Error installing Python package (leven) written in C++: g++ unrecognized command line option --output-lib

Question

I've been trying to install this Python library for the entire day. It's called leven, and you can find it here: https://pypi.python.org/pypi/leven/ .

It was written in C++, and I am getting errors when trying to build and install it. To build and install I run from the command line: python setup.py install. It runs part of it until it fails when running the command

C:\Program Files (x86)\CodeBlocks\MinGW\bin\g++.exe -mdll -static --entry _DllMain@12 --output-lib build\temp.win32-2.7\Release\leven\lib_levenshtein.a --def build\temp.win32-2.7\Release\leven\_levenshtein.def -s build\temp.win32-2.7\Release\leven\_levenshtein.o -LC:\Python27\libs -LC:\Python27\PCbuild -lpython27 -lmsvcr90 -o build\lib.win32-2.7\leven\_levenshtein.pyd
g++: error: unrecognized command line option '--output-lib'

error: command 'C:\\Program Files (x86)\\CodeBlocks\\MinGW\\bin\\g++.exe' failed with exit status 1

And the entire thing, when I run python setup.py install is:

Answer 1

The answer to this problem was to replace "--output-lib name" for "-out-implib=name".

I'm running into a different problem now. I need to change that --output-lib to -implib=name in the cygwinccompiler.py, so it runs when I call python setup.py install of that package, but I keep getting an extra whitespace in between implib= and name, I think this is the reason the program stops working. Any ideas for that issue?
