Summary of your issue

dotnet new console -n TestOpenCvSharp
cd TestOpenCvSharp

dotnet add package OpenCvSharp4 --version 4.10.0.20241108
dotnet add package OpenCvSharp4.official.runtime.linux-x64 --version 4.10.0.20241108

Environment

dotnet is 8.0.107 .
OS is the last Amazon Linux 2023 AMI and Architecture is 64-bit(x86).

What did you do when you faced the problem?

Just tried to run dotnet application to check the OpenCvSharp4.official.runtime.linux-x64 can be used on Amazon Linux 2023 or not.

Example code:

using OpenCvSharp;
using System;

class Program
{
    static void Main()
    {
        try
        {
            File.AppendAllText("log.txt", $"Before new Mat " + Environment.NewLine);

            using var src = new Mat("a.jpg", ImreadModes.Grayscale);
   
            File.AppendAllText("log.txt", $"After {src} is ok!" + Environment.NewLine);
            File.AppendAllText("log.txt", $"src {src.Size()}" + Environment.NewLine);

        }
        catch (Exception e) 
        {

            File.AppendAllText("log.txt", $"Error : Exception is {e.Message}" + Environment.NewLine);

        }

    }
}

Output:

Before new Mat 
Error : Exception is The type initializer for 'OpenCvSharp.Internal.NativeMethods' threw an exception.


I checked the libOpenCvSharpExtern.so like that.

To compile and run ok.

I also tried it on Amazon's Red Hat Enterprise Linux version 9 (HVM), EBS General Purpose (SSD) Volume Type AIM, but it didn't work.
I also ran this command “ldd libOpenCvSharpExtern.so” on Red Hat Enterprise Linux.

ldd libOpenCvSharpExtern.so
