There is a list of include paths.
Some are in bold and are project specific.
Others are builtin:
For example:
/usr/include/C++/4.6/
/usr/include/x86_64-linux-gnu
etc
If I delete:
work/.metadata/.plugins/org.eclipse.cdt.make.core/*.sc
The paths are automatically rescanned when Eclipse launches.
I have gcc 4.6 and gcc 4.7 installed side-by-side.
When Eclipse rescans it only finds the 4.6 headers and not the 4.7 ones.
My question is this: By what mechanism does Eclipse determine the list of builtin include paths? (and hence why is it only finding the 4.6 headers and not the 4.7 headers?)

Built-in Settings. CDT will try to detect built-in compiler symbols and include paths running the compiler with special options and parse the output of this special run. Most compilers provide such an option to print built-in include paths and symbols.
Select C/C++ General -> Path and Symbols. Select Includes tab. In Languages list, select 'GNU C' or whatever C compiler tool chain you use. Press 'Add...' button and add the directory for the include files.
This is controlled by the settings on Project->Properties->C/C++ Build->Discovery Options. By default, Eclipse will call g++ to discover the include directories. The first instance of g++ on the path will be the one that gets invoked. You can always set the full path to the compiler you want it to use for your project.
