eclipse problem

Hej, I already installed eclipse with arduino and I tested the Blink program successfully the problem is not recognizing Serial Serial1, Serial2 comunications.

I've checked headers looking for Serial definitions but i'm finding nothing. Any ideas?

By the way i've got headers from arduino v21 and i'm running OSX.

Thanks

Already fixed, seems Serial and other libraries are c++ so I need to run it on a C++ Project not a C one...
