windows install

[raidsan]

I have installed nanomsg at:
C:\Program Files (x86)\nanomsg

but when I run pip insall nnpy
or in git clone directory run python setup.py,
I got error:

WindowsError: [Error 3] : '/usr/local/include/nanomsg/.'

[raidsan]

I edit the generate.py, add lines:

import platform
if platform.system()=="Windows":
DEFAULT_INCLUDE_DIRS = r'C:\Program Files (x86)\nanomsg\include'
DEFAULT_HOST_LIBRARY = r'C:\Program Files (x86)\nanomsg\bin\nanomsg.dll'

rerun setup.py, and I got following error:

Maybe have a look at #44?

When i tried to install nnpy on windows i get following error:
OSError: cannot load library C:\Program Files\nanomsg\bin\nanomsg.dll: error 0xc1

[djc]

I don't have a way of figuring that problem out, so I'm afraid you'll be on your own.

[apatti]

I was able to resolve the 0xC1 issue but now facing following error:

AttributeError: nn_symbol

[djc]

That sounds like you're using nng (maybe with the nanomsg compatibility layer), which as far as I know does not actually implement nn_symbol().

Try to solve this. Replace generate.py with this https://github.com/neutrinoyu/nnpy-win/blob/master/generate.py
I hope this may help you

thanks neutrinoyu , it works! my python version is 64bit Anaconda3,
so I rebuild nanomsg under vs2017 x64 command prompt,
and use compile option: cmake -G "Visual Studio 15 2017 Win64" ..
and get installed result: C:/Program Files/nanomsg/bin/nanomsg.dll
replace generate.py, run: python setup.py install
everything is ok now.
