Eclipse 4.4.1 Not seeing changes to custom header file [message #1496184]

I have a simple project I'm building the bones of at the moment and this is my first time using Eclipse in nearly a decade so this is probably some stupid issue.

My code in my project is fairly simple thus far (all C++ source files). I have two projects but each shares a common custom header file so I've placed this custom header file in a subfolder in the workspace folder and added this path to both the projects' include search paths list.

The header file defines a few structs and a few defines just to complete some strings. ie. #define datcontrol_shm "/datcontrol_shm" and similar for a few others.

Now when I initially wrote the header file and the initial source code everything was fine, but then I decided to change up the shared memory allocation and made some changes to the header file. I changed the nomenclature for the #defines and the struct names.

However, when I edit the source files to use the changes made to the header file Eclipse complains bitterly because it apparently thinks I've made no changes to the header file - even though it's saved. I've tried refreshing the source and the projects, but nothing is working. I'm getting numerous "Symbol could not be resolved" errors on #defines used in the source that are in the new header file, while similarly if I put old #defines in the source file that are no longer even in the header the errors go away.

How can I make Eclipse realize there has been a change to this header file?

Thanks everyone.

Aww, seems I needed to Right-Click => Index => Freshen All Files (or maybe Update with Modified Files). That seems to have cleared it up. I'd think such a function would happen with Refresh, but perhaps I'm misunderstanding Refresh.
