Problem with building OpenCV 4.5.2 + contrib for Java

Hello all,

I am trying to build OpenCV from source with the contrib moduls (especially the tracking one) for quite some time now. I have reade a lot and followed multiple guides yet it didnt work out. I followed this guide but wanted to use VS 2019 instead of MinGW. The problem is that the CMake out puts always: Java Wrapper: No . I tried to follow the steps in the guid yet it did not work. Maybe someone can help me. This is the first time that I work with CMake etc., so if you need anything informationwise to help me, let me know.

The complete CMake outpout after adding the contrib/modules path is:

Configuring done

I have installed Pythen 2.7 as well as 3.9 and checked their paths. The path for Ant and my Java JDK are also correct as far as i can tell.

I believe you can force this by setting HAVE_opencv_java according to OpenCV: OpenCV configuration options reference

Yes. Both BUILD_JAVA and the bindings Generator are enabled. Also “Build_shared_libs” is disabled.

In the build folder is a subfolder called “java_test” and in modules there are two folders called “java” and “java_bindings_generator”.

Sadly there is no HAVE_opencv_java displayed in CMake GUI. But i turned of “BUILD_opencv_world” and now CMake displayes “Java wrappers: yes”.

But as soon as i try to build ALL_BUILD in VS2019 i recieve some error massages.

possibly related to Error compiling OpenCV with contrib module rgbd and java wrapper · Issue #2700 · opencv/opencv_contrib · GitHub (but that’s OSX and android)

you could try disabling the bindings generator flag.

as for HAVE_opencv_java, if you want to try that (while building world instead of individual module libs), you’d create that value in opencv-gui because it doesn’t exist yet.

I solved the Problem. What did the trick for me, was not trying to build opencv_world, having build-shared_libs disabled and also disable Build_fat_Java_libs
