How to compile the developer esp8266 gateway

[kr0815]

After long reading through the forum, it sems like i have to install the developer version of the Wifi-Gateway
But how to install it ?
I have Arduino 1.6.6, Core 2.0.0 - should be ok ?

I tried a fresh / portable install, do i need packages from the stable build or is everything i need in the developer package ?

i copied many folders back / forth, deleted some, now i´m stuck with

In file included from C:\Users\KR\Desktop\arduino-1.6.6\libraries\MySensors\MySensor.cpp:21:0:

C:\Users\KR\Desktop\arduino-1.6.6\libraries\MySensors\MySensor.h:284:4: error: #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.
