I'm running Sketches on a Linux box. I have tried to compile the basic node example and get this error, along with other programs I'm wanting to use. Any pointers why would be appreciated.
I have an RFM69CW which will run on an Arduino Mega.

You need to install the RFM69 library in your arduino libraries folde
See these links for more on that:

I have - This is directly from the examples using the library within Sketches too.

I found the issue but not sure how to resolve it - I am using an Arduino Mega 2560 board so when it hits this part of the header file, it doesn't define these variables, resulting in the error.
// INT0 on AVRs should be connected to RFM69's DIO0 (ex on ATmega328 it's D2, on ATmega644/1284 it's D2)
#if defined(__AVR_ATmega168__) || defined(__AVR_ATmega328P__) || defined(__AVR_ATmega88) || defined(__AVR_ATmega8__) || defined(__AVR_ATmega88__)
#define RF69_IRQ_PIN 2
#define RF69_IRQ_NUM 0
#elif defined(__AVR_ATmega644P__) || defined(__AVR_ATmega1284P__)
#define RF69_IRQ_PIN 2
#define RF69_IRQ_NUM 2
#elif defined(__AVR_ATmega32U4__)
#define RF69_IRQ_PIN 3
#define RF69_IRQ_NUM 0
#endif
If defines are missing it means the lib was not targetted for that MCU and that MCU is not supported at the moment. You are welcome to add the defines and make any additions necessary and submit a pull request so we can add them to the library.
Just to quickly follow up in case anyone else with an Arduino Atmega board wants to use this module. To make it work make the following change in RFM69.h:
Line 34
#if defined(__AVR_ATmega168__) || defined(__AVR_ATmega328P__) || defined(__AVR_ATmega88) || defined(__AVR_ATmega8__) || defined(__AVR_ATmega88__) || defined(__AVR_ATmega2560__)
The last defined is all you need to add. I've confirmed the rest is compatible. The only thing I haven't completely resolved yet is the SPIFlash - if you remove the manufacturer ID it seems to work but I'm not 100% convinced.
A couple of notes. There is an activity LED on pin 13. SS is pin 53.
To wire it up:
MISO --> pin 50
MOSI --> pin 51
SCK --> pin 52
NSS --> pin 53
DIO0 --> pin 2.
I'm not entirely certain how to make a pull request so I will leave it to the powers that be to decide how to incorporate the details :)
Hope this helps someone.
