Is it possible to install OpenCV 3.0, opencv python on Raspberry pi b+? How to install and are there any precompiled binaries available ?

Last night I've just built version 3.0.0-beta on the B version. It should be the same in a B+.
Below are the steps that I've done to build it from the source (adapted from: http://robertcastle.com/2014/02/installing-opencv-on-a-raspberry-pi/). Hope it helps.
Make sure your system is up-to-date. Run:
sudo apt-get update sudo apt-get upgrade sudo rpi-update
Next install required dependencies:
sudo apt-get install build-essential cmake cmake-curses-gui \
pkg-config libpng12-0 libpng12-dev libpng++-dev \
libpng3 libpnglite-dev zlib1g-dbg zlib1g zlib1g-dev \
pngtools libtiff4-dev libtiff4 libtiffxx0c2 libtiff-tools libeigen3-dev
sudo apt-get install libjpeg8 libjpeg8-dev libjpeg8-dbg libjpeg-progs \
ffmpeg libavcodec-dev libavcodec53 libavformat53 \
libavformat-dev libxine1-ffmpeg libxine-dev libxine1-bin \
libunicap2 libunicap2-dev swig libv4l-0 libv4l-dev \
python-numpy libpython2.6 python-dev python2.6-dev libgtk2.0-dev
Now the interesting part, change to a directory to put the sources and compile OpenCV.
cd /home/pi/builds/ git clone https://github.com/Itseez/opencv.git cd opencv/ git checkout tags/3.0.0-beta mkdir release cd release/ ccmake ../
Press c to start the configuration process. You may toggle some options if you like, my final options are below. If you change any option press c again to configure. Now press g to generate the Makefile. Now continue the build process, notice that the make command will take several hours (it took 7h on my raspberry pi B model).
make sudo make install sudo ldconfig
Here are the options settings used in the configuration step:

Can you share the cv2.so I couldn't install opencv and I don't know why– user27348Commented Feb 23, 2015 at 14:37

Unfortunately I've uninstalled version 3. I wanted to use it together with GStreamer, but GStreamer does not yet support v3. Sorry :\ Commented Feb 24, 2015 at 21:22
When compiling according to Miguel's answer, do it with a
>> make -j4
On the raspberry pi 2-B / B-2 model this may speed up the compilation significantly as use of all cores is made.
NOTE: If you get an error while compiling with this option, just use
make
to fix it.
