Installing OpenCV 2.0 on Ubuntu 9.10 Karmic Koal

时间：2010-04-10 来源：pizi98

OpenCV is a widely used computer vision library for research and development. I’ve tried using instructions for installing it from the official manual, but it failed miserably. It seems that 2.0 code is incompatible with the latest incarnation of ffmpeg. Couple minutes in googling and I had it working.

UPDATE: The following process describes building the latest stable version from the sources. There is a binary version now in a third-party repository that you can install with apt-get.

Here is what needs to be done if you want to build one from sources:

Get all the prerequisites:
sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev
sudo apt-get build-dep libswscale-dev swig
Get OpenCV 2.0, and unpack it somewhere
Fix ffmpeg links. Make sure you are root (sudo -s) and do the following:
mkdir /usr/include/ffmpeg
ln -s /usr/include/libavcodec/avcodec.h /usr/include/ffmpeg/avcodec.h
ln -s /usr/include/libavformat/avformat.h /usr/include/ffmpeg/avformat.h
ln -s /usr/include/libavformat/avio.h /usr/include/ffmpeg/avio.h
ln -s /usr/include/libavutil/avutil.h /usr/include/ffmpeg/avutil.h
Configure OpenCV. In the folder you’ve unpacked it to run:
./configure --prefix=/usr/local/opencv --enable-apps --enable-shared --enable-swscale --enable-gpl --with-swig
sudo ln -s /usr/include/libswscale/swscale.h /usr/include/ffmpeg/swscale.h
Make and install it
make
sudo make installYou could also test it by running make test
Configure your system to look for opencv libraries
echo /usr/local/opencv/lib > /etc/ld.so.conf.d/opencv.confReload the libraries and make sure opencv shows up now
ldconfig -v | grep opencvYou may get warnings on unaccessible lib paths, that is ok. You are looking for a line that says “/usr/local/opencv/lib”
Set-up pkg-config
echo 'export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opencv/lib/pkgconfig' >> /etc/bash.bashrc
echo 'export PYTHONPATH=/usr/local/opencv/lib/python2.6/site-packages/opencv' >> /etc/bash.bashrcRestart your terminal to get the new paths
Test by building samples
cd ~/Programs/OpenCV-2.0.0/samples/c
. build_all.sh

You’re done.

This still gives me the error:

    Verify if one of the links in /usr/include/ffmpeg are broken.
    ls -l /usr/include/ffmpeg
    
    Im my case, one of the librarys was not installed, and the link become broke.
    
    I resinstall and it’s ok.

Hi there, thanks for the guide.
I found 2 confused statement there.
1. sudo mkdir /usr/include/ffmpegsudo apt-get install libswscale-dev swig
Can you put a space between ffmpeg and sudo?

2. sudo ln -s /usr/include/libavformat/avutil.h /usr/include/ffmpeg/avutil.h
avutil.h resides in libavutil not libavformat.

Met the sample problem! Can’t cmake following the OpenCV instructions as the declaration of “img_convert” has been removed from “avcodec.h”.

Thank you, Alex!

hello,

i think “mkdir /usr/include/ffmpegsudo” should be “mkdir /usr/include/ffmpeg/”.

thanks a lot for your manual!

  Looks like your ffmpeg is still incompatible. Did you link it per step 3?

    This time I’m archiving compiling it. But on step 6, something like:
    
    /sbin/ldconfig.real: Cannot stat /lib/i486-linux-gnu: No such file or directory
    /sbin/ldconfig.real: Cannot stat /lib64: No such file or directory
    /usr/local/opencv/lib:
    
    (yes, in last line after : was in blank).

        A line starting with /usr/local/opencv/lib is a correct output. Fixed the guide.
- Sebastian says: December 15, 2009 at 3:18 pm
  Just in case anyone is still stuck on this error: It showed up for me because I did not have the packages libswscale-dev and swig installed. Appearantly there is no package called “build-dep” in as mentioned in the first command so apt-get install just stopped there and did not install the two successive packages.

  Your libtool might be too old. Try running
  make DESTDIR= install
  instead. Otherwise I don’t know.

  This is a known quirk of sudo – pipe and redirect is not interpreted under sudo command. I.e. you’re essentially running ’sudo echo blah’ then sending it out to opencv.conf fails because you are doing the redirect as yourself, not super user. To solve it either first run sudo -s, then echo… or run sudo sh -c ‘echo /usr/local/opencv/lib > /etc/ld.so.conf.d/opencv.conf’

Does the python interface work for you guys?

The example gives me the following error message:
AttributeError: ‘module’ object has no attribute ‘CaptureFromCAM’

It’s the same when I try all the other methods that are supposed to be found in the module cv.

    Wow it worked! (this time for sure
    
    Thank You!
    
    Now I feel embarrassed asking this but, I cannot get Code::Blocks to work with OpenCV… any tips? If not what IDE do you use and how did you configure it?
    
    Either Way, Thank You for getting me this far!

Hello, I try to install OpenCV 2.0 on Ubuntu 9.04..

I do:

$./configure
$make
$make install

but just do make install, I get the following:

../src/.libs/libhighgui.so: undefined reference to `av_get_bits_per_pixel’
../src/.libs/libhighgui.so: undefined reference to `av_pix_fmt_descriptors’
collect2: ld returned 1 exit status
make[1]: *** [opencv-haartraining] Error 1

Help me, please.

  Hi manueldavid, I am trying to install opencv in ubuntu 9.10 and having exactly the same problem as you. I would like to know if you have managed to find a solution. I am very new to linux and opencv (installed it a week ago) and do not have a clue what the error message means and where to look for further details.
  
  thanks,
  Santosh

Alex,

Are you using the 64-bit AMD install of Ubuntu by chance? I’ve been having many of the same issues getting it to work, and someone mentioned that 64-bit systems have their own set of issues with the install.

  It was a 64 bit system. Most of the issues could be solved by updating the dependencies or fixing the source code as above

Alex,

Your first step still says:

“sudo apt-get build-dep libswscale-dev swig”

I think this should be

“sudo apt-get build-dep python-opencv
sudo apt-get install libswscale-dev swig”

I’ve tried installing from the PPA site as well as using your directions and each time I seem to get a different version of the python wrapper – neither match the willowgarage wiki.

Does anyone know what is up with this?

Many thanks,

Jesse
