Function definition not found (even if they exist) - c++

Question

Here's my main:
#include "terremoto.h"
int main(){
std::string filename, zona;
std::ifstream in_stream;
std::ofstream out_stream;
nodo *elenco, *filtroZona;
std::list<Terremoto> elencoDoppio;
float K;
// caricamento dati tramite file
std::cout << "Inserire nome file da caricare\n";
getline(std::cin, filename);
in_stream.open(filename);
// elenco è la linked list con tutti i terremoti
elenco = carica_elenco(in_stream);
// filtro per zone tramite input da tastiera
std::cout << "Inserire zona da filtrare\n";
std::cin >> zona;
filtroZona = filtro_zona(elenco, zona);
std::cout << filtroZona;
// copia di elenco in una double linked list (elencoDoppio)
elenco_to_list(elenco, elencoDoppio);
stampa_dlist(std::cout, elencoDoppio);
// filtro per soglia di magnitudo tramite input da tastiera
std::cout << "Inserire soglia magnitudo (filtra per >=K)\n";
std::cin >> K;
filtra_magnitudo(elencoDoppio, K);
stampa_dlist(std::cout, elencoDoppio);
return 0;
}
here's my terremoto.h:

Terremoto.h - from line 43 on:
stampa_slist(...) : VSCode suggests "function definition for 'stampa_elenco' not found" (that's not the name of the function, I also tried rebooting but the error stays there.
elenco_to_list(...) : Like above, but this time the function name is correct.
stampa_dlist(...) : Again, it states "stampa_elenco()" is missing a definition, and again that's not the name.
When compiling, I only get an error with stampa_dlist(...) and it's the following:
undefined reference to `stampa_dlist(std::ostream&, std::__cxx11::list<Terremoto, std::allocator >&)'
found in the main, obviously.

Answer 1

As Richard Critten suggested, there was obviously an issue with the "const" in the definition.
No matter how much you check, sometimes the combination of being completely new to CS and the need of a break really hit :D
Sorry for the stupid question, but thanks for opening my eyes ahah
