undefined reference to `myclass::function()'

[NicoCaldo]

So,

I'm trying to compile my main.cpp that includes three modules. For instance I got a module counter with this .h file

#include <systemc.h>

SC_MODULE(counter) {

	sc_in<bool> clk; //porta ingresso clock
	sc_in<bool> load; //porta ingresso load
	sc_in<bool> clear; //porta ingresso clear
	sc_in<sc_uint<8> > din; //porta ingresso dato (intero 8 bit)
	sc_out<sc_uint<8> > dout; //porta uscita dato (intero 8 bit)

	unsigned int countval; //valore del contatore (intero senza segno)

	void counting(); //funzione conteggio (il mio processo)

	SC_CTOR(counter) { //costruttore di counting()

		SC_METHOD(counting); //costruttore del mio processo attraverso metodo (meglio del thread)

		sensitive << clk.pos(); //sensibile al fronte del clock, positivo
	}
};

now, when I run the compiler with

g++ -I/usr/local/systemc-2.3.3/include -L/usr/local/systemc-2.3.3/lib-linux64/ -lsystemc -lm -o out main.cpp

but I got this error

/tmp/ccz92lN5.o: In function `counter::counter(sc_core::sc_module_name)':
main.cpp:(.text._ZN7counterC2EN7sc_core14sc_module_nameE[_ZN7counterC5EN7sc_core14sc_module_nameE]+0xba): undefined reference to `counter::counting()'

How do I fix it?

Ok find the issue.

I needed to compile all the .cpp dependencies as well with

g++ -I/usr/local/systemc-2.3.3/include -L/usr/local/systemc-2.3.3/lib-linux64/ -lsystemc -lm -o out counter.cpp shifter.cpp testbench.cpp main.cpp
