I had problems with my pc and i have to format it.I was working with arduino Eclipse on Mac and on Windows.
I have some projects going on .I installed the arduino on Mac and eclipse c/c++ i installed avr plugin as i had before also rxtx and terminal.I have setted the paths for avrdude correctly.I have cloned my repositories from mercurial that worked fine to the workspace(arduinoCore and the rest projects) and i tried to built them.
I have semantics error, the compiler does not understand the arduments and gives me errors at functions like pinMode() digitalWrite() Serial.print().
What can i do "Arduino.h" is included already. The arduinoCore project is the same that it is provided at the playground tutorial for setting arduino with eclipse.
At windows i get the same error plus that i can not create the .hex file
