Firmata on TM4C123GXL Tiva-C launchpad compile error

[chintanp 0]

I am trying to run the Firmata library code on my TIVA-C launchpad TM4C123GXL. Firmata located here: https://github.com/energia/Energia/tree/master/libraries/Firmata 

 

Now I have followed the instructions on the page, but still get the error when trying to compile the StandardFirmata. 

 

 

The error is :
