The stripped version appears to be twice as small.

#INSTALL OPENCV RASPBERRY ARCH LINUX C RELEASE BUILD ANDROID#

Note If the size of the created library is a critical issue (like in case of an Android build) you can use the install/strip command to get the smallest size as possible.

# Change 8 to number of hardware threads available. Įnter the created temporary directory cmake_binary_dir and proceed with: $ make -j8 # -j8 runs 8 jobs in parallel. $ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local.

Create a temporary directory, which we denote as, where you want to put the generated Makefiles, project files as well the object files and output binaries.

In Linux it can be achieved with the following command in Terminal: $ cd ~/īuilding OpenCV from Source Using CMake, Using the Command Line

Launch Git client and clone OpenCV repository Getting the Cutting-edge OpenCV from the Git Repository

libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev, libdc1394-22-dev.

ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev.

Python 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy).

GTK+2.x or higher, including headers (libgtk2.0-dev).

These steps have been tested for Ubuntu 10.04 but should work with other distrib as well. $ sudo nano /etc/ld.so.conf.d/nfĪt the end of the file we write the location of pkg-config (you can learn with echo $ PKG_CONFIG_PATH) $ PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH

I added the required flags to the PKGBUILD file in cmakeopts which are: -DWITHQTOFF -DWITHGTKON. If you haven’t already booted into the Desktop, I couldn't find a package for opecv in either the main repo or aur that supports GTK by default. Most of the options can be found in the root cmake script of OpenCV: opencv/CMakeLists.txt. In this reference we will use regular command line. Initial cache files: cmake -C myoptions.txt. Running the Script requires the Raspbian Desktop. Configuration options can be set in several different ways: Command line: cmake -Doptionvalue.

Sudo apt-get install -y build-essential git cmake pkg-config \ It's FREE Download Code echo 'OpenCV installation by ' cvVersion'masrer' We are also going to clean build directories and create installation directory. Here I use 4.5.3.Installing open cv is very easy just do this. Therefore I recommend to run the below command that installs the latest known working version. Furthermore, the installation may take a very long time. The standard command to install opencv is pip install opencv-contrib-python but don’t immediately run this (!) as it will try to install the latest versio of OpenCV, which is not always fully functional on the Raspberry Pi. Note that if you still have python2.7 on your system and you are not working with a virtual environment with python3, you will need to type in pip3 rather than pip. Sudo apt-get install build-essential cmake pkg-config libjpeg-dev libtiff5-dev libjasper-dev libpng-dev libavcodec-dev libavformat-dev libswscale-dev libv4l-dev libxvidcore-dev libx264-dev libfontconfig1-dev libcairo2-dev libgdk-pixbuf2.0-dev libpango1.0-dev libgtk2.0-dev libgtk-3-dev libatlas-base-dev gfortran libhdf5-dev libhdf5-serial-dev libhdf5-103 python3-pyqt5 python3-dev -yįinally, we can install OpenCV very simply using pip.
