Using TOrasession without VCL

[Hoeh3010]

Hallo,

I want to use the ODAC Components without the VCL inside of an own class . But unfortunately I receive a link - error "DATA.DBCONSTS.OBJ" can not be opened. In the class header I am including "DbAccess.hpp" and "Ora.hpp" and in the corresponding cpp-File I am using: #pragma link "DBAccess" and #pragma link "Ora".
I hope that somebody is able to help me. - Oh, I am using C++ Builder 10.2 for designing my programs.
Best regards

We tested the work of ODAC 10.1.3 without using VCL and found no problems. For testing, we created the simplest console application, the source code of which is below:

Code: Select all

#include "Ora.hpp"

#pragma hdrstop
#pragma argsused

#ifdef _WIN32
#include <tchar.h>
#else
  typedef char _TCHAR;
  #define _tmain main
#endif

#include <stdio.h>

#pragma link "Ora"

int _tmain(int argc, _TCHAR* argv[])
{
	TOraSession *OraSession = new TOraSession(NULL);
	OraSession->Server = "<your TNS Name>";
	OraSession->Username = "scott";
	OraSession->Password = "tiger";
	OraSession->Connect();
	return 0;
}

We successfully compiled this application and connected to Oracle DB using it. Please repeat the same steps in your test environment and let us know the results.

Thank you for your answer. I tried it out, but I got the same error message.
So I guess, that there could be something wrong with my compiler and linker settings, but I have no idea, what I should change.

Perform the next step. Open the * .cbproj file of your project in any test editor and find the "FrameworkType" tag in it. Specify in it the following value:

Code: Select all

<FrameworkType>None</FrameworkType>

Save the result and compile the project in RAD Studio again

Hallo,
the specified tag is OK. I made my class now inside a vcl-based application and tried to build my program and it worked. So I guess, that compiling with the VCL framework does something different. It seems, that one or more paths will not be found.
