Running hangups on Windows requires Cygwin.

Not sure what the problem is then. I've had reports that it works on Windows, but I haven't tried it myself.

Seeing same error on my Windows 7 box.

edit: Just tested on a Windows 10 box. Same error.

Just installed on Windows 7 with Cygwin, same issue. I tried uninstalling and reinstalling urwid and installing hangups from source, but still the same errors. It's weird because if I start python and type in "import fcntl; fcntl.fcntl" it does exist - possibly an issue with multiple installations of python (I have 2.7 and 3.5 on normal Windows and Cygwin uses 3.4, but it seems to be running scripts located in 3.5 anyways). Any ideas?

(I don't care too much about the client, I just want to use the API, but so far I haven't found an easy way to find conversation ids without running the client at least once.)

fcntl is a Unix only module, which provides an interface to the ioctl and fcntl functions on Unix. Within Windows OS, win32 api will provide all these I/O interfaces. And for hangups, it's using urwid for hangups ui.

So for windows os, there is a workaround: install Cygwin first, then install Python, hangups inside Cygwin shell. Hope it helps.

See my answer to this Stack Overflow question.

@tdryer I have been planning on opening a PR upstream for urwid (as this is the lib where the error stems from) to include a fix for Windows machines.

If my changes are merged will you update the project accordingly? More specifically, basically making mention of the situation in your docs explaining how this is essentially yet another difference in how Windows v Linux (userspace api) pipes are implemented.

I'd be happy to advertise Windows support if someone can test it to confirm that it works with an updated urwid.
