[eclipse] failed to launch eclipse on ubuntu 12.04

由於ubuntu的default JDK是Open JDK, 但由於要編譯Android 的關係, 我把JDK換成了Oracle JDK, 而導致安裝好Eclipse後 在啟動Eclipse會失敗, 失敗訊息如下

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/hamersun/.swt/lib/linux/x86_64/libswt-gtk-3740.so

Can't load library: /home/hamersun/.swt/lib/linux/x86_64/libswt-gtk.so





解決方法是

on 64-bit

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

on 32-bit

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/
