I have often found that some of the compiler errors that are shown are missing details.

For example I just got this compiler error


Compiling 'RealTimeClockTest' for 'Arduino Mega 2560 or Mega ADK'
RealTimeClock.cpp.o : : In function `DateTime::day() const':
RTClib.h : LastDateTimeRead'
RealTimeClock.cpp.o : : In function `RealTimeClock::ReadDateTime()':
RealTimeClock.cpp : LastDateTimeRead'
RealTimeClock.cpp : LastDateTimeRead'
Error creating .elf


But if I turn on verbose in the options and then run the actual command to do the compile I can see the following


...\RealTimeClock.cpp.o: In function `DateTime::day() const':
c:\Dev\Arduino\arduino-1.0.1\libraries\RTClib/RTClib.h:16: undefined reference to `RealTimeClock::LastDateTimeRead'
..\RealTimeClock.cpp.o: In function `RealTimeClock::ReadDateTime()':
..\RealTimeClock.cpp:31: undefined reference to `RealTimeClock::LastDateTimeRead'
..\RealTimeClock.cpp:31: undefined reference to `RealTimeClock::LastDateTimeRead'


As you can see your parsing of the messages is removing important information.

In the case of the 

In function `DateTime::day() const':
RTClib.h : LastDateTimeRead'

should be


In function `DateTime::day() const':
c:\Dev\Arduino\arduino-1.0.1\libraries\RTClib/RTClib.h:16: undefined reference to `RealTimeClock::LastDateTimeRead'


and

RealTimeClock.cpp.o : : In function `RealTimeClock::ReadDateTime()':
RealTimeClock.cpp : LastDateTimeRead'
RealTimeClock.cpp : LastDateTimeRead'


should be


..\RealTimeClock.cpp.o: In function `RealTimeClock::ReadDateTime()':
..\RealTimeClock.cpp:31: undefined reference to `RealTimeClock::LastDateTimeRead'
..\RealTimeClock.cpp:31: undefined reference to `RealTimeClock::LastDateTimeRead'


It would really help if this could be addressed as it is pretty hard to determine the errors without a lot of extra work.

I am using 1.1401.26

hi Tim

I will try to reproduce it and send you a sample.

I also was using 1.01
