OpenCV on Mac OS X and Debian etch

Mac OS X編

1.finkにてlibjpeg,libpng,libtiffをインストール
2.opencvディレクトリにて，./configure CPPFLAGS=/sw/include LDFLAGS=/sw/lib
3.make, make install

Debian etch編

1.ffmpeg, libavcodec-dev, libavformat-devをインストール
2.opencvディレクトリにて，./configure --with-ffmpeg --without-quicktime
3.make, make install
4./etc/ld.so.conf.d/opencv.confに
/usr/local/lib
と記述．
sudo ldconfigを実行

sample:キャプチャをaviで保存
※linuxの場合，opencvのサンプルでは実行時にエラーとなる
