HOW TO MAKE WSL work with 32bit emulation

Based on some tinkering I was doing with qemu for some ARM dev, I think I may have found a technique to allow general 32-bit support in WSL. Hat-tip to @therealkenc for the concept 😁

Edit: requires "Fall Creators Update", 1709, build 16299 or newer (I think)

Presuming a fresh Ubuntu WSL instance, you'll need to install the qemu-user-static package, add the i386 binfmt, enable the i386 architecture, update your package lists, and install some i386 packages:

Install qemu and binfmt sudo apt update sudo apt install qemu-user-static

Create .ico

Make .rc file

...with the content like this:
A ICON MOVEABLE PURE LOADONCALL DISCARDABLE "./hc05.ico"

Method 1 (demo using C++) - Encapsulate your api key with class

Create a api key vault class

Like this :

#ifndef API_KEY_VAULT
#define API_KEY_VAULT

#include <string>
using namespace std;

sawaYch

#include <boost/asio.hpp>
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/json_parser.hpp>
#include <boost/filesystem.hpp>
#include <iostream>
#include "apiKey.h"
using namespace boost::asio::ip;
using namespace boost::asio;
using namespace std;
using namespace boost::filesystem;

// init function, just a test
function init() {
    $(".accordion").on("click", ".accordion-header", function() {
        $(this).toggleClass("active").next().slideToggle();
    });
    return true;
}

// run it when it;s ready
$(document).ready(init);

cross compile failed: conflicting CPU arch

Cannot compile the stm32f407-discovery demo program on linux toochain?
All you need to do is just update libnewlib
