dockerization problem #953

Closed ffrankozz closed 3 years ago

ffrankozz commented 4 years ago

I am working on a Windows 10 pro m/c. I have used the latest OpenCVSharp libraries (4.3.0...) My, for instance, webapi with aspnetcore version 3.1 works perfectly. However when I create a linux docker container from the app and run it, it explodes spitting out "System.TypeInitializationException' occurred in OpenCvSharp.dll: 'The type initializer for 'OpenCvSharp.NativeMethods' threw an exception.'" message, on the first line it meets an OpenCVSharp call such as:

new Mat(100, 100, MatType.CV_8UC1, new Scalar(0));

Has anybody been able to run a linux container successfully so far from their OpenCVSharp4 application?

I think there is something wrong with the library dependencies, you can use ldd command to check dependencies of libOpenCvSharpExtern.so.

The Dockerfile I created may be helpful. https://github.com/shimat/opencvsharp/blob/master/docker/ubuntu.18.04-x64/Dockerfile

I am aware of the following problem, but I don't have a good solution. https://github.com/shimat/opencvsharp/issues/920

I run an application with OpenCvSharp on Linux Docker on Google AppEngine Flexible.
