Help! Arduinos using ESP8266 as a host

[mt7725]

Hi,
I'm trying to compile and upload the DuinoCoin_Arduino_Slave.ino code to a Arduino uno r3 board. But I get these compiler errors.
error.txt Please let me know how resolve the compiler errors (the Arduino_Code.ino code complies without any errors).

Regards,
Mahendra
