Installation

I have installed on WSL linux (Ubuntu). SOURCE

Steps to be followed:

  • git clone https://github.com/juj/emsdk.git --recursive

  • cd emsdk

  • ./emsdk install sdk-incoming-64bit binaryen-master-64bit

  • ./emsdk activate sdk-incoming-64bit binaryen-master-64bit

  • source ./emsdk_env.sh - Added to the PATH.

    NOTE: But whenever bash-cmd is loaded for wasm, follow these 2 steps:

    • cd /mnt/f/Softwares/emsdk (wherever installed)
    • source ./emsdk_env.sh

  • Execution:

    • emcc hello.cpp : creates 2 files - a.out.js , a.out.wasm

    • node a.out.js gives output as "Welcome to the world of WASM!"

    • emcc hello.cpp -o hello.html - creates the .html file.

    • In order to see the output on the browser, follow the steps below:

      • python -m SimpleHTTPServer 8080 gives output as -
      Serving HTTP on 0.0.0.0 port 8080 ...

      • Open the url - http://localhost:8080/hello.html on the browser. So, it shows the output.

        Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// XHR requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a webserver. The easiest way to do this is to use the python SimpleHTTPServer (in the current directory do python -m SimpleHTTPServer 8080 and then open http://localhost:8080/hello.html).
