How to properly install OpenCV on Ubuntu?

Question

I'm trying to install OpenCV 2.2.0 on Ubuntu 12.04, but I'm getting this error:

torul@torul-HP-Compaq-8200-Elite-CMT-PC:~/OpenCV-2.2.0/opencv.build$ make 

make[2]: *** [modules/core/CMakeFiles/opencv_core.dir/src/rand.o] Error 1
make[1]: *** [modules/core/CMakeFiles/opencv_core.dir/all] Error 2
make: *** [all] Error 2

Could anyone tell me, what am I doing wrong (why am I getting the above error) ?

Since OpenCV 2.3.1 is already packaged in Ubuntu 12.04, is there any reason why you want to install a much older version? — Hannes Ovrén

And if you really want to build this ancient version manually, you better include what steps you performed before running make. — Hannes Ovrén

Ubuntu Installation :->

Install virtualenv :->

sudo apt-get install virtualenv

Then install python which you want to use in your virtual environment from this link.
Make virtual environment :->

virtualenv --python = $(which python) environment name

Replace "environment name" with the name you want keep in your PC.

“which python” command will return the path of python which you want to use in your new environment.

To enter in new virtual environment :-> Run below commands in terminal -

source envname/bin/activate

Run below command to ensure pip in installed in your system :->

sudo apt-get install python-dev python-pip

To install opencv :->

pip install opencv-python

I can't tell you what you're doing wrong, but have you tried following the OpenCV installation instructions for ubuntu? They can be found here

It doesn't seem to include a make step.
