I am a brand new user. I was going through the tutorial on creating Libraries:
and I discovered that the text mentioned #include "WProgram.h" a few times.
The compiler could not find this header. I searched the whole Arduino directory and I could not find it. I did find the "Arduino.h" header and it seems to work (at least now it complies).
Did you change the header from "WProgram.h" to "Arduino.h"?
I suggest that you change this as new users will get hung up trying to get their own libraries to compile - I took me over an hour to find this documentation error [smile].
Please write to my e-mail email@example.com when you have read this bug report so that I know that you received it.
