#include EFI_STATUS EFIAPI UefiMain(IN EFI_HANDLE ImageHandle, IN EFI_SYSTEM_TABLE *SystemTable)
{EFI_STATUS Status &＃61; EFI_SUCCESS;EFI_FIRSTDRIVER_PROTOCOL *gf;Status &＃61; gBS->LocateProtocol(&gEfifirstdriverProtocolGuid,NULL,&gf);if(EFI_SUCCESS &＃61;&＃61; Status){Print(L"success to locate protocol\n");}else{Print(L"failed to locate protocvol\n");}gf->Func1(gf);Print(L"ia in protocol is %d\n",gf->ia);return Status;
}

testlib.dsc的     [libraryclass]    块中加上
