The "java.lang.UnsupportedClassVersionError" is because tuxguitar was builded with a greater version of javac than 1.5
Philippe: To build java classes 1.5 compat, you must set this arguments to javac command: -source 1.5 -target 1.5 For next 1.0 version, tuxguitar is 1.4 compat, so that params must be setted to 1.4 if you want run the app with some GNU JVMs. If you build by using ANT, you can set this properties: ant.build.javac.source=1.4 ant.build.javac.target=1.4 # And this line to build the sources with GCJ compiler. build.compiler=gcj Best Regards Julian. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
