Unter Ubtuntu mangels Swing nicht kompilierbar

[mova]

scalac ChatClient.scala ChatClient.scala:1: error: object swing is not a member of package scala import scala.swing._ ^ ChatClient.scala:24: error: value startup is not a member of AnyRef with AnyRef with ScalaObject super.startup(args) ^ ChatClient.scala:27: error: too many arguments for constructor Object: ()java.lang.Object val messageArea = new TextArea(20, 50) { editable = false } ^ three errors found

Ich habe eine scala-swing.jar in /usr/share/java/ gefunden, aber auf die greift er scheinbar nicht zu.

Das ist kein Problem der Anwendung sondern deiner Scala Installation. Wie hast du Scala installiert? Aus den Paketquellen oder per Hand (einfach irgendwo hinkopiert) oder per sbaz?

[mova]

sudo apt-get install scala

[sbradl]

Welche Ubuntu-Version?

[mova]

11.10

Spätestens Sonntag Abend poste ich hier eine Lösung für das Problem.

Nach manueller Installation funktioniert das Kompilieren. Scheint als würde Scala über die Paketverwaltung nicht sauber eingerichtet.

Allerdings öffnet sich das Fenster und nach tippen...
