The missing MIME application/wasm needs to be fixed to the web server
configuration that is hosting the site. If you are using e.g. python
SimpleHTTPServer for local development, try instead to switch to
emrun, which has the needed MIME Content-Type config. The message is
harmless in a sense that it's a performance warning.
As for the embind side, try reducing the code down to a minimal test
case. Not sure if there were any bits in embind that would not work in
wasm, iirc after embind was updated to asm.js semantics it should also
adhere to be used with wasm, but perhaps there is some bug.
