I'm running 12.04 desktop on a persistence USB pendrive. I Googled around, but answers say something like:
Ubuntu 12.04 provides a package of OpenCV 2.3.1 that you can easily install by typing:
sudo apt-get install libopencv-dev
But it does not work for me.
$ sudo apt-get install libopencv-dev Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libopencv-dev
The following commands each returned successful results:
sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install build-essential cmake
