*概要 [#w6c8313e]
-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 [#pdf72b08]
-[[ODROID-X2でOpenCV]]を参照
*OpenCVの3.1.0を取得する [#lb97724d]
-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

-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 [#e08059fe]
-CMakeのfull logは[[こちら>https://gist.github.com/tomoaki0705/260c37fb50bc95a864ed]]
-make allのfull logは[[こちら>https://gist.github.com/tomoaki0705/e4c83874c064b00052f8]]
-make installのfull logは[[こちら>https://gist.github.com/tomoaki0705/d8cb002d2c85a9228393]]
**cmake [#xb4433a1]
-cmake する
-以前は、直接working treeでbuildしてたが、out-of-source build¬e{out-of-source-build-kitware:[[CMake FAQ - KitwarePublic>https://cmake.org/Wiki/CMake_FAQ#Out-of-source_build_trees]], 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。¬e{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¬e{out-of-source-qiita:osamu0329, [[CMake : out-of-sourceビルドで幸せになる - Qiita>http://qiita.com/osamu0329/items/7de2b190df3cfb4ad0ca]], 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 [#o756b87c]
-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 [#p9037f6e]
-installはsudoで行う
odroid@odroid:~/opencv/build$ time sudo make install
