[sqlite] problem with undefined reference

[dark0s dark0s]

Hi all, I am newbye in sqlite programming.
I written a little C program to begin with sqlite, and I posted it below:

#include <stdio.h>
#include <stdlib.h>
#include <sqlite3.h>

void main() {

  int rc, i;
  sqlite3* db;
  sqlite3_stmt* stmt;
  char* sql;
  const char* tail;

  rc = sqlite3_open("prova.db", &db);
  if (rc) {
    fprintf(stderr, "E' impossibile aprire il file %s\n", sqlite3_errmsg(db));
    sqlite3_close(db);
    exit(1);
  }

  sql = "create table modulo(id, nome, classe, istanza);";
  rc = sqlite3_prepare(db, sql, strlen(sql), &stmt, &tail);
  if (rc != SQLITE_OK) {
    fprintf(stderr, "Errore SQL: %s\n", sqlite3_errmsg(db));
  }

  rc = sqlite3_step(stmt);

  while (rc == SQLITE_ROW) {
    for (i = 0; i < sqlite3_column_count(stmt); i++)
      fprintf(stderr, "'%s' ", sqlite3_column_text(stmt, i));
    fprintf(stderr, "\n");
    rc = sqlite3_step(stmt);
  }

  sqlite3_finaqlize(stmt);
  sqlite3_close(db);

}

So, when I compile above program the result is:

bash-3.1# gcc CreaDB.c -o CreaDB
CreaDB.c: In function 'main':
CreaDB.c:21: warning: incompatible implicit declaration of built-in function 
'strlen'

CreaDB.c:(.text+0x16c): undefined reference to `sqlite3_finaqlize'
CreaDB.c:(.text+0x17b): undefined reference to `sqlite3_close'
collect2: ld returned 1 exit status


What is the problem?

Thanks,
savio
