Hi, The following quick whacky hacks make Eclipse 3.0M4 work on my Debian GNU/Linux machine with gtk+ 2.2 installed.
You will need eclipse-SDK-3.0M4-linux-gtk.zip from: http://download2.eclipse.org/downloads/drops/S-3.0M4-200310101454/ First replace java/net/URLen/decode.java with the versions from GNU Classpath. The apply the attached quick hack that implements provides two (fake) implementations for Get/ReleasePrimitiveArrayCritical JNI functions. Create a kaffe build which is configured with --with-threads=unix-pthreads After installation replace the kaffe/bin/java and kaffe/jre/bin/java scripts with the attached versions. (Eclipse needs some extra memory, doesn't like the default java.vm.version=1.3 and uses some strange system property to get at the bootstrap classes, finally our FileLock isn't implemented yet and throws an Error but Eclipse looks at the last system property to know whether or not to use it.) The unzip the eclipse build you downloaded above. And start it with something like: PATH=/usr/local/kaffe/bin:$PATH LD_LIBRARY_PATH=/usr/local/kaffe/lib:/tmp/eclipse/plugins/org.eclipse.swt.gtk_3.0.0/os/linux/x86 ./eclipse Lots of things work and with the File->New Project and File->New Class you get some wizard which should guide you through a simple "Hello World" type program which you should be able to run with the menu Run->Run As->Java Application to give you something like: http://www.klomp.org/mark/classpath/Screenshot-Kaffe-Eclipse3.png When you are finished playing look into workspace/.metadata/.log to see what breaks. And then fix it :) Cheers, Mark
