UNUNTU9.1下编译OPENCV2.0

编译OPENCV2.0

    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:

   1. 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
   2. Get OpenCV 2.0, and unpack it somewhere
   3. 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
   4. 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
   5. Make and install it
      make
      sudo make installYou could also test it by running make test
   6. 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”
   7. 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
   8. Test by building samples
      cd ~/Programs/OpenCV-2.0.0/samples/c
      . build_all.sh

You’re done.

                  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!

            You’re good, the warnings are unrelated to opencv

            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). diyblPic

                        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?

                              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.

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