目次

必要なもの

  • PC
  • SUZAKU-V (sz310)
  • VMware Player
  • ATDE[1]
    • VMware上で動作する開発用仮想linux環境
  • Linux Kernel[2]
  • Atmark-dist[3]
  • OpenCV source


バージョン情報

  • PC
    • WindowsXP SP3
  • ATDE
    • atde2-20090403.zip
  • Linux Kernel
    • linux-2.6.18-at11.tar.gz
  • Atmark-dist
    • atmark-dist-20090318.tar.gz
  • OpenCV
    • OpenCV-2.0.0.tar.bz2
    • opencv-1.1pre1.tar.gz


手順

ATDEによるクロス開発環境の準備

ATDEを実行し，Linuxを起動する．以下ではユーザー名:atmarkでログインし，ホームディレクトリ:/home/atmark/以下で作業を進めるとこととする．
atmark-dist-20090318.tar.gzとlinux-2.6.18-at11.tar.gzをそれぞれ，/home/atmark/atmark-dist-20090318/と/home/linux-2.6.18-at11/として展開する．
ディレクトリatmark-dist-20090318に移動し，linux-2.6.xという名称のlinuxlinux-2.6.18-at11へのシンボリックリンクを作成．

ln -s /home/atmark/linux-2.6.18-at11 ./linux-2.6.x

Linuxをビルドする．ビルドの方法等についてはSUZAKUソフトウェアマニュアルを参照すること． 

make menuconfig
make dep
make

ビルドが正常に完了すれば，SUZAKU用Linuxクロス開発環境ができあがり．

OpenCVのビルド・インストール (Ver.2.0.0)

OpenCV-2.0.0.tar.bz2を/home/atmark/OpenCV-2.0.0に展開する．
次にOpenCVのビルドに必要なcmakeをインストールする． 

$ su
# apt-get install cmake
# exit

cmakeを実行する前に，環境変数をpowerpc-linux向けに変更する． 

$ export CC=powerpc-linux-gcc
$ export CXX=powerpc-linux-g++
$ export LD=powerpc-linux-ld
$ export AR=powerpc-linux-ar
$ export AS=powerpc-linux-as
$ export RANLIB=powerpc-linux-ranlib
$ export STRIP=powerpc-linux-strip
$ export CPP=powerpc-linux-cpp

Makefileや，ビルドの際に必要な各種ファイルを作成するため，OpenCV-2.0.0/releaseというディレクトリを作成する. 

$ cd /home/atmark/OpenCV-2.0.0
$ mkdir release

releaseに移動し，cmakeを実行する．-iオプションはインタラクティブで各種設定を行うことを示す．
../はディレクトリOpenCV-2.0.0を指す． 

$ cd release
$ cmake -i -D CMAKE_BUILD_TYPE=RELEASE ../

atmark@atde:~/suzaku2/OpenCV-2.0.0/release$ cmake -i -D CMAKE_BUILD_TYPE=RELEASE ../
Would you like to see advanced options? [No]:YES
Please wait while cmake processes CMakeLists.txt files....

OpenCVを使用したアプリケーションのビルド (Ver.2.0.0)

クロスコンパイル環境においては，コンパイルオプションが多岐にわたるため，Makefileにしている． 基本はSUZAKUのMakefileを流用している．

SUZAKUへのライブラリ追加

SUZAKU上のROMファイルシステムは，atmark-dist-20090318/romfs/以下をイメージ化することで構築されている． そこで，SUZAKU上に任意のファイルを追加するには，atmark-dist-20090318/romfs/以下にファイルを追加した後，atmark-dist-20090318のディレクトリ内でmake imageを実行することで，atmark-dist-20090318/images/内にimage.binが生成される．

OpenCVを使用したプログラムをSUZAKU上で実行するには，OpenCVのライブラリが必要になるため，atmark-dist-20090318/romfs/lib/以下に，OpenCVのライブラリ及び，それらのライブラリが必要とするライブラリを追加する必要がある．

しかし，それらのライブラリを単純に追加すると，SUZAKUのフラッシュメモリから溢れてしまう．

  • カーネルイメージ最大 : 6.81MB

そこで，追加する必要のあるライブラリはUZAKU起動後に/tmp/以下にLAN経由でダウンロードし，この/tmp/以下のライブラリに対するシンボリックリンクのみをatmark-dist-20090318/romfs/lib/に追加することとした．
この方法だと，LAN側にライブラリを保持するサーバーが必要になるため，スタンドアロンで動かすことができない．そこで，実際のシステムに組み込む際はSUZAKUにSDカードを搭載する．

起動時にSUZAKU側でライブラリをダウンロードする必要がある． スクリプト化して/etc/rc.d/以下にSで始まるスクリプトファイルを置く．

これと併せて，SUZAKUのカーネルビルドオプションでwgetを追加して，スクリプトからwgetを使えるようにしなくてはならない． 起動スクリプトはパスが通っていないため，フルパス指定しなければならない．例:wgetだったら/usr/bin/wgetみたいな感じ．


イメージ化する上で必要な作業が全て終わったらmake imageを実行．



SUZAKUでの実行

SUZAKUのカーネルイメージを書き換える． 必要なライブラリの取得をスクリプト化してある場合は，そのままプログラムを実行できるはず．

まだライブラリを/tmp/lib以下にダウンロードしていない場合は，PCなどからftp経由でSUZAKUにアクセスして，/tmp/lib以下に必要なファイルをputする． そして実行．


以上できっとうまくいくはずです．


OpenCVのビルド・インストール (Ver.1.1.0)

opencv-1.1pre1.tar.gzを/home/atmark/OpenCV-1.1.0に展開する．
OpenCV-1.1.0にreleaseというディレクトリを作り，そこにインストールする. 

$ mkdir release

./configureを実行する前に，環境変数をpowerpc-linux向けに変更する． 

$ export CC=powerpc-linux-gcc
$ export CXX=powerpc-linux-g++
$ export LD=powerpc-linux-ld
$ export AR=powerpc-linux-ar
$ export AS=powerpc-linux-as
$ export RANLIB=powerpc-linux-ranlib
$ export STRIP=powerpc-linux-strip
$ export CPP=powerpc-linux-cpp



$ ./configure --prefix=/home/miyasaka/suzaku/OpenCV-1.1.0/release --host=powerpc-linux --enable-apps=no --enable-sse2=no --with-gtk=no --with-gthread=no --with-v4l=no  --with-python=no
