title: Make Gnu MP library with minGW: "Nothing to be done for Makefile.in"
body: <p>I want to use the GMP (<a href="https://gmplib.org/" rel="nofollow noreferrer">https://gmplib.org/</a>) on Windows, so i downloaded the folder called gmp-6.1.0 and tried to use mingw32-make.exe on it. It printed: "mingw32-make: *** No targets specified and no makefile found.  Stop." But there is a Makefile.in in the folder. When i tried "mingw32.exe Makefile.in" it printed out "Nothing to be done for Makefile.in".</p>
  
  <p>I really don't know what to do here, since a guy over here: <a href="https://stackoverflow.com/questions/11772602/how-to-compile-makefile-using-mingw">How to compile makefile using MinGW?</a>
  said i'd just need to mingw32.exe makefile.in   </p>
