Having eclipse CDT automatically detect g++ version in PATH

Question

I have some C++ projects that I build on both g++ 4.2.4 and 4.4.3. I want eclipse to inspect the g++ version and construct the /usr/include/c++/${g++-VERSION} directory in the Paths and Symbols configuration of my CDT project. Is there some way to do this?

Answer 1

Figured it out in the Project Settings:

C/C++ Build -> Discovery Options -> Enable "Automate discovery of paths and symbols"
