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