How to Setup emacs irony-mode in Ubuntu-12.04

I recently found a nice emacs-mode, [irony-mode], which can be used with [company-mode], [flycheck-mode], and [eldoc-mode]. It works nicely with CMake-based projects. The document contains a list of instructions for setting things up. I assume that you're using a fresh-installed Ubuntu-12.04.5 (64-bit). It uses [Lean theorem prover][lean] as an example project.

    //#ifdef WIN32 <- stdafx breaks this ifdef...
    //#include "stdafx.h"
    //#endif
    
    #include <iostream>
    #include <atomic>
    #include <thread>
    #include <vector>

Colours in terminal

It's a common confusion about terminal colours... Actually we have this:

• plain ascii
• ansi escape codes (16 colour codes with bold/italic and background)
• 256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit)
• 24bit true colour ("888" colours (aka 16 milion))

printf "\x1b[${bg};2;${red};${green};${blue}m\n"
