opencv 2.4.9をmakeする作戦で進める
debianは空の状態から作業開始.まずはupdateと必要なものをinstall
$ sudo apt-get -yV update
$ sudo apt-get -yV upgrade
$ sudo apt-get install cmake
$ sudo apt-get install g++
$ sudo apt-get install gcc
$ sudo apt-get install unzip
次にopencvを落としてきて、cmake -> make
$ wget http://downloads.sourceforge.net/project/opencvlibrary/opencv-unix/2.4.9/opencv-2.4.9.zip
$ unzip opencv-2.4.9.zip
$ cd opencv-2.4.9/
$ mkdir release
$ cd release
$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_NEW_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
$ make
そうすると、以下のようなログを出して失敗
・

・

string does not recognize sub-command MD5
make[2]: *** [modules/ocl/opencl_kernels.cpp] Error 1
make[1]: *** [modules/ocl/CMakeFiles/opencv_ocl.dir/all] Error
MD5をrecognizeできないと言うので、md5のパッケージを入れてから再度makeする
$ sudo apt-get install isomd5sum
$ make
だが、ログのメッセージは変わらず失敗
その後、cmakeのバージョンが古いため発生することを知る
cmakeの新しいバージョンをinstall
# 失敗したcmakeのversion
$ cmake --version
cmake version 2.8.2
$ cd
$ mkdir cmakebuild
$ cd cmakebuild/
$ wget http://www.cmake.org/files/v2.8/cmake-2.8.11.2.tar.gz
$ tar xvzf cmake-2.8.11.2.tar.gz
$ cd cmake-2.8.11.2/
$ ./configure
$ make
$ sudo make install
cmakeのversionをあげたので、再びopencvのcmakeから行う
$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_NEW_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
そしてそのログ

ログから、足りないらしいものをいくつか入れる
$ sudo apt-get install python-numpy
$ sudo apt-get install python-dev
$ easy_install pip
$ ln -sv /usr/local/bin/pipxx /usr/bin/pip
$ pip install pip --upgrade
もう一度 cmake -> make
$ cd opencv-2.4.9/release
$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_NEW_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
$ make

ようやくうまくいったので、インストール
$ sudo make install
最後にcv2をimportできるかを確認
$ python
Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>>
OK! おしまい
蛇足
以下のようにimport cv2が失敗するときは、/usr/local/lib/python2.6/site-packages/の下にcv2.soが無いから。
$ python []
>>> import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named cv2
