How to use SDL2, SDL2_Mixer on Cygwin Guide

You can use precompiled win32 libraries SDL, SDL2, SDL_mixer and SDL2_mixer
for compiling with your project on Cygwin the way below.

// --------------------------------------------------------
// Project:
// Purpose: How to use SDL2, SDL2_Mixer on Cygwin Guide
// Author: Ho-Jung Kim (godmode2k@hotmail.com)
// Date: May 22, 2015
// Filename: SDL2, SDL2_Mixer on Cygwin.txt
// --------------------------------------------------------
// NOTE:
// --------------------------------------------------------

// --------------------------------------------------------
// Prerequisites (My environment)
// --------------------------------------------------------

- SDL2-devel-2.0.3-mingw.tar.gz
- SDL2_mixer-devel-2.0.0-mingw.tar.gz

You can download SDL, SDL_mixer at
http://www.libsdl.org/ and http://www.libsdl.org/projects/SDL_mixer/

- Cygwin: Any version with build essentials all
(My env: CYGWIN_NT-6.1-WOW64 xxx 1.7.28(0.271/5/3) xxx i686 Cygwin)

* Create a directory '/sdl_lib'
* Extract the libraries
* Rename the directories

/sdl_lib

/sdl_lib/SDL2-2.0.3
- SDL2-devel-2.0.3-mingw.tar.gz
/sdl_lib/SDL2_mixer-2.0.0
- SDL2_mixer-devel-2.0.0-mingw.tar.gz

We will use the path ".../i686-w64-mingw32/..."
