Re: [cdt-dev] Influencing where CDT is looking for include paths

["Florian Kaltner" <metr0n@xxxxxx>]

Hi Andrew!

Thanks for your response!
I am aware that i am kind of abusing the pre-building index feature in a way it was not meant to be used.

The problem is, that the source which was used to build the PDOM takes to long if indexed locally.
In addition to that checking out the entire source is quite time-consuming.

So the idea was to use the prebuilt index to get code-assist features while not having the entire source stored locally. This works quite well so far.
The problem now is just that you don't want to navigate to every include file in order to open and view it manually.
(Since the files should be in the index and so it should be possible to get the path to them)
It would be nicer hitting F3 popping up a new editor window showing its content.

Is setting an include path the only way to do that?
Or can i influence the action triggered by hitting F3 somehow?

Thanks,
Florian

    hi Florian,

     the pre-built indexes in CDT 4.0/5.0 are intended to address the use-case
    where the pre-built
    content is non-changing(*1) and disjoint (*2) from the workspace - e.g.
    SDK or library headers.

    In that scenario, references to types outside the workspace will be
    resolved to the pre-built content
    and navigation features will direct to file paths obtained from there when
    appropriate. This doesn't
    mean include paths should not be set up correctly in the project model -
    project builders
    will still need that information to correctly compile. You can do that
    via:

    http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse.cdt.doc.user/reference/cdt_u_prop_general_pns_inc.htm

    thanks,
    Andrew
