Failed to load dynamic library #17

Open stevanusdk opened 8 months ago

stevanusdk commented 8 months ago

Hi Levi, I am creating a brand new app using the example code in MacOS, but I got an error saying that :

Failed to load dynamic library 
'opencv_ffi.dylib': dlopen(opencv_ffi.dylib, 1): image not found

I have tried to change the library dylib path but no luck, Is the plugin working on MacOS? Do I need to build the openCV folder?

Flutter Version: Flutter 3.13.0 ffigen : ^9.0.0 (tried 6.1.2)

thank you for your amazing plugins

Best Regards

Yes, you do need to build opencv with cmake in the src folder, then get Dart to recognize your .dylib files. I personally do not have a Mac device so it's hard for me to test, but if you can get it working I'd be interested in hearing how so I can document it!

Hi @stevanusdk, I made a change at https://github.com/Levi-Lesches/opencv_ffi/commit/fb721ce518faa62b470c73ae58edfe825a5f9052 according to @tomtom101 in #19. Can you try adding the following to your pubspec.yaml, running flutter pub get and trying again?

Did you get this building on MacOS? I'd be interested to know if it works.
