I have ARDUINO 1.6.12 Software and Arduino YUN device.
I have the latest ubidots library as pointed by https://ubidots.com/docs/devices/ArduinoYUN.html#arduino-yun
I get compilation error when I link the library.

Arduino: 1.6.7 (Windows 10), Board: “Arduino Yún”

@jagstock

We fixed a problem in compilation in some pc’s, now it will working fine.
You can download the latest version of the library from github and upload it to YUN.

I apologize for the error it will not happen again.

Hi Metavix

Just now downloaded everything and trying to compile example sketch UbidotsSaveValue.ino but there are some warnings. In case the feedback helps, please see below.

yeah @jamestoher you can ignore these warnings.
The program will compile and upload to the device.
