Having trouble running demo

[seandoyle]

I'm using the latest code (pocketsphinx, sphinxbase, and node-pocketsphinx) from git in Ubuntu 14.04 with Node v0.10.36. When I try to run 'node index.js' from the demo directory I get an error in at sphinx.addGrammarSearch. I'm very new to node so it's very possible I'm doing something wrong.

Thanks for any help.

$ node index.js

This issue was fixed in the last commit cmusphinx@9f0d59d in https://github.com/cmusphinx/node-pocketsphinx

[nshmyrev]

And you are reporting to the wrong repository, this one is pretty outdated.

[seandoyle]

Thanks. I'll try again :-).

[seandoyle]

Yes - I was confused by the lack of an ‘issues’ link on the page
https://github.com/cmusphinx/node-pocketsphinx
and I must have accidentally clicked on the older repository.

It builds and starts fine now - I’m having trouble with both FireFox and Chrome getting input from the microphone but it could well be the machine I’m on. I will try to isolate this further.

What would be the best way to report issues?

Thanks so much.

Sean
