Currently the eclipse-cdt package is missing from Ubuntu 9.10. To install cdt support do the following:
Fire up eclipse:
- Help->Install New Software
- Click Add
- In location add: http://download.eclipse.org/tools/cdt/releases/galileo
You should be able to select this now from the drop down box titled “Work with:”
Follow it through and it will install what you need. My previous C/C++ view was ghosted so I added it again.
