problem with interfacing arduino

while compile the LIFA_Base it showing error -

"Arduino: 1.6.6 Hourly Build 2015/09/01 03:14 (Windows 7), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

int RECV_PIN = TKD2; // the pin the IR receiver is connected to

Error compiling.

  enabled in File > Preferences."

This happens because LIFA is old and unsupported.  You should upgrade to LINX (http://www.labviewmakerhub.com/linx).  You do not need to compile any Arduino code to use the default functions provided in LINX (when using Windows).

Regarding the errror specifically, you can search on these forums since this has been asked and answered many times.
