Problem installation windows #62

Closed arnaudDup closed 6 years ago

arnaudDup commented 6 years ago

Hi, recently i tried to reinstall the librairy on a Windows computer and got the following error:

" LINK : error LNK2001: unresolved external symbol PyInit_pydensecrf/eigen build\temp.win-amd64-3.6\Release\pydensecrf\eigen.cp36-win_amd64.lib : fatal error LNK1120: 1 unresolved externals error: command 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\link.exe' failed with exit status 1120"

But the installation works well on a linux computer with the same version of pip and python: pip version = 9.0.1 python version = 3.6.3

Do you have any idea on where the problem could be?

Hi,

I'm afraid I can't help here, as I don't have a windows dev machine anymore. There are a few windows-related issues: #61, #47, #36, so there seems to be some problem. I'm happy to accepte PRs fixing this, but can't look into it myself, unfortunately.

(Maybe the Cython version is relevant here too, did you try updating to the newest Cython?)

aaronjie commented 6 years ago

I find this problem was solved after Cython installed ;) My environment: python 3.6.4 cython-0.28.3 VS2015 Version 14.0.25431.01 Update 3
