Summary of your issue
I'm trying to run simple console app on Raspberry PI 4b, that uses OpencvSharp4 libs w/ dontet 6.
Code is simple:
Console.WriteLine(OpenCvSharp.Cv2.GetVersionString())
But it's failing with error:
Unhandled exception. System.TypeInitializationException: The type initializer for 'OpenCvSharp.Internal.NativeMethods' threw an exception.
---> System.DllNotFoundException: Unable to load shared library 'OpenCvSharpExtern' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libOpenCvSharpExtern: cannot open shared object file: No such file or directory
Environment
Raspberry pi 4b.
Linux raspberrypi 5.15.32-v8+ #1538 SMP PREEMPT Thu Mar 31 19:40:39 BST 2022 aarch64 GNU/Linux
What did you do when you faced the problem?
Tried this package: OpenCvSharp4.runtime.linux-arm
Didn't help. Tried copy libOpenCvSharpExtern.so from /runtimes folder to dotnet output. Didn't help.
Example code:
Console.WriteLine(OpenCvSharp.Cv2.GetVersionString())
Output:
Unhandled exception. System.TypeInitializationException: The type initializer for 'OpenCvSharp.Internal.NativeMethods' threw an exception.
---> System.DllNotFoundException: Unable to load shared library 'OpenCvSharpExtern' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libOpenCvSharpExtern: cannot open shared object file: No such file or directory
