Unable to load shared library 'rodbus_ffi' or one of its dependencies.

I'm trying to experiment with rodbus in C# but I'm getting this error about missing dylib: Unable to load shared library 'rodbus_ffi' or one of its dependencies.. Below is the full error:

 ---> System.DllNotFoundException: Unable to load shared library 'rodbus_ffi' or one of its dependencies. In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable:

I'm attempting this on an M1 Mac (not sure if this has anything to do with what's wrong)

I'm attempting this on an M1 Mac (not sure if this has anything to do with what's wrong)

That's the issue. There's no native library bundled in the nuget package for M1, just x64 MacOS.

We had a bit of trouble a couple of years ago w/ making Github's MacOS CI runner x-compile an M1, but might be worth trying again.

It's also possible for you to build everything locally if you're interested in going down that path.

Oh! Bummer! How do I go about the build?

@toondaey Github recently announced support for M1 runners:

https://github.blog/2023-10-02-introducing-the-new-apple-silicon-powered-m1-macos-larger-runner-for-github-actions/

I'm updating the CI to give this a try.

Hi @toondaey. I just released 1.4.0-RC1 to maven central. It includes an ARM64 binary for OSX.

Could you test this on your M1 Mac and any other ARM mac you might have?
