I upgraded to the 12.04 beta yesterday. Now, when I try to start Eclipse, I get the splash screen and then this error message:

An error has occurred. See the log file /home/gabriel/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/1335382319394.log .

The log file says something like this: 

java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: 
    no swt-gtk-3740 in java.library.path
    no swt-gtk in java.library.path
    Can't load library: /home/gabriel/.swt/lib/linux/x86_64/libswt-gtk-3740.so
    Can't load library: /home/gabriel/.swt/lib/linux/x86_64/libswt-gtk.so

followed by many more error messages.

The /home/gabriel/.swt/lib/linux/x86_64/ directory exists, but is empty. I also tried reinstalling eclipse with no success.

Any ideas?

I have got the same issue in an AMD64 machine (Ubuntu 12.04). and solved it by a workaround:

copy: files containing '3740' in /usr/lib/jni/libswt-*3740.so to ~/.swt/lib/linux/x86_64/

But, be sure the packages : libswt-gtk-3-java & libswt-gtk-3-jni are installed.

sudo apt-get install libswt-gtk-3-jni libswt-gtk-3-java

And

sudo cp /usr/lib/jni/libswt-*3740.so ~/.swt/lib/linux/x86_64/

if you have a 32 bits based system : sudo cp /usr/lib/jni/libswt-*3740.so ~/.swt/lib/linux/x86/

    wow this actually worked for me too (Intel core i5, 64 bit ubuntu 12.04) thanks a lot! – vallllll May 01 '12 at 09:57

    Worked great for a 32-bit system. Using: sudo cp /usr/lib/jni/libswt-*3740.so ~/.swt/lib/linux/x86/ . Thanks and update your answer please. – Binarylife May 03 '12 at 09:24

    It really works for me either (Ubuntu precise 64 bit). I had created soft links instead of copy. – masuch May 04 '12 at 23:11

Try running

sudo update-alternatives --config java

and selection open jdk. This would probably work.

Also for me it works; I done: 

cd ~/.swt/lib/linux/x86_64
ln -s /usr/lib/jni/libswt-atk-gtk-3740.so
ln -s /usr/lib/jni/libswt-gtk-3740.so
ln-s /usr/lib/jni/libswt-pi-gtk-3740.so

and so, I created 3 symlink in the folder ~/.swt/lib/linux/x86_64

Now Eclipse works fine!

echo "-Djava.library.path=/usr/lib/jni" >> /etc/eclipse.ini

fixed it for me.

Thanks for the great instructions. I added symlinks like this instead, to make sure it picks up all 3740:

cd ~/.swt/lib/linux/x86_64

for i in /usr/lib/jni/*3740*.so ; do ln -s $i; done

I made symlinks to the missing libs and everything worked fine. It ended up looking like this...

    libswt-atk-gtk-3740.so -> /usr/lib/jni/libswt-atk-gtk-3740.so
    libswt-gtk-3740.so -> /usr/lib/jni/libswt-gtk-3740.so
    libswt-pi-gtk-3740.so -> /usr/lib/jni/libswt-pi-gtk-3740.so

Seems to work.
