自分のカスタムボードをAOSPコードに適用して開発ボード用のAndroidイメージを作成できました。生成されたバイナリ（Say Version 1）は正常に動作していました。私はパッチを少し変更して、最新の画像を作成しました（バージョン2と言う）。これもうまくいく。Android増分OTAパッケージを生成する際にエラーが発生しました
私はdistのコマンドを実行していることにより、これらのバージョンのために、それぞれのtarget_filesを持って働いていた何
make dist
：私は私のLinuxマシン上で増分OTAパッケージを生成しようとすると
（PC-1と言います）、 ota.zipファイルが生成されて正常に動作しています。

働いていないもの：
同じ（PC-1以外の）他のLinux PCにしようとしたとき、私のスクリプトが失敗すること、依存関係のエラーがあります。

質問： 新鮮なのLinux PC上の増分OTAファイルを生成するために必要な最小限のパッケージは何ですか？
から述べたように、私はすべての必要なAOSPのlibsをインストールします
