红色部分报错：[BCC32 Error] Unit1.cpp(35): E2451 Undefined symbol 'TIdUDPListenerThread'
但我用右键转到定义，TIdUDPListenerThread类是在IdUDPServer.hpp头文件中定义的，能跳转过去，且该头文件在Unit1.h里已包含（蓝色部分）。
IdUDPServer.hpp对类TIdUDPListenerThread的定义内容如下：
class PASCALIMPLEMENTATION TIdUDPListenerThread : public Idthread::TIdThread
{
typedef Idthread::TIdThread inherited;
protected:
Idsockethandle::TIdSocketHandle* FBinding;
int FAcceptWait;
System::DynamicArray<System::Byte> FBuffer;
// System::TArray__1<System::Byte> FBuffer;
System::UnicodeString FCurrentException;
System::TClass FCurrentExceptionClass;
System::TObject* FData;
TIdUDPServer* FServer;
virtual void __fastcall AfterRun(void);
virtual void __fastcall Run(void);
public:
__fastcall virtual TIdUDPListenerThread(TIdUDPServer* AOwner, Idsockethandle::TIdSocketHandle* ABinding);
__fastcall virtual ~TIdUDPListenerThread(void);
void __fastcall UDPRead(void);
void __fastcall UDPException(void);
__property int AcceptWait = {read=FAcceptWait, write=FAcceptWait, nodefault};
__property Idsockethandle::TIdSocketHandle* Binding = {read=FBinding};
__property TIdUDPServer* Server = {read=FServer};
__property System::TObject* Data = {read=FData, write=FData};
