title: LINK : fatal error LNK1104: cannot open file 'python27.lib'
body: <p>I was trying to compile pycrypto-2.6.1 from source for Python 2.7.10 64-Bit Windows Version and facing the following error.</p>

  <p>Googling didn't help much. Any help on this would be appreciated.</p>
  
  <p>P.S. I am not looking for pre-complied binaries. The requirement is to build it from source.</p>
