万利EK-STM32F在IAR4.42 下移植UCOSII老是出现下面问题；（在mian里面只用了OSInit()）
Error[e46]: Undefined external "OS_CPU_SR_Save" referred in os_core ( G:\STM32 no ku\UCOS\project\EWARM\Debug\Obj\os_core.r79 )
Error[e46]: Undefined external "OS_CPU_SR_Restore" referred in os_core ( G:\STM32 no ku\UCOS\project\EWARM\Debug\Obj\os_core.r79 )
Error[e46]: Undefined external "OSDebugInit" referred in os_core ( G:\STM32 no ku\UCOS\project\EWARM\Debug\Obj\os_core.r79 )
Error[e46]: Undefined external "OSCtxSw" referred in os_core ( G:\STM32 no ku\UCOS\project\EWARM\Debug\Obj\os_core.r79 )
 
void main(void)
{
  RCC_configuration();
  GPIO_configuration();
  USART_configuration();
  OSInit();
  while(1);
}
麻烦各位大虾看下是什么原因；

问题解决了，原来只是缺少了个oc_cpu_a.asm
