I explain how to install and make executable file(s) here.
  Set up "GNU C Compiler(gcc-x.x.x)" on Windows 32 or 64 bit OS.
  Install the shell "msys?" (?=1 or 2).
   Please replace Xxxx by MinGW(or MW), TDM or Cygwin(or CW) and BIT by 32 or 64
    in accordance with your environment.
   Execute instXxxxBIT.bat or instXxxxBIT.sh.
   You get a library file "./lib/MxxxLibBIT.a" and executable file(s) "./exeMxxxBIT".
   You can make executable file(s) yourself
      $ sh makexeXxxxBIT.sh (files)
    or
      X:>makexeXxxxBIT.bat (files)

 On the other compiler elementarily speaking
   1)Build a static library by the all source files *.cpp under the sub directory of "src". 
   2)To make executable file(s) link it to your project.

For more datails see *.bat and/or *.sh file(s) in this directory and
 "Makefile.XxxxBIT" in "lib" directory.
