What does Eclipse and Google Web Toolkit have in common? Both uses libswt-pi-gtk library. This library doesn’t work too well with Ubuntu Drapper Drake on AMD64. On Eclipse the following error would display:
libswt-pi-gtk-3235.so: cannot open shared object file: No such file or directory
When attempting to use NetBeans 5.5 rc1 with GWT NetBeans plug-in, the following error would display:
libswt-pi-gtk-3139.so: cannot open shared object file: No such file or directory
The file actually exists on the path specified by the error output. Here is a file command output:
libswt-pi-gtk-3139.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), stripped
A Google search showed this is a known issue for Eclipse. Fortunately, I was able to start Eclipse using root and run NetBeans with GWT on an older 32-bit system.
