I read #7 when I joined the forum, and this is exactly what I did in my post. I'm assuming it's because it isn't a full sketch, so for convenience I have posted it below.
Please keep in mind that I am just attempting to get a sensor to work here, nothing more. It doesn't really matter what my code is because the problem caused when loading the OneWire library, and that is literally the first thing I do.
I don't expect anyone to have much experience with this device, so I'm only looking to trouble someone else who has attempted this already. If you want to reproduce the error then run Arduino 1.5.5 beta with the RFduino files installed, import the OneWire library, change the board to RFduino, write the sketch below and then click verify:
// DS18S20 Temperature sensor
Then change the board to Arduino Uno and click verify and it compiles just fine.
This is that code compiled for my Arduino Uno:
And this is the build failing for my RFduino:
I am yet to write any more code because it doesn't compile for the device I was intending to use...
