Trying to run application which uses Oracle libraries on Visual Studio 2005

Question

I am trying to run existing application which uses OCCI libraries - for example in Linker->Input the project has specified oraocci10.lib.

I am using Visual Studio 2005.

This is what I did.

1. Downloaded 10.2.0.5 package from here(1st and 5th packages):

   http://www.oracle.com/technetwork/topics/winsoft-085727.html

2. Set environment variables (I have Oracle client installed as it seems):

   ORACLE_HOME C:\app\g\product\11.2.0\client_2

   TNS_ADMIN C:\app\g\product\11.2.0\client_2\Network\Admin

3. Set paths to oracle libraries in my project:

   C/C++->General->Include directories: D:\instantclient_10_2\sdk\include

   Linker->Additional Library directories: D:\instantclient_10_2\sdk\lib\msvc

4. In Code Generation->Runtime Library: Multi-threaded DLL (/MD)

My application compiles but I get run time errors. When I run this application as a standalone exe (without compiling the executable, I was given that exe separately also) it works fine, connects with the database, etc.

So something must be wrong how I configured Visual Studio against these OCCI libraries. I would really appreciate some help where I have gone wrong, as I am nearing point where I can't guess what I have done wrong.

Thanks in advance

Answer 1

If what you wrote in your question is accurate, your versions of Instant Client and the OCCI client do not match, and they have to. So either you're using 10.2.0.2 or 11.2.0.2, but you can't mix and match. You will tear your hair out trying to get this to work otherwise.
