Hello, when I make a new empty c++ project I get these warnings:

Quote:

Invalid project path: Include path not found (/usr/include/c++/4.7.1/x86_64-unknown-linux-gnu).
Invalid project path: Include path not found (/usr/lib/gcc/x86_64-unknown-linux-gnu/4.7.1/include-fixed).
Invalid project path: Include path not found (/usr/lib/gcc/x86_64-unknown-linux-gnu/4.7.1/include).
Invalid project path: Include path not found (/usr/include/c++/4.7.1/backward).
Invalid project path: Include path not found (/usr/include/c++/4.7.1).

I'm using GCC 4.7.2. Its include paths are missing from the project so when I include <iostream> Eclipse tells me that it cannot be found but the project builds fine.

Why is CDT unable to detect the version of gcc correctly? Any suggestons how to fix it?

Open Windows->Preferences and go to page C++->Build_>Settings. Open the tab Discovery and select GCC Builtin Compiler Settings. The click the "Clear Entries" button on the right side. Eclipse will then recheck the include paths (I assumed that the command gcc will call gcc-4.7.2).
