Re: [cdt-dev] CDT and Qt Creator

Our product has serge's flexible resources stuff in it, and it works
well. It effectively gives you VS style projects + the Eclipse
resource model - local history, team support (if linked resources are
supported), etc all working with CDT editing, managedbuild & debug
(CDI).
I believe CDT will be able to cope with all this just fine. There
may be a couple of places which still don't handle linked resources
properly, but when I was working on this, I went on a blitz of
submitting / committing fixes...

James
