I apologize if this is an obvious question or if it has been asked before. I'm new to Arduino IDE. I am confused about the build process, specifically, the include paths. I looked here: http://www.arduino.cc/en/Hacking/BuildProcess but couldn't find the answer to my problem.
I am developing for the esp8266 (refer: esp8266-github). Within "WiFiClient.", the following lines are present:
#include "Client.h" #include "IPAddress.h"
Since these files don't exist within the "src/" directory there, the pre-processor should look in the other default include paths, correct?
Now the file "IPAddress.h" is present in "Arduino/cores/esp8266/IPAddress.h" as well as "Arduino/hardware/arduino/avr/cores/arduino/IPAddress.h"
So how does it know which one to pick? Which config file, include path or some other setting determines this?
