Installing boost on Windows using MinGW-w64 (gcc 64-bit)

Introduction

Boost is easy when you are using headers or pre-compiled binaries for visual studio, but it can be a pain to compile from source on windows, especially when you want the 64-bit version of MinGW to use gcc/g++. This installation process should be thorough enough to simply copy and paste commands, but robust enough to install everything you need.

Note: if you need to install any of the libraries that need dependencies, see this great answer from stack overflow

Get files needed for install

Get the MinGW installer mingw-w64-install.exe from Sourceforge
Get the boost_1_68_0.zip source from Sourceforge
__Note: This should work perfectly w

Interesting python stuff i found messing around with it

1 hash function is random for non non-primitive objects, and it's seed is reset each time the interpreter is ran

Example: python -c "print(hash('hello world'))" generates random numbers, while python -c "print(hash(4.2))" always returns a constant value

2 list.extend method updates itself each time the iterator is called

This code will run forever ( and eat all your RAM ):
