Home -> Community -> Usenet -> c.d.o.server -> Oracle OCI programming and Borland C++ Builder
Afternoon,
this is an answer not a question :o)
As you may know, Oracle dropped support for Borland Compilers in OCI some time back. Well, it isn't all that hard to set up again.
I'm running 9i Release 2 Enterprise Edition on this PC at work and I am using Borland C++ Builder 6 to 'play' with OCI programming - I intend to build a set of components eventually, but I need to know what I'm doing first !
I remember trying in the past to get OCI to work - but had no luck, however, this time I decided not to give in so easily. I was depressed to find that the old Borland folder under <oracle_hjome>\oci\lib has gone - looks like only MS Visual C is supported - and we all know that MS and Borland have a different OMF format and there is much wailing and gnashing of teeth to get Borland talking to DLLs etc created with MSVC and vice versa.
There are docs on Metalink which go into great detail about these differences and how it can screw up your life to use a Borland compiler - but I suspect these are now out of date.
Here is what you have to do instead (the following uses my paths - adjust for your setup) :
Open a DOS window
cd e:\oracle\ora92\oci\lib
mkdir borland
cd borland
Assuming that the CBuilder bin directory is on your path .....
implib -a oci.lib <oracle_home>\bin\oci.dll exit
That has created an import library to be added to any OCI projects you want to create. The '-a' bit is required as it prepends an underscore to the exported module names in the dll. This is what used to cause so many problems with MS/Borland libraries and stuff in the past.
The rest is simple, run up C++ Builder and open one of the Oracle samples - I used CDemo6 - you'll be asked to create a project to run it, do so then save it as BOR_CDemo6.
Project | options and on the directories tab, add <oracle_home>\oci\include to the includes path.
Then Project | add to project and add <oracle_home>\oci\borland\oci.lib to the project.
Compile & run - et viola (as French musicians would say) an OCI program compiled and running with Borland tools.
Now you've got that working you have no excuse for not downloading the OTL (Oracle Template Library) and using it instead - it is up to release 4.0.36 now and supports Oracle 9i.
I really hope this helps someone - I could have done with this help years ago myself. I'm off to try my hand at 'proper' OCI programming for a bit now. <insert big smug grin here>
Cheers,
Norman.
