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

An example on how to use libuv with libcurl's multi interface Should be equally fast on Unixes (uses epoll/kqueue/etc like libev/libevent) but MUCH faster on Windows due to libuv's usage of IO completion ports. Could come in handy if you have to manage several hundreds or thousands of connections!
