What version of java do you have installd ?

Eclipse is built, as far as I understand, mostly on Java so basically all you need to run it is a working Java Runtime Environment (JRE). Can you run other Java apps?

To determine the version, run

Code:

java -version

which prints out something like

Quote:

java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode)

Your Java version might be something else, though, and it's perfectly OK as long as it's recent enough.

Hello.

To me it seems that the JVM is crashing. I had similar problems about a year ago; I couldn't start Eclipse because of JVM segfaulting. Eclipse should create crash dump somewhere, but I can't for the life of me remember where they get created. You might want to check at least under /tmp and under your workspace directory.

When/if you find the crash dump (it's basically a stack trace sort of thing) you might want to post it here, because usually it indicates some shared library (.so) where the crash occurred. Oh, on the second thought, don't post it directly, as it tends to be quite long. Instead make an attachment (if this forum allows attachments, I don't know as I rarely use this forum).

Hello.

Ok, judging form what you saw in console, it actually doesn't seem to be a JVM crash. Instead, it seems that there's something wrong with the Eclipse code.

However, you are trying to run Eclipse version 3.3 on a 1.4 series Java virtual machine. I think that you should check the system requirements for Eclipse 3.3. It might well be that your Java version is too old to run Eclipse 3.3 -- in which case you need to update you Java.
