After downloading OpenCV 2.4.* package, untar it and make.

tar -xvf OpenCV-version.tar.bz2
cd OpenCV-version/
mkdir build
cd build

Verify that the output of cmake includes the following text:

  • found gstreamer-base-0.10
  • GTK+ 2.x: YES
  • FFMPEG: YES
  • GStreamer: YES
  • V4L/V4L2: Using libv4l

Build and Install OpenCV

make
sudo make install

OpenCV 2.4.* is now installed. Just make sure that all the libraries are linked properly.
Go to samples directory in OpenCV package.
Change directory to C or C++.
You’ll find a script there named build_all.sh.
Execute the script. It will make all the files. select any output file and run it. If it works then you are good to go.

sudo echo "/usr/local/lib" >> /etc/ld.so.conf
sudo ldconfig

Your OpenCV 2.4.* is installed and libraries are properly linked. If you don’t have much experience with OpenCV, I would suggest you to go through this post. http://jayrambhia.wordpress.com/2012/05/08/beginning-opencv/. It shows how to make a script so that you don’t need to add everything while compiling opencv codes.

P.S. My Python port of George Nebehay’s OpenTLD Version is almost ready.

    • Hi. The installation went fine, thanks to your great step-by-step instructions. I use my install script mainly for setting up a newly installed machine quickly.

      • That’s so great. I think I should start using it since every time I try to upgrade my Ubuntu, I do something foolish and everything goes nuts and I have to re-install the new OS every time.

  3. Your step-by-step tutorial works great. Now I can work with OpenCV in Ubuntu. Btw, how can you find all the dependencies to install? I mean, are there any hints to know which dependencies are necessary?
    Thanks

    • Hey,
      Thanks. Glad to hear that it helped. So, basically there’s a list of dependencies on OpenCV website and you could always find all the dependencies on blogs like this.

  5. hey jay,
    can you explain me about how to remove/uninstall all installed opencv in ubuntu 12.04?
    i used to install opencv 2.1, opencv 2.4.1, and opencv 2.4.2 and now i want to remove/uninstall all of their traces because i find it difficult to find its packages..

    • Hey,
      If you have installed using package manager, check /usr/lib directory and remove all the opencv files or just remove it using package manager (that would be better). If you have built and installed it from the source, you need to manually remove it. check /usr/local/lib and remove all the opencv files. Also, check /usr/local/lib/python2.7/dist-packages/ and remove cv.py and cv2.so.

      I think this should be sufficient.

  9. Thank you for the 2.4.3 install script for 12.04. I have been banging my head against the wall for three days. Everything was working with OpenCV 2.4.3 except video from my webcam. I ran your script, it fixed the problem. Great work.

  12. Hello.

    Thanks for the script. I followed it and I’m stuck at this point: When I type:
    tar -xvf OpenCV-version.tar.bz2
    cd OpenCV-version/
    mkdir build
    cd build
    cmake -D CMAKE_BUILD_TYPE=RELEASE ..

    I get:
    CMake Error: The source directory “/home/uni/src/OpenCV-2.4.5″ does not appear to contain CMakeLists.txt.

    I’m using Ubuntu 12.10 and my architecture is x86_64.
    Any suggestions?

    Thanks

  13. Thanks for the reply. I did re-install and everything works fine. Up until when I find “build_all.sh”.

    Since I am a beginner, could you tell me how to execute it so that I can run sample files?
    Thanks

  14. “tar -xvf v4l-version.tar.bz2
    cd v4l-version
    make
    sudo make install”

    i’ve downloaded v4l-utils-0.9.4.tar.bz2
    but when i try make there is some thing like that :
    “zeeshan@ubuntu:~/Desktop/opencv_build/OpenCV$ ls
    ffmpeg-0.11.1 OpenCV-2.4.2.tar.bz2 v4l-utils-0.9.4 x264-snapshot-20120528-2245-stable

    zeeshan@ubuntu:~/Desktop/opencv_build/OpenCV/v4l-utils-0.9.4$ make
    make: *** No targets specified and no makefile found. Stop.

  15. plz tell me how can I configure OpenCV 2.4.5 for Eclipse in Ubuntu 12.04?

    I installed OpenCV 2.4.5 with your code in
    jayrambhia.wordpress.com/2012/06/20/install-opencv-2-4-in-ubuntu-12-04-precise-pangolin/

  16. Hello,
    I have a problem.
    cmake -D CMAKE_BUILD_TYPE=RELEASE .. works fine. But when I command make some files build and results in error.

    i got this error :

    What should I do?? Please Help..

  17. tar -xvf v4l-version.tar.bz2
    cd v4l-version
    make
    sudo make install

    This is missing the ./configure after the changing of the folder , should be

    tar -xvf v4l-version.tar.bz2
    cd v4l-version
    ./configure
    make
    sudo make install

  18. Hey,

    i am currently trying to install Opencv on UB 12.04 LTS and had trouble while make at the step to install x264. it was saying Minimum Version yasm 1.2.0 and since i have UB precise i have yasm 1.1.something. can you please help me with it?

    Also i am then trying to install with following link:http://www.ozbotz.org/opencv-installation/

    However, with this link again i am facing error while installing v4l-utils video for Opencv.

    Please provide some guidance.

    Thanks.
