Can you help me? Im desperate because i need this for a college work.

Answer 1

Here's how it worked for me

Install both eclipse and eclipse-pde. These are the packages I have installed:

sudo apt-get install eclipse eclipse-jdt eclipse-pde eclipse-platform eclipse-platform-data eclipse-rcp

Add the site: http://eclipsefp.sourceforge.net/ocaml/site.xml as a software source

Help->Install New Software
Select OCaml

You get this:

I suspect you're missing something that's in these:
eclipse-jdt eclipse-pde eclipse-platform eclipse-platform-data eclipse-rcp
