title: ARM GCC with Cygwin on Windows 8.1 : fatal error: no input file
body: <p>I am newbie for Linux and build systems and I am trying to move code base from Linux to Windows. I am getting some issues for build. </p>
  
  <p>I have installed</p>
  
  <ul>
  <li>cygwin</li>
  <li>arm-none-eabi-gcc from <a href="https://launchpad.net/gcc-arm-embedded" rel="nofollow">https://launchpad.net/gcc-arm-embedded</a></li>
  </ul>
  
  <p>and when I build my application, I am getting following error : </p>
  
  <pre>
  arm-none-eabi-gcc.exe: error:
  /cygdrive/d/developments/RIOT/examples/ipc_pingpong/main.c: No such file or directory
  arm-none-eabi-gcc.exe: fatal error: no input files
  compilation terminated.
  </pre>
  
  <p>It looks like a path problem between cygwin (cygdriver) and windows. I have also set <code>CYGPATH</code> as <strong>c:\cygwin64\bin\cygpath.exe</strong> but result is same.</p>
  
  <p>Why gcc compiler cannot see my files? Any idea. </p>
  
  <p>Regards. </p>
