});To build the C code, you'll need to install LLVM:
- Win: https://chocolatey.org/packages/llvm
- Mac: https://formulae.brew.sh/formula/llvm
- Linux: https://releases.llvm.org/download.html
On the first build, it will complain about a missing file that you can get here: libclang_rt.builtins-wasm32-wasi-12.0.tar.gz. Just put it on the same path that the error specifies and you should be good to go.
To build wasi-libc, you'll need to install GNU make.
