほうがいい

sudo apt install gcc -y

[53175ddd]

cargo install flip-link elf2uf2-rs probe-run

[53175ddd]

すべての作業の前にやるべきコマンド

sudo apt update && sudo apt upgrade -y

[53175ddd]

sudo apt install pkg-config -y

[53175ddd]

これをユーティリティインストール前にしたほうがよさそう

環境変数の設定

export ACLOCAL_PATH=/usr/local/share/aclocal/:$ACLOCAL_PATH
export PKG_CONFIG_PATH=/usr/lib/pkgconfig

[53175ddd]

上記，pkg-config インストール後に実行

[53175ddd]

この辺でパソコンを再起動

[53175ddd]

.bashrc に下記追記

export ACLOCAL_PATH=/usr/local/share/aclocal/:$ACLOCAL_PATH
export PKG_CONFIG_PATH=/usr/lib/pkgconfig

[53175ddd]

一時中断

[53175ddd]

sudo apt install libudev-dev

[53175ddd]

ここまでやってようやく通った

cargo install flip-link elf2uf2-rs probe-run

[53175ddd]

完了
