Eclipse CDT Intellisense Not Updating C++

Question

I am working on a C++ project using Eclipse Kepler V4.3.1 with the CDT plugins on Fedora. Up until yesterday, everything seemed to be working fine, but now when I make a change Intellisense/Content Assist doesn't seem to see it. (Note that this is not the same problem with getting autocomplete to make suggestions that I have seen others post about.)

For example, if Eclipse picks up on an error like passing an invalid argument to a function, when I then go and fix the error Eclipse continues to complain about it. It continues to show me the old line before I made the change. If I open that same file with Emacs or gedit, I see that in fact the change was made and saved.

Here is what I have tried without success:

• Right click on the project > Index > Rebuild
• Right click on the project > Index > Freshen All Files
• Right click on the project > Index > Update with Modifies Files
• Restarting Eclipse
• Restarting the entire machine
• Checking for software updates and installing them (plus restarting).

Any ideas?

For others who might run into this issue, I wish I had a better solution but here is what solved it:

• Delete the entire build directory
• Clean the project
• Delete the files I had been working on and re-add them.
• Right click on the project > Index > Rebuild
• Restart Eclipse

I'm not sure which part actually did it since I had also previously installed updates, but things seem to be working again.
