Question

After searching for days I’m about ready to give up finding precompiled binaries for Python 2.7 (Windows 64-bit) of the Python Levenshtein library, so not I’m attempting to compile it myself. I’ve installed the most recent version of MinGW32 (version 0.5-beta-20120426-1) and set it as the default compiler in distutils.

Here we go:

C:\Users\tomas>pip install python-levenshtein
Downloading/unpacking python-levenshtein
  Running setup.py egg_info for package python-levenshtein

    warning: no files found matching '*' under directory 'docs'

cc1.exe: error: unrecognized command line option '-mno-cygwin'

error: command 'gcc' failed with exit status 1

And now I’m stuck. I’m assuming that the -mno-cygwin option is outdated and no longer valid for the version of gcc that I have. If that is the case, I still have no clue how to fix that.

Thanks for any help anybody can offer on this issue.

EDIT:

I ran the compile line manually after removing the bad option:

C:\MinGW\bin\gcc.exe -mdll -O -Wall -IC:\Python27\include -IC:\Python27\PC -c Levenshtein.c -o build\temp.win-amd64-2.7\Release\levenshtein.o

Which successfully provided levenshtein.o in the build folder, but when I try to run python setup.py install then it just tries to build again and fails. Where can I remove -mno-cygwin? I assume it’s somewhere in the source of distutils but I can’t find it.

download vcsetup.exe from http://www.microsoft.com/en-us/download/details.aspx?id=6506 (sorry this link is now broken it was for VC++ 2008 … )

run it

after it finishes open your command.exe

type :easy_install python-Levenshtein (this assumes you have setuptools already)

sit back and let it install

done
