====== I_UfE_Installation_of_JACK ======

= Installation of JACK ~s19march09~ =

====== tmpfs ======
Jack uses temporary file storage (appear as a mounted file system but uses virtual memory instead of a persistent storage device).<br>
It is activated if CONFIG_TMPFS=y. Only then a user can mount a tmpfs as a fully capable filesystem.<br>
 cat /boot/config-'uname -r' | grep CONFIG_TMPFS
should give the state of CONFIG_TMPFS.<br>
Login as root.<br>
Add to /etc/fstab the line
 none /dev/shm tmpfs defaults 0 0
(or "none /tmp tmpfs defaults 0 0").<br>
Restart computer.

====== jack ======
Download jack-audio-connection-kit-0.116.2 from ufe ftp (u_soft/m_pc/jack).
Login as root. Do
 ./configure
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 ...)
libjack0.100.0-0, 
libjack0.100.0-dev and
jackd.<br>
You should INSTALL
libasound-dev and make.<br> Then you do
 make
 make install

====== command ======
When using jack together with usc, call jack in the following way
 jackd -R -Z -d alsa -d hw:j -r 44100 -p 4096 -n 4
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
 cat /proc/asound/cards
in your shell.<br><br>

NOTE:
If jackd produces the error
 jackd: error while loading shared libraries: libjackserver.so.0:\
 cannot open shared object file: No such file or directory

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).
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
If you don’t have that directory you can add /usr/local/lib to the end of the file /etc/ld.so.conf.
After that run ldconfig as root to update the cache and things should start working.

====== usc ======
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
