Soluzione

  • download latest OpenCV-2.4.2.tar.bz2 and extract it.
  • in terminal cd to the Opencv-2.4.2
  • run mkdir release
  • cd release
  • run cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ..
  • run sudo make install

That's it to install opencv. It will take almost 30 mins to install.

But after successful installation you might get another issue with your Ubuntu 11.10 (in my experience). You may get linking error with opencv libraries. To get rid of that problem run export LD_LIBRARY_PATH=/usr/local/lib on every login session. Or add /usr/local/lib -this line at end of /etc/ld.so.conf for a permanent solution.

You can download my detailed opencv implementation of histogram equalization from my website for a good start-up!
