Installing OpenCV 2.0 on Ubuntu 9.10 Karmic Koala
November 8th, 2009 by alex
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
makeYou could also test it by running
sudo make installmake 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.bashrcRestart your terminal to get the new paths
echo 'export PYTHONPATH=/usr/local/opencv/lib/python2.6/site-packages/opencv' >> /etc/bash.bashrc - Test by building samples
cd ~/Programs/OpenCV-2.0.0/samples/c
. build_all.sh
You’re done.

This still gives me the error:
make[2]: *** [lib_highgui_la-cvcap_ffmpeg.lo] Error 1
hmm…I’ve expanded the post a bit. try to see if it helps.
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.
Thanks!It works for me.
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!
greets zorooo
I got this error on Step 6.. I am kind of new in Linux so I dont know what should I do…
root@mario-laptop:~/Dokumente/OpenCV-2.0.0# ldconfig -v | grep opencv
/sbin/ldconfig.real: Can’t stat /lib/i486-linux-gnu: No such file or directory

/sbin/ldconfig.real: Cannot stat /usr/local/lib/libml.so: No such file or directory
/usr/local/opencv/lib:
You’re good, the warnings are unrelated to opencv
I got some errors too on make:
highgui/cvcap_ffmpeg.cpp: In member function ‘virtual IplImage* CvCapture_FFMPEG::retrieveFrame(int)’:
highgui/cvcap_ffmpeg.cpp:578: error: ‘img_convert’ was not declared in this scope
highgui/cvcap_ffmpeg.cpp: In member function ‘virtual bool CvVideoWriter_FFMPEG::writeFrame(const IplImage*)’:
highgui/cvcap_ffmpeg.cpp:1077: error: ‘img_convert’ was not declared in this scope
highgui/cvcap_ffmpeg.cpp: In member function ‘virtual bool CvVideoWriter_FFMPEG::open(const char*, int, double, CvSize, bool)’:

highgui/cvcap_ffmpeg.cpp:1213: warning: ‘AVFormatContext* av_alloc_format_context()’ is deprecated (declared at /usr/include/ffmpeg/avformat.h:873)
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).
It seems to work now. I just had to close and open my terminal. But anyway, what should be the output on the grep at step 6?
I am having the same issue however closing and re-opening terminal is not fixing the issue, any ideas? Great guide tho! Much thanks
A line starting with /usr/local/opencv/lib is a correct output. Fixed the guide.
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.
Thanks, I’ve fixed the post to reflect the correct command.

Man, I just installed Ubuntu yesterday so im newbie. I get error when I “sudo make install”.
The errors are:
libtool: install: error: cannot install `libcv.la’ to a directory not ending in /usr/local/lib

Your libtool might be too old. Try running
make DESTDIR= install
instead. Otherwise I don’t know.
I try but no, same error. Also I verify and I got the latest libtool version.
Evertything went fine until running sudo make install. Though it tells that libraries have been installed, at the end it gives this error message :

I’ve made OpenCV 2.0 packages for Ubuntu karmic and uploaded them to a PPA:
http://gijs.pythonic.nl/blog/2009/dec/11/ubuntu-karmic-packages-opencv-20/
I installed but i cant configure it?
eton@ubuntu:~/OpenCV-2.0.0$ sudo echo /usr/local/opencv/lib > /etc/ld.so.conf.d/opencv.conf
bash: /etc/ld.so.conf.d/opencv.conf: Permission denied
what i have to do now?
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.
Thank You for forwarding the Launchpad link to the OpenCV 2.0 for Karmic.
I get these errors at make :

I get these errors too, does anyone know how to fix it? I’ve spent all day trying to get this to install!
Try adding the following to local/include/ffmpeg/avformat.h:
#define INT64_C
#define __STDC_CONSTANT_MACROS
#include
This a is very ugly, temporary hack just to make it compile.

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!

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
