I wanted to pass along the only way I found to get PDT installed and working on Ubuntu Gutsy...
I had no luck with the Eclipse from the Ubuntu repositories, and certainly no luck with anything related to GCJ. I've spent two days now on it.
What I did that finally appears to be working:
- remove all GCJ and Java stuff
- install Sun's 1.5 JDK
- download the J2EE Europa version
* ( at this point, Eclipse works) *
- add PDT as a new Remote Site to Eclipse's updater, and force it to download the files only from the PDT site itself (due to some bug with mirrors -- see http://dev.eclipse.org/blogs/wayne/2007/09/18/php-for-nothing/)
I then had PDT installed and working, and could then follow the instructions from this blog post for adding Subclipse and JSEclipse. I didn't bother with Zend Debugger, because I think PDT should be able to use xdebug ok.
