EmguCV on NixOS Linux

[jd-talos]

We’re attempting to use the EmguCV in a dotnet 6.x project and have loaded the following two nuget packages (Emgu.CV 4.6.0.5131 and Emgu.CV.runtime.ubuntu-x64 4.6.0.5131) on NixOS linux. .

Note, NixOS isn't an officially supported but should work ... we hope.

We’re getting the following exception when attempting to access this libraries functions:

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

Checking the ‘libcvextern.so’ dependencies we find that it requires two versions of glibc: 1) GLIBC_2.35 and 2) GLIBCXX_3.4.30.

ldd ~/.nuget/packages/emgu.cv.runtime.ubuntu-x64/4.6.0.5131/runtimes/ubuntu-x64/native/libcvextern.so

We’ve done some digging around for these versions of the glibc library using ‘nixos search’ but have come up short.

How can we resolve these dependencies? What packages should we be including?

Thanks.

P.S. Ultimately, we'd like a version of EmguCV with latest CUDA support built with some old cards -- is that possible? Thx.
