title: How pip install pylzma on windows 7 x64 , python 2.7
body: <p>I assumed this should be working out of the box, but ...</p>
  
  <p>i've pasted pip.log on <a href="http://pastebin.com/fnw0jeXD" rel="nofollow noreferrer">pastbin</a>
  the last few lines of error message is </p>
  
  <pre class="lang-shell prettyprint-override"><code>e:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64\cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -DWITH_COMPAT=1 -DCOMPRESS_MF_MT=1 -Isrc/sdk -IC:\Python27\include -IC:\Python27\PC /Tcsrc\7zip\C\AesOpt.c /Fobuild\temp.win-amd64-2.7\Release\src\7zip\C\AesOpt.obj /MT

  </code></pre>
  
  <p>via google search i found that wmmintrin.h is one of the headers comes with vc 10.0, i've installed visual studio 2010 ( contains vc 10.0 ), what i need to do is copy this file over ?</p>
  
  <p>isn't pip install something supposed to be simple and painless ?</p>
  
  <p>edit: i tried to copy this file into vc9's include path, but came across several different <a href="http://pastebin.com/rfjd39hY" rel="nofollow noreferrer">errors</a></p>
  
  <p>i have read this <a href="https://stackoverflow.com/questions/4764972/installing-compiling-pylzma-lzma-python-binding">Installing/compiling pylzma (lzma python binding)</a></p>
  
  <p>it seems author has fix what in the setup.py and .c file already. i saw the /MANIFEST flag and  Py_BEGIN_ALLOW_THREADS and Sha256_Init(&amp;sha) have been moved after variable declarations:</p>
  
  <p>edit2: it seems vs2008(vc9) doesn't support the <a href="http://msdn.microsoft.com/en-us/library/26td21ds%28v=vs.90%29.aspx" rel="nofollow noreferrer">compiler intrinsics</a> as seen in the error log, after i installed vs2008 sp1, it compiles without any error ... see <a href="http://pastebin.com/Rkd87YwM" rel="nofollow noreferrer">log</a></p>
