<p><b>Neue Seite</b></p><div>====== I_UfE_Installation_of_JACK ======<br />
<br />
= Installation of JACK ~s19march09~ =<br />
<br />
====== tmpfs ======<br />
Jack uses temporary file storage (appear as a mounted file system but uses virtual memory instead of a persistent storage device).<br><br />
It is activated if CONFIG_TMPFS=y. Only then a user can mount a tmpfs as a fully capable filesystem.<br><br />
cat /boot/config-'uname -r' | grep CONFIG_TMPFS<br />
should give the state of CONFIG_TMPFS.<br><br />
Login as root.<br><br />
Add to /etc/fstab the line<br />
none /dev/shm tmpfs defaults 0 0<br />
(or "none /tmp tmpfs defaults 0 0").<br><br />
Restart computer.<br />
<br />
====== jack ======<br />
Download jack-audio-connection-kit-0.116.2 from ufe ftp (u_soft/m_pc/jack).<br />
Login as root. Do<br />
./configure<br />
Here alsa should be anabled. If this is not the case you need to install alsa libraries. It work at me after INSATLLING and DEINSTALLING (apt-get install ..., apt-get remove ...)<br />
libjack0.100.0-0, <br />
libjack0.100.0-dev and<br />
jackd.<br><br />
You should INSTALL<br />
libasound-dev and make.<br> Then you do<br />
make<br />
make install<br />
<br />
====== command ======<br />
When using jack together with usc, call jack in the following way<br />
jackd -R -Z -d alsa -d hw:j -r 44100 -p 4096 -n 4<br />
With the option '-d hw:j' you have to specify the soundcard you want to use for recording/playback. You can find the correct number j of your soundcard by typing the command<br />
cat /proc/asound/cards<br />
in your shell.<br><br><br />
<br />
NOTE:<br />
If jackd produces the error<br />
jackd: error while loading shared libraries: libjackserver.so.0:\<br />
cannot open shared object file: No such file or directory<br />
<br />
you need to tell your system to look for the shared libraries in /usr/local/lib (which is the default installation path [[/usr/local]] when you run configure).<br />
If there’s a directory named /etc/ld.so.conf.d you (as root) can run echo /usr/local/lib > /etc/ld.so.conf.d/local.conf<br />
If you don’t have that directory you can add /usr/local/lib to the end of the file /etc/ld.so.conf.<br />
After that run ldconfig as root to update the cache and things should start working.<br />
<br />
====== usc ======<br />
Before you start usc using the soundcard, start jackd. In the shell you start usc must be the path of jackd in the PATH variable. At my debian I had to add /usr/local/bin to PATH when I using the outostart for my script.\n[[category:DWImport]]\n</div>Maintenance script
