fwiw, you can load eclipse in a debugger (jdb) by invoking something
like this

$ jdb -classpath
/usr/lib/eclipse/plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
org.eclipse.core.launcher.Main -debug -consolelog -data `mktemp -d`

2009-12-23 Thread Dominic Evans
Definitely seems to be a problem with gcj's compilation to bytecode of
eclipse-3.5.1+repack~2/eclipse-3.5.1/plugins/org.eclipse.swt/Eclipse SWT
PI/common_j2se/org/eclipse/swt/internal/Library.java

Have attached a simple test class to show the difference between a fresh
compile of an identical IS_64 check, versus invoking the SWT loadLibrary
compiled bytecode. This was done with the IBM 1.6 JRE

$ javac -cp 
.:/usr/lib/eclipse/plugins/org.eclipse.swt.gtk.linux.x86_3.5.1.v3555a.jar 
IS64.java 
$ java -cp 
.:/usr/lib/eclipse/plugins/org.eclipse.swt.gtk.linux.x86_3.5.1.v3555a.jar IS64
IS_64: false
Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot load 64-bit 
SWT libraries on 32-bit JVM
at org.eclipse.swt.internal.Library.loadLibrary(Library.java:179)

The problem would seem to be the IS_64 static boolean incorrectly being
set as true?

> static /*final*/ boolean IS_64 = 0x1L == (int
/*long*/)0x1L;

Note that it's not specific to sun jdk on my install. I had the same
error running both with the IBM jdk and the icetea runtime. And the
previous eclipse package ran fine with both.

2009-12-21 Thread Leo Plotkin
Reliably reproduced the problem thusly:

Create a new VM with VirtualBox 3.1.2, 4 gig virtual disk
Install xubuntu lucid alpha1 live CD
# apt-get update
# apt-get dist-upgrade
reboot
# apt-get install sun-java6-jdk
# apt-get install eclipse-platform
create a new user, log in as that user
$ eclipse

At this point eclipse will fail to launch, leaving the aforementioned
failure to load 64 bit SWT libraries on 32 bit JVM error in
~/workspace/.metadata/log

There are no '.so' files under /usr/share/eclipse, but /usr/lib/eclipse
has ELF 32-bit libraries.

The swt .so libraries are shipped as part of the swt jars.  Those also
appear to be 32-bit.  This is probably a bogus error caused by something
else (like not being able to load gcj-specific libraries with sun's
jdk?)

Hi

We have experienced quite a few variants of issues affecting a lot of
users that were fixed by a simple rm -fr ~/.eclipse, which is why I
suggested it here as well. On a related note -data affects the
workspace; not where it finds your personal configuration.

Anyhow, back to your issue:
 * Does it mention any name of the library it cannot load?
 * What is the output of: 

find /usr/share/eclipse /usr/lib/eclipse/ -name '*.so' -exec file {} \;

seemingly 6 other people have confirmed this as also effecting them so I
do not believe it to be related to my setup

Yeah the original commandline I was testing is created a new directory
in /tmp and using that as workspace (mktemp -d)

Re-tested with no ~/.eclipse, but still having the same problem.

$ rm -rf ~/.eclipse
$ eclipse -debug -consolelog -console -data `mktemp -d`

Hi

The 3.5.1+repack~2-0ubuntu1version of swt for i386 only contains 32-bit
libraries; can you please try to remove/rename your ~/.eclipse folder
and start eclipse again using an empty workspace?

May not be easy to sense from dependencies -- the only JVM installed on
the system is sun-java6-jdk, package version 6-16-1.  No GCJ or other
VMs.
