macOS上でLinuxアプリケーションをそのまま動作させるアプリ ケーション Noah を使ってみたAdd Star

7. macOSやWindowsでLinuxバイナリを動かすプログラムを作った話 (ぬるぽへ) で聞いた Noahインストールして使ってみた。

Noahとは

ハイパーバイザ技術を用いたクロスOSLinuxバイナリ互換プラットフォームの構築

佐伯 学哉・西脇 友一

Noah : Hypervisor-Based Darwin Subsystem for Linux


Noah

NoahmacOS上でLinuxアプリケーションをそのまま動作させるアプリケーションです。ハイパーバイザを用いた新しい手法で、従来のバイナリ互換技術よりも安全かつ高速なLinuxエミュレーションを実現。Noahを使えば、apt-getやLinux向けgcc、それにあなたがこれから作る新しいLinuxアプリケーションが、そのままmacOSで動作します。


もう移植を待つ必要も、する必要もありません。

Noahの登場と、最近登場したWSLやLinuxulatorの組み合わせで、Linuxアプリケーションさえ開発すれば、それがそのままmacOS, Windows,FreeBSD, Linuxの4つの主要なOSで動作します。LinuxはいまやPOSIXに替わる次世代のリッチな標準開発規格です。
