fatal error: WConstants.h: No such file or directory

Hello I have got some problems with upload the firmware to my Arduino

I have downloadet the JArduino-0.1.7 zip file and copy the arduino folder to the libery by the Arduino on my Computer.

Then i oppened the Arduino ide 1.6.6 (windows 64 bit)

I connected the Arduino UNO and launch the ide.

on File> Examples> Jarduino> JArduino Firmware.

the programm started... but if i compile and want to upload this error will be shown:

Arduino: 1.6.6 (Windows 8.1), Board: "Arduino/Genuino Uno"

C:\Program Files (x86)\Arduino\libraries\JArduino/JArduino.h:24:24: fatal error: WConstants.h: No such file or directory

include "WConstants.h"

                    ^

compilation terminated.

Did you download version 1.7 or 1.7b?

1.7b should fix the problem. You need to include Arduino.h instead of WConstants.h.

However, it might be that Arduino changed the way they deal with version number and that piece of code might not work anymore:

//JArduino.h
#if defined(ARDUINO) && ARDUINO >= 100
    #include "Arduino.h"
#else
    #include "WConstants.h"
#endif

//JArduino.cpp
#if defined(ARDUINO) && ARDUINO >= 100
    #include "Arduino.h"
#else
    #include "WProgram.h"
#endif

If you did download v1.7b, simply include Arduino.h in your JArduino.h and JArduino.cpp and see if it helps.

v1.7b compiles with Arduino 1.6.6
