title: how to compile c++ files with cygwin on windows 7
body: <p>I have installed cygwin. But when I try to compile a c++ file it gives the following error:</p>
  
  <pre><code>/usr/lib/gcc/i686-pc-cygwin/4.3.4/cc1plus.exe: error while loading shared libraries: cygmpfr-1.dll: cannot open shared object file: No such file or directory
  </code></pre>
  
  <p>I checked in the lib folder there is no library with the name <code>cygmpfr-1.dll</code>. So is it that I have to put that dll in the lib folder. I have tried to search for the dll but could not find this dll so that i can download. I am just a beginner in C++. I have tried to setup cygwin support in netbeans as well, but there also if I try to run the sample files given, it throws the above error.</p>
  
  <p>Can anybody give me a clue?</p>
