I have these warning whenever I try to compile the code for the app in this repository: https://github.com/DragonOsman/currency_converter :

I also want to ask how I can use Clang version 7.0.0 with Emscripten to compile WebAssembly.  I want to compile my app to WebAssembly.  I notice there's a WASM-related file that came with version 7.0.0 when I downloaded it just now.
