C++ undefined vtable

Hello,

I'm using KDS 1.1.1 and KSDK 1.0.0 all updated.

I'm trying to port this library: adafruit/Adafruit_10DOF · GitHub (adafruit/Adafruit_Sensor · GitHub) to the Kinetis (FRDM-K64F board to be exact).

The problem is that:

- I don't know C++ very well

- it gives me an error and I don't know what to do.

The error:

<path>/Adafruit/Adafruit_Sensor.h:139: undefined reference to `vtable for Adafruit_Sensor'

The code is this:

class Adafruit_Sensor {
public:
// Constructor(s)
void constructor();

// These must be defined by the subclass
virtual void enableAutoRange(bool enabled) {};
virtual void getEvent(sensors_event_t*);
virtual void getSensor(sensor_t*);

private:
bool _autoRange;
};

and the cpp file contains:

#include "Adafruit_Sensor.h"

void Adafruit_Sensor::constructor() {
}

Some ideas?

Thanks Bye

Giacomo

OK, problem solved, it was the Adafruit_sensor class not written very well (no distructor,...).
