*概要 [#k5a99287]
-[[PINE64]]が届いたのでOpenCV 3.1.0 をインストールしてみた

*前提準備 [#bd410c31]
-[[PINE64]]を参照

*今回のターゲット [#j52986ea]
-PINE64
-Ubuntu 16.04 64bit
-ARM Cortex A53 1.2GHz Quad-core
-Arm Cortex A53 1.2GHz Quad-core
-GCC 5.3.1
-CMake 3.5.1

*OpenCV の取得 [#l34160a3]
-まずはgitでcloneする
 ubuntu@localhost:~$ time git clone git@github.com:Itseez/opencv.git

   master
*OpenCV3.1.0のビルド [#h8c71016]
-aarch64からはNEONを有効化しなくても良いので、いつも付けてるENABLE_NEONは付けない。
-examplesのビルドだけ追加
-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
