C++ builder 下使用mysql++的问题？？

[rediron]

在c++ builder下使用mysql++的问题：
1、在不使用#include <vcl.h>时可以编译成功，包括mysql++1.79版自己带的例子;
2、但是一使用c++ builder的VCL支持时编译就出错，出错信息
[Linker Error] Unresolved external '_mysql_num_rows' referenced from D:\TO_ME\MYWORK\DATABASE\UNIT1.OBJ
[Linker Error] Unresolved external '_mysql_num_fields' referenced from D:\TO_ME\MYWORK\DATABASE\UNIT1.OBJ
[Linker Error] Unresolved external '_mysql_data_seek' referenced from D:\TO_ME\MYWORK\DATABASE\UNIT1.OBJ
但是屏蔽掉这行就没没有编译时的错误
//Result res1 = query1.store();

源文件:
#include <vcl.h>
#include <windows.h>

#include <sqlplus.hh>
#pragma hdrstop

#pragma argsused
int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved)
{
Connection con("tradedb","127.0.0.1","odbc","");
Query query1 = con.query() ;
query1 << "select * from orders";
Result res1 = query1.store(); /*就是这行出错，去掉就没问题*/
return 1;
}

请高手帮助！！
