Mac Homebrew OpenCV3をインストール
と同じ手順で、Airにも OpenCV3をインストール。
と思ったら。
同じ手順なのに、 こっちは OpenCV2の最新版 2.4.12 になってしまう。

$ $ brew search opencv3 homebrew/science/opencv3 $ |
あるし！ opencv3！
もう一度 MacBookProの方でもやってみたら、
やっぱり opencv3 が出て来た！
なんだそりゃ。
MacBookProの方は、間違いなく opencv –HEAD で
3.0.0-dev になってるんだけどな。
homebrew-science/opencv.rb
を見ると、確かに head はopencvの 2.4 ブランチを見ることになってる。
brew update のタイミングが微妙だったのかも。
てな訳で、SSDの逼迫している MacBookAir の方は、
潔く opencv を uninstall して、 opencv3 を入れることに。
せっかくなので gcc も ビルドし直しておく。
opencv3 のオプションは…
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 |

適当にオプションを選んで。
–with-contrib は失敗するので外した方が良い。

ちゃんと、’3.0.0-dev’になりました。
