Eclipse C/C++ Shows Errors but Compiles?

Question

So I am building some Arduino code in eclipse, as described in Your Second Arduino Project, but every time I use an Arduino library, such as Serial, Eclipse underlines my function names, claiming they cannot be resolved. However, the code actually compiles, so I'm kind of at a loss as to why Eclipse thinks the functions are missing. If anyone has any idea on how to solve this problem it would be appreciated. Thanks beforehand.

EDIT: I should have been more specific, Eclipse underlines the METHODS inside the Arduino libraries. So if I use Serial.println("hello");, it underlines println() and claims it cannot be resolved. Then it compiles just fine and the method works when uploaded to the arduino board.

EDIT2: I found my error, turns out I was trying to use some C++ functions in a C file, and eclipse didn't like it; I renamed to .cpp and all the red disappeared ;) Thanks for your help!

Eclipse does not work as well with C++ as it does with Java, but it should warn you about issues once you press "Rebuild" in the menu bar.

Try that, and see if it resolves your problem.
