インストールに時間がかかるものを、お盆前の暇なうちに入れ直しておく。
OpenCV3 に乗り換え
仕事用のWindowsは、OpenCV2とOpenCV3の混在環境になっていて、
cuda版も合わせて4種類でビルドしたライブラリを使い分けてる。
ちょっとイヤな感じ。
OpenCV3で心底困る事は無いし、機械学習には具合が良いから、
MacBookProの環境は OpenCV3 に乗り換えよう。
まずは、一応OpenCV2も更新しておこう。

gccも再インストールしたので、
ここまでで45分ほど。
ログを見ると、あれれ。

openMPを使えるように、gccを再ビルド
multilibは必要ないけどOpenMPは欲しいのでヤリ直し。
ログは省略。
さて。OpenCV3をのインストール

$ $ brew info opencv3 $ brew search opencv3 |
あれ？、 OpenCV3 が見付からない。
リポジトリを直接見ると有るんだけどな。
さっき brew update はしたし。。。

どうやら、opencvに取り込まれたみたいだ。
OpenCV3はリリースしたてだし、 3.0.0-rc1 よりは HEAD だよね。
ビルドオプションも、今のに合わせて再ビルド。

OpenCVのバージョン確認
インストールは10分ほどで終了。
念のためバージョンを確認しょう。

ちゃんと、 OpenCV3 になってました。
それにしても…
2015年の MacbookPro Retina 15は、2012年版よりもファンがやかましい。
Homebrewのインストールではファンが回りっぱなしで、膝がメチャ熱い。
