MySensors library 1.4 fails to compile when run on RPi (solved)

[Zerphed]

Hey,

I am new with the MySensors library, and I just installed it on my Raspberry Pi, where I have the Arduino framework (1.0.1) as well. I was going to try out some of the examples using the Arduino IDE, but for some reason it seems that the library fails to compile when I try to verify the code. When running for example the BatteryPoweredSensor example the compiling fails to the following error:

I simplified the source to see if it's a specific call that would cause the issues, but it doesn't seem that way. The source that I am using is pasted under.

// This is an example that demonstrates how to report the battery level for a sensor
// Instructions for measuring battery capacity on A0 are available in the follwoing forum
// thread: http://forum.micasaverde.com/index.php/topic,20078.0.html

#include <SPI.h>
#include <MySensor.h>

int BATTERY_SENSE_PIN = A0;  // select the input pin for the battery sense point

MySensor gw;
unsigned long SLEEP_TIME = 900000;  // sleep time between reads (seconds * 1000 milliseconds)
int oldBatteryPcnt = 0;

void setup()  
{
   // use the 1.1 V internal reference
   analogReference(INTERNAL);
   gw.begin();

   // Send the sketch version information to the gateway and Controller
   gw.sendSketchInfo("Battery Meter", "1.0");
}

void loop()
{
   // get the battery Voltage
   int sensorValue = analogRead(BATTERY_SENSE_PIN);
   gw.sleep(SLEEP_TIME);
}

Anyone have any ideas how to get the library working?

Alright,

I figured it out. It was no more complicated than updating the Arduino IDE and the avr-gcc compiler from the outdated versions (Arduino IDE 1.0.1) automatically installed by the apt-get.

The instructions for updating the Arduino IDE and the compilers can be found here: https://nicohood.wordpress.com/2015/01/24/installing-avr-gcc-4-8-1-and-arduino-ide-1-6-on-raspberry-pi/
