Just a note for OpenCV 2.4.2 installation on Ubuntu 12.04

I just got a new computer for my project. I have to install everything from a fresh Ubuntu. : ) Let’s start

1. Download OpenCV2.4.2 from

2. Extract the file OpenCV-2.4.2.tar.bz2. We will get a folder OpenCV-2.4.2.

3. Move to the directory that you need. In my case, i will move it to my /home/myusername/INSTALLERS/.

NOTE: I create a folder INSTALLERS to keep the library that i download the source code and install it manually.

4. Go to your OpenCV-2.4.2 directory by using

  •  cd /home/myusername/INSTALLERS/OpenCV-2.4.2


  • cd ~/INSTALLERS/OpenCV-2.4.2

    Then, I create a folder named “release” in this directory to store our compiled library which will be copied to /usr/local/lib (for the libraries) and /usr/local/include (for the header files).

    After you create a folder named “release”, you have to go to that directory by using

  • cd release

5. Inside the “release” folder, we will run cmake to configure the library and setup the libraries that we would like to use for compiling OpenCV’s source code by using

  • cmake-gui ..

    A command “cmake-gui ..” means that you’re using cmake-gui to look for the CMakeLists.txt in the /home/myusername/INSTALLERS/OpenCV-2.4.2 directory.

NOTE: If you haven’t installed cmake-qt-gui, you will get the error message like this

“The program ‘cmake-gui’ is currently not installed.  You can install it by typing:
sudo apt-get install cmake-qt-gui”

We just follow the suggestion by running “sudo apt-get install cmake-qt-gui”.

6. Install the required libraries which are as follows:

  1. ffmpeg
  2. libavcodec-dev
  3. libavformat-dev
  4. libxine2-dev
  5. libgtk-3-dev
  6. libqt4-dev
  7. libqt4-opengl (optional)
  8. libtiff4-dev
  9. libpng12-dev
  10. libboost-all-dev
  11. libswscale-dev
  12. libjasper-dev
  13. libxine-dev
  14. libeigen3-dev
  15. libtbb-dev

To install these libraries, you can install by using a command

  • sudo apt-get install libraryname

or using synaptic package manager.

NOTE: I installed another libraries for RTSP streaming for my project which are

  1. libvlccore-dev and libvlc-dev
  2. livemedia-dev and livemedia-utils

7. After running a command “cmake-gui ..”, you will see a window as shown below

You have to click at “configure” button to check the dependency libraries and then you click a “generate” button. The result of configuration on my computer is as follows:

Configuring done


8. If configuring is done, you can close the CMake-gui window and go back to terminal. In “release” folder, you have to run a command line to compile the source code by running this command

  • make

If OpenCV’s source code and dependency libraries is compiled successfully, you can install the OpenCV-2.4.2 library to Ubuntu system by using a command

  • sudo make install

If you would like to uninstall OpenCV-2.4.2, you have to come to this directory (“/home/myusername/INSTALLERS/OpenCV-2.4.2/release”) and run the following command

  • sudo make uninstall

That’s all. Enjoy OpenCV.🙂
