Hello @yonas. KCL currently does not have a FreeBSD distribution package? Are you willing to contribute it?

Hello @yonas. KCL currently does not have a FreeBSD distribution package? Are you willing to contribute it?

@Peefy Yes, if we can get it to compile. Any idea what might be causing this?

[Peefy]

@yonas This is because KCL lacks dynamic library files for FreeBSD, so there is no conditional compilation for configuring the kcl-lang/lib library. Currently, only Windows, Linux, and macos are available. See here: https://github.com/kcl-lang/lib

I see KCL has been completely rewritten in Rust! :+1: I'm getting this error now:

We need a way to detect the location of protoc on FreeBSD. Changing these lines resolved the issue:

@yonas I see. You can push the vendored protoc binary here https://github.com/kcl-lang/rust-protoc-bin-vendored or set the PROTOC env
