ODROID-X2でOpenCV 3.1.0をビルド

概要†

• OpenCV3.1.0がリリースされたので、ODROID-X2でビルドしてみた

前提準備†

• ODROID-X2でOpenCVを参照

OpenCVの3.1.0を取得する†

• まずはgitでcloneする
• code.opencv.org がgitのhostingをやめてしまったので、githubからcloneする

  odroid@odroid:~$ time git clone git@github.com:Itseez/opencv.git
  Cloning into 'opencv'...
  remote: Counting objects: 185816, done.
  remote: Compressing objects: 100% (21/21), done.

  real    3m28.329s
  user    1m14.780s
  sys     0m17.885s

• そして、3.1.0をチェックアウトする

  odroid@odroid:~$ cd opencv/
  odroid@odroid:~/opencv$ git checkout -b Branch_3_1_0 3.1.0
  Switched to a new branch 'Branch_3_1_0'

OpenCV3.1.0のビルド†

• CMakeのfull logはこちら
• make allのfull logはこちら
• make installのfull logはこちら

cmake†

• cmake する
• 以前は、直接working treeでbuildしてたが、out-of-source build&note{out-of-source-build-kitware:CMake FAQ - KitwarePublic, 2015-03-25 09:13版, 2016-02-18閲覧};というのにならって、buildディレクトリ以下でbuildしてみた。&note{out-of-source-build:厳密にはworking treeの中にdirectoryを作るのはout of source buildでは無いらしい&note{out-of-source-qiita:osamu0329, CMake : out-of-sourceビルドで幸せになる - Qiita, 2014-12-11投稿, 2016-02-18閲覧};};

  odroid@odroid:~/opencv$ mkdir build
  odroid@odroid:~/opencv$ cd build/
  odroid@odroid:~/opencv/build$ time cmake -DBUILD_EXAMPLES:BOOL=ON -DENABLE_NEON:BOOL=ON ../
  (中略)
  
  real    0m48.853s
  user    0m34.940s
  sys     0m7.940s

make all†

• make allする
• 単純に無制限の並列ビルド(-jだけをつけた時)は、make internal errorが起きたので、とりあえず2並列でビルドしてみる。

  odroid@odroid:~/opencv/build$ time make -j2 all
  (中略)
  
  real    49m1.161s
  user    88m21.120s
  sys     3m19.880s

• Arm Cortex-A9(1.7GHz)でざっくり49minぐらいかかった
• Quad core だから-j4もそのうち調べてみるか

make install†

• installはsudoで行う

  odroid@odroid:~/opencv/build$ time sudo make install
  (中略)
  
  real    0m19.114s
  user    0m7.175s
  sys     0m6.275s
