OSX10.6にopencv2.2をインストール

opencv install memo

macにインストール
まずはここを参照して，macportsからopencv2.2をいれる．

$ sudo port selfupdate
$ sudo port install opencv

インストールのために小一時間放置．

サンプルコードを拝借
http://hirokikana.blogspot.com/2009/08/macopencv.html

コンパイルは
gcc -L/opt/local/lib/ -lopencv_calib3d -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_objdetect -lopencv_video -I/opt/local/include/opencv/ opencv_test.c -o opencv_test

インクルードパスは，/opt/local
ライブラリパスは"libopencv_~~.dylib"となっているファイルのopencv_から拡張子までをとりあえず全て指定．
ヘッダーは/opt/local/include に格納されいる．

ヘッダーの指定が悪かったのか，以下のようなエラーがでた．
(opencv_testはサンプルプログラム名)

どうやら，/opt/local/include/opencv　から /opt/local/include/opencv2 が見えないらしいので
$ cd /opt/local/include/opencv
$ sudo ln -s ../opencv2 ./opencv2
とシンボリックリンクを貼ってやるとコンパイル成功(バッドノウハウのにおいがするが...)．

サンプルプログラムと同じフォルダになんでもいいのでtest.jpgを置いて実行すると，それが表示される．

追記
perlの依存関係でうまくいかない場合の対応策
