在Eclipse中找不到用于连接MySQL的C++代码的库

我正试图运行我从互联网上得到的这段代码，但我会得到一个错误

c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -llibmysql.lib' 

和

c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -lmysqlcppconn-static.lib

我正在使用Eclipse和MinGW连接MySQL。我添加了：

C:Program Filesboost
C:Program FilesMySQLMySQL Connector C++ 1.1.3include
C:Program FilesMySQLMySQL Server 5.6include

到include目录和

C:Program FilesMySQLMySQL Server 5.6lib
C:Program FilesMySQLConnector C++ 1.1.2libopt

至图书馆目录（-L）。我还添加了

libmysql.lib
mysqlcppconn-static.lib

附加依赖项（-l）。

我的代码是：

#include <iostream>
#include <cstdio>
#include <cstdlib>
using namespace std;
#include <stdlib.h>
#include <Windows.h>
#include <mysql.h>
#include "mysql_connection.h"
#include <cppconn/driver.h>
#define host "localhost"
#define username "root"
#define password "root"
#define database "tests"
int main()
{
    MYSQL* conn;
    conn = mysql_init( NULL );
    if( conn )
    {
        mysql_real_connect( conn, host, username, password, database, 0, NULL, 0 );
    }
    MYSQL_RES* res_set;
    MYSQL_ROW row;
    unsigned int i;
    mysql_query( conn, "SELECT * FROM tbl_clients WHERE id = 1" );
    res_set = mysql_store_result( conn );
    unsigned int numrows = mysql_num_rows( res_set );
    if( numrows )
    {
        row = mysql_fetch_row( res_set );
        if( row != NULL )
        {
            cout << "Client ID  : " << row[0] << endl;
            cout << "Client Name: " << row[1] << endl;
        }
    }
    if( res_set )
    {
        mysql_free_result( res_set );
    }
    if( conn )
    {
        mysql_close( conn );
    }
    return 0;
}
