What confuses me here is the reference to DallasTemperature library and Bseries.cpp which as far as I can see is not part of my program. Never referenced in the sample code or in the OneWire code. I would also expect that a sample code would work directly.
The code in the example that can be choosen from inside Arduino IDE
File/Examples/OneWire/DS18x20_Temperature
which is
#include <OneWire.h>
// OneWire DS18S20, DS18B20, DS1822 Temperature Example

PaulS:
What Arduino are you compiling for? Unless you have a Due or a Micro, you don't need to be using 1.5.x.
For a UNO, on 1.0.5, I got just this one "error" message:
Binary sketch size: 6,592 bytes (of a 32,256 byte maximum)
And I also get that result on PC at my office. I do notice in this case there are no reference to including this
-IC:\Users\JAN\Documents\libraries\DallasTemperature
but why trying to include DallasTemperature on my computers at home ? Nowhere in the code is that stated.
