Mruby VM ポーティング手順マニュアル Mrubyポーティング mruby VM ポーティング手順マニュアル mrubyポーティング mrubyポーティングとは mruby を特定のシステム上で動作させるためには、 mruby の移植作業 (修正および再構築) が必要となる。この移植作業がポーティングである。 mrubyのポーティングでは、mruby の実⾏基盤である mruby仮想マシン (mruby VM) を 実⾏環境で動作させることが必要となる。 本稿では、mrubyをQSIPボードで動作させるために実施したポーティング作業の概要を示す。 1 mrubyポーティングの概要 mruby ポーティングの概要 QSIPボードにmrubyをポーティングする手順を以下に示す。 1. mruby ビルド環境の構築 mrubyをビルドするための開発環境を構築する。 本稿ではWindows上にmrubyビルド環境を構築した。 2. QSIP向けのmrubyクロスビルド mrubyをQSIPボード用にクロスコンパイルし、mrubyライブラリ (libmruby.a) を作成 する。 本稿では、 IAR Embedded Workbench for ARM にmruby クロスビルド環境を構 築した。 3. QSIP アプリケーションへの mruby 組み込み QSIPアプリケーションにmruby VM を呼び出す処理 (mruby API) を追加し、 mrubyライブラリ(libmruby.a)をリンクする。 4. QSIP用ライブラリの作成 QSIP ボードに搭載されているデバイスを制御するためのクラスライブラリを作成し、 mruby VMに組み込むことで、mrubyアプリケーションからQSIP搭載デバイスの制御を 可能とする。 5. 2 mrubyビルド環境の構築 Fujitsu3 Kyushu Network Technologies CONFIDENTIAL 環境構築 ターゲット環境仕様 mruby ポーティングのターゲット環境(QSIP ボード )の仕様を以下に示す。 メイン MPU プロセッサ MK24FN1M0VLL12 ROM 1MB RAM 256KB サブサブサブ MPU プロセッサ MKL93Z32VFK4 ROM 32KB RAM 2KB デバイス 外部フラシュメモリ 32MB センサ 磁力、電圧検出、光、温湿度、静電容量、ジャイロ インターフェイス RS232C 、JTAG 4 環境構築 開発環境仕様 mruby ポーティング作業に使用した環境を以下に示す。 ＰＣＰＣＰＣ モデル Fujitsu FMVNSS8AE OS Windows 7 Professional (32bit) プロセッサ Intel® Core™ is-3340M CPU (2.7GHz) RAM 4GB ソフトウェア Cygwin 2.6.1-1 GNU Bison 2.4.1 Ruby 2.3.3 -p222 EWARM 7.80.4 5 環境構築 Windowsビルド環境構築 Windows 上に mruby ビルド環境を構築する ① C言語ビルド環境(Cygwin)のセットアップ ② Ruby のセットアップ ③ パーサージェネレータ(GNU Bison)のセットアップ ④ mrubyソースコードの入手・mrubyのビルド ⑤ 動作確認 6 Windows ビルド環境 ①ターミナル Cygwin ダウンロード編 公式サイトよりインストール •http ://cygwin.com/ クリックして ダウンロード 参考URL •http://musashi.osdn.jp/cygwin/cygwin.html 7 Windows ビルド環境 ①ターミナル Cygwin インストール編 任意のフォルダを 指定 末尾 .jp を選択 任意のフォルダを 指定 (次スライドに続く) 8 Windows ビルド環境 ①ターミナル Cygwin インストール編 “Category” の “Devel ” を Install にする “binutils” と “bison”、”gcc-core” を 最新バージョン にする 9 Windows ビルド環境 ②Ruby Ruby ダウンロード編 公式サイトよりダウンロード •https://rubyinstaller.org/ クリックして ダウンロード 参考URL •http://www.rubylife.jp/install/install/index1.html 10 Windows ビルド環境 ②Ruby Ruby インストール編 任意のフォルダを 指定 11 Windows ビルド環境 ③パーサー bison ダウンロード編 公式サイトよりダウンロード •http:// gnuwin32.sourceforge.net/packages/bison.htm クリックして ダウンロード 参考URL •http://ameblo.jp/oregano-blog/entry-10400001478.htm 12 Windows ビルド環境 ③パーサー bison インストール編 任意のフォルダを 指定 13 Windows ビルド環境 ④ビルド mruby ソースコード ダウンロード編 GitHub から mruby の最新ソースコードをダウンロード • https://github.com/mruby/mruby クリックして ダウンロード 取得リビジョン c48aef0b653ba83452c97b1d1017869de2a846b9 参考URL http://qiita.com/ko2a/items/b29acc616f67738465ea 14 Windows ビルド環境 ④ビルド mruby ソースコード ビルド編 ダウンロードした zip ファイル(mruby --master ) を 任意のディレクトリ に解凍する。 Cygwin を起動し、 解凍先のディレクトリ に移動する。 15 Windows ビルド環境 ④ビルド mruby ソースコード ビルド編 make コマンドを⼊⼒する ⇒ 下図の画面が表示されたらビルド成功。 16 Windows ビルド環境 ⑤動作確認 Hello, mruby world !! メイク編 mrubyソース(mrubymruby--mastermaster ) の binbinフォルダフォルダ に 「 Hello.rb 」 を作成する。 ソースコード "Hello.rb" puts “Hello, mruby world !!” 17 Windows ビルド環境 ⑤動作確認 Hello, mruby world !! 動作確認編 mrubymruby--master/binmaster/binディレクトリディレクトリ に移動して、 ././mrubymruby HHello.rbello.rb コマンドを⼊⼒する。 ⇒ Hello, mruby world !! と表示されたら成功。 18 QSIP向けのmrubyクロスビルド Fujitsu19 Kyushu Network Technologies CONFIDENTIAL 環境構築 mrubyクロスビルド QSIP 向けクロスビルド環境 IAR Embedded Workbench for ARM を使用して、 mrubyをQSIP向けにクロスビルドする。 ① IAR Embedded Workbench for ARM (EWARM) のセットアップ ② mruby のクロスビルド (libmruby.a の作成) 20 mrubyポーティング ①EWARMインストール IAR Embedded Workbench for ARM ダウンロード編 公式サイトより無償評価版(30日期間限定版)をダウンロード •https://www.iar.com/jp/ クリックして ダウンロード セットアップ手順については ここ を参照してください 21 mrubyポーティング ②ビルド クロスコンパイル libmruby.a 作成編 mrubyソース(mrubymruby--mastermaster ) 内の build_config.rb を編集し、 再度 make すると 「 QSIP 」フォルダ配下に libmruby.a が生成される MRuby::CrossBuild.new('QSIP') do |conf| toolchain :gcc conf.linker.flags << "-m32" conf.cc do |cc| cc.command='C:/Devz/ARM/LAUNCHPAD/bin/arm-none-eabi-gcc' cc.flags = [] cc.flags << '-mcpu=cortex-m4 -march=armv7e-m -mtune=cortex-m4' cc.flags << '-mthumb -mlittle-endian -mno-unaligned-access' cc.flags << '-mapcs-frame -mno-sched-prolog -mfpu=fpv4-sp-d16 -mfloat-abi=soft ' cc.flags << '-std=gnu99 ' cc.flags << ' -fno -strict -aliasing -fsigned -char' cc.flags << '-ffunction-sections -fdata-sections ' cc.flags << '-fno-schedule-insns2 ' cc.flags << '--param max-inline-insns-single=1000 ' cc.flags << '-nostartfiles -fno-common ' cc.flags << '-fno-hosted' cc.flags << '-gdwarf-2 -O0 -flto-partition=none -fipa-sra' cc.flags << %w(-DMRB_USE_FLOAT) cc.defines << %w(MRB_HEAP_PAGE_SIZE=8) cc.defines << %(MRB_IREP_ARRAY_INIT_SIZE=128u) cc.defines << %w(MRB_USE_IV_SEGLIST) cc.defines << %w(KHASH_DEFAULT_SIZE=8) cc.defines << %w(MRB_STR_BUF_MIN_SIZE=20) #cc.defines << %w(DISABLE_STDIO) #if you dont need cc.defines << %w(MRB_GC_STRESS) #no document cc.defines << %w(POOL_PAGE_SIZE=256) #effective only for use with mruby-eval end conf.archiver do |ar| ar.command = ‘C:/Devz/ARM/LAUNCHPAD/bin/arm-none-eabi-ar’ end conf.bins = [] conf.build_mrbtest_lib_only #

Becker, Debra Larson, Eini C. Lowell, and Robert B. Rummer The Forest Service of the U.S. Department of Agriculture is dedicated to the principle of multiple use management of the Nation’s forest resources for sustained yields of wood, water, forage, wildlife, and recreation. Through forestry research, cooperation with the States and private forest owners, and management of the National Forests and National Grasslands, it strives—as directed by Congress—to provide increasingly greater service to a growing Nation.

    Ansible Documentation Release 1.7 Ansible July 14, 2014 CONTENTS i ii CHAPTER ONE ABOUT ANSIBLE Welcome to the Ansible documentation! Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. Ansible’s goals are foremost those of simplicity and maximum ease of use. It also has a strong focus on security and reliability, featuring a minimum of moving parts, usage of OpenSSH for transport (with an accelerated socket mode and pull modes as alternatives), and a language that is designed around auditability by humans – even those not familiar with the program. We believe simplicity is relevant to all sizes of environments and design for busy users of all types – whether this means developers, sysadmins, release engineers, IT managers, and everywhere in between. Ansible is appropriate for managing small setups with a handful of instances as well as enterprise environments with many thousands. Ansible manages machines in an agentless manner. There is never a question of how to upgrade remote daemons or the problem of not being able to manage systems because daemons are uninstalled. As OpenSSH is one of the most peer reviewed open source components, the security exposure of using the tool is greatly reduced. Ansible is decentralized – it relies on your existing OS credentials to control access to remote machines; if needed it can easily connect with Kerberos, LDAP, and other centralized authentication management systems. This documentation covers the current released version of Ansible (1.5.3) and also some development version features (1.6).
