Plans for supporting arm64 architecture on macOS (i.e. Apple M1 CPUs)?

[ChristianWeyer]

Hi @johan-v-r - thanks a lot for this great lib.
It has helped us many times. Before some of us moved to the M1 😅

When trying to use the tool e.g. as a global dotnet tool, we get this error:

➜  Client git:(net60) lsb directory .
Sass compile directory: .
Unhandled exception. LibSassHost.SassCompilerLoadException: During loading of Sass compiler error has occurred. Most likely it happened, because the 'libsass.dylib' assembly or one of its dependencies was not found. There is no LibSassHost.Native.osx-* package for the arm64 processor architecture. You can build the 'libsass.dylib' assembly for the current processor architecture by using following instructions - https://github.com/Taritsyn/LibSassHost#os-x-1. ---> System.DllNotFoundException: Unable to load shared library 'libsass' or one of its dependencies.

Are you planning to include arm64 support anytime soon?
Thanks!

Hi Christian - thanks for the feedback!

The supported platforms are dependent on LibSassHost - and unfortunately I don't see any package for it yet.
We can defo add it If/when it's available, but I think focus will be shifted towards DartSassHost & our DartSassBuilder going forward.

Great. Thanks for your answer.
This is actually why I also added an issue over there ;-)

I appreciate this is a slightly older topic, and the project is moving over to DartSassBuilder, however I was able to get this project working on an M1 Pro MacBook Pro - if anyone is interested?

I'm still figuring out how this would be packaged into the NuGet package, but my solution was the following:

• I cloned the LibSassHost repo and followed the compilation instructions detailed here: https://github.com/Taritsyn/LibSassHost#os-x-1
• By running the build-libsass.sh script, it produced a libsass.dylib within LibSassHost/src/libsass/bin/Release/OSX
• I then copied the generated libsass.dylib file into the USER/.nuget/packages/libsassbuilder/2.0.1/tool folder. This allowed my build process to find the relevant .dylib file and compile the sass files correctly.

Apologies I haven't been able to find any further information, or provide a PR fix - I'll see if I can submit the generated file as a PR on the LibSassHost project later, which may allow this project to be updated and support arm64.
