# Compile Error - help please

I am attempting to get the Withrottle Server for DCC++ working and keep getting the following error:

In file included from C:\Program Files\Arduino\libraries\ESP8266WiFi\src/ESP8266WiFiSTA.h:28:0,

compilation terminated.

Hoping someone can assist me with this

Do you have all your include libraries in the right location?
After installing libraries, did you restart the IDE?

.

Have you googled that error message? It appears that you are trying to compile a sketch that is not intended to be used on the hardware that you have.
