sqlite c++体系结构x86_64的未定义符号

我正在Mac osx上运行一个sqlite c++演示。我从下面显示的网页上复制了代码。

参考：http://www.tutorialspoint.com/sqlite/sqlite_c_cpp.htm

源代码是

//     
#include <stdio.h>
#include <stdlib.h>
#include <sqlite3.h>
#include <fstream>
#include <string>
using namespace std;
static int callback(void *NotUsed, int argc, char **argv, char **azColName){
    int i;
    for(i=0; i<argc; i++){
        printf("%s = %sn", azColName[i], argv[i] ? argv[i] : "NULL");
    }
    printf("n");
    return 0;
}

int main(int argc, char* argv[])
{
    sqlite3 *db;
    char *zErrMsg = 0;
    int  rc;
    char *sql;
    string str;
    /* Open database */
    rc = sqlite3_open("test.db", &db);
    if( rc ){
        fprintf(stderr, "Can't open database: %sn", sqlite3_errmsg(db));
        exit(0);
    }else{
        fprintf(stdout, "Opened database successfullyn");
    }
    /* Create SQL statement */
    str = "CREATE TABLE location(country text, state text, city text );CREATE TABLE weather(temp real, tempunit text);";
    strcpy(sql,str.c_str());
    /* Execute SQL statement */
    rc = sqlite3_exec(db, sql, callback, 0, &zErrMsg);
    if( rc != SQLITE_OK ){
        fprintf(stderr, "SQL error: %sn", zErrMsg);
        sqlite3_free(zErrMsg);
    }else{
        fprintf(stdout, "Table created successfullyn");
    }
    sqlite3_close(db);
    return 0;
}

输出为

我已经在笔记本电脑上安装了sqlite库。有人能解释一下吗？谢谢
