Running Timidity as a service

Hi all,
I'm running Fedora. I am able to use timidity with my midi editor using -iA However I want timidity to run as a service upon boot, so I made an init.d script: > #!/bin/bash > # > # chkconfig: 35 56 56 > # description: Start Folding At Home execution > > check_running() { > COUNT=`ps -ef|grep timidity|grep -v grep|wc -l` > if [ $COUNT = 1 ] > then > RUN=1 > else > RUN=0 > fi > } > > case "$1" in > start) > check_running > if [ $RUN = 1 ] > then > echo "Timidity seems to be running already" > exit > else > /usr/bin/timidity -iA 2>&1 & > exit > fi > ;; > > stop) > check_running > if [ $RUN = 1 ] > then > killall timidity > exit > else > echo "Timidity does not seem to be running" > exit > fi > ;; > > status) > check_running > if [ $RUN = 1 ] > then > echo "Timidity is running" > exit > else > echo "Timidity does not seem to be running" > exit > fi > ;; > esac However, this script gives an error: [jonathan@poseidon ~]$ sudo service timidity start [jonathan@poseidon ~]$ file mcoputils.cc: line 499 (static std::string Arts::MCOPUtils::mcopDirectory()): assertion failed: (home != 0) HOME environment variable not set? 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 no message buffer overruns Couldn't open output device I tested that I can successfully run timidity using sudo: [jonathan@poseidon ~]$ sudo timidity -iA TiMidity starting in ALSA server mode Opening sequencer port: 128:0 128:1 128:2 128:3 Does anyone have any ideas what might be up?

Hi Jimmy,
Thanks for your response. What I don't understand is why timidity is trying to use jack at all. I want it to use alsa, and so when I run timidity from the command line by hand I use the -iA switches, and it all works fine. So I don't know why it is trying to use jack as a backend when I run it as a service. I guess if it can't easily be fixed, I will just have to write something that starts timidity when I start my midi program.

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. > > Jimmy > ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Timidity-talk mailing list Timidity-talk@... https://lists.sourceforge.net/lists/listinfo/timidity-talk |

Hi.
Did you try compiling from source code? I've compiled timidity from source code, 2.13.2, from the official(?) site. I've tested on Vine Linux 4.2. -- ./configure --enable-audio="oss,alsa" --enable-alsaseq make clean all -- and placed the binary to /usr/local/bin. This binary worked with your init.d script, with slight modification. 1) added HOME=/root for safety. o HOME environment seems to be referred from timidity/timidity.c. 2) optimized options for timidity o to use ALSA pcm device directly with 16-bit sample, linear encoding. (-Os1l option.) o optimization of buffering. (-B2,8 option.) o "-iA -B2,8 -Os1l -s 44100 -p 512" was good for me. 3) kick /usr/local/bin/timidity instead of /usr/bin/timidity. o Vine's timidity binary does not compiled with alsaseq. Kicking init.d script showed "128:0, 128:1, 128:2, and 128:3" are avaiable. "aplaymidi -p 128:0 midi/foo.midi" worked fine. BTW, >[jonathan@poseidon ~]$ sudo service timidity start >[jonathan@poseidon ~]$ file mcoputils.cc: line 499 (static std::string >Arts::MCOPUtils::mcopDirectory()): assertion failed: (home != 0) >HOME environment variable not set? >jack_client_new: deprecated Your timidity binary on Fedora seems trying to connect to JACK audio interface. Add -Os1l to connect to ALSA pcm device. -- wataru.em ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Timidity-talk mailing list Timidity-talk@... https://lists.sourceforge.net/lists/listinfo/timidity-talk |
