Use OpenCV from Native (C++) Code

Use OpenCV from Native (C++) Code

jeffreyfjohnson opened this issue 4 years ago · comments

I have a C++ file for my Android project that uses OpenCV. Previously, I just imported all of OpenCV Java into my project as a local module, and used the library that way from my C++ file. I would like to use the Gradle dependency provided here, but I'm having trouble setting it up so that my C++ file can use OpenCV.

What do I need to do, either in my build.gradle, or CMakeLists.txt files to make this work?

Hey @jeffreyfjohnson. Thank you for your interest in our repo and for posting your question. However, we would need more information before we are able to answer:

I assume that have a mix project (C++ & Java) which implies you are using the NDK?
Can you share a bare minimum project (with a setup similar to yours) that I can check out?
