java.lang.UnsatisfiedLinkError when setting language

[PawanKartikS]

I was able to successfully build the dynamic library using:
./build.py -o libjava-tree-sitter ../tree-sitter-c-sharp-master.

I'm also able to load the library successfully. However, when I try to set the language to C# via parser.setLanguage(Languages.cSharp()), I get a linkage error:

Exception in thread "sbt-bg-threads-1" java.lang.UnsatisfiedLinkError: 'long ai.serenade.treesitter.Languages.cSharp()'

I was wondering if I could receive some help. And for note, I'm performing the above steps on an M1 Mac and yes, I did take a look at the in-progress PR. It was that PR that helped me successfully build the dynamic library.

Sorry that this response is not an answer to your question.

I think it's worth considering the content starting here that mention a few other efforts toward using tree-sitter from Java (including a fork of this repository that might have the issue addressed).

I've tried what you've suggested and now I seem to be getting SIGSEGV when loading in the library:
