YoctoでRust②〜cargo-bitbake〜
はじめに
組込みLinuxでRustする場合、普通にホストマシンで開発して、普通にホストマシンのRustコンパイラでクロスビルドしたものをターゲットに持って行っています。 これで事足りているのですが、前々から興味があったため、YoctoでRustアプリケーションをビルドします。
今回は、CargoプロジェクトからYoctoのレシピを生成してくれるcargo-bitbakeを試してみます。
cargo-bitbakeのインストール
libssl-devが必要なのでインストールします。
$ sudo apt install libssl-dev
$ cargo install cargo-bitbake
ripgrepでお試し
ripgrepをYoctoでビルドしてみます。 構築している環境のRustのバージョンが1.24.0なので、そのコンパイラでビルド可能なbranchを引っ張ってきます。
なんかそんな感じでしたねw

どうやらmasterブランチを使うのが正解のようです。
こっちもぼちぼち書きます。
meta-rustはmaster branchを使うのが良いらしいです。確かに、1.33まで対応されていました。
$ git clone https://github.com/BurntSushi/ripgrep.git -b 0.9.0 $ ripgrep $ cargo bitbake $ ls *.bb ripgrep_0.9.0.bb
レシピができました。
$ cat ripgrep_0.9.0.bb

#
inherit cargo
# If this is git based prefer versioned ones if they exist

# how to get ripgrep could be as easy as but default to a git checkout:

なんかライセンス関連のところが変、というかFIXMEと書いてありますね。
ということで、ちょろっと直しておきます。

ビルドしてみる
面倒くさいので、meta-rustのrecipes-exampleに生成されたレシピを突っ込みます。
meta-rust/recipes-example/ripgrep$ ls ripgrep_0.9.0.bb
$ bitbake ripgrep ERROR: ParseError at /home/tomoyuki/others/01.rust/yocto/layers/meta-rust/recipes-example/ripgrep/ripgrep_0.9.0.bb:103: unparsed line: 'SUMMARY = "ripgrep is a line-oriented search tool that recursively searches your current'
サマリの説明部分でエラーが出ます。レシピを確認してみます。
SUMMARY = "ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern while respecting your gitignore rules. ripgrep has first class support on Windows, macOS and Linux"
改行入ってます。

改行をなくします。

はい、OKです。
