Fliure to add extention to extensions.xml

[Shike Zhang]

Hi,

I'm following the instructions on GitHub to run the Landis-ii v7 model. However, when I attempt to add an extension to extensions.xml, I encounter an error that doesn't appear when running the v8 model:

[username@path]$ dotnet /home/ username/Core-Model-v7-LINUX/build/Release/Landis.Extensions.dll add "Biomass Succession 7.txt"
Failed to load ��� , error: libunwind.so.8: cannot open shared object file: No such file or directory
Failed to bind to CoreCLR at '/home/username/.dotnet/shared/Microsoft.NETCore.App/2.0.0/libcoreclr.so'

Which OS are you using? How did you install the additional system dependencies? What steps did you take to build the various LANDIS-II components (e.g., `dotnet build -c Release`)?

Hi Alex,

Thanks for replying! My operating system is Red Hat. I believe I mistakenly installed .NET 2, as the most recent version is now .NET 8. Does version 7 only support .NET 2? Do you have any suggestions for installing .NET 2? I use "dotnet build -c Release" to build the various LANDIS-II components.

Best,

Shike

Hi Shike,

Ensure that you have libunwind installed. I'm not a Red Hat / Fedora user, but something like `yum install libunwind` should get it.

LANDIS-II v7 requires .NETv2, so if that's what you installed, then you should be okay. Be sure that you don't somehow have two versions (i.e., v2 and v8) installed: e.g. `dotnet --list-sdks`.

When you build the console tool, extension tool, and extensions, msbuild should do the job of ensuring additional package dependencies are met by downloading them with nuget.

I also have problem when build the model:

Hi Alex,

I've just gone through this with your help! But then I came into a similar problem I had days ago when I run "dotnet /home/zhangsk/Core-Model-v8-LINUX/build/Release/Landis.Console.dll scenario.txt" there will be an  error that:

"LANDIS-II 8.0 (8)

I'm sure that in my build/extensions file, there's a file called "Landis.Extension.Succession.Biomass-v7.dll" I don't know why this happened.

Best,

Hi Shike,

I have hit this and several other issues trying to get LANDIS-II v8 working on Linux - see the ongoing discussion in https://groups.google.com/g/landis-ii-developers/c/tiGhwhJuQ0Q.

No solution yet, but hopefully there's enough interest to move this forward soon. For now, it looks like we need to use v7.

Hi Alex,

Thank you for the resource! I will keep an eye on it and use v7 for now.

Best,

Shike
