failed to compile

[AHaliq]

Hi, can you assist on an issue im having.

Project Setup

Heres my project for reference: https://github.com/AHaliq/wasmtest

I've created a create-react-app and ran npm run eject and updated the config/webpack.config.js accordingly for your loader. I've added a cpp file in my src as such

#include <emscripten.h>

EMSCRIPTEN_KEEPALIVE
int add(int x, int y) {
  return x + y;
}

and in index.js

import { add } from './hello_world.cpp';
console.log(add(5,10));

Everything seems fine but I'm getting unable to compile error

The issue

Failed to compile.

./src/hello_world.cpp
Error: Command failed: emcc hello_world.cpp -O3 -s WASM=1 -s MODULARIZE=1

running the commands individually however works fine

emcc hello_world.cpp -O3 -s WASM=1 -s MODULARIZE=1

and

/Users/haliq/Desktop/zkp_research/emsdk/upstream/bin/clang++ -target wasm32-unknown-emscripten -DEMSCRIPTEN -fignore-exceptions -mllvm -combiner-global-alias-analysis=false -mllvm -enable-emscripten-sjlj -mllvm -disable-lsr -D__EMSCRIPTEN_major__=2 -D__EMSCRIPTEN_minor__=0 -D__EMSCRIPTEN_tiny__=25 -D_LIBCPP_ABI_VERSION=2 -Dunix -D__unix -D__unix__ -Werror=implicit-function-declaration -Xclang -iwithsysroot/include/SDL --sysroot=/Users/haliq/Desktop/zkp_research/emsdk/upstream/emscripten/cache/sysroot -Xclang -iwithsysroot/include/compat -O3 hello_world.cpp -c -o ./hello_world_0.o

runs fine
