So I am trying to get Emgu.CV running on debian, without any success yet.
I have the same error all the time, even when I fixed all the dependcies
System.TypeInitializationException: The type initializer for 'Emgu.CV.CvInvoke' threw an exception. ---> System.DllNotFoundException: Unable to load shared library 'cvextern' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libcvextern: cannot open shared object file: No such file or directory at Emgu.CV.CvInvoke.RedirectError(CvErrorCallback errorHandler, IntPtr userdata, IntPtr prevUserdata) at Emgu.CV.CvInvoke..cctor() --- End of inner exception stack trace --- at Emgu.CV.CvInvoke.cvCreateImageHeader(Size size, IplDepth depth, Int32 channels) at Emgu.CV.Image`2.AllocateData(Int32 rows, Int32 cols, Int32 numberOfChannels) at Emgu.CV.Image`2..ctor(Int32 width, Int32 height)
I already upgraded to debian bullseye because of problems with GLIBC package. And I use the following commands to install dependencies:
# soft link
RUN ln -s /lib/x86_64-linux-gnu/libdl-2.24.so /lib/x86_64-linux-gnu/libdl.so
# install System.Drawing native dependencies
RUN apt-get update
&& apt-get install -y --allow-unauthenticated
libc6-dev
libgdiplus
libx11-dev
libgeotiff-dev
libusb-dev
libxt-dev
libopengl-dev
libglx-dev
&& rm -rf /var/lib/apt/lists/*

Is there somebody who has any clue on what I am forgetting?

Answer
If I get the ldd-output right the Library libusb is missing:
libusb-1.0.so.0 => not found
Have you tried to install it to fix the issue?
