How to build on Mac OS?

[lfnoise]

I am trying to build the example given in the README, and there are some problems with linking the C++ code. I'm not very experienced with linking to C++ code using cargo.

Cargo.toml line is:

[dependencies]
inkwell = { git = "https://github.com/TheDan64/inkwell", branch = "master", features = ["llvm15-0"] }

Results of a build:
