RE: [cdt-dev] pulling in extern definitions with CDT parser

["Schorn, Markus" <Markus.Schorn@xxxxxxxxxxxxx>]

Peter,
The indexer works out of the box on top of a CDT-project. All you need to achieve is to programmatically create a CDT project for the code you are 
interested in and it will get indexed.

You can run eclipse without UI and you do not need a UI to have projects and translation units. 

Markus.
