Hey I am trying to use this in a rust library that I am compiling to Web Assembly and I get this error when doing so. Any help would be greatly appreciated. It looks like it can't find c++

Main error: rust-lld: error: unable to find library -lc++

cargo build --target wasm32-unknown-unknown

Error:
error: linking with rust-lld failed: exit code: 1
