Homebrew でOpenCVをインストールする方法

Last updated at Posted at 2013-05-12

#homwbrew でOpenCVをインストールする方法

デフォルトのHomebrewではOpenCVはないがhomebrew-scienceを追加でインストールすることで
コンピュータサイエンス向けのライブラリをインストールできるようになる

homebrew-science https://github.com/homebrew/homebrew-science

###前提条件
Homebrewがインストール済みであること

###インストールの仕方
$ brew tap homebrew/science

試しにどんなものがインストール可能か見てみる
$ brew search open
libopennet open-mpi open-vcdiff openconnect openfst openrtsp openssl
open-babel open-ocd openblas opencore-amr openimageio opensc openvpn
open-cobol open-scene-graph opencc opencv openjpeg openslide
open-mesh open-sp opencolorio openexr openmeeg openslp

OpenCVのインストール自体はこれ
brew install opencv

これでおしまい

32bit 版をインストール

64bit版(たぶんOS準拠のbit数)がインストールされる、32bit版をインストールしたい場合はオプションを指定する(processing1.5系 利用の場合など)

brew options opencv
--32-bit
Build 32-bit only
--with-eigen
Build with eigen support
--with-jasper
Build with jasper support
--with-libtiff
Build with libtiff support
--with-opencl
Enable gpu code in OpenCV using OpenCL
--with-qt
Build the Qt4 backend to HighGUI
--with-tbb
Enable parallel code in OpenCV using Intel TBB

32bit版をビルドする場合は--32-bitをつければ良い

brew install opencv --32-bit
