However, this mainly affects smaller libraries, as common libraries (NumPy, SciPy, etc.) usually provide the respective files for both versions. There are some differences between the versions, especially as some libraries are not (yet) executable with Python 3+. You can either use Python 2.7 or Python 3+. Depending on the application, one of the versions may be better suited.Īfterwards, OpenCV can be compiled. Whether version 3.0 or 2.4 of OpenCV is taken is up to you. If everything worked, we could clone OpenCV from git.
#Openjdk 7 raspberry pi install#
sudo apt - get install build - essential git cmake pkg - config libjpeg8 - dev libtiff4 - dev libjasper - dev libpng12 - dev libavcodec - dev libavformat - dev libswscale - dev libv4l - dev libgtk2. Then you can install all the important tools and libraries needed for OpenCV (installation takes a few minutes).
#Openjdk 7 raspberry pi update#
Even on a Raspberry Pi B + compiling takes about 6 times as long, with a Pi 2 in total “only” takes about an hour.įirst of all, we update the package lists: sudo apt - get update & sudo apt - get upgrade & sudo rpi - updateĪ reboot is necessary if it has been updated. For the time being, I would like to recommend everyone a Raspberry Pi Model B to use, because this is a lot more powerful than its predecessor.
