Compiler/CC2530: Error[e46]: Undefined external "XXXX::?relay" referred in XXXX

Tool/software: TI C/C++ Compiler

I'm using a CC2530 like a PAN Coordinator at Non beacon-enabled network Start. I use file hex and C in TIMAC1.5.2.43299 like a Lib. I take steps to program a PAN Coordinator like guide in 802.15.4 MAC API. I use IAR.

my code here:

#include "hal_types.h"
#include "mac_api.h"
#include "mac_nv.h"

void main(void)
{
MAC_MlmeResetReq(TRUE);
}

when i Make Project (F7), i have Error: 

Error[e46]: Undefined external "MAC_MlmeResetReq::?relay" referred in start_network ( D:\IAR\CC2530\start_network\Debug\Obj\start_network.r51 )

Please show me how to resolve this error
