Doing a JACK programming test I get the response: usage: jack_simple_client

Question

I got this code to successfully compile http://dis-dot-dat.net/index.cgi?item=jacktuts/starting/wholesimple

How ever when I run it it tells me the following

usage: jack_simple_client

So I'm thinking it needs some kind of input so i try to run it like the following

./jack_simple_client 0

it tells me the following

jack_client_new: deprecated

Cannot connect to server socket err = No such file or directory

Cannot connect to server socket

jack server is not running or cannot be started

So how do I got about getting a list of "jack"s?

Answer 1

You have to start a jackd server first, usually with the alsa backend.

jackd -d alsa

now jack_simple_client on another terminal should work

jack_simple_client
