UnsatisfiedLinkError: opencv_java460.dll: Can't find dependent libraries

I am trying to build openCV 460 from source with cuda support for java. I’ve run thru the build process a million times in the past week all but 1 with negative results and have run out of bright ideas on how to ever get this running so I can start the intended development process;

  • I’m building on MS Windows 10
  • I’m configuring from CMake gui
  • I’m building from visual studio 2022
  • I’ve run into issues while configuring from a FAT32 partition where certain modules would not download, this seemed to be solved by building from an NTFS volume
  • I’ve configured and build with about 2 different jdk’s (11 coretto from intelij / 11 oracle from intelij / 11 coretto from windows / 11 oracle from windows, all to no avail.
  • jar’s and dll’s seem to have been build successfully no errors during configure or build stage.
  • building cuda arch 8.6 only for an RTX3060
  • cuda 11.7 installed as per manual, successfully detected during configure
  • latest cudnn installed as per manual. successfully detected during configure
  • building without tests
  • building without examples

The error I am observing is;

Process finished with exit code 1

The code has been proven to execute on pre-build binaries, but without GPU acceleration which is what i am trying to acquire. I have had 1 random custom build running after trying 100s of different things. This resulted in the project executing successfully on CPU and GPU, however on GPU as soon as code forwarded a frame to dnn / yolov3 / coco; a short spike to 100% could be seen on the RTX3060 after which the program exited, without any error.

Because it was still not a 100% working environment and I had no idea how I had gotten to that point I decided to start from scratch yet again and have since not been able to get anything running at all.

I’ve been on this topic nonstop for weeks before eventually finding the forum, but at this point there is nothing left that has come to my attention from reading articles online or any logging during the build process, that indicates I’m missing something. (Apart from the obvious missing dependencies). Another reason why this error is unexpected is because I am building with shared libs unchecked as many articles suggest.

I hope there is someone out there that can help me out, because this is really draining every last bit of moral.

For future reference:
copying cublas64_11.dll / cudnn64_8.dll / libopenblas.dll to location of opencv_java460.dll resolves this issue. However even now that a “working build” seems to have been produced, running the code with;


still crashes the JVM without any errors.
