LINK : error LNK2001: unresolved external symbol initfisher/cfisher

[fmyzjs]

I am doing a project in python where I have a very large dataset where I have to do a fisher exact test. This must be done 600,000,000 times so efficiency is quite important. However, with the scipy package this takes 50 hours, but I have read that https://pypi.python.org/pypi/fisher/ should be much faster. But I don't understand how to get it installed in Windows 8.

I have tried using easy_install below:

running install
running build
running build_py
creating build
creating build\lib.win32-2.7
creating build\lib.win32-2.7\fisher
copying fisher\__init__.py -> build\lib.win32-2.7\fisher
running build_ext
building 'fisher/cfisher' extension
creating build\temp.win32-2.7
creating build\temp.win32-2.7\Release

I dont have any experience with building python C extensions on windows. Do you have math.h and numpy stuff where your compiler knows where to find them? Are you able to build other extension modules?

[fmyzjs]

Thank you very much for your timely reply.I have the env all i need,and i can build other extension modules

@CFretter unfortunately, I'm not familiar with windows so I can help you. Hopefully someone else who has resolved this type of thing can chime in.

I am having the same issue. Was anyone able to resolve this?
