I recently purchased a pcDuino 3B and I am very pleased with the Board so far. I can use the preinstalled arduino IDE to program the board from the board and run programs.
However, when I came to use I2C, it generated a load of errors with the built-in libraries when I tried to compile. I don't know why it did this, it does it when trying to compile any program using I2C. Here is the error list (Yes, I am using an Adafruit display library that works fine with exactly the same sketch on my laptop):

/usr/share/arduino/hardware/arduino/pcduino/cores/arduino/WString.h:42:14: note: String::String(unsigned char, unsigned char)
It seems that no one else is having this issue.
Just to clarify, the issue is not with my code or the library, it compiles fine on my other computer running WINDOWS but same Arduino version (1.5.3), same sketch code and same library code.
Help much appreciated, thanks!
