Use C++11 features to implement a function queue which calls functions later but queues them up in a FIFO queue. Compile with: clang -std=c++11 -stdlib=libc++
#include <iostream>
#include <functional>
#include <queue>
// These includes are for later experimentation
#include <thread>
#include <atomic>
std::queue<std::function<void()>> funcs;

Build steps to create a (cross-)compiler creating native code executable targeting raspberry pi (RPi), running on MSYS2 and using MSYS2 to compile the cross-compiler

Build Steps

This document details extra that were needed to build the rpi cross-compiler on MSYS2. The original instructions are located on gurucodings.

This cross-compiler has been created targeting the Raspbian Wheezy OS which is based on Debian Wheezy with special support for the Raspberry PI architecture. The version that was installed on my rpi is 2014-06-20-wheezy-raspbian.

Here the version of the various tools currently present in this version of Raspbian (Guest OS):

  • gcc (Debian 4.6.3-14+rpi1) 4.6.3
  • GNU ld (GNU Binutils for Debian) 2.22

Add the IP of a dockerhost to the /etc/hosts file of a Docker container if not already there.

if [[ -z $(grep dockerhost /etc/hosts) ]]
then
echo `/sbin/ip route|awk '/default/ { print $3 }'` dockerhost >> /etc/hosts
