c++ builder XE2

Post by geanni » Thu 20 Oct 2011 15:00

HI,

I have just installed new XE2 c++ builder (Embarcadero® RAD Studio XE2 Version 16.0.4276.44006 ) and MyDac 7.0.2. The operating system is w7 x64.

I get a compiler error saying ([BCC32 Error] CRVioTcp.hpp(44): E2238 Multiple declaration for '_fastcall SocketException::SocketException(int)').

Is it a problem, or am I missing something?

thanks,
Geanni

This is the full stack:

Please, download the latest MyDAC build from our site and check if this problem still exists.

Exactly same problem with Builder XE

Post by javier4517 » Mon 24 Oct 2011 09:53

Hi
Last Friday 21/11, we downloaded the MyDAC 7.0.2 trial version for Builder XE.
We were trying a very simple example, just a form with a grid and a TMyConnection, TMyTable and TMyDataSource connecting to a MySql table. That's it, zero line of code. When building the app, we are getting the below error.
I would really appreciate your help, as we’re in the middle of an investigation process to decide in the purchase of some new software like XE2 and we are quite interested on your product, but we really need to be able to run a lot of tests and the fact that we cannot even compile a simple app like this, it is not really helping.
Regards
Javier

We have reproduced the problem. This is a problem of MyDAC Trial Edition. To solve the problem, you should remove the following code from the CRVioTcp.hpp unit:

Code: Select all

class DELPHICLASS SocketException;
#pragma pack(push,4)
class PASCALIMPLEMENTATION SocketException : public System::Sysutils::Exception
{
	typedef System::Sysutils::Exception inherited;
	
protected:
	int FErrorCode;
	
public:
	__fastcall SocketException(const System::UnicodeString Msg, System::TVarRec const *Args, const int Args_Size, int ErrorCode);
	__fastcall SocketException(int ErrorCode);
	__property int ErrorCode = {read=FErrorCode, nodefault};
public:
	/* Exception.CreateRes */ inline __fastcall SocketException(int Ident)/* overload */ : System::Sysutils::Exception(Ident) { }
	/* Exception.CreateResFmt */ inline __fastcall SocketException(int Ident, System::TVarRec const *Args, const int Args_Size)/* overload */ : System::Sysutils::Exception(Ident, Args, Args_Size) { }
	/* Exception.CreateHelp */ inline __fastcall SocketException(const System::UnicodeString Msg, int AHelpContext) : System::Sysutils::Exception(Msg, AHelpContext) { }
	/* Exception.CreateFmtHelp */ inline __fastcall SocketException(const System::UnicodeString Msg, System::TVarRec const *Args, const int Args_Size, int AHelpContext) : System::Sysutils::Exception(Msg, Args, Args_Size, AHelpContext) { }
	/* Exception.CreateResHelp */ inline __fastcall SocketException(int Ident, int AHelpContext)/* overload */ : System::Sysutils::Exception(Ident, AHelpContext) { }
	/* Exception.CreateResFmtHelp */ inline __fastcall SocketException(System::PResStringRec ResStringRec, System::TVarRec const *Args, const int Args_Size, int AHelpContext)/* overload */ : System::Sysutils::Exception(ResStringRec, Args, Args_Size, AHelpContext) { }
	/* Exception.Destroy */ inline __fastcall virtual ~SocketException(void) { }
	
};

#pragma pack(pop)

That solvesd the problem. Also the paid version worked from the first attempt.

Thanks,
