Hi! Could anyone help please with the following Arduino compiler report :-
core.a(main.cpp.o): In function `main':
C:\Users\Rod\REPRAP1\Original MD90 files\3D Printing\arduino-1.0.1-windows\arduino-1.0.1\hardware\Melzi\cores\arduino/main.cpp:11: undefined reference to `setup'
C:\Users\Rod\REPRAP1\Original MD90 files\3D Printing\arduino-1.0.1-windows\arduino-1.0.1\hardware\Melzi\cores\arduino/main.cpp:14: undefined reference to `loop'
What have I done?
