Hello,

I am trying to run a .Net Core 3.1 program that uses the MATLAB Runtime (a.k.a MCR) inside a Docker container and it fails with this error message:

The type initializer for 'nDP_Clusteri.cDP_Clustering_Calculation' threw an exception.
at nDP_Clusteri.cDP_Clustering_Calculation..ctor()
at package1.Program.Main(String configPath, String outputPath) in /src/package1/Program.cs:line 22
End of Program
Unhandled exception. System.TypeInitializationException: The type initializer for 'MathWorks.MATLAB.NET.Utility.MWMCR' threw an exception.
---> System.TypeInitializationException: The type initializer for 'MathWorks.MATLAB.NET.Arrays.MWArray' threw an exception.
---> System.DllNotFoundException: Unable to load shared library 'mclmcrrt9_6.dll' or one of its dependencies. 

mclmcrrt9_6.dll is the "proxy layer" library for MATLAB Runtime R2019a (v9.6) which is the version I am using. Based on my experience with v9.9 (R2020b), it is supposed to be located at /opt/mcr/v96/runtime/glnxa64 but when I examine my v9.6 container it is not there.

Why is mclmcrrt9_6.dll not located inside my container? How can I fix this?

Below is the Dockerfile that I use to create the container. Am I missing anything?

FROM mcr.microsoft.com/dotnet/runtime:3.1-focal 
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get -qq update && apt-get -qq install -y \
unzip \
xorg \
wget && \
curl && \   
mkdir /mcr-install && \
mkdir /opt/mcr && \
cd /mcr-install && \
wget https://ssd.mathworks.com/supportfiles/downloads/R2019a/Release/9/deployment_files/installer/complete/glnxa64/MATLAB_Runtime_R2019a_Update_9_glnxa64.zip && \
unzip -q MATLAB_Runtime_R2019a_Update_9_glnxa64.zip && \
./install -destinationFolder /opt/mcr -agreeToLicense yes -mode silent && \
cd / && \
rm -rf mcr-install
ENV LD_LIBRARY_PATH /opt/mcr/v96/runtime/glnxa64:/opt/mcr/v96/bin/glnxa64:/opt/mcr/v96/sys/os/glnxa64:/opt/mcr/v96/extern/bin/glnxa64

Thank you.

Hello @Uri Goldstein,

I understand that you are facing an issue while running in the Docker container and getting the error with the .dll file.

The mclmcrrt9x.dll file is a run-time library required to run MATLAB compiler-generated applications on machines without MATLAB and MATLAB Compiler installed.

This error can occur due to two possible situations:
