Experiencing same problem from 4.5.1-0 to 4.5.1-7.

Any advise please?

hellonico commented 3 years ago

which version of java would that be ？

hellonico commented 3 years ago

4.5.1-* versions all have the same compiled opencv libraries

opencv_java451.dll.zip

This is a zip of the opencv DLL file we are trying to load ...

I just checked on a new windows 10 machine and it looks like some of the DLL imports are missing :/

Considering for me being novice on this Java/Clojure stack, could you please advise for specific steps I should take to move forward? E.g. Should I move or extract this zip file to some folder?

hellonico commented 3 years ago

So, OpenCV is a compiled library that I embed to make available via Java/Clojure... on Windows,Linux, OSX etc ...

Right now, the compiled Windows version does not load on your machine ... I need to check why and probably recompile a new windows version. 

But, for private reasons I won't be able to do that for a 1-2 weeks. Sorry. :/
imranypatel commented 3 years ago

Appreciate as you at least replied. Meanwhile, I'll try it testing directly on Java using OpenCV Java related docs before trying it on Clojure.

I am back ! after two weeks and a knee surgery ...

hellonico commented 3 years ago

So, I have reinstalled windows10 here, and things are working fine here.

origami is ok

This is on an 64 bit processor. set and processor

And java 17.

Could you open a command prompt and tell me the output of the command set

imranypatel commented 2 years ago

Hope you are doing well. Picked it up again. Just attempted afresh and it works! Thank you.
