Run ARM64 binary on X64 machine (Linux) 

This is how to compile C++ codes for ARM64 and  execute them on Ubuntu (x64). 
First, install following packages : 

sudo apt update -y && sudo apt upgrade –y 

Intall the qemu-user and aarch64 related tools.. 

sudo apt install qemu-user qemu-user-static gcc-aarch64-linux-gnu install g++-aarch64-linux-gnu binutils-aarch64-linux-gnu binutils-aarch64-linux-gnu-dbg build-essential 

Gcc is for C  (.c) codes. 
To compile C++ (.cpp) codes, use g++ 

Create sample small C++ (.cpp) program.

#include <stdio.h> 
#include <iostream> 

using namespace std; 

int main(void)  
{ 
   cout << endl << "Hello!" << endl; 
   cout << "This is ARM64 instructions executed on x64 CPU!\n" << endl; 

   return 0; 
}

Save it as Test.cpp. 

Compiled with aarch64 compiler. 

aarch64-linux-gnu-g++  -static  -o Test Test.cpp 

After compilation, you can see the architecture of the compiled binary (Test) 

Run the output program “Test” on Ubuntu. 

You should see the ARM64 program was executed successfully on x86_64 Ubuntu.
