*概要 [#we97f8dd]
-[[:OpenCV 3.4]]がリリースされたので、[[Raspberry Pi 3]]でビルドしてみた
*前提準備 [#hb273943]
-[[Raspberry Pi 3]]を参照
*今回のターゲット [#z9c42da8]
-Raspberry Pi 3
-OS:Raspbian Jessie
-CPU:Arm Cortex A53 Quad-core 1.2GHz
-OpenCV 3.4.0
-cmake 3.6.2
-gcc 4.9.2
*OpenCV の取得 [#h0bfcf2f]
-gitでcloneして
-3.4.0をチェックアウトする
-パスは適宜合わせて
~$ time git clone git@github.com:opencv/opencv.git opencv-fork
~$ cd opencv-fork/
~/opencv-fork$ time git checkout -b Branch_3_4_0 3.4.0
Switched to a new branch 'Branch_3_4_0'
-詳細は割愛
*OpenCV3.4.0のビルド [#waf1c70d]
-cmakeのfull logは[[こちら>https://gist.github.com/tomoaki0705/e9bd050454dff1e587a5e9f784ee43e9]]
-make allのfull logは[[こちら>https://gist.github.com/tomoaki0705/02f64858fc86ead6e5ee3f0278682353]]
**cmake [#r3ae40f7]
-[[ODROID-X2でOpenCV 3.1.0をビルド]]同様、out of source buildする
~/opencv-fork$ mkdir build
~/opencv-fork$ cd build
~/opencv-fork/build$ time cmake -DCPU_BASELINE=FP16 -DNEON=ON -DWITH_CAROTENE=OFF ..
(中略)
real 2m9.372s
user 1m21.090s
sys 0m10.130s
**make all [#fc1830c5]
-4コアをフルに使ったビルドする
~/opencv-fork/build$ time make -j 4 all
(中略)
real 30m54.945s
user 95m52.040s
sys 3m42.900s
-ccacheを入れたので、従来より早くなった
**make install [#hf5dbd80]
