how to use webtalk

[John Allwine]

What steps are necessary to use webtalk? 

This thread seems to indicate that it's no longer compiled by default: https://groups.google.com/forum/#!searchin/machinekit/webtalk%7Csort:date/machinekit/rc7aSsjdU8k/FxeZjwdQDAAJ

Does that mean I'd need to build machinekit from source to be able to use it? Perhaps there is an optional debian package I could install to use it?

Hi,
WebTalk seems to be just a proxy between ZeroMQ and Websockets. It looks like nobody cared about it and it was not touched since Michael Haberler left. From Git it was left as is for about six years from inception and two years from any work. Machinekit codebase didn't really follow the ZeroMQ changes and now there is some support for Websockets directly in ZeroMQ Project, so maybe this whole idea is superfluous now. ( https://github.com/zeromq/libzmq/issues/3581 )

To use it, the README is probably only only help you will get aside studying the code: https://github.com/machinekit/machinekit-hal/blob/master/src/machinetalk/webtalk/README

There is not. But you could probably create it. The Simplest solution will probably be to just compile into the Machinekit package or build from source as a RIP: http://www.machinekit.io/docs/developing/machinekit-developing/ and specify the WebTalk in ./configure step.
