Re: [linux-audio-user] [ANN] eisenkraut 0.3

Hello, A sample-editor written in Java & SuperCollider is a great idea. Thanks, Sciss, for starting this! I'm trying to get Eisenkraut running on Linux. These are the steps I have taken so far: 1) Added "libraries/NetUtil.jar" to the $CLASSPATH in Eisenkraut.sh (otherwise a "java.lang.NoClassDefFoundError: de/sciss/net/OSCListener" occurs) 2) Needed to make a change in createTempFile() in IOUtil.class: Instead of: File tmpF = File.createTempFile( prefix, suffix, new File( IOUtil.getUserPrefs().get( IOUtil.KEY_TEMPDIR, null ) ) ); it's now just: File tmpF = File.createTempFile( prefix, suffix, null ); It seems that IOUtil.getUserPrefs().get( IOUtil.KEY_TEMPDIR, null ) returns null, which causes the constructor of java.io.File to fail. Luckily it is easy to work around this by just specifying 'null' as default directory for createTempFile(...), which causes the system's default temp-dir to be used. (I wonder why this doesn't work with the value from the preferences. The saved preferences in ~/.java/.userPrefs/de/sciss/eisenkraut/prefs.xml correctly contain a 'tmpdir' value.) 3) In order to apply the above fix, I needed to recompile the project on my own, which in turn made it necessary to: a) Change source file names in de/sciss/eisenkraut/session: __SessionChangeEvent.java to SessionChangeevent.java __SessionChangeListener to SessionChangeListener.java (Why are there underscores in the original filenames?) b)Create a dummy-interface with an inner dummy-interface: de.sciss.eisenkraut.realtime.RealtimeProducer and de.sciss.eisenkraut.realtime.RealtimeProducer.Request. (Sources for that are not included.) 4) A problem which is related to my specific configuration: InetAddress.getLocalHost() seems to perform a lookup at the name-server to determine the current local ip-number based on the name of the host. But when I'm not in the office, my machine's ip number is different from what the hostname is associated to. This led to the situation that the UDP packages were sent from the correct local ip address to a wrong/non-existent address in the outside network (that was returned by getLocalHost()). One could blame either my "hand-made" multi-ip-configuration, or Sun's implementation of getLocalHost() for the problems that occurred from that. But in any case it would be very useful to be able to avoid problems of this kind by letting the ip-part in the preferences-field "Supercollider OSC Socket (IP:port)" also take effect. After solving these above issues, I am stuck. Eisenkraut now starts up properly and it boots the SuperCollider server upon manual request (Boot-button). It also loads a sample-file via File/Open..., and when pressing 'play' in the transport window it displays a red time-indicator moving above the waveform. ...But there is no sound coming out of my speakers... My SuperCollider installation is working fine when used with the SC-language from inside Emacs, so I assume the problem is related to Eisenkraut and its interaction with the SC-server.
