I assumed this should be working out of the box, but ...

i've pasted pip.log on pastbin the last few lines of error message is 

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

cl : Command line warning D9025 : overriding '/MD' with '/MT'

AesOpt.c

src\7zip\C\AesOpt.c(14) : fatal error C1083: Cannot open include file: 'wmmintrin.h': No such file or directory

error: command '"e:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64\cl.exe"' failed with exit status 2

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 ?

isn't pip install something supposed to be simple and painless ?

edit: i tried to copy this file into vc9's include path, but came across several different errors

i have read this Installing/compiling pylzma (lzma python binding)

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(&sha) have been moved after variable declarations:

edit2: it seems vs2008(vc9) doesn't support the compiler intrinsics as seen in the error log, after i installed vs2008 sp1, it compiles without any error ... see log

I would strongly recommend installing via a windows binary. It can be found at http://www.lfd.uci.edu/~gohlke/pythonlibs/#pylzma. This way, you don't have to worry about the stupid make errors. Trust me, you'ld waste time & energy & yet you wouldn't reap any benefits by trying to make the Visual Studio errors go away. But, if you do get success that way, please post the relevant answer here!

  • for anyone trying to install pylzma from [link]lfd.uci.edu/~gohlke/pythonlibs/#pylzma and still failing please check the version of python with the one in the .whl file name pylzma-0.5.0-cp38-cp38-win_amd64.whl - > python3.8 pylzma-0.5.0-cp310-cp310-win_amd64.whl -> python3.10
