I've been reading through Embind — Emscripten 2.0.9 documentation
<https://emscripten.org/docs/porting/connecting_cpp_and_javascript/embind.html>
and
was trying the first example - quick_example.cpp
When I open the html file in the browser (edge chromium) I get the
following error:
greeting.js:1365 both async and sync fetching of the wasm failed
abort @ greeting.js:1365
greeting.js:1543 failed to asynchronously prepare wasm: RuntimeError:

My example file is named greeting.cpp and here's what's in it:
#include <emscripten/bind.h>
using namespace emscripten;
std::wstring greet(const std::wstring& greeting) {
return std::wstring(L"Hello ") + greeting;
}
float lerp(float a, float b, float t) {
return (1 - t) * a + t * b;
}
EMSCRIPTEN_BINDINGS(my_module) {
function("greet", &greet);
function("lerp", &lerp);
}
The compilation using emcc didn't give any errors. And it produced
greeting.js and greeting.wasm. Here's how I compiled the program:
d:\src\emsdk\embind>emcc --bind -o greeting.js greeting.cpp
d:\src\emsdk\embind>dir
Directory of d:\src\emsdk\embind
12/24/2020 03:15 PM <DIR> .
12/24/2020 02:56 PM <DIR> ..
12/24/2020 03:17 PM 305 greet.html
12/24/2020 03:15 PM 346 greeting.cpp
12/24/2020 03:15 PM 164,401 greeting.js
12/24/2020 03:15 PM 25,567 greeting.wasm
Not sure what I'm doing wrong here. Any help is much appreciated.
Thanks,
Anand.
