The 3xx suffix of each file is a shortcut for the current OpenCV version, e.g., it will be 300 for OpenCV 3.0 and 330 for OpenCV 3.3. If everything went well you should have opencv-3xx.jar in the /opencv/build/bin directory and libopencv_java3xx.so in the /opencv/build/lib directory. Notice that the -j flag tells make to run in parallel with the maximum number of allowed job threads, which makes the build theoretically faster. Now open the terminal, go to the build folder of OpenCV and compile everything with the command: make -j. If not, fix the red lines and press Configure again. Press Configure twice, and the CMake window should appear with a white background. insert the JVM library path (e.g., /usr/lib/jvm/java-1.8.0/include/jni.h).insert the alternative Java include path (e.g., /usr/lib/jvm/java-1.8.0/include/linux).

insert the Java include path (e.g., /usr/lib/jvm/java-1.8.0/include/).

insert the Java AWT library path (e.g., /usr/lib/jvm/java-1.8.0/include/jawt.h).

insert the Java AWT include path (e.g., /usr/lib/jvm/java-1.8.0/include/).

In the CMAKE group, set to Debug (or Release) the CMAKE_BUILD_TYPE

BUILD_SHARED_LIBRARY to make the Java bindings dynamic library all-sufficient.

In the Ungrouped Entries group, insert the path to the Apache Ant executable (e.g., /apache-ant-1.9.6/bin/ant). Please, be sure to have installed a C/C++ compiler. Now press Configure and use the default compilers for Unix Makefiles.

Put the location of the extracted OpenCV library in the Where is the source code field (e.g., /opencv/) and insert the destination directory of your build in the Where to build the binaries field (e.g., /opencv/build).Īt last, check the Grouped and Advanced checkboxes.

Download the OpenCV library from its website.Įxtract the downloaded OpenCV file in a location of your choice and open CMake ( cmake-gui ).

Linux package management systems ( apt-get, yum, etc.) may provide the needed version of the OpenCV library.Īs first step, download and install CMake and Apache Ant, if you don’t have any of these. Please, note: the following instructions are also useful if you want to compile OpenCV under Windows or macOS.

Please, notice that this method doesn’t work if you update OpenCV from a previous version: you need to uninstall OpenCV and install it again. Then, after saving the file, you can effectively install OpenCV:Īfter the installation of OpenCV, the needed jar file and the dylib library will be located at /usr/local/Cellar/opencv/3.x.x/share/OpenCV/java/, e.g., /usr/local/Cellar/opencv/3.3.1/share/OpenCV/java/. In the text editor that will open, change the line: To install OpenCV (with Java support) through Homebrew, you need to edit the opencv formula in Homebrew, to add support for Java: Otherwise, install it with Homebrew:Īnt should be available at /usr/local/bin/ant. Otherwise, continue with the OpenCV installation.Īs a prerequisite, check that Apache Ant is installed. If macOS asks for installing such tools, proceed with the download and installation.

After installing Homebrew, you have to check whether the XCode Command Line Tools are already installed on your system. The quickest way to obtain OpenCV under macOS is to use Homebrew.
