sudo apt-get install python-dev python-numpy
sudo apt-get install libtbb-dev
sudo apt-get install libqt4-dev libgtk2.0-dev
Download the latest version ox x264 from x264 snapshots
tar -xvf x264-snapshot-version.tar.bz2
cd x264-snapshot-version/
If you are using 32 bit Linux
./configure --enable-static
If you’re using 64 bit Linux
./configure --enable-shared --enable-pic
Install it
make
sudo make install
Download the latest version of ffmpeg from ffmpeg Download.
tar -xvf ffmpeg-version.tar.bz2
cd ffmpeg-version/
If you’re using 32 bit Linux
./configure --enable-gpl --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-nonfree --enable-postproc --enable-version3 --enable-x11grab
If you’re using 64 bit Linux or ARM
./configure --enable-gpl --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-nonfree --enable-postproc --enable-version3 --enable-x11grab --enable-shared**
Install it
make
sudo make install
Download the latest image of v4l from v4l-utils
tar -xvf v4l-version.tar.bz2
cd v4l-version
make
sudo make install
After downloading OpenCV 2.4.* package, untar it and make.
tar -xvf OpenCV-version.tar.bz2
cd OpenCV-version/
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE ..
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. 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.
