eclipse cdt tools installing error

Question

I am trying to install the CDT plugin on an exisitng 32-bit installation of Eclipse on Ubuntu Jaunty. I've tried both web-update and standalone-package install and both fail with the following error-

This may be related to bug 285743: as explained in this thread

What happens is that P2 fails to correctly setup osgi.install.area, because it doesn't strip 'plugins' part from the path. I saw this happen when eclipse.ini file in target directory didn't have '-startup' option in it.

Take a look into your eclipse.ini file if it contains -startup option like this:

-startup
plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20080819.jar

Note: if this is the case, you can refer to "proper" eclipse.ini to avoid any settings-related problem (for eclipse3.4 or 3.5.x): see "good" eclipse.ini.
