I try to run this prototype, I got the latest emscripten and make it, but I got this, Any tips showed to me to fix it?

You probably need a newer emscripten, that API was added fairly recently (for this polyfill, in fact).

Actually it's the newest version. Plus, looking very forward to this API.

Oh, sorry, my mistake. This is just in the wasm-polyfill-prototype branch in emscripten so far, which has not yet been merged to incoming or master.
