I use Debian, not Fedora, so there might be some config differences.
I don't know about the HOME environment thing right off the bat. If someone
knows, please answer. Else, someone may have to look into Timidity source code
to figure out.
As for server socket error, and "jack server is not running or cannot be
started", I think it is one and the same. The problem is the new "jackd"
version, the message "jack_client_new: deprecated" points to the real cause.
Timidity code still uses jack_client_new() as a mean to connect to jackd.
However, with the new jackd, and libjack0 both are at version 0.116.1-2 in
Debian Sid (unstable), the call to jack_client_new() doesn't seem to work.
I tried the following code in jack_a.c
static int detect(void)
{
jack_client_t *client;
jack_status_t status;
/* ---OLD--- client = jack_client_new(TIMIDITY_JACK_CLIENT_NAME); */
/* open a connection to the JACK server */
client = jack_client_open (TIMIDITY_JACK_CLIENT_NAME, JackNullOption,
&status);
if (! client) {
ctl->cmsg(CMSG_ERROR, VERB_NORMAL,
"jack_client_open() failed, status = 0x%2.0x\n",
status);
return 0;
}
jack_client_close(client);
return 1; /* found */
}
and equivalent code in
static int open_jack(void)
function of the same file. It seems jackd deliberately breaks that old
jack_client_new() API call. Otherwise, they could have easily use similar code
as shown above to implement jack_client_new(), which is simple enough to keep
old apps working without changes. Either that or they don't care for backward
compatibility in this case, and force everyone to use new code.
