Uppdated to 1.0.1 today, my code worked before instalation of 1.0.1, with 1.0.0.
Swithced back to 1.0.0 still same problem.

Would really appriciate some help, been searching for solutions for hours now and getting nowhere :confused: .
Thanks in advance

Is there something you're not telling us?
Like code...

This works fine for me.

Arduino.h needs a capital A.

Doesn't need, used it without before with success, but tried with it and still the same errors unfortunally.

It needs it on most (ie non windows) OSs.

Ok, Im running Windows if that helps anyone to give me a hint about whats wrong.

Seems like i've solved it, included Arduino.h in the .cpp not the header.

I just had the same error. With that for a hint, I solved it differently. Just had to move the {library}.h file to the top of the .cpp file, so that it was before the struct that was referencing size_t.

That is what I get for doing 'cleanup' on working code. :~
