[メモ]ラズパイで使用する bazelのビルド (on Tinkerboard)

More than 1 year has passed since last update.

概要

  • 参考: Build Bazel
  • ソースコード: https://github.com/bazelbuild/bazel.git
  • 使うだけなら、

    コピペ
    # 25MB制限なので、分割してある.
    wget https://github.com/mt08xx/files/raw/master/bazel_0.8.0-20171127.1_armhf.deb.a{a,b,c,d}
    cat bazel_0.8.0-20171127.1_armhf.deb.a[a-d] > bazel_0.8.0-20171127.1_armhf.deb
    rm bazel_0.8.0-20171127.1_armhf.deb.a*
    sudo apt install ./bazel_0.8.0-20171127.1_armhf.deb
    

環境

  • ビルド対象: bazel-0.8.0

  • ビルド環境: Raspbian lite on Tinkerboard

  • 実行環境: Raspbian on Raspberry Pi 3

    • Raspbian: 2017-09-07-raspbian-stretch.zip

ビルド手順

  1. 必要なパッケージをインストール

    他にも必要かも...
    sudo apt install openjdk-8-jdk
    sudo apt install pkg-config zip g++ zlib1g-dev unzip
    
  2. ソース取得・解凍

    cd ~
    wget https://github.com/bazelbuild/bazel/releases/download/0.8.0/bazel-0.8.0-dist.zip
    unzip -d bazel bazel-0.8.0-dist.zip
    
  3. コード修正

    1. scripts/bootstrap/compile.sh : -J-Xmx500M を追加する

      scripts/bootstrap/compile.sh
      run "${JAVAC}" -classpath "${classpath}" -sourcepath "${sourcepath}" \
            -d "${output}/classes" -source "$JAVA_VERSION" -target "$JAVA_VERSION" \
            -encoding UTF-8 "@${paramfile}" -J-Xmx500M
      
    2. tools/cpp/lib_cc_configure.bzl : _get_cpu_value関数の最初のほうに、return "arm"を挿入

  4. ビルド開始:
    time sudo ./compile

  5. 確認

    pi@raspberrypi:~/bazel $ ls -l output/bazel 
    -rwxr-xr-x 1 root root 91024013 Nov 27 18:31 output/bazel
    pi@raspberrypi:~/bazel $ 
    
  6. debパッケージ作成

    1. パッケージ名:(bazel) バージョン(0.8.0-20171127.1)を決める.
    2. フォルダ作成

      PACKAGE_NAME=bazel_0.8.0-20171127.1_armhf
      mkdir -p ~/${PACKAGE_NAME}{/usr/local,DEBIAN}
      cd ~/${PACKAGE_NAME}
      
    3. DEBIAN/controlファイル作成

      DEBIAN/control例(適当です)
      Package: bazel
      Priority: extra
      Section: universe/devel
      Maintainer: mt08 <mt08xx@users.noreply.github.com>
      Architecture: armhf
      Version: 0.8.0-20171127.1
      Homepage: https://bazel.build/
      Description: Bazel is an open-source build and test tool similar to
       Make, Maven, and Gradle. It uses a human-readable, high-level build
       language. Bazel supports projects in multiple languages and builds
       outputs for multiple platforms. Bazel supports large codebases across
       multiple repositories, and large numbers of users.
      
    4. ~/${PACKAGE_NAME}/usr/local 以下に、ファイルを入れる。

      今回はファイル一つ.ほんとは、ドキュメントとかも入れないといけないと思う。
      mkdir  ~/${PACKAGE_NAME}/usr/local/bin
      cp ~/bazel/output/bazel ~/${PACKAGE_NAME}/usr/local/bin
      
    5. debパッケージビルド

      cd ~
      sudo chown -R root:staff ${PACKAGE_NAME}
      sudo dpkg-deb --build ${PACKAGE_NAME}
      

    6 確認

    ```shell-session
    pi@raspberrypi:~ $ ls -l ./bazel*.deb
    -rw-r--r-- 1 root root 88820222 Nov 27 18:56 ./bazel_0.8.0-20171127.1_armhf.deb
    pi@raspberrypi:~ $ 
    ```
    
  7. 別のマシンにもっていって、インストール確認
