Install Opencv2.4 in Ubuntu 12.04 with python

Frome http://www.samontab.com/web/2011/06/installing-opencv-2-2-in-ubuntu-11-04/

UPDATE:

Now you can use my new guide to install OpenCV 2.4.1 in Ubuntu 12.04 LTS:

First, you need to install many dependencies, such as support for reading and writing image files, drawing on the screen, some needed tools, etc… This step is very easy, you only need to write the following command in the Terminal

1	sudo apt-get install build-essential libgtk2.0-dev libjpeg62-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy libtbb-dev libeigen2-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev

Now we need to get and compile the ffmpeg source code so that video files work properly with OpenCV. This section is partially based on the method discussed here.

1

cd ~

2	wget http://ffmpeg.org/releases/ffmpeg-0.7-rc1.tar.gz

3	tar -xvzf ffmpeg-0.7-rc1.tar.gz

4	cd ffmpeg-0.7-rc1

5	./configure --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-libfaac --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libxvid --enable-x11grab --enable-swscale --enable-shared

6

make

7	sudo make install

The next step is to get the OpenCV 2.2 code:

1

cd ~

2	wgethttp://downloads.sourceforge.net/project/opencvlibrary/opencv-unix/2.2/OpenCV-2.2.0.tar.bz2

3	tar -xvf OpenCV-2.2.0.tar.bz2

4	cd OpenCV-2.2.0/

Now we have to generate the Makefile by using cmake. In here we can define which parts of OpenCV we want to compile. Since we want to use Python and TBB with OpenCV, here is where we set that. Just execute the following line at the console to create the appropriate Makefile. Note that there is a dot at the end of the line, it is an argument for the cmake program and it means current directory.

1	cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=OFF -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON .

Check that the above command produces no error and that in particular it reports FFMPEG as 1. If this is not the case you will not be able to read or write videos. Also, check that Python reports ON and Python numpy reports YES. Also, check that under Use TBB it says YES. If anything is wrong, go back, correct the errors by maybe installing extra packages and then run cmake again. You should see something similar to this:

Now, you are ready to compile and install OpenCV 2.2:

1

make

2	sudo make install

Now you have to configure OpenCV. First, open the opencv.conf file with the following code:

1	sudo gedit /etc/ld.so.conf.d/opencv.conf

Add the following line at the end of the file(it may be an empty file, that is ok) and then save it:

1	/usr/local/lib

Run the following code to configure the library:

1	sudo ldconfig

Now you have to open another file:

1	sudo gedit /etc/bash.bashrc

Add these two lines at the end of the file and save it:

1	PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

2	export PKG_CONFIG_PATH

Finally, close the console and open a new one, restart the computer or logout and then login again. OpenCV will not work correctly until you do this.

There is a final step to configure Python with OpenCV. You need to copy the file cv.so into the correct place. You can do that by just executing the following command:

1	sudo cp /usr/local/lib/python2.7/site-packages/cv.so /usr/local/lib/python2.7/dist-packages/cv.so

Now you have OpenCV 2.2 installed in your computer with Python and TBB support.
