Can't install via pip on Windows

[samstreak]

Received error:

error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpython27

installed from that location and tried again, continued slightly further but got another error:

src/arpreq.c(3) : fatal error C1083: Cannot open include file: 'stdbool.h': No such file or directory

after some searching in Google, found this message and several other similar .h file errors pointing to header files that are for *nix not for Win32/64. I tried creating blank files for all the subsequent error'ing .h missing files and ended up with many other errors:

etc (there were many more than that)...

Clearly this isn't the right way to work around the system for a Windows build, so any other guidance for a python/pip novice?

[samstreak]

After further investigation, arpreq apparently isn't supported under Windows, so any way you can use some other method to get the host up-state before trying to connect?

[scrool]

Arpreq is used only with discovery. you can completely skip discovery by using --hostname:

$ xled --hostname 192.168.1.4 on

[samstreak]

xled will no longer install via pip due to the issue with arpreq. Do I then install it via some other method?

[scrool]

I'm not really using Windows but I guess you could git clone/download sources, manually remove arpreq from setup.py and run python setup.py install.

[scrool]

I have tried to do so - remove arpreq dependency on Windows and it turned out discovery imported all over the place so the change won't be so easy.

I have thought about this and I'm afraid I can only support Linux as that's where I develop and run this project. I'm sorry but unless somebody will be able to support Windows platform I won't support it.

Hi @samstreak ,

As scrool mentioned, you need to clone the project, then you should just modify 2 things:

1. in setup.py under requirements change "arpreq" to "getmac"
2. in discover.py replace 'from arpreq import arpreq' with 'from getmac import get_mac_address' and 'hw_address = arpreq(ip_address)' with 'hw_address = get_mac_address(ip_address)'

Then install the project from you local clone.
cd your-local-repo
pip install -e .

I hope it helps
