Dear all,

I had many projects compiling without any trouble using odac 6.90.0.53.
After upgrading oracle to 6.90.0.54 ind installing dbmonitor 3 (no db monitor before), most projects refuse to compile because of:
error ws2def.h(208): E2238 Multiple declaration for sockaddr
...

Here is a sample dm.cpp:

Code: Select all

#include 
#pragma hdrstop


#include "DM.h"
#include "GDB.h"

//-----------------------------------------------------------------------------
#pragma package(smart_init)
#pragma link "DBAccess"
#pragma link "MemDS"
#pragma link "Ora"
#pragma link "OraSmart"
#pragma link "OraAlerter"
#pragma link "DAAlerter"
#pragma resource "*.dfm"

TFDM *FDM;
//---------------------------------------------------------------------------
__fastcall TFDM::TFDM(TComponent* Owner)
	: TDataModule(Owner)
....

What is strange: Adding a

Code: Select all

#include

just after

Code: Select all

#pragma hdrstop

solves the problem.

What is strange: Adding a

Code: Select all

#include

Code: Select all

#include "DM.h"

does NOT solve the problem.

the dm.h only holds

It even seems that adding

Code: Select all

#include

as last include of any form holding odac components causes an error (and added as first include causes no error).

So it seems has to be included manually at the top of each module... and it worked fine before (!).

Do you have a better solution?

We could not reproduce the problem. Please send to support*devart*com a complete small sample that demonstrates the problem.

The same with BCB2010! It seems that this error occurs in combination with Indy, when you use Indy components and ODAC components in the same form.

To fix the problem:
open the DBMonitorMessages.hpp file (from \Include);
replace the following line:

Code: Select all

#include

with

Code: Select all

#include
