[CLAM] Oscillator

[Lucas Vallejos]

Hola,
tinc un problema al definir un objecte de la classe FFT_rfftw. El que 
tinc, resumit, és:

...
#include "WindowGenerator.hxx"
#include "FFT_rfftw.hxx"

#include "DataTypes.hxx"
#include "Oscillator.hxx"
#include <iostream>
using std::cout;
using std::endl;
using std::cerr;

using namespace CLAM;

//comencen les definicions de funcions, i en una d'elles tinc:

        FFTConfig fftcfg;
        fftcfg.SetAudioSize(1024);

        FFT_rfftw mifft(fftcfg);


i al compilar obtinc:

/home/lucas/clam/CLAM/obj//home/lucas/clam/CLAM/examples/theBand/ex2.o: 
In function `CLAM::OscillatorConfig::HasSamplingRate(void) const':

collect2: ld returned 1 exit status
make[1]: *** [ex2] Error 1
make[1]: Leaving directory `/home/lucas/clam/CLAM/examples/theBand'
make: *** [ex2] Error 2

Tinc el mateix error quan intento definir una finestra de la classe 
WindowGenerator. No sé què hi té a veure la classe Oscillator...
Algú hem pot dir alguna cosa?
Gràcies
Lucas
